Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] See also Figures 1 to 4The utility model provides a technical solution: a water vapor recompression evaporation system, including a balance tank body 3, a top plate 13 is provided on the upper end of the balance tank body 3, and the upper part of the top plate 13 is connected to the filter box 6 through a pipeline, a first filter element 19 is provided inside the filter box 6, and first limiting fences 18 are provided on both sides of the first filter element 19, and the first limiting fence 18 is fixed in the filter box 6, a second filter element 21 is provided inside the filter box 6, and the second filter element 21 is an activated carbon adsorption layer.

[0029] In a specific embodiment of the present utility model, a top plate 13 is provided at the upper end of the balancing tank body 3 for installing a filter box 6. The upper part of the top plate 13 is connected to the filter box 6 through a pipeline for filtering and purifying the input water source raw material. A first filter element 19 is provided inside the filter box 6 for filtering out large particulate impurities contained in the raw material to prevent clogging of the pipeline. First limiting fences 18 are provided on both sides of the first filter element 19. The first limiting fence 18 is fixed in the filter box 6 for limiting the first filter element 19. A second filter element 21 is further provided inside the filter box 6. The second filter element 21 is an activated carbon adsorption layer for filtering and adsorbing the raw material and adsorbing the odor contained therein. Second limiting fences 20 are provided on both sides of the second filter element 21. The second limiting fence 20 is fixed in the filter box 6 for limiting the second filter element 21. It should be explained that the structures of the first limiting fence 18 and the second limiting fence 20 are as shown in FIG. Figure 3 As shown, there are several circular holes opened at intervals on it, which can ensure the normal circulation of the water source raw material and also stabilize the flow rate of the water source raw material flowing into the filter box 6.

[0030] In addition, a rubber pad 7 is provided on the upper end of the filter box 6 to improve the sealing between the cover 8 and the filter box 6. A cover 8 is removably provided on the upper end of the rubber pad 7, which is convenient for personnel to open and replace various filter elements inside, and clean up impurities filtered out inside. A first valve 5 is connected to one side of the filter box 6 through a pipeline to control whether the raw materials pass through and the flow rate of the water source raw materials.

[0031] Specifically, a fixing ring 12 is detachably fixed to the periphery of the through-hole in the middle of the top plate 13 by bolts, and a first sealing ring 2 is provided between the fixing ring 12 and the top plate 13 .

[0032] In order to solve the problem that the balance tank is not easily damaged, such as Figure 1As shown, a fixing ring 12 is detachably fixed to the outer periphery of the through-hole in the middle of the top plate 13 by bolts for the subsequent installation of the flange. It should be noted that if the flange is directly connected to the balancing tank body 3, then the subsequent disassembly and replacement of the flange will cause damage to the balancing tank body 3 (for example, the flange is directly connected to the balancing tank body 3 by bolting, then during the disassembly process, the bolting holes opened on the top of the balancing tank body 3 will be worn to a certain extent, thereby affecting the air tightness inside the balancing tank body 3). Therefore, by connecting the fixing ring 12 fixed to the outer periphery of the through-hole in the middle with external components, the structure of the balancing tank body 3 can be further protected. At the same time, a first sealing ring 2 is provided between the fixing ring 12 and the top plate 13 to improve the sealing between the connecting parts.

By removing the sealing plate 9, it is convenient for technicians to clean the interior of the balancing tank body 3 through the through circular hole in the middle of the top plate 13.

[0035] Specifically, a second flange 15 is provided around the through circular hole at the bottom of the balancing tank body 3. The bottom of the second flange 15 is detachably connected to a third flange 17 by bolts. A third sealing ring 16 is provided between the second flange 15 and the third flange 17. The bottom end of the third flange 17 is connected to a second valve 14 through a pipeline.

[0036] In order to solve the problem of internal and external connectivity, such as Figure 2 As shown, a second flange 15 is provided at the through hole at the bottom of the balancing tank body 3 , and the through hole at the bottom of the balancing tank body 3 is communicated with the interior of the balancing tank body 3 , so as to achieve internal and external communication of the balancing tank body 3 .

