Description

[technical field] [0001] The invention relates to the technical field of waste plastic treatment, in particular to a harmless treatment equipment and method for waste plastic. [Background technique] [0002] With the rapid development of social economy, plastic products are used more and more widely in people's daily life, and there are more and more waste plastics. Waste plastic pollution has become a worldwide problem. Since the 1990s, all countries have begun to find effective treatment methods. However, due to the inability to make breakthroughs in key technologies, it is still impossible to completely transform and harmlessly treat waste plastics. Moreover, due to the stable chemical properties of waste plastics, its recycling value is extremely high. At present, waste plastics are generally cracked into low-molecular compounds, and gasoline, diesel oil, liquefied petroleum gas, etc. are obtained through rectification. Cracking treatment is an important way to control ...
