When the present invention uses, the 1 interior load garbage refuse from charging aperture 16 toward body of heater, pile with the back sealing, light the combustible of body of heater 1 bottom periphery then at slag notch 34, after combustible is lighted, under the draft effect of air-introduced machine 80, air is after body of heater 1 bottom heating, through a blast pipe 6, enter second-time burning fire tube 12 again, participate in burning with higher speed, make moisture content many, the calorific value height, the junk of complicated component, get angry rapidly, and flow, at this moment along the draft direction of second-time burning fire tube 12, it mainly is the junk around the burning filtering holes 30, intake by a wind of electrically operated valve 15 automatic controls makes the speed and the scope of junk burning controlled, thereby prolongs burning time and formation anoxic reducing environment.
Junk produces a large amount of gases when burning, enter second-time burning fire tube 12 through filtering holes 30, burning produces high temperature to radiation all around, burner hearth 37 junks are heated up rapidly, since in the burner hearth 37 many, the thickness of the junk capacity of dress greatly, highly high, adding has heat-insulation layer 4 insulations adiabatic in the furnace wall 9 of burner hearth 37, simultaneously, all electrically operated valves are closed, at this moment, burner hearth 37 is sealed isolated, so rubbish has adequate time evaporation, drying, destructive distillation, pyrolysis in whole burner hearth scope.Along with calory burning transmits continuously, radiation, make many, the organic many rubbish of water content under the reducing environment of high temperature anoxic, overflow gradually steam, fugitive constituent, and then the destructive distillation thermal decomposition takes place, produce a large amount of air mixtures of forming by fuel gas, steam, tar, flue gas etc.This process is constantly carried out, until rubbish finally become by destructive distillation carbon residue and collapse downwards fall electronic feeding-distribution device 28 after, new rubbish replenishes into again continuously.
In the combustion process of rubbish, open electrically operated valve 14, at this moment, the auxiliary air that is evenly distributed and the steam that replenish from secondary wind inleting tube 7 react as gasifying agent and red-hot carbon residue, keep and the combustion gasification process of stable rubbish.A large amount of air mixtures that burner hearth 37 produces, under the draft effect of air-introduced machine 80, enter second-time burning fire tube 12, mix with the tertiary air that enters from three blast pipes 8, in second-time burning fire tube 12 internal combustion, the air of limiting the quantity of of having realized the steam, carbon dioxide in the burner hearth 37 and having come in from secondary wind inleting tube 7 etc. are as the red-hot carbon of gasifying agent and burning, abundant generation such as the carbon residue of fast after-flame, the tar of suspension reduction wherein steam is reduced into carbon monoxide and hydrogen, carbon dioxide is reduced into carbon monoxide, and tar is broken down into hydrocarbon etc.In addition, the tar in the air mixture and suspension carbon granules etc. also significantly reduces because of reduction reaction, has not only purified combustion gas, and has avoided particulate polymerizations such as these tar, heavy metal steam, flue dust, and stops up, corrodes upstream device and pipeline.
When air mixture abundant burning in second-time burning fire tube 12 produces high-temperature flue gas, high-temperature flue gas is more than 1000 ℃, high-temperature flue gas is under the effect of second-time burning fire tube 12, make the above-mentioned tar completely of not eradicating once more, the heavy metal steam, flue dust, particulates such as dioxin wipe out to be burnt, in addition, because second-time burning fire tube 12 is very long, and second-time burning fire tube 12 shells are welded with fin 11, when stopping for a long time around the junk second-time burning fire tube 12, the heat of high temperature that makes full use of second-time burning fire tube 12 makes the most of organic matter in the rubbish around the second-time burning fire tube, become fuel gas and carbon granules by pyrolysis, fuel gas becomes fuel resource after condensation.And carbon granules continues to fall to gasification in the body of heater 1, owing in the burner hearth 37 electronic feeding-distribution device 28 is housed, when these by the rubbish residue of destructive distillation, pyrolysis, when falling into burner hearth 37 bottoms, by electronic feeding-distribution device 28 stirrings, loose, upset, mix formation turbulent flow accelerated combustion gasification with the air of limiting the quantity of, prevented these rubbish residue cokings knot cakes, influence whole gasification, and combustion.The effect of motor 35 in the electronic feeding-distribution device 28, electronic feeding-distribution device 28 can realize just changeing the counter-rotating effect, therefore just commentaries on classics, the counter-rotating by electronic feeding-distribution device 28, can separate slag, carbon residue, rubbish, unburnt high temperature carbon residue continues to stay electronic feeding-distribution device 28 tops and participates in the gasification reduction reaction, produces more fuel gas; Simultaneously, the slag of after-flame falls down, and ejects by slag notch 34.
