A water distribution partition device in a natural ventilation wet cooling tower

Abstract

The invention provides a natural ventilation wet cooling tower internal water distribution partition device. A water pool is disposed at the bottom of a cooling tower; a middle partition wall is disposed at the bottom of the water pool and divides the water pool into two equal portions; the cooling tower comprises an inner surrounding water distribution area and a peripheral water distribution area; a water distribution vertical shaft is disposed in the cooling tower; and four two-layer water distribution grooves are formed in the water distribution vertical shaft. Each two-layer water distribution groove comprises an upper-layer water distribution groove body and a lower-layer water distribution groove body,wherein an installation groove is formed in the outer side of the shaft wall of the water distribution vertical shaft; an upper-layer gate which is matched with a water inlet of the upper-layer water distribution groove body is disposed in the installation groove; the lower-layer water distribution groove body comprises two outer-region water distribution groove bodies; lower-layer water inlets which coincide with water inlets of the outer-region water distribution groove bodies are formed in the inner wall of the water distribution vertical shaft; and the water inlet of each outer-region water distribution groove body is provided with a lower-layer gate correspondingly, and the lower-layer gates of each two-layer water distribution groove are arranged side by side and located at the same height. By means of the technical scheme, the good cooling effect of the cooling tower can be guaranteed, installation and maintenance of the gates are convenient, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of cooling towers, in particular to a water distribution division device in a natural ventilation wet cooling tower. Background technique [0002] Natural ventilation wet cooling towers have been very maturely used in power plants. The water distribution shaft of the cooling tower is supplied by a circulating water pump. Usually, one unit is equipped with one natural ventilation cooling tower. The operation and maintenance of the cooling tower is more convenient. However, in some engineering projects, due to the limitation of the factory area, the scheme of one cooling tower for one unit cannot be realized, so the scheme of two cooling towers for one cooling tower came into being. The scheme of two machines and one tower needs to consider that when the mud accumulation in half of the cooling tower pool needs to be cleaned, it is necessary to shut down the corresponding half of the cooling tower water distrib...

AI Technical Summary

Problems solved by technology

On the one hand, since the cooling tower is divided into multiple partitions by the single-layer water distribution tank and the double-layer water distribution tank, when the whole tower is running, it is difficult to achieve the same flow distribution between the single-layer water tank and the double-layer water tank, resulting in uneven water distribution. This makes the cooling effect of the cooling tower not good; in addition, there are multiple gates and opening and closing devices for driving the gates in the water distribution shaft, and the gates of the double-layer water distribution tank need to be arranged up and down along the height direction of the water distribution shaft, resulting in gates And the installation and maintenance of the opening and closing device is inconvenient, and the upper and lower gates are installed in the shaft at the same time, occupying the flow area of ​​the water distribution shaft, increasing the hydraulic loss, and thus increasing the power consumption of the circulating water pump
