Description

TECHNICAL FIELD

[0001] The present application relates to the cooling equipment of industrial circulating water, specifically relates to a cooling tower. BACKGROUND

[0002] The process medium cooling or condensation in the industrial field generally uses the circulating water with lower temperature, and the circulating water needs to be evaporated and heat dissipated in the cooling tower after absorbing heat, and then is sent to the heat exchanger to absorb the heat of the process medium again. The cooling tower is divided into two categories of open heat exchange and closed heat exchange. The open heat exchange is the direct contact heat transfer between the circulating water and the air from the environment, and is also called wet air cooling. The closed heat exchange is the convective heat transfer between the circulating water in the coil and the air in the tower under the suction of the fan, and the circulating water in the closed heat exchange is isolated from the ambient air and does not directly contact with the ambient air, so it is called dry air cooling.

[0003] The existing cooling tower has the following defects: 1. The packing of the cooling tower usually needs to be replaced once every three years. The existing packing replacement is to manually remove the old packing in the tower and then place the new packing in the tower body. This maintenance and replacement method not only has large labor intensity, but also consumes a long time. The long replacement operation affects the normal operation of the production equipment. 2. The existing cooling tower forms a water circulation refrigeration mode between the cooling tower and the refrigerated device, and the cooling water in the tower is in a one-way non-circulation refrigeration mode. Therefore, the heat exchange effect is not good, the heat exchange efficiency is not high, and some cooling towers even waste water resources. SUMMARY

6. The high and low temperature cooling and wet and dry air cooling modular cooling tower according to claim 5 is characterized in that: The cooling tower body is provided with a plurality of cooling fans, and a plurality of cooling fans are provided at the bottom of the cooling tower body, and a plurality of cooling fans are provided at the bottom of the cooling tower body. An auxiliary fan is provided at the air-assisting inlet; a cold water trough is provided on the bottom surface of the water collecting tank, and one end of the circulating water delivery pipe extends into the cold water trough, and the cold water trough is located directly below the low-temperature integrated dry-wet air cooling module; the hollow left water supply plate and the hollow right water supply plate in the lowest dry-wet air cooling unit of the high-temperature integrated dry-wet air cooling module are connected to the drainage end of the water pump A through a branch pipe, and the water inlet end of the water pump A is connected with one end of the delivery pipe, and the other end of the delivery pipe extends into the circulating water return pool. Under the action of the water pump A, the circulating water in the circulating water return pool flows into the left front cavity of the hollow left water supply plate and the right front cavity of the hollow right water supply plate in the lowest dry-wet air cooling unit through the delivery pipe. The left front cavity and the right The circulating water in the front cavity flows into the hollow front water distribution plate in the lowest dry and wet air cooling unit, and the circulating water in the hollow front water distribution plate flows to the hollow rear water distribution plate through the hollow filler plates in the lowest dry and wet air cooling unit. The circulating water in the hollow rear water distribution plate flows into the left rear cavity of the hollow left water supply plate and the right rear cavity of the hollow right water supply plate in the lowest dry and wet air cooling unit. The circulating water in the left rear cavity and the right rear cavity flows to the dry and wet air cooling unit on the upper layer through the guide vertical pipe. After flowing through each dry and wet air cooling unit, the circulating water flows to the water distribution frame in the spray module through the branch vertical pipe. The circulating water in the water distribution frame is sprayed downward from the sprinkler head to the dry and wet air cooling unit through each horizontal water distribution pipe and the longitudinal water distribution pipe. The circulating water is sequentially discharged from each layer The water flows into the gaps between the hollow filler plates of the dry and wet air cooling units and falls downward into the area outside the cold water tank in the water collection pool; the hollow left water supply plate and the hollow right water supply plate in the dry and wet air cooling unit of the lowest layer of the low-temperature integrated dry and wet air cooling module are connected to the drainage end of the water pump B through a branch pipe, and the water inlet end of the water pump B is connected to one end of the delivery water pipe, and the other end of the delivery water pipe extends into the area outside the cold water tank in the water collection pool. Under the action of the water pump B, the circulating water in the area outside the cold water tank in the water collection pool flows through each layer of dry and wet air cooling units in turn through the delivery water pipe, is sprayed out through the spray module, and then flows downward through the gaps between the hollow filler plates of the dry and wet air cooling units of the next layer, and falls downward into the cold water tank in the water collection pool.

7. The high and low temperature cooling and wet and dry air cooling modular cooling tower according to claim 6 is characterized in that: The high-temperature integrated dry-wet air cooling module and the low-temperature integrated dry-wet air cooling module are respectively arranged on pulley A and pulley B, and the pulley A and pulley B are respectively arranged on slide rails A and slide rails B, and the slide rails A and slide rails B span the water collection pool. Inspection doors A and inspection doors B are respectively provided on the side walls of the horizontal cooling tower body and opposite to the slide rails A and slide rails B. Transfer platforms A and transfer platforms B are respectively provided outside the horizontal cooling tower body and at the inspection doors A and inspection doors B. By opening the inspection doors A and inspection doors B, pulleys A and pulley B can be moved out to the transfer platforms A and transfer platforms B outside the horizontal cooling tower body respectively.

8. The high and low temperature cooling and wet and dry air cooling modular cooling tower according to claim 7 is characterized in that: An air filter is provided at the air outlet.
