Problems solved by technology

The high water density in the rain area increases the ventilation resistance of the cooling tower, and it is difficult for the cold air from the outside to enter the center of the tower, resulting in a decrease in the uniformity of the flow field in the tower, reducing the ventilation volume of the cooling tower, and reducing the heat transfer in the rain area. Quality and performance
The deterioration of the ventilation performance in the rain zone directly affects the ventilation characteristics of th

Abstract

The invention discloses a rain-area dry and wet mixed cooling system with internal and external coordination of a natural draft wet cooling tower. The rain-area dry and wet mixed cooling system comprises the natural draft wet cooling tower, and a plurality of flow distribution plates are arranged in the rain area of the natural draft wet cooling tower. Each flow distribution plate is of a plate-shape structure, one end of the flow distribution plate is connected onto a tower wall of the natural draft wet cooling tower, and the other end of the flow distribution plate points to the adjacent flow distribution plate. The two sides of each flow distribution plate are arranged obliquely, and one side, close to the tower wall of the cooling tower, of the flow distribution plate is lower than theother side of the flow distribution plate. All the flow distribution plates show rotational symmetry about the center of the radial section of the super large wet cooling tower. The part of the rainarea covered by one flow distribution plate forms a dry area, and an air inlet in the bottom of the natural draft wet cooling tower is divided into a plurality of dry area inlets and a plurality of rain area inlets by a plurality of dry areas. Air deflectors are vertically arranged on the two sides of the ground of each dry area inlet, and the air deflectors are arranged on the outer side of the tower wall.

Description

technical field [0001] The invention relates to the field of energy and power engineering, in particular to a novel natural ventilation wet cooling tower which coordinates and optimizes the air intake inside and outside. Background technique [0002] The statements herein merely provide background information related to the present invention and may not necessarily constitute prior art. [0003] The internal area of ​​a conventional wet cooling tower is generally divided into a water distribution area, a fill area, and a rain area. The high water density in the rain area increases the ventilation resistance of the cooling tower, and it is difficult for the cold air from the outside to enter the center of the tower, resulting in a decrease in the uniformity of the flow field in the tower, reducing the ventilation volume of the cooling tower, and reducing the heat transfer in the rain area. qualitative performance. The deterioration of the ventilation performance of the rain...
