[0015] It should be noted that if the embodiment of the utility model has involved directionality indication (such as up, down, left, right, front, back……), then the directionality indication is only used to explain the relative position relationship, movement condition etc. between the components in a certain specific posture (such as shown in the drawing), if the specific posture changes, then the directionality indication also changes accordingly.
[0016] In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on that ordinary skilled person in the art can realize, when the combination of technical solutions appears mutual contradiction or cannot be realized, it should be considered that the combination of technical solutions does not exist, also not in the protection scope required by the utility model.
[0017] The technical scheme of the utility model will be described clearly and completely in the following by combining with specific embodiments, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor, belong to the protection scope of the utility model.
[0018] Reference Figure 1As shown, the structure of this utility model is as follows: a closed-loop cooling device for demineralized water corrosion prevention and impurity removal, including a water tank 1, a water pump 2, and a plate heat exchanger 3. The water tank 1 is connected to the cooling water outlet of a water vapor sampling device. High-temperature demineralized water from the water vapor sampling device enters the water tank 1 through a pipe. The inlet of the water pump 2 is connected to the water tank 1, and the outlet of the water pump 2 is connected to the inlet of the plate heat exchanger 3. The water pump 2 transports the high-temperature demineralized water from the water tank 1 to the plate heat exchanger 3. An industrial water inlet pipe 4 and an industrial water outlet pipe 5 are connected to the plate heat exchanger 3. Industrial water enters the plate heat exchanger 3 through the industrial water inlet pipe 4. After circulating in the plate heat exchanger 3, the industrial water is discharged from the industrial water outlet pipe 5. The demineralized water with a higher temperature exchanges heat with the industrial water in the plate heat exchanger 3 and is then cooled down. The outlet of the plate heat exchanger 3 is connected to the cooling water inlet of the water vapor sampling device. After being cooled, the demineralized water re-enters the water vapor sampling device as cooling water to lower the temperature of the sample water and provide a reliable environment for subsequent instrument measurements. As the temperature of the sample water decreases, the temperature of the demineralized water increases and is transported back to the water tank 1, and this process is repeated.
[0019] In this embodiment, a Y-type filter 6 is connected to both the water inlet end of the water pump 2 and the industrial water inlet pipe 4. The Y-type filter 6 filters out large particulate impurities in the demineralized water and industrial water, preventing impurities from clogging the Y-type filter 6 and reducing the heat exchange efficiency. The filter device of the Y-type filter 6 is a filter screen. When the pore size of the impurities is larger than the pore size of the Y-type filter 6, the impurities will be blocked on one side of the filter screen to achieve the purpose of purifying the water quality.
[0020] like Figure 1 As shown, a check valve 7 is provided at the outlet of water pump 2. The check valve 7 is used to prevent the backflow of demineralized water from impacting the impeller of water pump 2. When water pump 2 suddenly stops running, the pressure inside water pump 2 disappears, and the demineralized water in the pipe connected to the outlet of water pump 2 will flow back to water pump 2. The check valve 7 is installed at the outlet of water pump 2 to prevent the demineralized water from flowing back to water pump 2, protect the centrifugal pump, and prevent damage caused by the backflow of demineralized water.
[0021] Furthermore, a water supply pipe 8 is connected to the water tank 1, and a float valve 9 connected to the water supply pipe 8 is installed inside the water tank 1. The float valve 9 is mainly used to control the water level in the water tank 1. When the water level of the demineralized water in the water tank 1 is low, the float valve 9 opens and automatically adds demineralized water into the water tank 1 through the water supply pipe 8. When there is enough demineralized water in the water tank 1, the float valve 9 closes and the water supply pipe 8 stops adding demineralized water into the water tank 1.
[0022] Furthermore, a drain pipe 10 is provided at the bottom of the water tank 1. The drain pipe 10 is used to discharge impurities and dirt inside the water tank 1 to prevent scale and impurities from accumulating and damaging the water tank 1.
[0023] Further, the high point in the water tank 1 is provided with overflow pipe 11, overflow pipe 11 and blowdown pipe 10 communication, overflow pipe 11 for preventing water tank 1 overflow, warning level, ventilation and balance pressure; when the water level in the water tank 1 exceeds the set value, the excess liquid in the water tank 1 from the overflow pipe 11, through the blowdown pipe 10 to the designated location, thereby protecting the equipment and the surrounding environment.
[0024] In particular use, the temperature of the water vapor sampling device is higher than that of the water tank 1, and the water pump 2 is transported to the plate heat exchanger 3 inside the plate heat exchanger 3. Industrial water enters the plate heat exchanger 3 through the industrial water inlet pipe 4, and the industrial water is circulated in the plate heat exchanger 3 and then discharged from the industrial water outlet pipe 5. The temperature of the high-temperature desalted water is lowered by heat exchange with the industrial water in the plate heat exchanger 3. The cooled desalted water enters the water vapor sampling device again as cooling water to reduce the temperature of the sample water and provide a reliable environment for subsequent instrument measurement. The temperature of the sample water is lowered while the temperature of the desalted water is raised, and it is transported back to the water tank 1 for circulation.
[0025] The above describes the utility model with specific examples, but it should be understood that the specific description should not be understood as limiting the essence and scope of the utility model. Various modifications made by those skilled in the art after reading the specification are within the scope of the utility model.
