Description

Technical Field

[0001] This utility model relates to a closed cooling tower, specifically a composite flow cooling tower. Background Technology

[0002] The common working mode of a cooling tower is as follows: the medium that needs to be cooled is transported to the medium cooling mechanism, and the spray mechanism extracts the cool water with a lower temperature from the water collection tank at the bottom of the cooling tower and sprays it onto the medium cooling mechanism to lower the temperature of the medium to be cooled. The medium is cooled by water cooling. During this process, air is also introduced into the cooling tower to cool the medium by air cooling and to cool the heated cooling water. When the temperature of the air introduced into the cooling tower is low, the cooling effect of the medium can be guaranteed. However, when the temperature of the air introduced into the cooling tower is high or it is summer, the cooling effect cannot be guaranteed. Utility Model Content

[0003] In order to solve the problems in related technologies, this utility model provides a composite flow cooling tower. This device solves the problem that existing cooling towers cannot guarantee the cooling effect of the medium when the ambient air temperature is high.

[0004] To solve the above problems, the following technical solutions are provided:

[0005] A composite flow cooling tower includes a tower body, characterized in that the tower body has vertically arranged baffles, and a fan is located at the top of the tower body on one side of the baffles.

[0006] The tower body on the other side of the partition contains a medium cooling mechanism, a baffle and a partition-type heat exchange mechanism. The tower body above the medium cooling mechanism contains a spray mechanism. The baffle is horizontally arranged below the medium cooling mechanism. Three sides of the baffle are sealed to the three side walls of the tower body, and there is a gap between the other side of the baffle and the partition.

[0007] The partition wall heat exchange mechanism is inclinedly arranged below the baffle. The partition wall heat exchange mechanism divides the inner cavity of the tower below the baffle into two intersecting and connected spaces. There are air outlets on the partitions corresponding to the two spaces. One space is separated by the baffle and is not connected to the spray mechanism. The other space is connected to the spray mechanism through the gap between the baffle and the partition.

[0008] With the above technical solution, by setting up two staggered and non-connected spaces, the fan and spray mechanism are in the open state. The spray mechanism sprays cooling water onto the medium cooling mechanism. After water cooling, the medium is cooled and discharged from the medium cooling mechanism.

[0009] The spray mechanism sprays cooling water onto the medium cooling mechanism. After heat exchange, the cooled water falls and enters the partition heat exchange mechanism from the side without baffles. During the process of passing through the partition heat exchange mechanism, the air in the outside environment enters the partition heat exchange mechanism through the space that is not connected to the spray mechanism. During the process of passing through the partition heat exchange mechanism, it exchanges heat with the cooling water that enters the partition heat exchange mechanism. After the heat exchange, the cooled water falls, and the air after the heat exchange enters the tower cavity below the fan from the air outlet.

[0010] Due to the action of the fan, air from the outside environment will also enter the partition heat exchange mechanism through the space connected to the spray mechanism, and pass through the partition heat exchange mechanism under the action of the fan. During this process, it will come into direct contact with the cooling water sprayed on the medium cooling mechanism, which has been heated by heat exchange and then falls. At this time, the cooling water falling from the medium cooling mechanism undergoes a phase change and falls into the water collection tank from the spray water outlet, thereby ensuring the cooling effect of the cooling water.

[0011] Furthermore, a water distribution plate is provided within the gap between the baffle and the partition. The water distribution plate is connected in a sealed manner to the partition-type heat exchange mechanism, the two side walls of the tower body, and the partition on all four sides. The water distribution plate is an openable and closable water distribution plate.

[0012] With the above technical solution, by setting up an openable water distribution plate, when it is winter or the ambient air humidity is low, the cooling water sprayed by the spraying mechanism exchanges heat with the medium in the medium cooling mechanism. Although the cooling water is heated, there is no need to introduce additional air from the outside environment for cooling. At this time, when the water distribution plate is closed, the cooling water sprayed by the spraying mechanism will not fall on the partition wall heat exchange mechanism, but will fall directly into the bottom of the tower body, thereby saving energy while ensuring the cooling effect.

