When the closed water backwater heat depth utilization user 5 needs to supply heat, the opening of the three-way valve 31 can be adjusted to realize the heat energy utilization of the closed water. For example:
When the heat demand of the closed water backwater heat depth utilization user 5 is small, an inlet end 310, a first water outlet end 311 and a second water outlet end 312 of the three-way valve 31 are opened, the opening degree of the first water outlet end 311 is larger than that of the second water outlet end 312, so that closed water flowing out of a backwater end of the closed water normal backwater user 1 flows through the inlet end 310 and is divided into two paths, one path (more water quantity) flows through the first water outlet end 311, a first pipe 32 and the closed water cooling device 2 in sequence (temperature reduction), and flows into the closed water normal backwater user 1 through a water supply end of the closed water normal backwater user 1 to cool unit equipment; after the other path (smaller water quantity) sequentially flows through the second water outlet 312, the first inlet 41, the first outlet 42, the first pipe 32 and the closed water cooling device 2, the water supply end of the closed water normal backwater user 1 flows into the closed water normal backwater user 1 to cool the unit equipment, meanwhile, in the process that the closed water flows from the first inlet 41 to the first outlet 42, heat exchange is carried out on the plant-area domestic water flowing through the second inlet 43 and the second outlet 44, the temperature of the plant-area domestic water is raised, the plant-area domestic water after the temperature is raised is supplied to the closed water backwater heat deep utilization user 5, and the deep utilization of the closed water recovery heat is realized.

Or, the first water outlet end 311 is directly closed, the second water outlet end 312 is opened, so that the closed water output by the water return end of the closed water normal water return user 1 is subjected to heat exchange by the branch heat exchange equipment 4 and then enters the closed water cooling device 2 for secondary cooling, and the cooled closed water flows into the closed water normal water return user 1 through the water supply end of the closed water normal water return user 1 to cool the unit equipment.
When the heat quantity of the closed water backwater is not required by the user 5, the second water outlet end 312 can be closed, the first water outlet end 311 is opened, and the closed water output by the backwater end of the closed water normal backwater user 1 enters the closed water cooling device 2 through the first water outlet end 311 to be directly cooled and then flows back to the closed water normal backwater user 1.
