Embodiment

In order to let those skilled in the art can understand technical scheme of the present invention better, the present invention is done further elaboration below in conjunction with accompanying drawing.

As shown in Figure 1; Two-part pyrolytic gasification treatment system of the present invention; Comprise the materials crusher 1, rotating cage type kiln 2, pyrolysis chamber 4, carbon dust jet pipe 6, vaporizer 7 and the gas-purification Heat Room 10 that connect successively; Be provided with gasifier 9 in the vaporizer 7, also comprise being used for dry heat energy being provided and being used for providing the combustion gas transmission pipeline 3 and 5 of combustion material to vaporizer to kiln.Pyrolysis chamber 4 is provided with the combustion gas output channel, this output channel and combustion gas transmission pipeline 3 and 5 UNICOMs; Carbon dust jet pipe 6 one ends connect pyrolysis chamber 4; The other end connects vaporizer 7 tops; Vaporizer 7 bottoms connect gas-purification Heat Room 10, and the gas-purification Heat Room has two output terminals, and the output of first output terminal connects water vapour jet pipe 8; Second output terminal connects combustion header 11, and the water vapour jet pipe the other end connects vaporizer 7 tops.4 tops also are provided with interchanger in the pyrolysis chamber, on the housing of vaporizer 7, also are provided with interchanger, and these interchanger can adopt air blast and water-cooling pattern to reclaim heat energy, for the rotating cage type kiln provides hot blast, are used for dry materials.

Said system works method is following:

1. adopt earlier materials crusher that material is crushed to the granularity of 1-5mm, material is transferred to the rotating cage type kiln through the spiral transmission equipment.

2. after material was sent into the rotating cage type kiln, control rotating cage type kiln working temperature was 120 ℃, with hot blast and radiant baking mode material is carried out fluidized drying, is dried to material water ratio and is lower than 10%; This hot blast derives from the heat energy that follow-up pyrolytic gasification two places reclaim.

3. dried material is sent into through mechanical transfer and carried out pyrolysis in the pyrolysis chamber, pyrolysis chamber's temperature is controlled to be 350-400 ℃.The pyrolytic principle is roughly:

The gas that produces after the pyrolysis is handled through the water washing cleaning mode; Ammonia, stink damp and the hydrocyanic acid gas and the water vapour that produce remain in the washing pool, and inflammable gas is transported to and supplies rotating cage type kiln, self burner, vaporizer burner to use in the combustion gas transmission pipeline; Carbon dust that produces after the pyrolysis and high carbon content polymer powder are transported in the carbon dust jet pipe through the spiral transmission equipment continuously.

4. carbon dust jet pipe and water vapour jet pipe converge at the vaporizer top, and carbon dust mixing water steam sprays into vaporizer, and keeping in the vaporizer is the anoxybiotic state, and the gasifier temperature is controlled at 750-800 ℃ in the vaporizer.On the surface of gasifier 9 of burning red heat, water vapour and carbon dust generation hydration reaction, reaction formula is: 3C+2H 2O---CH 4+ 2CO generates methane and carbon monoxide, and pressure is a little more than normal pressure, to guarantee combustion gas output in the reaction.Generally speaking, 1 ton of water ratio is lower than 10% plant material can produce the combustion gas about 1200 cubic metres, and fuel gases calorific value is about 4000-4300 kilocalories/m 3, wherein the volume ratio of methane is 1/3, and the volume ratio of carbon monoxide is 2/3, and gasification efficiency is very high.The residue after gasifying carbon content generally can reach more than 50%; Output is 10-12% of plant material total amount; Can be used as soil improvement agent and solve the serious problems of domestic present soil depletion, also can be used as the raw material and the WWT of producing the high-carbon fertilizer and use the activated carbon filtration agent.During gasification, can adjust gasification degree at random according to the needs of work purpose, with the combustion gas of regulation and control generation and the ratio of breeze.

5. the pure combustion gas of gasification generation at first gets into the gas-purification Heat Room and purifies also heat exchange production water vapour, and moisture vapor transport is returned the use of vaporizer air feed, and after gas washing purified heat exchange, combustion gas was pooled to the combustion header storage.

According to experiment statistics; The pyrolytic gasification that adopts system according to the invention to carry out plant refuse is handled, and getting into pyrolytic gasification system implants waste water cut is 40%, and dried plant refuse total amount is 70% of a former weight; Pyrolysis weight loss 20%; Carbon dust class material total is 56% of a former weight after the pyrolysis, and vaporization rate is 90%, and primordial plant waste per ton can produce 4000 kilocalories/m only 3Combustion gas 940m 3, reclaim 3,760,000 kilocalories of total heating values, use the combustion gas steam turbine power generation, the generating efficiency of turbine is 35%, the actual power 1530kw.h of system.It is thus clear that pyrolytic gasification treatment system technique effect according to the invention is good, economic benefit is high, flexibility is strong, can realize the maximum recycling of renewable energy source, invests also relatively low.

The not concrete part of introducing all can adopt mature technology means of the prior art among the present invention, repeats no more at this.

The above-mentioned more excellent embodiment of the present invention that is merely; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these changes and distortion all should belong to the protection domain of the appended claim of the present invention.
