Lower jet type spraying thrust aerating and cooling tower, and jet flow cool wind machine

Abstract

Downspray spray push draft cooling towers and jet coolers. The tower body is equipped with an external rotating spray propulsion and exhaust device that injects hot water under pressure and sprays mist flow. The nozzle sprays downward and the blades draw air downward; The middle and lower part of the tower wall is equipped with wind buckets. There is a multi-layer water spray screen under the spray device, which distributes water and guides the wind to make the water spray evenly, and the cold air passes through the water mist flow for multiple times to fully exchange heat, which greatly improves the heat transfer efficiency. Because the wind and water are in the same direction, the interference of water mist on the wind blades is reduced, the force of the jet flow is increased, and the downward direction of the spray flow ejection wind can also be used, that is, the three airflows of the wind blade mechanical wind, the spray ejection wind and the fan ejection wind are generated. Heat exchange with the spray flow, the air volume is increased, the air-water ratio is above 1.0, which is 29-90% higher than the existing spray cooling tower, and the temperature drop can be greatly improved. The noise of the water flow in the tower is reduced; the top of the tower does not float; the working water pressure drop is 0.08-0.12MPa. Because the outlet air temperature is similar to the outlet water temperature, it can be used as a jet cooler at the same time for cooling and air conditioning in spring, summer and autumn.

Description

(1) Technical field: [0001] The invention relates to a spray propulsion ventilation cooling tower and a cooling fan. The cooling tower uses the air in it as the cooling medium, and uses low-pressure hydraulic power to drive the spray to push the atomization device to realize the cooling of the circulating hot water. The cooling fan uses the circulating cold water in the atomization device through the spray as the medium to realize the cooling of the air. All belong to the heat exchange equipment category (F28C) where the medium directly contacts without chemical reaction. (two) background technology: [0002] The cooling tower is a device that uses hot water and cold air for heat exchange, so that the air is heated and humidified to take away heat and cool the circulating water. The cooling effect depends on the following three factors: ①The air volume of the cooling tower, that is, the air-to-water ratio. ②Mass transfer coefficient, area and time between gas and water. ③...
