One correspondence.
The present invention uses far-infrared thermal radiation pipe heat radiation drying technology, drying chamber to coordinate far-infrared thermal radiation pipe to drying
Indoor workpiece（Or article）Carry out drying waste heat to recycle, it is clear to carry out dust by cyclone separator to the gas of combustion gasification
Remove, operationally, biomass fuel is positioned in feed bin, and biomass fuel is delivered into gasification combustion engine by conveying auger
In vaporizer, rapid under anaerobic condition with the air entered from vaporizer bottom there is Pintsch process reaction, produce high temperature combustion
Gas.High-temperature fuel gas burn completely in combustion chamber, release hot gas, and combustion chamber gas out is by cyclone separator；Air inlet
In, far-infrared thermal radiation pipe is dried the object in drying chamber to drying chamber surrounding emitting heat quantity, meanwhile, recovery it is remaining
Heat is so burnt in machine vaporizer by circulating line, blower fan and blower fan wind pipe into gasification.
The present invention has the advantage that：
Last waste heat gas is carried out recovery re-using by the 1st, energy-conservation, this programme, and the thermal efficiency is high, and thermal losses is smaller.
2nd, drying piece surface surface temperature equilibrium everywhere in drying chamber, aluminium film reflected temperature thermal losses is small.
3rd, dedusting is carried out using cyclonic separation to the hot gas for entering far-infrared radiant tube, makes far infrared radiation inside pipe wall clear
It is clean, shorten the cleaning cycle of far-infrared radiant tube.
Brief description of the drawings
Fig. 1 is structure chart of the invention.
Specific embodiment
In conjunction with accompanying drawing, the present invention is described in detail.
Reference picture 1, far infrared recycling residual heat drying unit, including feed bin 1, combustor, drying chamber 2 and smoke evacuation
System, combustor is connected by the intake stack 41 with cyclone separator 3 with drying chamber 2, wherein, the bottom of cyclone separator 3
It is provided with an ash collecting box 31.Far-infrared thermal radiation pipe 21 is provided with drying chamber 2, drying chamber 2 is provided with drying chamber door 22, and drying chamber 2 leads to
Cross wind pipe 42 to be connected with smoke evacuation system, smoke evacuation system is connected by circulating line 43 with combustor, wherein, combustor is gas
Change combustor, including the combustion chamber 51 that sets gradually up and down and vaporizer 52, combustion chamber 51 is by crossover sub 61 and whirlwind point
