Specific embodiment
A kind of barrel-shaped narrow slit whirlwind walks around to heat exchange air stove，Including stove seat 20 and body of heater 10，Body of heater 10 is above stove seat 20，Described body of heater 10 is hollow circular cylinder，It is sequentially provided with burner hearth 11 from the inside to the outside in body of heater 10、Flue gas walks around to chamber 6，Body of heater 10 shell and flue gas walk around to narrow slit between chamber 6 and form the first Heat Room 4，Flue gas walks around to gap between chamber 6 and burner hearth 11 and forms the second Heat Room 5，Described stove seat 20 is C-shaped，It is provided with flue 17 in stove seat 20，It is provided with exhaust opening 1 in the middle part of flue 17，Between stove seat 20 shell and flue 17, cavity forms preheating chamber 16，Preheating chamber 16 one end is provided with air inlet 18，Stove seat 20 top surface is along the circumferential direction uniformly provided with multiple interior side openings and outer openings，Preheating chamber 16 is connected by outer openings with the first Heat Room 4，Flue 17 and flue gas are walked around to chamber 6 and connect by interior side opening.
By this structure, walk around to heat transfer technology using three times, flow in making air by the narrow slit being formed between layers in multiple structure body of heater, reduce air-flow thickness, increase heat exchange area, extend transfer path, improve heat exchange efficiency；The flue design mutually isolated with hot-flow flue, it is to avoid smoke contamination hot blast, provides cleaning thermal source for drying operation.
Described body of heater 10 bottom side is provided with fuel inlet 13, opposite side is provided with hot-blast outlet 2, and fuel inlet 13 is communicated with burner hearth 11 bottom, and the second Heat Room 5 bottom is communicated with hot-blast outlet 2, it is provided with furnace wall 12, body of heater 10 bottom is provided with fire grate 15 at burner hearth 11 lower section fuel combustion.
It is provided with the screen cover 9 of multilayer porous structure, particularly in the second described Heat Room 5.The design of porous screen fan housing 9, allows focused airflow pass through aperture to become tiny air-flow and is uniformly distributed in Heat Room, reduce wind speed, extend heat-exchange time, improve hot blast temperature and heat exchange efficiency.
Described burner hearth 11 is hollow circular cylinder, and its top is along the circumferential direction evenly arranged with multiple flue gases and walks around to passage 8, and flue gas walks around to passage 8 and walks around to chamber 6 with flue gas and connects.The flue gas of independent design walks around to chamber 6 and flue gas is walked around to passage 8 and so that flue is isolated with hot-flow flue, it is to avoid hot blast is by smoke pollution.
Described the first Heat Room 4 bottom is along the circumferential direction provided with multiple hot blast guiding flights 3.
Described flue gas walks around to chamber 6 top and is along the circumferential direction provided with multiple flue gas guiding flights 7.
The design of guiding flight allows air-flow helically to move in annular passage, makes heat-transfer surface thermally equivalent, extends transfer path, improves heat exchange efficiency；
It is provided with fire door 19 at described fuel inlet 13.
Described stove seat 20 is provided with ash discharging hole 14, and ash discharging hole 14 is located at the C-shaped indentation, there of stove seat 20.
Described furnace wall 12 adopts refractory material.
The work process of the present invention is as follows：
First firewood or coal are added from fuel inlet 13, mix with the combustion air of 15 times entrance of fire grate, burn in burner hearth 11, flame and high-temperature flue gas walk around to passage 8 entrance flue gas by the flue gas that burner hearth 11 top is along the circumferential direction distributed and walk around to chamber 6, flue gas helically moves downward along annular chamber in the presence of flue gas guides flight 7, and uniformly heating flue gas walks around to cavity wall；After tail gas after heating enters flue 17 and heating preheating chamber 16 in stove seat through the peripherally disposed interior side opening of stove seat 20 top surface, extracted out by negative-pressure air fan through exhaust opening 1, to make full use of heat energy, improve the thermal efficiency.The big I of blower negative pressure by the solar term valve regulation being connected with blower fan, to adjust firepower size and hot blast temperature.
Subsequently, clean cold air, under malleation fan action, is pressed into stove seat preheating chamber 16 by air inlet 18, carries out first time heat exchange with the tail gas after burning through flue 17 outer wall；Air after preheating enters the first Heat Room 4 in body of heater 10 through the outer openings that stove seat 20 top surface is along the circumferential direction uniformly arranged, hot-air helically moves upwards along annular chamber in the presence of hot blast guides flight 3, uniform pickup flue gas walks around to the heat energy of chamber 6 outer wall, completes second heat exchange.Due to cold wind action, stove seat 20 and body of heater 10 skin temperature are unlikely to too high, both decrease heat-energy losses, and in turn ensure that and use safety.
Hot blast after second heat exchange enters the interlayer of screen cover 9 through furnace roof, uniform aperture through on screen cover 9 enters the second Heat Room 5, allow focused airflow become tiny air-flow to be uniformly distributed, reduce wind speed, extend heat-exchange time, inswept burner hearth 11 outer wall and flue gas walk around to chamber 6 inwall heat-transfer surface, complete third time heat exchange.
High temperature cleaning hot blast after three heat exchange is discharged by hot-blast outlet 2, sends into the heating equipments such as bakery, baking oven through hot air duct.By the temperature sensor on hot-blast outlet, hot blast temperature is monitored, is required with the stoving process adapting to different product.
