Separating effect.
The middle and upper part and middle and lower part of air flotation tank 10 is respectively equipped with sewage tangential entry 102 and recirculated water tangential entry 103, dirty
Water and recirculated water are entered in tank along the tank body tangential direction of air flotation tank 10, can so optimize sewage fluidised form, strengthen eddy flow strong
Degree；Sewage tangential entry 102 and recirculated water tangential entry 103 are set to two and horizontal symmetry is arranged, can so keep dirty
Hydraulic equilibrium during water eddy flow, reduces impact of the slip phenomenon to disposal ability.
The middle and upper part of air flotation tank 10 is provided with guide shell 104, and guide shell 104 is concentric with air flotation tank 10, boring, top
Cylindrical, bottom is in inverted tubaeform, and bottom is in 45 DEG C with horizontal direction, and certain opening is left between the inwall of air flotation tank 10
Between emptying.Guide shell 104 makes the appropriate eddy flow of sewage acquisition strong by forming annular space in its outer wall and the inwall of air flotation tank 10
Degree；The molten gas sewage of air flotation tank 10 is entered Jing after cyclone air-flotation separation, the water after process is from air flotation tank from sewage tangential entry 102
10 inwall sides flow downward, it is to avoid the water after processing is migrated directly down the secondary dissolved air flotation implemented to air flotation tank middle and lower part
During adhere to oil droplet and particle the floating of bubble impact, intersect so as to avoid flow field.Guide shell 104 is unique
Structure design can make that the inner eddy flow intensity of air flotation tank 10 is bigger, Flow Field Distribution more rationally and space availability ratio is higher.
The middle part of air flotation tank 10 is provided with cylindrical oil pooling cylinder 105, and oil pooling cylinder 105 is concentric with air flotation tank 10, and its is a diameter of
0.2～0.5 times of the diameter of air flotation tank 10；Less than 104 2cm of guide shell top, its bottom is connected with extension to the top of oil collection barrel 105
Oil exit pipe 110 to air flotation tank 10.Oil pooling cylinder 105 is located at the center of air flotation tank 10, so can farthest reduce
Tank body rocks the impact to oil phase liquid bit manipulation, because the center of tank body is movement velocity minimum point；Oil pooling cylinder 105 is played simultaneously
The effect of the stable center oil column of air flotation tank 10.
The bottom of oil pooling cylinder 105 of air flotation tank 10 is fixed with unhurried current plate 106, and unhurried current plate 106 diameter is equal to the bottom of guide shell 104
Diameter, unhurried current plate 106 is used for preventing treated water outlet from producing vortex because of water outlet excessive velocities.

90th, pressure-regulating valve 100, oil phase Liquid level adjusting valve 120 and water phase are respectively equipped with oil exit pipe 110 and purified water outlet pipe 130
Liquid level adjusting valve 140, adoption rate integral differential (PID) feedback control pressure respectively to air flotation tank 10, oil phase liquid level and water
Phase liquid level is implemented to automatically control.When the fluctuation such as the pressure of sewage, temperature, flow, oil content and sewage handled by air flotation tank 10
When water quality characteristic changes, the operating parameter such as the pressure of air flotation tank 10, oil phase liquid level and water phase liquid level can be adjusted and
Reset, so as to improve sewage treating efficiency.
The bottom centre of air flotation tank 10 is provided with spoil disposal sandpipe 150, for the silt particle of the bottom collection of periodic exhaustion air flotation tank 10,
Air flotation tank 10 is substantially the solid four-phase separator of an oil gas water.
The operating pressure of air flotation tank 10 is 30～300kPa, using purified natural gas as air supporting source of the gas, processes 1m3Sewage
The air supporting tolerance of needs is not more than 0.1sm3Air supporting gas.
The course of work of the present invention：The static state that sewage is connected by the Jing of sewage water inlet pipe 50 with purified natural gas air inlet pipe 60
After the molten gas of blender 20, air flotation tank 10 is entered by the sewage tangential entry 102 of two horizontal symmetry arrangement, it is a large amount of intensive micro-
Bubble instant decompression discharges, and sewage produces weak eddy flow, weak rotation in the annular space of the inwall of air flotation tank 10 and the outer wall of guide shell 104
The centrifugal force field that stream causes order about the larger water of density to the inwall of air flotation tank 10 move, and bubble, oil droplet and particle etc. compared with
Light composition will migrate near the outer wall of guide shell 104, and in the process bubble and oil droplet and particle collide adhesion, logical
The floating for crossing bubble realizes flotation, and gradually coalescence becomes big for oil droplet and particle, constantly rises along the outer wall of guide shell 104 and is brought to
Liquid level and flow into oil pooling cylinder 105, then Jing oil exit pipes 110 are discharged；At the same time, from row's natural gas tube 90 at the top of air flotation tank 10
The natural gas of extraction is mixed with the process after-purification water of the supercharging of Jing water circulating pumps 30 by natural gas return duct 80 in ejector 40
Close, and sprayed in air flotation tank 10 by two recirculated water tangential entries 103, a large amount of intensive microbubbles are produced again, carry
The recirculated water of a large amount of microbubbles is uniformly distributed in the bottom of air flotation tank 10, and oil droplet and particle are sticked on bubble along oil pooling cylinder
105 outer walls uniformly ascend into oil pooling cylinder 105, complete second dissolved air flotation of sewage.Purification water section after process is by following
Ring water pump 30 is transported to ejector 40 and participates in molten gas, and remaining is all discharged by the purified water outlet pipe 130 of the bottom of air flotation tank 10.
In the course of work of the present invention, the dischargeable capacity of air flotation tank 10 is divided into two working regions, and liquid level is cut with recirculated water
It is used for strengthening hydrocarbons contact and oil-water separation, referred to as treatment region to the space between import 103, sewage is thrown in the region in gravity
The linear rotation of thing, lasting sewage is tangentially entered, circulates the eddy flow centrifugal motion that the gentle floating gas injection of water circulation maintains treatment region
And floatation process；Space of the recirculated water tangential entry below 103 is used for the collection of purified water and silt particle, and this region is referred to as collected
Area.
The above, is only presently preferred embodiments of the present invention, and any pro forma restriction is not made to the present invention, all
It is above example is made any simple modification, equivalent variations and modification according to the technical spirit of the present invention, still falls within
In the range of technical solution of the present invention.
