Abstract
A low pressure thermal cracking gasifier of internal combustion is a horizontal pressure vessel. Feeding and discharging mouths are in the two ends of the furnace body, making the biomass materials stay in the furnace long enough to fully react. A mixing propeller of axial direction propels the materials from feeding end to discharging end. The combination gas of combustion provides the temperature of 400 to 800 DEG C and the pressure of 0.5 to 4Kg/cm<2>, where temperature is controlled through adjusting the combination ratio of the gas and air compressor and pressure is controlled by the pressure adjustment valve. The materials, during inadequate combustion and gradually mixing, is continuously thermally cracked and carbonized to produce the gas phase of the tar and CO<2> and carbon, which catalytically cracks the tar to produce hydrogen compound, at the same time, deoxidizes the CO<2> to produce CO, the combustion gas is transmitted into storage tank from air outlet at last and slag is discharged from slag outlet. A plurality of energy transformation forms, such as thermal cracking, carbonization, catalytic cracking, and oxidation-reduction, are finished in the same pressure vessel, realizing the direct gasification of biomass with the energy transformation rate above 90 percen.
Description
One, technical field
The utility model relates to a kind of use device of biomass energy, exactly is a kind of solid biomass internal combustion type thermal cracking in low pressure gasification stove.
Two, background technology
Agricultural crop straw and forestry waste claim solid biomass usually.Direct gasification is a kind of main method that industrialized developing utilizes the solid biomass energy.Pyrolytic gasification and destructive gasifying are the main two kinds of technologies that adopt at present under the normal pressure.Pyrolytic gasification is vaporized chemical with the air, and obtaining with CO by redox reaction is the inflammable gas of main component, the common 4000～5000KJ/M of its calorific value
3With the hydrocarbon polymer is the inflammable gas of main component, and its calorific value is up to 12000～15000KJ/M
3The former finger secluding air of destructive distillation heating raw makes it the technological process that charing obtains volatile matter simultaneously, but uses the internal combustion type destructive distillation usually in the art, promptly at first makes the part material pyrolysis, utilizes the gasification heat release to heat all the other raw materials.Pyrolysis and destructive distillation also generate charcoal except that generating inflammable gas, this part charcoal can be converted into hydrocarbon polymer.As the disclosed combined bio matter of CN 2813616Y vapourizing furnace, pyrogenous origin splitting gas and charcoal are sent into the inflammable gas that generates hydrocarbon-containiproducts in the high temperature reaction stove by chemical reaction again in the vapourizing furnace.
Three, summary of the invention
The utility model is intended to a pressurized vessel solid biomass is converted into the inflammable gas of high heating value, and technical problem to be solved is to finish pyrolysis, destructive distillation, catalytic pyrolysis, redox homenergic switching process in an equipment.
The device that the utility model uses is a horizontal pressure vessel, claim internal combustion type thermal cracking in low pressure gasification stove (calling vapourizing furnace in the following text), comprise the band thermal insulation layer and be the body of heater of seat supports and feed inlet and outlet and necessary safety valve of pressurized vessel and relief valve etc., it is characterized in that opening for feed and slag-drip opening are positioned at the two ends of body of heater, make biomass material in body of heater, have enough residence times to make and react completely; Opening for feed and slag-drip opening use two-stage screw sealing feed appliance to guarantee the sealing of system respectively; Be provided with the axial advance device of band blade in the body of heater, in stirring, push the material of feed end to discharge end, use metal seal to guarantee the sealing of roller end; The required temperature and pressure of reaction in furnace is provided by the incendiary air mixture, by regulating combustion gas and compressed-air actuated ratio of mixture control temperature of combustion, by the pressure in the relief valve control stove; Air mixture can use injector tangentially to send in the stove from body of heater, also can use turbulent burner to send in the stove on the end socket of opening for feed one end.Injector, turbulent burner all should use with air compressor machine and pressure spot firearm combination accessory.For making full use of heat energy, on inboard wall of furnace body, scribble far ultrared paint and be provided with reflector.
Gasification is as follows, and pulverized biomass material adds from opening for feed, at first under the incomplete combustion condition by pyrolysis and destructive distillation, generate and to contain tar and CO
2, CO etc. gas phase and charcoal, the solid phase that contains charcoal continues by pyrolysis and destructive distillation in being stirred the process of passing, gas phase and charcoal constantly generate, simultaneously tar and the CO in charcoal and the gas phase
2Reaction, charcoal catalytic pyrolysis tar generates hydrocarbon polymer, with CO
2Be reduced to CO, last remaining lime-ash is discharged from slag-drip opening, and combustible gas is introduced gas-holder from the air outlet.This conversion process of energy needs certain temperature and pressure, 400～800 ℃ of temperature, pressure 0.5～4Kg/cm
2By controlling different temperature and pressures, the inflammable gas that obtains different hydrocarbons content (being the calorific value difference) is to adapt to different needs.The content of hydrocarbon polymer and temperature inverse correlation are with pressure positive correlation.
The utility model is by controlled temperature and pressure, in a pressurized vessel, finish multiple energy transformation forms such as pyrolysis, destructive distillation, redox, catalytic pyrolysis, realize the biomass direct gasification, and move, generate incessantly the higher and adjustable inflammable gas of calorific value continuously, simplified the technical process and the equipment of gasification greatly, energy transformation efficiency is up to more than 90%.
Four, description of drawings
Accompanying drawing is depicted as the structural representation of this vapourizing furnace.
Five, embodiment
As shown in drawings.This vapourizing furnace comprises that the inflammable gas band thermal insulation layer and that be the horizontal cylindrical furnace body 3 of seat supports and thermometer socket 14, safety valve 15, the tensimeter 16 of being with relief valve and band reducing valve 11 exports, and opening for feed 19 and slag-drip opening 20 are positioned at the two ends of body of heater 3; Connect two-stage screw sealing feed appliance 2 between opening for feed 19 and the hopper 1; Slag-drip opening 20 is connected and is isolated by air locking device 9 with two-stage screw sealing feed appliance 10; Rotating shaft 5 is arranged in body of heater 3, and there is metal seal 4 end, and frame agitating vane 6 is arranged in the rotating shaft 5; Inboard wall of furnace body scribbles far-infrared radiation coating 12 and reflector 13 is set.To be arranged on the body of heater of opening for feed 19 1 ends after shaped element injector 17 and 7 assemblings of pressure spot firearm, injector 17 also is connected with gas line 18 with air compressor machine 8 outlets respectively, and the air mixture of formation is tangentially sent in the stove after being lighted by pressure spot firearm 7.
Concrete operations are as follows:
Start stirring thruster and pressure spot firearm lights air mixture preheating body of heater to 400 ℃ and keeps 1Kg/cm
2Pressure adds the biomass material that is crushed to 1～2cm size from opening for feed then, because of oxygen supply deficiency in the stove, forms incomplete combustion, and raw material is by continuous pyrolysis and destructive distillation, and generation contains tar and CO
