Description
Technical Field
[0001] The utility model belongs to the technical field of industrial sewage treatment, and particularly relates to a cooling tower for industrial sewage treatment. Background Art
[0002] If the high-temperature wastewater discharged from industrial production is directly discharged into natural water bodies, it will cause the water body to overheat, damage the water ecological environment, cause damage to aquatic organisms, and even lead to the death of aquatic organisms and the destruction of the ecological balance. Through cooling treatment, the water temperature can be reduced, and the negative impact on aquatic organisms can be alleviated.
[0003] In a traditional sewage cooling tower, several corrugated and bent condensation pipes are installed inside an alloy tower body, and cooling water is pumped along these condensation pipes. The several corrugated and bent condensation pipes are coiled inside the tower body and communicate with each other. After the sewage enters the tower body, heat is transferred to the condensed water in the condensation pipes.
[0004] After the sewage is poured into the tower body, the cooling water is simultaneously sent into the tower body along the condensation pipes, and cooling is carried out by using the heat exchange between the sewage and the condensed water. However, the impurities in the sewage enter the tower body and are easily attached to the outer walls of these corrugated and bent condensation pipes, making it necessary to disassemble the entire condensation pipes for cleaning of the attached substances, and it is not convenient to disassemble and clean them individually. For this reason, we propose a cooling tower for industrial sewage treatment. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a cooling tower for industrial sewage treatment, which can disassemble the hollow alloy box individually for cleaning of the attached substances, close the corresponding water distribution pipes and drain pipes, and the remaining part of the cooling tower can still carry out sewage cooling work.
[0006] The technical solution adopted by the utility model is specifically as follows:
[0007] A cooling tower for industrial sewage treatment includes an alloy tower body. The upper end of the alloy tower body is of an open structure. Inside the alloy tower body, a number of hollow alloy boxes are distributed horizontally in an array. The hollow alloy boxes are all in a wavy structure. The inside of each hollow alloy box is a hollow structure. The lower surfaces of the hollow alloy boxes all abut against the lower wall of the alloy tower body. On one side of each hollow alloy box, two connecting pipes are fixedly connected in sequence from top to bottom. Along the upper edge of the alloy tower body, a number of water distribution pipes are distributed horizontally in an array. One end of each water distribution pipe extends into the alloy tower body and is connected to the adjacent connecting pipe. Along the lower edge of the alloy tower body, a number of drain pipes are distributed horizontally in an array. One end of each drain pipe extends into the alloy tower body and is connected to the adjacent connecting pipe. When treating industrial sewage, the sewage is sent into the alloy tower body from the opening. The cooling water is pumped along the water distribution pipes into the interior of each hollow alloy box. A temperature difference is formed between the inside and outside of the hollow alloy box, so that the heat of the sewage is transferred to the inside of the hollow alloy box under the action of the temperature difference and is carried away by the cooling water. Then, the cooling water leaves the hollow alloy box from the drain pipe below and finally flows out of the alloy tower body to take away the excess heat of the sewage. Finally, the tail water valve is opened to discharge the sewage. Even if impurities in the sewage adhere to the outer wall of the hollow alloy box to form attachments, the connecting pipes, water distribution pipes and drain pipes can be separated, and the hollow alloy boxes can be disassembled individually for cleaning the attachments. After closing the corresponding water distribution pipes and drain pipes, the remaining part of the cooling tower can still carry out sewage cooling work, and the cleaning interval of the attachments of the whole cooling tower is shortened.
[0008] A sealing cover is assembled at the opening of the alloy tower body. An inlet is opened on the sealing cover. Rotate the handwheel to close the sealing cover so that the alloy tower body is sealed and has a certain pressure-bearing capacity. Then open the inlet and pump sewage along the inlet to prevent sewage leakage.
[0009] Threaded sleeves are installed on the outer sides of the connecting pipes. Internal threads are provided on the inner walls of the threaded sleeves. External threads adapted to the internal threads of the threaded sleeves are provided on the outer sides of the water distribution pipes and the drain pipes. Rotate the threaded sleeve clockwise to engage with the external threads of the adjacent water distribution pipe or drain pipe to fix the connection between the connecting pipe and the adjacent water distribution pipe or drain pipe. On the contrary, rotate the threaded sleeve counterclockwise to disengage from the adjacent water distribution pipe or drain pipe, and the connection between the connecting pipe and the adjacent water distribution pipe or drain pipe can be disconnected, which is convenient for quickly disassembling the hollow alloy box.
[0010] A water inlet pipe is fixed to the outside of the alloy tower body. One end of the water inlet pipe is of a closed structure. The inside of the water inlet pipe communicates with one end of the water distribution pipe. The water distribution pipes are all connected to the cooling water source through the water inlet pipe. In this way, after starting the water pump of the cooling water source, cooling water is conveyed to each water distribution pipe along the water inlet pipe, which is convenient for distributing the cooling water into the interior of each hollow alloy box.
