INSTALLATION FOR PURIFICATION OF THE FLUSHING AND DEFATTING SOLUTIONS Russian patent published in 2008 - IPC C02F1/40 

FIELD: chemical industry; petrochemical industry; building industry; other industries; production of the devices used for purification of the flushing and defatting solutions.

SUBSTANCE: the invention is pertaining to purification of the solutions from the oil products and the suspended substances and may be used at preparation of the workpieces and metalwares for the powder painting. The installation contains the hydrocyclone, the petroleum segregator, the thin-layer shelf settler, the filter of afterpurification linked to the tank of the purified solution. The hydrocyclone is equipped with the pipe duct of feeding of the solution to the purification and is linked by the solution withdrawal pipe duct with the thin-layer shelf settler, and by the pipe duct for the watered oil products - with the petroleum segregator. The thin-layer shelf settler is linked by the pipe duct used for withdrawal of the partially purified solution with the filter of afterpurification. The petroleum segregator is linked by the pipe duct of withdrawal of the settled solution with the thin-layer shelf settler. The hydrocyclone, the thin-layer shelf settler and the filter of afterpurification are linked by the pipe ducts of the sludge discharge with the sludge-collector. The technical result of the invention consists in rise of the purification efficiency of the flushing and defatting solutions.

EFFECT: the invention ensures the rise of the purification efficiency of the flushing and defatting solutions.
