Embodiment 1

[0017] Example 1: see figure 1 , image 3 , Figure 4

[0018] See figure 1 , The downspray spray propulsion ventilation cooling tower is composed as follows: the top of the tower body 6 is provided with a primary air inlet tube 2 where a primary air inlet 2a is formed; the outer periphery is provided with a secondary air inlet tube 3 where a secondary air inlet 3a is formed. The side wall of the middle and lower part of the tower body is fully opened with an air outlet, where an air bucket 9 with a water accumulation function is installed to form an air outlet 9a. When the tower body is a tetrahedron, the wind bucket is a four-sided inverted trapezoid; when the tower body is a cylinder, the wind bucket is an inverted cone. The area of ​​the air outlet 9a is greater than the sum of the areas of the air inlets 2a and 3a. The tower body 6 is welded together by a plurality of supporting steel pipes or water pipes, the tower wall is formed by sealing the tower plate 6.1, an...

Embodiment 2

[0025] Example 2: Jet Cooler

[0026] See figure 2 , except that the structure of the downspray spray propelling ventilation cooling tower of embodiment 1 is all the same except for the following, the difference: 1. if the tower body 9 is a square, the area of ​​the air outlet is 1 / of the area of ​​the fully opened air outlet on the side wall of the tower body 4. That is, the three sides of the tower wall are sealed, and only one side is equipped with a wind bucket 9 . 2. install the air delivery pipe 13 on the air funnel. ③The water inlet pipe 7 is refrigerant water (7-20° C.), the air intake is hot and humid wind, and the air outlet is cold and wet wind. The raised hot water is in the sump tank and the water outlet pipe.

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...