[0013] Furthermore, the air inlet corresponding to the space not connected to the spray mechanism has a first louver, the air outlet corresponding to the space not connected to the spray mechanism has a second louver, the top of the tower body corresponding to the spray mechanism has an air inlet, and the air inlet has a third louver.

[0014] Through the above technical solution, by setting the first louver, the second louver and the third louver, the amount of air entering the tower can be controlled by adjusting the angle of the blades. When operating at high temperature or high load, the air intake can be increased to improve cooling efficiency, and when operating at low temperature or low load, the air intake can be reduced to save energy, thereby optimizing the cooling effect of the tower.

[0015] Furthermore, a first water collector is located in the air outlet duct corresponding to the space connected to the spray mechanism. The first water collector is located in the tower cavity corresponding to the fan. There is a through hole on the partition plate corresponding to the lower part of the medium cooling mechanism. There is a second water collector in the tower cavity corresponding to the fan and the through hole.

[0016] Through the above technical solution, with the setting of the first and second water collectors, the air entering from the air inlet duct and coming into direct contact with the sprayed cooling water becomes hot and humid air. It will leave the tower body under the suction of the fan, but the air leaving through the through hole contains moisture. At this time, the second water collector will separate the moisture from the air leaving through the through hole. In the space connected to the spraying mechanism, air and cooling water coexist. The air leaving from the air outlet duct is hot and humid air, which will leave the tower body under the suction of the fan. However, the air leaving from the air outlet duct contains moisture. At this time, the first water collector will separate the moisture from the air leaving the air outlet duct. Both the first and second water collectors will separate the moisture from the air leaving the tower body, thereby reducing the loss of moisture in the tower body and thus reducing the maintenance cost of the tower body.

[0017] Furthermore, the partition heat exchange mechanism includes multiple sets of heat exchange components, each set of heat exchange components includes two heat exchange plates arranged sequentially and at an angle, and there is a gap between the two heat exchange plates in each set of heat exchange components. The multiple sets of heat exchange components are arranged in a sequential side-by-side, and there is a gap between the two heat exchange plates that are close to each other in two adjacent heat exchange components.

[0018] In each heat exchange assembly, there is a first sealing plate between the two heat exchange plates, between the side corresponding to the first louver and between the side corresponding to the second louver. The other two sides of the two heat exchange plates in each heat exchange assembly are open, forming an inclined air inlet and air outlet. The air inlet is connected to the first louver, and the air outlet is connected to the second louver.

[0019] In two adjacent heat exchange components, there are second sealing plates between the sides of the two heat exchange plates that are close to each other and the sides that are close to each other, corresponding to the air inlet below the first louver and the air outlet above the second louver. The other two sides of the two heat exchange plates that are close to each other in the two adjacent heat exchange components are open, forming an inclined spray water inlet and a spray water outlet. The spray water inlet is connected to the air outlet above the second louver, and the spray water outlet is connected to the air inlet below the first louver.

[0020] Through the above technical solution, the partitioned heat exchange mechanism between the air inlet and the air outlet forms a channel through the setting of the first sealing plate and the second sealing plate, which is used for the air entering from the first louver to flow. The partitioned heat exchange mechanism between the spray water inlet and the spray water outlet forms a channel for the air entering from the air inlet below the first louver and the cooling water falling from the medium cooling mechanism to flow. The two channels are different, so the heat exchange between the two channels is indirect, thereby avoiding the absorption of moisture from the air entering from the first louver and ensuring the dryness of the air. In addition, the air flowing between the spray water inlet and the spray water outlet is in direct contact with the cooling water, which can cause the cooling water to undergo a phase change, thereby ensuring the cooling effect of the cooling water.

