Description

Technical Field

[0001] The utility model relates to the technical field of organic matter separation, in particular to a recovery and treatment device for salt slag produced by stabilizer production. Background Art

[0002] At present, the production line process of chlorinated paraffin supporting stabilizers is that epichlorohydrin and ethylene glycol are reacted through ring-opening addition and closed-loop neutralization to obtain ethylene glycol diglycidyl ether (commonly known as stabilizer), and its main function is to be added to chlorinated paraffin to improve the stability of chlorinated paraffin; but sodium chloride solid will be precipitated during the closed-loop reaction. Since these sodium chloride solids contain a small amount of incompletely separated organic matter (epichlorohydrin, ethylene glycol and ethylene glycol diglycidyl ether, etc.), they are identified as hazardous waste and can only be handled by qualified units.

[0003] However, the current separation technologies involving the separation and removal of organic matter often have high separation costs or harsh application costs. For example, organic extraction technology, through the use of organic extraction separation, separates organic matter and aqueous solution or inorganic solution; the process steps of this method are relatively complicated, which is not conducive to large-scale production. It has certain requirements for the substances to be separated, the conditions are relatively harsh, and the extracted organic matter must be processed later, which is costly. Another example is liquid bubble separation technology, which adsorbs organic matter in the mixture through microbubbles in the liquid, and the bubbles float up to the surface of the liquid, thereby achieving the purpose of separating organic matter. This method separates organic matter; the separation of this method is not thorough enough, and it is impossible to completely separate organic matter. Utility Model Content
