Description

Technical Field

[0001] This utility model relates to an open cooling tower, specifically a partitioned evaporative cooling tower. Background Technology

[0002] Open cooling towers transfer heat through direct contact between water and air. Hot water is sprayed down from the top of the tower, making full contact with the air flowing upwards from the bottom. During this contact, some of the water evaporates, and the evaporated water vapor absorbs a large amount of heat, thus lowering the temperature of the remaining water.

[0003] Airflow is achieved through the fans in the cooling tower. The fans are usually installed at the top of the cooling tower. By rotating, they generate negative pressure, drawing air upwards from the bottom of the tower, allowing the air to come into full contact with the water and carrying away heat.

[0004] Existing cooling towers typically utilize direct heat exchange between outside air and the hot water to be cooled. However, when the outside air temperature is high, the cooling effect of the hot water after heat exchange is limited, making it difficult to reach the temperature required for actual use, thus affecting the cooling efficiency. Utility Model Content

[0005] In order to solve the problems in related technologies, this utility model provides a partition wall evaporative cooling tower, which solves the problem of limited cooling effect of existing cooling towers.

[0006] To solve the above problems, the following technical solutions are provided:

[0007] A partition wall evaporative cooling tower includes a body with evaporative cooling packing; characterized in that a gas precooling chamber is provided on the outer wall surface of the body corresponding to the air inlet, an opening is provided on the side wall surface of the gas precooling chamber near the air inlet, the opening corresponds to the position of the air inlet, a first air inlet hole is provided on the side wall surface of the gas precooling chamber away from the air inlet, and a partition wall heat exchange mechanism is provided in the gas precooling chamber between the first air inlet hole and the air inlet.

[0008] The air inlet and air outlet of the partition wall heat exchange mechanism correspond to the positions of the first air inlet hole and the air inlet, respectively. The top and bottom of the partition wall heat exchange mechanism have spray water inlet and spray water outlet, respectively.

[0009] The gas precooling chamber above the partition-type heat exchanger has a cooling water spray mechanism; and a second air inlet.

[0010] Through the above technical solution, by setting up a gas precooling chamber, when the air humidity in the external environment is low, the cooling water spray mechanism is turned off, allowing the lower temperature air to directly enter the body for cooling; when the temperature in the external environment is too high, the cooling water spray mechanism of the gas precooling chamber is turned on, and the air entering the body is precooled through the heat exchange between the cooling water and the hot air, thereby reducing the temperature of the air entering the body and significantly improving the cooling effect of the hot water to be cooled.

[0011] With the second air inlet, when the gas temperature entering the gas precooling chamber is too high, it enters the partition heat exchanger through the first air inlet and exchanges heat with the spray water. The water temperature falling from the partition heat exchanger rises. At this time, the first fan opens to draw air from the gas precooling chamber, so that the gas entering from the second air inlet comes into direct contact with the water falling from the partition heat exchanger. The spray water undergoes a phase change, its temperature drops, and it falls into the water collection tank for subsequent cooling circulation. This process ensures that the water sprayed by the cooling water spraying mechanism onto the partition heat exchanger is always at a low temperature, thus continuously providing a highly efficient cooling effect for the medium to be cooled.

[0012] Furthermore, a water collection tank is provided at the bottom of both the main body and the gas precooling chamber. The water collection tank in the gas precooling chamber is located below the second air inlet, and the water collection tank of the main body is located below the air inlet. A medium flow outlet is provided on the side wall of the main body corresponding to the water collection tank of the main body.

[0013] The cooling water spraying mechanism includes a water pump, a liquid-conducting pipe, and multiple first spray pipes. The inlet of the water pump is connected to a pumping pipe, and the other end of the pumping pipe is connected to the water collection tank. The outlet of the water pump is connected to an outlet pipe, which is vertically arranged. The other end of the outlet pipe extends into the gas precooling chamber and is connected to the liquid-conducting pipe. The liquid-conducting pipe is arranged along the width direction of the gas precooling chamber, and both ends of the liquid-conducting pipe are sealed. One end of each first spray pipe is connected to the liquid-conducting pipe. Each first spray pipe is arranged along the length direction of the gas precooling chamber, and the other end of each first spray pipe is sealed. Each first spray pipe is equipped with multiple first spray heads, and each first spray head is located above the partition wall heat exchange mechanism.

