BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste plastic regeneration vessel, and more particularly, to a waste plastic regeneration vessel that contributes to prevention of marine pollution by collecting and regenerating waste plastic floating on the ocean in the field, .

In general, plastics are used in a wide variety of uses and functions as a base material because of their properties such as corrosion resistance, corrosion resistance, workability and low specific gravity. These plastics are pyrolyzed at specific temperatures to produce various low molecular weight compounds.

As a result, they cause the formation of a safe ground, Which causes air pollution. Therefore, in order to solve these problems, many studies and efforts are being made to regenerate waste plastics. For example, the recovered waste plastic melts and decomposes when put in an oil solvent heated to about 200 ° C. When the waste plastic is vaporized for purification and then cooled to be condensed as a liquid, it can be reused as fuel, .
