5 Things To Consider When Buying a Cyclone Dust Collector

The cyclone dust collector is the simplest and lowest cost air-material separator. Most common in grain and wood processing facilities where fibrous dust is managed, cyclones are often used as low-maintenance stand-alone dust collectors that do not require compressed air for cleaning. When the size of the dust exceeds 20 microns, the cyclone can achieve a very high collection efficiency. Cyclone dust collectors are often used as pre-filtration systems to reduce the dust load to downstream bag filters and drum dust collectors.

There are many reasons to consider installing a cyclone dust collector to meet equipment dust collection requirements. Here are 5 factors that need to be considered in advance.

Dust control needs

The size of the cyclone dust collector system required is proportional to the volume of air flow required to capture and transport particulate matter. A dust control assessment of the facility can help determine the size and type of system required. How large is the particulate contaminant to be collected? Does the ventilation air need to be discharged or returned to the manufacturing area? Is the dust generated in a specific process or continuously? Such an assessment will help determine the cyclone dust removal system that meets your needs.

Budget considerations

Once the assessment of plant dust control needs is completed, companies will be able to determine what type and size of cyclone system they need to purchase. Cyclone dust collectors are cheaper than bag filters or cartridge dust collectors, but can they meet the equipment's long-term demand for particulate matter (PM) collection efficiency? Can bag filters be reliable without the need for upstream cyclone? Compared with the cyclone/dust collector system, there is only one air-material separator, the pressure drop of the entire system will be lower, thereby reducing the fan horsepower, thereby saving energy in the long term. If the application requires cleanliness, then maintenance costs need to be weighed.

Pre-filtering needs

In any facility, the dust and particle collection efficiency is related to the size of the particles in the air and their distribution in the air or gas stream. Before purchasing a system, consider the size of the particles circulating in the plant or factory. Cyclone is very effective in removing large particles (diameter exceeding 10 to 20 microns). If the application is to collect larger particles, such as 200 mesh, an independent cyclone may be completely acceptable. In other cases, when the pollutants contain particles with a diameter of less than 10 microns, by reducing the dust load and pre-filtering coarser substances, the cyclone can be used as a "pre-cleaner" for bag filters and cartridge dust collectors.

System footprint

An important consideration is where the cyclone dust collector will be installed. The independent cyclone separator is a relatively compact, efficient and economical air-material separator. However, if a downstream dust collector is also required in the system, this requires more floor space and usually more headroom. Cyclone dust collectors and bag dust collectors or cartridge dust collector systems will cause the collected dust to have two separate discharge points, which will complicate the entire system.

Health benefits

Of course, the first consideration is the health benefits of eliminating dust in the workplace. Once spread through the air, these dust and particles will bring many health hazards to people who come into contact with them. Fine dust particles composed of chemical substances in various materials such as metal, wood, silica, minerals, etc., may cause respiratory diseases, poisoning, allergic reactions, and certain cancers. If the cyclone dust collector meets the budget requirements economically, it can greatly improve the working conditions of the staff.

Dust Collector Maintenance

After the bag filter is maintained and installed and used for 1-2 months, the bag will become longer. After the bag becomes slack. On the one hand, it is easy to be in contact with the adjacent cloth bag to be worn, and on the other hand, in the slack part, the cloth bag generates holes due to dust accumulation and friction. In addition, due to the disappearance of the pulling force, the cleaning effect is degraded, and clogging of the bag mesh occurs. Therefore, check the equipment 1-2 months after installation and adjust the tension. Although the spring-type bag filter may not need to be adjusted, it should be checked frequently. After one year of operation, replace the inappropriate spring.

The bag filter is a dry dust filter device, suitable for collecting fine, dry, non-fibrous dust.

Ancillary equipment pipes and dust hoods are important ancillary equipment, which can be easily communicated in the early stage of operation; judging by abnormal vibration, poor suction, and poor operation.

There are two kinds of mine dust collectors: wet dust collectors and dry dust collectors. Wet dust collectors have the disadvantage of secondary pollution and are inconvenient to manage. Especially the characteristics of easy freezing of water in winter have become a major disadvantage; dry dust collectors The device is easy to operate, easy to maintain, and has a high dust collection rate.

At the beginning of operation, pay attention to whether the exhaust fan is reversed, and lubricate the fan in time. Although most fans are equipped with automatic starting devices to reduce accidents, the bag dust collector is maintained but there is no automatic start. Because the fuse of the power supply is blown after the start failure, the motor runs in single phase, and the burnout accident occurs from the beginning of the operation.

In addition, the rapid change of gas temperature and the maintenance of bag dust collectors also have an adverse effect on the fan, and this situation should be avoided. Because the temperature change may cause the fan shaft to change, forming an unbalanced state of operation, causing vibration. Moreover, when the operation is stopped, if the temperature drops sharply, there is a risk of vibration when it is restarted.

