Description
Technical field
The present invention relates to waste water heat recovery technology, more particularly, to a kind of dining room automatic converting apparatus of cooking stove used heat.
Background technology
At present, hotel, restaurant etc. commonly use for culinary art combustion gas or fuel oil Chinese meal stove, the most all can
Producing substantial amounts of high-temperature residual heat and high-temperature tail gas, it is direct from the chamber of a kitchen range that these high-temperature residual heats and high-temperature tail gas generally are had no to utilize
Surrounding and chimney in exclude, it not only causes the waste of energy, also result in the pollution to environment.
Through retrieval, in prior art, the application for a patent for invention of Application No. CN200510102240.3 discloses a kind of ring
Guarantor's type energy-saving water heating system by recovering waste heat of air conditioner, including being provided with the outdoor heat exchanger of refrigerant inlet and refrigerant exit, outdoor exchange
Device includes that heat exchanger, heat exchanger are provided with refrigerant inlet, refrigerant exit, water inlet and outlet, and wherein, water inlet connection carries
For the cold water pipe of cold water, the water supply installation that outlet can outwards supply water by looping back water pipe to connect.Due to through compressor of air conditioner
High temperature refrigerant after compression is lowered the temperature by cold water in a heat exchanger, and air-conditioning, without the most outwardly air heat release, prevents steam from polluting
Environment；Meanwhile, cold water is heated to form hot water in a heat exchanger, needed for supply people's life, work, make use of efficiently
Coolant heat.The utility model patent of Application No. CN201020202335.9 discloses a kind of Chinese meal stove Waste Heat Recovery and utilizes dress
Put, including steam-water separation water tank and waste heat exchanger, it is characterised in that: between described steam-water separation water tank and waste heat exchanger by
Circulating water pipe connects, and is provided with and connects with circulating water pipe between the water inlet of waste heat exchanger and the outlet of steam-water separation water tank
Water pump, steam-water separation water tank connects with steam pipeline.
But, above-mentioned prior art does not all account for the impact that aerator produces during range burner.Such as,
For the unit that currently the crowd is dense boards and lodge and group, such as school, army, prison, hospital etc., dining room cooking stove heat waste and stream
Mistake phenomenon is extremely serious.Owing to the working method of dining room cooking stove is that this mode causes substantial amounts of for for oxygen master with aerator
Heat losses.As a example by a diameter of 80cm cooking stove of dining room, when cooking stove is not switched on aerator aerator, its thermal efficiency may be up to
More than 70%, but the dining room demand to firepower cannot be met.Be typically to increase 550W, flow is 20m3/ minute aerator,
According to airflow balance principle, also can correspondingly give off more than 20m in burner hearth3/ minute the high-temp waste gas of 600-700 DEG C.
Stove thermal efficiency now is only 40%, is equivalent to the heat of about 60% and is discharged along with high-temp waste gas.
