Abstract

The invention discloses a mixed flow type spraying propulsion air cooling tower. The inside of the tower is provided with a spraying propulsion atomization plant, a jet current catch pan, a water pipe and a screen stencil drogues from top to bottom; the screen stencil drogues is outside provided with a watering sieve plate and a watering screen stencil; the end of the inflow pipe is provided with a solid-liquid separator for separating the impurities, and the top thereof is provided with a swirl nozzle. The atomization plant is inner provided with a bottom spraying rotary atomizer and the bottom inducing draft rotating paddles, which produces spray and impels the paddles to rotate, and synchronously forms fan blade mechanical air and jet flow inducing draft to cool the heat water. As the flow of the paddles is in the same stream with the spray flow, the wind pressure is reduced; therefore the cooling air flow is greatly increased. The spray flow is collected in the jet current catch pan, and then is distributed as exiguous drops to fall down via the watering sieve plate and the watering screen stencil, while the inlet air comes in from the tower top and heat transfers with the water drops by a screen stencil air passage located at the middle part of the tower via the three ways of following current, cross current and adverse current to take the heat off. No vortex cavities and short flows are in the tower. The invention has the advantages of big air flow, sufficient mass transfer, good temperature drop, simple structure, high reliability, and low noise, which can be used for cooling sewage.

Description

(1) Technical field: [0001] The invention is a novel cooling tower. The cooling tower uses the air in it as the cooling medium, and uses low-pressure hydraulic power to drive the spray to propel the atomization device to carry out spray draft and nozzle spray, so as to realize the cooling of circulating hot water. It belongs to the heat exchange equipment category (F28C) in which the medium directly contacts without chemical reaction. (two) background technology: [0002] Existing cooling towers include power ventilation packing towers, spray ventilation cooling towers and natural ventilation hyperbolic cooling towers. No matter which type, the cooling principle is: use cold air and hot water for heat exchange, so that the air heat increases. Humidity removes heat and cools hot water. According to this principle, cooling tower cooling satisfies the following heat balance equation: [0003] Cw(tw1-tw2)=λ[r(X 2 -X 1 )+C P (ta2-ta1)〕 [0004] Or Δtw=λ(600Δx+0.24Δta) (1) ...