The starting of the equipment plays an important role in normal operation, observe carefully and act with caution.

What Is an Industrial Dust Collector?

Industrial dust collector is a kind of air pollution control equipment used in factories, workshops, warehouses and other industrial or commercial places to meet the safety requirements of the environment and workplaces. An effective dust collection system controls, reduces and removes potentially harmful particles and smoke in the gas or air and the surrounding environment during the production process. This equipment is specially used to purify and filter harmful dust and fine particulate pollutants released into the working environment or the atmosphere to maintain and improve air quality.

The types of pollutants vary from industry to industry. Therefore, the industrial dust collector is designed for the extraction method required by each industry. The working principle of the dust collection system is generally to suck dust and particles in the air through a filter. The filter first captures and separates the substances, and then discharges the purified air back to the workplace or the environment. The goal of each design application is essentially the same-filter, separate and capture dust and particulate matter, and release purified air.

The basic components of the dust collector include a blower, a dust filter, a dust collector cleaning system, a dust collector and a dust removal system. Five common types of dust removal equipment are fabric filter baghouses, inertial separator (such as mechanical cyclone), drum collector, wet scrubber and electrostatic precipitator.

Bag filters come in various designs and are the most commonly used system due to their 99% efficiency.

Dust collection is vital to many industrial sectors such as woodworking, agriculture, food processing, pharmaceuticals, recycling, cement and rock products, metal manufacturing, mining and chemical processing. Dust collectors called filter receivers are an important part of the processing system, used in many thermal and downsizing applications and as receivers for pneumatic conveying.

Pulse jet dust collector is another bag type dust collector system, in order to meet the needs of industrial applications, a variety of designs are used. The bag cleaning system is cleaned by a rapid, high-pressure air jet, sending shock waves or impacts through the bag, crushing and discharging the dust cake for processing. The rapid pulsation of air allows the fan to run continuously, so the system is generally not divided. Pulse jet models are the most common type of industrial dust collector because of their ability to be easily customized, their ability to handle a wide range of temperatures and pressures, and their high collection efficiency.

The cyclone dust collector is an inertial separator that separates dust from the airflow by centrifugal force. By generating a cyclone in the cyclone collection chamber, the air is purified. An intense circular airflow resembling a vortex pushes dust particles to the wall of the cyclone separator, and then slides to the bottom of the hopper for collection. The cyclone system can remove heavier and larger particles mixed with fine dust. They are often used as pre-cleaners before the baghouse.

What Is a Screw Conveyor

A screw conveyor or auger conveyor is a mechanism that uses a rotating screw, called "flighting", installed in a tube or trough to move liquid or granular materials. They are used in many bulk cargo handling industries. Screw conveyors are often used horizontally or slightly inclined in modern industry as an effective way to move semi-solid materials, including food waste, wood chips, aggregates, grains, animal feed, boiler ash, meat and bone meal, and municipal solid waste and many others. The first form of screw conveyor is Archimedes' screw, which has been used to pump irrigation water since ancient times.

They usually consist of a slot or tube containing a helical blade around a shaft, driven at one end, and called a solid shaft screw at the other end. Other types are open screw or shaftless screw drive at one end and free at the other end. The volume transfer rate is proportional to the speed of the shaft. In industrial control applications, the device is usually used as a variable rate feeder, changing the rotation rate of the shaft to feed the measured rate or amount of material into a process.

When space permits, the use of inclined screw conveyors is a very economical method of lifting and conveying materials. When the inclination angle increases, the capacity of a given unit decreases rapidly. The general rule of thumb is 45 degrees or less, otherwise the material will eventually fall backwards over the flight and not convey to reach the intended destination.

Some of its advantages are:

The screw conveyor can handle all kinds of bulk materials from slow to free flowing.

The screw conveyor can have multiple inlet and outlet points. Bulk materials can be transported and distributed to different locations as needed. Sliding gates or valves can be used to control the flow into and out of the screw conveyor.

When a screw conveyor is used as a metering device, it is considered a screw feeder. The screw feeder is used to start a material process to meter the product from the silo or hopper.

The screw conveyor is very compact and suitable for crowded locations. Screw conveyors have no return similar to belt or drag conveyors.

The screw conveyor is completely enclosed to contain the product and prevent spillage. Screw conveyor can be used in horizontal, vertical or any inclined position depending on the situation

Screw conveyors can be used to mix various products together and crush large pieces.

Screw conveyors can be used to cool, heat or dry products in transit. According to the heat transfer requirements, the screw conveyor can be jacketed or hollow flight design to provide the necessary heat transfer for the application.

Screw conveyors can be designed to be steam tight or to maintain internal pressure. This is very important when transporting toxic or dangerous products, such as those in the chemical industry.

Screw conveyors can provide an air lock between upstream and downstream equipment.