[0011] A return pipe is also fixed to the outside of the alloy tower body. One end of the return pipe is a closed structure. The inside of the return pipe is connected to one end of the drain pipe. The cooling water flowing out of each drain pipe converges into the return pipe and is centrally sent to the return pool for centralized heat dissipation and cooling, and then left for the water pump to transport it to the cooling water source.
[0012] Two groups of intersecting arc-shaped plates are also fixed inside the hollow alloy box. A number of arc-shaped plates in the two groups are vertically arranged in an array along both sides of the hollow alloy box respectively. The two groups of arc-shaped plates divide the internal space of the hollow alloy box into a wavy channel, which is used to extend the travel of the cooling water, facilitating the cooling water to fully absorb the heat transferred from the sewage. And the wavy channel is connected to the adjacent water distribution pipes and drain pipes, enabling the cooling water to flow smoothly.
[0013] The technical effects achieved by the present utility model are as follows:
[0014] For the cooling tower for industrial sewage treatment of the present utility model, during industrial sewage treatment, the sewage is fed into the alloy tower body from the opening. The cooling water is pumped along the water distribution pipes into the inside of each hollow alloy box. A temperature difference is formed between the inside and outside of the hollow alloy box, so that the heat of the sewage is transferred to the inside of the hollow alloy box under the action of the temperature difference and is taken away by the cooling water. Then, the cooling water leaves the hollow alloy box from the drain pipe below and finally flows out of the alloy tower body to take away the excess heat of the sewage. Finally, the tail water valve is opened to discharge the sewage. Even if impurities in the sewage adhere to the outer wall of the hollow alloy box to form attachments, the connecting pipe, water distribution pipe and drain pipe can be separated, and the hollow alloy box can be disassembled individually for cleaning the attachments. And the water distribution pipe and drain pipe belonging to it are closed, and the remaining part of the cooling tower can still carry out sewage cooling work, shortening the cleaning interval of the attachments of the entire cooling tower.

[0021] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation modes of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.
[0022] As Figures 1-4 shown, a cooling tower for industrial sewage treatment includes an alloy tower body 1. A tail water valve is installed on the lower surface of the alloy tower body 1. The upper end of the alloy tower body 1 is of an open structure. Inside the alloy tower body 1, a number of hollow alloy boxes 2 are distributed horizontally in an array. The hollow alloy boxes 2 are all in a wavy structure. The inside of the hollow alloy boxes 2 is a hollow structure. The lower surfaces of the hollow alloy boxes 2 all abut against the lower wall of the alloy tower body 1. On one side of the hollow alloy boxes 2, two connecting pipes 3 are fixedly connected in sequence from top to bottom. On the upper edge of the alloy tower body 1, a number of water distribution pipes 4 are distributed horizontally in an array. One end of the water distribution pipe 4 extends into the alloy tower body 1 and is connected to the adjacent connecting pipe 3. The other ends of the water distribution pipes 4 are all connected to a cooling water source. On the lower edge of the alloy tower body 1, a number of drain pipes 5 are distributed horizontally in an array. One end of the drain pipe 5 extends into the alloy tower body 1 and is connected to the adjacent connecting pipe 3. The other ends of the drain pipes 5 are all connected to a return water tank. First, close the tail water valve, open the cooling water source and the return water tank. When treating industrial sewage, the sewage is sent into the alloy tower body 1 from the opening. The cooling water is pumped along the water distribution pipes 4 into the interiors of the respective hollow alloy boxes 2. A temperature difference is formed inside and outside the hollow alloy boxes 2, so that the heat of the sewage is transferred to the inside of the hollow alloy boxes 2 under the action of the temperature difference and is taken away by the cooling water. Then, the cooling water leaves the hollow alloy boxes 2 from the lower drain pipes 5 and finally flows out of the alloy tower body 1, taking away the excess heat of the sewage. Since the hollow alloy boxes 2 are distributed horizontally in an array, the sewage can flow along the intervals of the hollow alloy boxes 2 along a wavy path, extending the travel. Finally, open the tail water valve to discharge the sewage. Even if impurities in the sewage adhere to the outer walls of the hollow alloy boxes 2 to form attachments, the connecting pipes 3, the water distribution pipes 4 and the drain pipes 5 can be separated, and the hollow alloy boxes 2 can be individually disassembled for cleaning the attachments, and the corresponding water distribution pipes 4 and drain pipes 5 are closed. The remaining part of the cooling tower can still carry out sewage cooling work, and the cleaning interval of the attachments of the entire cooling tower is shortened.
