Description
Technical field
The invention belongs to the defoaming technology of water body, a kind of spiral-flow type of the mechanical means of power plant cooling water body is specifically related to
Defoaming device.
Background technology
Thermoelectricity or nuclear power plant generally use the direct-flow water supply system using surface water such as seawater as cooling water source, this certainty
Substantial amounts of recirculated cooling water is brought to be discharged into environment water again.In order to reduce operating cost and ensure that taking and discharging system is transported safely
OK, generally, power plant's draining goes out stream mode, i.e. drain outlet leading edge provided with siphonic water-collecting well using siphonic water-collecting well, is set in siphonic water-collecting well
There is the effluent weir of certain elevation, to reduce influence of the off-lying sea tidal level change to siphonic water-collecting well Upstream section.In view of off-lying sea tidal level is continuous
Change, certainly exists certain water-head between siphonic water-collecting well excessively stream weir up-stream face and the off-lying sea water surface, causes siphonic water-collecting well drainage effluent
The situation fallen and stream is often presented, in the process a large amount of aerations of water body, causes to contain a large amount of gas behind siphonic water-collecting well weir in water body
Bubble.At the same time, it is general to use in order to eliminate attachment of the aquatile to recirculated water taking and discharging structures and the obstruction to runner
Chlorination mode or other chemical substances to be to kill marine growth in circulation, due to the material after marine growth Residue decay with
And the influence of the medicament added in water etc., receiving water body physical property changes, and showing as the foam in draining should not crumble and fall.
These substantial amounts of weak yellow foams are discharged into behind environment marine site with cooling water, are flown away everywhere under the effect such as ocean current, not only serious shadow
Ring by receiving the water quality and perception in waters, and the metallic structures that the saliferous water smoke splashed can be near heavy corrosion discharge outlet
With the vegetation of earth's surface.Some in particular cases foam is also possible to spill into plant area, has a strong impact on the environment on power plant periphery.
Existing coastal power plant employs certain energy dissipating froth breaking measure, but is difficult in adapt to the demand of tidal level change,
Draining is easy to aeration and carried to off-lying sea discharge under the conditions of low tide, forms foam pollution band；The second is existing engineering measure without
Method prevents foam from producing completely, and basic use blocks the measures such as bubble wall and contains foam in siphonic water-collecting well weir rear region, weir rear region bubble
Foam is gradually accumulated, it is easy to the phenomenon of foam overflow siphonic water-collecting well, pollution plant area etc. occur, further need to suppress bubble using engineering measure
Foam is accumulated.In a word, existing engineering measure can not still adapt to that marine site engineering drainage is anti-foam, froth breaking demand completely, seek more suitable
Suitable Coastal Power Plant draining is anti-foam, debubbling method, to eliminating or reducing influence of the foam to environment, improves power plant's surrounding body ring
Border is significant.
The content of the invention
The invention provides a kind of reasonable in design, the obvious spiral-flow type defoaming device of defoaming effect, it passes through guiding

A foam is provided with vivo and collects body, and the foam is collected and is equipped with power-actuated hairbrush froth breaker on body.
Concretely, the impeller guide froth breaking body is drum structure, and the outer wall of the impeller guide froth breaking body is also set up
There is a water body flow export, the water body flow export is set along the external wall tangential direction of impeller guide froth breaking, the water body flow export
Horizontal level be less than the inflow entrance.
In one embodiment, the flow-limiting valve of restricted water flow is set on the water body flow export.
In one embodiment, it is a circular cylinder body that the foam, which collects body, and the circular cylinder body is erected at the impeller guide
On froth breaking body, the foam is collected body and is arranged concentrically with impeller guide froth breaking body.
In another embodiment, the bottom that the foam collects body is located at lowest water level arrangement above, and the foam is collected
The lower edge distribution of body opens up foam and enters breach.
In a further embodiment, the foam enters what is set up and formed an angle with foam water direction of flow on the outside of breach
Oblique baffle plate.
In another embodiment, the foam collects the centre frame of body provided with a brush stroke set around the central rotation,
The brush stroke is driven by motor rotation and rotation simultaneously.
The spiral-flow type defoaming device is designed using concentric telescoping structure, and impeller guide froth breaking body uses drum structure, its
The band foam water body for making entrance by the inflow entrance of tangential direction water conservancy diversion and the bucket wall of impeller guide froth breaking body produces eddy flow power,
The centrifugal force that the eddy flow is produced makes foam assemble to the center of impeller guide froth breaking body.And the impeller guide froth breaking body in status
The water body flow export of upper setting is excluded the water body after foam is centrifuged, by setting restricted water body stream on water body flow export
The flow-limiting valve of amount can control the change of liquid level, keep the effect of foam aggregation.The foam being arranged concentrically with impeller guide froth breaking body
It is also a circular cylinder body to collect body, and its underpart edge distribution opens up foam and is located at more than liquid level into breach, can effectively promote
Make the aggregation of foam.Foam enters the oblique baffle plate set up on the outside of breach with being formed an angle with foam water direction of flow, can hinder
Foam outside gear breach is simultaneously oriented to it and collects internal aggregation to foam.Needle-like is densely covered with the brush stroke that the central rotation is set
Hairbrush, can make the hairbrush on brush stroke collect the foam contacting on body top with foam and puncture foam wall by Mechanical Driven,
