Definitions

  • the invention relates to an air-charged capacitor having the features in the preamble of patent claim 1.
  • the major disadvantage of known adiabatic cooling is the soaking of the cooling elements, supporting structures and other plant components that are located below the cooling elements.
  • the soaking of the cooling elements leads in the long term to an undesirable deposition of insoluble matter, while electrical components such as transformers must be fully protected against the ingress of moisture to avoid short circuits.
  • the exact dosage of water and the distribution of water is very difficult to calculate, since the distribution of Water droplet depends inter alia on the wind direction and the temperature distribution. An uneven distribution inevitably leads to a local wetting and thus to a drop formation, ie the water drips down on the capacitors and the support structure. This can cause unwanted corrosion even when using demineralized water.
  • the object of the invention is to improve an air-cooled condenser such that the condensation elements are not wetted by the means provided for adiabatic cooling of the cooling air and wherein the means for adiabatic cooling can also be retrofitted with little effort.
  • the core of the invention is that the means for adiabatic cooling can be charged with water to be evaporated contact body, which are arranged in the region of the cooling air flow, that is on the upstream side of the condensation elements.
  • the contact bodies have a large surface on which water introduced into the contact bodies can evaporate.
  • the water is at no time free within the cooling air flow, as is the case with spraying by means of nozzles.
  • spraying by means of nozzles.
  • there is virtually no need for excess water since the water taken up in the body of the contact is transferred exclusively by mass transfer, i. Evaporation, is transferred to the cooling air flow. This will also ensure that corrosion damage due to undesired moistening of nearby components, e.g. the fan, be avoided.
  • the air-charged condenser according to the invention is preferably provided for the condensation of water vapor.
  • these are condensers for condensing the exhaust steam flow from a turbine of a power plant.
  • the air-charged capacitors for the condensation of other substances, such as for the condensation of propane are provided.
  • the inventive concept is not limited to the condensation of water vapor.
  • the air-charged capacitor according to the invention is not limited to a specific type of capacitor.
  • the contact bodies which can be charged with water to be evaporated can be used in combination with A-shaped, V-shaped, vertically or horizontally arranged condensation elements. The use of such contact bodies in connection with A or roof-shaped condensation elements is considered to be particularly favorable.
  • the contact body may be arranged in a first embodiment in the intake of the condensing elements upstream fan, ie it is located in the flow direction in front of the fan.
  • Contact bodies can be mounted, for example, in conjunction with a protective grid, which is mounted in front of the fans.
  • contact bodies can also be arranged in the outlet region of the cooling air flow out of the fan, ie behind the fan in the cooling air flow direction.
  • a further variant provides that contact bodies are arranged directly in front of the condensation elements and cover at least part of the inflow surface of the condensation elements.
  • the contact body can cover the entire inflow of the condensation elements or even a partial area. It is conceivable that e.g. only some of the condensation elements are provided with contact bodies, others, however, not. Partial coverage of the condensation elements may be e.g. in the upper, middle or lower third. The respective degree of coverage and the exact positioning of the contact bodies must be made dependent on the local conditions. Here can not be called a rigid rule.
  • the degree of coverage of the inflow surface is adjustable by displacement of the contact body.
  • the contact bodies are inactivated, i. that no prehumidification of the cooling air is desired, these could e.g. be pivoted and taken in a certain way out of the cooling air flow, so that a larger inflow of the condensation elements is released for pure dry cooling.
  • the swinging out also has the advantage that no additional pressure loss caused by the contact body.
  • the axis about which the contact bodies are pivoted depends on the spatial conditions.
  • the pivot axis may extend in the ridge region, that is to say essentially horizontally, but at least in parallel to those of the condenser elements. condensation elements spanned levels. It is also conceivable that the pivot axis is not horizontal, but runs parallel to the planes spanned by the condensation elements, that is to say in the case of condensation elements arranged in an A-shape, in accordance with the inclination of the condensation elements. If the spatial conditions permit, the contact bodies can also be arranged to be translationally displaceable.
