Dust Collector Filter Bags
- Using dust-collecting bag filter material, the dust cannot penetrate the filter material. It is a surface filtration process. It starts as filtration and remains in the filtration state for a considerable period of time.
- The duration of the cleaning process is highly advantageous. It ensures that the filter material does not become clogged, and it does not alter the porosity or mass density. It can consistently operate at a low pressure loss.
- The coated filter material is a strong and soft fibrous structure with sufficient mechanical strength. It has descaling properties and reduces the cleaning force. Under low and stable pressure loss conditions, it can be used for a long time and extend the service life of the filter bags.
- Low pressure, high flow rate, continuous operation. Traditional deep filtration filter material.
- The dust removal bags are easy to clean and have a long service life.
Overview
Dust collector filter bags are a highly efficient type of dust removal filter material. They are made from polyester short fibers or long fibers as raw materials. Their service life is generally 4 to 6 times that of glass fiber fabrics. They feature good air permeability, high dust removal efficiency, easy to clean, and have certain resistance to acids, alkalis, and heat. During the weaving process, multi-directional pile is adopted, which increases the fabric thickness and makes it elastic. The dust removal effect is extremely good, with a dust removal rate of up to 99.999%.
Operating principle:
The filter bag is the core component of the operation of a bag-type dust collector. It is usually in a cylindrical shape and is vertically suspended in the dust collector. The dusty gas enters the dust collector through the inlet and is guided by the deflector plate in the dust hopper, causing some large particles of dust to be separated by the inertial force and directly fall into the dust hopper. The dusty gas then enters the filter bag filtration area of the box. The vast majority of the dust is captured on the outer surface of the filter bag, while the clean gas passes through the filter material and enters the interior of the filter bag. The purified gas then enters the upper box through the filter bag opening and is finally discharged through the outlet. The cage frame inside the filter bag is used to support the filter bag, preventing it from collapsing. At the same time, it helps to remove the dust cake and redistribute it.
Product category:
- 1.According to the shape of the cross-section of the dust removal filter bags, they are classified as: flat-shaped bags (trapezoidal and flat-shaped) and circular-shaped bags (cylindrical).
- 2.It is classified according to the air intake and exhaust methods as follows: bottom intake and top exhaust type, top intake and bottom exhaust type, and direct flow type (applicable only to plate-shaped flat bags).
- 3.According to the filtering method of the dust removal filter bags, they can be classified into: external filtration type and internal filtration type.
- 4.According to the temperature tolerance of the dust removal filter bags, they are classified as: high-temperature type, medium-temperature type, and normal-temperature type.
- Low-temperature type, suitable for use in bag-type dust collectors in areas with localized dust emissions such as raw material mills, cement mills, and top/bottom of storage facilities. However, when used in conditions with high moisture content, it is necessary to apply oil-repellent and waterproof treatment agents to the surface for surface treatment.
- For constant and high-temperature types, they are suitable for bag-type dust collectors used in the tail sections of cement rotary kilns, rotary kilns, coolers, and dryers for handling high-temperature exhaust gases. However, when used under high-temperature and high-humidity conditions, it is necessary to apply oil-repellent and waterproof treatment agents to the surface for surface treatment.
Applied range:
It is widely applied in: woodworking manufacturing, mechanical processing (such as welding, grinding, polishing, etc. for dust removal), spray painting workshops, metallurgical industry, casting industry, chemical industry, food processing, paper industry, etc. for dust treatment.

Central Dust Collection System
- High-efficiency filtration, ultra-high-efficiency filtration efficiency, for powders with an average particle size of 0.5 micrometers, the filtration efficiency is as high as 99.99%.
- The cleaning effect is excellent. The dust collector is installed in a modular manner, which makes the construction convenient and simple, and it is also easy to clean the filter bags.
- The footprint is small. It uses a dedicated pulse-shaped pleated filter cartridge, with a compact structure that saves floor space.
- Installation is convenient. The filter cartridge is designed in an integrated manner, with excellent sealing performance, making it easy to install and replace.
- The operation and maintenance are simple. Users can choose to use the funnel-type bag filter or the cabinet-type bag filter according to the specific situation.
Pulse Dust Collector
- The multi-chamber stop-air pulse jet cleaning technology is adopted, which overcomes the shortcomings of conventional pulse dust collectors and multi-chamber reverse-blowing dust collectors. It has strong cleaning ability, high dust removal efficiency, low emission concentration, low leakage rate, low energy consumption, low steel consumption, small floor area, stable and reliable operation, and good economic benefits. It is suitable for the purification of dust-containing gases and the recovery of materials in industries such as metallurgy, building materials, cement, machinery, chemical engineering, power, and light industry.
- Due to the use of staged air-stop pulse blowing for cleaning, a single blowing operation can achieve the goal of thorough cleaning. Therefore, the cleaning cycle is prolonged, reducing the cleaning energy consumption. The air consumption can be significantly reduced. At the same time, the fatigue degree of the filter bags and the pulse valves is also correspondingly decreased, thereby doubling the lifespan of the filter bags and valve plates.
- The bag replacement during maintenance can be carried out in separate chambers while the system's fan is not running and the system is operating normally. The bag openings are equipped with elastic expansion rings, ensuring good sealing performance and reliability. The filter bag ribs are in a multi-angled shape, which reduces the friction between the bag and the ribs, prolonging the bag's lifespan and facilitating bag removal.
- By using the top bag extraction method, during bag replacement, after removing the framework, the dirty bag is placed in the lower ash hopper of the box and then retrieved through the manhole, which improves the operational conditions for bag replacement.
- The box body is designed with an airtight structure, ensuring excellent sealing performance. The inspection door is made of high-quality sealing materials. During the manufacturing process, coal oil is used for leak detection, resulting in a very low air leakage rate.
- The inlet and outlet air ducts are arranged closely together, resulting in low air resistance.
