Description

Technical Field

[0001] The present invention relates to the technical field of cooling auxiliary equipment for thermal power units, and particularly to an intelligent cooling water circulation device for thermal power units. Background Art

[0002] A thermal power unit, namely a coal-fired condensing unit, generates heat energy by burning fuels such as coal, heats water into steam to drive the steam turbine to rotate, and then drives the generator to generate electricity. During the operation of the thermal power unit, the cooling water circulation plays a key role. It is mainly responsible for cooling the exhaust steam of the steam turbine, condensing the steam into water in the condenser, and realizing the recycling of water resources. During this process, the cooling water will absorb a large amount of heat, resulting in a temperature rise. To maintain the cooling effect, the circulating water system will transport the heated cooling water to a cooling tower or other cooling devices for cooling treatment, and then recycle it. However, some current cooling water circulation devices have obvious defects, that is, they cannot adjust the cooling degree of the cooling water according to actual needs, but always operate at a fixed cooling efficiency. This not only causes waste of electric power resources but also has an adverse impact on the environment. Therefore, improving the cooling water circulation device to achieve flexible adjustment of the cooling degree is of great significance for improving the operation efficiency of thermal power units, saving electric power resources, and promoting environmental protection. In response to the above problems, there may already be technical means to solve them in the prior art, but this case wants to provide an alternative or replacement technical solution. Summary of the Invention

[0003] The technical solution of the present invention to achieve the above object is: an intelligent cooling water circulation device for thermal power units, including: a cooling housing, a water filtration housing, and a pair of cooling housing support legs. The pair of cooling housing support legs are respectively installed on the cooling housing. A return water coarse filtration structure is installed on the water filtration housing. A funnel-shaped cooling structure is installed in the cooling housing. The funnel-shaped cooling structure includes: a convex air guide housing, a top isolation net, a heat-conducting blower fan, and a return water sump. The convex air guide housing is installed on the cooling housing. The top isolation net is installed on the convex air guide housing. The heat-conducting blower fan is installed in the convex air guide housing. The return water sump is installed on the cooling housing. A funnel-shaped distributed cooling assembly is installed in the cooling housing. It should be noted that in the above, through the lock flange provided on the lowering support leg, the entire device can be locked in place on the ground. The hot water passing through the unit will be filtered by the return water coarse filtration structure on the water filter housing and then transported into the cooling housing. In the cooling housing, heat dissipation is carried out by the funnel-shaped distributed cooling component. The hot air will be sucked by the heat-conducting blower fan and released to the outside through the top isolation net from the raised air guide housing. The cooled water will fall into the return water sump under the action of gravity and then be re-input into the thermal power unit through the cold water delivery pipe to continue the cooling operation. The temperature sensor provided in the raised air guide housing can conveniently monitor the temperature inside the cooling housing.

[0004] Preferably, the funnel-shaped distributed cooling component includes: a plurality of exchange air guide net plates, a plurality of fan installation frames, a plurality of in-shell cooling fans, a through-installed hollow layer, a temperature-conducting copper funnel, a plurality of first extended water receiving rings, a through-installed hollow cone, a plurality of second extended water receiving rings, a transfer water sump, a water delivery ring, a water injection pipe, a water injection pump, and a cold water delivery pipe; A plurality of the exchange air guide net plates are respectively installed in the cooling housing, a plurality of the fan installation frames are respectively installed in the cooling housing, a plurality of the in-shell cooling fans are respectively installed in the fan installation frames, the through-installed hollow layer is installed in the cooling housing, and the through-installed hollow layer is respectively connected to a plurality of the fan installation frames. The temperature-conducting copper funnel is installed in the cooling housing, and the temperature-conducting copper funnel is inserted into the through-installed hollow layer. A plurality of the first extended water receiving rings are respectively installed on the temperature-conducting copper funnel. The through-installed hollow cone is installed in the cooling housing, and a plurality of the second extended water receiving rings are respectively installed on the through-installed hollow cone. The transfer water sump is installed on the cooling housing, and the transfer water sump is connected to the water delivery ring. The water delivery ring is sleeved on the raised air guide housing, and the water delivery ring is connected to the water injection pipe. The water injection pipe is connected to the water injection pump, and the cold water delivery pipe is connected to the return water sump; It should be noted that in the above, hot water is sucked by the water injection pump and injected into the water injection pipeline. Through the release of the water delivery ring, it falls into the transfer water sump, and then from the transfer water sump to a plurality of second extended water receiving rings and a plurality of first extended water receiving rings below. Heat will be conducted to the permeable placement hollow cone and the temperature guiding copper funnel through the plurality of second extended water receiving rings and the first extended water receiving rings respectively. At the same time, the internal cooling fans in the plurality of fan placement frames will be driven, so that the outside air is sucked in from a plurality of exchange air guiding net plates on the cooling housing and blows on the permeable placement hollow layer. Then, through a plurality of air inlets arranged on the temperature guiding copper funnel, the heat enters the permeable placement hollow cone from the air inlets of the temperature guiding copper funnel. Since the permeable placement hollow cone is a hollow porous structure, the hot air will blow upward through the center of the cooling housing until it blows to the outside from the top isolation net. The cold water that has completed heat dissipation then falls into the return water sump and is transported to the unit by the cold water delivery pipe for continuing to cool the unit.

