The pulse single-machine dust collector can be widely used in dust collection systems for dust and smoke in asphalt mixing plant crushers, mills, dryers, kilns, etc. The material of the dust collector filter bag is generally polyester needle felt, which allows The continuous use temperature is ℃. If the filter bag is made of Metas high-temperature needle felt, the allowable use temperature can reach ℃.
The pulse single-machine dust collector can be combined with a variety of dust collectors of different specifications according to the solenoid valves of different specifications. This series of dust collectors can be operated under negative pressure or positive pressure without any change in the body structure. The dust collection efficiency reaches more than .% of the purified gas content. Dust concentration The working principle of the pulse single-machine dust collector: When the dust-containing gas enters the dust collector from the air inlet, it first hits the inclined plate and baffle in the middle of the air inlet and outlet, and then the airflow turns to flow into the ash hopper. At the same time, the airflow speed slows down due to inertia. Medium and coarse particle dust flows directly into the ash hopper. The airflow that enters the ash hopper for pre-dust collection then turns upward and passes through the filter bag with a metal skeleton inside. The dust is collected on the outer surface of the filter bag. The purified gas enters the upper clean room of the filter bag chamber and collects at the air outlet to be discharged. During the purification process of dust gas through the filter bag, as time goes by, more and more dust accumulates on the filter bag, increasing the resistance of the filter bag, causing the treatment air volume to gradually decrease. For normal operation, the resistance must be controlled within a certain range (mm water column) When the filter bag must be cleaned, the pulse controller sequentially triggers the opening of each control valve. The compressed air in the pulse valve air bag is sprayed through the venturi tube from each hole in the blow pipe into the corresponding filter bag. The filter bag expands sharply in an instant, causing the dust to accumulate. The dust attached to the surface of the filter bag falls off and the filter bag is regenerated. The cleaned dust falls into the ash hopper and is discharged from the machine through the ash discharge system. As a result, the dust accumulated on the filter bag is periodically pulse-injected and cleaned, so that the purified gas can pass normally to ensure the operation of the dust removal system.
