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 underground, By its natural degradation, such way long time period has greater environmental impacts, land occupation；Combustion method is by plastic garbage Burning either, either one combust of material is as power generation or other heat sources with Other Waste, and such way is due to modeling A large amount of toxic gases can be generated after material burning, secondary pollution is caused to environment；The method of cracking is that plastic garbage is put into cracking Plastics are decomposed, petroleum substance are generated after decomposition by stove again, fuel or other raw materials can be used as to reuse；Existing Method for cracking treatment in, have the following problems, first, existing complete continuous cracking equipment is to plastics in plastic garbage Ingredient requires, that is to say, that, it is desirable that the consistency of the plastics variety in plastic garbage will be got well, the ratio containing certain plastic components Example needs to reach more than 85%, this can be realized, for the good country that garbage classification is done for garbage classification 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 lead to equipment explosion；It is furthermore right A large amount of toxic gas is generated in the processing method discontinuously cracked, cracking process can still be discharged into air, to environment Secondary pollution is caused, while strong acid is generated after these toxic gases chance water, leads to equipment seriously corroded, shortens equipment and use the longevity Life；Third, since, there are different plastic components, and cracking temperature is merely able to adapt to the cracking temperature of a certain plastics in cracking Degree, it is impossible to the cracking of plastic garbage is realized on a pyrolysis furnace, while needs to sort plastics variety, it is residual after cracking Slag is easily bonded on furnace wall, and pyrolysis furnace is caused 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 the consumption energy in this way is big, causes the energy unrestrained Take.

To solve the above problems, the applicant has submitted, application No. is " 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 do 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, the oil that generates and high-temperature gas can cause to corrode to combustion chamber when plastic garbage cracks, and cause The problems such as combustion chamber is fragile, and service life is short, and combustion chamber is once corroded damage, very difficult, repair is replaced in repair It is with high costs.
