FIELD: power engineering.SUBSTANCE: water is sprayed by means of nozzles, and water is collected into a tank for water collection, and air flow is sent towards a water plume by means of a fan, a header of the spray device with nozzles is installed in the upper part of the ventilation cooling tower casing, and above them they install a drop catcher with triple toothing, where air flow changes direction of motion three times, and under the header a sprinkler is installed, which is made in the form of a packet of corrugated and serially connected plates. Water is sprayed by means of nozzles, every of which comprises a casing, a nozzle and an insert swirler coaxial to them, and in the nozzle there is an expanding channel arranged for liquid supply into a cylindrical hole, which is arranged as axisymmetrical to the casing and smoothly changes into a coaxial figured hole made in the form of a Laval nozzle, and in the cylindrical hole of the casing, axisymmetrically to it, there is a cylindrical insert-swirler installed, comprising external peripheral helical threaded channels, besides, along the axis of the insert-swirler there is a central axial hole with the helical thread on the inner surface reverse to the direction of channel threading, at the same time the insert-swirler is installed in the casing via elastic gaskets and is pressed with the nozzle by means of the threaded joint between the casing and the nozzle.EFFECT: cooling tower performance improvement.3 dwg |
