Description

Technical Field

[0001] This utility model relates to the field of condensate recovery and treatment technology, and more specifically, to a sample water cooler for power plants. Background Technology

[0002] As a primary source of heating, steam, and industrial steam for cities, the safe operation of thermal power plants is of paramount importance. With rapid technological advancements, the safety and environmental friendliness of thermal power plants have gradually improved, making the safe operation of condensate recovery and treatment systems particularly crucial. During operation of the cation exchange and mixed bed systems in the condensate workshop, the water temperature reaches approximately 50℃, exceeding the normal operating temperature (30℃) required by online instruments. This affects the accuracy of normal water quality monitoring, making it impossible to adjust the operating conditions of the cation exchange and mixed bed systems. In severe cases, abnormal situations such as water quality exceeding standards may occur.

[0003] To maintain the condensate at the normal operating temperature of online instruments, existing technologies utilize a self-made sample water cooler made of stainless steel pipes, with inlet and outlet cooling water pipes installed to cool the sample water in the cation exchange bed and mixed bed. This keeps the sample water temperature around 30℃, ensuring the accuracy of monitoring data. However, the temperature of the cooling water inside the cooler gradually rises after prolonged use. In hot weather, the temperature difference between the cooling water and the sample water becomes small, significantly reducing the cooling efficiency of the sample water. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a sample water cooler for power plants.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample water cooler for a power plant, comprising a base plate and a sample water pipe. Support rods are fixedly connected to both sides of the top of the base plate, and a sample water cooler body is fixedly connected to the top of each support rod. The sample water pipe is fixedly connected to the inner side of the sample water cooler body and extends from the side of the sample water cooler body. A first support assembly is fixedly connected to the left side of the top of the base plate, and a heat dissipation assembly is installed on the top of the first support assembly. A second support frame is fixedly connected to the right side of the top of the base plate. A circulating water pump, a cooling assembly, and a filter assembly are sequentially installed on the top of the second support frame from left to right. The sample water cooler body, heat dissipation assembly, circulating water pump, cooling assembly, and filter assembly are sequentially connected via water pipes, and the filter assembly is connected to the sample water cooler body via water pipes.

[0006] As a preferred embodiment of the present invention, the heat dissipation assembly includes a mounting plate fixedly connected to the top of the first bracket assembly, a first heat sink fixedly connected to the top of the mounting plate, a second heat sink fixedly connected to the inner side of the first heat sink, a pipe connector fixedly connected to the side of the first heat sink, and a cooling water hole opened in the middle of the side of the first heat sink.

[0007] As a preferred embodiment of the present invention, the first support assembly includes a first support frame, a fan compartment is provided on the top of the first support frame, and a cooling fan is installed on the inner side of the fan compartment.

[0008] As a preferred technical solution of this utility model, the first bracket frame has an installation groove on the front side, and the fan hopper has positioning grooves on both sides of the inner wall. The fan hopper has a first magnetic block fixedly connected to the back side of the inner wall. The first bracket assembly (2) has a dustproof assembly (3) installed on the inner side. The dustproof assembly includes a dustproof net. The dustproof net has a handle block fixedly connected to the front side and a second magnetic block fixedly connected to the back side of the dustproof net.

[0009] As a preferred embodiment of the present invention, the refrigeration assembly includes a refrigeration box fixedly connected to the top of the second support frame, a semiconductor refrigeration chip is installed on the top of the refrigeration box, and a temperature sensor is installed on the left side of the refrigeration box.

[0010] As a preferred embodiment of this utility model, a filter element is detachably installed on the top of the inner wall of the filter assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model incorporates a heat dissipation component and a heat dissipation fan. When the circulating water pump is activated, the cooling water flows through the right side of the sample water cooler body, passing sequentially through the filter component, the refrigeration component, and the circulating water pump before entering the cooling water holes of the first heat sink. The first heat sink has a large contact area with the air and excellent thermal conductivity, thus transferring the heat of the cooling water to the nearby air. Activating the heat dissipation fan accelerates the airflow, causing the air to flow upwards, which blows away the hot air near the heat dissipation component, achieving air cooling and cooling of the cooling water. The cooled water then returns to the interior of the sample water cooler body from the left side, thereby increasing the temperature difference between the cooling water and the sample water and improving the cooling efficiency of the sample water.

