Abstract
The invention relates to methods and devices for directing the flow of air in the suction area formed by the chamber below air-cooled condenser systems that are mounted on support structures and are comprised of air-cooled condensation installations consisting mainly of one vertical plane with air flowing through and of a plane consisting of condenser modules with cooling elements, designed for cooling process and turbine exhaust. In order to prevent the disrupting influences caused by crosswinds, according to the invention, wind deflection panels can be installed in the area of the air intake nozzles and/or near the floor underneath the air-cooled condenser system. The wind deflection panels according to the invention can be installed such that they are static or movable, made of steel construction, or made of other suitable materials, such as canvas, plastic, or wood. If the wind deflection panels are movable, an automatic or manual adjustment to current wind conditions is possible. Advantageously, such wind deflection panels are made of sound-absorbing materials.
Description
Technical field
The present invention relates to an a kind of method and a device, the water conservancy diversion that is used for air intake district air, the space of air intake district below the air setting equipment that is in above the supporting structure constitutes, air setting equipment is that flow through by perpendicular to be formed with condensation that utilize cooling element to be arranged on the plane basically, preferably is used for cooling procedure waste gas and turbine exhaust gas in the top cap type structure.Cooling element also can be provided with on the plane.
Background technology
The air setting equipment of cooling turbine waste gas or process waste gas generally is made up of assembly of the same type, and they are divided into many rows basically and are set in parallel on the plane of tessellate with front and back side by side.Increase on the supporting structure spare in formation air intake district on the general space in its lower section of this equipment.Each assembly has ventilating fan, the cooling air that its suction is flow through below supporting structure, and perpendicular was carried cooling element.For operate as normal, all ventilating fans should be carried identical air quantity, to keep basic condensation efficiency.Assembly is arranged on the supporting structure so for this reason, make its as much as possible each face can both flow into uniform cooling air.
When crosswind, air preferentially flows through condensing plant from a direction, and the field of flow in the air intake district below the interference assembly.Therefore, need to pay close attention to the minimizing of the cooling air volume that can cause the condensation efficiency reduction in the equipment component.Experience shows, particularly is in the outside, and is unfavorable especially near the assembly of wind, because occur the maximum fluidity speed of cooling air here.Its consequence is that aerial condenser usually no longer can guarantee the vacuum pressure that the turbine outlet upward requires, and causes the power plant energy loss.Under disadvantageous condition, improve exhaust gas pressure like this, to such an extent as to have to adopt the way of emergency shutdown for the protection turbine.No matter lowering efficiency or the power plant dead halt, all is unacceptable concerning the operator.
For avoiding this problem, be known in the prior art condensing plant around or the outside adopt the fence of windbreak, partition wall or fine mesh.Their effect is the wind that flows through of blocking-up, and below condensation the glitch-free air field of flow of formation.The shortcoming of these solutions is flow resistances that cost is high and increased the cooling air, and this resistance has only the energy consumption by improving the cooling, air discharging fan to compensate.In addition, in many cases, local particularity does not allow condensing plant is reconstructed.
Summary of the invention
The objective of the invention is to, avoiding under the described shortcoming situation, eliminate or reduce at least to a great extent the negative influence of crosswind.This purpose is achieved thus according to the present invention, promptly in the space in formation air intake district dividing plate is installed below the condensing plant on be in supporting structure.As dividing plate, can use the wall that is used for water conservancy diversion, promptly so-called windbreak.
Description of drawings
Fig. 1 illustrates air setting equipment, and the four row's condensers that had six condenser units by every row are formed the preferred implementation of windbreak shown in it.
The specific embodiment
In this regard, wall " A " and " B " are arranged in suspension type on the height of ventilating fan-air inlet on assembly row's the whole length or width, and wherein, the degree of depth of this windbreak blocking-up air stream depends on the quantity of its rear module.Compare with the free height below the steel construction piece, under " A " situation the height of windbreak blocking-up between 1/ (N-1) and 1/N, the quantity of the continuous assembly of wherein " N "=on wind direction.Under six or situation more than six assemblies, under the situation as windbreak " B ", 1/ (N-2) brought up in blocking-up.
Relevant with the ventilating fan of outside, wall " A " and " B " make the air accumulation of gushing below the ventilating fan cooling air inlet, and therefore improve the supply of air.Thus in mode even can utilize the kinergety that contains in the wind with advantage.Test shows that unexpectedly the optimization setting of windbreak can not produce the extra pressure loss of ventilating fan, but opposite, guarantee assembly by trend improve supply.Because windbreak is the cross section part of blocking-up cooling air stream only almost, just be equivalent to share the cooling air stream part on the assembly, do not have or only be subjected to slight influence so be in the assembly of blocking-up wall back.
Another preferred embodiment in, on the bottom than low height on another windbreak " C " is installed, the assembly that it can guarantee directly to be in upper isolation wall " A " and " B " back is air supply better.The height that is installed near this windbreak " C " in bottom is preferably the 1/N of supporting structure spare free height, maximum 1/4.Preferred distance from bottom is about 1m, still, and on the corresponding apparatus specification, for service equipment more simply can be brought up to about 2m.The rising component that this bottom wall " C " gives to flow below assembly cooling air has advantage.Use this windbreak to depend on local situation, particularly predominant wind near the bottom.
Windbreak " A ", " B " and " C " can be steel construction piece, but other materials also can be suitable for, as canvas, plastics or timber structure.These walls can be mounted to state type or movable, for example in the mode of rolling screen door or shutter.The movable installation of windbreak can match with wind regime at that time, particularly wind direction and wind speed.The wind regime conformability of this movable wall can be finished automatically or manually.What have advantage is that foundation windbreak of the present invention can constitute with sound insulating material, can further reduce the noise of air setting equipment thus.
Tool is advantageous to be, not only can be set directly at newly-built sky according to windbreak of the present invention On the solidifying equipment of air cooling, and can follow-uply be installed on the existing condensing plant.
