During the process of using the dust bag, its dust holding capacity will directly affect the resistance of the filter material and the cleaning cycle. In order to prevent frequent cleaning, the product effectively prolongs the life of the filter bag, usually requiring the filter dust content. Bigger. The dust holding capacity is related to the porosity of the filter material and the air permeability of the pulse dust collector. The felt filter material has a larger dust holding capacity than the fabric filter material.
Dust bags from the composition of the dust layer, after cleaning, the dust layer will be damaged, so that the power of the product will be reduced, thick filter material, dust can also save part of the dust in the filter to prevent Excessive cleaning. More than half of the 1200 kinds of products with quick-opening multi-bag filters have now achieved large-scale industrial production of separate filters, and the production capacity of China’s fast-opening multi-bag filters will greatly improve.
Dust bag is mainly used to separate dust from flue gas. Bag filter is also called filter duster. It is a kind of dry high-efficiency dust catcher. It is a bag filter element made of fiber braid to capture. Dust removal device for solid particles in dusty gas. The principle of action is that the dust particles are intercepted by the collision of the fibers with the inertial force of the filter cloth fibers.
Dust bags In pulse and air box type pulse dust collectors, dust is attached to the outer surface of the filter bag. When the dust-containing gas passes through the dust collector, dust will be trapped on the outer surface of the filter bag. It is clean. The gas enters the interior of the filter bag through the filter material. The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing, and it helps to remove and redistribute the dust cake.
The fabric and design of the dust bag should strive for efficient filtration, easy removal of dust, and durability. The selection of dust bag is very important. It directly affects the dust removal effect of the dust collector. The dust bag is selected from the following aspects: gas temperature, humidity and chemical properties, particle size, dust concentration, filtration speed, clearance Dust and other factors.
