MULTI-CIRCUIT EJECTION COOLING TOWER Russian patent published in 2013 - IPC F28C1/00 

FIELD: power engineering.

SUBSTANCE: multi-circuit ejection cooling tower comprises a body in the form of a regular polyhedral prism based on supports, comprises two reservoirs in the lower part for collection of cooled water - outside a pool of polyhedral shape, which belts a receiving chamber along the cooling tower contour placed in the centre, from which cooled water is supplied to a load, in the upper part the body changes into a confusor, narrowing of which covers a drop catcher, and above the confusor there is an exhaust channel. The cooling tower has two cooling circuits - internal and external, separated with a partition, arranged concentrically to body walls along its entire height, in the lower part of the separating partition along its perimetre from inside there are inclined spillways mounted in the form of a truncated tilted pyramid, outside of the partition, and along the contour of the body walls from inside at the same level, there are also spillways mounted with inclination towards each other, above spillways there are ejection units, and directly under them there are headers of the water-distribution system in the form of closed octahedrons, in the projection link under spillways, at the level of top of water-collecting reservoirs there are technological sites - internal and external, besides, decking of the external site is solid and covers the peripheral part of the pool surface, and decking of the internal one is latticed, between lower edges of all spillways and contours of technological sites there are wind partitions installed, which prevent steam and drop moisture carryover from the volume of the cooling tower, at the same time in the space above the internal technological site under adjacent spillways there is a water-intake corridor.

EFFECT: improved operational and technical characteristics of a cooling tower, reduced capital costs for construction, higher cooling capacity of a cooling tower, improved conditions of device maintenance.
