Integrated multifunctional air-floatation water purifier

Abstract

The invention discloses an integrated multifunctional air-floatation water purifier, and belongs to the technical field of water treatment. The integrated multifunctional air-floatation water purifier comprises a vertical cylinder; the side face of the vertical cylinder is provided with a water inlet, a dissolved air inlet, a water outlet, a residue discharge hole, an overflow gate, an air outlet and an emptying port; an concentric inner cylinder is arranged on the middle lower part of the vertical cylinder; an air-liquid mixing device is arranged in the inner cylinder; the water inlet extends into the inner cylinder; the upper opening of the inner cylinder is open; an obconical floating residue collecting cover is arranged in the vertical cylinder above the inner cylinder; a floating residue concentrator on the top of the floating residue collecting cover is communicated with the residue discharge hole; a mud and sand collecting concentrator is arranged on the bottom of the inner cylinder, and is communicated with a mud discharge pipe on the bottom of the vertical cylinder; a space between the upper part of the inner cylinder and the vertical cylinder is designed to be a filter area; a space between the middle lower part of the inner cylinder and the vertical cylinder is designed to be a purified water area; a space at the upper end of the floating residue collecting cover is designed to be a water outlet area; the dissolved air inlet is connected with a plurality of groups of Venturi pipes and then is communicated with the purified water area on the lower part of the vertical cylinder through an external water pump; and a water communicating built-in flow transfer pipe is arranged between the purified water area and the water outlet area. The integrated multifunctional air-floatation water purifier has long service life, high automation degree, low operating cost without secondary pollution, is easy and convenient to operate and runs in a closed mode.

Description

technical field [0001] The invention relates to a solid-liquid separation device, which belongs to the technical field of water treatment, in particular to an integrated multifunctional air flotation water purifier. technical background [0002] At present, the physical and chemical treatment methods of water purification at home and abroad include natural precipitation, dosing, coagulation, reaction, air flotation separation, and a series of unit treatment equipment and facilities. The process is long and the residence time is long. High energy consumption, large equipment footprint, large investment, many management personnel, high labor wages, and relatively large waste of resources. Contents of the invention [0003] The present invention provides an integrated multi-functional air flotation water purifier just to overcome the above-mentioned shortcomings. The main innovation is to concentrate dosing, coagulation, reaction, sedimentation, flotation, and filtration in o...
