METHOD FOR CLEANING INDOOR AIR FROM HARMFUL GASES, AEROSOLS, COMBUSTION PRODUCTS IN FIRE AND TECHNOGENIC ACCIDENTS Russian patent published in 2019 - IPC A62B11/00 

FIELD: technology of water and air purification; security facilities.

SUBSTANCE: invention relates to the field of life support in emergency situations arising in residential or industrial premises in case of fires or the entry of poison gas. Method for cleaning indoor air from harmful gases, aerosols, combustion products in case of fire and technogenic accidents is to supply liquid to the atomizing device, spray the liquid in the direction of the channel formed by the walls of the hollow body, thus ejecting the gas from the ventilated room following the jets of the atomized liquid, creating a directed flow of gas and dispersed liquid into the channel of the hollow body, the liquid-gas mixture is collected in a separator installed at the outlet of the channel, the mixture is divided into a liquid and a gas-vapor component, while heat exchange takes place, taking liquid from the gas, and adsorption of impurities from the gas is carried out, and the cooled and purified gas is sent back to the ventilated room.

EFFECT: increasing the intensity of gas purification by increasing the specific gas flow through the purification means and, thus, increasing the intensity of the heat removal from the gas, and also prevention of occurrence of conditions for maintenance of burning by recycling of the cleared gases back in an emergency premise.
