Description

Technical Field

[0001] The utility model belongs to the technical field of water temperature balancing of cooling towers, and particularly relates to a water temperature balancing device for a cooling tower. Background Art

[0002] A cooling tower is a type of equipment that uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere, thereby lowering the water temperature. The working principle is to use the flow of water and air to exchange heat to generate steam, and to dissipate the waste heat generated in industry or refrigeration and air conditioning through evaporative heat dissipation, convection heat transfer and radiation heat transfer to lower the water temperature. It is an evaporative heat dissipation device mainly used in air conditioning cooling systems, refrigeration series and industrial water cooling fields.

[0003] In the cooling water system, the performance of the chiller, cooling water pump and cooling tower are interrelated and influence each other. Cooling water supply with lower temperature can improve the performance coefficient of the chiller, but cooling water supply with lower temperature also requires the cooling tower to have a larger cooling water volume and a larger air volume, which will make the cooling tower consume more electricity.

[0004] In order to ensure the cooling effect of the chiller, the cooling water inlet temperature needs to be optimized. The chiller evaporation temperature should be 3-4°C lower than the chilled water outlet temperature, and the chiller cooling water outlet temperature should be 2-4°C lower than the condenser temperature. This requires water temperature control of the cooling tower.

[0005] The cooling tower in the prior art mainly adopts manual control to regulate the water temperature. When the water temperature is high, the cooling tower fan is turned on to cool the cooling tower water temperature. When the water temperature is low, the steam valve is opened to heat the cooling tower water temperature. Although the manual control method can regulate the cooling tower water temperature, due to certain errors and delays in manual monitoring and control, the accuracy of the cooling tower water temperature control is poor, and the cost of cooling tower water temperature control is high.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a cooling tower water temperature balancing device.

[0007] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0008] The purpose of the utility model is to provide a cooling tower water temperature balancing device, which can regulate the water temperature of the cooling tower with high precision and low cost.

[0009] In order to achieve the above-mentioned purpose, a specific embodiment of the present invention provides a cooling tower water temperature balancing device, including: a tower body, a liquid storage tank, a water temperature control component, and a floating water temperature detection component.

[0010] A liquid storage tank is fixedly connected to the lower side of the tower body.

[0011] The water temperature control component is installed above the liquid storage tank. The water temperature control component includes a pair of cooling tower cooling fans. The pair of cooling tower cooling fans are fixedly installed above the tower body. A steam delivery pipe is arranged below the pair of cooling tower cooling fans. A plurality of groups of evenly distributed heat exchange guide pipes are fixedly connected below the steam delivery pipe. The steam delivery pipe and the plurality of groups of heat exchange guide pipes are all arranged in the liquid storage tank, and the steam delivery pipe is arranged through the liquid storage tank.

[0012] The floating water temperature detection component is assembled in the liquid storage tank. The floating water temperature detection component includes a fixed assembly part. The fixed assembly part is sleeved on the outside of the steam delivery pipe. A water temperature sensor is assembled below the fixed assembly part.

[0013] In one or more embodiments of the present invention, one end of the steam delivery pipe located outside the liquid storage tank is fixedly connected to a delivery connecting pipe, which delivers temperature-controlling steam to a cooling fan in the cooling tower through the delivery connecting pipe.

[0014] In one or more embodiments of the present invention, multiple sets of heat exchange guide tubes are threadedly connected to drain pipes at their ends distal from the steam delivery pipes. These drain pipes have drainage holes at their lower ends. This facilitates the drainage of liquefied liquid from the heat exchange guide tubes through the drain pipes and the drainage holes, ensuring the heat exchange guide tubes effectively guide and deliver steam for temperature control.

[0015] In one or more embodiments of the present invention, a support filter is fixedly connected to the drain hole. The support filter supports and limits the limit block and return spring, thereby facilitating movement of the connecting guide rod. A connecting guide rod is slidably mounted within the support filter, and the support filter is mounted on the outside of the connecting guide rod. The connecting guide rod connects and secures the blocking block and the limit block.

[0016] In one or more embodiments of the present invention, a blocking block is fixedly connected to one end of the connecting guide rod located outside the drain pipe. The blocking block is configured to cooperate with the drain hole. The blocking block blocks the drain hole, thereby facilitating control of the drain pipe's conduction and drainage status by controlling the movement of the blocking block. A limiting block is fixedly connected to one end of the connecting guide rod located inside the drain pipe. The limiting block acts as a sliding limiter for the connecting guide rod.

[0017] In one or more embodiments of the present invention, a return spring is sleeved on the outer side of the connecting guide rod, and the return spring is arranged between the limit block and the supporting filter screen. The limit block is supported and limited by the contraction and reset of the return spring.

