SUBSTANCE: invention relates to life support in emergency situations occurring in residential or industrial premises during fires or poisonings. Gist of the invention is that a device for cleaning a room in an emergency situation comprises a spraying device, the input of which is connected to a source of liquid, nozzle atomizers are installed at the sprayer outlet, the axes of which are directed inside the channel formed by the walls of a hollow body. Duct inlet is interconnected with volume of a cleaned room with possibility of ejection of gas from cleaned room into a channel with liquid jets, which are directed into the channel by atomizers of the spraying device. At the channel outlet there is a separator for separation of liquid-gas mixture into liquid and vapor-gas components with the possibility of returning the separated vapor-gas component back to the cleaned room.

EFFECT: increased intensity of gas purification by increasing the specific gas flow through the purification means and, thus, increased 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.
