HEAT-MASS-EXCHANGE UNIT OF THE EJECTION COOLING TOWER Russian patent published in 2022 - IPC F28C1/00 

FIELD: power engineering.

SUBSTANCE: invention relates to thermal power engineering and can be used in ejection cooling towers. In the heat-mass-exchange unit, which is two rows of small-sized ejection units mounted on opposite spillways with a slope towards each other, the ejection unit consists of an air intake window, an ejection channel, a beam collector and injectors. The rectangular air intake window, with flanges on three sides, is the basis for basing the ejection channel. Inside, the window has a symmetrical opening also with a closed wave-shaped flange. The contour of the window is formed as a result of the intersection of several circles of the same radius, the centers of which lie on the axis of symmetry oriented across the spillway. The walls of the ejection channel are also of a closed wave-like shape installed concentrically to the opening of the air intake window. In the centers of the circles forming the window opening, there are nozzles mounted on a beam collector located directly under the air intake window. Sections of water distribution pallets with a perforated bottom are laid on the support grid, covering all the free space between the spillways. The sprinkler blocks are installed on pallets only in the middle part at equal distances from each spillway parallel to the rows of ejection nodes. The water distribution pallet consists of separate sections installed close to each other. Rows of holes are made in the bottom of each section.

EFFECT: increase in the cooling capacity of ejection cooling towers.
