The MD series off-line dust cleaning pulse dust collector is a high-tech product with international standards in the 1990s, which is a collection of more than ten years of research and technology experience and results. It integrates the current international excellent long bag offline pulse dust removal technology and is launched to users product. It is a large-scale dust removal equipment with large air volume, good dust cleaning effect, high dust removal efficiency, reliable operation, easy maintenance and small floor space. It is widely used in dust control and material recovery in steelmaking blast furnaces in the metallurgical industry, raw material injection coal preparation and other factories, building materials industry, electric power, chemical industry, carbon black, asphalt concrete mixing, boilers, flue gas dust removal and other industries. When the dust-laden gas enters the dust collector from the air inlet, the air flow turns to flow into the ash hopper. At the same time, the air flow speed slows down. Due to the inertia, the coarse dust in the gas flows directly into the ash hopper. It plays the role of pre-dust collection. The airflow entering the ash hopper 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 to the outlet. When the air outlet is discharged and the dust-containing gas is purified through the filter bag, the dust accumulated on the filter bag is periodically pulse-injected and cleaned to allow the purified gas to pass normally and ensure the operation of the dust removal system.
