Definitions
- the present invention relates to a method and a belonging to a condenser device for flow guidance of air in the intake formed from the space below standing on supporting structures air-cooled condenser systems consisting of substantially vertically flowed and arranged substantially on one level condensation modules with cooling elements preferably in roof design Cooling of process and turbine exhaust.
- the cooling elements can also be arranged flat.
- Air-cooled condenser systems for cooling turbine or process vapors usually consist of similar modules which are arranged in several rows parallel next to each other and behind each other substantially in a plane in the form of a chess board. These systems are usually elevated on a support structure forming a suction area in the space below it. Each module is provided with a fan which draws in the cooling air flowing under the support structure and conveys it substantially vertically through the cooling elements. For undisturbed operation, all fans should deliver equal volumes of air to maintain the underlying condensation performance. For this purpose, the modules are on a support structure that, if possible, a uniform inflow of cooling air is possible from all sides.
- the object of the invention is, while avoiding the disadvantages listed above, to eliminate or at least substantially minimize the negative effect of crosswind, so that in the case of an existing air flow which is exposed to a lateral wind action, the cooling generated by the existing air flow does not decrease so much let the cooling capacity fall below a critical value.
- baffles are installed in the space forming a suction area below the condenser system standing on support structures.
- baffles walls for flow guidance so-called wind deflectors, can be used.
- Fig. 1 shows an air-cooled condenser system consisting of four rows of capacitors, each with six capacitor units, in which a preferred embodiment of the wind deflector is located.
- the walls "A” and “B” are arranged hanging at the level of the fan inlet nozzles over the entire length or width of the rows of modules, wherein the air flow blocking depth of these wind deflectors of the number of underlying modules depends.
- the obstruction increases to 11 (N - 2).
- the walls "A" and “B” cause damming of the incoming air below the cooling air inlet of the fans and thus a better supply of air.
- this even uses the kinetic energy contained in the wind.
- experiments have shown that the optimized arrangement of the wind deflectors produces no additional pressure loss for the fans, but on the contrary ensures a tendency to better supply the modules. Since the wind deflectors block approximately only the cross-sectional portion of the cooling air flow corresponds to the proportion of attributable to the modules cooling air flow, the modules located behind the barrier walls are not or only slightly influenced.
- further wind deflectors "C” are drawn in at a low height above the ground, which ensures better air admission of the modules located immediately behind the upper partitions "A" and "B".
- the height of this set up near the bottom wind deflector “C” is preferably 1 / N, maximum 1 ⁇ 4 of the clear height of the support structure.
- the preferred ground clearance is about 1 m, but can also be increased to about 2 m with a corresponding size of the plant for easier inspection of the system.
- These bottom walls "C” provide an advantageous upward component to the cooling air flowing under the modules.
- the use of such ground-level wind deflectors depends on the local conditions, in particular the main wind direction.
- the wind deflectors "A”, “B” and “C” can be made in steel construction, but other materials such as canvas, plastics or wooden structures are suitable for use.
- the walls can be static or movable z. B. be installed in the form of roller shutters or blinds.
- the movable attachment of the wind deflectors allows adaptation to the particular wind situation, especially the wind direction and the wind speed.
- the Adaptation of such movable walls can be done automatically or manually.
- the wind deflectors according to the invention can be carried out in sound-insulating materials, whereby the noise emission of the air-cooled condenser system can be further reduced.
- the wind deflectors according to the invention can be integrated not only in new constructions of air-cooled condenser systems but retrofitting of existing condenser systems is possible.