  • contact bodies are fastened directly to the condensation elements on their sides facing the fan.
  • the contact bodies may e.g. be attached to the end faces of the transversely ribbed tubes of the condensation elements.
  • the attachment of contact bodies directly to the condensation elements only leads to a negligible increase in the flow resistance, so that no pressure losses occur. Nevertheless, the contact bodies are completely within the cooling air flow.
  • contact bodies fastened directly to the condensation elements can be provided only in partial areas. For example, every second tube of the condensation elements could be provided with contact bodies.
  • the contact bodies are preferably a fleece, a fabric or a porous plastic.
  • the essential characteristics of having suitable contact bodies are high storage capacity for water and a large surface area to allow rapid evaporation of the water.
  • the material used should have sufficient air permeability, depending on the arrangement within the cooling air flow, in order to limit the pressure losses.
  • Self-supporting materials are considered to be particularly advantageous, and combined multi-layer materials may be used, wherein one position of the contact body fulfills the support function and at least one other layer is designed specifically for water absorption and high evaporation.
  • Common and inexpensive available on the market are geotextiles or Nonwovens that provide the desired absorbency and good evaporation of water.
  • the materials mentioned have a high resistance to aging and are also mechanically sufficiently resistant.
  • the contact bodies can preferably be cleaned after a predetermined period of use and then reused.
  • the contact body should therefore not decompose under the influence of air and water.
  • By a suitable choice of material both a high mechanical strength and at the same time a corresponding desired water absorption capacity can be achieved. Both are prerequisites for use within the cooling air flow in air-cooled condensers.
  • the contact bodies are preferably formed as flat plates.
  • one-piece or multi-layer contact bodies deviate in their geometry from flat plates, ie, for example, are wavy or are adapted in their contouring to the flow conditions of the air-cooled condenser or are intended by their positioning and contouring influence on the flow conditions to take.
  • This means that the contact bodies can also have a certain conductive or deflecting function with respect to the cooling air flow, depending on the positioning and contouring.
  • the amount of water to be introduced into the contact bodies is selected such that no significant excess is produced, which would lead to a wetting of the installation. Therefore, a metering system controlling the amount of water to be introduced into the contact bodies is provided, which precisely supplies the contact body with precisely the amount of water which has to be supplied under the given climatic conditions and operating conditions of the system in order to ensure maximum evaporation in the area of the contact bodies.
  • This may be a control circuit or a control circuit equipped with corresponding measuring devices. The measuring devices detect whether at certain measuring points outside the contact body water is present, which suggests that the contact bodies too much water has been supplied to the evaporation.
  • a metering line extends with a plurality of openings through which the water to be evaporated can be introduced into the contact body.
  • This may be a rigid or flexible line that runs in the edge region of the contact body.
  • a dosing line can introduce water, for example from above, into a contact body.
  • the water runs down inside the contact body, wets its surface and evaporates within the cooling air flow. The amount of water is metered so that it passes on its way through the contact body straight to the lower end and partially evaporated already on the way there.
  • the metering lines are arranged on the cooling air flow facing or facing away from the surface of the contact body.
  • the paths that the water has to cover within a plate-shaped contact body are shorter and it ensures a more even distribution of the cooling water, which also simplifies the dosage.
  • the metering line is embedded in the contact body. This can be realized, for example, by a meandering dosing line which is positioned, for example, between two contact bodies formed as a nonwoven. Through the metering both contact bodies are wetted equally with water. The risk of water escaping uncontrollably from the fleece is thereby minimized.
  • the water to be evaporated is preheated in the metering, by heat transfer from the condensation elements to the metering.
  • the metering lines can extend between the end faces of the condensation elements and the contact bodies attached to the end faces. The preheated in this way water extracts the condensing elements to a small extent heat and evaporates faster in the contact body. This increases the efficiency of such an air-charged capacitor.
