APPARATUS FOR REMOVING WATER VAPOURS AND OTHER IMPURITIES FROM FLUE GASES Russian patent published in 2022 - IPC B01D53/60 F23D11/10 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of power engineering and is intended for purifying flue gases from water vapours and other impurities in factory pipes, pipes of NPPs and CHP plants. The apparatus for removing water vapour and other impurities from flue gases comprises a dome at the outlet mouth of the chimney. The dome has a window on top for releasing the purified gas, has an outlet branch pipe located at the preset water level and an additional branch pipe at the bottom for circulation of water in the dome, also containing, in the direction of gas flow, a chimney cap with a blower in the casing thereof and an inverted socket with a temperature sensor and a batch of injection tubes with perforation of the upper ends thereof. Upon activating the apparatus, the dome is filled with water up to the outlet determining the maximum water level in the dome. The injection tubes are installed with the upper perforated ends thereof in the gas zone of the inverted socket, and the lower ends of the tubes put in the water below the preset level thereof. The casing of the blower is connected with the atmosphere by an additional air branch pipe. The water outlet branch pipe, via an additional condensate pipe, is connected with a storage tank, located at the outlet whereof is a pump connected to an additional outlet for circulation of water in the dome via a controlled valve.

EFFECT: invention ensures maximum separation of water vapours and other impurities from flue gases causing significant harm to the environment and the population.
