BAG FILTER WITH IMPULSE RECOVERY FOR DUSTY GAS CLEANING Russian patent published in 2011 - IPC B01D46/02 

FIELD: process engineering.

SUBSTANCE: invention relates to dusty gas cleaning and may be used in chemical and food industries, metallurgy, as well as in production of construction materials. Proposed bag filter comprises cylindrical case with screen to divide said case into dusty and clean gas chambers, filter sleeves stopped from below, regenerator, tapered dust collector with gate, blowing tubes with electromagnetic valve and receiver, as weal and dusty gas feed and clean gas discharge branch pipes. Filter sleeves are pulled on metal frame made up of a coil fitted on said screen, sleeve top parts are secured to said frame by clamp and arranged coaxially in metal or polymer shells with open bottom. Truncated-cone ejecting nozzles are arranged in top part of said shells. Distance from filter sleeve to said shell is selected so that to allow gas flow rate of 25-75 m/s.

EFFECT: higher efficiency of cleaning and regeneration.
