As shown in Figure 1, the device of living beings second pyrolysis of the present utility model, comprises biomass catalyzing pyrolysis gasification device, biomass boiler.Charging aperture 3 drives raw material propeller that raw material is sent to combustion chamber by charging motor 4, and combustion chamber comprises dry section 6, reducing zone 7, oxidation reaction zone 8; Raw material carries out oxidation reaction in oxidation reaction zone 8, produces a large amount of first fuel gas; The lime-ash of raw material is discharged from the slag-drip opening 10 being driven by deslagging motor 11.Just fuel gas is reverse by the top in raw material district, and enters cloth headroom 13 at blow vent 5 and carry out gas distribution.Just fuel gas is evenly by the catalyst bed 14 of removable switching, generation catalytic reaction, and the cracking again of the sufficient gas of all tar and not cracking, has strengthened the calorific value of gas.Heat by gas and air supply mouth 15 mix and play oxidation reaction, radiate a large amount of heats here, by the mode evenly friction burning continuously of heat supply, the endothermic system efficiency of boiler improves rapidly, also increase the speed of gasification, improved the whole efficiency of boiler.By the water tank 16 of even friction burning heating boiler, make water tank 16 produce steam and enter into steamdrum 18 through water pipe 17.Gas after burning is mainly carbon dioxide and water, by the outer row of exhaust outlet 1 of boiler.At boiler exhaust mouth 1, band heat exchange cyclone dust collectors 2 have been installed, its effect is to make heat turn back to the cloth headroom 13 of air inlet, has strengthened the biomass catalyzing cracking reaction of raw material, thereby has improved the reaction of oxidation.Boiler chimney tail gas has reached the qualified requirement of environmental protection after getting rid of by such dedusting.Whole gasification of biomass, first fuel gas carry out uniform friction-type burning boiler, the tail gas of boiler chimney reclaims for biomass gasification reaction through dedusting, the rate of gasification of whole gasification improves, waste heat recovery, there is no the outer row of heat, the endothermic system efficiency of boiler has greatly improved, whole implementation process can realize the evenly fast fully effect of burning gases, and heat utilization efficiency is high, reaches the target of efficient, science, environmental protection.
Application Example 1
The efficiency of combustion of the device of living beings second pyrolysis of the present utility model is significantly promoted, without tar, and gas free from dust after burning, without carbon dioxide etc., Wuming County Pharma Inc. is used after 4 tons of boilers experiments, and fuel cost directly declines 30%; Without supporting any environmental protection equipment, facility, inorganic agent, environmental protection cost declines 100%; Automatic management, saves manpower; Comprehensively reduce costs more than 35%, boiler whole efficiency brings up to 93% from 75%, and boiler chimney is not seen and smoldered, and stack effluents index is significantly less than the standard that country limits! Can be rated as boiler that can not want chimney.
