Definitions

  • two or more containers which contain heat storage masses through which the exhaust air flows and whose one ends are connected to one another via at least one combustion chamber.
  • the pollutant-containing exhaust air which contains combustible, gaseous or vaporous constituents, such as solvent vapors, and is removed from a production or upgrading process, first flows through one of the containers, is heated by previously heated heat storage mass and then reaches the combustion chamber, in which the Pollutant components, if necessary with the addition of a fuel, are oxidized at temperatures of, for example, between 800 and 1000 ° C., in particular to CO 2 and H 2 O.
  • the hot exhaust air cleaned in this way then flows through the other container and heats the heat storage mass contained therein.
  • All containers are alternately fed with exhaust air to be cleaned or through which clean gas to be cooled flows.
  • a purging process is usually carried out, ie the container previously charged with exhaust air to be cleaned is purged with clean gas or fresh air in order to avoid pollutant components of the exhaust air to be cleaned being carried over into the clean gas; alternatively, the polluted gas volume is extracted from the container under consideration and supplied to the exhaust air that is still to be cleaned.
  • each container has an inflow flap, an outflow flap and a suction or purge gas flap or a rotary slide valve is assigned, which takes over the functions of the flaps mentioned.
  • flaps When flaps are used, considerable drive energy is required for flap actuation, but also a high level of control effort. Since the flaps are usually operated with compressed air, they open and close suddenly without any special additional devices, so that strong pressure fluctuations occur in the system, which can have a negative effect on the process preceding the exhaust air purification. Emission peaks in the clean gas (higher proportions of pollutants) also arise when the flaps are switched due to the short-term formation of bypass short-circuits between the exhaust air supplied to the system to be cleaned and the clean gas removed from the system.
  • the invention had for its object to provide a device for thermal exhaust air purification, the basic structure of which enables the device to be designed without further ado so that all or at least some of the disadvantages of the known devices described above can be avoided or avoided .
  • each of the containers has at least one first opening for connecting the interior of the container to the combustion chamber and at least one second opening for supplying exhaust air to be cleaned to the interior of the container or removal of clean gas from the interior of the container, which are located at opposite ends of the container in the flow direction of the container, as well as with an exhaust air supply duct, a clean gas discharge duct and control devices for aging End connecting the second container openings with the exhaust air supply duct and the clean gas discharge duct.
  • the invention proposes to design such a device that at least a first and a second slide valve associated with the respective container is provided for each container, each of the first slide valves on the one hand with the exhaust air supply channel and each of the second slide valves on the one hand communicates with the clean gas discharge duct, the first and second slide valves on the other hand communicate with the second container openings of the containers assigned to the valves, all first slide valves have a first valve slide and all second slide valves have a second valve slide, drive devices are provided for synchronous displacement of all valve slides, and the valve slides are designed in this way and are displaceable by the drive devices in such a way that the simultaneous and synchronous displacement of all valve slides from the slide valves assigned to the two containers always closes the first slide valve of one container and the second slide valve of the other container, as long as the second slide valve of one container and the first slide valve of the other container are at least partially open or the second slide valve of one container and the first slide valve of the other container s are closed as long as the first
  • the design of the containers holding the heat storage masses is at least almost completely free, so that, if desired, the rectangular cuboidal ceramic honeycomb bodies available on the market can also be used as heat storage masses; since all valve spools are to be moved simultaneously and synchronously, the prerequisite for the use of at least several valve spools common drive, which is z. B. can be an electric geared motor so that the opening and closing of the second container openings does not occur suddenly; Finally, the valve spool can be easily designed so that bypass short circuits between exhaust air flowing into the device to be cleaned and clean gas flowing out of the device and thus emission peaks in the clean gas leaving the device are avoided. The fact that all valve spools are moved simultaneously and synchronously also significantly reduces the control effort for such a device in comparison to the known devices.
  • a further reduction in the effort for the actuation of the valves of the device according to the invention can be achieved in that all first slide valves lie in a first plane and are arranged at equal distances from one another in a first direction, in that all second slide valves lie in a second plane and in a second direction are arranged at equal distances from one another, and that all first slide valves have a common first valve slide which is displaceable in the first plane in the first direction and all second slide valves have a common second valve slide displaceable in the second plane in the second direction , because then a maximum of two drives for the valve spool is required, namely a first drive for the first and a second drive for the second valve spool.
  • first and the second valve slide are then displaceable in the same direction and the containers are arranged in succession in this direction, it is even possible to actuate both valve slide by a single motor.
  • the device according to the invention could, for. B. "Carousel-like" design, ie the containers could be arranged along a circle, in which case the two valve slides Circular shape or the shape of part of a circular ring and would be movable around the center of the circle.
