Common name such as agricultural crop straw, forestry waste, solid life refuse solid biomass also is called for short biomass.The conversion of current domestic and international biomass energy all is to be gasified raw material with the loose biomass pulverized, pyrolytic gasification in fixed bed or fluidized-bed gasification furnace.For avoiding vapourizing furnace slagging scorification, deslagging, must control gasification temperature, the fuel gases calorific value that is obtained is generally lower, can only make fuel and use.In addition, carbon content height in the lime-ash, the coal-tar middle oil content of combustion gas is also high, easy blocking pipe, the waste water that contains tar simultaneously also pollutes the environment.
Three, summary of the invention
Vapourizing furnace provided by the utility model, be intended to obtain high-grade gasified raw material, promptly both can do combustion gas, can be used as the raw material of synthesising biological fuel again, technical problem to be solved will improve the quality of gasification efficiency and combustion gas on the one hand, realizes operate continuously on the other hand under the prerequisite that guarantees the gasification ambient stable.
The technical solution of the utility model comprises pressure-bearing gasification body of heater, feeding device, slag discharging device etc., pressure-bearing gasification body of heater is that the biomass block energy transforms the place, so-called biomass block is meant biomass compression moulding after pulverizing, drying, fine and close briquetting can improve the temperature of pyrolytic gasification, to improve gasification efficiency.
Pressure-bearing gasification body of heater is the cavity 1 that has insulating 2, and charging (biomass block) device is arranged on it, under it slag discharging device is arranged.
In cavity 1, be provided with fire grate 3, the below of fire grate 3 is disposed with hybrid chamber 4, shock chamber 5 and cinder tank 6, each storehouse, chamber are isolated by push- pull valve 7c and 7d and are sealed, and just between shock chamber 5 and cinder tank 6 push-pull valve 7c are arranged, and push-pull valve 7d is arranged below cinder tank 6.Ignition dope gas import 8 is arranged on the hybrid chamber 4 and controlled by fluid valve 9, so-called ignition dope is meant oxygen or is rich in the air of oxygen, to improve the pyrolytic gasification temperature.Cinder tank 6 storage lime-ash, but just deslagging of push-pull valve 7d opened.Water pipe 10 can water filling in cinder tank 6 and shock chamber 5, water has cooling lime-ash and water seal effect, in addition, it mainly acts on is when the fused lime-ash falls into shock chamber 5, meet the water quenching, can generate a large amount of water vapour and enter cavity 1, reaction generates hydrogen under hot conditions, to improve the quality of combustion gas, can cool off fire grate 3 simultaneously.
Also be provided with fire hole 11 and at least two thermometer hole 12a, 12b and combustion gas fairlead 13 on cavity 1, as pressurized vessel, thermometer 14, tensimeter 15 and safety valve 16 also are provided with in the lump.The return line 17 that is parallel with on the combustion gas fairlead 13 by magnetic valve 18a control is connected on the fluid valve 9, its effect is when beginning to light a fire or other occurs and cause the combustion gas quality instability when unusual, can not supply with the user, under the suction function of fluid valve 9, make it to return cavity 1.
Be disposed with feed bin 19, bunker 20 and hopper 21 on cavity 1 top.Feed bin 19 is sealed by push-pull valve 7a, 7b, just between cavity 1 and feed bin 19 push-pull valve 7a is arranged, and between feed bin 19 and bunker 20 push-pull valve 7b is arranged; The return line 22 that feed bin 19 is provided with by magnetic valve 18b control is connected on the fluid valve 9, and its effect is to reclaim the combustion gas of speeding to put when valve 7a feeds in raw material when opening in cavity 1.
For keeping the stopping property of system, between bunker 20 and hopper 21, be provided with blocking valve 23.
For strengthening the intensity of feeding device and slag discharging device, water cooling chuck 24a is set on feed bin 19, hybrid chamber 4 and shock chamber 5 are provided with placed in-line water cooling chuck 24b.
Observe for convenient, hybrid chamber 4 is provided with observation, inspection port 25.Cinder tank 6 is provided with slag position window 26.
In feeding unit, belt feeder 27 can be set biomass block is sent in the hopper 21.
In drawing mechanism, spiral tapping machine 28 automatic removing dust slags can be set.
This pressure gasification stove is like this work, and lay ignition substance on fire grate 3 is opened fire hole 11 earlier, closes after lighting ignition substance.Open push-pull valve 7a and add biomass block.Open magnetic valve 18a and 18b and fluid valve 9 simultaneously, when closing push-pull valve 7a, close magnetic valve 18b.By oxygen or the oxygen-rich air that fluid valve 9 is introduced, improve cavity 1 interior oxidizing temperature on the one hand and reach 1400 ℃, make the cavity 1 interior formation pressure of sealing on the other hand, and control pressure 0.2～1.6MPa; The fused lime-ash falls into shock chamber 5 in oxidising process, generates water vapour and enters cavity 1, analyzes the composition of combustion gas, works as CO
2, CO, H
2Close magnetic valve 18a when ratio is suitable, combustion gas is delivered to the user by fairlead 13.Behind shock chamber's 5 long-pending full lime-ash, open push-pull valve 7c, allow lime-ash fall into cinder tank 6, close push-pull valve 7c, but open just deslagging of push-pull valve 7d.
