Abstract
The invention relates to a treatment method of solid organic wastes. The solid organic wastes are put in a pyrolyzing furnace to generate pyrolysis gas. The method does not have obvious stages, and many reactions are performed alternately, which has many similarities to pyrolysis of coal. The method is characterized in that rubber and plastics in municipal solid wastes contain more hydrogen and less oxygen, thus, more oils exist in the pyrolysis products, and the gas has higher heat value; and other wastes contain more oxygen and less hydrogen, so that the gas has lower heat value.
Description
Technical field
The present invention relates to a kind of refuse processing method, particularly a kind of solid organic castoff treatment process.
Background technology
China only, from " seven, five ", just carries out systematic study to the solid organic castoff pyrolytic technique, except my institute, also has Tongji University, University Of Chongqing carrying out similar pyrolytic gasification research, but also putting into operation without the industrialness device.Can think in the world, solid organic castoff pyrolysis processing technology has entered industrialization phase and has progressively updated, and China heuristics and the technical reserve stage such as lab scale with also stopping.
Summary of the invention
Technical problem to be solved by this invention is to provide the solid organic castoff treatment process that a kind of efficient and convenient rate of decomposition is high.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of solid organic castoff treatment process, solid organic castoff is put into to pyrolysis oven, and produce pyrolysis gas.
The invention has the beneficial effects as follows: there is no fairly obvious stage, many reactions intersect to be carried out, the pyrolysis of this and coal, many similarities are arranged, difference is: in municipal solid wastes, in rubber, plastics, protium is relatively many, and oxygen element is less, thereby in its pyrolysis product, oils is more, and gas heating value is higher, and the oxidation element is more for other waste, protium is relatively less, and gas heating value is also just low accordingly.
Further, described solid organic castoff falls into after pyrolysis oven stablizes reactor, and the waste slag after processing is got rid of.
Further, described pyrolysis gas is through dedusting, degummed oil, except dry after hydrogen sulfide and ammonia, cooling rear gas recovery.
Further, described pyrolysis oven internal pressure is 0.
Further, described pyrolysis temperature is 55 ° to 850 °.
The accompanying drawing explanation
Fig. 1 is schema of the present invention;
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of solid organic castoff treatment process, put into pyrolysis oven by solid organic castoff, produces pyrolysis gas.Further, described solid organic castoff falls into after pyrolysis oven stablizes reactor, and the waste slag after processing is got rid of.
Further, described pyrolysis gas is through dedusting, degummed oil, except dry after hydrogen sulfide and ammonia, cooling rear gas recovery.
Further, described pyrolysis oven internal pressure is 0.
Further, described pyrolysis temperature is 55 ° to 850 °.

Technical analysis and no element analysis
The invention has the beneficial effects as follows: there is no fairly obvious stage, many reactions intersect to be carried out, the pyrolysis of this and coal, many similarities are arranged, difference is: in municipal solid wastes, in rubber, plastics, protium is relatively many, and oxygen element is less, thereby in its pyrolysis product, oils is more, and gas heating value is higher, and the oxidation element is more for other waste, protium is relatively less, and gas heating value is also just low accordingly.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
