Document Type and Number:
WIPO Patent Application WO/2021/261899
Kind Code:
A1
Abstract:
The present invention relates to a pipe washing device for waste plastic and a waste vinyl emulsification facility, the device comprising: a heating unit that produces an emulsified gas by stirring and heating waste plastic and waste vinyl with a solvent; a gas separation unit that separates the heated emulsified gas into a heavy oil gas and a light oil gas; a first connection pipe; a cooling unit that cools the light oil gas and moisture contained therein so as to liquefy the gas; a second connection pipe; an oil storage unit that stores the liquefied oil and moisture; a third connection pipe; an oil-water separation unit that receives the liquefied oil and moisture stored in the oil storage unit and separates same from each other so as to obtain the liquefied oil; a pump unit which is disposed on the third connection pipe; and a fourth connection pipe. The pipe washing device may further comprise, on the other end of the fourth connection pipe, a spray nozzle unit which is inserted into the first connection pipe, has a lower outer surface that is at least partially in contact with the inner bottom surface of the first connection pipe, and is capable of spraying the oil and moisture liquefied by the pump unit at a predetermined pressure to the bottom surface of the inside of the first connection pipe. Accordingly, the liquefied oil and the moisture contained therein are sprayed at a high pressure to the connection pipe between the gas separation unit and the cooling unit, such that deposits such as carbon, heavy metals, dusts, or wax components are not precipitated.
