Description

A kind of combustion chamber of plastic garbage pyrolysis furnace

Technical field

The invention belongs to field of garbage disposal, it is more particularly to a kind of by plastic garbage continuous processing and comprehensively utilize method In plastic garbage processing system in plastic garbage pyrolysis furnace combustion chamber.

Background technology

Plastic garbage is one of rubbish common in daily production and life, due to the degradability that is difficult to of plastic garbage, mesh The method of pre-treatment plastic garbage is mainly using landfill, burning, the method cracked；Landfill method is that plastic garbage is bought in into underground, By its natural degradation, such way time cycle length, have greater environmental impacts, land occupation；Combustion method is by plastic garbage Burnt, either with Other Waste or the combust of material one, as generating or other thermals source, such way is due to modeling A large amount of toxic gases can be produced after material burning, secondary pollution is caused to environment；The method of cracking, it is that plastic garbage is put into cracking Stove, plastics are decomposed again, petroleum substance is produced after decomposition, fuel or other raw materials can be used as to reuse；Existing Method for cracking treatment in, problems be present, first, existing complete continuous cracking equipment is to plastics in plastic garbage Composition requires, that is to say, that, it is desirable to the uniformity of the plastics variety in plastic garbage will get well, the ratio containing certain plastic components Example is needed to reach more than 85%, and this can be realized, for refuse classification for the good country that refuse classification is done Incompact country that is bad or doing is difficult to realize；It is existing if such component requirements can not be reached Cracking apparatus cannot realize the cracking of plastic garbage, gently then equipment does not work, heavy then cause equipment explosion；It is furthermore right Substantial amounts of toxic gas is produced in the processing method discontinuously cracked, cracking process can still be discharged into air, to environment Secondary pollution is caused, while strong acid is produced after these toxic gases chance water, causes equipment corrosion serious, shortens equipment and use the longevity Life；3rd, due to different plastic components in cracking be present, and cracking temperature is merely able to adapt to the cracking temperature of a certain plastics Degree, it is impossible to the cracking of plastic garbage is realized on a pyrolysis furnace, while needs to be sorted plastics variety, it is residual after cracking Slag is easily bonded on furnace wall, causes pyrolysis furnace to damage, while the residue for clearing up furnace wall will also result in the secondary pollution of environment；The 4th, the sorting of existing plastic garbage is the method by the way that plastic garbage is crushed, and so consumption energy is big, causes the energy unrestrained Take.

To solve the above problems, the applicant have submitted Application No. " 2017104731616 ", a kind of entitled " plastics The Chinese invention patent application of waste cracking furnace ", the pyrolysis furnace of the plastic garbage processing system of the patent application publication, the modeling Material refuse disposal system can realize the continuous cracking of multicomponent plastic garbage, and not discharge any pollution environment in cracking process Solid, liquids and gases, realize the comprehensive utilization of plastic garbage, save the energy, still, existing plastic garbage pyrolysis furnace Combustion chamber in use, plastic garbage cracking caused by oil and high-temperature gas combustion chamber can be caused to corrode, cause The problems such as combustion chamber is fragile, and service life is short, and combustion chamber is once corroded damage, it, which is repaired, changes very difficult, maintenance It is with high costs.
