The application provides a multi-stage
cyclone structure
intelligent control aeration device, and belongs to the technical field of
industrial wastewater treatment equipment. The device comprises a
submersible pump, which sucks
wastewater into a
cyclone aeration cylinder; a
spiral flow guide groove is arranged in the lower cylinder section of the
cyclone aeration cylinder, the lower part of the middle cylinder section is a first cyclone mixing unit, the upper part is a second shearing and crushing unit, a
spoiler structure is arranged in the upper cylinder section, and a
diffusion cover is arranged at the top; an external air injection manifold, which provides a downward pressure for the cyclone aeration cylinder, is arranged; a
gas supply unit, which provides air for the cyclone aeration cylinder and the external air injection manifold, is arranged; a sensor unit, which monitors
wastewater quality and
vertical displacement of the aeration cylinder, is arranged; a collaborative dosing unit, which adds reagents to the cyclone aeration cylinder, is arranged; and a
control unit, which adjusts the flow of the
submersible pump, the air supply of the
gas supply unit and the adding amount of the collaborative dosing unit according to
wastewater quality, is arranged. The application offsets the
buoyancy of the cyclone aeration cylinder through the external air injection manifold, and improves the aeration effect in combination with the multi-stage cyclone structure.
