Definitions

  • the invention relates to a regenerative heat exchanger according to the preamble of claim 1 and a radial seal for use in a regenerative heat exchanger according to the preamble of claim 8. Furthermore, the invention relates to a method for separating gaseous media in a regenerative heat exchanger according to the preamble of Claim 10.
  • a regenerative heat exchanger is eg off DE 111 3534 known.
  • a normally cylindrical heat storage body which is designed for the flow of gaseous media.
  • These heat storage bodies are divided into sectors by radially extending walls, hereinafter called sector walls.
  • the sector walls extend substantially continuously from the longitudinal axis of the heat storage body to the heat storage edge and are aligned parallel to the longitudinal axis or lie in a plane therewith.
  • the sector walls are formed continuously from one heat storage end face to the other.
  • the sector walls are usually evenly distributed in the heat storage body, so that result in sectors of the same shape and the same volume.
  • the heat storage body partially have diameters of 20 m and more, the sectors are subdivided for construction reasons by the introduction of additional walls in several, permeable by gaseous media heat storage chambers, often a plurality of heat storage chambers within a sector in heat storage body radial direction are arranged one behind the other.
  • recuperative or regenerative heat exchanger systems are available for exchanging heat between gaseous media.
  • the flow of the heat-emitting medium is applied directly to one or more streams of heat-absorbing media and the heat is transferred directly through a partition wall.
  • regenerators is transfer the heat by means of a heat-storing intermediate medium.
  • heat-storing intermediate media are arranged in regenerative heat exchangers in the heat storage chambers of the heat storage body. These are often layered sheet steel layers, which can be enamelled if necessary. These are often designed as basket systems, which can then be used as a whole in a heat storage chamber and fill them. Alternatively, some ceramic bodies or heating surfaces made of plastic are used as heat-storing intermediate media.
  • the heat storage body is either fixed or rotatable about its longitudinal axis, wherein in the former case of a "stator" and in the latter case of a "rotor” speaks.
  • the rotor housing including the gas duct connections attached thereto, is fixed, so that the rotor rotates through the different gas flows.
  • so-called rotary hoods are arranged. In both variants, therefore, the various areas of the heat storage body alternately flows through all the existing gas flows.
  • the heat-emitting gaseous medium flows through the heat storage body from one end face to the other and thereby heats the heating elements arranged therein in the individual heat storage chambers, which store this heat. Further, one or more heat-receiving gaseous media flow through the heat storage body, also from one end face to the other.
  • the heated heating elements are flowed through by the cold gas streams and thus heat them.
  • a hot, heat-emitting exhaust gas flow and a cold, heat-absorbing air flow are often passed through the heat storage body. This is the process of air preheating (Luvos). Subsequently, the heated air is supplied to a furnace and accordingly referred to as combustion air or combustion air.
  • combustion air or combustion air The increased heat of combustion air by the heat exchanger substituted parts of the energy contained in the fuel, whereby the amount of fuel required for the firing is reduced. Consequently, the amount of CO 2 released during firing is also reduced.
  • heat exchangers can also be used for gas preheating (Gavos).
  • heat exchangers which are designed as so-called DeSOx systems, for example, a hot raw gas with a high SOx content is cooled and heated a clean gas with a low SOx content.
  • DeNOx plants in turn, a hot clean gas with a low NOx content is cooled and a crude gas is heated with a high NOx content.
  • the heat-emitting gas stream and the one or more heat-absorbing gas streams according to the countercurrent principle are conducted opposite one another through the heat storage body.
  • the heat-absorbing gas is led out of the heat storage body.
  • the hot side of the heat exchanger On the opposite side, the cooled, heat-emitting gas is blown out and the still cool heat-absorbing gas is blown. Accordingly, this is the so-called cold side.
  • a regenerative heat exchanger which is designed, for example, for air preheating, it therefore has a casein inlet and an air outlet on its hot side and a gas outlet and an air inlet on its cold side.
  • the exhaust gas thus flows through an exhaust gas region which extends from the hot to the cold side of the heat exchanger, while the combustion air flows through a combustion air region which extends from the cold to the hot side.
  • the division of the heat storage body into heat storage chambers is provided to prevent the various gas streams from mixing with each other. Through the various chambers, separated from each other, simultaneously heat-emitting gas or heat-absorbing gas out. In order to ensure a flow through or around the heat storage intermediate chambers located in the heat storage chambers, the heat storage chambers are open at the end faces of the heat storage body.