[0014] Through the above technical solution, by setting multiple first spray heads, cooling water can be evenly sprayed from the water collection tank onto the surface of the heat exchange mechanism. This uniform spraying method significantly improves the uniformity of heat exchange between cooling water and hot air, thereby effectively improving the cooling efficiency of hot air.

[0015] Furthermore, the partition wall heat exchange mechanism includes multiple sets of heat exchange components, each set of heat exchange components includes two heat exchange plates arranged in sequence, with a gap between adjacent heat exchange plates;

[0016] Each heat exchange assembly has a first sealing plate at the top and bottom between two heat exchange plates. The front and rear ends of the two heat exchange plates in each heat exchange assembly are open, forming the air inlet and air outlet.

[0017] In two adjacent heat exchange components, the front and rear ends of the two heat exchange plates that are close to each other are equipped with second sealing plates. The top and bottom of the two heat exchange plates that are close to each other in two adjacent heat exchange components are open, forming the spray water inlet and the spray water outlet.

[0018] With the above technical solution, the spray water enters from the spray water inlet and exits from the spray water outlet through the setting of the first sealing plate and the second sealing plate, and the air enters from the air inlet and exits from the air outlet. The spray water and the air do not come into direct contact, but heat exchange is achieved, so that the air entering the body is cold and dry air. When the cold and dry air comes into direct contact with the medium falling from the packing layer, it can absorb more heat from the medium through evaporation, thereby ensuring the cooling effect.

[0019] Furthermore, the main body includes a tower body, a packing layer is provided in the tower body above the air inlet, and a hot water spraying mechanism for spraying hot water onto the packing layer is provided in the tower body above the packing layer; the hot water spraying mechanism includes a plurality of second spray pipes, which are evenly distributed along the width direction of the tower body, and each second spray pipe is arranged along the length direction of the tower body, and a plurality of second spray heads are arranged along the length direction of each second spray pipe.

[0020] Through the above technical solution, the hot water to be cooled can be evenly sprayed onto the packing layer by setting the second spray head, ensuring that the hot water and cold air are in full and uniform direct contact, thereby achieving efficient heat exchange and significantly improving the cooling effect.

[0021] Furthermore, the side wall of the gas precooling chamber below the opening is sealed; a first fan is provided at the top of the gas precooling chamber, and a second fan is provided at the top of the tower body.

[0022] Furthermore, a first water collector is provided in the gas precooling chamber, and the first water collector is located above the first spray pipe; a second water collector is provided in the tower body above the second spray pipe.

[0023] Through the above technical solution, by setting up a first water collector and a second water collector, the first fan and the second fan will extract the air from the gas precooling chamber and the main body. However, in the gas precooling chamber and the main body, the air and water are in direct contact and exchange heat, resulting in the air containing a large number of water droplets. At this time, the first water collector and the second water collector can separate the water droplets from the air before the air is discharged from the gas precooling chamber and the main body, thereby reducing water loss, ensuring the long-term stable operation of the gas precooling chamber, and reducing the loss of the medium to be cooled.

[0024] Furthermore, there are two air inlets, and gas precooling chambers are provided on both side walls of the main body corresponding to the two air inlets.

[0025] By using the above technical solution and setting up two gas precooling chambers, the gas flow rate entering the main body can be significantly increased and the gas temperature entering the main body can be reduced. After the cold air and hot water exchange heat, the cooling range of the hot water can be effectively improved, thereby ensuring the stability of the cooling effect.

[0026] The above solution has the following advantages:

[0027] 1. By setting up a gas precooling chamber, when the ambient air humidity is low, the cooling water spray mechanism is turned off, allowing the cooler air to directly enter the body for cooling. When the ambient temperature is too high, the cooling water spray mechanism of the gas precooling chamber is turned on, and the air entering the body is precooled through the heat exchange between the cooling water and the hot air, thereby reducing the temperature of the air entering the body and significantly improving the cooling effect of the hot water to be cooled.

