Description
Technical field
The present invention relates to cracking technique fields, in particular to a kind of cleavage method of organic waste materials.
Background technology
With the development and the improvement of people's living standards of auto industry, vehicle is more and more, and waste tire is also increasingly
It is more, however, for a long time, " the local method oil refining " easily periodically produced floods market, and causes serious security risk and ring
It pollutes in border.The necessary environmental protection facility of Indigenous Smelting Method oil starvation and the facility of safety in production will produce a large amount of in refining process
Generate a large amount of black smokes and pernicious gas, including bioxin, sulfur dioxide, styrene, toluene, methyl sulfide, mercaptan etc..Wherein, two
Evil English is that toxicity is strongest, people be chronically exposed under these pernicious gases have very high chance suffer from various respiratory tracts, neural class,
The diseases such as immune class, reproduction class, disable, be carcinogenic, lethality is far above the resident for living in normal environment, therefore, " Indigenous Smelting Method
Oil ", is forbidded strictly by country.
The organic waste materials such as damaged tire, waste plastics and waste oil burning process and chemical reaction Zhong bioxin be by phenyl ring with
The aromatic compound of the compositions such as oxygen, chlorine, strongest Poisoning is 2,3,7,8- tetrachloro biphenyls (2,3,7,8TCDD).Er Evil
English is not present in nature, is caused completely by artificial pollution.Wherein most important source is, burn containing damaged tire, waste oil,
Waste plastics, especially polyvinyl chloride, polystyrene plastics.Check " bioxin " the more feasible path of generation be to be taken turns useless
The organic matters such as tire, waste plastics carry out anaerobic cracking.There is single pyrolysis amounts for existing cleavage method less, heat transference efficiency is poor,
How the problems such as being pyrolyzed lack of homogeneity is designed and more rational thermal-cracking method is suitble to be the task of top priority.
Invention content
The purpose of the present invention is to provide a kind of cleavage method of organic waste materials, more to the thermal crackings of organic waste materials
Uniform high-efficiency, and the generation of the harmful substances such as bioxin can be effectively avoided, it is suitble to the scale cracking of organic waste materials.
What the embodiment of the present invention was realized in：
A kind of cleavage method of organic waste materials comprising：

Specific implementation mode
It in order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below will be in the embodiment of the present invention
Technical solution be clearly and completely described.The person that is not specified actual conditions in embodiment, builds according to normal condition or manufacturer
The condition of view carries out.Reagents or instruments used without specified manufacturer is the conventional production that can be obtained by commercially available purchase
Product.
A kind of cleavage method of organic waste materials of the embodiment of the present invention is specifically described below.
An embodiment of the present invention provides a kind of cleavage methods of organic waste materials comprising：
The mixture being made of organic waste materials and cracking auxiliary material is cracked under 400~600 DEG C of oxygen-free environment；
Wherein, organic waste materials include at least one of scrap rubber, waste plastics, waste mineral oil and waste edible oil, and cracking is auxiliary
Material includes at least one of broken coal and biological particles.
Preferably, scrap rubber or waste plastics are graininess, and grain size is 0.5~20mm.It is further preferable that grain size be 0.5~
3mm.The grain size of broken coal and biological particles is 0.5~20mm, preferably 0.5~15mm.Of scrap rubber or waste plastic particles
Granule size itself cracking is influenced it is little, as long as not influencing mobility, but smaller particle, such as 20mm hereinafter, into
Heat exchange when row heating is more abundant, is heated also more uniformly.In addition, when the grain size of particle is less than 0.5mm, it be easy to cause object
Flying upward for material, adversely affects production environment.Under considering, size controlling is one in 0.5~20mm and is more managed
The range thought.Meanwhile for this scrap rubber of waste tire, only when granularity is less than 20mm or less, for increasing
The steel wire of tire intensity is just easy to be effectively separated with the mode of machinery, ensure the substance being recovered to respectively and have used in, reach effect
Benefit maximizes, maximum resource utilization.
Further, broken coal includes at least one of lignite, ub-bituminous coal and bituminous coal.Biological particles include stalk, rice
Particle made by least one of grass, rice husk, peanut shell, corncob, oil tea shell and cotton seed hulls.
In order to allow organic waste materials and cracking auxiliary material preferably to mix, reach the best effect to prevent adhesion with thermally equivalent
Fruit, the mass fraction of organic waste materials is 5%~70% in mixture.It is worth noting that, in actual production, organic waste materials
The case where mass fraction is less than 5% can equally be handled with this method, but from the point of view of economical, disposable to handle
Organic waste materials be unfavorable for the control of cost very little, it is preferable that the mass fraction of organic waste materials is 20%~50% in mixture
It is a more suitable range.
Further, best anti-sticking in order to reach when organic waste materials include at least one of scrap rubber and waste plastics
Even effect, should suitably reduce the proportion shared by organic waste materials.Optionally, in mixture organic waste materials mass fraction be 30%~
50%.Meanwhile in order to reach the abundant cracking of solid material, cracking temperature can be relatively high, is set as 500~600 DEG C.
On the other hand, when organic waste materials include at least one of waste mineral oil and waste edible oil, although the case where adhesion
It is less, but when oil is more, material is likely to become fluidised form, is not easy to the conveying of solid material conveyer, it is possible to which appropriate reduce has
Proportion shared by machine waste material.Optionally, the mass fraction of organic waste materials is 5%~20% in mixture.Meanwhile it needing yet
High cracking temperature can set cracking temperature to 400~500 DEG C to reduce energy consumption.
Further, the cracking of mixture is carried out in horizontal revolving kiln, horizontal revolving kiln include cylinder of rotary kiln and
