Abstract

The invention discloses a waste heat recovering system capable of continuously generating steam aiming at impure waste water resources. The system comprises a second-type absorption heat pump, a front water tank, a filtering device, a water pump and a plate type heat exchanging device, wherein cooling water is input into a condenser of the second-type absorption heat pump and is output after heat exchanging, the output end of an evaporator is connected with the input end of a generator, the output end of the generator is connected with the plate type heat exchanging device, tap water is input into the evaporator and forms circulating water through the evaporator, the generator, the water pump and the plate type heat exchanging device, discontinuous waste hot water is changed into continuous waste hot water through the front water tank, input into the plate type heat exchanging device after impurities are filtered out through the filtering device, and then discharged as low-temperature waste hot water through heat exchanging. Low-temperature clear water is input into an absorber after passing through the water pump, and then is output as steam needed by a user. The system has the advantages that the utilization rate of the waste hot water is high, and the steam generating efficiency is high.

Description

technical field

[0001] The invention relates to a waste heat recovery device of a printing and dyeing factory, in particular to a waste heat recovery system for continuously producing steam aimed at waste water containing impurities. Background technique

[0002] The low-temperature exhaust gas from the printing and dyeing factory will cause huge heat loss through the treatment system or direct discharge, which makes the energy utilization rate of the printing and dyeing factory low, which not only causes a lot of energy waste, but also seriously pollutes the environment. Exhaust gas emission from printing and dyeing factories is a common problem in our country and even in the world. However, with the development of heat pump technology, especially the advent of large-scale high-temperature water-source heat pumps, the recovery of waste heat from low-temperature exhaust gas in printing and dyeing plants will become possible. In addition, the absorption heat pump type relies...
