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

Abstract

The invention relates to a downward spraying type spray boosting aeration cooling tower and shooting flow air-cooler. A tower body is provided with an out revolving type spray boosting wind pumping device inside which sprays frog flow by being connected pressure hot water, a nozzle downward sprays and laminas downward pump wind; cooling medium wind enters a wind channel for one time and two times from the tower top and a wind outlet is arranged on the middle lower part of the tower wall and is provided with a wind bucket. The lower part of the spraying device is provided with layers of drenching screen stencils, the water distribution and wind leading enable the drenching even and the cold winter passes amongst the water frog flow for a plurality of times, thereby greatly elevating the heat passing efficiency. Because the wind has the same direction with the water, the disturbance of the water frog to the laminas is reduced and the wind force of the ejection flow is increased, and the praying flow injection wind is downward and also be utilized, namely the generated three air flows of lamina mechanical wind, spray injection wind and the lamina injection wind proceed the heat exchanging with the spray flow, the wind rate is increased, the gas and water rate reaches above 1.0 which is 29 to 90 percent higher than the prior upward spraying cooling towers, and the reducing temperature can be greatly elevated. The noise of the tower water flow is reduced; the tower top has no drift ice, and the working hydraulic pressure is 0.08 to 0.12MPa. Because the wind temperature is near to the water temperature, the invention can be simultaneously used as the injection flow air-cooler, and the refrigerating air-condition in winter, 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...
