Hyperbolic natural ventilation cooling tower with cold condensation liquid concentration demisting function

Abstract

The invention discloses a hyperbolic natural ventilation cooling tower with a cold condensation liquid concentration demisting function. The tower comprises a hyperbolic tower body, a natural coolingair inlet and a water distribution device, wherein the natural cooling air inlet is formed in the side surface of the lower section of the hyperbolic tower; an air cooling condensation water collecting device is arranged above the water distribution device; a cold air pumping and supplying device is arranged outside the hyperbolic tower body; a low-temperature cooling air source is provided by thecold air pumping and supplying device for the air cooling condensation water collecting device; low-temperature air is input into a hollow heat conduction shell and then is discharged into the innercavity of a tower neck after sufficient heat exchange, therefore, the temperature of the hollow heat conduction shell is always close to the outside temperature, and water drops can be quickly condensed when high-temperature saturated water vapor meets the low-temperature hollow heat conduction shell so as to form clean water. The hyperbolic natural ventilation cooling tower with the cold condensation liquid concentration demisting function is simple in structure, capable of eliminating mist and saving water, energy-saving and environment-friendly, and capable of obtaining pure fresh water, the natural drainage performance of a cooling tower is improved, the drainage pressure is increased, the ventilation resistance is reduced, and the cooling effect is improved.

Description

Technical field: [0001] The invention relates to an industrial cooling tower, in particular to the technology of defogging and water vapor recycling of the cooling tower of a power plant. Background technique: [0002] At present, there is no successful application-level achievement in the water vapor recovery technology of the hyperbolic natural ventilation cooling tower of the power plant. A water-saving device for the cooling tower of the power plant is disclosed in the Chinese patent ZL201020162612.8 "Water-saving device for the cooling tower of the power plant". A cooling hood is set directly above the top of the cooling tower to collect water vapor. The cooling hood condenses the water vapor emerging from the top of the cooling tower and falls into the tower for reuse. It can condense a small amount of water vapor discharged into the atmosphere Condensation of water vapor into condensed water for direct reuse; Since the cooling tower is a continuous working system, sat...

Problems solved by technology

Theoretically speaking, although this cooling tower water-saving system of a power plant can realize the recycling of water vapor and has the function of saving water, it is very unlikely to be popularized and applied in practice, and there is no actual use case at home and abroad. The reason is that The structure of the scheme is complicated, and the auxiliary equipment includes three small cooling towers, three water pumps, one air conditioner and one booster pump. The water consumption in the process is large, the operation power consumption is high, and the operation cost is high. At the same time, secondary water vapor fog pollution will also be generated. At the same time, the recovered steam water is accompanied by cooling spray water and hot water sprayed from the hot water inlet pipe. Falling into the water-sprinkling filler together, after secondary heating, secondary evaporation occurs, and the high-quality water recovered by the steam is not utilized, and the economic benefit is poor

In addition, the spraying device sprays pressurized cooling water mist and raindrops downward from the top of the cooling tower, which directly blocks the outflow of the mixed air from the upper part of the cooling tower, and the cooling air cannot be discharged continuously and smoothly, which will seriously affect the cooling of the cooling tower.