[0037] In order to solve the problem of improving the sealing between flanges and the flow of raw materials, such as Figure 1 、 2 As shown, the bottom of the second flange 15 is detachably connected to the third flange 17 by bolts, and a third sealing ring 16 is provided between the second flange 15 and the third flange 17. The connection of the flanges improves the splicing performance between the pipelines. The provision of the third sealing ring 16 improves the sealing performance between the flanges to prevent leakage of raw materials. The bottom end of the third flange 17 is connected to the second valve 14 through a pipeline. The opening and closing of the second valve 14 is used to control whether the raw materials pass through and the flow rate of the raw materials.

[0038] Specifically, the free end of the pipe provided with the second valve 14 is connected to the bottom of the heating box 23 , and a plurality of heating wire assemblies 26 are provided inside the heating box 23 .

[0039] In order to solve the problem of heating raw materials, such as Figure 1 、 4 As shown, one end of the pipeline where the second valve 14 is located is connected to the bottom of the balancing tank body 3, and the other end is connected to the bottom of the heating box 23, so that the raw materials enter from the bottom, which is beneficial to increase the residence time of the raw materials inside the heating wire assembly 26. A plurality of heating wire assemblies 26 are provided inside the heating box 23 for heating the raw materials.

[0040] Specifically, an outlet 25 is provided at the upper end of the heating box 23 , a temperature sensor 24 is provided on one side of the outlet 25 , and a controller 22 is provided on one side of the heating box 23 .

[0041] In order to solve the problem of detecting the temperature of discharged raw materials, such as Figure 1 As shown, an outlet 25 is provided at the upper end of the heating box 23, and a temperature sensor 24 is provided on one side of the outlet 25 for detecting the temperature of the discharged raw materials. A controller 22 is provided on one side of the heating box 23, and the controller 22 is electrically connected to the electrical equipment of the device and monitors and controls its temperature.

[0042] Specifically, a support ring 4 is fixed to the periphery of the balancing tank body 3 , and a plurality of legs 1 are provided at the bottom end of the support ring 4 .

[0043] In order to solve problems such as Figure 1 As shown, a support ring 4 is fixed to the periphery of the balancing tank body 3 for installing the support legs 1. Several support legs 1 are provided at the bottom end of the support ring 4 to support the entire device.

[0044] The specific implementation methods disclosed herein omit detailed descriptions of known functions and components. To ensure the compatibility of the equipment, the operating methods adopted are consistent with the parameters of commercially available equipment.

[0045] In summary, the working principle and usage process of this utility model are as follows:

[0046] First, the water source raw material is sent into the filter box 6 by opening the first valve 5, and then the first filter element 19 and the second filter element 21 arranged inside the water source raw material are used to remove impurities and absorb odors. Then, it flows into the balancing tank body 3 to stabilize the pressure fluctuation, and then flows into the pipeline connected to the heating box 23 through the second flange 15 and the third flange 17 at the bottom of the balancing tank body 3. At this time, the second valve 14 is also in the open state. After the filtered water source raw material enters the heating box, it is heated by the heating wire assembly 26. At the same time, in order to ensure the stability of the heating, a temperature sensor 24 is also provided at the outlet 25 at the upper end of the heating box 23 to control its heating stability.

[0047] In addition, in order to facilitate the installation and disassembly of the top parts of the balancing tank body 3, a fixing ring 12 is detachably fixed to the outer periphery of the through-hole in the middle of the top plate 13 of the balancing tank body 3 by bolts. The fixing ring 12 is used to connect with other components to prevent damage to the balancing tank body 3. At the same time, the through-hole in the middle of the top plate 13 can also be sealed by the first flange 11, the second sealing ring 10 and the sealing plate 9 thereon. When cleaning and maintenance are required, the sealing plate 9 can be opened to facilitate the operation of technicians.
