Harmless disposal technological process for organic synthetic waste

Abstract

The invention discloses a harmless disposal technological process for organic synthetic waste. The harmless disposal technological process comprises the following steps: (1) crushed plastic waste is added into a feeder through a feeding conveying device and pushed into a screw conveying degasser; (2) molten plastic from which harmful gases are removed is continually pushed into a moving-bed cracking plant to be cracked so as to generate cracked gas and powdered carbon residues; (3) the cracked gas is fed into a catalytic tower to produce mixed oil vapor; (4) the mixed oil vapor is continually fed into a fractionating tower to fractionate diesel for collection; (5) the rest mixed oil vapor is continually fed into a condensation tower to separate out gasoline and noncondensable gas; (6) the noncondensable gas is fed into a liquefying system by a compressor to produce liquefied gas, and the liquefied gas is charged into a storage tank; and (7) the removed harmful gas is conveyed into a neutralizing tank to react with a sodium salt solution to produce sodium salt and water. According to the harmless disposal technological process, waste can be effectively separated without landfill or incineration, environmental pollution is avoided, separated light oil and carbon black are effectively reclaimed and utilized, and waste is turned into valuable.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a process flow for harmless treatment of organic synthetic waste. Background technique [0002] At present, the processing methods of waste plastics are mainly divided into landfill method, incineration method, melting regeneration method and chemical recycling method. Landfill and incineration can not fundamentally solve the pollution problem, but also cause a waste of resources. Although the process route of recycling waste plastics is relatively short, the physical properties of recycled plastic products are constantly changing due to the fact that impurities are easily mixed in and degraded and cross-linked during the processing process. Decrease, gradually promote the use value, and eventually become non-renewable garbage plastics, but the chemical energy of these garbage plastics has not disappeared, and there is still great use value.
