Novel eight-claw cooling tower

Abstract

The invention discloses a novel eight-claw cooling tower. The novel eight-claw cooling tower comprises a tower body, an air inlet, an exhaust window, a first wet and hot steam outlet, a second wet and hot steam outlet, a first negative pressure frequency conversion fan, a second negative pressure frequency conversion fan, an air inducing barrel, a vertical shaft pipeline, a pressure pipeline, a first spray nozzle, a water pool, a raw water source pipeline, a water feeding pipeline, a second spray nozzle, a deep well pump and the like. Compared with the prior art, the novel eight-claw cooling tower has the advantages that: 1) no wet and hot steam is discharged; 2) the temperature of circulating water is reduced and the cooling efficiency of the cooling tower is improved by changing the dry and wet bulb temperature of the air inlet of the cooling tower and increasing the air inlet amount through spray cooling in summer; and (3) in winter, by means of cold air and temperature change difference, the air inlet amount of the air inlet of the cooling tower is automatically controlled through an automatic spray icing air adjusting device, and the day and night cooling water temperature is controlled within the best vacuum range of a condenser under the condition that it is ensured that a water spraying area in cold weather is not iced no matter how the natural temperature changes.

Description

technical field [0001] The invention relates to the improvement of cooling efficiency and zero discharge of hot and humid steam of a cooling tower of a power plant, in particular to a novel eight-claw cooling tower. Background technique [0002] The cooling tower is an important heat transfer and mass transfer equipment in the process of generating electricity in a power plant. The earliest reinforced concrete cooling tower in the world was proposed by a scholar of the Netherlands Ministry of Mines at that time. After unremitting efforts in 1918, the hyperbolic rotating thin-shell cooling tower proposed by him finally became a reality. Britain was the first to use this cooling tower. Since the 1930s, it has been widely used in various countries. In the 1940s, hyperbolic cooling tower groups were successively built in Fushun Power Plant and Fuxin Power Plant in Northeast China. for a century. The structure and heat exchange mode of the cooling tower have not been substanti...