A pair of the door connection blocks are respectively connected to a pair of push-and-open components, the S-shaped transfer water pipe is connected to the water filtration housing, and the S-shaped transfer water pipe is connected to the water injection pump; It should be noted that in the above, the hot water flowing out of the unit is transported out of the unit by the hot water delivery pipe, sucked and pressurized by the return water transport pump, pumped into the return water elevation pipe, flows through the return water solenoid valve, and then flows into the water filtration housing. After being filtered by the waste water filter plate, it falls to the bottom of the water filtration housing and is then transported to the water injection pump through the S-shaped transfer water pipe.

At this time, the housing rubber sealing layer flips outward. At the same time, the return water solenoid valve closes and stops the return water elevation pipeline. At this time, the worker can clean the impurities deposited on the waste water filter plate. After the cleaning is completed, the return water solenoid valve restores the flow of the return water elevation pipeline, and then the pair of telescopic air rods contract. At this time, the air rod pushing block pulls the air rod pushing block and the door body connecting block, so that the closed hatch is pulled again and flipped back to its original position. The housing rubber sealing layer plays a sealing role. The flow rate sensor arranged in the water filter housing can specifically estimate and monitor the capacity of the accumulated water in the water filter housing, which is convenient for controlling the water supply volume to the cooling housing. The observation porthole arranged on the water filter housing can observe and evaluate the amount of impurities accumulated on the waste water filter plate in the water filter housing, so as to clean and maintain the waste water filter plate in time.

[0019] According to the appendix Figures 1-7It is concluded that the entire device can be locked in place on the ground through the lock flange provided on the lowering support leg 3. The hot water passing through the unit will be filtered by the return water coarse filtration structure on the water filter housing 2 and then transported into the cooling housing 1. The funnel-shaped distributed cooling component in the cooling housing 1 dissipates heat. The hot air will be sucked by the heat-conducting blower fan 6 and released to the outside through the raised air guide housing 4 via the top isolation net 5. The cooled water will fall into the return water sump 7 under the action of gravity and then be re-introduced into the thermal power unit through the cold water delivery pipe 20 for continuous cooling operation. The temperature sensor provided in the raised air guide housing 4 can facilitate the monitoring of the temperature in the cooling housing 1. The hot water is sucked by the injection water pump 19 and injected into the injection water pipe 18. Through the release of the water delivery ring 17, it falls into the transfer water sump 16 and then from the transfer water sump 16 to the multiple second extended water receiving rings 15 and multiple first extended water receiving rings 13 below. The heat will be conducted to the permeable placement hollow cone 14 and the temperature-conducting copper funnel 12 through the multiple second extended water receiving rings 15 and the first extended water receiving rings 13 respectively. At the same time, the in-shell cooling fans 10 in the multiple fan placement frames 9 will be driven, so that the outside air is sucked into the cooling housing 1 through the multiple exchange air guide net plates 8 on the cooling housing 1, blown on the permeable placement hollow layer 11, and then through the multiple air inlets provided on the temperature-conducting copper funnel 12, the heat enters the permeable placement hollow cone 14 from the air inlets of the temperature-conducting copper funnel 12. Since the permeable placement hollow cone 14 is a hollow porous structure, the hot air will blow upward through the center of the cooling housing 1 until it blows to the outside through the top isolation net 5. The cold water after heat dissipation falls into the return water sump 7 and is then transported to the unit by the cold water delivery pipe 20 for continuous cooling of the unit.

After the cleaning is completed, the return water solenoid valve 24 restores the flow of the return water elevation pipeline 23, and then the pair of telescopic air rods 35 contract. At this time, the air rod pushing block 32 pulls the air rod pushing block 32 and the door body connecting block 29, so that the closed hatch 27 is pulled again and flipped back to its original position. The housing rubber sealing layer 26 plays a sealing role. The flow rate sensor provided in the water filter housing 2 can specifically estimate and monitor the capacity of the accumulated water in the water filter housing 2, which is convenient for controlling the water supply volume to the cooling housing 1.
