FIELD: machine building. ^ SUBSTANCE: invention can be implemented for cooling return water in cooling towers of power and other industrial plants, for example, in heat power plants (HPP) and nuclear plants (NP). Here is disclosed the sprinkler of the cooling towers for heat- and mass -exchange processes made as units, inside of which there are arranged contacting surfaces out of synthetic woven cloth made corrugations-like with radius of curvature 19-31.4 of corrugation length. Vertexes of corrugations are located on vertical partitions of end sides of the unit. The units are arranged in rows one beneath another and contacting with their end sides at off set along vertical for width of a band. In whole they form tiers. An additional tier is perpendicular at a distance of 0.5-1 of unit height. The unit consists of two contact surfaces in form of bands, each with width from 0.2 to 0.5 of width of a vertical partition, the bands are secured along their width on upper and lower ribs of opposite vertical sides of the unit, forming corrugations. Vertexes of corrugations are bent at 90 and are attached to vertical partitions of opposite vertical sides. The corrugations are set off vertically at 0.5 of length of a contacting surface. ^ EFFECT: reduced hydraulic resistance of cooling tower sprinkler by increase of specific surface of interacting phases, by creating additional channels for gas flowing and by equalising field of gas velocity through all section of unit. ^ 4 dwg |
