Abstract

The invention discloses an innocent treatment and oily recovery device of polymer waste, comprising a dry distillation and thermal decomposition system, a high-boiling-point oil recovery system and a low-boiling-point oil recovery system. The innocent treatment and oily recovery device is characterized in that three systems are connected in sequence; finally, oily recovery is carried out on the polymer waste according to difference of boiling points, after the polymer waste is thermally-decomposed by low-temperature dry distillation in the dry distillation and thermal decomposition system, the generated thermal decomposition gas is temperature-controlled and is subjected to backflow by the high-boiling-point oil recovery system so as to realize separation of low-boiling-point oil and high-boiling-point oil; and low-boiling-point is cooled and condensed in the low-boiling-point oil recovery system and then is further recovered as low-boiling-point oil. In the innocent treatment and oily recovery device, the operating efficiency of the equipment is high, the separation and the modification of the low-boiling-point oil and the high-boiling-point oil can be successfully realized, low energy consumption is realized by heat circulation, and therefore, the device disclosed by the invention is a novel innocent treatment and oily recovery device.

Description

technical field [0001] The invention relates to a harmless treatment and oil recovery device for polymer waste such as waste plastics and waste rubber, more specifically, it relates to a device for generating pyrolysis gas through low-temperature dry distillation of polymer waste, and High-efficiency separation and recovery of high-boiling point oil and low-boiling point oil oil treatment device. Background technique [0002] Resource reuse is the premise of sustainable development, and the treatment and reuse of polymer waste is the research focus of resource reuse. Polymer waste includes not only single-material polymer waste such as plastics and rubber, but also composite waste of inorganic polymer materials and inorganic materials such as metals and ceramics. [0003] There is already a corresponding technology for reusing polymer waste, such as the Chinese patent application No. 97182331.6 titled "Method and Equipment for Preparation of Hydrocarbons from Organic or Pol...
