Description
Technical field
The utility model is related to a kind of air filtration units, and power plant water manufacturing system demineralized water is used for more particularly, to one kind
The bubble distributing air filtration unit of case.
Background technology
At present, the especially coastal power plant in domestic power plant is designed with water manufacturing system, in the sweet-water tank of water manufacturing system
Storage water needs to be designed with open loop system, in order to when liquid level changes at any time in water tank, keep high water tank upper stabilizer
Air pressure and normal level change.Open loop system during liquid level variation, can be inhaled extraneous gas by tank top pneumostome in water tank
Enter in water tank.At this point, the sundries adulterated in extraneous gas, salinity will enter in water tank, when high water tank changes in liquid level
There is convection current in portion's gas, gas can be contacted with the demineralized water occurrence of large-area in water tank, and the sundries in gas, salt branch are molten at this time
Solution causes the deterioration of water quality in water tank in demineralized water, makes the water quality into boiler circuit unqualified and influences boiler circuit
Operational reliability.
The deterioration of water quality in sweet-water tank is solved, main consideration main at present will be purified into the extraneous air in water tank,
The sundries in extraneous air, salinity is avoided to enter in water tank, keeps the stabilization of water quality in water tank.
Existing sweet-water tank air cleaning unit is using floating roof, floating ball isolation air and water seal arrangement isolation method.It is floating
Top, the mode of floating ball isolation air install floating seal additional in sweet-water tank, when installation need to the structure in water tank into
Row is changed and invested larger；And since floating roof, floating ball use plastic material, it is necessary to periodically be replaced to it.Water seal arrangement every
From medium using water or alkaline solution, be filtered, be unable to reach to water tank by the larger impurity in U-shaped water seal air
The air of interior disengaging is filtered；And need periodically to install filtered fluid additional, maintenance is larger.
Utility model content
Technical problem to be solved in the utility model, be just to provide a kind of automatic non-maintaining filtering of energy is used for power plant
The bubble distributing air filtration unit of water manufacturing system sweet-water tank is realized and the air for passing in and out sweet-water tank became more meticulous
Filter.
Above-mentioned technical problem is solved, the technical solution adopted in the utility model is：
A kind of bubble distributing air filtration unit for power plant water manufacturing system sweet-water tank fills filtrate including one
Container 9, the container top is equipped with single-phase breather valve 8 and connects air, and side wall is equipped with air inlet 5 and is circumscribed with water seal overflow
The overflow port of pipe 6, bottom are equipped with blowdown valve 7, it is characterized in that：Inside the container, three cavitys are divided into from the bottom up, according to
Secondary to be equipped with the first order, the second level, third level disperser (1,2,3), the air through-flow area of the three-level disperser increases step by step
Adduction uniformly disperses bubble in container, the air outlet slit diameter of three-level disperser reduces step by step, the air of the final third level
Outlet diameter is 0.23mm.
So may be such that reduces between the flow velocity of micro bubbles in a liquid, increases the time of contact of bubble and liquid, carries
High filtrate is to the filter capacity of bubble.
There are one the containers that air inlet and numerous minitype gas export for tool on wall for the first order disperser.
The second level and third level disperser is made of one, for the container with upper plate and lower plate, upper plate
Stomata is all provided with lower plate, respectively as the third level and second level disperser.
The container side wall is provided with Liquid level outlet, equipped with automatic liquid level control valve 4.
The filtrate is derived from the flowing had clean water in water manufacturing system sweet-water tank by oneself and filtering water is kept equipped with water pump.
The technique effect of the utility model is embodied in：
The filtering advantage of the present apparatus mainly using bubble Multistage dispersion mode, bubble is finally dispersed into a diameter of
0.23mm micro bubbles, make bubble fully and filtering liquid contact and filter after enter water tank in, filtering liquid in filter
Water is had by oneself as filtering liquid using water tank, and keeps the long-term flowing and cleaning of filtering water, low pressure is set at the top of filter
Poor one-way breather valve, when high water tank rise needs efflux gas, check valve, which automatically turns on, keeps stable gas pressure in water tank.Filter
Liquid level is relatively low in clear device, can keep the reliability of cisten mechanism to avoid occurring excessive negative pressure in water tank.Filter is set
Water seal overflow pipe.
This kind of structure filter leads to design using positive and negative bi-directional air：A, B is respectively that air entry/exit sweet-water tank connects
Mouthful, when outside air enters device by B, enter after 3 grades of filter devices carry out filtering from A in sweet-water tank；Sweet-water tank
Interior air is redirected back by A in cylinder, is discharged from top low voltage difference check valve rear exhaust port C.It is divided into minimum liquid level
Maximum gas-liquid reactivity is counted, makes to pass into the gas after filter filtering and is sufficiently cleaned.System uses certainly
Non-maintaining design is moved, structure is reliable.
