CHIMNEY-TYPE COOLING TOWER Russian patent published in 2019 - IPC F28C1/00 

FIELD: power engineering.

SUBSTANCE: chimney-type cooling tower contains a case, in the upper part of which there are ionizing nets, covered with a polymer waterproof coating, with corona electrodes connected to a high voltage source and under which the water distribution collector is rigidly fixed, connected to the pressure pipeline of heated water and with the help of a vacuum line – with a vacuum pump rigidly fixed on the outer surface of the housing, the water distribution collector is provided with nozzles oriented downwards, in the lower part of the building there is a zone of regulated air intake containing air inlet windows with rotary valves installed in them, a catchment basin with a chilled water outlet pipeline is located under the chimney-type cooling tower case. Cone-shaped screen is rigidly fixed above the case with the help of vertical racks, along the edge of the base of which a spiral groove is rigidly fixed, the lower end of which is attached to a water intake funnel of a vertical pipe, which is provided with a drainage pipe communicating with, plastic sleeve is installed inside the pipe, fixed with a socket, the narrow part of the socket is mounted on the sleeve, and the wide part is supported on the inner surface of the funnel, which is covered with waterproofing material, inside the plastic sleeve, a power generating unit, made in the form of a stator of a vertical induction motor, is rigidly attached to the inner surface of a vertical pipe, an electrical winding is installed in the slots of the stator magnetic circuit with output terminals to which the load is connected, in the stator bore there is a hollow cylinder, on the outer side surface of which a cylindrical periodic structure of strips of radially magnetized vinyl of alternating polarity is rigidly fixed, the hollow cylinder and the magnetic core are separated by an additional element from composite antifriction non-conducting material that performs the function of a radial-thrust sliding bearing and is integral with the magnetic core and the electric winding, pressure blades are rigidly fixed on the inner surface of the hollow cylinder; the ends of the stator are closed with ring-shaped lids with openings.

EFFECT: invention allows to expand the functions of a cooling tower by converting kinetic energy into electrical energy.