[0021] Furthermore, the medium cooling mechanism includes a coil heat exchanger, with both the medium inlet end and the medium outlet end of the coil heat exchanger extending outside the tower body.

[0022] Furthermore, a water collection tank is provided inside the tower body below the partition wall heat exchange mechanism; the spraying mechanism includes a water pump, a pumping pipe, and a spraying pipe; one end of the pumping pipe is connected to the water collection tank, the other end of the pumping pipe is connected to the inlet of the water pump, one end of the spraying pipe is connected to the outlet of the water pump, and the other end of the spraying pipe extends into the tower body, with multiple spray heads connected to the bottom of the section of the spraying pipe located inside the tower body.

[0023] Through the above technical solution, the water in the water collection tank can be evenly sprayed onto the medium cooling mechanism by setting the spray head, thereby increasing the contact area between the medium and the cooling water, and more effectively exchanging heat with the air, thus improving the cooling efficiency.

[0024] Furthermore, two partitions are provided, and the partition-type heat exchange mechanism is located in each of the two spaced-apart cavities.

[0025] With the above technical solution, by setting up two partitions, cooling can be performed in the cavities on the sides of the partitions that are far apart from each other, thereby increasing cooling efficiency.

[0026] The above solution has the following advantages:

[0027] 1. By setting up two staggered and non-connected spaces, the fan and spray mechanism are in the open state. The spray mechanism sprays cooling water onto the medium cooling mechanism. After water cooling, the medium is cooled and discharged from the medium cooling mechanism.

[0028] The spray mechanism sprays cooling water onto the medium cooling mechanism. After heat exchange, the cooled water falls and enters the partition heat exchange mechanism from the side without baffles. During the process of passing through the partition heat exchange mechanism, the air in the outside environment enters the partition heat exchange mechanism through the space that is not connected to the spray mechanism. During the process of passing through the partition heat exchange mechanism, it exchanges heat with the cooling water that enters the partition heat exchange mechanism. After the heat exchange, the cooled water falls, and the air after the heat exchange enters the tower cavity below the fan from the air outlet.

[0029] Due to the action of the fan, the air in the outside environment will also enter the partition heat exchange mechanism through the space connected to the spray mechanism, and pass through the partition heat exchange mechanism under the action of the fan. During this process, it will come into direct contact with the cooling water sprayed on the medium cooling mechanism, which has been heated by heat exchange and then falls. At this time, the cooling water falling from the medium cooling mechanism undergoes a phase change and falls into the water collection tank from the spray water outlet, thereby ensuring the cooling effect of the cooling water.

[0030] 2. With the setting of the openable water distribution plate, when it is winter or the ambient air humidity is low, the cooling water sprayed by the spraying mechanism exchanges heat with the medium in the medium cooling mechanism. Although the cooling water is heated, there is no need to introduce additional air from the outside environment for cooling. At this time, the water distribution plate is closed, so the cooling water sprayed by the spraying mechanism will not fall on the partition wall heat exchange mechanism, but will fall directly into the bottom of the tower body, thereby saving energy while ensuring the cooling effect.

[0031] 3. By setting the first, second, and third louvers, the amount of air entering the tower can be controlled by adjusting the angle of the blades. When operating at high temperature or high load, the air intake can be increased to improve cooling efficiency, and when operating at low temperature or low load, the air intake can be reduced to save energy, thereby optimizing the cooling effect of the tower.

[0032] 4. With the installation of the first and second water collectors, the air entering from the air inlet duct and coming into direct contact with the sprayed cooling water becomes hot and humid air. It leaves the tower body under the suction of the fan, but the air leaving through the through hole contains moisture. At this time, the second water collector will separate the moisture from the air leaving through the through hole. In the space connected to the spraying mechanism, air and cooling water coexist. The air leaving from the air outlet duct is hot and humid air, which leaves the tower body under the suction of the fan. However, the air leaving from the air outlet duct contains moisture, and at this time, the first water collector will separate the moisture from the air leaving the air outlet duct. Both the first and second water collectors separate the moisture from the air leaving the tower body, thereby reducing the loss of moisture in the tower body and thus reducing the maintenance cost of the tower body.