  • the construction becomes simpler, however, when the containers are arranged in succession in a straight direction and form a row of containers and the valve slides extend in this direction, e.g. B. have the shape of narrow, elongated rectangles that are pushed back and forth in their longitudinal direction;
  • a valve slide common to these two valves could also be provided for the first and the second slide valve of each container, which extends across the row of containers and can be pushed back and forth in its longitudinal direction.
  • first and / or the second valve slide is formed by a flexible endless belt which has at least one opening for each of the first and second slide valves and is guided over two deflection rollers arranged in this way is that the one strand of the endless belt extends over the entire row of containers, because then it only needs a motor that runs constantly in the same direction in order to constantly drive at least one of the deflecting rollers.
  • first and second levels are identical, it is even possible to work with a single endless belt and with only two deflection rollers.
  • Valve spools designed as endless belts always driven in the same direction not only have the advantage over reciprocating valve spools that a simpler valve spool drive can be used, but also a valve spool that is always moving in the same direction is also subject to less wear, since only sliding friction occurs on the valve slide and there is never a need to overcome static friction.
  • each of the containers with only a single second opening, from which a channel extends, which branches between the container and the exhaust air supply channel and the clean gas discharge channel into two channels, to which a first and a second slide valve is assigned .
  • each container has two second openings, one of which is connected to the first and the other to the second slide valve assigned to the container in question via a respective channel.
  • valve spools Especially when working with two endless belts as valve spools, it is advisable to arrange the first spool valves in the exhaust air supply duct and the second spool valves in the clean gas discharge duct and to design the structure so that each spool valve - the container assigned to this valve - is aligned connecting pipe protruding into the channel in question and sealed off from the channel wall. Then the valve slides do not have to pass through any channels or connecting pieces, but can either seal the ends of the pipe connecting pieces projecting into the exhaust air supply channel or the clean gas discharge channel or release them for flow.
  • the endless belts are designed so that - in a side view of the runs acting as a valve slide in the running direction of the latter - the openings of one run do not overlap those of the other run.
  • the exhaust air to be cleaned will be referred to as raw gas for the following, and the cleaned exhaust air as clean gas.
  • the system according to the invention has three containers I, II and III arranged in a straight line one behind the other, each of which according to the invention has the same and preferably a rectangular cross section (see FIG. 2).
  • Each container has an upper opening 10, the cross section of which is preferably equal to the cross section of the actual container, and above the containers there is a longitudinal channel 12 which extends over all three containers and communicates with them via their upper openings 10, but otherwise is closed on all sides.
  • In one side wall 12a of the longitudinal channel 12 there are two burners 14, in each case in the transition area between two containers; with the help of this z. B.
  • the pollutants contained in the raw gas burned provided that the nature and concentration of the raw gas is not suitable for the heated raw gas to burn in the longitudinal channel 12 by itself, even after the raw gas has been heated accordingly; alternatively, the pollutant components of the raw gas could, if necessary, also be catalytically oxidized if they are suitable for such a catalytic oxidation - in this case, the heat storage masses contained in containers I to III, which will be described later, would be coated with a suitable catalyst.
  • each of the containers I to III has two downwardly tapering scoops, one of which is part of a raw gas inlet duct 16 and the other part of a clean gas outlet duct 18 and to each of which a pipe socket 20 or 22 connects, which together with the adjacent scoop forms the relevant channel 16 or 18.
  • Each of the containers I to III thus includes a raw gas inlet opening 24 and a clean gas outlet opening 26, as can be seen in FIG. 2, however, each of the containers also has a purge air opening 28 which is adjacent to the raw gas inlet opening 24.
  • the pipe socket 20 of the raw gas inlet channels 16 protrude into a raw gas channel 30 and are tightly guided through the wall of this channel; in the same way, the pipe sockets 22 of the clean gas outlet channels 18 protrude into a clean gas channel 32.
  • the pipe sockets 20 and 22 all end in the same horizontal plane, and in the preferred embodiment the lower opening cross sections of the pipe sockets 20 and 22 are square and of the same size, as is also the case for the flow cross sections of the channels 16 and 18 at other locations.
  • the raw gas channel 30 has the shape of a hollow, elongated cuboid, which is closed at its two ends except for a raw gas connecting piece 34; As indicated by an arrow in FIG.
  • the raw gas to be cleaned is fed to the raw gas duct 30 via the connecting piece 34.
  • the raw gas channel 30 and the clean gas channel 32 advantageously have the same dimensions and are at the same level.
  • All raw gas inlet channels 16 are assigned a common first endless belt 38, all clean gas outlet channels 18 a second endless belt 40.