[0023] Among them, water pumps are installed in both the cooling water source and the return water tank, and heat dissipation fans are installed on the return water tanks. This technical solution is an existing technology and is not shown in the figure. In this way, the cooling water with heat enters the return water tank, and the heat dissipation is accelerated by the blowing of the heat dissipation fans. After the cooling water is cooled, it is transported to the cooling water source by the water pump for standby for the alloy tower body 1, forming a cooling water cycle.
[0024] As Figure 1 and Figure 2As shown, a sealing cover 6 is assembled at the opening of the alloy tower body 1. A water inlet is provided on the sealing cover 6. Rotate the handwheel to close the sealing cover 6. The handwheel of the sealing cover 6 can refer to the design of the lid of a steam tank on the market, so that the alloy tower body 1 is sealed and has a certain pressure-bearing capacity. Then open the water inlet and pump sewage along the water inlet to prevent sewage leakage.
[0025] As Figure 2 , Figure 3 and Figure 4 As shown, screw sleeves 7 are threadedly installed on the outer sides of the connecting pipes 3. Internal threads are provided on the inner walls of the screw sleeves 7. External threads adapted to the internal threads of the screw sleeves 7 are provided on the outer sides of the water distribution pipes 4 and the drain pipes 5. Rotate the screw sleeves 7 clockwise to engage with the external threads of the adjacent water distribution pipes 4 or drain pipes 5, so as to fix the connection between the connecting pipes 3 and the adjacent water distribution pipes 4 or drain pipes 5. On the contrary, rotate the screw sleeves 7 counterclockwise to disengage from the adjacent water distribution pipes 4 or drain pipes 5, and the connection between the connecting pipes 3 and the adjacent water distribution pipes 4 or drain pipes 5 can be disconnected, which is convenient for quickly disassembling the hollow alloy box 2.
[0026] As Figure 1 and Figure 2 As shown, a water inlet pipe 8 is fixed to the outside of the alloy tower body 1. One end of the water inlet pipe 8 is a closed structure, and the other end of the water inlet pipe 8 is connected and fixed to the output end of a water pump of a cooling water source. The inside of the water inlet pipe 8 communicates with one end of the water distribution pipe 4. The water distribution pipes 4 are all connected to the cooling water source through the water inlet pipe 8. In this way, after starting the water pump of the cooling water source, cooling water is conveyed to each water distribution pipe 4 along the water inlet pipe 8, which is convenient for distributing the cooling water into the interiors of the hollow alloy boxes 2.
[0027] As Figure 1 and Figure 2 As shown, a return pipe 9 is also fixed to the outside of the alloy tower body 1. One end of the return pipe 9 is a closed structure, and the other end of the return pipe 9 extends into a return water pool. The inside of the return pipe 9 communicates with one end of the drain pipe 5. The cooling water flowing out of each drain pipe 5 converges into the return pipe 9 and is centrally sent into the return water pool for centralized heat dissipation and cooling, and is left for the water pump to convey to the cooling water source.
[0028] As Figure 1 , Figure 2 and Figure 3 As shown, two groups of intersecting arc-shaped plates 10 are also fixed inside the hollow alloy boxes 2. The two groups of a number of arc-shaped plates 10 are respectively vertically arranged in an array along both sides of the hollow alloy boxes 2. The two groups of arc-shaped plates 10 divide the internal space of the corresponding hollow alloy boxes 2 into wavy channels, which extend the travel of the cooling water by using the wavy channels, facilitating the cooling water to fully absorb the heat transferred from the sewage, and the wavy channels communicate with the adjacent water distribution pipes 4 and drain pipes 5, enabling the cooling water to flow smoothly.
[0029] The working principle of the utility model is as follows: When treating industrial sewage, the sewage is fed into the alloy tower body 1 from the opening, and the cooling water is pumped along the water distribution pipe 4 into the interior of each hollow alloy box 2. A temperature difference is formed inside and outside the hollow alloy box 2, so that the heat of the sewage is transferred to the interior of the hollow alloy box 2 under the action of the temperature difference and is carried away by the cooling water. Then, the cooling water leaves the hollow alloy box 2 from the drain pipe 5 below and finally flows out of the alloy tower body 1 to carry away the excess heat of the sewage.
[0030] Meanwhile, since each hollow alloy box 2 is horizontally arranged in an array, the sewage can flow along the intervals of the hollow alloy boxes 2 along a waveform path, extending the travel distance, and finally the tail water valve is opened to discharge the sewage.
[0031] At this time, even if impurities in the sewage adhere to the outer wall of the hollow alloy box 2 to form attachments, the connecting pipe 3, the water distribution pipe 4 and the drain pipe 5 can be separated, and the hollow alloy box 2 can be disassembled individually to clean the attachments, and the corresponding water distribution pipe 4 and drain pipe 5 are closed. The remaining part of the cooling tower can still carry out sewage cooling work, and the cleaning interval of the attachments of the whole cooling tower is shortened.
[0032] The above is only the preferred embodiment of the utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented by conventional means in the art without special description and limitation.
