METHOD OF CLEANING VESSEL INNER SURFACE Russian patent published in 2013 - IPC B08B9/08 

FIELD: process engineering.

SUBSTANCE: invention relates to destruction of packed loose material in hard-to-access points of the vessel. Proposed method consists in mounting air gun with nozzle coupled with bin filled with kinetic elements via pneumatic line in said vessel. Camera or remote pickup are used to detect packed material at vessel walls to transmit appropriate signal to control unit that positions air gun nozzle in required direction. Compressed air source creates pressure in air line to feed kinetic element into air gun and, via said nozzle, to packed material. Kinetic elements used are granulated material or similar composition and/or origin with packed material.

EFFECT: higher reliability and quality.
