Novel cooling tower turntable and matched system thereof

Abstract

The invention relates to a novel cooling tower turntable. The turntable is characterized in that the turntable comprises a rotating shaft; n blade parts are arranged along the axial direction of therotating shaft; each blade part comprises a regular polygon blade or each blade mechanism comprises a triangular blade group consisting of a regular polygon blade and M triangular blades; the regularpolygon blades are arranged on the rotating shaft in a penetrating mode, and when the blade parts further comprise triangular blades, the M triangular blades in each blade part are symmetrically and circumferentially distributed with the main shaft as the circle center. A channel is formed between two adjacent regular polygon blades or between the adjacent regular polygon blades and the triangularblades. Another technical scheme of the invention is to provide an auxiliary water spraying system. The innovative points of the invention are as follows: the blades on the rotating shaft are a combination of regular polygons and triangles or a single regular polygon, and the regular polygon can be formed by cutting a thin plate or splicing a plurality of thin plates. The blade structure can greatly reduce the production process difficulty and the manufacturing cost.

Description

technical field [0001] The invention relates to a turntable used in an open cooling tower (especially a turntable type thin-film evaporation cooling tower), and also relates to a matching inlet and return water system for a cooling tower using the turntable. Background technique [0002] The working principle of the traditional open cooling tower is: use the wind blowing in to form convection with the water sprinkled from above, the surface of the water in contact with the wind evaporates, and the wind takes away the corresponding latent heat of evaporation, thereby reducing the temperature of the water . Part of the water will be evaporated and taken away by the wind. The evaporation is the part necessary for the cooling water and air to dissipate heat. Generally, it is about 0.8% of the total circulating water. Of course, this value is related to the cooling degree of the circulating water and other parameters. In addition to the amount of evaporation, the water loss of t...
