The dust removal effect of the pulse bag filter is not obvious and related to many factors, but it is generally a relatively phenomenon. The pulse bag filter produced by our company can almost achieve the purpose of dust removal, and the dust removal power can exceed the dust concentration stipulated in our country. Emission standards, our company, as an entity manufacturer of pulse bag filter, is committed to Chilean industrial dust, protects the atmospheric environment, and creates value for customers.

The reasons why the dust removal effect is not obvious are as follows:
The pulse bag filter is a dust removal device. Once it is found that the outlet of the exhaust pipe behind the filter is dusty and the dust emission is large, the reasons can be found from the following aspects:
Air box pulse bag filter
1. The newly installed clean filter bag has large pores, and the dust passing rate is high when it is first used, and it has not reached a good filtering state, and the dust emission is large. With the progress of filtration, dust accumulates on the outer surface of the filter bag to form a dust layer, which makes the pores on the outer surface of the filter bag smaller, and the dust removal efficiency increases. Therefore, it is more accurate to measure the dust removal power of the pulse bag filter after 1 month of continuous use.
2. Check whether the filter bag is installed correctly. The general pulse bag type dust collector relies on the elastic expansion ring sewn on the mouth of the filter bag to embed the filter bag into the hole of the flower plate, and the dust chamber of the middle box is strictly distinguished from the clean air chamber of the upper box through the flower plate. If the elastic expansion ring at the mouth of the filter bag fails to close with the hole of the flower plate, there is a gap, which will cause the dust-laden airflow to directly enter the clean air chamber, and the outlet of the exhaust pipe will emit dust. You can check the installation of the filter bag mouth one by one, and find that the gap should be compressed and sealed. In the installation process of the pulse bag filter, the installation quality of the filter bag is one of the key points of supervision and inspection. The ironmaking plant has improved and optimized the device of the filter bag: a ferrule is welded above each flower plate hole, the height of the ferrule is 30mm and it is concentric with the flower plate hole, and the single-layer elastic expansion bag sewn on the mouth of the filter bag will be expanded. The ring is installed close to the inner wall of the ferrule, which not only ensures that the installation of the filter bag is highly flat and sealed, but also makes the installation and disassembly of the filter bag simpler.
