As shown in fig. 1 and 2, an embodiment of the present utility model provides a cooling tower 100, wherein the cooling tower 100 includes a tower body 10, a water inlet pipe 20, a shaft 30, an overflow well 40, a water collecting tank, a water outlet pipe 50, a filler and spray assembly.
The inlet tube 20 is connected between steam turbine and shaft 30, and the catch basin sets up in the bottom of tower body 10, and shaft 30 and overflow well 40 all set up in tower body 10 along vertical direction, and overflow well 40 and packing all are located the top of catch basin, spray assembly outlet pipe 50 and connect between catch basin and steam turbine.
The cooling tower includes a circulation state and a spray state.
When the cooling tower is in a circulating state, the top end of the vertical shaft 30 is communicated with the top end of the overflow well 40, and the vertical shaft 30 is separated from the spraying assembly; when the cooling tower is in a spraying state, the vertical shaft 30 is communicated with the spraying assembly, and the spraying assembly can guide cooling water output by the vertical shaft 30 to flow to the filler.
It should be explained that, after the cooling water cools the turbine, the water temperature rises, the cooling water with the rising water temperature flows into the shaft 30 through the water inlet pipe 20, then flows back to the water collecting tank through the well or flows through the spray assembly and back to the water collecting tank, the temperature of the cooling water flowing back to the water collecting tank drops, and finally flows back to the turbine from the water outlet pipe 50 to cool the turbine.
With the cooling tower, if the temperature of the cooling water is low during winter operation, the cooling tower can be in a circulating state, the cooling water directly returns to the water collecting tank without the filler, and then returns to the steam turbine for heating through the water outlet pipe 50. After the temperature of the cooling water rises, the cooling tower can be switched to a spraying state, the cooling water flows to the filler through the spraying assembly, then flows through the filler to cool and drop to the water collecting tank, and finally returns to the steam turbine through the water outlet pipe 50. The cooling water can directly return to the water collecting tank through the overflow well 40 when the temperature of the cooling water is low, so that the cooling water is prevented from contacting with the filler, and the phenomenon of icing caused by the cooling water flowing through the filler is avoided, and the phenomenon of ice hanging and breaking of the filler due to the formation of ice under the filler is avoided.
In some embodiments, the spray assembly includes a water distribution member 60, the water distribution member 60 being disposed above the packing and connected to the shaft 30.
The water distribution member 60 can communicate with the shaft 30 to guide the cooling water outputted from the shaft 30 to the packing when the cooling tower is in a spray state.
In some embodiments, the packing includes a plurality of partitions 11, and the spray assembly includes a plurality of water distribution members 60, each water distribution member 60 being connected between the shaft 30 and a corresponding one of the partitions 11 to direct the flow of cooling water to the corresponding partition 11.
In practical application, the plurality of partitions 11 include a plurality of outer regions and a plurality of inner regions, the plurality of outer regions being disposed around the plurality of inner regions.
Specifically, in the embodiment shown in FIG. 1, the packing includes four inner regions and eight outer regions.
In some embodiments, the cooling tower includes a first gate 70 assembly disposed between the shaft 30 and the plurality of water distribution members 60 for communicating with and blocking the shaft 30 from any of the water distribution members 60. In this manner, the number of water distribution members 60 in communication with the shaft 30 may be controlled by the first gate 70 assembly to effect the adjustment of the temperature of the cooling water in the sump.
It should be explained that the cooling water will be cooled when flowing through the filler, and the more the subareas 11 are flowing through, i.e. the larger the flowing area is, the better the cooling effect is. However, in winter, since the water temperature is low, in order to avoid freezing due to excessive water temperature decrease, it is possible to let the cooling water not flow through the packing or through the partial section 11 of the packing when the water temperature is low. After the water temperature has risen, the cooling water is gradually let to flow through more sections 11 and finally through all sections 11 of the filling.
In practice, the first gate 70 assembly includes a plurality of first gates 70, and each first gate 70 is disposed between the shaft 30 and a corresponding water distribution member 60 to communicate and block the shaft 30 and the corresponding water distribution member 60.