The cone-shaped bulk cargo sheet 24 of wherein electronic feeding-distribution device 28 mainly is for junk being stirred, the junk utilization rate being improved.
After high-temperature gas enters spiral smoke box 22, after through spiral smoke box 22, to make the tar in the mist obtain separating, flow out from the hole of ring pipe 21, tar is flowed out from the tar outlet 20 that is arranged on spiral smoke box 22 bottoms, tar enters the high temperature carbon residue district of body of heater 1 bottom by tar efferent duct 73, and tar generation Pintsch process and catalytic pyrolysis change fuel gas into and participate in burning.
After high-temperature flue gas enters spiral smoke box 22, the junk of sending into from charging aperture 16 is preheated drying soon, simultaneously, since the second-time burning fire tube 12 in the body of heater 1 very long with and go up the fin 11 of welding, therefore make junk preheating, drying, destructive distillation pyrolysis abundant more, the fuel gas of a large amount of hydrocarbon-containiproducts of generation is many more.Therefore little to the water content restriction of junk, as long as the organic flammable composition in the rubbish can be kept burning, promptly enter body of heater 1 and carry out gasification process.Be accompanied by a large amount of generations of air mixture and constantly burning, furnace temperature will improve constantly, and the inlet by associated electrical movable valve control air at this moment temperature control within the required range, is kept and stablized required gasification temperature and thermal balance gets final product.
When needs go out combustion gas, open electrically operated valve 41, close electrically operated valve 42, can go out combustion gas by gas port 17, combustion gas enters condenser 44 by combustion gas efferent duct 43, again by water inlet pipe 45, outlet pipe 46, under the water circulating condensing effect that cooling chamber 48 forms, fuel gas is cooled, condensable composition in the fuel gas is condensed into thick fuel oil, with entering gs-oil separator 51 by combustion gas efferent duct 49 by the condensation composition, thick fuel oil and combustion gas that condensation is got off are separated, and thick fuel oil flows into oil storage 62 by fuel outlet 52, can further refine into product oil, obtain to utilize, can not store by combustion gas air exhauster 55 suction gas holders 60 by the condensation composition, also can extract purification out and make the finished product combustion gas, obtain recycling by gas outlet 61.When refuse thermal value in the stove is low, open combustion gas electrically operated valve 64, the fuel gas in the gs-oil separator 51 is advanced boiler tube 63 by combustion gas get back in the body of heater 1, as auxiliary fuel, with the maintaining heat balance.
In like manner, when needs go out flue gas, open electrically operated valve 42, close electrically operated valve 41, can go out flue gas by flue gas mouth 18, high-temperature flue gas (about 800 ℃) enters smoke eliminator 75, at spray quencher 76,1 second with the prompt drop to 100 ℃ of having to go to the toilet below, thereby avoided the generation once more of dioxin, toxic compositions such as the dust in removing smoke simultaneously, tar, hydrogen chloride, sulfide.Further purify trace harmful gases in flue gas by milk of lime circulatory pool 102 by middle spray thrower 77, thin spray thrower 78 through the cooling flue gas after being purified, realize non-pollution discharge, flue gas after being purified is introduced chimney 84 dischargings by flue gas baffle-box 79 by air-introduced machine 80, or directly enters chimney 84 dischargings by bypass pipe 82.
