Description
Technical field
The present invention relates to organic matter technical field of energy utilization more particularly to a kind for the treatment of process of solid waste.
Background technology
Burning is the integrated disposal processing of organic solid waste pyrolytic and deep oxidation greatly, and benefit is a large amount of harmful
Scrap digestion and become harmless substance.With such processing method, solid waste is taken up an area less, treating capacity is big, but is burned
There is disadvantage, the smoke evacuation of existing common burning method can cause secondary pollution, and equipment corrosion phenomena is serious.Pyrolysismethod is to utilize
The thermal instability of organic matter in organic solid waste is carrying out heating distillation to it, so that organic matter is generated cracking, after condensed
Various new gases, liquid and solid are formed, the process of fuel oil, combustible gas is therefrom extracted.With such processing method, will produce
The substances such as tar, processing are complicated.
Invention content
The object of the present invention is to provide a kind for the treatment of process of solid waste, by organic dirt in organic solid waste
It contaminates the factor to eliminate, achievees the purpose that environmental protection.
Technical scheme of the present invention：A kind for the treatment of process of solid waste, which is characterized in that include the following steps：
（1）Pretreatment：Organic solid castoff is dried, is crushed, deodorizing process；
（2）Pyrolytic gasification：Pretreated organic solid castoff is subjected to pyrolysis processing, at the laggard promoting the circulation of qi of pyrolysis processing
Reason, is passed through vapor and quartz sand during gasification, and solid waste becomes high-temperature flue gas or ash content after pyrolytic gasification,
High-temperature flue gas is discharged from the top vent of solid waste pyrolysis gasifying device, and ash content and quartz sand are pyrolyzed from solid waste
The discharge gate of gasification installation is discharged, after cooling screening detaches ash content, quartz sand circulating and recovering；
（3）Cracking is reformed：To the high-temperature flue gas after pyrolytic gasification, cracking reformation is carried out under the effect of the catalyst；
（4）Post-processing：Gas cooling, the purification generated after cracking is reformed.
A kind for the treatment of process of solid waste above-mentioned, which is characterized in that the step（1）In, by solid waste
Drying to moisture content is 5-20%, and it is 0.5-5mm to be crushed to particle size range.
A kind for the treatment of process of solid waste above-mentioned, which is characterized in that the step（2）In, the mistake of pyrolysis processing
Oxygen content in journey<5%, the temperature of pyrolysis processing is 500-1000 DEG C, and the time of pyrolysis processing is 60-120min.
A kind for the treatment of process of solid waste above-mentioned, which is characterized in that the step（3）In, crack the temperature of reformation
Degree is 1000-1200 DEG C, reformation time 10-30s.
A kind for the treatment of process of solid waste above-mentioned, which is characterized in that the step（3）In, catalyst is nickel salt
At least one of catalyst and iron salt catalyst.
Beneficial effects of the present invention：It, will be organic in pyrolytic process to the technique of organic solid waste progress harmless treatment
The organic contamination factor contained by solid waste is eliminated, while material reaction environment is reduction-state, evades the generation of bioxin, keeps away
Secondary pollution of the disposal process to environment, obvious environment benefit are exempted from.
Specific implementation mode
The present invention is further illustrated for following example, but is not intended as the foundation limited the present invention.
Embodiment：A kind for the treatment of process of solid waste, includes the following steps：