In some embodiments, the cooling tower includes a plurality of shafts 30 and a plurality of overflow wells 40, wherein the plurality of shafts 30 are spaced apart in the tower body 10, and each overflow well 40 is connected to a corresponding shaft 30. In this way, the cooling water outputted from each shaft 30 can flow back to the sump through the overflow well 40 connected thereto while the cooling tower is in a circulating state.
In practical application, the water distribution members 60 are divided into a plurality of groups, and each group of water distribution members 60 is connected to a corresponding shaft 30.
As shown in fig. 1, the packing includes twelve partitions 11, corresponding to which twelve water distribution members 60 are provided, and the number of the shafts 30 is four, and each shaft 30 is connected with three water distribution members 60 to deliver the cooling water outputted therefrom to two outer and one inner regions adjacent thereto.
In some embodiments, the spray assembly further comprises a spray pipe 80 and an anti-freezing pipe, the spray pipe 80 is disposed at the top of the tower body 10 for spraying the edge of the tower body 10, and the anti-freezing pipe is connected between the vertical shaft 30 and the spray pipe 80.
The spraying states comprise an antifreezing state, a first spraying state and a second spraying state.
When the cooling tower is in an antifreezing state, the vertical shaft 30 is communicated with the antifreezing pipe, and the vertical shaft 30 is separated from the water distribution piece 60; when the cooling tower is in the first spraying state, the vertical shaft 30 is simultaneously communicated with the anti-freezing pipe and the water distribution piece 60; when the cooling tower is in the second spraying state, the vertical shaft 30 is communicated with the water distribution member 60, and the vertical shaft 30 is separated from the antifreeze pipe.
It should be explained that, when the temperature is lower in winter, the edge of the tower body 10 is more likely to be frozen, so that after the water temperature is raised, the cooling tower can be switched from the circulation state to the anti-freezing state, and the cooling water flows to the spray pipe 80 through the anti-freezing pipe and then is sprayed to the edge of the tower body 10 through the spray pipe 80 for deicing.
When the cooling tower is in an antifreezing state, the temperature of the cooling water can remove the freezing at the edge of the tower body 10, but is still lower, so that the cooling water does not flow through the filler, ice hanging is avoided from being formed below the filler, and excessive temperature reduction of the cooling water caused by flowing through the filler can be avoided. In addition, the cooling water output from the shaft 30 can also flow into the sump through the overflow well 40.
It will be appreciated that when the packing includes a plurality of partitions 11 as described above, the first spraying state includes a plurality of sub-states, and when in the different sub-states, the number of water distributors 60 communicating with the shaft 30 is different, and the number of partitions 11 through which the cooling water flows is also different.
Taking the embodiment shown in fig. 1 as an example, the first spray state includes 9 sub-states.
When the cooling tower is in the first sub-state, the vertical shaft 30 is simultaneously communicated with the antifreeze pipe and a water distribution piece 60, and cooling water flows through an outer region of the filler; when the cooling tower is in the second sub-state, the vertical shaft 30 is simultaneously communicated with the anti-freezing pipe and the two water distribution pieces 60, and cooling water flows through the two outer areas of the filler; similarly, when the cooling tower is in the eighth sub-state, the vertical shaft 30 is simultaneously communicated with the antifreeze pipe and the eight water distribution pieces 60, and the cooling water flows through the eight outer areas of the filler; when the cooling tower is in the ninth sub-state, the shaft 30 is simultaneously in communication with the antifreeze pipes and twelve water distributors 60, and cooling water flows through all the sections 11 of the packing.
In connection with the above, it will be appreciated that as the temperature of the cooling water increases, the cooling tower may be sequentially switched from the first sub-state to the ninth sub-state, i.e. progressively opening more sections 11 of the packing, until the cooling water is caused to flow through all sections 11 of the packing.
In some embodiments, the spray pipe 80 extends along the circumferential direction of the tower body 10, and the spray pipe 80 is provided with a plurality of spray holes, and the plurality of spray holes are arranged on the spray pipe 80 at intervals along the circumferential direction of the tower body 10, that is, the extending direction of the spray pipe 80.
In practice, the shower pipe 80 is an annular pipe.