[0013] 2. This utility model incorporates a cooling component. When the ambient temperature is too high and the heat dissipation component cannot meet the cooling demand of the cooling water, a semiconductor cooling chip is activated. The cooling surface at the bottom of the semiconductor cooling chip cools the cooling water inside the cooling chamber, while the top of the semiconductor cooling chip serves as a heat dissipation surface, thus achieving rapid cooling of the cooling water. A circulating water pump then pumps the cooled water into the main body of the sample water cooler, significantly improving the cooling efficiency of the cooling water. Furthermore, a temperature sensor monitors the water temperature inside the cooling chamber. When the water temperature falls below a set range, the semiconductor cooling chip stops operating.

[0021] 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.

[0022] like Figures 1 to 6 As shown, this utility model provides a sample water cooler for a power plant, including a base plate 1 and a sample water pipe 103. Support rods 101 are fixedly connected to both sides of the top of the base plate 1, and a sample water cooler body 102 is fixedly connected to the top of each support rod 101. The sample water pipe 103 is fixedly connected to the inner side of the sample water cooler body 102 and extends from the side of the sample water cooler body 102. A first support assembly 2 is fixedly connected to the left side of the top of the base plate 1. A dustproof assembly 3 is installed inside the first support assembly 2, and a heat dissipation assembly 4 is installed on the top of the first support assembly 2. A second support frame 5 is fixedly connected to the right side of the top of the base plate 1. A circulating water pump 6, a cooling assembly 7, and a filter assembly 8 are sequentially installed from left to right on the top of the second support frame 5. The sample water cooler body 102, heat dissipation assembly 4, circulating water pump 6, cooling assembly 7, and filter assembly 8 are sequentially connected by water pipes. The filter assembly 8 is connected to the sample water cooler body 102 by a water pipe.

[0023] In this embodiment, cooling water is provided inside the sample water cooler body 102. The sample water cooler body 102, heat dissipation component 4, circulating water pump 6, refrigeration component 7 and filter component 8 are connected by water pipes to form a loop. The sample water is located inside the sample water pipe 103 and flows through the sample water cooler body 102. The sample water inside the sample water pipe 103 and the cooling water inside the sample water cooler body 102 are cooled through heat exchange, so that the temperature of the sample water is maintained at about 30°C, thereby meeting the detection requirements.

[0024] When the cooling water inside the sample water cooler body 102 is used for a long time, its temperature will gradually increase, and then the temperature difference between the cooling water and the sample water will decrease, which will reduce the heat exchange efficiency and thus reduce the cooling efficiency of the sample water.

[0025] The circulating water pump 6 is started to drive the cooling water to flow. The cooling water passes through the filter assembly 8, the refrigeration assembly 7 and the circulating water pump 6 in sequence on the right side of the sample water cooler body 102 and enters the cooling water hole of the first heat sink 402. The first heat sink 402 has a large contact area with the air and has good thermal conductivity, so it can transfer the heat of the cooling water to the nearby air.

[0026] The heat dissipation component 4 includes a mounting plate 401 fixedly connected to the top of the first bracket component 2. A first heat sink 402 is fixedly connected to the top of the mounting plate 401. A second heat sink 403 is fixedly connected to the inner side of the first heat sink 402. A pipe connector 404 is fixedly connected to the side of the first heat sink 402. A cooling water hole is opened in the middle of the side of the first heat sink 402.

[0027] The pipe connector 404 is connected to the cooling water hole. The first heat sink 402 and the second heat sink 403 are both made of aluminum alloy, which has excellent thermal conductivity. The second heat sink 403 can increase the structural strength between the first heat sink 402 and the first heat sink 402.

[0028] The first support assembly 2 includes a first support frame 201 fixedly installed on the top of the base plate 1. A fan compartment 211 is provided on the top of the first support frame 201, and a cooling fan 202 is installed on the inner side of the fan compartment 211.

[0029] The cooling fan 202 is activated to accelerate airflow and drive the air upward, which can blow away the hot air near the heat dissipation component 4, thereby achieving air cooling of the cooling water. The cooled water returns to the interior of the sample water cooler body 102 from the left side, thereby increasing the temperature difference between the cooling water and the sample water and improving the cooling efficiency of the sample water.

