21 are connected, and are fixed by bearing pressure and shaft coupling plate 15, it is ensured that power is inputted.
The outerplanar of envelope gas hood 19 after installing highly necessarily be greater than the water inlet plane of envelope compression ring type tank 20
100mm, it is ensured that the operating space that envelope gas hood 19 is installed, while sealing the inner surface of compression ring type tank 20 and to outside mandrel bearing fixed cover
The spacing on surface is 22mm, to ensure the operating space installed.
The internal diameter 824mm, external diameter 1436mm of the envelope compression ring type tank 20.Seal compression ring type tank inner surface and envelope gas hood 19
The spacing of outer surface is not less than 300mm, just the rotating operation in the middle of the envelope tank of compression ring type tank 20.Seal compression ring type tank water
Depth is not less than depth in 1.2m, the water of the envelope insertion envelope compression ring type of gas hood 19 tank 20 and is not less than 800mm, and so outside air leads to
Cross water segregation and cannot be introduced into pyrolytic reaction intracavitary, pyrolytic reaction intracavitary pyrolytic reaction gas can not be to outward leakage by water segregation..
Envelope gas hood 19 rotates in water, prevents extraneous air from entering, pyrolytic reaction gas can not be discharged, so as to reach cone
The sealing effectiveness of type blending auger 26.
Auger gasification power motor Β 1-1 are used as power using variable-frequency motor, adjust the tapered rotating speed of blending auger 26
Speed, just can control pyrolysis biological flue gas calorific value quality.
There is rubbish reductive cleavage to condense the pyrolytic gasification chamber of depickling mechanism, leaching under reference picture 4, tapered blending auger 26
Pipe 30, collection grieshoch 31, spiral transferring ash hoist 33, deposit ash pipe 34, envelope air water pond 35.Pyrolytic gasification chamber has middle temperature pyrolytic layer 28, height
Warm reductive cleavage layer 29.The lower end of spiral transferring ash hoist 33 is sunk in envelope air water pond 35.
Collect grieshoch 31 successively in heat-exchange tube 38, combustion gas transfer tube 39, combustion gas and surge pipe 40, inserted in combustion gas with surge pipe
Enter in combustion gas and surge tower 42 in neutralization caustic liquor in, in combustion gas and surge tower has combustion gas delivery outlet 41, neutralize caustic liquor import 43,
Stove internal pressure-regulating outlet pipe 45.
Spiral transferring ash hoist 33 is supported by spiral transferring ash discharge machine support 36, and heat-exchange tube 38 is supported by support post 32,:Combustion
Having on gas transfer tube 39 has water pressure gauge 46 on safety anti-explosive pipe 37, stove internal pressure-regulating outlet pipe 45, and by stove internal pressure-regulating outlet pipe branch
Frame 44 is supported.
During present invention work, house refuse is entered in compression screw shell 10 by tearing up garbage inlet 7, compresses feeding
Power motor Α 1 drives compression feeding screw axle 4 to rotate, and rubbish and compression screw shell are torn up from what charging aperture entered
10 produce extruding force, and the house refuse in compression screw spiral trough is extruded air and water, the air of extrusion under extruding force
It is discharged with water by exhaust outlet mouthful 9；And solid life refuse is got into contraction under the promotion of compression screw spiral and blocked
Sleeve pipe 11, the helicla flute of pyrolytic reaction chamber conical spiral 26 is got into through shrinking after the contraction mouth blocked in the middle of sleeve pipe shrinks
In.
Power is passed to upper power input shaft 13, upper power input shaft 13 by tapered auger gasification power motor Β 1-1
By power be transmitted to envelope gas hood 19, envelope gas hood 19 by seal gas hood gusset piece 14 by power be transmitted to bearing pressure and shaft coupling plate 15, bearing
Power is transmitted to same core power by the terraced axle 21 of same core power biography and passes terraced axle gusset piece 22 by pressure and shaft coupling plate 15, is finally passed to tapered
Blending auger 26, makes the tapered rotary work of blending auger 26, while the envelope gas hood 19 in envelope compression ring type tank 20 is in water
Middle rotation, tears up rubbish.
Electrical heating is first passed through to penetrate the high temperature that the temperature of high temperature reduction cleaving layer 29 rises to 1200 DEG C, 1200 DEG C to width up and down
Decay reduction successively, when upward width is mapped to middle temperature pyrolytic layer 28, temperature damping is to 700 DEG C.
The rubbish torn up through tapered blending auger 26, into middle temperature pyrolytic layer 28, in oxygen-free environment, in 700 DEG C of temperature
H is pyrolyzed under degree2、O、CO、CO2、H2The trickle material of a grain such as O, alkane, tar, charcoal.It is swollen that water in rubbish is heated evaporation Peng
Air pressure in the high temperature reduction cleaving layer all closed is set to increase to 3Kg hydraulic pressure values.
It is rotated down in tapered blending auger 26 under the promotion of spiral force, the trickle material of a grain goes downwards to high temperature reduction and split
Layer 29 is solved, under 3Kg hydraulic pressure values, 1200 DEG C of hot environments, the cracking reaction of tar was completed within 0.8 second time into H2, CO, first
Alkane etc. can not coagulate combustion gas, be pyrolyzed the carbon produced and occur reduction reaction generation combustible gas CO with carbon dioxide, therefore without carbon dioxide row
The problem of putting.
Reduction reaction generation H occurs for remaining carbon and the high-temperature vapour of water evaporation in envelope air water pond 352, CO can not coagulate combustion
Gas, completely eliminates carbon.Combustion gas can not be coagulated dust in combustion gas is filtered out through leaching pipe 30, cooled into heat-exchange tube 38, handed over
The hot water swapped out is used and outer confession for company, and the combustion gas after cooling in combustion gas with surge pipe 40 through inserting in combustion gas and surge tower 42
The acidic materials sloughed in caustic liquor in combustion gas are neutralized, the biological flue gas totally cleaned disappears through the output of combustion gas delivery outlet 41 into market
Sell.
Filter the dust in combustion gas to fall within collection grieshoch 31 and deposit in ash pipe 34, fall into the helicla flute of spiral transferring ash hoist 33,
It is output that to do building materials non-burning brick under water-stop.
If the atmospheric pressure in high temperature reduction cleaving layer is not enough, the height of adjustment pressure regulation outlet pipe 45, with regard to combustion gas can be improved
The depth that surge pipe 40 absorbs water mouth is neutralized, pyrolytic reaction intracavitary steam pressure is increased with this, until what is shown more than water pressure gauge 46
3Kg low pressure parameter values.High temperature reduction cleaving layer is in 1200 DEG C of high temperature low pressure working conditions, and sleeve pipe is blocked because shrinking
11, envelope air water pond 35, the diameter of envelope gas hood 19 is both greater than in combustion gas and 1 times of 40 diameter of surge pipe, so in combustion gas and surge pipe
40 just have more than blocking sleeve pipe 11 is shunk, and the pressure regulation amount of 1 times of 19 envelope tolerance of gas hood is sealed in envelope air water pond 35, safety anti-explosive pipe 37
Anti- pressure is just in 9Kg safety coefficients, and system always installs gasket factor and just should be greater than 1 times of safety coefficient, 20Kg pressure is scheduled on, when anti-
When answering the cavity pressure to be more than 9Kg, explosion stack safety disc explosion fuel gas and is burnt in discharge reaction chamber, is not resulted in and is
The destruction and leakage of system are hurted sb.'s feelings, so whole system is safe and reliable.
The present invention is per second can pyrolysis processing 1.5Kg domestic wastes.
