Dust filter cartridge lefilter

Dust filter cartridge

The structure of the dust filter cartridge is a star-shaped filter cartridge composed of a certain length of filter material that is folded and formed by a corrugated machine, the filtering surface area is increased by 2-3 times.

Application machinery industry, metal industry, chemical industry, energy industry, medicine, electronics industry, etc.
Filter media particulate matter in the air, floating dust, etc.

Features

Increase the filter area: Compared with the traditional filter bag, the filter surface area is increased by 2-3 times of the same height.
Low pressure drop:the same air volume can get lower pressure drop.
Low emission: The air-to-cloth ratio is reduced, and lower emission requirements can be achieved.
Easy to install:The quantity of filter cartridges is less than that of filter bags, and it is shorter, which is easy and quick to install.
Simple structure:no additional keels and venturis are required.

Product features of composite fiber filter cartridge
1. Good surface filtration performance, excellent filtration efficiency can be achieved without forming a filter cake;
2. Excellent cleaning ability, very little dust on the surface of filter material;
3. During the cleaning cycle, the particles are easier to discharge, which solves the problem of the coalescence of extremely small dust between the folds and folds of the filter material, so that the air flow is reduced to the lowest level and the air flow is stable;
4. The flow rate is large, and the flow rate is increased by 30-50% compared with ordinary filter materials;
5. Long service life and smoother resistance rise.

Features of polyester fiber filter cartridge
1. Selection of filter material that is easy to clean;
2. Quasi-surface filtration design;
3. Very high wear resistance;
4. The design of easy cleaning, the filter area is designed according to different working conditions, and the cleaning of the filter cartridge is more thorough and clean;
5. High strength, good stiffness, good moisture resistance, and can be washed many times.

Working principle

Under the action of the main fan of the system, the dust-containing gas enters the air box at the bottom of the dust collector from the air inlet at the top of the dust collector for pretreatment of the dust-containing gas, and then enters each dust removal chamber of the upper box from the bottom; After the fine and low-density dust particles enter the dust filter chamber, through the combined effects of Brownian diffusion and sieving, the dust is adsorbed on the outer surface of the filter material, and the filtered clean gas enters the clean air chamber of the upper box through the filter cartridge. The exhaust pipe is collected by the fan and discharged to the air outlet.

(1) Ordinary polyester non-woven filter cartridge

It is made of polyester fiber material, and the filtration accuracy is generally above 5μm. Scope of application: filtration in powder spraying, sandblasting, pigment, wood, cement and other industries.

(2) Laminated polyester non-woven fabric

Imported PTFE-coated polyester filter material is used. The filter cartridge made of this material has a long service life, high filtration accuracy, and is easier to clean by backflushing. It can reach 1-2 years under normal working conditions. Scope of application: welding fume, shot peening Filtration in foundry, pharmacy, cement, tobacco, textile industry (prevention and control of coal ash yarn) and other industries.

(3) Anti-static polyester non-woven fabric

Anti-static, that is, anti-static aluminum film treatment, is a very thin conductive and breathable metal aluminum coating on the surface of the filter material to avoid electrostatic flashover. It is suitable for metal dust filtration and explosion-proof dust removal.

(4) Oil-proof and waterproof polyester non-woven fabric

Oil-proof, waterproof and dust-proof treatment is to cover the filter material fiber with a layer of fluororesin, so that the filter material has the functions of oil and water resistance and anti-fouling, dust is not easy to adhere, and it is easier to blow back and clean the dust. Suitable for wet or oily, dust concentration Large dust, can also be used to dry large particle size dust, the effect is better.

(5) Wood pulp fiber filter paper

Using wood pulp fiber composite filter paper, the scope of application: filtration of gas turbines, compressors, sandblasting, tobacco, fly ash, floating dust and other industries.
