Description

Technical Field

[0001] This application relates to the field of cooling equipment technology, and in particular to a dry-wet combined spliced ​​closed cooling tower. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant. Its main function is to absorb heat from a system (heat source) and release it into the atmosphere, thereby lowering the water temperature. Its working principle is based on the flow and contact between water and air, dissipating waste heat generated in industrial or refrigeration and air conditioning systems through evaporative heat dissipation, convective heat transfer, and radiative heat transfer, ensuring the normal operation of the system.

[0003] Traditional open cooling towers mainly rely on hot circulating water from a heat source being sprayed onto the packing material. The flowing air then exchanges heat with the hot circulating water adhering to the packing material to achieve a cooling effect. The cooled circulating water drips into a water pool at the bottom of the cooling tower and re-enters the heat source's circulation system. However, during this process, the circulating water is easily contaminated by external impurities. These impurities can easily accumulate in the pipes that transport the circulating water, and in severe cases, may cause blockages in the pipes, thus presenting a drawback. Utility Model Content

[0004] In order to improve the problems of traditional cooling towers, this application provides a dry-wet combined spliced ​​closed cooling tower.

[0005] The dry-wet combined spliced ​​closed cooling tower provided in this application adopts the following technical solution: A combined wet and dry closed-loop cooling tower includes a housing, the housing being hollow inside and open on both sides. A fan electrically connected to a control system is installed on the top of the housing. A hollow side chamber with an open top is detachably installed at the open end of the housing. A portal frame is installed on the top of the side chamber. A circulating water pipe is installed on the portal frame. A spray pipe is slidably installed on the portal frame. Several nozzles are connected to the spray pipe, and the nozzles face the circulating water pipe. A sliding component is installed on the portal frame to drive the spray pipe to slide back and forth. A water supply component is installed on the side chamber for supplying water to the spray pipe.

[0006] By adopting the above technical solution, the hot circulating water from the heat source circulates along the circulating water pipe. The control system starts the fan, which creates negative pressure inside the housing. Outside air flows into the housing through the portal frame. At the same time, the sliding component drives the spray pipe to slide, and the water supply component supplies water to the spray pipe. This causes the nozzles on the spray pipe to spray cooling water onto the circulating water pipe. The cooling water on the circulating water pipe absorbs heat from the hot circulating water from the heat source through heat transfer, while the airflow quickly carries away the hot air from the circulating water pipe. In this way, the hot circulating water inside the circulating water pipe is cooled. During this process, the possibility of the hot circulating water from the heat source being contaminated by direct contact with the outside is avoided.

[0007] Optionally, the sliding component includes a slide rail disposed on the portal frame, a slider slidably disposed on the slide rail, a spray pipe disposed on the slider, and two rotatable pulleys disposed on the portal frame at both ends along the length of the slide rail. A rope is wound around both pulleys, and the slider is fixed to the rope. A forward and reverse motor electrically connected to the control system is disposed on the portal frame, and one of the pulleys is coaxially disposed on the output shaft of the forward and reverse motor. Contact switches electrically connected to the control system are disposed at both ends of the slide rail, and the trigger end of the contact switch points to the slider.

[0008] By adopting the above technical solution, the control system starts the forward and reverse motor. The output shaft of the forward and reverse motor drives one of the reels to rotate in the forward direction. The rotating reel causes the rope to drive the slider to slide along the length of the slide rail through friction until the slider triggers the contact switch. At this time, the control system controls the output shaft of the forward and reverse motor to rotate in the reverse direction. This process is repeated so that the nozzle continuously cools the circulating water pipe.

[0009] Optionally, the water supply component includes a water pump mounted on the side box and electrically connected to the control system, with a flexible hose connecting the water pump's outlet end to the spray pipe.

[0010] By adopting the above technical solution, the control system starts the water pump, which delivers cooling water to the spray pipe during the movement through a hose, thereby achieving the effect of continuously cooling the circulating water pipeline.

[0011] Optionally, the circulating water pipes are arranged in a continuous S-shape on the portal frame, and the circulating water pipes are provided with a number of fins.

