The flue gas produced when commercial gas-fired stove cooking, culinary art generally drains into outdoor by enclosure, smoke pipe, blower fan smoke evacuation system, and the high-temperature flue gas of discharge can produce larger impact to surrounding environment, air quality, also often affects the life of surrounding resident.On the other hand, existing catering trade kitchen range are generally that the flame produced by gas combustion is contacted with pan bottom faces and transfers heat to pan, and the temperature flame envelope of flame is the highest, only has at the bottom of a post flame heating kettle, and the utilization rate of heat is relatively low.Flue gas after flame and pan heat exchange still has higher temperature, without secondary utilize directly by flue, smoke pipe discharged to outdoor, reduce the utilization rate of the energy, while also pollute environment.
Utility model content
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact conformation, effectively can improve heat utilization rate, reduce the off-gas recovery energy conserving system of the commercial gas-fired stove of pollutant emission.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of off-gas recovery energy conserving system of commercial gas-fired stove, comprise stove, the top of described stove is provided with the bowl of embedded shape, premixer is formed between the bottom of described bowl and stove, ignition module is provided with in described stove, afterheat energy-saving assembly and fume emission assembly, described ignition module is located in premixer, described ignition module comprises the big fire nozzle be located at bottom premixer, described big fire nozzle is positioned at the below of bowl, honeycomb type fire plate is provided with between described big fire nozzle and bowl, little fire-fighting mouth is provided with in described honeycomb type fire plate, be provided with in described stove little fire-fighting mouth match distribution igniter, described little fire-fighting mouth is connected with Gas Pipe respectively with big fire nozzle, described premixer is connected with air hose,
Described afterheat energy-saving assembly comprises and is located at ring smoke passage in stove and water-supply-pipe, described ring smoke passage is communicated with by flue gas circulation passage with between premixer, dish visible peristalsis visible intestinal peristalsis water pipe is provided with in described ring smoke passage, one end of described dish visible peristalsis visible intestinal peristalsis water pipe is connected with water-supply-pipe, and the other end of described dish visible peristalsis visible intestinal peristalsis water pipe is connected with water inlet pipe;
Described fume emission assembly comprises the chimney platform being located at stove upper one end, described chimney platform is provided with chimney, described chimney is communicated with by the upper end of smoke pipe with ring smoke passage, one end of described water-supply-pipe extends in chimney platform, and the outer end of described water-supply-pipe is provided with the tap distributed that to match with bowl.
As preferably, described air hose is located in ring smoke passage, and described air hose is dish visible peristalsis visible intestinal peristalsis, and the outer end of described air hose is connected with blower fan, is provided with smoke regulating valve between described chimney and smoke pipe.
As preferably, described ignition module is located at the interposition of ring smoke passage.
As preferably, in described Gas Pipe, water inlet pipe, be respectively equipped with control valve.
During work: combustion gas and air mixture are lighted after honeycomb type fire plate, become high temp fire cigarette to heat iron pan, flue gas enters the ring smoke passage of both sides, cold water feeding dish visible peristalsis visible intestinal peristalsis water pipe and high-temperature flue gas are carried out heat exchange by water inlet pipe, cooling flue gas after heat exchange enters chimney, cooling flue gas is discharged by chimney, and warm water is connected with tap by water-supply-pipe.Blower fan is by outdoor cold air feeding dish visible peristalsis visible intestinal peristalsis air hose, and high-temperature flue gas and outdoor cold air heat exchange, the cooling flue gas after heat exchange is discharged by chimney, and cold air passes into premixer and combustion gas mixing after absorbing heat energy.
Therefore, the off-gas recovery energy conserving system of commercial gas-fired stove of the present utility model, compact conformation, effectively utilizes waste heat, improves serviceability.
