Background

The bin top dust remover is a single dust removing device with an automatic dust removing structure, is widely used in industrial and mining enterprises such as cement, mineral powder, mining, metallurgy, building materials, machinery, chemical engineering, grain processing and the like, and is used for filtering fine and non-fibrous dry dust in gas or recycling dry powder in a process flow.

The dust-containing gas enters the box body of the dust collector from the air inlet, and fine dust particles are blocked on the outer wall of the cloth bag due to the multiple effects of the cloth bag. The purified gas is discharged through the air outlet of the box body on the cloth bag. With the increase of the service time, the dust adsorbed on the surface of the cloth bag increases, the air permeability of the cloth bag is weakened, and the resistance of the dust remover is increased continuously. In order to ensure that the resistance of the dust remover is controlled within a limited range, a pulse controller sends out signals, and electromagnetic pulse valves are opened sequentially, so that compressed air in an air bag is sprayed to a corresponding venturi tube (called primary air) through each spray hole of a spraying pipe, and ambient air (called secondary air) which is several times of the primary air is induced to enter a filter cylinder when high-speed airflow passes through the venturi tube, so that the cloth bags are expanded rapidly, and the cloth bags are contracted rapidly due to the fact that the impact action of reverse pulse airflow disappears rapidly, so that dust deposited on the outer walls of the cloth bags is removed, and fallen dust enters an ash storehouse.