  • These two endless belts should be flexible belts which are impermeable to gas over their cross-section, preferably made of thin, stainless steel, and at least the one main surface of the two endless belts facing outwards should be absolutely smooth.
  • the endless belt 38 running in the raw gas duct 30 is guided over a front and a rear deflecting roller 44 and 46, which are rotatably mounted in the raw gas duct 30 about horizontal and mutually parallel axes and of which e.g. B. the front roller 44 is driven by a motor 50 shown in FIG. 5.
  • the upper run 38a of the endless belt 38 lies against the lower ends of the pipe socket 20, as will be explained in more detail later with reference to FIG. 6.
  • both endless belts 38 and 40 are preferably driven by a single motor, in synchronism with same running speed and in the same direction, e.g. B. in the direction of the arrows shown in Figures 1 and 8.
  • a single motor for such a common drive, it is only necessary to pass the shaft 50a of the motor 50, indicated by dashed lines in FIG. 5, gas-tight through the walls of the clean gas duct 32 and the raw gas duct 30.
  • the bearings for the two deflecting rollers 44 and 46 have been omitted for the sake of simplicity.
  • a purge air duct 60 is integrated into each of the raw gas inlet ducts 16, the lower end of which forms the purge air opening 28 shown in FIG. 2 and over part of the length of the raw gas inlet duct 16, from below forth, is separated from the flow path of the raw gas flowing into the container in question by a partition 62.
  • each of the endless belts 38, 40 is guided in sliding guides at the lower end of the pipe socket 20 or 22 so that the respective endless belt tightly closes the associated pipe socket below, unless an opening is currently running in the Endless belt past the pipe socket (this will be discussed in more detail later).
  • a carrier plate 66 is fastened, for. B. welded, attached to the underside of a first seal 68, for example is glued.
  • the seal consists of such a material that it leads to a relatively low sliding friction between the seal and the endless belt in question, but leads to a good gas seal.
  • a plurality of threaded bolts 70 are fastened to the support plate 66 in the direction perpendicular to the plane of the drawing in FIG. 6, which hold and clamp through a clamping bracket 72.
  • a second seal 74, corresponding to the seal 68, and the associated carrier plate 76 are fastened to this tensioning bracket, and the seals 68 and 74 enclose a longitudinal edge region of the upper run (here the upper run 38a) of the relevant endless belt between them.
  • Each threaded bolt 70 passes through a compression spring 78 arranged between the carrier plate 66 and the clamping bracket 72, between the upper end of which and a nut 80 screwed onto the threaded bolt 70 the upper leg of the clamping bracket 72 is arranged so as to be vertically displaceable on the threaded bolt.
  • the compression spring 78 thus leads to the fact that the upper run of the relevant endless belt can slide between the seals 68 and 74, but these bear against the endless belt with the required sealing forces. The same applies to the four other sealing and guide points shown in FIG. 5.
  • FIG. 5 shows a purge air duct 86 running along the row of containers, from which a branch line 88 branches off for each of the containers I to III, which is passed gas-tight through the wall of the raw gas duct 30 and ends on the underside of the upper run 38a of the endless belt 38 .
  • This end of the branch line 88 is expediently provided with an annular sliding seal, against which the upper run 38a bears with slight pressure.
  • the purge air duct 86 is intended, for example, to supply fresh air via a blower are supplied in such a way that a certain excess pressure is always maintained in the purge air channel 86 (compared to the gas pressure within the containers I to III).
  • the steel belts forming the endless belts 38 and 40 are perforated in a periodically repeating manner, i. H. provided with gas passage openings.
  • the endless belt 38 has a purge air passage opening 100 and a raw gas passage opening 102 (successively in the direction of travel), while the endless belt 40 has only one opening, namely a clean gas, within each longitudinal section forming such a period Passage opening 104.
  • the endless belt 38 has a purge air passage opening 100 and a raw gas passage opening 102 (successively in the direction of travel), while the endless belt 40 has only one opening, namely a clean gas, within each longitudinal section forming such a period Passage opening 104.
  • the two openings 100 and 102 are closely adjacent to one another, but the openings are arranged in the two endless belts 38 and 40 such that they do not overlap when viewed in the direction of arrow B, at least then when the two endless belts 38 and 40 have been applied in phase with respect to one another on their deflection rollers 44, 46.
  • each of the containers I to III accommodates a heat storage mass, designated 92 overall, within a peripheral wall 90 that defines a rectangular and in particular a square cross section and is provided with thermal insulation (see also, for example, FIG. 1 and 3), which is composed of commercially available, cuboid-shaped ceramic honeycomb bodies 94, each of which has a multiplicity of flow channels 96 running in the vertical direction.
