Embodiment Construction

[0058] The present invention will be further described in detail below in conjunction with the accompanying drawings. The emphasis of the accompanying drawings is to show the structure of the entire system in a schematic manner and explain the working principle. In the drawings, some common components are omitted, such as the power equipment and transmission equipment of each equipment, and some structures that can be explained by text, such as spray humidification, spray cleaning and waste water recovery, etc. are omitted.

[0059] Such as figure 1 A waste plastic film decolorization regeneration system shown includes: a crusher 100 for crushing the film into a specific size; a high-speed centrifugal beating separator 200 for centrifugally beating and decolorizing the crushed film at high speed; connected to the high-speed centrifugal beating separator The collection and spraying system 300 between 200 and the residual impurity separation system 400; the residual impurity sep...

Abstract

The invention belongs to the field of waste plastic regeneration, and particularly relates to a waste plastic film decolouring regeneration method and a waste plastic film decolouring regeneration system which are pollution-free, efficient and high in treatment ability. Waste plastic films are processed by a physical method, the colour or metal coating covered on the surface of the film is fallen off in a mechanical flapping or mechanical friction manner. In order to completely remove the colour or metal coating covered on the film in a physical manner, the recovered waste film is firstly crushed into small blocks, and the coating on the film fragment is more likely to fall off in the high-speed mechanical flapping and friction process. By the method, the defect that long-time chemical reaction is required according to the conventional chemical method is overcome, the colour or metal coating on the film can be efficiently removed, and the method is suitable for batch industrial process and can be used for treating a large amount of waste plastic garbage.

Description

technical field [0001] The invention relates to the field of waste plastic recycling and regeneration, in particular to a pollution-free, high-efficiency and strong processing capacity waste plastic film decolorization regeneration method and system thereof. Background technique [0002] In today's world where the energy situation continues to be tense and international oil prices hit new highs, circular economy and the realization of resource recycling and effective utilization have become the consensus of people all over the world. With China's accession to the WTO and the trend of economic globalization, the rapid economic development is bound to be accompanied by a large amount of plastic waste. At the same time, it has seriously affected our daily life and destroyed the ecological environment we depend on for survival. Recycling waste PET transfer plastic film and using it scientifically and rationally is an effective means to protect the environment and achieve sustain...
