[0002] The statements in this section are provided only as background information in connection with this disclosure and may not constitute prior art.

[0003] With the rapid development of industrial production, the sterilization and recycling water generated during the production process in high-temperature workshops is often difficult to reuse directly due to its high-temperature characteristics, leading to water waste and increased energy consumption. Currently, the common practice is to supplement the recycled water with tap water to lower its temperature and meet the requirements for reuse. However, this approach not only increases water consumption but also limits the efficiency of water resource utilization.

While this method is simple and easy to implement, it presents the following technical problems: First, the amount of tap water added is large, leading to water waste; second, the cooling effect is limited and cannot meet the requirements of some processes with high water temperature requirements; and third, water quality stability is affected, potentially introducing additional impurities and microorganisms.

The output end of the primary cooling system is connected to the input end of the secondary cooling system. The output end of the secondary cooling system is connected to the input end of the tertiary cooling system. The tap water supply end of the tertiary cooling system is connected to the tap water pipeline. The output end of the tertiary cooling system is connected to the secondary use pipeline in the workshop.

[0024] The secondary cooling system includes: a first cooling tower 2, a first cool water tank 3, and a multi-stage cooling tower system; the output end of the primary cooling system is connected to the input end of the first cooling tower 2, the output end of the first cooling tower 2 is connected to the first input end of the first cool water tank 3, the first output end of the first cool water tank 3 is connected to the input end of the multi-stage cooling tower system, the output end of the multi-stage cooling tower system is connected to the second input end of the first cool water tank 3, and the second output end of the first cool water tank 3 is connected to the input end of the tertiary cooling system.

[0025] In this embodiment, specifically, the primary cooling system is a greywater storage tank 4, the greywater outlet of the sterilization vessel 1 is connected to the input end of the greywater storage tank 4, the output end of the greywater storage tank 4 is connected to the input end of the first cooling tower 2, and the sewage outlet of the greywater storage tank 4 is connected to the sewage pipe.

[0026] In this embodiment, specifically, the three-stage cooling system is a second cooling water tank 5. The second output end of the first cooling water tank 3 is connected to the input end of the second cooling water tank 5. The tap water supply end of the second cooling water tank 5 is connected to the tap water pipe. The output end of the second cooling water tank 5 is connected to the secondary use pipe in the workshop.

[0027] In this embodiment, specifically, the multi-stage cooling tower system includes: multiple cooling towers, the first output end of the first cooling water tank 3 is connected in parallel with the input ends of the multiple cooling towers, and the output ends of the multiple cooling towers are all connected to the second input end of the first cooling water tank 3.

[0028] In this embodiment, specifically, the number of second input terminals of the first cold water pool 3 is consistent with the number of cooling towers in the multi-stage cooling tower system, and the two are set in a one-to-one correspondence.

[0029] In this embodiment, specifically, the multi-stage cooling tower system includes two cooling towers: a second cooling tower 6 and a third cooling tower 7.

[0031] The specific processing flow of the greywater cooling system proposed in this embodiment is as follows:

[0032] The high-temperature return water from the sterilization autoclave 1 enters the greywater storage tank 4 for primary cooling (a corresponding cooling device can be installed in the greywater storage tank 4, or natural cooling can be used without installation). After primary cooling, the greywater enters the first cooling tower 2 for further cooling. The cooled greywater (high water temperature) then enters the first cold water tank 3 for further cooling (a corresponding cooling device can be installed in the first cold water tank 3, or natural cooling can be used without installation). It then enters the second cooling tower 6 and the third cooling tower for further cooling. The cooled greywater (moderate water temperature) then enters the first cold water tank 3 for further cooling. Finally, the cooled greywater enters the second cold water tank 5 and is mixed with tap water for secondary use in the workshop.
