METHOD OF FOULED AIR CLEANING Russian patent published in 2015 - IPC B01D53/00 

FIELD: process engineering.

SUBSTANCE: invention relates to fanning of industrial structures and can be used for air cleaning of harmful gases and aerosols. Proposed method consists in evacuation of fouled air via one or several air intakes, multistep cleaning of said fouled air of aerosols, fine cleaning of aerosols by sorption bed and collection of solid particles. Mass concentration of aerosols is measured before and after cleaning of fouled air. Note here that fouled air evacuation is initiated with the help of gas photo ionization pickup arranged at every fouled air intake. Said pickup sends the signal to ACS to start air evacuation blower drive motor. Note here that pre-cleaning of aerosols is conducted by electromagnetic separator and fibrous filter. Note also that at fine cleaning, said sorption bed is composed of natural zeolite-bearing rock treated by sulphuric acid flushed with distilled water and calcined at 340-360°C for 5-6 hours.

EFFECT: higher quality of cleaning.
