参考资料下载 The main factors affecting the dust bag
The dust bag is the main dust collector accessory of the bag dust collector. It is also one of the main accessories of the bag dust collector. The dust bag can isolate harmful gases and protect the environment and maintain the health of employees. However, during the use of the dust bag , there are Many factors have an important impact on the service life of the dust bag , and the most important factor affecting the service life of the dust bag is the processing of the flue gas. The following is the effect of the professional and technical staff of Wo Nuo Company on the service life of the dust bag . Give a detailed explanation:
(1) High temperature of the flue gas. Bag dust collectors are mainly used for dust removal in industrial boilers, fluidized bed boilers, kiln and coal-fired power station boilers. The temperature of this type of flue gas is often relatively high, and the temperature when the gas enters the dust collector is generally about 100 ° C to 300 ° C. Therefore, the performance of ordinary chemical fibers at this temperature will be affected, so the filter material of the bag filter must use high temperature and corrosion resistant fiber materials.
(2) Corrosion of acid gas. When burning high-sulfur coal or flue gas without desulfurization treatment, the concentration of sulfur oxides and nitrogen oxides in it will be very high. Except for the dusting bag of FT filter material, other chemical synthetic fiber materials will be damaged by corrosion. In this way, the life of the dust bag will be shortened, and the anti-corrosion needs to be satisfied when selecting the dust bag .
(3) Oxidation of smoke. The flue gas has a certain oxidation effect on the dust bag . Because the oxygen in the air accounts for 21%, and the temperature of the flue gas is very high, the dust bag will be harmed during work. If you want to avoid this situation, just To choose some dust-removing cloth bags with anti-oxidizing filter materials, such as dust-removing cloth bags made of P84 polyimide material, PPS high-temperature dust-removing cloth bags , flumes dust-removing cloth bags .
(4) Moisture in the flue gas. Working under high temperature conditions, when the moisture content of the dust in the flue gas exceeds 25%, the dust will cause the phenomenon of easy sticking and bag blocking. If the material's hydrolysis resistance is not high, the hydrolysis will also cause the filter material to suffer Damage, such as this case, you can use water- and oil-repellent dust bag products.
At present, our country is developing rapidly. For the health of people ’s livelihood and the worsening of the national environment, the production of Novo ’s dust bag has solved the problem of industrial pollution. The dust removal effect of the dust bag in the bag dust collector can reach 99.5%, but Different materials, the application conditions of the dust bag are different. So I hope that everyone can make reasonable use of the dust bag to make our sky bluer and let us have a healthier and cleaner tomorrow.