[0018] In one or more embodiments of the present invention, a tie rope is fixedly connected to the side of the fixed assembly proximal to the water temperature sensor. This tie rope provides a position-limiting connection between the fixed assembly and the floating plate. The end of the tie rope, distal to the fixed assembly, is fixedly connected to the floating plate. The floating plate supports and limits the retractable rod. Furthermore, the floating plate's floating position on the liquid surface of the liquid storage tank ensures the stability of the water temperature sensor's temperature detection of the water flow within the liquid storage tank.

[0019] In one or more embodiments of the present invention, a retractable rod is fixedly connected below the floating plate. The retractable rod serves as a stowage limiter for the extension rod. The extension rod is internally threadedly connected to the retractable rod. The temperature detection depth of the water temperature sensor is adaptively adjusted by controlling the extension rod's extension.

[0020] In one or more embodiments of the present invention, one end of the extension rod outside the retracting rod is fixedly connected to a fixing seat, and the fixing seat is sleeved on the outside of the water temperature sensor. The fixing seat plays a role in assembling and fixing the water temperature sensor.

[0021] Compared with the prior art, the cooling tower water temperature balancing device disclosed in the present invention can perform real-time water temperature detection and water temperature regulation on the cooling water tower through corresponding structural settings, thereby improving the accuracy of water temperature regulation on the cooling water tower and reducing the energy consumption of water temperature regulation on the cooling water tower.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 5 As shown, a cooling tower water temperature balancing device in one embodiment of the present invention includes: a tower body 1, a liquid storage tank 101, a water temperature control component 2, and a floating water temperature detection component 3.

[0032] like Figures 1 to 5 As shown, a liquid storage tank 101 is fixedly connected to the bottom of the tower body 1. The liquid storage tank 101 plays a role in storing liquid for the tower body 1.

[0033] like Figures 1 to 2 As shown, the water temperature control assembly 2 is mounted above the liquid storage tank 101 and includes a pair of cooling tower heat dissipation fans 201 fixedly mounted above the tower body 1. By controlling the operation of the pair of cooling tower heat dissipation fans 201, air circulation within the tower body 1 is accelerated, thereby dissipating heat and cooling the water stored in the liquid storage tank 101.

[0034] Specifically, the brand of the cooling tower heat dissipation fan 201 is EBMPAPST, and the model of the cooling tower heat dissipation fan 201 is S3G500-AM56-21.

[0035] like Figures 1 to 4 As shown, a steam delivery pipe 202 is arranged below a pair of cooling tower heat dissipation fans 201. Steam for temperature control is delivered to the liquid storage tank 101 through the steam delivery pipe 202, thereby facilitating the temperature increase of the water stored in the liquid storage tank 101.

[0036] like Figures 1 to 4 As shown, one end of the steam delivery pipe 202 outside the liquid storage tank 101 is fixedly connected to a delivery connecting pipe 204. The delivery connecting pipe 204 delivers temperature control steam to the cooling tower heat dissipation fan 201.

[0037] It is worth noting that the end of the delivery connecting pipe 204 away from the steam delivery pipe 202 is connected to a solenoid valve, which controls the conduction state of the delivery connecting pipe 204. The end of the solenoid valve away from the delivery connecting pipe 204 is externally connected to a steam delivery pipeline.

[0038] like Figures 1 to 4 As shown, multiple sets of evenly distributed heat exchange guide tubes 203 are fixedly connected below the steam delivery tube 202. The steam delivery tube 202 and the multiple sets of heat exchange guide tubes 203 are all arranged in the liquid storage tank 101, and the steam delivery tube 202 is set to penetrate the liquid storage tank 101. The steam delivered in the steam delivery tube 202 is guided by the multiple sets of heat exchange guide tubes 203, and the water stored in the liquid storage tank 101 is heated by heat exchange between the heat exchange guide tubes 203 and the water in the liquid storage tank 101.

[0039] like Figures 1 to 2 As shown, the ends of the multiple heat exchange guide tubes 203 away from the steam delivery tube 202 are all threadedly connected to drain pipes 205, and the lower ends of the drain pipes 205 are provided with drainage holes. This facilitates the drainage of the liquid liquefied after heat exchange within the heat exchange guide tubes 203 through the drain pipes 205 and the drainage holes, ensuring that the heat exchange guide tubes 203 effectively guide and transport the steam used for temperature control.

[0040] like Figures 1 to 2 As shown, the drain hole is fixedly connected with a supporting filter 206. The supporting filter 206 plays a supporting and limiting role for the limit block 209 and the return spring 210, thereby facilitating the movement and limiting of the connecting guide rod 207.

[0041] like Figures 1 to 2 As shown, a connecting guide rod 207 is slidably mounted in the supporting filter screen 206, and the supporting filter screen 206 is sleeved on the outside of the connecting guide rod 207. The connecting guide rod 207 plays a role in connecting and fixing the blocking block 208 and the limiting block 209.

