METHOD OF HUMID TREATMENT OF AIR AND CENTRIFUGAL AIR CLEANER Russian patent published in 2009 - IPC B01D45/14 B01D47/06 

FIELD: technological processes.

SUBSTANCE: invention is intended for humid treatment of air or various gases eliminating admixtures, and can be applied in waste gas treatment in various industry spheres, such as agriculture, chemical industry, power engineering and other spheres of economics. Method of humid air treatment involves polluted air flow and fluid sorbent feed onto disc rotor of centrifugal air cleaner, interaction of polluted air with sorbent, separation, and separate discharge of cleaned air and fluid treatment waste. Polluted air and fluid sorbent flows are fed simultaneously in axial direction onto permeable end surface of rotating porous disc, where the flows move inside the porous disc body in radial direction under the effect of centrifugal forces. Intensive flow mixing and physical and chemical interaction takes place. Further additional gas absorption by fine-dispersed sorbent with specified selective properties capable of dissolving admixtures in polluted air and enter physical and chemical interaction with them. After separation cleaned air is blown out into open air via outlet pipe, and cleaning waste are discharged over flush hole and used as target product. Centrifugal air cleaner for implementation of the method includes disc rotor mounted in a case with central gap, rotating on electric engine shaft, polluted air and fluid sorbent feed collectors, and outlet pipe for cleaned air, separation drop collector and discharge hole for treatment waste. Rotor disc is made of porous material permeable in all directions. Polluted air and fluid sorbent feed collectors are mounted along rotor disc axis and can feed air and sorbent onto disc end surface. Collector of fluid sorbent feed has flow controls and conical nozzle with orifices located directly in front of the disc end.

EFFECT: enhanced efficiency and cost efficiency of impurity elimination from gas by humid treatment and reduced aggregate dimensions due to sorbent properties election, obtaining target product from treatment waste.
