JDAF jet air-floatation device

Working principle: Air flotation is a liquid-solid separating process in wastewater treatment. When particle formed in water as suspended solid, namely raw water contains fabric, sand, sludge and other solid or dissolving type water or becomes like gels after chemincal and physical treatment had transfer to suspended solid, is adhered and wraped by sufficient fine air bubble, specific gravity of particle is smaller than that of water that access to liquid-solid separation. Application: - For paper mill, be used to reclain the white water from paper machine, fibre from medium stage wastewater and lignin from black liquid. - Liquid- solid separation for emulsified liquid and oil wastewater from machenical or petroleum industry - Painting desposal and Printin and dying wastewater treatment from Auto industry or other fields. - Pre-treatment for slaughter and food industry - Liquid-solid separation for agent dosage of non-degradation by biological roganic - Liquid-solid separation of chemical process for electroplating wastewater or sewage containing heavy metal ion - Water treatment for urban running water or protable water. - Liquid-solid separation and sludge thicken for excess sludge during the wastewater treatment process Manufacture feature : (I) Floating upward tank uses reinforced concrete structure; its main equipments are as following: 1. Dissolved gases system: 1) Centrifugal pump unit: pressure pump of dissolved gases water, water circulating pump, the pressure value is about 0.3 MPa¡«0.35 MPa; 2) Dissolved gases tub: working pressure of the tub is 0.30-0.33 MPa (material:Q235A) (accompanied by pressure gauge and USERPage - 3 -4/20/2012water leveler); 3) High efficient gas jet unit: working jet equipment and circulating air adding jet equipment unit installed in the tub (material quality is 1Crl8Ni9Ti); 4) Vacuum air intake valve; 2. Water relief and collecting system: 1) Relief and mixing device of raw water and dissolved gases; 2) Water level adjusting device of floating upward tank in water collecting plant; 3. Stirring machine: (used for slag floating and air releasing) equipped with stirring device, electric motor and speed reducer. 4. Slag eliminator: equipment used to eliminate floating particles. 5. Electric control system: Power Distribution Cabinet (control working pump, circulation pump, stock pump, stirring machine, and slag eliminator). (II) For the engineering that water quantity used is relative small adopts steel integrated structure, it can be applied after that all equipments are installed, corollary equipment are complete, and the electric power source is linked.
