Abstract

The invention discloses a recovery device for waste heat of waste water. The recovery device is innovative in that the recovery device comprises a high-temperature wastewater pool, a sewage pump, a sewage pre-processor, a filter tank, a first-stage heat exchanger, a second-stage heat exchanger, a heat pump, a cold water tank A, a cold water tank B, a hot water tank and a low-temperature wastewater pool; the high-temperature wastewater pool is connected with the filter tank by means of the sewage pre-processor; the filter tank is connected with the first-stage heat exchanger by means of a pipeline; the first-stage heat exchanger is connected with the cold water tank A, the hot water tank and the second-stage heat exchanger; the second-stage heat exchanger is connected with the low-temperature wastewater pool and the heat pump; an evaporator and a condenser are arranged in the heat pump; a compressor and a throttle valve are arranged between the evaporator and the condenser; and one end of the condenser is connected with the cold tank B and the other end of the condenser is connected with the hot water tank. The recovery device for waste heat of waste water has following advantages: by means of two stages of heat exchangers, heat exchange of waste water is performed so that higher utilization efficiency of waste heat is obtained; and waste water is pre-processed before flowing into heat exchangers in order to reduce water dirt staying in the heat exchangers and therefore working efficiency of the heat exchangers is not reduced.

Description

technical field [0001] The invention relates to the field of waste heat recovery, in particular to a waste heat recovery device for waste water, which belongs to the technical field of heat recovery equipment. Background technique [0002] In daily life and industrial production, a lot of waste hot water is often discharged directly, which not only causes a lot of waste of resources, but also directly exchanges heat with the air, causing heat pollution. In the promotion of low-carbon environmental protection Today waste heat recovery from wastewater is absolutely necessary. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a wastewater waste heat recovery device which has a reasonable structure and can fully recover the heat of the wastewater. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A waste heat recovery devi...
