Abstract
The present invention relates to a kind of for mitigating the device and method of high dam flood-discharge atomizing, including control room, connecting tube, injection pipe and low-cost environment-friendly moisture absorption granular materials.The spraying system is arranged at the top of the abutment wall on the dam water cushion pool downstream pool or downstream bank slope appropriate location, and control room is arranged close to dam downstream face, connecting tube along cushion pool abutment wall top, arranged for interval injection pipe along pipe, and nozzle is to cushion pool inside, and adjustable angle is to thick fog area.Environment-friendly type moisture absorption particle is ejected into the thick fog area two sides in cushion pool by injection apparatus, utilize moisture absorption particle hydrophily, accelerate the combination and landing of water droplets, heavy rainfall is constrained in cushion pool, mitigate downstream atomizing harm, reduction fog precipitation protection works cost to reach, while optimizing to work arrangement and sufficient room is provided.The present apparatus and method can be not only used for newly-built high dam engineering, and can be used for built engineering subtracts mist transformation.
Description
Technical field
The present invention relates to the high dam flood discharge fields in hydraulic engineering, are specifically related to a kind of for mitigating high dam flood-discharge atomizing
Device and method.
Background technique
When hydraulic engineering (especially high dam engineering) flood discharge, often there is fairly large rainfall and mist in the regional area of downstream
Stream diffuses phenomenon, and engineering circles are referred to as flood-discharge atomizing.Rainfall intensity caused by flood-discharge atomizing is considerably beyond especially big sudden and violent in nature
The raininess value of rain may cause the stabilization of the normal operation of key water control project, traffic safety, ambient enviroment even downstream bank slope
Larger harm.It is more and more high water heads, big with the implementation of the development of China's hydropower, especially strategy to develop western regions
Discharge, high-power reservoir are built among Narrow Valleys.To solve the problems, such as that dissipation and scouring, flaring gate pier, narrow slit type choose bank, choose flowing water
The novel energy dissipation type of a batch of stock collision is earned widespread respect and is applied.It turns out that these energy dissipation types can obtain preferably
Effect of energy dissipation, but one of disadvantage is exactly that may cause more serious fogging problem.Previous hydraulic engineering is mostly by under reinforcing
Trip side slope (anchor cable and concrete paste slope) endangers to reduce atomization bring, these methods are complicated in the presence of construction, with high costs,
Waste the disadvantages of serious.If being allowed to and water droplets by spraying environment-friendly type moisture absorption granule materials to the thick fog area of flood-discharge atomizing
It is spread in conjunction with it to accelerate to fall, is limited to periphery, the effectiveness for mitigating flood-discharge atomizing degree can be played.There is presently no corresponding
System and equipment.
Summary of the invention
The object of the present invention is to provide one kind to mitigate high dam flood-discharge atomizing using low-cost environment-friendly moisture absorption granule materials
The device and method of degree.
Purpose of the present invention realization means: a kind of for mitigating the device of high dam flood-discharge atomizing, including control room (1), company
Take over (2), injection pipe (3).Control room includes dynamical system, steam line, air compression system, feeding device etc..
Connecting tube (2) is drawn from control room (1), is arranged in dam water cushion pool downstream side of a pond wall top portion, connecting tube is spaced on (2)
It is arranged injection pipe (3).
Injection pipe (3) is open on the inside of riverbed, the thick fog area elevation of angle tuning corresponding position.
It controls in room (1), feeding device adds environmentally friendly moisture absorption particle, passes through connecting tube (2) later, sprays from injection pipe (3)
Directive thick fog area.
The material is low-cost environment-friendly moisture absorption granule materials.
Totally two sets of the covering device, it is arranged in dam downstream two sides.It can be disposed at the top of the abutment wall of cushion pool, it can also be with
It is arranged in downstream bank slope appropriate location.
The present invention relates to for mitigating the device and method of high dam flood-discharge atomizing, by injection apparatus by moisture absorption particle
Material is ejected into cushion pool two sides thick fog area, by the hygroscopicity of environmentally friendly moisture absorption particle itself, accelerates combination, the drop of water droplets
It falls, heavy rainfall is constrained within the scope of cushion pool, mitigate the downstream atomizing degree of high dam, save traditional preventing atomization engineering cost,
More sufficient room is provided to engineering proposal layout optimization.Operation of the present invention is reliable, construction safety, conveniently, save the cost.

It manages (2) to draw from control room (1), is arranged in dam water cushion pool downstream side of a pond wall top portion, setting injection pipe in interval in connecting tube (2)
(3).Injection pipe (3) is open on the inside of riverbed, the thick fog area elevation of angle tuning corresponding position.
The process for mitigating high dam flood-discharge atomizing with the present apparatus is as follows: in control room (1), feeding device adds environmentally friendly moisture absorption
Grain passes through connecting tube (2) later, sprays from injection pipe (3) to thick fog area.By the hygroscopicity of environmentally friendly moisture absorption particle itself, add
Combination, the landing of fast water droplets, heavy rainfall is constrained within the scope of cushion pool, the downstream atomizing degree of high dam is mitigated, saves and passes
The preventing atomization engineering cost of system provides more sufficient room to engineering proposal layout optimization.
The material is low-cost environment-friendly moisture absorption granule materials.
Totally two sets of the covering device, it is arranged in dam downstream two sides.It can be disposed at the top of the abutment wall of cushion pool, it can also be with
It is arranged in downstream bank slope appropriate location.
Although specific embodiments of the present invention have been described above, however, it should be understood that above-mentioned implementation can not be depicted
The component of example or all possible combinations of method, each examples of implementation can do further combinations and permutations.Therefore, herein
Described in examples of implementation all such changes, modifications for being intended to cover to fall within scope of appended claims and
Modification.