  • a radial seal is often formed as a bar or bar and extends orthogonal to the axis of rotation or longitudinal axis of the heat storage body extending over the diameter of the heat storage body. In this case, it is usually flat and runs through the heat storage body center. It is often made of metal or other materials such as e.g. Made of plastic and may be formed in one piece or in several pieces.
  • the radial seal may be designed to be adjustable in the direction of the heat storage body longitudinal axis, that is to say away from the heat storage body or towards the heat storage body. Frequently, the radial seals are performed in this way to compensate for heat-induced deformation of the heat storage body can.
  • the sealing gap between the radial seal and the heat storage body face can be minimized to leakage between the various To reduce gas flows.
  • the maintenance of a minimum sealing gap is necessary to ensure the rotatability of heat storage body and radial seal relative to each other.
  • the radial seal consists of two or more seal arms, with a seal arm extending substantially from the axis of rotation to the outer edge of the heat storage body.
  • the number of seal arms usually depends on the number of different gas streams present. Flow, for example, in a heat exchanger using a rotor as a heat storage body, two gas flows through the rotor, two sealing arms are provided both on the cold and on the hot side, with three gas flows three sealing arms, etc. in that the radial direction relative is arranged stationary to the rotational movement of the rotor, the openings of the heat storage chambers rotate under the radial seal therethrough. In one complete revolution of the rotor, each point of the end faces of the rotor is once below or above each seal arm.
  • the radial seals have been formed in known regenerative heat exchangers so that in each rotational position, that is, any position of the heat storage body and radial seal to each other, a sector wall below and above a sealing arm.
  • the various gas areas for example, the combustion air area and the exhaust gas area, always separated by a radially extending from the axis of rotation to the heat storage body edge sector wall.
  • the continuous closing and opening of the heat storage chambers creates permanent, mechanical vibrations. These are caused by the different pressure conditions that occur when opening and closing the heat storage chambers and have a pulsating effect on the radial seals. This process is also referred to as "pumping" the seals.
  • the intensity of this pumping and thus also the intensity of the action on the radial seal is dependent on the existing pressure differences between the different Casströmen and the surface of the seals. As this process is repeated continuously, the mean sealing gap height increases.
  • the wear of the radial seals and the end faces of the heat storage body is considerably increased. These factors result in an increase in leakage.
  • a heat exchanger is known in which the radial seal identifies two dovetail-shaped sealing arms.
  • a simultaneous coverage of all chambers or heat storage chambers is achieved, which are arranged in the radial direction of a sector of the rotor formed as a heat storage body.
  • Such simultaneous coverage of the chambers is also apparent from the patents DE 11 13 534 B . GB 676,129 A . US 3,968,569 A and WO 93/19339 A known. Again, the adverse pumping of the seals occurs, as described above.
  • the invention is therefore based on the object to show ways how the pumping of the seals and thus the leakage between the different gas areas, as well as the wear on the radial seals and on the end faces of a heat storage body can be reduced.
  • the regenerative heat exchanger thus has a cylindrical heat storage body, which is divided by a plurality of radial sector walls into sectors, wherein in each sector at least two radially arranged in succession heat storage chambers are provided.
  • the heat storage chambers are designed to flow through the gaseous media and accordingly have openings in the region of the end faces of the heat storage body.
  • the radial seal is designed so that it covers each heat storage chamber opening alternately completely upon rotation of the rotor or the rotary hoods.
  • the openings of the heat storage chambers are constantly closed and reopened during operation, each opening is covered at least once from each radial seal at a complete rotor circulation or rotary hood circulation.
  • the heat chambers are continuously formed from one end face to the other, it is expedient to shape and arrange the radial seals on the two end faces in such a way that both openings of a chamber are closed and opened substantially simultaneously and thus this chamber is completely closed with a corresponding rotational position. This is advantageously achieved in that the arranged on the two end faces, opposite radial seals are formed substantially uniform and congruent.
  • the radial seal is now designed so that it at least partially covers the opening of at least one of these heat storage chambers of the radially successively arranged heat storage chambers of a sector in each rotational position, that is, in any position of heat storage body and radial seal.
  • the basic idea of the invention is thus to arrange the opening surfaces of the heat storage chambers arranged one behind the other within a sector and the covering surface of the radial seal relative to one another such that never all radially consecutively arranged heat storage chambers of a sector at the same time and thus at no angular position of the rotor or the rotary hood are covered by the radial seal.
