The working principle of the Miteqi vacuum cleaner’s pulse reverse-blow system.
Release time:2022-11-17
In the Metengqi vacuum cleaner, dust-laden air enters the dust collector housing through the inlet port. Fine particulate matter is retained on the outer surface of the filter cartridges due to a variety of effects exerted by the filter elements. The purified air then exits through the outlet port located in the upper part of the filter cartridge housing. As usage time increases, more and more dust accumulates on the surface of the filter cartridges, reducing their permeability and causing the resistance of the dust collector to rise continuously. To ensure that the dust collector's resistance remains within the specified range, the pulse control unit sends signals that sequentially open the electromagnetic pulse valves, allowing compressed air from the air tank to be ejected through the nozzles of the blow pipes into the corresponding Venturi tubes (referred to as primary air). As the airflow passes through the Venturi tubes, it induces several times its volume of surrounding air (referred to as secondary air) into the filter cartridges, causing them to expand rapidly. Once the reverse pulse airflow’s impact effect quickly subsides, the filter cartridges contract sharply, thereby dislodging the dust accumulated on their outer surfaces. The fallen dust then settles into the ash hopper.
The dust collector’s processing capacity remains unchanged.
Brief Overview of the Metengqi Vacuum Cleaner’s Pulse Blowing System:
The pulse blowing system consists of a pulse valve. End A of the pulse valve is connected to the compressed air tank, while end B is connected to the blow pipe. The pulse valve features a back-pressure-controlled valve, and its operation is commanded by the control unit. When the control unit does not output any signal, the moving iron core of the control valve seals the exhaust port, keeping the pulse valve closed. However, when the control unit sends a signal, the back-pressure chamber of the control valve communicates with the atmosphere, opening the pulse valve. Compressed air from the tank then flows through the pulse valve and out through the small holes in the blow pipe, entering the Venturi tubes and creating an instantaneous positive pressure inside the filter bags, thus achieving dust removal.

The dust-laden gas from the Metengqi vacuum cleaner enters the dust collector housing through the air inlet. Fine particulate matter is retained on the outer surface of the filter cartridges due to a variety of effects exerted by the cartridges themselves. The purified gas then exits through the outlet port located in the upper part of the housing, passing through the filter cartridges. As usage time increases, more and more dust accumulates on the surface of the filter cartridges, reducing their permeability and causing the resistance of the dust collector to rise continuously. To ensure that the collector’s resistance remains within the specified range, the pulse control unit sends signals that sequentially open the electromagnetic pulse valves, allowing compressed air stored in the air bags to be ejected through the nozzles of the blow pipes into the corresponding Venturi tubes (referred to as primary air). As the airflow adjusts while passing through the Venturi tubes, it induces several times the volume of surrounding air—known as secondary air—into the filter cartridges. This causes the filter cartridges to expand rapidly. However, the reverse pulse airflow quickly dissipates its impact, causing the filter cartridges to contract sharply again. In this way, the dust adhering to the outer surfaces of the filter cartridges is dislodged and falls into the dust collection bin.
The dust collector’s processing capacity remains unchanged.
Overview of the Miteqi Vacuum Cleaner Blowing System:
The composition of the blow-cleaning system is as follows: The A end of the pulse valve is connected to the compressed air reservoir, while the B end is connected to the blowpipe. The pulse valve features a back-pressure control valve, and its operational actions are commanded by the control unit. When the control unit does not output any signal, the moving iron core of the control valve seals the exhaust port, keeping the pulse valve in the closed state. However, when the control unit sends a signal, the back-pressure chamber of the control valve communicates with the atmosphere, causing the pulse valve to open. Compressed air then flows from the reservoir, through the pulse valve and into the small holes of the blowpipe, and finally into the Venturi tube, generating an instantaneous positive pressure inside the filter bags and thus achieving dust removal.
