Description
Technical field
The invention belongs to technical field of sewage, is related to a kind of pressurizer mechanism for sewage pressure floatation air.
Background technology
Oil slick and solid particulate matter are usually contained in sewage, existing purification method is typically settled process, i.e., using precipitation
Pond is precipitated, sedimentation basin be using precipitation go water removal in suspension a kind of structures, the equipment to purify water.Utilize
The natural sedimentation of water or acting on to remove the suspension in water for coagulating sedimentation.Sedimentation basin is divided into horizontal sedimentation basin by water (flow) direction
With vertical sedimentation basin.Sedimentation effect is decided by the residence time of the flow velocity and water of sedimentation basin reclaimed water in pond.In order to improve precipitation
Effect, land area is reduced, it is more using the incorgruous sedimentation tank of honeycomb inclined-tube, accelerating purifying pool, plusator etc. at present.Precipitation
Pond is widely used in the treatment of waste water.
But sedimentation basin can only solve the problems, such as separation of solid and liquid, for oil slick, prior art is realized using Bubble-floating Method, but is such as existed
Air supporting is carried out in settling tank, water body can be stirred, then can not realize the effect of sedimentation.Therefore flotation tank and settling tank are divided equally
Independence is opened, due to set multiple ponds, therefore floor space is relatively large.
Such as Chinese patent literature discloses a kind of sedimentation basin [application number：201510450441.6], it includes sedimentation basin
Body, bottom face is provided with activated carbon adsorption layer in the sedimentation basin body, will be precipitated by dividing plate in the sedimentation basin body
Pond is divided into settling zone and clean water area, and the middle and upper part of the dividing plate is provided with gap, and the both sides of the sedimentation basin body are respectively equipped with
Water inlet pipe and outlet pipe, the water inlet pipe are located in settling zone, and the outlet pipe is located in clean water area, are set below the water inlet pipe
There is the deflector being obliquely installed, the surface of the deflector is provided with ultraviolet sterilizer.Such scheme can only just realize sedimentation
Effect, the effect of water-oil separating can not be realized.
The content of the invention
Regarding the issue above, the present invention provides a kind of pressurizer mechanism for sewage pressure floatation air.
To reach above-mentioned purpose, present invention employs following technical proposal：
A kind of pressurizer mechanism for sewage pressure floatation air, including pressurized canister, pressurized canister are arranged with forced feed outside
Tank, described pressurized canister are fixedly connected with forced feed tank, and the forced feed pipe of forced feed tank is communicated with pressurized canister, is added
Air inlet pipe is provided with pressure tank, several exhaust disks are connected with air inlet pipe, described exhaust disk inside pressurized canister with connecting, institute
The air inlet pipe connection compressed air generator stated, the top of described pressurized canister is fixedly connected with forced feed tank top.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, axially spaced-apart of some exhaust disks along air inlet pipe
It is uniform to set, and be vented on disk and be densely covered with venthole, compressed air generator is compressed air cylinder or air compressor.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, the bottom bore of described pressurized canister gradually contracts
The first pressurized precipitation area of small formation, the first pressurized precipitation area bottom is connected with the first pressurised exhaust pipe and the first pressurised exhaust pipe
Extend outside forced feed tank.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, described forced feed pot bottom bore is gradual
Reduce and form the second pressurized precipitation area, the second pressurized precipitation area bottom is connected with the second pressurised exhaust pipe and second pressurised exhaust
Pipe extends outside forced feed tank.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, one is fixed with the inwall of described pressurized canister
Individual the first spiral board being inclined to set, the first spiral board are located at the top of forced feed pipe and the outlet face of forced feed pipe
The outer wall of first spiral board.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, the inwall of described forced feed tank is fixed with
One the second spiral board being inclined to set, is additionally provided with forced feed mouth on forced feed tank, the second spiral board positioned at pressurize into
Material mouth top and forced feed mouth the second spiral board of face.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, described the first spiral board and the second spiral board
In inverted round stage taper.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, described the first spiral board and the second spiral board
The helically downward spiral shape in direction.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, the first described pressurised exhaust pipe and second adds
The axial line of pressure delivery pipe is parallel to each other.
In the above-mentioned pressurizer mechanism for sewage pressure floatation air, flotation tank is connected with the top of described pressurized canister
Mechanism, venthole gather in the upper and lower surface and side wall of exhaust disk.
Compared with prior art, the advantage of the invention is that：
In pressurized with compressed air mixed process, separation of solid and liquid can be realized to sewage, make solid particle from pressurized canister and
Forced feed pot bottom is discharged, and compressed air is well mixed with sewage by being vented disk, before being created well for next step oil extraction
Put condition.
In release pond, because gas mixing is uniform, therefore release process is also uniform, oil slick is fully divided with sewage
From realizing water-oil separating, reduce the COD value in sewage, then after the top overflow by release pond and run-off, oil slick is received
Collection, is sufficiently separated with sewage.
The present invention can realize separation of solid and liquid, and and can realizes water-oil separating, can reduce the COD value in sewage, can also improve
The clarity of sewage.
Further advantage, target and the feature of the present invention embodies part by following explanation, and part will also be by this
The research and practice of invention and be understood by the person skilled in the art.