[0012] By adopting the above technical solution, the surface area of ​​the circulating water pipe is increased. On the one hand, this improves the heat exchange efficiency with the air, and on the other hand, it increases the contact area with the cooling water, which is conducive to the rapid dissipation of heat from the circulating water pipe.

[0013] Optionally, a filter screen is provided at the open end of the housing.

[0014] By adopting the above technical solution, during the airflow through the filter screen, the moisture in the airflow will condense on the filter screen and flow into the interior of the housing, thereby reducing the consumption of cooling water.

[0015] Optionally, a backflow plate is provided inside the housing, and the backflow plate corresponds one-to-one with the filter screen. The backflow plate is inclined towards the side box in a downward direction, and the bottom of the inclined backflow plate is located at the top opening of the side box. The filter screen is inclined away from the side box in a downward direction.

[0016] By adopting the above technical solution, the cooling water flowing downward along the filter screen will flow onto the anti-flow plate and then flow downward along the inclined anti-flow plate into the side box, thereby realizing the recycling and reuse of cooling water and reducing the consumption of cooling water.

[0017] Optionally, the side box is equipped with a cooler that is electrically connected to the control system.

[0018] By adopting the above technical solution, the control system starts the cooler, which cools the cooling water in the side box, thereby solving the problem that the cooling effect of the cooling water on the circulating water pipes becomes worse due to the increased temperature of the cooling water in the side box.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. The hot circulating water from the heat source circulates along the circulating water pipe. The control system starts the fan, which creates negative pressure inside the box. Outside air flows into the box through the portal frame. At the same time, the sliding component drives the spray pipe to slide, and the water supply component supplies water to the spray pipe. This causes the nozzles on the spray pipe to spray cooling water onto the circulating water pipe. The cooling water on the circulating water pipe absorbs heat from the hot circulating water from the heat source through heat transfer, while the airflow quickly carries away the hot air from the circulating water pipe. This achieves the cooling process of the hot circulating water in the circulating water pipe. In this process, the possibility of the hot circulating water from the heat source being contaminated by direct contact with the outside is avoided. 2. The control system starts the forward and reverse motor. The output shaft of the forward and reverse motor drives one of the reels to rotate in the forward direction. The rotating reel causes the rope to move the slider along the length of the slide rail through friction until the slider triggers the contact switch. At this time, the control system controls the output shaft of the forward and reverse motor to rotate in the reverse direction. This process is repeated so that the nozzle continuously cools the circulating water pipe. 3. The cooling water flowing down the filter screen will flow onto the anti-flow plate and then flow down the inclined anti-flow plate into the side box, thereby realizing the recycling and reuse of cooling water and reducing the consumption of cooling water.

[0024] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0025] This application discloses a dry-wet combined splicing closed cooling tower.

[0026] Reference Figure 1 and Figure 2 A dry-wet combined spliced ​​closed cooling tower includes a box body 1, the box body 1 is hollow inside and open on both sides in the horizontal direction, an exhaust pipe 14 is welded to the top of the box body 1, a fan 2 electrically connected to the control system is bolted to the exhaust pipe 14, a side box 3 that is hollow inside and open at the top is bolted to the open end of the box body 1, and a cooler 13 electrically connected to the control system is bolted to the side box 3.

[0027] Reference Figure 2 A filter screen 11 is bolted to the open end of the housing 1. The filter screen 11 is inclined towards the side housing 3 from top to bottom. A counterflow plate 12 is bolted inside the housing 1. The counterflow plate 12 corresponds to the filter screen 11. The counterflow plate 12 is inclined towards the side housing 3 from top to bottom. The lowest point of the counterflow plate 12 is located at the top opening of the side housing 3. The lowest point of the filter screen 11 is located on the inclined surface of the counterflow plate 12.

[0028] Reference Figure 1 and Figure 2 A portal frame 4 is welded to the top of the side box 3. A circulating water pipe 5 is bolted inside the portal frame 4. The circulating water pipe 5 is arranged in a continuous S-shape inside the portal frame 4. Several fins 10 are welded on the circulating water pipe 5.

