Definitions

  • the invention relates to the design of a plate heat exchanger which is intended in energy technology for heat transfer between two gaseous media of different temperatures, ie between two flue gases or between a flue gas and the air. It is a recuperative heat exchanger that is used in particular for the reduction of NO x emissions in flue gases by means of an SCR method (selective catalythic reduction) in purified and sulfur-free flue gases.
  • the heat exchanger can also be used to preheat the combustion air.
  • Plate heat exchangers are known which are composed of metal sheets, some of which are trapezoidal. These are mainly radiators for space heating.
  • the GB 1238491 discloses a plate heat exchanger formed by a bundle of pairs of adjacent plates, the central areas of which are trapezoidal corrugated in the direction of the flow, with the edge areas being smooth.
  • the waves in the trapezoidal area of two adjacent plates are offset against one another and in this position form alternating channels for two heat-exchanging media.
  • One medium is guided in a straight line through the channels, while the other is fed in sideways in one of the edge areas and discharged sideways again from the other edge area.
  • the heat exchanger is made of plastic and is intended for smaller amounts of gas at a relatively low temperature.
  • the invention is based on the object of designing a heat exchanger intended for energy technology from accessible and affordable elements that enables a large amount of heat to be exchanged between gaseous media at temperatures of up to 300 ° C.
  • the plate heat exchanger comprises a plurality of with Pairs of parallel thermally conductive walls arranged at a distance, which are formed in each pair by reversely oriented trapezoidal sheets with alternating channels and webs.
  • the webs in each pair are in contact with one another, and the channels form channels for the flow of the second medium.
  • the gaps between the individual pairs of sheets, which are covered over the entire circumference, are used for the flow of the first medium.
  • At both ends of the web of each trapezoidal sheet an opening for the supply and discharge of the first medium is formed.
  • the metal sheets of each pair are gas-tightly connected at the lateral edges and on the circumference of the openings, and the facing of the gaps is gas-tight.
  • spacer elements can be inserted between the metal sheets.
  • the channels formed in the pair of sheets open into a supply or discharge pipe for the second medium, and the openings in the webs of the edge sheets open into a supply or discharge manifold for the first medium.
  • distribution troughs can be connected to the supply manifold for the first medium, which pass through the openings in the webs.
  • the gaps between the pairs of sheets are provided with closable cleaning openings at the bottom of the sides.
  • the heat exchanger according to the invention is formed by a plurality of spaced-apart pairs of parallel heat-conducting walls, s. Figs. 1 and 2 .
  • the walls of each pair 1 are formed by reversely oriented trapezoidal sheets 2 with alternating channels 3 and webs 4 .
  • the webs 4 in each pair 1 lie against one another, and the channels 3 form channels 5 for the flow of the second medium.
  • Gaps 6 located between the individual sheet metal pairs 1 serve for the flow of the first medium.
  • an opening 7 is formed for the supply and discharge of the first medium.
  • the sheets 2 of each pair 1 are gas-tightly connected at the lateral edges 8 and on the circumference 9 of the openings 7 , and the gaps 6 are faced over the entire circumference, with a profiled facing strip 10 at the end, the facing of the gaps 6 being gas-sealed.
  • the channels 5 formed in the pair of sheets 1 open into a supply or discharge pipe (not shown) of the second medium, and the openings 7 in the webs 4 of the edge plates 2 in a supply or discharge manifold 11, 12 of the first medium, see FIG . Fig. 6 .
  • Distribution channels 13 which go through the openings 7 in the webs 4, are connected to the supply collecting pipe 11 of the first medium.
  • the facings of the columns 6 between the pairs of sheets 1 are provided with closable cleaning openings at the bottom of the sides, which means cleaning the Columns 6 allows during maintenance.
  • the present heat exchanger differs from the known types of plate heat exchangers in that it is formed by conventional rolled, thin-walled trapezoidal sheets, which are placed against one another in pairs and connected in a gas-safe manner at the edges.
  • the rolled profile sheets are usually produced in lengths of 6 to 12 m, and compared to tubes and other profile bars, they are inexpensive.
  • the construction described is characterized by an adequate rigidity, which enables easy assembly and handling. Any major leaks can be eliminated by covering the respective holes.
  • the basic element of the heat exchanger is represented by a pair 1 of trapezoidal sheets which are put together in such a way that their webs 4 rest against one another, their lateral edges 8 being connected in a gas-safe manner by welding, soldering, or in some other way.
  • trapezoidal sheet metal pairs 1 rectangular openings 7 are punched at both ends of the webs 4 , the edges of which are welded or soldered together on the circumference 9 in a gas-safe manner.
  • These basic elements are placed side by side in such a way that columns 6 are created. This creates the structure of the thermally conductive walls.
  • the gaps 6 between two pairs of sheets 1 are covered - by means of profiled facing strips 10 (see Fig. Fig. 3 ) on the front sides of the heat exchanger and by means of smooth strips on the side walls.
  • This facing can be welded on or clamped with screws.
  • the second medium to be cooled (hot flue gases) is fed from below into the mouths of the channels 5 formed in pairs of sheets 1 and discharged from above.
  • the first medium air or flue gases to be heated
  • the distribution channels 13 equipped supply manifold 11 determined.
  • the distribution channels 13, the profile of which corresponds to the shape of the openings 7 ensure that the first medium is distributed into the gaps 6 between the sheet metal pairs 1. They are pushed into the openings 7 when the supply manifold 11 is assembled.
  • the same construction is located on the lower side of the heat exchanger to remove the heated first medium.
  • the distribution channels 13 do not require any compression in the openings 7, and so they can be produced and inserted with sufficient installation clearance.
  • the construction described differs from the known solutions of plate heat exchangers.
  • the individual panels made of trapezoidal sheet metal are of the same shape, which significantly simplifies production and assembly. It is not a problem to produce the inlet and outlet parts for the first medium with sufficient accuracy and reliably.
  • the proposed solution brings about an almost ideal countercurrent arrangement with a high efficiency of heat utilization. Trapezoidal sheets in various shapes and material thicknesses are always available, repeated production of uniform parts reduces production costs. These are much lower than with tube heat exchangers.
  • the heat exchanger can be fully assembled in production and delivered to the construction site as a whole. Cleaning and control can be carried out through the cleaning openings.
  • This heat exchanger is particularly advantageous for those companies where temperature reduction or preheating is involved with a large volume of flue gases or air to be preheated.
  • Such a case is provided by the exchangers the SCR denitrification method, where catalysts are used at 200 ° C to 300 ° C.
  • the flue gases must first be heated to the required temperature and then cooled down to the temperature suitable for the chimney or cooling tower. The low heat losses are then compensated for by steam heating or an additional burner.
  • the heat exchanger according to the invention can also be used for combustion air preheating or in other technologies that primarily work with clean media, e.g. with cleaned flue gases without solid foreign matter; however, the temperature of the medium must remain above the dew point.
