Description
Technical field
The utility model relates to living beings incineration technology field, particularly belongs to a kind of gasification burning phase-splitting stove for living beings.
Background technology
Biomass fuel and organic waste etc. are when combustion and pyrolysis, burn insufficient, often discharge a large amount of flue gas, in flue gas, pernicious gas is discharged in air simultaneously, causes serious injury to environment, and efficiency of combustion is general not high, for existing combustion furnace, also have requirement to the adaptability of fuel type, Load Regulation difficulty is large, ash comprehensive utilization rate variance.
Summary of the invention
Namely the purpose of this utility model is to provide a kind of gasification of biomass burning phase-splitting stove, to reach the object of sufficient combustion, decreasing pollution discharge.
Gasification of biomass burning phase-splitting stove provided by the utility model, its chamber structure comprises vaporizer and combustion chamber, it is characterized in that, combustion chamber is divided into the first reverse-running section, the second reverse-running section, the 3rd reverse-running section, and the direct of travel along flue gas is tortuous successively to be arranged; Be air distribution plate bottom described vaporizer, First air import, steam import be set below air distribution plate, air distribution plate arranges blast cap, box out in the middle of air distribution plate, connect slag-discharge pipe; The junction of vaporizer and combustion chamber first reverse-running section, is provided with fuel conveyor and secondary air inlet; Combustion chamber second reverse-running section and the 3rd lower end, reverse-running section junction are provided with the first dust leg; The 3rd described reverse-running section connects discharge section, and the end of discharge section arranges deduster, and deduster has the second dust leg, separately has heat smoke to export and is connected with outside air-introduced machine.
Good effect of the present utility model is mainly:
1, air distribution plate is entered by a high-pressure blast at vaporizer, then by blast cap evenly a small amount of oxygen supply, bottom fuel in vaporizer is burnt on a small quantity, large fuel Quick-gasifying under high temperature state generates imflammable gas, imflammable gas after gasification is entered the first reverse-running section of boiler furnace by drainage, makes gasification gas and the abundant mixed combustion of oxygen by dispensing Secondary Air.
2, the second reverse-running section of boiler furnace, the 3rd reverse-running section forms a U-shaped separator, both can make the biomass fuel of high-volatile abundant after-flame in stove, most of dust can be made again to be separated under gravity, is discharged by the first dust leg.
3, the coke waste heat in vaporizer after gasification also can meet the gasification heat that heating newly enters the biomass fuel in stove; And the gas that gasifies carries carbon residue granule and part coke tar particles completes premixed combustion in multiple backhaul, flame is long, and degree of filling is good, heat exchange is even, without tar deposition, efficiency of utilization is high, makes high low-grade fuel all can realize low temperature without tar gasification also efficient burning.
Accompanying drawing explanation
Accompanying drawing part discloses specific embodiment of the utility model, wherein,
Fig. 1 is the utility model cross-sectional view.
Detailed description of the invention
As shown in the figure, gasification of biomass burning phase-splitting stove provided by the utility model, its chamber structure comprises vaporizer 17 and combustion chamber.Combustion chamber is divided into the first reverse-running section 16, second reverse-running section 15, the 3rd reverse-running section 14, and the direct of travel along flue gas is tortuous successively to be arranged.The bottom of vaporizer is air distribution plate 3, arranges First air import 4 and steam import 5, air distribution plate is arranged blast cap 2 below air distribution plate, boxes out in the middle of air distribution plate, connects slag-discharge pipe 6.The junction of vaporizer and combustion chamber first reverse-running section, left side is provided with fuel conveyor 1, and right side arranges secondary air inlet 7.Combustion chamber second reverse-running section and the 3rd lower end, reverse-running section junction are provided with the first dust leg 8; The 3rd described reverse-running section connects discharge section, and the end of discharge section arranges deduster 11, and deduster has the second dust leg 9, separately has heat smoke to export 10 and is connected with outside air-introduced machine.
Vaporizer 17 top has necking down, i.e. the part that reduces of internal diameter, and the flammable macro particles fuel that the imflammable gas of vaporizer both can have been made to carry forms Inner eycle, also can accumulate heat, for fuel gasification provides condition.
Described discharge section inside is also provided with loop economizer 13 and tubular air preheater 12.
The utility model is in conjunction with Combustion technology of circulating fluidized, the combustion gas generated with gasification and flammable liquid carry out Thorough combustion by secondary oxygen supply, carbon dioxide reduction technique, pyrolytic gasification technology are combined simultaneously, fume emission problem when solving the pyrolysis such as biomass fuel and organic waste, have that efficiency of combustion is high, pernicious gas row trace discharge in fuel kind wide adaptability, flue gas, the advantage such as load regulation range is large, lime-ash can fully utilize.In addition, introduce boiler water steam and cook gasifying agent, water vapour carbon residue burning zone with process red charcoal and reduction reaction will occur, the fuel gas such as more hydrogen, methane can be generated, so namely, add generator yield, improve fuel gases calorific value, additionally reduce generation and the discharge of pollutant.
Gasification of biomass phase-splitting combustion type technology is without the need to the outer dust pelletizing system of stove, use internationally recognized clean energy resource fuel, burning brand-new in stove, gas solid separation and heat transfer mechanism, realize " in stove smoke elimination, dedusting ", it is made to discharge fume colourless, the trace discharge of flue dust, S02 and NOx.The utility model combines in a stove complementary control technology, gas-solid burning phase-splitting technology, gasification, burning is integrated in one, and achieves the continuous of fuel and clean combustion.
During the utility model load variations, only need fuel metering addition, air capacity, a point bed banking fire technology need not be adopted as other boilers.Also unlike pulverized-coal fired boiler, combustion-supporting with oil during underload, maintain smooth combustion.Load regulation rate can reach (3 ~ 4): 1.Load Regulation speed is very fast, generally can reach per minute 4%.More solve the chain-grate boiler thermal efficiency low, use biomass fuel, the fugitive constituent in flue gas and char particle can not form the air pollution problems inherent of black smoke by after-flame.
The utility model belongs to low-temperature burning, and after-flame condition excellent in stove can make in-furnace dust slag carbon content be zero completely, generates linen powder, belong to low temperature to grill thoroughly, be easy to the comprehensive utilization realizing lime-ash, as Crop fertilizer, make the construction materials such as cement.Low temperature grills thoroughly the extraction being also conducive to rare metal in lime-ash simultaneously.
