Embodiment 1

[0021] Example 1. like figure 1 As shown, the thermal energy recovery treatment device of the present invention includes a coarse filter 1 and a plate heat exchanger 2, and the coarse filter 1 adopts a belt filter or other filters. After the coarse filter 1, a rotary disc filter 14 and a precision filter 3 are housed, and the precision filter has another name called a high-precision microporous filter, which is a commercially available conventional product. The precision filter 3 is connected to the plate heat exchanger 2 through the hot water pump 4; on the upper part of the plate heat exchanger 2, there is a hot clean water discharge port 5, which is connected to the hot water use equipment 15 and the hot clean water storage tank 16. A cold water inlet pipe 6 and a sewage discharge pipe 7 are connected to the bottom of the plate heat exchanger 2; a clean water backwash pipe 8 is connected to the sewage discharge pipe 7, and the clean water backwash pipe 8 communicates with ...

Abstract

The invention discloses a recovery processing method and a recovery processing device of heat energy. The method comprises the following steps: high-temperature hot wastewater is delivered to a heat exchanger after being filtered by a filter device, and exchanges heat with cold clear water entering the heat exchanger at the same time; the high-temperature wastewater after heat exchange becomes ambient temperature wastewater to be treated; and the cold clear water becomes hot clear water after heat exchange, and is delivered to equipment using hot water to be used as supplementary hot water. The device of the invention can recycle heat energy in large amount of high-temperature hot wastewater generated in production process so as to reduce cost of enterprises, and is mainly used for recovering the heat energy in the high-temperature hot wastewater of workshops. Each workshop can use one recovery device for heat energy for one or more hot wastewater draining equipment according to conditions of hot wastewater draining points.

Description

technical field [0001] The invention relates to a heat recovery treatment method and a recovery treatment device. Background technique [0002] In the production process of printing and dyeing enterprises, a large amount of high-temperature hot wastewater will be generated. At present, the treatment of this kind of hot wastewater is usually directly discharged after treatment, and the heat energy in the hot wastewater cannot be recycled, resulting in a large waste of heat. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a heat recovery treatment method and a heat recovery treatment device, which can recycle and utilize the heat energy in a large amount of high-temperature hot wastewater generated in the production process, and reduce the cost of the enterprise. [0004] In order to solve the above technical problems, the technical solution of the present invention is a heat recovery treatment method. It uses fil...