Background Of Concrete Pump

The concrete pump is a tool for conveying liquid concrete.

For more than half a century, concrete pumps have slowly replaced other methods of conveying liquid concrete. Many different concrete pump designs were developed in the first half of the 20th century, but in 1957 the two-cylinder hydraulic concrete pump was invented by Friedrich Wilhelm Schwing. This design principle is adopted by almost all other manufacturers and is still the standard design worldwide.

The working principle of the pump is that one piston draws liquid concrete from the hopper into the cylinder, while the other piston simultaneously pushes the concrete into the drain pipe. Valve, determine which cylinder is open to concrete hopper, which one is open to the discharge pipe switches over every time the piston reaches the end point and the process continues.

Concrete conveying pumps are particularly important in the revolutionary construction of large high-rise buildings. In the past, people used cranes to hoist large buckets (or hoppers) filled with concrete to where needed. A crane can only lift one bucket at a time, and usually can hold about 2 cubic yards of concrete.

There are many advantages to pumping concrete over this bucket and crane system. The speed of pumping concrete is faster than the bucket lifting, which also means that a constant top and the concrete supply hose can be positioned wherever they need liquid concrete can be poured directly out of the hose needs instead of distributing two cubic yard mound of concrete over the desired area.

The advantages of concrete pumping than lifting it up in a skip by a crane:

The volume of concrete poured per hour is much larger. The crane can lift 12 cubic meters per hour.

Constant flow. Today's concrete pumps can pump concrete as fast as truck mixers. In many cases, it can even be as fast as a two truck mixer.

Reduce waste of working hours. People placing concrete need to wait for the next batch of jumps to be moving or being refilled at the bottom. The person at the bottom just waits for the skip to come back down, while it is moving or unloading at the top. The continuous flow of the concrete pump means less waiting around.

The crane can perform other tasks. The crane can transport steel products, scaffolding, formwork and all other necessary building materials to where needed, instead of hoisting concrete buckets up and down.

Place the concrete directly where you want it. The placement hose can be moved so that the concrete can be placed wherever needed.

Lower labor costs. Because concrete can be placed exactly where it is needed, only a small number of people are needed to distribute the concrete-unlike when a platform dumps the load and then someone needs to move the concrete to the place where it is needed.

Faster setup time.

When To Use The Cyclone Dust Collector In Front Of The Bag Filter

Cyclone Dust Collector manufacturer will share this article with you.

Cyclone bag filter can reduce the maintenance cost of the bag filter and reduce the downtime

Mechanical dust collectors were once the industry standard for dust collection and air pollution control. However, with increasing attention to air quality, the US Environmental Protection Agency's regulations on dust collection have pushed the manufacturing industry toward higher efficiency capabilities of fabric bag filters, cartridge filters, and other dust collection equipment that use filter media. This change will undoubtedly help reduce the amount of harmful gases emitted into the atmosphere during the manufacturing process. Unfortunately, the use of these fabric filter bag collectors is not without cost. The limitations of filter media (such as humidity, heat, and high particle volume) increase the challenge of successful dust collection. In addition, the cost of replacing filter bags or cartridges, maintenance issues, and expensive pulse jet control for cleaning the filter material will increase. For many people, the solution to these problems is to use a mechanical dust collector before the final stage of filtration.

The mechanical dust collector uses cyclone airflow to separate particles from the airflow. The centrifugal force generated by the rotating air stream throws dust from the air stream towards the wall of the collector. In a typical cyclone, particles hit the wall of the collector and fall on the funnel below to collect. The purified air is discharged through the top of the collector. Although this form of collection can efficiently process large, dense particles, the extremely fine dust lacks the inertia to escape the airflow and is subsequently carried out with clean air.

Filter media dust collectors, such as cloth bag and cartridge filters, use fine filter media to remove dust from the airflow. The dust-laden air is sucked into the collector, where it passes through the filter medium and the particles are intercepted. Before cleaning or replacing the filter, dust will accumulate on the filter. The purified air is discharged from the collector.

The environment involved in many production processes makes it very difficult to rely entirely on plastic bags. A heavy dust load can be a nightmare to maintain the filter media collector.

Processes involving high-temperature exhaust gases can also damage the filter media collector. The high-temperature air discharged from foundries, glass factories, and power plants can burn most filter media used in cloth bag factories. Although high-temperature filter bags and filter cartridges are available, they can be an expensive addition and are still not completely immune to heat. Used as a spark arrester, the cyclone dust collector can be placed before the baghouse to reduce the temperature and particle load of the airflow before it enters the final stage filter.

Although mechanical dust collectors may not be necessary in every application, the benefits of this proven technology are obvious. As emission standards become more stringent and process costs continue to rise, any available advantages should be considered. By comparing the cost of materials, labor, and downtime with the cost of the cyclone separator, you can decide whether you need this equipment.
