Apparatus for heat-mass exchange processes with participation of liquid

An apparatus for heat-mass exchange processes employing a liquid, comprising:

• a casing;
• means for introducing process source materials into said casing and discharging the final products thereform;
• at least one sprinkling device installed within said casing for rotation about its axis;
• chutes forming said sprinkling device, curved into a multiple-start spiral, diverging from the axis of said sprinkling device whereby hollows formed in said chutes are located on the concave side of the spiral;
• gaps being formed between coils of said sprial, and means for supplying a liquid to a central part of the sprinkling device, wherein:
• at least peripheral portions of at least two of said chutes gradually recede from the axis of said sprinkling device and are displaced in a direction parallel to the axis of said sprinkling device;
• and the other ends of said chutes are located in different planes perpendicular to the axis of said sprinkling device.
