Application Introduction:
Application of dust removal filter bag in chemical industry
The chemical industry is one of the important pillar industries in China, but it is also an industry with high pollution, high energy consumption and high risk. In recent years, with the continuous improvement of the national requirements for environmental protection, the chemical industry has begun to pay attention to environmental protection. As an environmental protection dust removal equipment, dust removal filter bag has been more and more widely used in the chemical industry.
1、 Principle and classification of dust removal filter bag
Dust removal filter bag is a kind of filtering equipment. Its principle is to block dust particles on the surface of the filter bag by using the filtering effect of fiber materials, so as to achieve the purpose of purifying gas. The dust removal filter bag has high filtration accuracy and can filter out small dust particles, which is very good for PM2.5, PM10 and other particles.
There are many ways to classify the dust removal filter bag, which can be divided into natural fiber, synthetic fiber, composite fiber, etc. according to the material; According to the filtration methods, it can be divided into surface filtration and deep filtration; According to the structure, it can be divided into cylindrical, flat, conical, etc. In the chemical industry, commonly used dust removal filter bags include polyester fiber, acrylic fiber, polytetrafluoroethylene and other materials, which have the characteristics of corrosion resistance, high temperature resistance and high strength.
2、 Application of dust removal filter bag in chemical industry
Application in chemical reaction process
In chemical production, many chemical reactions will produce a large number of dust particles, such as caustic soda, synthetic ammonia, chemical fertilizer and other production processes will produce a large number of smoke and gas. In these production processes, the dust removal filter bag can be installed at the exhaust port of the reactor or the outlet of the fan to filter the gas and reduce the emission of dust particles. At the same time, the dust removal filter bag can also recover useful substances and improve the recovery rate of products.
Application in drying process
Drying is one of the common processes in chemical production, but a large amount of dust and gas will be produced in the drying process. In order to reduce the emission of dust and gas, a dust removal filter bag can be installed at the exhaust port of the drying equipment to filter the gas. This can not only reduce the emission of dust and gas, but also improve the quality and yield of products.
Application in crushing and mixing process
In chemical production, crushing and mixing is one of the common processes, but it will also produce a lot of dust. In order to reduce the generation and emission of dust, dust removal filter bags can be installed on the crushing and mixing equipment to filter the generated dust. This can effectively reduce the generation and emission of dust, protect the environment and protect the health of workers.
Application in conveying process
In chemical production, dust is also easy to be generated during the transportation of various materials. For example, dust will be generated in the conveying pipeline and pneumatic conveying equipment of powder materials. Dust removal filter bags are installed at the exhaust port of these equipment to filter the gas and reduce the emission of dust. At the same time, the dust removal filter bag can also play the role of recycling useful substances and improve the utilization rate of products.
In short, dust removal filter bags are widely used in the chemical industry, which can not only reduce dust emissions and protect the environment, but also improve the quality and yield of products. In the future, with the continuous improvement of environmental protection requirements and the development of technology, the application of dust removal filter bags in the chemical industry will be more extensive and important.
