APPARATUS FOR SEPARATING OIL PRODUCTS AND MECHANICAL IMPURITIES FROM WATER Russian patent published in 2014 - IPC B01D17/28 

FIELD: chemistry.

SUBSTANCE: apparatus consists of a vessel 1 and a tank 2 with a cover 3, a spout 4 and a spout cover 5, on which is attached a vertical pipe 6 with a damper 7. On walls of the tank 2 there are drain pipes for water 8, oil products 9 and 10 and pipes 11 and 12 for removing solid deposits. Inside the tank 2 there is a vertical partition 17 with spacing from the bottom, which forms a chamber for storing separated water, and a vertical partition 18, which is sealed to the bottom and side walls of the tank 2. On the partition 18 there are single-level end-to-end channels connected by pipes to a pipe 19 which is perforated on the side of the bottom. The single-level channels are enclosed by a box 20 which is open on the lower face. In the lower part of the chamber between partitions 17 and 18 there is an aeration device which consists of inlet perforated pipes 21 with dispersing elements mounted thereon.

EFFECT: high efficiency of separation.