[0033] 5. By setting up two partitions, cooling can be performed in the cavities on the sides of the partitions that are far apart from each other, thereby increasing cooling efficiency. Attached Figure Description

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] Specific Implementation Example 1: As shown in the example Figure 1-7 As shown, a composite flow cooling tower includes a tower body 1, and a vertically arranged partition 2 inside the tower body 1. In this specific embodiment 1, there is a partition 2 inside the tower body 1. The partition 2 is used to divide the interior of the tower body 1 into two cavities. A fan 3 is located at the top of the tower body 1 corresponding to one cavity of the partition 2.

[0048] The tower body 1 corresponding to the cavity on the other side of the partition 2 contains a medium cooling mechanism 4, a baffle 22 and a partition-type heat exchange mechanism 10. The tower body 1 above the medium cooling mechanism 4 contains a spray mechanism 6. The baffle 22 is horizontally arranged below the medium cooling mechanism 4. The three sides of the baffle 22 are sealed to the three side walls of the tower body 1, and there is a gap between the other side of the baffle 22 and the partition 2.

[0049] The partition heat exchange mechanism 10 is inclinedly arranged below the baffle 22. The partition heat exchange mechanism 10 divides the inner cavity of the tower body 1 below the baffle 22 into two intersecting and connected spaces. There are air outlets on the baffles 2 corresponding to the two spaces, and there are air inlets on the side wall of the tower body 1 that is away from the baffle 2 corresponding to the two spaces. One space is separated by the baffle 22 and is not connected to the spray mechanism 6. The other space is connected to the spray mechanism 6 through the gap between the baffle 22 and the baffle 2.

[0050] A water distribution plate 11 is located within the gap between the baffle 22 and the partition 2. The water distribution plate 11 is sealed to the partition heat exchange mechanism 10 on all four sides, and its sidewalls are sealed to the partition heat exchange mechanism 10, the two side walls of the tower body 1, and the partition 2. The water distribution plate 11 is an openable and closable water distribution plate. In this specific embodiment 1, the water distribution plate 11 includes two water distribution plates, a first water distribution plate and a second water distribution plate, arranged sequentially on top of each other. The first water distribution plate and the second water distribution plate have multiple through holes with corresponding positions. The first water distribution plate is sealed to the partition heat exchange mechanism 10, the two side walls of the tower body 1, and the partition 2 on all four sides. The first water distribution plate and the second water distribution plate have a rotating shaft at their center. The rotating shaft is rotatably connected to the center of the first water distribution plate and fixedly connected to the center of the second water distribution plate. When the first water distribution plate rotates until all the through holes on the second water distribution plate are blocked by the first water distribution plate, the water distribution plate 11 is in a closed state, and the spray water cannot pass through the water distribution plate 11 to enter the partition wall heat exchange mechanism 10. When the first water distribution plate rotates until the through holes on the first water distribution plate and the through holes on the second water distribution plate correspond, the water distribution plate 11 is in an open state, and the spray water can pass through the water distribution plate 11 to enter the partition wall heat exchange mechanism 10.

[0051] The first water distribution plate and the second water distribution plate are arranged in sequence from top to bottom, and the second water distribution plate can block or expose the through hole on the first water distribution plate by rotating. This technology is existing technology and will not be elaborated on here.

[0052] The air inlet 7 corresponding to the space not connected to the spray mechanism 6 is the first air inlet, and the air inlet 7 below the first air inlet is the second air inlet. The air inlet 7 corresponding to the space not connected to the spray mechanism 6 has a first louver 8, that is, the first air inlet has a first louver 8. The air outlet 9 corresponding to the space not connected to the spray mechanism 6 is the second opening, and the air outlet 9 corresponding to the space not connected to the spray mechanism 6 has a second louver 12, that is, the second opening has a second louver. The air outlet 9 above the second opening is the first opening. The top of the tower body 1 corresponding to the spray mechanism 6 has an air inlet 13, and the air inlet 13 has a third louver 21. The first louver 8, the first louver 22 and the third louver 21 are all movable louvers.

