The second outlet of the heat exchanger 2 is connected to the fourth pipeline 10, and the fourth pipeline 10 is respectively connected to the condensed water output pipe 11 and the cooling water input pipe 9.

[0018] Working principle:

[0019] During normal use, the purified water stored in the storage water tank 1 is pumped to the distribution pipeline 5 along the first pipeline 3 by the circulating water pump 4, and then transported to each use point through each use node pipeline 20 of the distribution pipeline 5; and the remaining purified water is transported to the storage water tank 1 again along the second pipeline 6 after passing through the heat exchanger 2. During the whole process, the purified water can always circulate, so as to effectively ensure that the purified water always maintains a high water quality to meet the needs of pharmaceutical production; and in this process, high-temperature steam can be transported to the third pipeline 7 through the steam input pipe 8 and enter the heat exchanger 2, so as to exchange heat with the purified water flowing in the heat exchanger 2, so as to achieve heating and disinfection of the purified water to further ensure the quality of the purified water. After the heating and disinfection treatment, the cooling water can be directly transported to the fourth pipeline 10 through the cooling water input pipe 9, so as to achieve rapid cooling of the circulating purified water to ensure the normal use of the purified water, and also to achieve pasteurization of the purified water.

[0021] During the circulation of purified water, the circulating purified water can be randomly tested through the first sample detection pipeline 15. If it is detected that the water quality of the purified water is unqualified, the control valve 13 can be controlled to close and the drainage control valve 16 on the discharge pipeline 14 can be opened, so that the purified water in the entire circulation pipeline can be directly discharged, and the subsequently produced purified water will continue to be transported along the delivery pipeline to the storage water tank 1, thereby further ensuring the outlet water quality of the purified water.
