Description
Technical field
The utility model belongs to fuel gas hot-blast stove technical field, and in particular to a kind of energy-saving grain heat-drying gas hot-air
Furnace.
Background technique
Currently, the heat source source of grain heat-drying is substantially divided to two kinds, one is using coal as fuel, indirect type takes hot-air seasoning,
Energy waste is big, not environmentally, is now gradually eliminated.Another kind is using fuel gas as fuel, and cut-off connects hot-air seasoning, this baking
Dry (hot wind) furnace is structurally characterized in that flame after inner cylinder inboard is by furnace inner cylinder heat temperature raising, purges inner cylinder using external cooling wind
Afterwards, flow forward is mixed into wind mixed chamber with the flue gas after burning, and this structure can use direct hot wind, most of flame of burning
It is hidden in inner cylinder inboard, so that inner cylinder temperature is constantly in the condition of high temperature, because air inlet enter cooling wind cannot sufficiently take away in
Heat on barrel, makes inner cylinder be chronically at red heat state, and radiations heat energy is overflowed with air inlet or inhaled by furnace body frame and heat preservation
It receives, heat waste is very big.
Summary of the invention
The utility model provides a kind of energy-saving grain heat-drying fuel gas hot-blast stove aiming at the above problem.
In order to realize the above-mentioned purpose of the utility model, the utility model adopts the following technical solution, the utility model packet
Furnace body is included, furnace body one end is provided with gas burner, the combustion barrel of gas burner is provided in furnace body, it is characterised in that: furnace
Combustion barrel is provided with tangential air inlet on body, the combustion barrel end is provided with diffusing cone, diffusion poppet surface setting
There is tangential whirl hole；It is provided with gap between the diffusing cone and inboard wall of furnace body, furnace body end is provided with to be gone out with diffusing cone
The corresponding mixed air duct of mouth.
As a kind of preferred embodiment of the utility model, there are two tangential air inlets, one to inhale for the furnace body surface setting
Air port is set to one upper lateral part of furnace body, and another air inlet is set to the lower part of the furnace body other side.
As another preferred embodiment of the utility model, opening and closing damper is provided in the air inlet.
The utility model has the beneficial effects that flame is not disturbed by cooling air-drying on the inside of the combustion barrel of the utility model, burning is steady
Fixed sufficiently diffusing cone keeps flue gas circulation unobstructed, can be discharged in time, the residence time is short, makes the temperature of combustion barrel and diffusing cone significantly
It reduces, when eddy flow cooling wind washes away combustion barrel and diffusing cone, the radiations heat energy of combustion barrel is substantially zeroed, so outside furnace body not
Insulation is needed, to reach energy-efficient purpose.
The utility model hot-blast stove is reasonable, fully utilizes fuel, reduces thermal loss, and structure is simple, and occupied area is small,
Manufacturing cost is low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the side view of the utility model.
Fig. 3 is the A-A cross-sectional view of Fig. 1.
1 it is gas burner in attached drawing, 2 be furnace body, 3 be opening and closing damper, 4 be combustion barrel, 5 be air inlet, 6 is diffusion
Cone, 7 be whirl hole, 8 be mix air duct.
Specific embodiment
The utility model includes furnace body 2, and 2 one end of furnace body is provided with gas burner 1, is provided with fuel gas buring in furnace body 2
The combustion barrel 4 of device 1, it is characterised in that: combustion barrel 4 is provided with tangential air inlet 5,4 end of combustion barrel on furnace body 2
End is provided with diffusing cone 6, and 6 surface of diffusing cone is provided with tangential whirl hole 7；It is arranged between 2 inner wall of the diffusing cone 6 and furnace body
There is gap, 2 end of furnace body is provided with mixed air duct 8 corresponding with the outlet of diffusing cone 6.
As a kind of preferred embodiment of the utility model, 2 surface of furnace body setting is there are two tangential air inlet 5, and one
Air inlet 5 is set to 2 one upper lateral part of furnace body, and another air inlet 5 is set to the lower part of 2 other side of furnace body.
As another preferred embodiment of the utility model, opening and closing damper 3 is provided in the air inlet 5.
Specific workflow: gas burner 1 can be one-touch starting automatic control burner, provide for oneself combustion fan and
Valve group, 1 control cabinet power transmission of gas burner, before fuel gas is supplied to 1 valve group of gas burner, user starts air-introduced machine, closes
Air door is closed, air inducing fan delivery source is provided by air inlet 5, flows through furnace body 2 and wind mixed chamber.One-key start gas burner 1, flame
It establishes, after normal combustion, opens air inlet 5, the diameter of normal combustion and length can be after calculating really in combustion barrel 4 for flame
Fixed, the tail end of flame is extend into diffusing cone 6.Hot fume expands in diffusing cone 6, flows to mixed air duct 8, at this time fuel gas
Completely burned, heat release reach maximum, are cut in combustion barrel 4 in eddy flow state by the cold wind that air inlet 5 enters, flow to mixed wind
Cylinder 8, by diffusing cone 6 whirl hole 7 when, part cold wind tangentially enters inside diffusing cone 6, the cold wind stream entered by air inlet 5
Through arrive diffusing cone 6 tail portion when, not only cooled the surface of combustion barrel 4 and diffusing cone 6, but also make the hot cigarette of 6 internal edge of diffusing cone
Gas cooling, so combustion barrel 4 is low with the surface temperature of diffusing cone 6, thermal radiation loss is few, and eddy flow cold wind washes away in addition, furnace body 2
The temperature of outer surface is as the cold wind temperature of inspiration, so 2 outer surface of furnace body is not required to Insulation, all heat of fuel release
Amount flows into mixed air duct 8, converges with eddy flow cold wind, reaches preferable mixed effect, mixed low temperature at the necking through mixed air duct 8
Flue gas enters the wind mixed chamber of user, is siphoned away by air-introduced machine.
The process of blowing out is to press the stop key of gas burner 1, and all automatic valves close cutting gas source, combustion fan
It is purged and (is set by the control system of gas burner 1), when the air-introduced machine temperature of user drops to 80 DEG C or less, Quan Mianting
Machine.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Such as position and the air inlet of air inlet
The shape of angle or furnace body shell uses needs as long as meeting, is within the protection scope of the utility model.
