Abstract

The invention discloses an optimized arrangement method of a horizontal rigid ring of a natural ventilating cooling tower. The optimized arrangement method comprises the following steps that: wind load basic information of a cooling tower is input, so that the distribution situation of the wind load along the height and horizontal directions of the cooling tower is obtained; iterative analysis for multiple times is carried out on the input wind load basic information of the cooling tower, so that the reasonable optimized arrangement of the horizontal rigid ring is obtained; and the optimized design of the height and width dimensions of the rigid ring is carried out according to the confirmed arrangement, so that the most optimized arrangement and design scheme of a horizontal reinforcing ring can be obtained. According to the invention, aiming at the set cooling tower structure, and through the optimized arrangement on the position, number and dimension of the horizontal rigid ring of the cooling tower, the maximal stable coefficient of the cooling tower can be obtained further, also the wall thickness of the cooling tower can be reduced, and the integral investment is saved.

Description

technical field [0001] The invention relates to the technical field of manufacturing cooling towers, in particular to design a method for optimally arranging horizontal rigid rings of natural draft cooling towers. Background technique [0002] Existing natural draft cooling tower is made up of two parts of tower tube and shower device. The tower is composed of a reinforced concrete hyperbolic rotary thin-shell ventilator, inclined pillars and a foundation with a water storage tank wall. In order to reduce the input cost of the cooling tower, designers make the cooling tower higher and higher and the shell thinner and thinner, which will greatly reduce the stability of the cooling tower. In order to increase the stability of the cooling tower and reduce the input cost of the cooling tower, countries such as West Germany have proposed the use of additional horizontal rigid rings to obtain the maximum buckling coefficient. At present, natural draft cooling towers designed at ...
