Abstract
The utility model belongs to the technical field of heat supply, particularly a high-efficient energy-saving hot-air stove, comprising a heat exchange body, a burning chamber, a grate, a skirt support, etc. The utility model is characterized in that the heat exchange body is composed of six concentric cylinders with different diameters, and the spaces between the cylinders are air flow path chambers. Two of the flow path chambers are gas flow path chambers which are communicated with each other, and three of the flow path chambers are hot air flow path chambers which are communicated with each other. The bottom of the heat exchange body is provided with an ash hole. The utility model has the advantages of reasonable structure, long heat exchange flow passage of working medium and high thermal efficiency. The utility model is a heat supply device used in the food industry, the light spinning industry, the construction industry, etc.
Description
The utility model belongs to the heat supply process field, particularly relates to a kind of energy efficient hot air furnace.
In background technology, vertical hot furnace mainly is made up of body of heater, heat exchange body, combustion chamber and skirt etc., because the exhaust gases passes in the heat exchange body is shorter, the heat absorption runner of working medium is also shorter, and the dead angle is many in the flue gas process of circulation, and flue dust is got rid of also inconvenient, therefore, its thermal efficiency is lower, has also influenced service life and security simultaneously.
The purpose of this utility model is to provide a kind of hot working fluid exchange runner length, working medium, flue gas flow direction is reasonable, the thermal efficiency is high, soot emissions are easy to energy efficient hot air furnace.
The purpose of this utility model is achieved in that it comprises heat exchange body, combustion chamber, fire grate and skirt, outer cylinder in the heat exchange body is a body of heater, be provided with fire door and air inlet in the bottom of body of heater, be respectively equipped with heat outlet and exhanst gas outlet on the top of heat exchange body, it is characterized in that the heat exchange body is made up of six different concentric drums of diameter, space between the cylinder is gas flow process chamber, wherein two is the flue gas flow chamber that communicates, three is the hot gas flow process chamber that communicates, and is provided with ash hole in the bottom of heat exchange body.
Owing to be provided with two flue gas flow chambeies that communicate and three hot gas flow process chambeies that communicate on the heat exchange body of the present utility model, thereby its thermal efficiency ratio is higher, because of being provided with the heatproof sealing device at the heat outlet place, thereby the adverse effect that can avoid the metallic plate thermal expansion to be caused, in addition, after the bottom of heat exchange body is provided with ash hole, can remove flue dust easily.
In conjunction with the accompanying drawings and embodiments, the utility model is specified as follows:
Fig. 1 is a structural representation of the present utility model.
In Fig. 1, the utility model is mainly by the heat exchange body, combustion chamber 23, compositions such as fire grate 22 and skirt 21, the heat exchange body is by six different concentric drums 3 of diameter, 4,5,6,7,8 constitute, at cylinder 4, between 5 and cylinder 6, be respectively equipped with air duct 9 between 7,16, at cylinder 7, be provided with exhaust gases passes 10 between 8, outer cylinder 3 in the heat exchange body is a body of heater, be provided with fire door 2 and air inlet 18 in its underpart, also be provided with liner 17 in the heat exchange body, its below is a fire grate 22, be separately installed with heat outlet 12 and exhanst gas outlet 13 on the top of heat exchange body, the outside of heat outlet 12 is equipped with the sealing device 11 of heatproof, and sealing device 11 is connected cylinder 3 with the trapezoidal top of cylinder 4,4, cylinder 5,6, cylinder 7, three cavitys that constitute between 8 are the hot gas flow process chamber that communicates.Cavity between cylinder 4,5, the cylinder 6,7 is the cigarette flue gas flow chamber that communicates, in hot gas flow process chamber and flue gas flow chamber, be equipped with deflector 14 and strengthen fin 15, the bottom end seal of cylinder 5,6 is joined, and is provided with ash hole 19 below its bottom, so that remove the flue dust of sedimentation.During use, fuel is rendered to burning on the fire grate 22 through fire door 2, high-temperature flue gas in the combustion chamber 23 enters the flue gas flow chamber by exhaust gases passes mouth 10, thereby the barrel temperature of cylinder 4,5,6,7 is raise, the air themperature of barrel opposite side is raise, flue gas is discharged from exhanst gas outlet 13 at last, the flue dust of institute's sedimentation can be removed from ash hole 19 in the flow of flue gas process, the hot gas flow process chamber of stove outer air in air inlet 18 enters the heat exchange body, after absorbing the heat of barrel, from heat outlet 12 to extraneous heat supply.
