Description
Technical field
The invention belongs to field of Environment Protection, be specifically related to Yi Zhong rotation turn of tidal stream air-floating apparatus.
Background technology
Air-floating apparatus is sewage disposal device that is liquid-solid, Liquid liquid Separation.
Tradition air supporting is that sewage dissolves in air under stress, and molten gas decompression release in separate tank, utilizes the micro bubble absorption discharged in decompression process to carry solid, liquid impurity particle in water and rise and be removed.So-called separate tank is generally open type run by gravity pond body, or is the long pond of flat flow rectangle, or is circular radial-flow pond body.So-called molten gas decompression release utilizes the gas characteristic that solubleness is directly proportional to pressure in water, the water incorporating air under pressure (usual 0.3-0.5MPa) is released in separate tank, excess air microbubble shape overflows, and its specific surface area is very big, possesses the liquid-solid particle ability of absorption.And, often for improving fractionation by adsorption effect, needing to carry out medicament coagulating treatment, being often furnished with reaction tank.
Solid, liquid impurity particle rises and removed degree and flow velocity, and climb is relevant, obtains deep purifying, just needs larger occupation area of equipment and space.Improve plant efficiency, minimizing is taken up an area and cost of investment is technology pursue target.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provides Yi Zhong rotation turn of tidal stream air-floating apparatus.
Technical scheme: in order to reach foregoing invention object, the: mono-Zhong rotation turn of tidal stream air-floating apparatus that the present invention has specifically come like this, comprise horizontal cylindrical cylindrical shell and molten gas equipment, described cylindrical shell is the enclosed construction with inspection manhole, Inlet and outlet water, turnover gas and Residue extraction pipeline interface, inside is divided into coagulating room with lateral partitions, some separate chambers, and scum silica frost, clean water chamber; With wash plate, above-mentioned each room section is separated, form 1 font of a band circle, and 1 does not have intersection point (namely with wash plate, above-mentioned each room section being divided into font) with circle; Described molten gas equipment is air dissolved pump and reliever, and air dissolved pump extracts processed sewage and sucks gas pressurization on liquid level send into separate chamber from scum silica frost, clean water chamber bottom, and gas dissolved water is through reliever decompression release; Described cylindrical shell top be provided with air dissolved pump suck Link Port, cylinder body bottom is provided with gas under pressure admission port, release gas dissolving in water and adsorb solid, liquid impurity be scum silica frost float, divided gas flow accumulates on liquid level, be air dissolved pump extract, recycle; Described coagulating room is provided with sewage inlet, is provided with outlet of purifying waste water bottom scum silica frost, clean water chamber.
Wherein, described molten gas equipment receives the gas of release to be air or nitrogen.
Wherein, institute's rotation turn of tidal stream air-floating apparatus of stating is by gravity system or have pressing system to provide gaseous tension to maintain liquid level, thus water outlet can be discharged in the high position needed.
Wherein, pressing system is had to be open a hole at cylindrical shell top to be connected with source capsule of calming the anger, by pressure maintaining valve control gas influx described in.
Principle of work of the present invention is: treatment sewage is after entrance access to plant, forming ∵ shape rotary current rotation through foot passage successively turns by coagulating room and stage trapping room, liquid has free surface in tank, under coagulation and molten gas effect, solid, liquid impurity floats to liquid level, removes at liquid stream and under scraping the effect of slag equipment from fluid surface, liquid stream is purified, and purifies waste water to export discharge through water purifying chamber.
Beneficial effect: the present invention, compared with conventional art, has the following advantages: the present invention possesses stage trapping room, sewage resolution is high, floor space is little, essential safety, environmental protection, can pressure state be adopted as required to run, coordinate with subsequent treatment process elevation and simplify, without the need to promoting, energy-conservation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
