SEPARATOR FOR DRY CHEMICAL CLEANING SYSTEM FOR ARTICLES AND METHOD FOR SEPARATING OF WATER FROM SILOXANE SOLVENT USED IN CHEMICAL CLEANING PROCESS Russian patent published in 2006 - IPC D06L1/08 D06L1/10 B01D17/04 

FIELD: dry chemical cleaning of clothing, in particular, separator and method for extracting of water from solvent in the process of dry chemical cleaning.

SUBSTANCE: separator has main chamber equipped with inlet for receiving mixture of siloxane solvent and water from dry cleaning system and including upper layer and lower layer separated from one another by gravity force and containing siloxane solvent and water, respectively, with water concentration in lower layer being greater than in upper layer, device for adjusting flow of said mixture delivered through said inlet into main chamber and feeding said mixture from main chamber into filter containing material facilitating in coalescence for receiving of mixture forced through by means of device for adjusting flow of said mixture, and additional chamber for further separation of siloxane solvent and water. Additional chamber is connected with filter and is equipped with first inlet adapted for removal from additional chamber of at least upper layer containing siloxane solvent, and second outlet adapted for discharge of water from lower layer of additional chamber onto bottom of main chamber and communicating with third outlet for discharge of water from main chamber. Method for separating of water from mixture of siloxane solvent and water produced after dry chemical cleaning of articles is performed by means of said separator.

EFFECT: increased efficiency in separating of water from siloxane solvent and water mixture through gravitational separation of two mixture components having insignificantly differing densities.
