KOCHETOV'S MECHANICAL-DRAFT TOWER Russian patent published in 2015 - IPC F28C1/00 

FIELD: machine building.

SUBSTANCE: mechanical-draft tower consists of a housing, sprinkling device, liquid-collecting tank and fan. The case is composed of two parts - an upper one including a sprinkler and a droplet separator between which the manifold of sprinkling device with nozzles is mounted, and a lower part wherein the cooled water collecting tank with a fan mounted on it is arranged. Also, the fan is made from sheet stainless steel. A diffuser is installed into the collecting tank. The diffuser is a part of the housing and connected with the fan. The fan is fitted with a plastic working wheel and a multi-speed electric engine. Depending on weather conditions during operation the engine changes output of the tower due to change of air flow rate. and droplet separator is designed with triple corrugation, where the air flow three times changed its motion direction and at the expense of it the significant decrease of droplet carry-over is achieved, each of nozzles of the spraying device is designed with spraying disk and contains the cylindrical housing with the union rigidly connected to the housing and axially located in upper part of the housing, with a cylindrical hole for liquid supply, connected with the diffuser, axisymmetrical to the housing and union, and to the housing, in its lower part, by means of, at least, three spokes the sprayer located perpendicularly to the housing centreline and designed as a continuous disk is connected.

EFFECT: raised efficiency of mechanical-draft tower operation.
