Abstract

Take gas -cooker of graphite heat exchanger is including establishing bowl, tray for combustion, mixing chamber, ejector, the gas pipe in the shell, gas valve, blast pipe, exhaust fan. The improvement done is the heat exchanger of compriseing the carbon tube of taking finned plate of punch holder and lower plate centre centre gripping below shell internal reflection cover. The hot flue gas that gas -cooker in use produced is followed under the effect of draught fan negative pressure and is returned to heat exchanger giving off heat under its outside of process of bowl upper end, and the combustion air who comes from the combustion air input tube rises behind heat exchanger internal absorption heat voluntarily, and the entering mixing chamber fires the mixed after combustion of tracheal combustible gas with coming from, so adopt backheat mode heating combustion air to improve the furnace temperature. The utility model discloses, make hot flue gas heat that the burning produced once more by the backheat utilization, can increasing the heat efficiency, reached energy saving and emission reduction's mesh to make the flue gas pass through exhaust fan and discharge, make the kitchen environment improve.

Described lower plate edge is upturned, and there is the hole be connected with combustion air input pipe centre, wears the hole of lead screw in addition and installs the hole of graphite-pipe to lower convexity.

Described split-wind plate comprises the circle up and down of fixing graphite-pipe, has the hole by heat smoke in two circles opposing upper and lower; Also have the hole by combustion air, and wear the hole of lead screw.

Described reflector upper end outer circumference be provided with projection its, be provided with the hole can passing mixing chamber (injector) in the middle of the end.

The injector sidewall having cyclic convex edge to be connected with mixing chamber outside described mixing chamber is jagged.

Described shell is tubular, there is outside Extravagant head the upper end of shell, sidewall is provided with and inserts the hole of Gas Pipe and the faulting of slab ends of mounting heat exchanger, is provided with collector box below at the bottom of shell, and box body is provided with the blast pipe that can be connected with box body in addition through the hole of combustion air input pipe.

General principle of the present utility model is: the heat smoke that the gas-cooker of band graphite heat exchanger in use produces returns under the effect of air-introduced machine negative pressure from reflector upper end is outside it, enter hole that train wheel bridge raises up by inside graphite-pipe, (holes through two relative split-wind plates of graphite-pipe) and lower plate are to the hole of lower convexity, collector box is come downwards to, through blast pipe by outside air exhauster discharge chamber after releasing heat; Combustion air from combustion air input pipe passes through the hole of wing plate and split-wind plate outside graphite-pipe in heat exchanger, automatically rise after absorbing heat, enter injector (mixing chamber) through the short tube on train wheel bridge and rise to tray for combustion burning after mixing from the fuel gas of Gas Pipe, so adopt backheat mode to heat combustion air and improve furnace temperature.

The beneficial effects of the utility model are that the heat smoke heat that burning can be made to produce is utilized by backheat again, preheating, by participating in the air of reaction, can improve the thermal efficiency, reach the object of energy-saving and emission-reduction, and flue gas is discharged by air exhauster, kitchen environment is improved.
