MULTI-FUNCTIONAL APPARATUS WITH COUNTER SWIRLING FLOW Russian patent published in 2008 - IPC B01D47/06 

FIELD: heating, ventilation.

SUBSTANCE: invention is referred to ventilation and conditioning of air with regenerative heat recovery units. Multi-functional apparatus with counter swirling flows of treated air consists of two treatment stages. First stage includes top and bottom sleeves provided with tangential vortex generators, and centrifugal tangential injectors. Second stage contains centrifugal stirring chamber with inlet sleeve provided with tangential vortex generator, diffuser, convergent pipe, untwisting element and outlet sleeve. Diameter of centrifugal stirring chamber is bigger than the diameter of the first stage housing. Apparatus also includes preparation system for dispersed circulating water consisting of shutoff valve, sediment chamber, filter, and circulation pump and make-up valve for compensation of water resource.

EFFECT: possibility of discharged heavily dust-loaded air heat recovery, saving of energy resources and simplification of air conditioning system design, installation and maintenance.
