A kitchen flue gas waste heat recovery and utilization system

Abstract

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.
