Selecting the dust bag in four steps

Select the dust bag and dust will go through the following four steps and hope that you can choose to suit your dusting products. 1 , First understand the flue gas temperature to be addressed: bag house filter bag as a core member . The selected filter can not adapt to the flue gas temperature is very important. Such as filter normal temperature flue gas temperature exceeds too much , due to high temperature filter material cost increase caused by higher investment in equipment . Such as filter normal temperature lower than the temperature of the flue gas , it may cause burn bag , causing great economic losses . So how do you choose by the flue gas temperature filter it ? Temperature filter press is divided into three parts: The following room temperature filter 130 ℃, the temperature of the filter 130 ~ 180 ℃, high temperature filter 180 ~ 280 ℃. Know the flue gas temperature and the temperature of the filter is not able to filter out the election . 2, The second step of the flue gas composition to know: This includes dust content, specific gravity, particle size, can be addictive, the flue gas moisture content and other parameters. By understanding these decisions precipitator cleaning method, post-processing method and media filtration velocity. A large amount of dust, dust and more sticky and light conditions generally chosen pulse jet bag filter, filtration velocity control in most of 1.2m / min or more, a few conditions 1m / min or less. Other circumstances may be, you can use the high-pressure cleaning type dust collector and cyclone. The media treated the way to have a microporous film, water and oil proof, anti-static (accession weaving conductive yarn) easy treatment, as the case may be. 3. The third step is to understand the amount of flue gas to be processed: Processing amount of wind precipitator is usually coupled with system leakage factor (10% to 15%) for the amount of wind conditions. Know precipitator air volume, filtration velocity can pass the formula: S = Q / 60V gave a total filtration area. Where S: total filtration area Q: System processing air volume V: filtration velocity 4,  As to the form of filter structure and layout, the bag size, quantity, pulse valve, the number of manufacturers are dust engineering division type thing, you just press your income above the effect of dust on the parameters and requirements for acceptance it.
