Innocent treatment and oily recovery device of polymer waste

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...

AI Technical Summary

Problems solved by technology

However, the recovered oil components are relatively complex and not very practical. If the oil can be directly separated and recovered in the whole set of recovery equipment, for example, different oils can be separated according to the difference in boiling point and harmless treatment can be carried out. Then the obtained product The application value will be very high
