As an important part of the filtration system, dust filter bags are widely used in various industrial fields. Its main function is to filter and collect dust generated in the production process, reduce pollution emissions, protect employee health, and reduce environmental impact. For different industrial fields, the selection and use of dust filter bags are also different. This article will analyze the specific applications of sacos de filtro de poeira in industrial fields such as electricity, steel, chemicals, cement, and waste incineration to help companies understand suitable dust removal solutions.

 

1. Power industry: high temperature and corrosion resistant filter bags
In the power industry, especially thermal power plants, the combustion process of coal will produce a large amount of smoke and exhaust gas, which not only contains dust, but also may contain harmful components such as sulfides and nitrogen oxides. The flue gas temperature in the power industry is relatively high, generally between 150℃-300℃, so the high temperature resistance and corrosion resistance of the filter bag are very high.

 

Filter bag materials: Commonly used filter bag materials include PPS, P84, PTFE, etc., which have high temperature stability and acid and alkali corrosion resistance.

 

Filter bag characteristics: In the power industry, filter bags must also have good oxidation resistance and heat shock resistance to adapt to the fluctuations of boiler flue gas.

 

Use effect: The optimized filter bags can not only effectively capture tiny dust particles, but also help reduce the emission of harmful substances in the flue gas and achieve environmental protection standards.

 

2. Steel industry: wear-resistant filter bags
The flue gas generated during the steel smelting process has a large dust content and coarse particles, and some dust particles have high temperature characteristics, which are easy to wear equipment. Therefore, the steel industry has high requirements for the wear resistance and high temperature resistance of dust removal filter bags.

 

Filter bag materials: The steel industry usually uses glass fiber filter bags or composite filter bag materials, such as PTFE coated filter bags and glass fiber coated P84 filter bags.

 

Filter bag characteristics: The filter bags used in high temperature areas of the steel industry must not only be resistant to high temperatures, but also have high tensile strength and good wear resistance to cope with highly abrasive dust.

 

Use effect: Suitable filter bag materials can effectively extend the service life of the filter bag, reduce the frequency of replacement, and greatly improve the dust capture efficiency and reduce secondary pollution.

3. Chemical Industry: Corrosion-Resistant Filter Bags
During the chemical production process, a variety of corrosive gases and dusts are generated, such as chlorides, sulfides, acidic dusts, etc., so strict requirements are placed on the corrosion resistance of dust filter bags. At the same time, the dust particle size and composition in the chemical industry vary greatly, so the material selection and filtration efficiency of the filter bag also need to be accurately matched according to the working conditions.

 

Filter bag materials: PTFE, PPS, P84 and other highly corrosion-resistant materials are commonly used in the chemical industry. These materials have excellent acid and alkali resistance and can maintain stability in strong acid and alkali environments.

 

Filter bag features: High temperature resistance and chemical corrosion resistance are the basic requirements for filter bags in the chemical industry. The surface of the filter bag also needs to be treated to reduce the adsorption and electrostatic accumulation of dust.

 

Use effect: Highly corrosion-resistant filter bags can be used in acid and alkali environments for a long time to ensure dust removal efficiency while reducing the company's filter bag replacement and maintenance costs.

 

4. Cement industry: high temperature resistant filter bags
The production process of the cement industry needs to go through multiple high temperature links, especially the large amount of high temperature flue gas generated at the head and tail of the kiln has high dust content. The dust also contains certain components such as silica and calcification, which poses a challenge to the high temperature resistance and acid and alkali corrosion resistance of the filter bag.

 

Filter bag materials: Glass fiber filter bags or coated filter bags are commonly used in the cement industry, such as P84 coated filter bags, which can resist the influence of high temperature environment during cement production.

 

Filter bag features: The filter bag material should be resistant to high temperature and acid, especially in the case of large production fluctuations, it can adapt to instantaneous temperature changes. At the same time, the filter bag needs to have good cleaning performance to prevent dust accumulation and clogging.

 

Use effect: The use of high temperature resistant filter bags can effectively filter high temperature dust, reduce equipment loss, improve the overall stability of the dust removal system, and meet the environmental protection emission requirements of the cement industry.

 

5. Waste incineration industry: acid and alkali resistant filter bags
The flue gas produced during the waste incineration process has complex components, which may contain acidic gases, heavy metals, dioxins and other harmful substances, which puts forward multiple requirements for filter bag materials to be acid, alkali and oxidation resistant. The incineration flue gas has high temperature and strong corrosiveness, which requires the filter bag to have super corrosion resistance and filtration capacity.

 

Filter bag materials: PTFE, P84, composite glass fiber filter bags, etc. are commonly used in waste incineration. These materials have good acid and alkali resistance and high temperature oxidation resistance.

 

Filter bag features: The surface of the filter bag usually needs to be coated to enhance corrosion resistance and anti-stickiness, thereby preventing harmful substances from attaching. For difficult-to-degrade substances such as dioxins, the filter bag needs to have a higher microporous structure to achieve deep filtration.

 

Use effect: High-efficiency dust removal filter bags can effectively capture toxic substances in incineration flue gas, reduce pollutant emissions, and ensure environmental protection standards during the incineration process.

 

6. Other fields: Flexible application of general filter bags
In addition to the above-mentioned major industries, dust filter bags have also been widely used in papermaking, pharmaceuticals, food processing and other fields. Although the dust composition and emission requirements of these industries are different, they all require efficient and stable dust removal and filtration solutions.

 

Filter bag materials: General filter bags are mostly made of polyester fiber, polypropylene, nylon and other materials to adapt to lower temperatures and general dust filtration needs.

Filter bag characteristics: In these industries, filter bags are mainly used to filter tiny dust particles to ensure a clean production environment. Therefore, filter bag materials usually have good air permeability and moisture resistance.

Use effect: General filter bags can effectively control dust emissions, reduce air pollution, and at the same time improve the cleanliness of the workshop environment, which helps to improve product quality and employee health.
