Warehouse top bag dust collector
The pulse warehouse top dust collector is a special equipment for high-efficiency purification specially designed for the working conditions of foundries, thermal power plants ash warehouses, and slag warehouses. It adopts advanced dust cleaning technology, has large gas processing capacity, good purification effect, and simple structure, Reliable work, small maintenance and other advantages. In the structural design has taken into account the characteristics of its layout, due to the good sealing of the product, it can be arranged in the open air.
Working principle
Dust-containing gas enters the dust collector box from the air inlet, and fine dust particles are blocked on the outer wall of the bag due to the obstruction of dust air by the bag. The purified gas is discharged through the air outlet of the box on the cloth bag. With the increase of use time, the dust adsorbed on the surface of the bag increases, the permeability of the bag weakens, and the resistance of the dust collector increases. In order to ensure that the resistance of the dust collector is controlled within a limited range, the pulse controller sends a signal to open the electromagnetic pulse valve in sequence, so that the compressed air in the air bag is injected from each nozzle hole of the nozzle to the corresponding venturi), and when the high-speed airflow passes through the venturi, the surrounding air (called secondary air) several times of the primary air is induced to enter the bag, causing rapid expansion between the bag, due to the impact of the bag, the bag shrinks sharply, so that the dust on the outer wall of the bag is removed. Falling dust enters the ash silo.
Since the cleaning is carried out to several groups of filter cartridges in turn, and does not cut off the dust-containing air that needs to be treated, the processing capacity of the dust collector remains unchanged during the cleaning process.
blowing system
The composition of the injection system, pulse valve A is connected to the compressed air bag, B is connected to the injection pipe, pulse valve back pressure control valve, control action is instructed by the controller. When there is no signal output from the control instrument, the movable iron core of the control valve seals the exhaust port and the pulse valve is closed. When the control instrument sends out a signal, the control valve communicates the pulse back pressure chamber with the atmosphere, the pulse valve opens, and the compressed air isThe bag is sprayed into the venturi through the pulse valve through the small hole of the spray pipe, resulting in instantaneous positive pressure in the filter bag to realize dust removal.
