Customized cast aluminum three ear anti-static material dust filter cartridge

The dust removal filter cartridge is the core filtering element of the filter cartridge dust collector, which is folded from high-performance materials such as polyester fibers and has a large filtering area. Here is a detailed introduction for you:

structural material

• filter mediaVarious materials are commonly used, with polyester fiber as the base fabric. Some products are covered with polytetrafluoroethylene (PTFE) microporous film on the surface, while others may add conductive fibers; There are also types that use wood pulp fiber paper, which are biodegradable and more environmentally friendly. Polyester fibers ensure the strength and stability of the filter material, while PTFE membranes have characteristics such as chemical stability, easy dust cleaning, good breathability, and high temperature resistance. Conductive fibers can enhance anti-static performance.

• end coverGenerally, it is made by stamping rust proof steel plates with a thickness of 8mm or more, and high-strength ABS plastic may also be used. The bonding between the end cap and the filter material is made of special polyurethane foam adhesive, which is tightly connected without gaps and can withstand high pressure and airflow impact.

• skeletonThe internal and external support protection skeleton is often made of high-strength, corrosion-resistant electroplated diamond mesh or stainless steel material with a diameter of 5mm or more. It has a high porosity and can provide strong support for the filter cartridge, ensuring uniform airflow through the filter material.

• sealing material: Generally, the fluororubber soft sealing rubber ring with a width of about 1.1 cm can be used, or the sealed closed cell elastic neoprene rubber can be used, which has good corrosion resistance and aging resistance and can avoid dust leakage.

working principle

In a filter cartridge dust collector, the exhaust gas first enters the dust collector, and when it passes through the surface of the filter cartridge, the particulate matter is trapped on the outer surface of the filter cartridge, while the purified gas is discharged through the inside of the filter cartridge. As the filtration progresses, dust gradually accumulates on the surface of the filter cartridge, leading to an increase in resistance. When the resistance reaches the set value, the pulse cleaning system is activated, and compressed air is instantly sprayed into the interior of the filter cartridge, causing high-frequency vibration of the filter cartridge. The dust adhering to the surface of the filter cartridge is shaken into the ash hopper, thereby achieving the regeneration of the filter cartridge. After the dust cleaning process is completed, the dust collector returns to its normal filtering state.

Performance Characteristics

• High filtration accuracyThe filtration accuracy of different types of filter cartridges varies, generally reaching around 0.3-5 μ m. For dust particles with corresponding particle sizes and above, the filtration efficiency can reach over 99.9%. If PTFE coated filter material is used, the filtration efficiency can be even higher, effectively intercepting various small dust particles.

• Strong chemical stabilityPolyester fiber and PTFE membrane materials can resist the erosion of chemical substances such as acid and alkali, and maintain stable filtration performance in environments with chemical corrosion risks.

Application scenarios

Commonly used in filter cartridge dust collectors, which are widely used in industries such as woodworking, metallurgy, chemical, food, and medicine to remove dust and particulate matter generated in industrial production processes.

• PU sealing installationFilter cartridges are generally installed vertically at the bottom, suitable for small diameter filter cartridges and small equipment. They can replace cloth bags to increase the filtration area, but are generally not suitable for working conditions with high dust volume.

• Three ear flange installationThe filter cartridge is generally installed vertically at the bottom, with a flower plate with screws, which are locked with nuts and washers. The flange material can be cast aluminum or stainless steel.

• Installation of circular flangeThe operation can be carried out according to the installation method of the rubber pad.

• Side mounted chuck installationIt is a side installation method, installed through side opening doors, sliding rods, etc.

• Vertical installationFilter cartridges are arranged from top to bottom and are commonly used in standalone equipment. During pulse cleaning, dust is prone to fall and settle into the ash hopper, resulting in good cleaning effect and suitable for working conditions with slightly higher dust concentration.

• Tilted installationThe filter cartridges are stacked on top of each other, with a compact structure and small footprint, making it easy to replace the filter cartridges. However, the dust that falls off the upper filter cartridge during dust cleaning will settle on the lower filter cartridge, making it difficult to remove. This installation method is suitable for non sticky, low concentration, and coarse dust removal in small and medium-sized dust removal systems, as well as for the renovation of some old-fashioned bag filters. For high air volume and low concentration working conditions, such as welding fumes, the use effect is also good.

• Horizontal installationThe dust on the upper part of the lower filter cartridge is more difficult to remove.
