FLUE GAS CLEANING METHOD Russian patent published in 2024 - IPC B01D53/76 

FIELD: various technological processes.

SUBSTANCE: invention relates to methods of cleaning gases and can be used in power engineering during fuel combustion, coke-chemical, coal and chemical industries. Flue gas cleaning method consists in the fact that the cleaned gas is ozonized, then the ozonised gas to be cleaned is alternately exposed to catholyte and anolyte with formation of catholyte and anolyte condensates, which are drained. Cleaned gas is enriched with oxygen by ozonation and removed into the environment. Cold fog of high-pressure catholyte and cold fog of high-pressure anolyte are used for alternate action on purified gas. For even more effective cleaning, it is advisable to perform alternate action on the ozonized gas to be cleaned at least twice with cold mist of catholyte and at least twice with cold mist of anolyte. When cleaning large amounts of flue gas, the purified gas after ozonation is expediently divided into two or more streams, and the specified alternate action is carried out on the purified gas of each stream.

EFFECT: invention provides higher degree of purification of large amounts of flue gases due to provision of alternate action on them of cold fog of high pressure of catholyte and anolyte, which is a fine fog of oppositely charged electrolytes with high ORP.
