Title:
THERMAL PHASE SEPARATION TREATMENT PROCESS FOR PAINT WASTE RESIDUE AND APPARATUS THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/142657
Kind Code:
A1
Abstract:
A thermal phase separation treatment process for paint waste residue and an apparatus thereof: continuously fed paint waste residue undergoes indirect heating, the moisture and organic matter in the paint waste residue vaporise, and the separated solid residue can be recycled as functional material; pre-cooling treatment is performed on the organic vapour to liquefy and separate macromolecular lipid substances in the gas phase, preventing the macromolecular lipids from blocking the cooling apparatus during a subsequent cooling treatment process, and simultaneously removing some of the water-soluble organic matter, reducing the amount of organic matter entering the aqueous phase, and thus reducing the subsequent water treatment load; after the cooling treatment, the separated gas phase undergoes deep cooling treatment, further liquefying the organic matter in the gas phase; the liquefied non-condensable gas can be recycled as fuel, and most of the organic matter in the gas phase is liquefied and separated by means of continuous cooling treatment, improving the recovery rate and reducing the combustion load; and oil-water separation treatment is performed on the separated liquid phase; the oil can be recycled as fuel, and sewage treatment is performed on the aqueous phase to reduce environmental pollution.
