Reduced Pressure Flotation Also Called Vacuum Flotation

The gas analysis divided into pressurized flotation flotation process decompression flotation (or called vacuum flotation), three types of electrolytic flotation. Wherein the pressurized flotation process hasball mill foaming amount easy adjustment control, processes are flexible, etc., widely used; decompression rotary dryer flotation be operating under sealed conditions, only for the flotation separation of toxic gases or odorous volatile process; electrolytic flotation due to the large energy consumption, and is still in the research stage.Flotation machine

    Pressurized flotation, pressure flotation device is mainly composed by the pressure pump, air compressor, dissolved gas cylinders, pressure reducing valves, flotation cells. Its working procedures for: pressure pumps raw water or partially treated water together with a pressure of 0.196 to 0.49 MPa (2 to 5 kg force / cm 2) of the compressed air into the sealed dissolving tank, the water stays in the dissolved gas cylinders 1 to 5 minutes and then by the pressure reducing valve, together with the non-pressurized wastewater introducing open to atmosphericaac machinery pressure flotation, the air is precipitated in the flotation tank, and the object to form a foam or scum blade scrapings; water in the flotation tank stay within 10 to 30 minutes, the treated water is discharged from the other end of the bottom of the flotation cell or a groove.

    Reduced pressure flotation also called vacuum flotation, ball millso that air at atmospheric pressure was dissolved, and then in the closed vessel was evacuated under reduced pressure, the precipitated produce bubbles of dissolved gas under atmospheric pressure.Lime Kiln Electrolytic flotation is a bubble precipitation flotation column. The generation of the bubble is by electrolysis in the cathode and anode, respectively precipitate formation of H2 and O2.
