Figure and specific embodiment are described in further details.
Embodiment 1
As shown in figure 1, the present invention a kind of high efficiency air float machine include air supporting reaction tank 1, clear water reserviors 2, scum silica frost pond 3, water pipe 5,
Bubble release pipe 6, slag-scraper 7, air dissolving system, water inlet and dosing mouth；The air supporting reaction tank 1 and clear water reserviors 2 are by dividing plate 4
Separate；The clear water reserviors 2 are provided with delivery port；The scum silica frost pond 3 is arranged on the top of air supporting reaction tank 1；The slag-scraper 7 is located at
The top of air supporting reaction tank 1, slag-scraper 7 include chain, two sprocket wheels and multiple scum boards, and two chains are connected by chain
Wheel, multiple scum boards are fixedly installed on chain, sprocket wheel drives the scum board on chain, by air supporting reaction tank 1 scum silica frost scrape into
Scum silica frost pond 3.The scum silica frost pond 3 is provided with slag notch.
The water pipe 5 is arranged on air supporting reaction tank 1 close to the position of bottom of pond, and water pipe 5 is along the length of air supporting reaction tank 1
The tubular structure of direction extension, multiple apertures, and one end closing of water pipe, the other end are provided with the bottom even of water pipe
Connected through dividing plate 4 with clear water reserviors 2.
The bubble release pipe 6 is vertically installed at the side away from clear water reserviors 2 in air supporting reaction tank 1.Bubble release pipe 6 wraps
Include blast pipe 61, VERTICAL TUBE 62, cyclone pipe 63, bend pipe 46 and oviduct 56, the blast pipe 61, VERTICAL TUBE 62, cyclone pipe 63,
Bend pipe 64 and oviduct 65 are sequentially connected logical.Multiple swash plates 66 parallel along the opening direction of oviduct 65 are provided with oviduct 65.
The water inlet discharges the upper end phase of pipe 6 with feeding opening with static mixer 12, bubble successively by three-way connection
Even.
The air dissolving system includes reflux pump 8, dissolving 9, air compressor machine 10 and bubble release 11；The water inlet of reflux pump 8
Mouth is connected with clear water reserviors 2, and the delivery port of reflux pump 8 is connected with the water inlet of dissolving 9, and the delivery port of dissolving 9 connects successively
Connect VERTICAL TUBE 62 and the intersection of cyclone pipe 63 in bubble release 11 and bubble release pipe 6, the air inlet and pneumatics of dissolving 9

In the embodiment, the specific implementation process of sewage disposal is as follows：
For sewage after air supporting water inlet flows into air floatation machine, the flocculant flowed into dosing mouth is together mixed by static mixer 12
Close, then VERTICAL TUBE 62 is flowed into from the top of bubble release pipe 6；Dissolved air water in dissolving 9 is discharged micro- by bubble release 11
Bubble, the bottom of the dissolved air water inflow VERTICAL TUBE 62 with microbubble, sewage relative reverse flow in VERTICAL TUBE 62 with microbubble,
Complete the abundant collisional mixing of the wadding grain in microbubble and sewage, microbubble participate in coacervation process and and wadding grain copolymerization and big,
So as to produce copolymerisation, bubble wadding EVA is formed；Microbubble and sewage co-flow again, successively by cyclone pipe 63, bend pipe
64, and be diffused into through oviduct 65 in whole air supporting reaction tank 1, microbubble rotates with sewage in cyclone pipe 63 to be mixed, and is completed
Effectively stick, the bubble flco for forming density less than water enters air supporting reaction tank 1；Microbubble and sewage are relatively inverse in VERTICAL TUBE 52
To copolymerisation caused by flowing, caused flco bubble is set to be clipped among wadding grain, microbubble has played cohesion, makes micro- gas
Bubble is embedded in inside flco securely, and bubble flco is not easy to be desorbed during floating, and scum silica frost is stable and is not easy.Steep flco
Liquid level is floated up in air supporting reaction tank 1, forms scum silica frost.Rotated by the sprocket wheel of slag-scraper 7, drive the scum board on chain
Moved horizontally on the surface of air supporting reaction tank 1, scum silica frost is scraped in scum silica frost pond 3.Sewage occurs in bubble discharges pipe 6 with microbubble
Reverse-impact and stick in the same direction, improve the interaction of microbubble-particle, enhance the Adhering capacity of microbubble, enhance
The stability of flco is steeped, significantly increases microbubble particles collision efficiency, the adaptability of sewage quality change is significantly increased.
Swash plate 66 in oviduct 65 plays a part of rectification.Because sewage and microbubble during bubble discharges pipe 6 when reacting, part is micro-
Bubble can form gas, and this portion gas is discharged by blast pipe 61.
The aperture that the clear water of completion is set by the bottom of water pipe 5 is handled in air supporting reaction tank 1 and is collected and flow into clear water reserviors
2, the middle part of clear water reserviors 2 is distinguished water and returns pump to dissolving 9 by reflux pump 8, while air compressor machine 10 pressurizes and inputted sky to dissolving 9
Gas, air dissolve in clear water in dissolving 9 and form dissolved air water, and dissolved air water flows into bubble release 11 and discharges microbubble, with micro-
The bottom cycle that the dissolved air water of bubble flows into VERTICAL TUBE 62 is reacted；Another part clear water passes through delivery port stream in clear water reserviors 2
Go out, completion processing.
