Waste water heat energy recycling equipment

Abstract

The invention discloses a waste water heat energy recycling equipment and particularly relates to the energy saving technology of recycling and reusing heat energy. The waste water heat energy recycling equipment comprises a centrifugal filtering device, a particle filtering device A, a particle filtering device B, a heat exchange unit and a cumulative heat meter. The problems about waste heat recycling, waste water filtering, filter backflushing water and saving amount display and confirmation and the like are taken into consideration, heat exchange between cold water and hot waste water discharged from factories and buildings is realized by the centrifugal filter, the particle filters, the heat exchangers and the advanced fuel saving amount device, and heat energy in the hot waste water can heat the cold water, therefore, energy is saved and environment is protected.

Description

[0001] technical field [0002] The invention relates to heat energy recovery and reuse energy-saving technology, in particular to a heat recovery device for recovering heat from waste water. Background technique [0003] At present, under the excellent situation that the country is vigorously promoting the "energy saving and emission reduction" plan, the development and development of some energy-saving equipment is continuously carried out, especially for the recovery and reuse of heat energy in the hot wastewater discharged from factories and buildings, such as heat pumps commonly used in buildings Technology, factory heat exchangers and heat exchange equipment, etc., but heat pump technology is mainly used to produce hot water. In the field of heat recovery, it cannot produce obvious economic benefits because of the large power consumption required for its operation. However, heat exchangers and heat exchange equipment commonly used in China for waste heat recovery can p...

Problems solved by technology

[0003] At present, under the excellent situation that the country is vigorously promoting the "energy saving and emission reduction" plan, the development and research of some energy-saving equipment is continuously carried out, especially for the recovery and reuse of heat energy in the hot wastewater discharged from factories and buildings, such as heat pumps commonly used in buildings Technology, factory heat exchangers and heat exchange equipment, etc., but heat pump technology is mainly used to produce hot water. In the field of heat recovery, it cannot produce obvious economic benefits due to the large power consumption required in the operation process.

However, heat exchangers and heat exchange equipment commonly used in China for waste heat recovery can produce obvious economic and environmental benefits in theory, but the removal of large particles and suspended impurities in wastewater, the reasonable selection of filters and the control of backwashing process , blockage and pollution of the heat exchange unit, as well as technical problems such as confirmation of the operation performance and energy saving of the entire system, etc., all need to find a better solution
