The application discloses a kind of
closed space ventilation dust removal device and dust removal method, ventilation dust removal device includes air supply fan and dust removal component, the outlet end of the air supply fan is connected with the ventilation
pipe of entering
closed space and communicates, air distribution connector is connected in ventilation
pipe end portion, the air distribution connector is equipped with the air supply
branch pipe that is communicated with dust removal component, dust removal component includes the air
amplifier that is communicated with air supply
branch pipe, and the air flow that enters air
amplifier by air supply
branch pipe generates negative pressure and carries out dust removal to the air of
closed space;Pressure regulating mechanism for guaranteeing the
gas pressure of air supply branch pipe is set on air distribution connector, the application utilizes air supply branch pipe and air
amplifier to realize using one air supply fan to simultaneously realize the ventilation of closed space and dust removal power supply, equipment
energy consumption can be reduced, and the
gas pressure in air supply branch pipe is kept using pressure regulating mechanism, to ensure the air extraction
processing efficiency of dust removal component.
