[0020] The problem to be solved by the utility model is to provide an industrial high-temperature water waste heat utilization system which has stable operation, reduces costs and increases utilization rate.

[0021] like Figure 1 As shown, in order to ensure stable operation, high working efficiency and reduced costs during use, the utility model relates to an industrial high-temperature water waste heat utilization system, including:

[0022] Hot water buffer tank 1, heat core heat storage module 2, waste heat heating module 3, hot water replenishment module 4;

[0023] The waste heat heating module 3 is provided with an insulation pipe 5; the end of the insulation pipe 5 is connected to the hot water buffer tank 1; the hot water replenishment module 4 is provided with a replenishment pipe 6; the end of the replenishment pipe 6 is connected to the hot water buffer tank 1; the heat core heat storage module 2 is provided with a heating pipe 7; the end of the heating pipe 7 is connected to the hot water replenishment module 2; the heating pipe 7 is provided with a regulating valve 8.

[0024] The beneficial effect of the utility model is that, through the design of the waste heat heating module 3, the heat energy in the production wastewater is fully utilized for recycling and reuse, which saves resources and reduces energy consumption. In addition, the design of the supplementary water supply pipeline 12 is not affected by waste heat conditions and can be used in extremely low temperature weather. It has stable usability and strong practicality.

[0025] Furthermore, the waste heat heating module 3 is provided with a first plate heat exchanger 9; the first plate heat exchanger 9 is provided with a waste heat inlet pipe 10 and a normal temperature inlet pipe 11; the waste heat inlet pipe 10 and the normal temperature inlet pipe 11 are arranged at the left end of the first plate heat exchanger 9. The design of the waste heat inlet pipe 10 ensures that high-temperature water can stably enter the plate heat exchanger for heat exchange.

[0026] Furthermore, a supplementary water supply pipe 12 is provided on the first plate heat exchanger 9, and the end of the supplementary water supply pipe 12 is connected to the hot water buffer tank 1. The design of the supplementary water supply pipe 12 ensures the overall stability and the overall water output effect.

[0027] Furthermore, the waste heat inlet pipe 10 and the supplementary water supply pipe 12 are provided with a switch valve 13. Through the design of the switch valve 13, different numbers of pipes can be freely opened for operation according to needs.

[0028] Furthermore, the hot water replenishment module 4 is provided with a second plate heat exchanger 14; the second plate heat exchanger 14 is provided with a second replenishment water supply pipeline 15; the end of the second replenishment water supply pipeline 15 is connected to the hot water buffer tank 1. The design of the hot water replenishment module 4 ensures a stable supply of hot water.

[0029] Furthermore, the heat core heat storage module 2 is provided with a heat charging pipe 16, and the heat charging pipe 16 is provided with a charger 17. Through the design of the charger 17, the heat core heat storage module 2 is stored with energy under valley power conditions.

[0030] Further, a temperature display 18 is provided on the heat charging pipe 16. Through the design of the temperature display 18, the temperature is controlled at all times.

[0031] Furthermore, a high-level water tank 19 is provided on the heating pipe 7. Heat is exchanged with the interior of the heat core heat storage module 2 through the high-level water tank 19.

In order to fully meet the terminal heat demand and maintain stability, it can be used whenever it is turned on and is not affected by waste heat conditions. A supplementary water supply pipe 12 is further added. When the amount of industrial high-temperature water is insufficient or the heat energy is insufficient, water of a certain temperature is input through the normal temperature inlet pipe 11 and input into the hot water buffer tank 1 through the supplementary water supply pipe 12 for supplementary use.

And each pipeline is provided with a corresponding regulating valve 8 and solenoid valves to ensure the reasonable use of the pipeline.
