Working Principles of Dust Collection Equipment Filter Bags
Dust collection equipment filter bags operate through the combined action of multiple principles to achieve efficient purification of dusty gases:1. Sieving Effect
The filter bag functions like a sieve with a specific pore size. When dusty gas passes through, dust particles larger than the pore size of the filter bag cannot penetrate and are directly intercepted on the surface of the filter bag. For example, in some wood – processing workshops, large wood chips are intercepted by sieving.
2. Inertial Impaction
When the dusty gas stream passes through the filter bag, the direction of the gas flow changes. Larger – mass dust particles, due to inertia, cannot change direction in time along with the gas flow and will collide with the fibers of the filter bag and be captured. In steel mills, during the high – temperature smelting process, large – sized dust particles are intercepted by inertial impaction when the gas passes through the filter bag.3. Interception Effect
Some dust particles slightly smaller than the pore size of the filter bag, when brought close to the filter bag fibers by the gas flow, will be directly intercepted by the fibers. It’s similar to how small objects in a narrow passage are easily blocked by obstacles beside them.4. Diffusion Effect
For extremely fine dust particles, they will perform irregular Brownian motion under the influence of the thermal motion of gas molecules, which increases the chance of contacting and being adsorbed by the filter bag fibers. In chemical production, some fine dust is captured by the filter bag through the diffusion effect.5. Electrostatic Adsorption
Some filter bag materials generate static electricity during friction with dust, or they already carry static electricity. Dust particles will be adsorbed onto the filter bag due to electrostatic attraction, enhancing the filtration effect. For example, some filter bags specially used to handle flammable dust often utilize the principle of electrostatic adsorption to improve dust removal efficiency.These principles work in concert, enabling the filter bags of dust collection equipment to effectively purify dusty gases, ensuring a clean production environment and the normal operation of equipment. -

Polyester needle felt waterproof, oil-proof and electrostatic filter bag.
Our company polyester needle filter felt selection of 1-2.5D polyester fine denier, with high strength and low elongation yarn woven reinforced base cloth, through the needle reinforcement and post-treatment technology. In addition to the characteristics of high porosity, good permeability, acid resistance and moderate alkalinity of ordinary felt filters, the product has very good wear resistance, so it is a variety of felt filters widely used. G weight from 350g/m2-800g/m2, thickness from 1mm-4mm our factory can produce. The post-treatment methods are calendering, singeing, heat setting, impregnation drying, coating and so on. It has the characteristics of stable size, easy cleaning and long service life.The surface smoothness of filter material has a great influence on the dynamic running resistance of filter material. The initial resistance of the filter material is determined by the permeability of the filter material itself, and the resistance in operation is many times larger than the initial resistance. The running resistance depends on the smoothness of the filter surface and the cleaning effect. It is generally hoped that when the filter material ensures the same filtration efficiency, the larger the air permeability, the better, that is, the lower the resistance, the better, because this can save a lot of energy. In the dust collector with air flow back blowing, when the air flow of the same pressure and the same air volume is used for dust removal, the dust removal effect of the woven fabric with high air permeability is better than that of the woven fabric with low air permeability. Therefore, in the case of ensuring the high filtration accuracy of the filter material, how to improve the permeability of the filter material and improve the surface smoothness, reduce dust adhesion, and reduce the operating resistance is the first topic that the filter material manufacturer should study. The air permeability of the surface resinized smooth finishing needled filter felt developed by our factory is more than 50% higher than that of ordinary calender finishing filter material, and the surface smoothness is more smooth than that of calender finishing.

customized dust air filter bag
Popular matching customized dust air filter bag Filtration Polyester needle felt for cement plant and power plant.
ndustrial dust filter bag is the key component of industrial dust removal equipment.
It is mainly used to capture solid particles such as dust produced in the industrial production process. Generally, it is a cylindrical bag-like fabric with a variety of materials, including polyester fiber, polypropylene, aramong and so on. The filter bag made of polyester fiber has good acid and alkaline resistance and can resist chemical erosion to a certain extent; The aramid material has high strength and high temperature resistance, which is suitable for high temperature working environment.
The working principle of the filter bag is that after the dust-containing gas enters the bag dust collector, the dust with larger particles settles first under the action of gravity, and then the gas passes through the filter bag, the dust is intercepted on the surface of the filter bag, and the clean gas is discharged. Its filtration accuracy varies depending on the material and process, and it can effectively filter micron level particles, so as to achieve the purpose of purifying the air.
