Embodiment Construction

[0018] As shown in the figure, the cooling process of the cooling tower is to spray the hot water 19 on the water spray filler 21 by the nozzle 13 to form large and small water droplets or a very thin water film, which contacts with the rising air 20 . The heat in the hot water 19 is transferred to the air 20 due to the temperature difference, and the water is vaporized and evaporated. The air 20 takes away the heat required for gasification and the water vapor 12 produced by the gasification due to the suction force of the fan 4, and the water that loses heat falls into the sump 3 after reducing its temperature. The air 20 and water vapor 12 form saturated hot and humid air, which continues to rise with the suction of the fan 4, passes through the water eliminator 22, removes the fine water droplets mixed in the hot and humid air, and discharges out of the tower from the air duct.

[0019] The condensation process of the cooling tower is that the water pump 1 uses the cold wa...

Abstract

This invention relates to a method for decreasing water evaporation loss in cooling tower and its operation method. The method is to use water as condensate in cooling tower, and cool water vapor to water. The mode of operating this method is to produce the hollow-shaped slingshot through the automatic condensate device in cooling tower, and the slingshot spouts the condensate to the slender drip to connect it with the water vapor, which makes it become water when meeting cold. The condensate doesn't connect with the hot that is at cooling process when it descends, but it drops in the collecting-tank directly along the cooling tower wall. The heat that is passed in the cooling course and condensing course is sent out by fan. Working out the wet containing value according to the humidity transformer that is arranged on the top of the cooling tower fan, comparing it with the enacted wet containing value through the transmitter and the control to get the measured warp, and sending out the control signal according to a certain rule, adjusting the shower density of the thrower to achieve the automatic condensation process.

Description

technical field [0001] The invention relates to cooling tower technology, in particular to a method for reducing water evaporation loss in a cooling tower, and to a device for realizing the method. It belongs to the technical field of international patent classification F28C1 / 00 "cooling tower". Background technique [0002] The cooling tower refers to spraying hot water on the water-sprinkling filler in the tower to form water droplets or water films, and conducts convective heat transfer from top to bottom with the cold air with heat-absorbing ability flowing from bottom to top, and uses the evaporation and diffusion of water It acts as a cooling device that removes heat from water. This cooling equipment is mainly a wet cooling tower. Wet cooling towers are mainly in the form of draft counterflow cooling towers. The present invention is exactly the water-saving method designed for this type of cooling tower. [0003] When designing a cooling tower, in order to reduce ...