[0029] When the outside air temperature is low, the control system starts the fan 2, which creates negative pressure inside the housing 1. Outside air flows into the housing 1 through the portal frame 4. During this process, the airflow carries away the heat from the circulating water pipe 5, thereby cooling the hot circulating water inside the circulating water pipe 5 and achieving the air cooling effect of the circulating water pipe 5.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A spray pipe 6 is slidably arranged on the portal frame 4. Several nozzles 7 are connected to the spray pipe 6. The nozzles 7 face the circulating water pipe 5. A sliding component 8 is arranged on the portal frame 4 to drive the spray pipe 6 to slide back and forth.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The sliding component 8 includes a slide rail 81 bolted to the portal frame 4, a slider 82 slidably arranged on the slide rail 81, a spray pipe 6 bolted to the slider 82, and two pulleys 83 rotatably connected to both ends of the portal frame 4 along the length of the slide rail 81, with a rope 84 wound around both pulleys 83.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The slider 82 is fixed on the rope 84. A forward and reverse motor 85, which is electrically connected to the control system, is bolted to the gantry frame 4. One of the pulleys 83 is coaxially bolted to the output shaft of the forward and reverse motor 85. Both ends of the slide rail 81 are bolted with contact switches 86, which are electrically connected to the control system. The trigger end of the contact switch 86 points to the slider 82.

[0033] Reference Figure 1 and Figure 2 The side box 3 is provided with a water supply component 9 for supplying water to the spray pipe 6. The water supply component 9 includes a water pump 91 that is bolted to the side box 3 and electrically connected to the control system. A hose 92 of sufficient length is connected between the outlet end of the water pump 91 and the spray pipe 6.

[0034] When the outside air temperature is high, the control system starts the cooler 13, which continuously cools the cooling water in the side box 3. At the same time, the control system starts the water pump 91 and the forward and reverse motor 85. The water pump 91 injects a large amount of cooling water into the spray pipe 6 through the hose 92, and the cooling water is sprayed from the nozzle 7 to the circulating water pipe 5.

[0035] At the same time, the output shaft of the forward and reverse motor 85 drives one of the pulleys 83 to rotate in the forward direction. The rotating pulley 83 causes the rope 84 to drive the slider 82 to slide along the length of the slide rail 81 through friction until the slider 82 triggers the contact switch 86. At this time, the control system controls the output shaft of the forward and reverse motor 85 to rotate in the reverse direction, and repeats this process, so that cooling water continuously flows on the surface of the circulating water pipe 5 and the fins 10.

[0036] In this way, the hot circulating water in the circulating water pipe 5 is continuously cooled down, and the water mist formed by the sprayed cooling water condenses on the filter screen 11 during the process of flowing through the filter screen 11, and flows along the inclined counterflow plate 12 into the side box 3.

[0037] The implementation principle of a dry-wet combined spliced ​​closed cooling tower in this application embodiment is as follows: When the outside air temperature is low, the control system starts the fan 2, and the fan 2 creates negative pressure inside the box 1. Outside air flows into the inside of the box 1 through the portal frame 4. During this process, the flowing air carries away the heat on the circulating water pipe 5, thereby cooling the hot circulating water inside the circulating water pipe 5, thus achieving the air cooling effect on the circulating water pipe 5.

[0038] When the outside air temperature is high, the control system starts the cooler 13, which continuously cools the cooling water in the side box 3. At the same time, the control system starts the water pump 91 and the forward and reverse motor 85. The water pump 91 injects a large amount of cooling water into the spray pipe 6 through the hose 92, and the cooling water is sprayed from the nozzle 7 to the circulating water pipe 5.

[0039] At the same time, the output shaft of the forward and reverse motor 85 drives one of the pulleys 83 to rotate in the forward direction. The rotating pulley 83 causes the rope 84 to drive the slider 82 to slide along the length of the slide rail 81 through friction until the slider 82 triggers the contact switch 86. At this time, the control system controls the output shaft of the forward and reverse motor 85 to rotate in the reverse direction, and repeats this process, so that cooling water continuously flows on the surface of the circulating water pipe 5 and the fins 10.

[0040] In this way, the hot circulating water in the circulating water pipe 5 is continuously cooled down, and the water mist formed by the sprayed cooling water condenses on the filter screen 11 during the process of flowing through the filter screen 11, and flows along the inclined counterflow plate 12 into the side box 3.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