[0053] The air outlet duct 9 corresponding to the space connected to the spray mechanism 6 has a first water collector 14, which is located in the cavity of the tower body 1 corresponding to the fan 3; the partition plate 2 corresponding to the lower part of the medium cooling mechanism 4 has a through hole 5, and the cavity of the tower body 1 corresponding to the fan 3 and the through hole 5 has a second water collector 14.

[0054] like Figure 6-7As shown, the partition heat exchange mechanism 10 includes multiple sets of heat exchange components. Each set of heat exchange components includes two heat exchange plates arranged sequentially and at an angle. There is a gap between the two heat exchange plates in each set of heat exchange components. The multiple sets of heat exchange components are arranged in a sequential side-by-side. There is a gap between the two heat exchange plates that are close to each other in two adjacent heat exchange components.

[0055] In each heat exchange assembly, there is a first sealing plate 16 between the two heat exchange plates, between the side corresponding to the first louver 8 and between the side corresponding to the first louver 22. The other two sides of the two heat exchange plates in each heat exchange assembly are open, forming an inclined air inlet and air outlet. The air inlet is connected to the first louver 8, and the air outlet is connected to the second louver 12.

[0056] In two adjacent heat exchange components, there are second sealing plates 17 between the sides of the two heat exchange plates that are close to each other and the sides that are close to each other and the sides that are close to each other. The other two sides of the two heat exchange plates that are close to each other in the two adjacent heat exchange components are open, forming an inclined spray water inlet and spray water outlet. The spray water inlet is connected to the air outlet 9 above the second louver 12, and the spray water outlet is connected to the air inlet 7 below the first louver 8.

[0057] like Figure 2 As shown, the medium cooling mechanism 4 includes a coil heat exchanger. The lower part of the coil heat exchanger has a medium inlet end 18, and the upper part of the coil heat exchanger has a medium outlet end 19. Both the medium inlet end 18 and the medium outlet end 19 of the coil heat exchanger extend outside the tower body 1. The specific structure of the coil heat exchanger belongs to the prior art and will not be described in detail here.

[0058] like Figure 2 As shown, there is a water collection tank 20 inside the tower body 1 below the partition heat exchange mechanism 10.

[0059] like Figure 5 As shown, the spraying mechanism 6 includes a water pump 601, a water suction pipe 602, and a spray pipe 603. One end of the water suction pipe 602 is connected to the water collection tank 20, and the other end of the water suction pipe 602 is connected to the water inlet of the water pump 601. One end of the spray pipe 603 is connected to the water outlet of the water pump 601, and the other end of the spray pipe 603 extends into the tower body 1. The bottom of the section of the spray pipe 603 located inside the tower body is connected to multiple spray heads 23. The spray heads 23 can evenly spray the water in the water collection tank 20 onto the medium cooling mechanism 4, thereby increasing the contact area between the medium and the cooling water, and enabling more effective heat exchange with the air, thus improving the cooling efficiency.

[0060] In this specific embodiment 1, the spray pipe 603 includes a first liquid passage pipe 6031, a second liquid passage pipe 6032, and a plurality of third liquid passage pipes 6033. The outlet of the water pump 601 is connected to one end of the first liquid passage pipe 6031. The first liquid passage pipe 6031 is vertically arranged, and the other end of the first liquid passage pipe 6031 is connected to the peripheral wall of the second liquid passage pipe 6032. The second liquid passage pipe 6032 is arranged along the width direction of the tower body 1, and both ends of the second liquid passage pipe 6032 are sealed. The plurality of third liquid passage pipes 6033 are arranged sequentially along the width direction of the tower body 1. One end of each third liquid passage pipe 6033 is connected to the peripheral wall of the second liquid passage pipe 6032, and the other end of each third liquid passage pipe 6033 is sealed. The spray head is connected to the bottom of each third liquid passage pipe 6033.

