The utility model is characterized in that the utility model comprises an air-water separator connected to a fixed cold water tank, and a water sealing device connected between the fixed cold water tank and the air-water separator, wherein a water outlet pipe and a gas return pipe are arranged between the air-water separator and a water throwing disc of a generator; the air-water separator is provided with a water flow disperser for separating water and gas; a hole plate or a grid or a grill for dispersing the water flow is arranged in the water flow disperser. The utility model can separate air leaking into the water throwing disc of a double water inner cooling generator from a loop flowing into the fixed cold water tank, and the air can back flow to the water throwing disc of the double water inner cooling generator; the air pressure of the water throwing disc can be maintained, and the air can be prevented from further leaking into the water throwing disc of the double water inner cooling generator; accordingly, oxygen and carbon dioxide can be prevented from dissolving in cold water, factors making a copper wire rod of the generator corroded can be eliminated and an inner cold water treatment device of a generator can be ensured to effectively improve the pH value of inner cold water and reduce the conductivity of the inner cold water.
Description
Technical field:
The utility model relates to a kind of generator amature water coolant gas and water separator, and it belongs to water treatment field, particularly the water treatment device of thermal power plant's double water innercooling electric generator inner cold water system.
Background technology:
When generator stator cooling water system of thermal power plant moves,, cause the corrosion of generator unit stator winding copper conductor and decide the specific conductivity increase of cold water, the safety that jeopardizes generator because the corrosion product of generator unit stator winding copper conductor enters and decide cold water and form cupric ion.For addressing the above problem, present decide all ion exchange units in parallel in deciding the cold water circulation loop of chilled water system, or add the pH value that micro-alkaline matter improves inner cold water, reach and stop generator copper cash rod corrosive purpose.But for double water innercooling electric generator, since the gas leakage that the water-throwing disk of rotor loop causes, a large amount of airborne CO
2Incorporate inner cold water and make inner cold water pH value on the low side,, cause the defective and generator copper cash rod of inner cold water water quality to corrode even through ion-exchange or add art breading such as micro-alkaline matter and also be difficult to improve inner cold water pH value.
Summary of the invention:
The purpose of this utility model is to provide a kind of air double water innercooling electric generator water-throwing disk that bleeds that stops, thereby stop more oxygen and carbonic acid gas to dissolve in inner cold water, guarantee that the electric generator inner cooling water treatment device can effectively improve the generator amature water coolant gas and water separator of the pH value of inner cold water.
The purpose of this utility model is achieved in that
A kind of generator amature water coolant gas and water separator is characterized in that it comprises one to be connected the air water separator decided on the cold water storage cistern, to connect the liquid packing of deciding between cold water storage cistern and the air water separator; One outlet conduit and a gas backstreaming pipe are set between the water-throwing disk of described air water separator and generator; In described air water separator, be provided with a current decollator that is used for the dried up gentle body of branch.
Be provided with the orifice plate or screen or the grid that disperse current in the described current decollator.
Described liquid packing is a U-shaped pipe.
Described air water separator, liquid packing and gas return line are that corrosion resistant material is made.
The utility model can make the gas of the double water innercooling electric generator water-throwing disk that bleeds separate in flowing into the loop of deciding cold water storage cistern, be back to the double water innercooling electric generator water-throwing disk, keep the gaseous tension of water-throwing disk, stop the air double water innercooling electric generator water-throwing disk that further bleeds, thereby stop oxygen and carbonic acid gas to dissolve in inner cold water, elimination causes generator copper cash rod corrosive factor, guarantees that the electric generator inner cooling water treatment device can effectively improve the pH value of inner cold water and reduce electric conductivity of inside cold water.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Embodiment:
The utility model is further detailed for embodiment of the present utility model with accompanying drawing 1 below:
In the present embodiment, the utility model comprises and one is connected the air water separator 6 decided on the cold water storage cistern, connects the water segregator of deciding between cold water storage cistern 9 and the air water separator 67; One outlet conduit 10 and a gas backstreaming pipe 3 are set between the water-throwing disk 1 of described air water separator 6 and generator; Be provided with a current decollator 4 that is used for the dried up gentle body of branch at described air water separator 6.Be provided with the orifice plate or screen or the grid that disperse current in the described current decollator, help separating of water and gas like this.Be installed on the position of double water innercooling electric generator rotor water coolant backwater section, concrete mounting points can be determined according to the erecting stage situation.Described water segregator 7 can be made becomes a U-shaped pipe.In the present embodiment, described air water separator 6, liquid packing 7 and gas return line 3 are that corrosion resistant material makes, and help prolonging this use novel work-ing life like this.Gas backstreaming pipe 3 of the present utility model is provided with by-pass valve control 2 and by-pass valve control 5 and gas-pressure meter 11, and a bypass valve 8 in parallel with liquid packing 7 is set on air water separator 6.Directly closing control valve 2 and by-pass valve control 5 when this device does not move are opened this bypass valve 8.
Since the gas leakage that the water-throwing disk of double water innercooling electric generator rotor loop causes, a large amount of airborne CO
2Incorporate inner cold water and make inner cold water pH value on the low side,, cause the defective and generator copper cash rod of inner cold water water quality to corrode even through ion-exchange or add art breading such as micro-alkaline matter and also be difficult to improve inner cold water pH value.The utility model can make the gas of the double water innercooling electric generator water-throwing disk that bleeds decide by air water separator 6 gas-water separation in the backwater to be come out in the loop of cold water storage cistern in inflow.Because the effect of liquid packing 7, gas is back in the double water innercooling electric generator water-throwing disk 1 by gas backstreaming pipe 3, keep the gaseous tension of water-throwing disk 1, stop the air double water innercooling electric generator water-throwing disk that further bleeds, thereby stop oxygen and carbonic acid gas to dissolve in inner cold water.Therefore, under the situation that need not change water, can guarantee that still the electric generator inner cooling water treatment device can effectively improve the pH value of inner cold water and reduce electric conductivity of inside cold water.
The comparative analysis of present embodiment effect:
| Item compared | The pH value | Specific conductivity (μ s/cm) | Remarks |
| Do not use the utility model | 6.7 | 2.0 | Often change water |
| Use the utility model | 7.0 | 1.7 | Need not change water |
