What Is a Pulse Jet Bag Filter?

Pulse jet bag filter, also known as pulse jet baghouse or pulse jet dust collector, is a self-cleaning dry filter system. The pulse jet dust collector cleaning system uses the burst of compressed air to remove particles and dust from the surface of the internal filter medium. Pulse jet bag filters are the most common air pollution control equipment in the workplace, including factories, plants, warehouses and other industrial or commercial environments to meet workplace air quality and safety requirements.

The pulse jet dust collector does not contain any moving parts, so it provides reliable continuous operation and excellent filtration efficiency. It is designed to effectively collect and remove potentially harmful particulates, gas and smoke, or it will enter the working environment or atmosphere. The popularity of pulse jet dust collector is due to its simple operation, low energy consumption and low maintenance requirements.

The pulse air bag filter gets its name from the short burst or "pulse" of compressed air used to clean the bag or filter. In the pulse jet system, the dust is collected on the outer surface of the bag/filter, where a piece of dust is usually formed. Based on time or based on the pressure drop of the pressed powder at the appropriate thickness, the activation sequence of a controller pulses the inside of the compressed air filter bag, one (or more) row(s), knocking dust and powder are freely filtered out by gravity into the hopper for removal. The mechanics of the compressed air pulse and the induced airflow of the additional air produce shock waves and ripple effects on the filter bag, which enhances the mechanical force of the initial shock wave of the compressed air itself to remove dust particles off the fabric.

Advantages of pulse jet collector

The pulse jet filter system has several advantages compared with other types of dust collection systems. Its basic advantage is that the pulse jet has the ability to clean online. The duration of the compressed air pulse is usually between 100 and 200 microseconds, which effectively promotes 24/7 operation without interrupting the ventilation of dusty air, and there is no downtime to clean the bag filter.

The pulse jet collector is incredibly versatile in terms of the temperature, pressure, and gas stream chemistry range of its application. Pulse jet dust collectors can be made from a wide selection of metals-carbon steel, stainless steel, aluminum, or special alloys such as Inconel and Hastelloy-to meet the specific needs of any manufacturing environment, from chemical compatibility to wear resistance to food grade or FDA requirements.

Pulse jet bag filter is the most used dust collector in the industry, and its high dust removal efficiency has laid the foundation for its position in most devices. Manufacturing environments such as chemical and mineral processing plants, grain processing plants, food processing plants, steel plants, metal processing and manufacturing plants, asphalt plants, and many other industries benefit from pulse jet bag filters to maintain air quality and meet safety standard.

Cyclone Bag Filter

Industrial workplaces are prone to dust and pollutants, which increases the need for proper ventilation. Although small dust particles are always excluded, many studies have shown that they may endanger the lives of workers and long-term exposure to it. Dust and small pollutants can affect the respiratory system and other parts of the body, leading to serious health problems. In order to avoid all these problems, dust collectors are now used in industrial workplaces. Cyclone dust collector is a kind of dust collector commonly used in workplaces. Why are they popular? Do they have any advantages? Yes, the cyclone dust collector has many advantages, which makes it more popular than other types of dust collectors.

The cyclone dust collector is designed to effectively capture dust and debris generated by machining operations, such as planing or joining.

Various advantages of cyclone dust collector

Over the years, several advantages of cyclones have made them popular. Here are some of them:

No need for expensive filters: Most dust collectors use expensive filters that require regular maintenance or replacement. However, the Cyclone bag filter uses centrifugal force to eliminate or remove particles in the airflow. Therefore, these dust collectors are a wise choice for areas exposed to high levels of dust, pollutants and air irritants.

Safety design: Two-stage dust collectors are considered safer than most other dust collectors. Why? The dust bag of the dust collector often releases huge dust mist during the cleaning process. However, when the main collection point of the cyclone was cleared, debris and heavier debris were released.

Maintenance-free: It is not easy to clean filters or bag houses in industrial workplaces. These filters or bag houses are taken to isolated areas for cleaning. Most companies outsource this task to a third-party contractor to ensure the smooth execution of the process. In addition, the high cost of replacing the filter, coupled with the cost of third-party services, may have a negative impact on the company's budget. In this case, the use of cyclone dust collector is an economical choice, and its maintenance cost is low.

Material recovery: In some industries, the dust collected in the dust collector may include gold dust or silver dust. Because of its economic value, it is reused or recycled. In this case, it is not recommended to use a standard filter, because the material may be lost in the filter, and the cyclone dust collector does not use a filter, and the collected valuable materials can be recycled through the discharge valve.

When a collection bag is emptied from a standard dust collector, as soon as the collection bag is removed, a large amount of dust will emerge from the collection bag. Since the main collection point of the cyclone contains only heavier debris, it is much cleaner and safer to empty the main collection bag.

Since the cyclone dust collector greatly reduces the number of particles contacting the filter element, the frequency of cleaning and/or replacing the expensive filter is greatly reduced.

Cyclone dust collector is a kind of mechanical dust collector. Dust removal equipment is not limited by dust concentration. According to the dust concentration, the thickness of dust particles can be used as one-stage dust removal or multi-stage dust removal. It is widely used in various industrial and mining enterprises, workshops, construction sites, and has good effects on metallurgy, casting, crushing, sandblasting, tunneling, cement, building materials, chemicals, food, refractory materials, etc.