[0061] The operation process of specific embodiment 1: When it is summer or the ambient air temperature is high, the first louver, the second louver and the third louver are opened, the water distribution plate and the fan are turned on, the medium enters the medium cooling mechanism from the medium inlet end, the spraying mechanism sprays the cooling water in the water collection tank onto the medium cooling mechanism, the air in the ambient environment enters the tower body through the air inlet hole, and after the cooling action of air cooling and water cooling, the medium is cooled and discharged from the medium outlet end. The air enters the tower body through the air inlet hole, and the heated air will be discharged from the through hole under the suction of the fan. However, because the air that enters the tower body through the air inlet hole and is sprayed by the cooling water of the spraying mechanism becomes hot and humid air after contact, the second water collector can separate the moisture in the air that is drawn away from the tower body by the fan.

[0062] After the cooling water sprayed by the spray mechanism heats up, it falls onto the water distribution plate. Since the water distribution plate is open at this time, the cooling water falling from the medium cooling mechanism will enter the spray water inlet. During the process of passing through the partition cooling mechanism, the air in the outside environment enters the air inlet through the first louver and exchanges heat with the cooling water entering the spray water inlet. The cooling water that has completed the heat exchange will fall from the spray water outlet and enter the partition heat exchange mechanism through the first louver. The air that has completed the heat exchange will enter the cavity below the fan from the air outlet.

[0063] Due to the action of the fan, the air in the outside environment will also enter the spray water discharge end through the air inlet below the first louver, and pass through the partition heat exchange mechanism under the suction of the fan. During this process, it will come into direct contact with the cooling water entering from the spray water inlet. At this time, the cooling water falling from the medium cooling mechanism will undergo a phase change and fall into the water collection tank from the spray water discharge end. Some of the liquid water falling from the medium cooling mechanism will turn into gaseous water, thereby ensuring the cooling effect of the cooling water.

[0064] The air entering the spray water outlet through the air inlet below the first louver and leaving the spray water outlet is hot and humid air. It will leave the tower body under the suction of the fan, but the air leaving from the open contains moisture. At this time, the first water collector will separate the moisture from the air leaving from the open.

[0065] When it is winter or the ambient air humidity is low, there is no need to introduce additional air from the outside environment to cool the cooling water. Therefore, the first, second, and third louvers are closed, the fan is turned off, and the water distribution plate is opened. The medium enters the medium cooling mechanism from the medium inlet end, and the spray mechanism sprays the cooling water in the water collection tank onto the medium cooling mechanism. After heat exchange, the medium is cooled and discharged from the medium outlet end. The medium is cooled by water cooling, and the cooled water sprayed on the medium cooling structure and heated falls into the water collection tank. In this environment, the fan and the third louver can also be opened, and the first and second louvers can be closed. Under the suction of the fan, the ambient air is drawn into the tower body, and the medium is cooled by air cooling. The air is then drawn out of the tower body through the through hole by the fan.

[0066] Specific embodiment 2, such as Figure 6-10 As shown, the difference between this specific embodiment 2 and specific embodiment 1 is that in this specific embodiment 2, there are two partitions 2, which divide the interior of the tower body 1 into three cavities. The tower body cavities on the opposite sides of the two partitions 2 are equipped with partition-type heat exchange mechanisms 10. When the partition-type heat exchange mechanisms 10 in each cavity are in working condition, the cooling efficiency can be accelerated.

[0067] The operation process of specific embodiment 2 is different from that of specific embodiment 1. In specific embodiment 2, it is possible to choose whether to open the partition heat exchange mechanism and the number of opening mechanisms as needed.

[0068] 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.

[0069] 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.
