CLASSIFIER FOR SEPARATING PURIFIED SMOKE GASES INTO NITROGEN AND CARBON DIOXIDE GAS Russian patent published in 2017 - IPC B01D53/00 

FIELD: power industry.

SUBSTANCE: classifier for separating purified smoke gas into nitrogen and carbon dioxide gas is a casing equipped with gas nozzles for purified gas inlet, nitrogen outlet, carbon dioxide outlet and fittings for feeding the rinse water and removing the carbonized water inside which, from the bottom to the top, a pan, a carbon dioxide chamber with a demister, separated with horizontal partition with round gas holes, a receiving chamber, carbon dioxide capture stages, which are horizontal perforated partitions with slotted and round holes, covered with a layer of granulated blast-furnace slag of h height and nitric chamber with spray are installed in sequence. Whereby, the carbon dioxide capture stages are connected to the carbon dioxide chamber with downcomers, which are damped with plugs at the nitrogen chamber inlet. Downcomers` areas, passing through layers of granulated blast-furnace slag, are provided with slotted holes of height less than h along the entire perimeter. In the horizontal partition, separating the receiving chamber from the carbon dioxide chamber, the drain valves are arranged, each of which consists of a drain hole in a horizontal partition, a grill frame, attached to it, and a float valve placed in the frame.

EFFECT: increased performance of the device.
