Hebei Feixiang Environmental Protection Equipment Co., Ltd. reminds new and old customers to pay attention to traffic issues when traveling in foggy weather.
The process air used in the production and manufacturing process of cigarette factories, such as leaf cutting, impurity removal, wire drying, air selection, and rolling, as well as the environmental dust removal air used to treat dust on the production site, need to be filtered by dust removal equipment before being discharged. At the same time, the dust collected by the dust collector is then compacted by a pressure rod machine and transported for treatment. Therefore, the dust removal system is equipment in cigarette factories.
Bag filter is widely used in the tobacco industry due to its simple performance, easy management and cleaning, and other advantages. Bag filter dust collector (also known as filter dust collector), in simple terms, uses filter bags to intercept and filter solid dust in the air to purify the air.
The key component of a bag filter is the filter bag. The performance of the filter bag directly affects the dust removal effect, so when purchasing a dust collector, the performance of the filter bag should be considered, such as mesh permeability, heat resistance, mechanical strength, etc. Its mechanism of action is that the dust in the air undergoes chaotic Brownian motion due to continuous collisions between molecules. When passing through the filter fibers, the gaps between the fibers are smaller than the free path of gas molecule Brownian motion, and the dust particles cannot be adsorbed on the filter bag through the ventilation holes. The purified air is directly discharged through the exhaust holes to achieve separation effect. The working process is influenced by various factors such as filter cloth preparation method, fiber pore density, dust particle size, and cleaning method.
Dust containing gas is evenly distributed in the filter bag through a gas distribution device. Under the action of inertial force, the dust containing gas collides with the fibers of the filter bag, and solid particulate matter is adsorbed on the filter cloth due to the collision. The purified air is discharged through the filter holes. When the dust adsorbed on the filter bag reaches its thickness, the solenoid valve opens, and air is blown back into the filter bag from the outlet, opposite to the direction of the dusty gas flow. Under the action of gravity, the dust adsorbed on the outer surface of the filter bag is scattered into the ash hopper below, which can be centrally treated and cleaned in the later stage.
