Technology for extracting gasoline diesel by using waste plastic in domestic garbage landfill site

Abstract

The invention discloses a technology for extracting gasoline diesel by using waste plastic in a domestic garbage landfill site. The technology comprises the following steps of pretreating the waste plastic, splitting the waste plastic, performing catalyzing fractional distillation, and recovering petroleum gas of the waste plastic. According to the technology disclosed by the invention, the waste plastic is splitted, and petroleum products of gasoline, diesel and the like are obtained through recovery. Waste residues discharged from a cracking furnace can also be processed into burn-free sewer line products special for cities, and collected and screened waste fertile soil is directly fermented so as to process an organic fertilizer. In the entire process, secondary pollution is not generated. The technology has the advantages of being low in cost, environmental-friendly, and energy-saving, and turning waste into wealth. The technology not only is considerable in economic benefits, but also effectively treats garbage in the domestic garbage landfill site, so that atmospheric pollution is reduced, and the original appearance of soil of the garbage landfill site is basically restored, sustainable development is realized, and the technology is favorable for human, and has long social and environmental-friendly benefits.

Description

technical field [0001] The invention relates to the technical field of processing waste plastics, in particular to a process for extracting gasoline and diesel from waste plastics in domestic garbage landfills. Background technique [0002] The practice of simple stacking and disposal of domestic waste is extremely unscientific, which will not only cause serious pollution to the environment, but also take up a lot of valuable land. At present, in the utilization of waste plastics, methods such as regeneration, burial, and incineration have been adopted. The quality of the plastic products obtained by the recycling method is poor; the natural degradation rate of the plastic in the burying method is too slow, and the plastic remains in the soil for a long time and cannot be decomposed, which makes the soil harden seriously. The most important thing is that after the service period expires, it still needs to invest in the construction of a new landfill, further occupying land ...
