The disinfected water is generally at 93 degrees Celsius, and the heat is wasted after discharge. If low-temperature drainage is desired, a cooling water inlet needs to be added to the drainage pipeline to lower the drainage temperature, which would result in water waste.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Figure 1 This is a sterilizer that recovers heat energy and discharges wastewater at low temperatures. Figure 2The diagram shows a heat exchange pipeline. Several disinfection and cleaning pipes are installed inside the chamber 22. A pure water tank 301 is installed at the upper end of the chamber 22. A third pure water valve 7 is installed between the chamber 22 and the pure water tank 301. A heat exchange pipe 27 is installed inside the pure water tank 301. A soft water inlet valve 1 is connected to the upper end of the pure water tank 301. The lower end of the chamber 22 is connected to a wastewater tank 24. A first pure water valve 2 is installed between the chamber 22 and the wastewater tank 24. One end of the wastewater tank 24 is connected to the outlet of the heat exchange pipe 27, and the lower end of the wastewater tank 24 is connected to the inlet of the heat exchange pipe 27. A pipe is installed at the upper end of the wastewater tank 24, and the other end of the pipe is connected to the heat exchange pipe 27. A one-way valve 23 and a second pure water valve 6 are installed on the pipe. A centrifugal pump 19 is installed on the heat exchange pipe 27.

[0019] like Figure 3 As shown, a pipeline control system for recovering heat energy and discharging wastewater at low temperatures includes a chamber 22, a pure water tank 301, and a wastewater tank 24. The pure water tank 301 is located at the upper end of the chamber 22, and the wastewater tank 24 is located at the lower end of the chamber 22. Two peristaltic pumps 16 are connected to one side of the chamber 22 in parallel. The two peristaltic pumps 16 are connected to two liquid level floats 10. A pressure transmitter 12 is installed at the upper end of the chamber 22 and is connected to a circulation pump 18. The circulation pump 18 is connected to the lower end of the chamber 22. An air heating box 25 is installed between the pressure transmitter 12 and the circulation pump 18. The air heating box 25 is connected to a high-efficiency filter 26. A second air pressure switch 13 is installed between the air heating box 25 and the high-efficiency filter 26.

[0020] A sufficiently large wastewater tank is added to the bottom of the equipment, equipped with high and low level floats and platinum resistance thermometers. A pure water tank is located at the top of the equipment, along with a low-head, high-flow centrifugal pump. A sufficiently large heat exchanger tube is installed in the pure water tank, with its outlet connected to the upper part of the wastewater tank and its inlet connected to the outlet of the centrifugal pump via a valve. The bottom of the wastewater tank and the inlet of the centrifugal pump are connected by piping. The water in the pure water tank is preheated to 93 degrees Celsius before the disinfection stage. During disinfection, the water in the pure water tank enters the disinfection chamber. During disinfection, new pure water begins to enter the pure water tank through external piping. After disinfection, the water in the chamber enters the wastewater tank. Then, the sterilizer is cleaned, and the drying stage begins, typically lasting about ten minutes. During this time, the centrifugal pump circulates the hot water from the wastewater tank between the heat exchanger tubes and the wastewater tank, simultaneously heating the water in the pure water tank. When the cleaning and disinfection unit determines that the drying time is up and the water temperature in the wastewater tank has dropped to the specified temperature, the program ends and the water in the wastewater tank is drained.
