METHOD OF IMPROVEMENT OF EFFICIENCY OF AIR PURIFICATION IN MULTI-TEMPERATURE CONDENSING CHAMBER Russian patent published in 2015 - IPC B01D47/05 

FIELD: ventilation.

SUBSTANCE: method consists in cooling and supersaturation of the purified flow with water vapour at its passing through the humidifier and the multi-temperature condensing chamber with the gas path of mainly rectangular section the opposite adjacent walls of which have different temperature, with the subsequent separation from the flow of solid and condensed phases. The upper and lower bottoms of the chamber are connected among themselves by peripheral part by means of sidewalls with formation of closed cavity in walls of which the sockets are made to ensure the possibility of supply of working body and measuring instruments inside the cavity of pipelines, path sidewalls consist of several parts which are movably connected among themselves with a possibility of angular and radial movements both inside, and outside of the gas path. The path is formed by upper, lower bottoms and sidewalls of the path, the path length is changed by movement of inlet part in the radial direction, and path geometry is changed by means of movement of sidewalls in the axial, radial and angular directions, meanwhile the pressure in the path of the multi-temperature condensing chamber and in the closed cavity is supported equal. The steam-air flow in the chamber is additionally turbulised and mixed due to installation in the central part of the chamber of additional edge by means of which the chamber cavity is separated into two parts, and the named edge is implemented with a possibility of the interconnection of parts of the chamber cavity among themselves. The named edge is set along its longitudinal axis, mainly parallel to it, with the shift towards the hot sidewall of the path from the longitudinal axis to the distance x=(0.1…0.3)X, where x - distance of shift of the edge towards the hot sidewall, X - channel width.

EFFECT: method allows to provide higher air purification.
