Abstract
A gas water mixer, which belongs to the gas water mixing device technology field, is characterized in that the mixer has a four-way structure with unequal length and all the four directions have an opening respectively, wherein the top end is equipped with an air inlet nozzle, the bottom of which has fumaroles with bubble diameters from twenty to forty mm. A sidewall is equipped with six to eighteen fumaroles with bubble diameters from five to forty mm. The lower end is connected with a duct, which has a pulse pressure reducing valve. The utility model can make the bubble diameters of the gas water mixture controllable, which goes in the gas water mixer, and the bubbles break as well as control the energy produced by the breaking and the breaking period. If the utility model is used to wash the coils of a water internal cooling motor, a more ideal washing effect is obtained.
Description
Technical field:
The utility model relates to a kind of gas-water mixer.
Background technology:
At present, along with the continuous increase of generating set capacity, the internal water cooling technology is widely used, and the above steam turbine generator of modern 200MW mostly adopts the type of cooling of water-hydrogen-hydrogen.But can be after the long-time running at hollow lead inwall deposition attachment, the electricity that influences cooling effect, water is led and the uniform distribution of cooling water in coil, like this, the reduction and the hot-spot that can cause the rising of generator coil temperature, dielectric level, the hollow lead causes the generator scaling loss with blocked when serious.For this reason; in design of Cooling System; disposed with normal inner cold water and flowed to opposite pipeline and valve; be used for when shutting down maintenance, carrying out regular backwash; the state of this back-flushing method flushing is stable flow velocity and flow; can not control bubble breaking and broken energy and the cycle that produces; effective to the attachment that hollow lead inner suspension thing and adhesion are little; but the deposit at and dead angle place strong to the inwall adhesion is just powerless; it is clean to be difficult to cleaning down; produce build-up effect thus, if things go on like this, generator certainly exists potential hidden danger.Simultaneously,, the insulation of generator can be had influence on, the possibility of heating, shelf depreciation and puncture can be caused when serious because polytetrafluoroethylinsulating insulating tube inwall attachment increases.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of gas-water mixer that can control bubble diameter, this gas-water mixer can be controlled bubble breaking and broken energy and the cycle that produces, the flusher that is used for the water-cooled generator coil, can control backwash rate, thereby reach even more ideal developing result.
The technical solution of the utility model is achieved in that it is all not isometric " four-way " structures of opening of a four direction, wherein upper port is provided with nozzle of air supply, the nozzle of air supply bottom has fumarole, its aperture is 20-40mm, sidewall has 6-18 fumarole, its aperture is 5-40mm, and lower port connects the conduit that the pulse pressure-reducing valve is housed.
Good effect of the present utility model is: make the bubble diameter that enters the air water mixed liquor in it controlled, and can make bubble breaking, broken energy that produces of control and broken cycle, the developing result that is applied to the water-cooled generator coil is even more ideal.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing: the utility model is all not isometric " four-way " structures of opening of a four direction, wherein upper port 1 connects by flange 2 or welds a nozzle of air supply 3, the fumarole 4 that it is 20-40mm that nozzle of air supply 3 bottoms have an aperture, the fumarole 5 that it is 5-40mm that sidewall evenly has 6-18 aperture, lower port 6 connects the conduit 8 that pulse pressure-reducing valve 7 is housed, left port 9 connects water inlet pipe, and right output port 10 connects outlet pipe.
During the utility model work, water is by the left port 9 of water inlet pipe inflow blender, and compressed air sprays in the blender through the fumarole 4,5 of nozzle of air supply 3, forms perpendicular cuts with the water of coming in, produce the air water mixed liquor, enter the generator hollow coil from the outlet pipe outflow through right output port 10.In order to cause air bubble expansion and the broken condition in the air water mixed liquor,, system's internal pressure state is changed at lower port 6 external pulse pressure-reducing valves 7.When valve was opened, system pressure reduced, and makes air bubble expansion until fragmentation, and when valve cut out, system pressure went up again, and the micelle of the water that is separated by bubble is again to draw close mutually at a high speed.Regulate the cycle and the speed of opening and closing, just can reach control bubble breaking and the level that releases energy, thereby the power that realizes flushing is regulated.
