Embodiment Construction

[0058] The present invention will be further described in detail below with reference to the accompanying drawings. The accompanying drawings focus on showing the structure of the entire system in a schematic way and explaining the working principle. Some common components, such as power equipment and transmission equipment of various equipment, are omitted in the drawings, as well as some structures that can be described by text, such as spray humidification, spray cleaning and waste water recycling structures.

[0059] like figure 1 The shown decolorization and regeneration system for waste plastic films includes: a crusher 100 for crushing the film into a specific size; a high-speed centrifugal beating separator 200 for decolorizing the broken film by centrifugal high-speed beating; connecting to the high-speed centrifugal beating and beating separator The collecting and spraying system 300 between the 200 and the residual impurity separation system 400; the residual impuri...

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, in particular to a non-polluting, high-efficiency and strong processing capacity waste plastic film decolorization and regeneration method and a system thereof. Background technique [0002] In the context of the continuous tense energy situation in the world and the record high international oil prices, the realization of circular economy and the effective utilization of resource recycling has become the consensus of people all over the world. With China's entry into the WTO and the trend of economic globalization, the rapid economic development is bound to be accompanied by a large amount of plastic waste, which has seriously affected our daily life and destroyed the ecological environment on which we depend. Recycling waste PET transfer plastic film and using it scientifically and rationally is an effective means to protect the environment and achieve sustainable development. Today's ex...
