Below describe operation principle of the present utility model and design feature in detail
One, the solution (employing anticorrosion aluminium) of fuel tolerance problem.
Combustion chamber of the present utility model is cylinder barrel shaped, is formed by double-deck heat-and corrosion-resistant Welded, and interlayer is water tank.Water tank interlayer ensures that inboard wall of burner hearth is in relatively reasonable temperature range; avoid inwall Yin Gaowen and lower its service life; on the other hand, the vigorous combustion of combustion chamber completes the first time heat exchange of hot water generator by interlayer water tank, and plays insulation and protection two aspect effects.Aluminium alloy 6010 material has good corrosion resistance.Easily be oxidized in atmosphere, form a kind of transparent aluminum oxide film.Define the oxide-film of one deck densification in aluminum alloy surface, prevent the corrosion of alkalescence, widened the scope that can use fuel.
Two, the solution (cyclone firing technology) of coking problem in combustion chamber
The utility model adopts the chamber structure based on cyclone firing technology, biomass molding fuel is due to the complexity of composition own, its combustion process is also very complicated, mainly be divided into five burner intervals: (1) heat accumulation and drying stage, when temperature reaches 100 degree, biomass fuel enters drying stage, and moisture starts evaporation.(2) fugitive constituent is separated out and charcoal formation stages, i.e. destructive distillation stage, and when the raw material continuous heating of drying, fugitive constituent starts to separate out, and after volatilization, finally remaining is exactly charcoal.(3) fugitive constituent combustion phases, the fugitive constituent that biomass fuel high temperature pyrolysis is separated out at high temperature takes fire, and meanwhile, discharges a large amount of heat.(4) fixed carbon combustion phases, (5) residue ash content.Therefore, in combustion chamber, be provided with the tornadotron 40 of perforate, for combustion chamber provides the tangential wind-force of 6M/S.Living beings complete the combustion process in 1-4 interval in combustion chamber.When normal combustion state, because tangential force revolves wind action, form double-paraboloid wire shaped fire body state.Bottom is charcoal burning, and top is fugitive constituent vigorous combustion.Owing to adopting cyclone technology, combustion chamber endogenous substance high temperature, sufficient oxygen, fully disturbance and mixed, comparatively long residence time be satisfied simultaneously, the imflammable gas produced after fuel gasification reaches and burns completely before leaving burner hearth, can not Yin Wendu low, anoxic, disturbance undercompounding and produce the phenomenon that Pintsch process is carbon black.
Three, integrated form (combustion chamber+water tank, smoke pipe+water tank) heat exchange and the omnidistance exchange heat structure of burning
The utility model have employed integrated (combustion chamber+water tank, smoke pipe+water tank) heat exchange structure, material of main part aluminium alloy 6010 material, corrosion-resistant and heat conduction is fast.Water tank and combustion chamber, water tank and tube side burning smoke pipe integrate, and adopt dividing wall type exchange heat form, have both ensured that the heat conduction of pipe outer wall was direct, ensure that again tube wall is constant in certain temperature range.
Four, the solution of flying dust phenomenon and three groups of deadweight dedustings and water curtain dedustings.
The utility model have employed the process layout of omnidistance exchange heat of burning.The burning of combustion chamber, tube side smoke pipe inside all adopts vertical structure to design.In combustion chambers burn process, larger tiny living beings adopt cyclone firing, sufficient combustion, and the flying dust of residue some, due to the effect of deadweight, in the half-turn of six grades of tube side smoke pipe gas reversal chambers (deashing storehouse), realizes dedusting.Flying dust is made substantially to rest on deashing storehouse.Meanwhile, at stopping combustion phases, controller (in figure not display) is provided with soot blowing technique, ensure that in the shutdown stage, and in combustion chamber and six grades of smoke pipes, dust is cleaned.Screen collector is arranged on smoke suction machine backmost.Because contain moisture through the air of screen collector purification, can produce corrosion to inner-walls of duct below, smooth like this purifying air by water curtain, can directly be discharged in air, can not result in blockage to smoke suction machine and destroy.This screen collector also possesses higher efficiency of dust collection, and efficiency of dust collection can reach more than 99%.
All arrange water tank from combustion chamber to six grades of tube sides, the utility model top is provided with waste-heated water-tank, heat exchange area reaches maximum, makes exchange heat more abundant simultaneously.
Five, dividing wall type adverse current low thermal resistance technological design
The utility model adopts dividing wall type exchange heat mode, and the utility model enters cold water the 6th grade of tube side (flue-gas temperature is minimum), goes out hot water at first order tube side (flue-gas temperature is the highest).In heat exchanger, the relative current of fluid is to being counter-flow designs.When considering adverse current, along the temperature difference distribution uniform of heating surface aqueous medium and flue gas.Under the condition that the out temperature of cold and hot fluid is certain, the mean temperature difference of adverse current is maximum.Assuming that heat transfer area is constant, adopts during adverse current and the consumption of heating or cooling fluid can be made to reduce.Therefore, the utility model adopts counter-current process design to ensure that heat exchange process condition reaches optimum state.
The utility model unique distinction is combustion chamber, the burning of tube side smoke pipe inside all adopts vertical stratification to design, and fluid is that vertical water assures design, and this is a kind of design can lowering thermal resistance.Be different from the structure that the horizontal smoke tube of current domestic employing or fire are assured.
Owing to being all designed with deashing storehouse bottom six grades of tube side smoke pipes, at stopping combustion phases, controller is provided with soot blowing technique, ensure that in the shutdown stage, and in combustion chamber and six grades of smoke pipes, dust is cleaned.Effective cleaning, make smoke pipe inwall be difficult to form schmutzband, the thermal resistance of metallic walls is relatively little.In addition, in order to eliminate the thermal resistance of the thin layer of fluid of partition both sides viscous on heat-transfer area (being called boundary layer), the utility model is designed with booster pump (in figure not display) and smoke suction machine, improves flow velocity and the perturbation of fluid, thinning boundary layer, reduces thermal resistance and improves heat transfer coefficient.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