  • the heat storage mass contained in the relevant container or I or II or III 92 is therefore composed of a plurality of layers of honeycomb bodies 94 stacked one on top of the other, each layer being formed by 25 identically shaped honeycomb bodies 94 in the embodiment shown.
  • the flow channels 96 of each honeycomb body 94 are aligned with the flow channels of the honeycomb bodies arranged above and below this honeycomb body, so that there is a large number of vertical flow channels and consequently a relatively small pressure loss in each container I to III.
  • the description of the state which is shown in FIG. 8 should be started. If the system is in this state, raw gas supplied to the raw gas channel 30 flows through the raw gas passage opening 102 shown on the right in FIG. 8 into the container III from below, namely through its raw gas inlet opening 24. As will become clear from the following, the heat storage mass 92 is located of the container III in this state at a relatively high temperature, so that it heats the raw gas flowing through the heat storage mass from bottom to top. It then enters through the upper container opening 10 into the longitudinal channel 12 forming a combustion chamber, whereupon the raw gas in the longitudinal channel 12 is thermally cleaned, in particular when it flows past the burner 14 shown on the right in FIG. 1.
  • the clean gas thus formed flows according to FIG. 1 from right to left through the longitudinal channel 12 and through the upper opening 10 of the container I into it from above.
  • the hot clean gas gives off heat to this heat storage mass and heats it up before the clean gas leaves the container I via the clean gas outlet opening 26, through the one shown in FIG. 8 on the left Clean gas passage opening 104 passes through the upper run 40a of the endless belt 40 and flows into the clean gas channel 32.
  • the process described above takes a correspondingly long time (of course depending on the running speed of the endless belts).
  • the endless belt 38 briefly clears the purge air opening 28 of the container II, thanks to the purge air passage opening 100 shown on the right in FIG. 8.
  • Purge air is emitted in the time interval in which the purge air opening 28 of the container II is released the purge air channel 86 is pressed through the branch line 88 belonging to the container II into the container II, flows through it from bottom to top, takes raw gas residues still remaining in the container II and then reaches the longitudinal channel 12, where these raw gas residues are burned by the burner 14 located downstream.
  • the raw gas residues could also be sucked out of the container II via the channel 86 and fed to the raw gas still to be cleaned.
  • Another alternative is to purge the container II from top to bottom, with clean gas obtained from the raw gas that has flowed through the container III from the bottom to the top; In this case, too, the purging gas contaminated with pollutants would have to be returned to the raw gas still to be cleaned.
  • the purge air opening 28 of the container II is first closed and the clean gas outlet opening 26 of the container II is closed by the in FIG. 8 Clean gas passage opening 104 shown on the left slowly released; the clean gas outlet opening 26 of the container I is then closed, while the clean gas outlet opening 26 of the container II remains open for a relatively long time.
  • the raw gas inlet opening 24 of the container III is first slowly closed and at the same time the raw gas inlet opening 24 of the container I is slowly opened - if the latter is completely open, the raw gas inlet opening 24 is the Container III completely closed.
  • thermally cleaned gas coming from the containers I and III flows out as clean gas via the container II, which is followed by a phase in which the raw gas to be thermally cleaned only comes from the container I and the clean gas via the Container II flows out.
  • the raw gas inlet opening 24 of the container III is closed, its purge air opening becomes 28 released briefly and so the container III rinsed.
  • the clean gas outlet opening 26 of the container II is slowly closed and at the same time the clean gas outlet opening 26 of the container III is slowly released.
  • the clean gas outlet opening 26 of the container II is closed and the raw gas inlet opening 24 of the container II is slowly released, while the raw gas inlet opening 24 of the container I is slowly closed.
  • the container I While the raw gas inlet opening 24 of the container II and the clean gas outlet opening 26 of the container III are open, the container I is purged by temporarily opening its purge air opening 28. Thereupon the clean gas outlet opening 26 of the container III is slowly closed, at the same time the clean gas outlet opening 26 of the container I is slowly released. After closing the clean gas outlet opening 26 of the container III, the raw gas inlet opening 24 of the container III is slowly released and at the same time the raw gas inlet opening 24 of the container II is slowly closed, whereupon the process begins again.
  • raw gas to be cleaned is therefore always heated as long as it flows through one of the containers I to III and thus the previously heated heat storage mass 92 contained therein from bottom to top; Then, in the longitudinal channel 12, the gas is thermally cleaned, whereupon it flows through another of the containers I to III and thus the heat storage mass 92 contained therein from top to bottom, giving off part of its heat and heating this heat storage mass.
  • the containers are then switched so that the raw gas to be cleaned flows through the previously heated container from bottom to top and is heated in the process.
