METHOD OF PURIFICATION OF THE AIR FROM AEROSOL PARTICLES BY INSTALLATIONS OF A PRESSURE PNEUMATIC TRANSPORTATION OF DISPERSIBLE MATERIALS Russian patent published in 2005 - IPC

FIELD: natural gas industry; purification of gases from dispersible impurities.

SUBSTANCE: the invention is intended for purification of gases from dispersible impurities and may be applied in the pressure pneumatic transport systems and production lines of processing of dispersible materials mainly with non-stationary streams. The method of air purification provides for action of inertial forces on a dispersible material in a discharger, withdrawal of the air from the discharging gear and action of the centrifugal forces on the particles in the cyclone apparatus with consequent filtration of the air. Depending on a mode of transportation, 40-80 % of an air stream with the smaller content of the particles are removed from the discharging gear, run through the cyclone apparatus, from which up to 30-90 % of the air stream with the smaller content of the particles fed into the cyclone apparatus are withdrawn and directed for filtration, and 10-70 % from the air stream with high content of the particles fed into the cyclone apparatus are through a damper of braids removed in the filtering dust collector of the cyclone apparatus. Other part of the air stream in amount of 20-60 % with high concentration of the particles is removed from the discharging gear into a collector of the dispersible material, whence it is removed into the cyclone apparatus, from which up to 10-50 % of the air stream with the small contents of p[articles fed into the cyclone apparatus are removed and directed for filtration, and 50-90 % of the air stream with a high content of the particles fed into the cyclone apparatus through the damper of braids removed into the filtering dust collector of the cyclone apparatus. The technical result consists in the continuously high efficiency of trapping of the thinly dispersed materials at different modes of transportation at the constantly high productivity with preservation of the service life of the bag filters.

EFFECT: the invention ensures continuously high efficiency of trapping of the thinly dispersed materials at different modes of transportation and constantly high productivity with preservation of the service life of the bag filters.