[0042] like Figures 1 to 2As shown, a blocking block 208 is fixedly connected to one end of the connecting guide rod 207 outside the drain pipe 205. The blocking block 208 is arranged in conjunction with the drain hole. The blocking block 208 blocks the drain hole and limits the position, thereby facilitating the control of the conduction and drainage state of the drain pipe 205 by controlling the movement of the blocking block 208.

[0043] like Figures 1 to 2 As shown, one end of the connecting guide rod 207 located in the discharge pipe 205 is fixedly connected to a limiting block 209. The limiting block 209 plays a role of sliding limit for the connecting guide rod 207.

[0044] like Figures 1 to 2 As shown, the outer side of the connecting guide rod 207 is provided with a return spring 210, and the return spring 210 is arranged between the limit block 209 and the supporting filter 206. The limit block 209 is supported and limited by the contraction and reset of the return spring 210.

[0045] like Figures 1 to 4 As shown, the floating water temperature detection assembly 3 is assembled in the liquid storage tank 101 and includes a fixed assembly 301, which is sleeved on the outside of the steam delivery pipe 202. The fixed assembly 301 plays a role in fixing and limiting the involvement rope 303.

[0046] like Figures 1 to 4 As shown, a water temperature sensor 302 is installed below the fixed assembly 301. The water temperature sensor 302 monitors the water temperature stored in the liquid storage tank 101 in real time.

[0047] Specifically, the brand of the water temperature sensor 302 is TZW, and the model is 10K.

[0048] It is worth noting that in actual application, the water temperature sensor 302, the cooling tower cooling fan 201 and the solenoid valve are all electrically connected to the PLC control module. The PLC control module can control the operating status of the cooling tower cooling fan 201 and the solenoid valve according to the detection data of the water temperature sensor 302. By controlling the operating status of the cooling tower cooling fan 201, the water in the liquid storage tank 101 is dissipated and cooled. By controlling the conduction state of the solenoid valve, the steam delivery state of the steam delivery pipe 202 is controlled, thereby heating the water stored in the liquid storage tank 101.

[0049] like Figures 3 and 4 As shown, a connecting rope 303 is fixedly connected to one side of the fixed assembly part 301 close to the water temperature sensor 302. The connecting rope 303 is used to connect and limit the fixed assembly part 301 and the floating plate 304.

[0050] like Figures 3 and 4As shown, the end of the tie rope 303 away from the fixed assembly 301 is fixedly connected to a floating plate 304. Floating plate 304 supports and limits the retractable rod 305. Furthermore, by allowing floating plate 304 to float on the surface of the liquid in the liquid storage tank 101, the stability of the water temperature sensor 302 in detecting the temperature of the water in the liquid storage tank 101 is ensured.

[0051] like Figures 3 and 4 As shown, a retracting rod 305 is fixedly connected to the bottom of the floating plate 304. The retracting rod 305 plays the role of accommodating and limiting the extension rod 306.

[0052] like Figures 3 and 4 As shown, the contraction rod 305 is internally threadedly connected to the extension rod 306. By controlling the extension of the extension rod 306, the temperature detection depth of the water temperature sensor 302 is adaptively adjusted.

[0053] like Figures 3 and 4 As shown, one end of the extension rod 306 outside the contraction rod 305 is fixedly connected to a fixing seat 307, and the fixing seat 307 is sleeved on the outside of the water temperature sensor 302. The fixing seat 307 plays the role of assembling and fixing the water temperature sensor 302.

[0054] During specific use, the temperature of the water stored in the liquid storage tank 101 is monitored through the water temperature sensor 302. When the water temperature in the liquid storage tank 101 is high, the air circulation in the tower body 1 can be accelerated by controlling the operation of a pair of cooling tower cooling fans 201, thereby dissipating heat and cooling the water stored in the liquid storage tank 101.

[0055] When the water temperature in the liquid storage tank 101 is high, steam can be transported to the steam delivery pipe 202 by connecting the steam to the delivery connecting pipe 204. The steam is distributed to the multiple groups of heat exchange guide pipes 203 under the action of the steam delivery pipe 202. The water stored in the liquid storage tank 101 is heated by heat exchange between the multiple groups of heat exchange guide pipes 203 and the water in the liquid storage tank 101.

[0056] In addition, when steam liquefaction occurs in multiple sets of heat exchange guide tubes 203 during the heat exchange process, the liquefied water can accumulate in the drain pipe 205. When the gravity of the water accumulated in the drain pipe 205 is greater than the elastic force of the return spring 210, the blocking block 208 can move under the action of the gravity of the water, thereby making the drainage hole at the bottom of the drain pipe 205 conductive, and draining out the water accumulated in the drain pipe 205, thereby ensuring the stability of the heat exchange guide tube 203 in guiding steam.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