In some embodiments, the antifreeze pipes include a plurality of antifreeze pipes, each connected between the shower pipe 80 and a corresponding one of the shafts 30.
In the embodiment shown in fig. 1, the number of antifreeze pipes is four. And in fig. 2, the antifreeze tube is located below the water distribution member 60.
In some embodiments, the cooling tower further includes a second gate 90 assembly disposed between the shaft 30 and the antifreeze pipe for communicating and isolating the shaft 30 and the antifreeze pipe.
In practical application, the second gate 90 assembly includes a plurality of second gates 90, and each second gate 90 is disposed between a corresponding antifreeze pipe and the vertical shaft 30, for communicating and blocking the vertical shaft 30 and the antifreeze pipe.
It should be noted that the second shutter 90 is normally opened or closed synchronously.
In order to facilitate understanding of the technical solution of the present utility model, the technical solution of the foregoing embodiment is described herein with reference to fig. 1:
when starting in winter, all the first gates 70 and the second gates 90 are closed, at this time, the nuclear power station starts two circulating water pumps to drive 67% of the total water to circulate, and the circulation paths are a steam turbine, a water inlet pipe 20, a vertical shaft 30, an overflow well 40, a water collecting tank, a water outlet pipe 50 and a steam turbine in sequence. The temperature can be raised under the action of the steam turbine in the circulating process of the cooling water, and the cooling tower is in a circulating state.
When the temperature of the cooling water is greater than or equal to 25 ℃, all the second gates 90 are opened, part of the cooling water output by the shaft 30 is conveyed to the spray pipe 80 through the antifreeze pipe, then the edge of the branch tower body 10 is sprayed from the spray pipe 80 and finally flows into the water collecting tank, and the other part of the cooling water can flow into the water collecting tank through the overflow well 40. At this time, the cooling tower is in an antifreezing state.
After the cooling tower is in an antifreezing state for a period of time, the temperature of the cooling water continuously rises. When the temperature of the cooling water is greater than or equal to 50 degrees celsius, a first shutter 70 is opened, and the cooling water may flow through a partition 11 of the packing and be an outer region of the packing. The cooling tower is then in a first sub-state in the first spray state.
If the temperature of the cooling water drops below 25 degrees celsius after the cooling tower is in the first sub-state for a period of time, the first gate 70 is closed and the cooling tower returns to the freeze-protected state. If the water temperature satisfies the opening condition, the second first shutter 70 is opened. This is repeated until all of the first shutters 70 are opened.
After all the first gates 70 are opened, all the second gates 90 can be closed without a decrease in water temperature, and the cooling water output from the shaft 30 flows through all the partitions 11 of the packing, and the cooling tower is in the second spraying state.
In addition, when the cooling tower is operated in winter, if the water temperature is too low, the second shutter 90 needs to be opened to bring the cooling tower into the first spraying state, and if the water temperature is further reduced, the first shutter 70 may be gradually closed, and the first shutter 70 controlling the flow of cooling water through the inner region of the packing may be closed first.
It should be noted that the above water temperature refers to the temperature of the cooling water flowing through the filler and dropping into the water collecting tank, and the opening condition is that the water temperature is greater than or equal to [19+5/34× (4-T) ] celsius, wherein T is the ambient temperature.
Similarly, it should be explained that if the water temperature is lowered after the plurality of first shutters 70 are opened, when it is necessary to gradually close the first shutters 70, the condition for closing the next first shutter 70 is that the water temperature is less than or equal to [9+5/34× (4-T) ] celsius.
It will be appreciated that closing the next first shutter 70 as described above does not include opening only one first shutter 70. The opening of the first shutter 70 is still performed as described in the above embodiment.
Of course, it should be further noted that when the water temperature is too low, in this embodiment, the alarm processing is performed when the water temperature is less than or equal to [8+5/34× (4-T) ] celsius. While the water temperature is continuously reduced and the water temperature is less than or equal to [7+5/34× (4-T) ] deg.c, one first shutter 70 may be directly closed in order to protect the entire cooling tower, and the number of openings of the first shutter 70 at this time (except for the first shutter 70 which is not opened) is not considered.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
