Blending auger 26, make the tapered rotary work of blending auger 26, while the envelope gas hood 19 in compression ring type tank 20 is sealed is in water
Middle rotation, tears up rubbish.
First pass through electrical heating and the temperature of high temperature reduction cleaving layer 29 is risen to 1200 DEG C, 1200 DEG C of high temperature is penetrated to upper and lower width
Decay reduces successively, and when upward width is mapped to medium temperature pyrolytic layer 28, temperature damping is to 700 DEG C.
The rubbish torn up through tapered blending auger 26, into medium temperature pyrolytic layer 28, in oxygen-free environment, in 700 DEG C of temperature
Degree is lower to be pyrolyzed into H2、O、CO、CO2、H2O, the trickle material of a grain such as alkane, tar, charcoal.It is swollen that water in rubbish is heated evaporation Peng
Air pressure increases to 3Kg hydraulic pressure values in the high temperature reduction cleaving layer for making all to close.
In the case where tapered blending auger 26 is rotated down 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, and with carbon dioxide reduction reaction generation combustible gas CO occurs for carbon caused by pyrolysis, therefore is arranged without carbon dioxide
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 eliminate 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 to swap out is used for company and outer confession, and combustion gas after cooling is through in combustion gas and surge pipe 40 inserts 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 is exported into market through combustion gas delivery outlet 41 to disappear
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 inadequate, 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 seal air water pond 35, seal the pressure regulation amount of 1 times of 19 envelope tolerance of gas hood, safety anti-explosive pipe 37
Anti- pressure just in 9Kg safety coefficients, always install gasket factor and just should be greater than 1 times of safety coefficient, 20Kg pressure is scheduled on, when anti-by system
When answering the cavity pressure to be more than 9Kg, explosion stack safety disc explosion, discharge fuel gas in reaction chamber and burn, will not cause be
The destruction and leakage of system are hurted sb.'s feelings, so whole system is safe and reliable.
The utility model is per second can pyrolysis processing 1.5Kg domestic wastes.
