PNEUMOPULSE SYSTEM FOR BREAKING MATERIAL BRIDGES AND CLEANING SURFACES OF APPARATUSES FROM DEPOSITS Russian patent published in 2007 - IPC F15B21/12 F28G1/16 

FIELD: chemical, metallurgy, mining and other industries.

SUBSTANCE: invention relates to devices for pneumopulse breaking of material and cleaning surfaces of apparatuses from deposits. Proposed pneumopulse system contains row of containers connected in succession and furnished with exhaust nozzles, elastic diaphragms, prechamber and working space. First container is connected with union to deliver compressed air. System in furnished with elastic diaphragms with valves dividing each container into prechamber and working space. Each container is provided with intake chamber divided by elastic diaphragm into intake space and adapter chamber communicating with prechamber through hole in its central part, and by means of holes on side surface, with atmosphere. Working space of each preceding container communicates through pipeline with valve with intake space of each following container, intake space of first container communicates through control valve with atmosphere and intake chamber, working space and prechambers of all containers are connected by throttling unions with compressed air delivery pipeline.

EFFECT: improved efficiency of material bridge breaking and cleaning of surfaces of apparatuses from deposits.
