Embodiment Construction

[0013] The present invention adopts the following structure: a device and method for alleviating high dam flood discharge atomization, including a control room (1), a connecting pipe (2), and a spray pipe (3). The control room contains power system, air supply pipeline, air pressure system, feeding device, etc. The connecting pipe (2) leads from the control room (1) and is arranged on the top of the side wall of the pad pond downstream of the dam, and the connecting pipe (2) is provided with spray pipes (3) at intervals. The opening of the injection pipe (3) is towards the inner side of the river bed, and the angle is adjusted to the height of the dense fog area of ​​the corresponding position.

[0014] The process of using this device to reduce high dam flood discharge atomization is as follows: In the control room (1), the feeding device adds environmentally friendly hygroscopic particles, and then passes through the connecting pipe (2) and sprays from the injection pipe (3)...

Abstract

The invention relates to a device and a method for alleviating flood discharging atomization of a high dam. The device comprises control rooms, connecting pipes, injection pipes and a low cost environmentally-friendly moisture absorption particle material. Injection systems are arranged at the top of a side wall of a downstream plunge pool of the dam or in a proper position of a downstream bank slope; the control rooms are close to the downstream face of the dam; the connecting pipes are arranged along the side wall top of the plunge pool and the injection pipes are arranged on the connecting pipes at intervals; the nozzles of the injection pipes face the inside of the plunge pool and the angles of the injection pipes can be adjusted toward a dense fog region. The environmentally-friendly moisture absorption particle material is injected to two sides of the dense fog region in the plunge pool by virtue of the injection devices. Atomized water drops are accelerated to combine and fall by virtue of the hydrophilicity of the moisture absorption particles and heavy rainfall is constrained in the plunge pool, so that the downstream atomizing damage is alleviated and the cost of a fog rain protective project is lowered, and meanwhile, a sufficient space is provided for optimizing project layout. The device and method not only can be used for a newly built high dam project, but also can be used for fog-reducing transformation of built projects.

Description

technical field [0001] The invention relates to the field of high dam flood discharge in water conservancy projects, in particular to a device and method for alleviating high dam flood discharge atomization. Background technique [0002] When water conservancy projects (especially high dam projects) discharge floods, large-scale rainfall and fog flow often appear in the downstream local area, which is called flood discharge atomization in the engineering field. The rainfall intensity caused by flood discharge atomization far exceeds the rain intensity value of extreme heavy rain in nature, which may cause great harm to the normal operation of water conservancy projects, traffic safety, surrounding environment and even the stability of downstream bank slopes. With the development of my country's hydropower industry, especially the implementation of the western development strategy, more and more high-head, large-discharge, and high-power reservoirs are built in narrow river v...
