Description
Technical field
The invention belongs to the defoaming technology of water body, is specifically related to a kind of spiral-flow type of the mechanical means of power plant cooling water body
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 using siphonic water-collecting well, i.e. drain outlet leading edge is provided with 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 that stream fallen often is presented, in the process a large amount of aerations of water body, causes to contain a large amount of gas in water body behind siphonic water-collecting well weir
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 medicament added in water etc., receiving water body physical property change, showing as the foam in draining should not crumble and fall.
After these substantial amounts of weak yellow foams are discharged into environment marine site with cooling water, flown away everywhere under the effect such as ocean current, not only serious shadow
The water quality and perception in receiving waters have been rung, and the metallic structures near the saliferous water smoke meeting heavy corrosion discharge outlet splashed
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 defoaming 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, uses to block the measures such as bubble wall and contain foam substantially and is steeped in siphonic water-collecting well weir rear region, weir rear region
Foam is gradually accumulated, and is easy to the phenomenon for 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 the demand that marine site engineering drainage is anti-foam, defoams 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, obvious spiral-flow type defoaming device of defoaming effect, it passes through guiding

Impeller guide defoaming is external to set tangential direction water conservancy diversion to enter the internal inflow entrance of impeller guide defoaming, impeller guide defoaming
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 defoaming body is drum structure, and the outer wall of the impeller guide defoaming body is also set up
There is a water body flow export, the water body flow export defoams external wall tangential direction along impeller guide and set, 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
Defoam on body, the foam is collected body and is arranged concentrically with impeller guide defoaming 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 on the outside of breach what is set up and formed an angle with foam water direction of flow
Oblique baffle plate.
In another embodiment, the centre frame that the foam collects body is 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 defoaming body uses drum structure, its
The bucket wall of body is defoamed by the inflow entrance and impeller guide of tangential direction water conservancy diversion makes the band foam water body of entrance produce eddy flow power,
Centrifugal force caused by the eddy flow assembles the center of foam to impeller guide defoaming body.And the impeller guide defoaming body in status
The water body flow export of upper setting excludes the water body after centrifuging foam, 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 defoaming 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 on the outside of breach the oblique baffle plate set up with being formed an angle with foam water direction of flow, can hinder
Gear breach outside foam and be oriented to its to foam collect in vivo aggregation.Needle-like is densely covered with the brush stroke set around the central rotation
