How to prevent dusting filter bag from falling off

When the high-temperature dust bag is removed, five to eight times the secondary air enters the dust bag when the high-speed air flow passes through the dust bag cage. The material of the dust bag cage is mainly determined according to the application place, which leads to the rapid expansion of the cloth bag immediately. In a high temperature dust bag, the deformation of a flat bag is greater than that of a round bag. Therefore, when the blow bag shrinks, the collision effect with the dust skeleton is stronger and more dust leaks are produced. In addition, dust that separates from the flat bag migrates into the adjacent cloth bag more severely than the round bag.

First of all, the length of the dust bag, in the treatment of smoke gas, filtration speed and the diameter of the dust bag is the same, increasing the length of the dust bag can reduce the number of dust bags, thereby reducing the area, reduce the electromagnetic valve, pulse valve, blow pipe and other parts of the dust system, save investment, can also shorten the dust cycle. When the dust bag is online, the longer the dust bag is, the more likely it is to return to the cloth bag. If the dust removal is offline, the longer the dust bag is, the longer the pause time after the dust removal is, and the slower the filtration recovery in the dust removal chamber is. In a bag filter, the soot adheres to the outer surface of the bag. When the dust gas passes through the dust collector, the dust is blocked on the outer surface of the filter bag, and the clean gas will enter the filter bag through the filter material. The cage in the high-temperature dust bag is used to support the filter bag, prevent the filter bag from collapsing, and facilitate the removal and redistribution of the filter cake. High temperature dust bag fabric and design should be efficient filtration, easy dust removal, durable. The selection of dust bag is very important, which directly affects the effect of dust removal.

Although the size of high-temperature resistant cloth bag is slightly smaller, it can also be used, but after the adsorption of large dust, it will paste the bag for a period of time. The key of dust removal is to correctly select the high temperature resistant cloth bag suitable for the corresponding dust temperature. If the temperature is too high, the selected high temperature resistant cloth bag exceeds the normal use temperature, the dust removal high temperature cloth bag will shorten the service life, serious time is short. Therefore, the calculation of the dust collector must be determined when selecting the high temperature filter bag.