  • this relative arrangement can be achieved both by a corresponding design of the radial seal and by a corresponding design of the heat storage chamber geometries.
  • the geometries of the sector walls and the heat storage chambers are maintained and the adjustment is made in the radial seal.
  • all geometries that produce the effect described above can be used for the radial seal.
  • the radial seal is designed such that it completely covers at most one heat storage chamber of the heat storage chambers arranged one behind the other of a sector at any given time, that is, at each rotational angle position of the rotor or the rotary hoods.
  • each radial seal comprises at least two sealing arms.
  • at least two sealing arms of the radial seal which extend substantially from the longitudinal axis radially outwardly to the heat storage body edge, at least one sealing arm is formed asymmetrically.
  • the geometry of the at least one Sealing arm is shaped such that the surface of the sealing arm is not symmetrical in a plan view. This excludes both axis symmetry and point symmetry. It can therefore find no axis or no point around which the Dichtarm Structure can be mirrored. Such a design can be achieved particularly well a time-delayed coverage of the individual heat storage chambers.
  • the individual sealing arms of the radial seal are subdivided into sealing arm segments.
  • the individual segments are arranged one behind the other in the radial direction and close directly to each other, so that they assemble into a seal arm.
  • the two outer edges of a segment are each formed substantially linear.
  • the outer edges of adjacent Dichtungsarmsegmente offset from each other and alternatively or additionally angled with respect to their adjacent outer edges.
  • the outer edges are considered on the same seal arm side.
  • the heat storage bodies are formed so that they have a plurality of coaxial annular walls. These annular walls are often cylindrical and have the heat storage body longitudinal axis as a common axis. Thus, the annular walls cut through the individual sectors and divide them into subsectors in the radial direction. These subsectors may correspond to the dimensions of a heat storage chamber. However, it is also possible in principle to subdivide the subsectors further into several heat storage chambers. When a heat storage body is subdivided by such annular walls into subsectors, it is preferred that the individual seal arm segments of the seal arms be configured to extend radially across substantially one subsector or a plurality of adjacent subsectors.
  • seal arm segment Corresponds to a subsector of a heat storage chamber, it is appropriate that over this subsector extending seal arm segment is formed to cover the chamber. It is thereby achieved that the edge offset between two sealing arm segments, or the point of intersection between two mutually angled outer edges of two adjacent sealing elements, is arranged substantially over a region against which two heat storage chambers or two subsectors abut one another.
  • the formation of the individual sealing arm segments can be better adapted to individual sub-sectors, so that the covering order of the individual sub-sectors or heat-storing chambers can be optimized during operation, whereby the oscillation volume is further reduced overall.
  • At least one seal arm is divided into three seal arm segments, wherein the inner segment closest to the axis of rotation is cone-shaped.
  • the cone-shaped inner segment is aligned so that it widens substantially in the radial direction.
  • the adjoining middle segment tapers in the radial direction and preferably at least one edge of the middle segment is offset relative to the adjacent edge of the inner segment in the heat storage body circumferential direction. Due to the tapering of the middle segment in the radial direction, the edges of the middle segment are angled with respect to the inner cone-shaped outwardly widening segment.
  • the cross-sectional area of the outer segment widens again in the radial direction and its edges are thus arranged angled relative to those of the middle segment.
  • the radial seal is formed so that the inflow and outflow surfaces are substantially equal for the respective gaseous media.
  • the inflow and outflow surfaces of the various gaseous media may further vary in size and may be adapted to the specific requirements of each such, e.g. maximum permissible pressure losses, to be adjusted.
  • the existing of at least two sealing arms radial seal thus has at least one sealing arm, which is formed asymmetrically. Such a design reduces the amount of pumping acting on the seals.
  • the method therefore consists of alternately completely covering the openings of the various heat storage chambers in the heat exchanger operation in the case of an already described heat storage body of a regenerative heat exchanger with sectors and in the radial direction one behind the other, throughflowable heat storage chambers for separating the different gas flows. That is, the heat storage chambers are permanently closed and reopened. As a result, a separation between the individual gas streams is achieved.
  • the heat storage chambers are covered in such a way that in the case of heat storage chambers arranged radially behind one another within a sector in each operating state of the heat exchanger at least one heat storage chamber is at most partially covered.
  • the opening of at most one of these heat storage chambers is completely covered in each operating state.
