Abstract

The invention relates to the technical field of hot waste water recovery, in particular to a sewage heat energy recovery system. According to the system, heat energy recovery is realized by arranging a heat exchanging device which comprises a filtering device and a plurality of groups of heat exchangers, conducting filtering and recovery of the hot waste water, and arranging a corrugated heat exchanging tube to realize heat exchange of the hot waste water and normal temperature clean water. Compared with a traditional heat exchanging device, tubes communicating with the starting end heat exchanger and ending end heat exchanger are additionally arranged, so as to realize gradual temperature rising and heat exchanging of the normal temperature clean water and the hot waste water and improve heat exchanging efficiency, and in order to clean waste in the heat exchanger more efficiently, the heat exchanger is filled with filtering board with alumina balls which are driven by back washing water, so as to conduct filtering to the hot waste water, enable the waste not to enter in the heat exchanger, and improve the exchanging efficiency of the heat exchanger. The system can recover waste heat energy and save a large amount of water resource.

Description

technical field [0001] The invention relates to the technical field of sewage heat energy recovery, in particular to a sewage heat energy recovery system. Background technique [0002] Wastewater recycling can produce huge economic and social benefits, save a lot of energy, and play an important role in protecting the environment. Domestic waste heat recovery generally adopts heat exchange equipment including heat exchangers. For the waste heat in sewage, for example, the hot sewage discharged from schools, institutions, hotels and bathing places with central heating is simply filtered to remove most of the coarser impurities and then enters the heat exchange equipment for heat exchange. There are still large particles of impurities and suspended Impurities can clog the heat exchanger. contamination and wear and tear. In order to ensure the normal operation of the heat exchanger, it is necessary to clean the filter, heat exchanger and pipes regularly, which not only consu...