[0030] The first support frame 201 has an installation groove 204 on its front side, and positioning grooves 203 are provided on both sides of the inner wall of the fan hopper 211. A first magnetic block 205 is fixedly connected to the back of the inner wall of the fan hopper 211. A dustproof component 3 is installed on the inner side of the first support assembly 2. The dustproof component 3 includes a dustproof net 301. A handle block 302 is fixedly connected to the front of the dustproof net 301, and a second magnetic block 303 is fixedly connected to the back of the dustproof net 301.

[0031] The positioning groove 203 and the mounting groove 204 are both compatible with the dustproof net 301. The dustproof component 3 passes through the mounting groove 204 and slides into the fan housing 211 along the positioning groove 203. The magnetic poles of the first magnetic block 205 and the second magnetic block 303 are opposite and attract each other, so that the dustproof net 301 is stably installed inside the fan housing 211.

[0032] The refrigeration assembly 7 includes a refrigeration box 701 fixedly connected to the top of the second support frame 5. A thermoelectric cooler 702 is mounted on the top of the refrigeration box 701, and a temperature sensor 703 is mounted on the left side of the refrigeration box 701. The refrigeration box 701, the thermoelectric cooler 702, and the temperature sensor 703 are electrically connected to a power source.

[0033] When the ambient temperature is too high and the cooling water cannot be cooled by the heat dissipation component 4, the thermoelectric cooler 702 is activated. The cooling surface at the bottom of the thermoelectric cooler 702 cools the cooling water inside the cooling chamber 701, while the top of the thermoelectric cooler 702 serves as the heat dissipation surface, thus achieving rapid cooling of the cooling water. The cooling water cooled by the cooling component 7 is then pumped into the sample water cooler body 102 by the circulating water pump 6, greatly improving the cooling efficiency of the cooling water. Furthermore, the temperature sensor 703 monitors the water temperature inside the cooling chamber 701. When the water temperature falls below the set range, the thermoelectric cooler 702 stops working.

[0034] The filter element 801 is detachably installed on the top of the inner wall of the filter assembly 8.

[0035] The filter element 801 can filter out impurities such as rust residue generated on the inner wall of the sample water cooler body 102 in the cooling water, thereby improving water quality and preventing impurities from clogging other components.

[0036] Working principle and usage process of this utility model:

[0037] The sample water is located inside the sample water pipe 103 and flows through the sample water cooler body 102. The sample water inside the sample water pipe 103 and the cooling water inside the sample water cooler body 102 are cooled through heat exchange, so that the temperature of the sample water is maintained at about 30°C, thereby meeting the testing requirements.

[0038] When the cooling water inside the sample water cooler body 102 is used for a long time, its temperature will gradually increase, and then the temperature difference between the cooling water and the sample water will decrease, which will reduce the heat exchange efficiency and thus reduce the cooling efficiency of the sample water.

[0039] The circulating water pump 6 is started to drive the cooling water to flow. The cooling water passes through the filter assembly 8, the refrigeration assembly 7, and the circulating water pump 6 in sequence through the right side of the sample water cooler body 102 and enters the cooling water hole of the first heat sink 402. The first heat sink 402 has a large contact area with the air and has good thermal conductivity, so it can transfer the heat of the cooling water to the nearby air. The cooling fan 202 is started to accelerate the air flow and drive the air to flow upward, which can blow away the hot air near the heat sink 4, thereby achieving air cooling and cooling of the cooling water. The cooled water returns to the interior of the sample water cooler body 102 from the left side, thereby increasing the temperature difference between the cooling water and the sample water and improving the cooling efficiency of the sample water.

[0040] When the ambient temperature is too high and the cooling water cannot be cooled by the heat dissipation component 4, the thermoelectric cooler 702 is activated. The cooling surface at the bottom of the thermoelectric cooler 702 cools the cooling water inside the cooling chamber 701, while the top of the thermoelectric cooler 702 serves as the heat dissipation surface, thus achieving rapid cooling of the cooling water. The cooling water cooled by the cooling component 7 is then pumped into the sample water cooler body 102 by the circulating water pump 6, greatly improving the cooling efficiency of the cooling water. Furthermore, the temperature sensor 703 monitors the water temperature inside the cooling chamber 701. When the water temperature falls below the set range, the thermoelectric cooler 702 stops working.