[0028] With the second air inlet, when the gas temperature entering the gas precooling chamber is too high, it enters the partition heat exchanger through the first air inlet and exchanges heat with the spray water. The water temperature falling from the partition heat exchanger rises. At this time, the first fan opens to draw air from the gas precooling chamber, so that the gas entering from the second air inlet comes into direct contact with the water falling from the partition heat exchanger. The spray water undergoes a phase change, its temperature drops, and it falls into the water collection tank for subsequent cooling circulation. This process ensures that the water sprayed by the cooling water spraying mechanism onto the partition heat exchanger is always at a low temperature, thus continuously providing a high-efficiency cooling effect for the medium to be cooled.

[0029] 2. By setting multiple first spray heads, cooling water can be evenly sprayed from the water collection tank onto the surface of the heat exchange mechanism. This uniform spraying method significantly improves the uniformity of heat exchange between cooling water and hot air, thereby effectively improving the cooling efficiency of hot air.

[0030] 3. With the setting of the first sealing plate and the second sealing plate, the spray water enters from the spray water inlet and exits from the spray water outlet, and the air enters from the air inlet and exits from the air outlet. The spray water and the air do not come into direct contact, but heat exchange is achieved, so that the air entering the body is cold and dry air. When the cold and dry air comes into direct contact with the medium falling from the packing layer, it can absorb more heat from the medium through evaporation, thereby ensuring the cooling effect.

[0031] 4. With the second spray head, the hot water to be cooled can be sprayed evenly onto the packing layer, ensuring that the hot water and cold air are in full and even direct contact, thereby achieving efficient heat exchange and significantly improving the cooling effect.

[0032] 5. By setting up a first water collector and a second water collector, the first fan and the second fan will draw out the air in the gas precooling chamber and the main body. However, in the gas precooling chamber and the main body, the air and water are in direct contact and exchange heat, resulting in a large number of water droplets in the air. At this time, the first water collector and the second water collector can separate the water droplets from the air before the air is discharged from the gas precooling chamber and the main body, thereby reducing water loss, ensuring the long-term stable operation of the gas precooling chamber, and reducing the loss of the medium to be cooled.

[0033] 6. By setting up two gas precooling chambers, the gas flow rate entering the main body can be significantly increased and the gas temperature entering the main body can be reduced. After the cold air and hot water exchange heat, the cooling range of the hot water can be effectively improved, thereby ensuring the stability of the cooling effect. Attached Figure Description

Each second spray pipe 4 is arranged along the length direction of the tower body 1, and multiple second spray heads 11 are arranged along the length direction of each second spray pipe 4. In this specific embodiment, one end of the length direction of each second spray pipe 4 is located inside the tower body 1, and the other end of the length direction of each second spray pipe 4 extends outside the tower body 1. The section of the second spray pipe 4 located outside the tower body 1 is used to introduce the medium to be cooled. A second fan 10 is installed at the top of the tower body 1.

[0051] A gas precooling chamber 7 is provided on the outer wall surface of the main body corresponding to the air inlet 2. The opening corresponds to the position of the air inlet 2.

Multiple second spray heads 11 are arranged along the length of the second spray pipe 4. The hot water to be cooled can be evenly sprayed onto the packing layer 3 through the second spray heads 11, ensuring that the hot water and cold air are in full and uniform direct contact, thereby achieving efficient heat exchange and significantly improving the cooling effect.

[0056] like Figure 9-12 As shown, the partition heat exchange mechanism 9 includes multiple sets of heat exchange components. Each set of heat exchange components includes two heat exchange plates arranged in sequence, with a gap between adjacent heat exchange plates.

[0057] Each heat exchange assembly has a first sealing plate 22 at the top and bottom between the two heat exchange plates. The front and rear ends of the two heat exchange plates in each assembly are open, forming an air inlet and an air outlet. Figure 11-12 Air flows from point Q into the gap between the two heat exchange fins.

