PROCESS FOR REMOVING DEPOSITS FROM TUBE SURFACES Russian patent published in 2006 - IPC C23G3/04 B08B9/02

Abstract RU 2280101 C2

FIELD: removal of different type deposits from metallic surfaces.

SUBSTANCE: process comprises steps of leaching deposits by means of activated water. Water is subjected to activation in rotor type cavitation apparatus in closed circulation circuit at presence of lignosulfonate suspension, 0.4 - 2 mass % and coal suspension, 0.5 mass % and at revolution number of rotor of cavitation apparatus in range 3 000 - 6 000 rev/min, cycle quantity 5 - 35 and temperature 17 -68°C.

EFFECT: enhanced efficiency of cleaning tube surfaces by removing deposits.
