The invention discloses a kitchen fume
waste heat recycling
system. The
system comprises a fume collecting box, a fume purifier, a
temperature difference power generating piece, a storage battery, a gravity
heat pipe heat exchanger, a water tank, an integrated
automatic control device and an
inverter. A multi-time graded treatment manner is adopted, the fume collecting box collects kitchen fume, the fume enters the fume purifier firstly to be subject to oil
stain removal, the manner of one-side
air cooling and one-side
convection heat exchange is adopted for generating power through the
temperature difference power generation module, and the storage battery is connected for electric amount storage. The cooled fume enters an outdoor heat preservation pipeline again to be subject to
heat pipe waste heat recycling, heating of the
automatic control water tank is combined, so that constant-temperature domestic water is obtained, and finally low-temperature fume subject to two-stage heat exchange is discharged out of a fume discharging opening. The
system can sufficiently utilize the characteristics of the
temperature difference power generation and
heat pipe waste heat recycling, temperature difference power generation and heat
pipe waste heat recycling are effectively combined, meanwhile, energy waste and unnecessary equipment arrangement caused by
improper temperature during traditional fume recycling are avoided, and the utilization efficiency and
economic benefits of a kitchen fume discharging system are improved.