[0058] In two adjacent heat exchange components, the front and rear ends of the two heat exchange plates that are close to each other are equipped with second sealing plates 23. The top and bottom of the two heat exchange plates in the two adjacent heat exchange components are open, forming a spray water inlet and a spray water outlet. Figure 11 The spray water enters from point P into the gap between the two heat exchange plates and flows.

[0059] A water collection tank 12 is provided at the bottom of the gas precooling chamber 7; the cooling water spraying mechanism includes a water pump 13, a liquid pipe 14, and multiple first spray pipes 15. The inlet of the water pump 13 is connected to a water suction pipe 16, the other end of which is connected to the water collection tank 12. The outlet of the water pump 13 is connected to an outlet pipe 17, which is vertically arranged. The other end of the outlet pipe 17 extends into the gas precooling chamber 7 and is connected to the liquid pipe 14. The liquid pipe 14 is arranged along the width direction of the gas precooling chamber 7 and is connected to the liquid pipe 15. Both ends of the liquid pipe 14 are sealed. Each first spray pipe 15 is connected to the liquid pipe 14. Each first spray pipe 15 is arranged along the length of the gas precooling chamber 7.

Each first spray head 18 is located above the partition heat exchange mechanism 9. The structure of each first spray head 18 is the same as that of the second spray head 11.

[0060] A first water collector 20 is installed in the gas precooling chamber 7, and the first water collector 20 is located above the first spray pipe 15; a second water collector 21 is installed in the tower body 1 corresponding to the second spray pipe 4. The specific structure and installation method of the first water collector 20 and the second water collector 21 are existing technologies and will not be described in detail here. The first water collector 20 and the second water collector 21 can be selected from models that can separate moisture from the air, and will not be described in detail here.

[0061] The operation process of specific embodiment 1: When it is summer or the ambient air temperature is high, the cooling water spray mechanism is in the open state and the first fan at the top of the air precooling chamber is in the open state.

[0062] Gas at dry bulb temperature enters the gas precooling chamber through the first air inlet. The first spray head sprays cooling water onto the partition wall heat exchange mechanism. The hot gas at dry bulb temperature and the cooling water exchange heat. The gas at dry bulb temperature decreases in temperature and enters the main body through the air inlet. At this time, the hot water to be cooled is evenly sprayed onto the packing layer through the second spray head. The hot water to be cooled comes into direct contact with the cold air to exchange heat. After cooling, it eventually becomes cold water and falls to the lower part of the main body. At this time, it can be discharged through the outlet of the fluid to be cooled. The gas with increased temperature after heat exchange is drawn out of the main body by the second fan. Before being drawn out, the second water collector separates the moisture in the air.

[0063] The gas at dry bulb temperature will also enter the gas precooling chamber below the partition wall heat exchanger through the second air inlet. At this time, the air exchanges heat with the water that falls from the partition wall heat exchanger and the temperature rises. The spray water comes into direct contact with the air, and some of the water in the spray water will undergo a phase change, changing from liquid to gas, thereby achieving cooling. This will lower the temperature of the water that finally falls into the water collection tank. The gas after heat exchange is drawn out of the gas precooling chamber by the first fan. Before being drawn out, the first water collector will separate the moisture in the air.

[0064] When the ambient humidity around the body is low, the cooling water spray mechanism is closed, the first fan at the top of the cooling chamber is closed, and the outside air directly enters the body through the first channel to exchange heat with the medium.

[0065] In specific embodiment 2, such as Figure 4-12 As shown, the difference between this specific embodiment 2 and specific embodiment 1 is that: in this specific embodiment 2, there are two air inlets 2, and gas precooling chambers 7 are provided on both sides of the main body corresponding to the two air inlets 2.

[0066] The operation process of specific embodiment 2 is different from that of specific embodiment 1. In the operation process of specific embodiment 2, there are two gas precooling chambers for precooling the gas.

[0067] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components, and can be direct connections or indirect connections through an intermediate medium. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0068] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all implementation methods here, and any obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
