Dehydrator for cooling tower

Abstract

The invention discloses a dehydrator for a cooling tower. The dehydrator for the cooling tower is characterized in that the dehydrator comprises multiple blades, bent channels allowing air flow to pass through are formed between adjacent blades, and each bent channel is of a variable section structure; the sectional area of the middle of each bent channel is smaller than that of the upper portion of the bent channel and that of the lower portion of the bent channel; further, the vertical section of each blade comprises a first linear section, a first arc curved section, a second linear section and a second arc curved section, wherein the first linear section, the first arc curved section, the second linear section and the second arc curved section are connected in sequence; each first linear section is located on an air flow inlet; the bending direction of each first arc curved section is opposite to that of the corresponding second arc curved section; the curvature of each first arc curved section is larger than that of the corresponding second arc curved section. According to the dehydrator for the cooling tower, the dehydration efficiency and the dehydration effect are improved fundamentally, so that water resources are saved, efficiency is high, and energy is saved.

Description

technical field [0001] The invention relates to a water eliminator, in particular to a water eliminator for a cooling tower. Background technique [0002] There are many cooling towers used in power plants, chemical plants, etc., and the cooling water consumption is huge. The water eliminator installed in the cooling tower is used to recover the small water droplets in the hot and humid air discharged from the cooling tower, and play a role in water retention. 1. The effect of preventing water from splashing everywhere. If there is no water eliminator, it will be like light rain next to the cooling tower. The evaporation and splashing of water will be serious, which will not only waste water resources, but also be environmentally friendly and affect the surrounding environment; Commonly used water eliminators include C-type, right-angle V-type, right-angle W-type, primary surface type and other structures. The principle is to use centrifugal force to make water droplets coll...

[0002] There are many cooling towers used in power plants, chemical plants, etc., and the cooling water consumption is huge. The water eliminator installed in the cooling tower is used to recover the small water droplets in the hot and humid air discharged from the cooling tower, and play a role in water retention. 1. The effect of preventing water from splashing everywhere. If there is no water eliminator, it will be like light rain next to the cooling tower. The evaporation and splashing of water will be serious, which will not only waste water resources, but also be environmentally friendly and affect the surrounding environment; Commonly used water eliminators include C-type, right-angle V-type, right-angle W-type, primary surface type and other structures. The principle is to use centrifugal force to make water droplets collide with the surface of the blade of the water eliminator, and the water flows down the surface of the blade to realize recovery and cooling. The purpose of water droplets in the humid air in the tower, the water eliminators of these structures in the prior art generally keep the cross-sectional area of ​​the wet air circulation channel unchanged, or the cross-sectional area of ​​the wet air inlet and outlet is small, The cross-sectional area of ​​the middle part is large, and the centrifugal force is not increased; on the other hand, the blades of the water eliminator adopt an ordinary smooth surface, and there is no reinforcement for water droplet adsorption and water film diversion; therefore, although the structure of the water eliminator in the prior art There are some differences, but there is no substantial improvement between them, and the water removal effect has not been greatly improved, and the way to improve the water removal efficiency is to simply stack multi-layer water eliminator structures, at the cost of increasing material costs and increased resistance to flow
