Problems solved by technology

[0002] At present, the known methods of purifying dust-laden gas through filter bags are usually inner filter type and outer filter type and are used alone, the filter area is limited, the equipment occupies a large area, and the cost is high
In order to improve the efficiency of filtration and purification, most of them adopt the method of increasing the filter area of ​​the filter bag. Generally, there are two methods: one is to increase the diameter of the filter bag; the other is to lengthen the length of the filter bag. The area is large and the cost is high. However, with the increase in the practical requirements of the filter bag, its temperature resistance and anti-degeneration are more and more important
