[0023] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Please refer to Figure 1 As a specific implementation method, the technical solution of this utility model is as follows: a circulating water replenishment device, comprising: a first recovery tank 5, a first cooling tower 4 disposed on the top of the first recovery tank 5, the first cooling tower comprising a heat exchange chamber 43, the bottom of the heat exchange chamber 43 being provided with an outlet 430 communicating with the interior of the first recovery tank 5, the side wall of the heat exchange chamber 43 being provided with a second inlet 42 communicating with the outside, the heat exchange chamber 43 being provided with a first heat exchange pipe 401, the first recovery tank 5 being provided with a third outlet 51, and the third outlet 51 being connected to a first pump 6.

[0025] For details, please refer to Figures 1-6The technical solution of this application is as follows: It includes a first recovery tank 5, which is a rectangular box structure; a first cooling tower 4 includes a tower body, within which a heat exchange chamber 43 is formed; the heat exchange chamber 43 is provided with a second inlet 42, which is connected to a connection port 1. In specific use, it recovers condensate or water vapor generated in the factory production workshop. Condensate generated from showers in the factory's living area and condensate generated from heating in the factory's living area are collected using collection tanks. After collection, the condensate flows into the heat exchange chamber 43 through the second inlet 42. Steam generated in the factory is transported to the heat exchange chamber 43 through a pipeline connected to the second inlet 42. A heat exchange tube 401 is connected to a tap water source. After the tap water flows through the first heat exchange tube 401, it exchanges heat with the steam inside the heat exchange chamber 43, causing the steam to condense into condensate. The condensate is collected and flows from the outlet 430 at the bottom to the first collection tank for collection. In use, the condensate can be pumped out by the first pump 6. The other end of the first pump 6 is connected to a heat exchange radiator that cools the rotating parts of various rotating machinery, providing cooling water to the heat exchanger. This allows the steam and condensate generated in the factory to be collected for use in the heat exchanger, saving energy, increasing the service life of equipment in the production workshop, and reducing the water treatment cost of circulating water.

[0026] Furthermore, along the vertical direction, below the second inlet 42, at least two first partitions 44 are spaced apart on the first sidewall of the heat exchange chamber 43. The first partitions 44 extend from their first extension ends away from the first sidewall to the second sidewall opposite to the first sidewall. At least two second partitions 45 are alternately arranged on the second sidewall with the first partitions 44. The second extension ends of the second partitions 45 extend from their second extension ends away from the second sidewall towards the first sidewall. The two sides of the first partitions 44 and the second partitions 45 are connected to the two sidewalls of the heat exchange chamber 43 adjacent to the first and second sidewalls.

[0027] For details, please refer to Figure 5 , Figure 6 The first cooling tower 4 includes a rectangular tower body with an outlet 430 located at the bottom. First and second sidewalls are arranged opposite each other. Two first baffles 44 are spaced apart on the first sidewall, and two second baffles 45 are also arranged on the second sidewall, alternating from bottom to top. A second inlet 42 is located on the second sidewall above the second baffles 45. The outlet 430 is located near the first sidewall. A first heat exchange tube 401 extends from below the lowest first baffle 44 along the extension direction of the first baffle 44, then passes around the end of the second baffle 45 and continues along the extension direction of the second baffle 45. After passing around both first baffles 44 and second baffles 45, the upper end extends out of the tower body and connects to the first outlet 40. The other end of the first heat exchange tube 401 connects to the first inlet 41. During operation, steam enters from the second inlet 42 and flows along... Figure 7The water flows in the middle direction 420, and the first inlet 41 is connected to the tap water source. After passing through the first heat exchange tube 401, the tap water flows out from the first outlet 40 to achieve heat exchange, thereby condensing the steam into condensate water which flows out from the outlet 430 and is collected in the first recovery tank 5.

[0028] Furthermore, as a specific implementation, in the vertical direction, the first extension end is not higher than the end of the first partition 44 connected to the first sidewall; the second extension end is not higher than the end of the second partition 45 connected to the second sidewall. Specifically, with this arrangement, condensate can flow up and down from the first partition 44 and the second partition 45 after it is generated, facilitating the collection of condensate.

[0029] Further, in a preferred embodiment, the first extension end is lower than the end of the first partition 44 connected to the first sidewall, and the second extension end is lower than the end of the second partition 45 connected to the second sidewall. (See reference) Figure 7 By tilting the first baffle 44 and the second baffle 45, it is easier for the condensate to flow downward.

[0030] Furthermore, as a specific implementation, the first sidewall and the second sidewall are arranged vertically and parallel to each other, the outlet 430 is close to the first sidewall and parallel to the first sidewall, and the first partition 44 is above the outlet 430.

[0031] Further, refer to Figure 4 , Figure 5 The heat exchange tubes consist of three parallel and spaced tubes, which achieves better heat exchange performance.

[0032] Furthermore, as a specific implementation method, refer to Figures 2-6The first recovery tank 5 has a third inlet 50 on its side wall for connecting to the outlet of the heat exchanger. It also includes a second recovery tank 8, with a second cooling tower 7 at its top. The second cooling tower 7 contains a second heat exchange tube 701 and a third heat exchange tube 702, which are thermally coupled together. The second heat exchange tube 701 includes a fourth inlet 70 connected to the outlet of the first pump 6, and the other end of the second heat exchange tube 701 is connected to the second recovery tank 8. The first recovery tank 5 has a third inlet 50 on its side wall for connecting to the outlet of the heat exchanger. After heat exchange in the heat exchanger, the condensate with a higher temperature flows back into the first recovery tank 5. The second recovery tank 5 also includes a second recovery tank 8 and a second cooling tower 7. During operation, the pump outlet of the first pump 6 is connected to the fourth inlet 70 of the second heat exchange tube 701. The second cooling tower 7 also includes a third heat exchange tube 702, one end of which is connected to tap water. Tap water flows through the third heat exchange tube 702 and... The condensate in the second heat exchange tube 701 exchanges heat and cools the condensate in the first collection tank. The fifth outlet 81 is connected to the second pump 9. The pump outlet of the second pump 9 is connected to the liquid inlet of the heat exchanger, which pumps the condensate in the second collection tank to the heat exchanger. After passing through the heat exchanger, the condensate flows back to the first recovery tank 5. Then, the first pump 6 pumps it to the second cooling tower 7 for cooling and collection in the second recovery tank 8. This process is repeated to provide condensate to the heat exchanger, thereby achieving the purpose of cooling the rotating mechanical parts of the equipment in the factory.

[0033] Furthermore, the second recovery tank 8 is provided with a fifth outlet 81, and the fifth outlet 81 is provided with a second pump 9. The pump outlet of the second pump 9 is used to connect with the liquid inlet of the heat exchanger.

[0034] Furthermore, the first heat exchange tube 401, the second heat exchange tube 701, and the third heat exchange tube 702 are all made of copper. Specifically, copper has good thermal conductivity, which can achieve better heat exchange effect.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
