The cooling water system has the beneficial effects that not only can the working efficiency of the vacuum pump and the economic efficiency of a unit be improved, but also air conditioning chilled water is reasonably utilized, and water resources are saved.
Description
Technical field
The utility model relates to a kind of cooling water system, particularly a kind of cooling water system that is applied in Nash hytor.
Background technique
Nash hytor has that rate of air sucked in required is large, energy consumption is little, water quality loss less, safe and reliable, automaticity advantages of higher, therefore in large-size thermal power plant, be used widely.Appropriate water is housed as working water in the pump housing of Nash hytor, in the time of vane rotary, water is thrown to surrounding by impeller, due to the effect of centrifugal force, water formed one with the closed circle of the approximate uniform thickness of pump chamber shape, between impeller hub and water ring, form some loculuses, Nash hytor is realized the function of air-breathing, compression and exhaust by the variation of pump chamber.The exhaust capacity of Nash hytor directly affects the aggregation extent of air in vapour condenser, and the exhaust capacity of Nash hytor is mainly subject to the impact of working water temperature.
In thermal power plant, the main frame recirculated cooling waters that adopt carry out the working water in coolant pump more at present, but when unit is in the time that summer condition moves, because summer environment temperature is high, main frame Inlet Temperature of Circulating Water can reach 33 DEG C, still adopt this cooling means effect generally very poor, add wasted work and the interior gas/vapour mixture heat transmission of vapour condenser of pump rotation, the general superelevation of temperature of working water, cause the exhaust capacity degradation of Nash hytor, air is accumulated in vapour condenser, cause the degree of vacuum of vapour condenser to decline, thereby have a strong impact on the heat-economy of unit.
Model utility content
The utility model technical issues that need to address are to provide a kind of cooling water system that is applied to Nash hytor, to ensure that the working water that enters Nash hytor keeps lower temperature, further improve exerting oneself of vacuum pump, improve Unit Economic benefit.
For addressing the above problem, technical solution adopted in the utility model is:
Nash hytor cooling water system, the water intake of described Nash hytor is communicated with the water outlet of steam-water separator by working water pipeline, on described working water pipeline, be provided with the heat exchanger for cooling steam-water separator water, the intake pipe that is communicated with heat exchanger water intake is communicated with central air-conditioning freezing water water storage tank by the first arm, and the water return pipeline that is communicated with heat exchanger water outlet is communicated with wet pit by the second arm.
Improvement of the present utility model is: the intake pipe of described connection heat exchanger water intake is communicated with main frame circulating water water storage tank by the 3rd arm, and the water return pipeline that is communicated with heat exchanger water outlet is communicated with wet pit by the 4th arm.
Improvement of the present utility model: be respectively arranged with on described the first arm, the second arm, the 3rd arm and the 4th arm and control the switch valve that arm turns on and off.
The beneficial effect that adopts technique scheme to produce is:
The utility model adopts heat exchanger to carry out heat exchange to steam-water separator water, in heat exchanging process, adopt central air-conditioning freezing water as heat transferring medium, the working water temperature that enters Nash hytor can be controlled between 7 ~ 12 DEG C, reach the object that reduces operating water of vacuum pump temperature, not only can improve the working efficiency of vacuum pump and the economic benefit of unit, but also rationally utilized air conditioning water, save water resources.
Brief description of the drawings

Wherein: 1. Nash hytor, 2. steam-water separator, 3. working water pipeline, 4. heat exchanger, 5. intake pipe, 6. water return pipeline, 7. the first arm, 8. central air-conditioning freezing water water storage tank, 9. the second arm, 10. wet pit, 11. the 3rd arms, 12. main frame circulating water water storage tanks, 13. the 4th arms, 14. switch valves.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of Nash hytor cooling water system, its structure as shown in Figure 1, the water intake of Nash hytor 1 is communicated with the water outlet of steam-water separator 2 by working water pipeline 3, steam-water separator 2 is to Nash hytor transportation work water, but under summer condition, due to steam-water separator working water excess Temperature out, can greatly reduce the working efficiency of Nash hytor, therefore in working water pipeline, add heat exchanger, for reducing the temperature that enters Nash hytor working water, to improve the working efficiency of Nash hytor.
In the utility model, heat exchanger 4 is arranged on working water pipeline 3, and the intake pipe 5 that is communicated with heat exchanger water intake is communicated with central air-conditioning freezing water water storage tank 8 and main frame circulating water water storage tank 12 by the first arm 7 and the 3rd arm 11 respectively; The water return pipeline 6 that is communicated with heat exchanger water outlet is communicated with wet pit 10 by the second arm 9 and the 4th arm 13 respectively.On the first arm, the second arm, the 3rd arm and the 4th arm, be respectively arranged with switch valve 14, connect and turn-off for controlling arm.
In the time of summer condition, open the switch valve on the first arm and the 3rd arm, close the switch valve on the second arm and the 4th arm, use cooling water that in central air-conditioning freezing water water storage tank, temperature is lower to the working water processing of lowering the temperature; And in the winter time when operating mode, close the switch valve on the first arm and the 3rd arm, and open the switch valve on the second arm and the 4th arm, use cooling water that temperature in main frame circulating water water storage tank is higher to the working water processing of lowering the temperature.
