Definitions
- the invention relates to a compensator for the passage of a hot processor pipe through a wall, consisting of a process pipe which passes from a hot room into a cold room through a channel piece fitted into a breakthrough in the wall, and an insulation on the wall and an insulating inner tube, which encloses the process tube and an insulation outer tube, which rests on the inside of the channel piece and an angle flange which connects the far wall end face of the insulating outer tube to the process tube and an approximately hollow cylindrical, flexible fabric compensator, with the outer surface of the channel piece and the angle flange is connected.
- the implementation of a hot process pipe through a wall is a common task in power plants, waste incineration plants and similar facilities, if z. B. pipes for heat exchangers are to be led out through the wall through the hot furnace.
- the heat-carrying process tube expands through the hot, guided medium, so that it changes its position in relation to the wall feedthrough. This movement is compensated by a so-called "compensator".
- PS-DE 23 23 082 C2 proposes a soft material compensator for this task, which covers the joint between two mutually moving pipe sockets by a multilayer construction of flexible insulation materials with air layers, radiation chambers and baffles contained therein.
- the soft insulation material can be divided by the distances between see the layers retain radiant heat even more effectively.
- the cavities flow through cooling air, which protects the insulation material from excessive heating by convection.
- Type of breaking point, z. B. flue gas can escape from the interior into the environment.
- the invention has the task of developing a compensator, the thermal load of the
- Tissue compensator both by heat radiation and by Heat convection is largely reduced, the insulation should be both gas-tight and long-term resistant and can compensate in one embodiment, movements of the process tube in a wall passage in both the lateral and in the axial direction.
- the invention presents that there is a lateral clearance between the insulating inner tube and the insulating outer tube, and an insulating auxiliary tube, which extends from the angular flange and is fastened in the vicinity thereof, and is located at the lowest point, rests on the process tube
- Temperature extends to the far wall end face of the insulating inner tube and at the highest operating temperature is a distance away therefrom, wherein the distance is located at all operating temperatures relative to the insulating outer tube.
- the inner insulating tube practically consists of two parts, namely the (longer) insulating inner tube, which is closer to the hot space and leads through the wall and its counterpart, the insulating additional tube, which also rests on the process tube, but moves with increasing temperature in an ever-increasing distance to the insulation outer tube.
- An essential feature of the invention is that this distance between the two inner insulation tubes is always positioned opposite the insulation outer tube. This has the distinct advantage that radiant heat radiating through this distance hits the insulation outer tube and reflected from this to a part and is discharged to the other part, but does not hit the heat-sensitive tissue compensator.
- Groove is moved to the center of the compensator, so this gap surrounded on all sides by high-temperature and long-term-resistant insulating material. This makes it possible, on the front sides of the compensator as a material for the mechanical holders of the insulating material easy to procure and to be processed of the material such. B. use steel.
- One embodiment variant offers the possibility of compensating for lateral movements of the process tube, the direction of movement being oriented "laterally" approximately in the plane of the wall pierced by the process tube, which in most cases corresponds to a radial direction with respect to the process tube in the area of the wall leadthrough.
- Angle causes a - on the wall - lateral movement both an axial and a radial movement.
- this game determines how big the radial mobility should be.
- this lateral play in the first approach must be just as large as the lateral clearance between the insulation outer tube and the insulation inner tube or the insulation auxiliary tube. If, within the compensator, not only an elongation but also an additional curvature is to be expected thermally, the clearance between the insulation outer tube and the two inner insulation tubes must still be increased by the amount that can result from the expected additional curvature.
- the air space between the two inner insulation tubes and the insulation outer tube is noticeably enlarged and serves as a compensation for radial movements.
- this insulating inner pane comprises the insulating inner tube in full circumference.
- the invention proposes pins which are driven parallel to the surface of the insulating inner pane forward and then protrude into the insulating inner tube.
- the point of the process tube, on which the insulating disc is attached becomes the fixed point. If the axial position of the process tube should shift with respect to the isolation disc, thus, it is necessary that the insulating inner tube on the process tube sliding, so that no distance between the insulating disc and the resting thereon insulating inner pane is formed.
- the insulating inner pane must have at their ends a distance to the surrounding insulation, which is at least as large as the intended lateral play. But with the surface remote from the channel section, the insulating inner pane rests on the insulation of the wall.
- this steel construction also offers the possibility of protecting the compensator against the effects of water, which can be caused by broken pipes - so-called pipe breakers.
- water can be released in the hot room, penetrate the insulation on the wall of the hot room and settle on the lowest surface of the hot room, ie on the wall that separates the hot from the cold room.
- this water penetrates into the compensator, it causes corrosion damage there, which can prematurely destroy the steel parts of the compensator and thereby reduce its service life in an unpleasant way.
- the existing steel construction of the compensator can be made in the region of the wall so that the penetration of larger amounts of water is prevented in the compensator.
- the invention proposes that the cover plate, which carries the insulating disk in its main function, also additionally serves as protection against water.
- the cover plate which carries the insulating disk in its main function, also additionally serves as protection against water.
- it must be waterproof connected to the channel piece, z. B. by an appropriate welding. Then, when water has penetrated into the insulation on the wall and has been sucked up by it as by a sponge, it can no longer penetrate through a gap between the lens and the channel piece in the compensator.
- the insulation disc consists of a water-impermeable or at least water-resistant material.
- this insulating disk must have a clearance against the insulating inner pipe, so there is always an opening. This opening is closed by the insulating inner pane resting thereon.
- water level is high, water can penetrate through the gap between the insulating disk and the insulating inner pane into the interior of the compensator penetrate, which - as mentioned - there produces most unwelcome corrosion damage.
- the invention proposes that an additional metal disk is inserted between the insulating inner pane and the insulating pane. It is just as large as the insulating inner pane and slides with radial movements of the insulating inner pane on the insulating pane.
- the two discs should be made of elastic material so that they are pressed together by a certain spring force. Then the gap between the two columns is almost completely closed, so that no appreciable amounts of water can penetrate more into the interior of the compensator.
- the invention presents as a further refinement that the metal disk extends through the insulating inner pipe to the process pipe and is tightly connected there to it , z. B. by welding.
- the invention proposes for connecting the angle flange to the process tube, a pipe section as a holding nozzle, which surrounds the process tube and rests on it. This piece of pipe is welded with an edge on the angle flange.
- a cooling air supply can be integrated into the angle flange.
- the tissue compensator can thus achieve an optimum operating temperature for the tissue compensator.
- tissue compensator is meant not only a tissue that is coated with suitable insulation materials and permanently flexible and gas-tight, but also any other such sheet-like material that is malleable to a bellows construction, so in about a hollow cylinder, both on the angle flange and rests on the channel piece and can be held there by a clamping band with a clamp.
- the insulation tubes can of course consist of a one-piece tube. A simpler production, for. B. in a mold, is possible if the insulation tubes consist of at least two half-shells. These shells can then also be held together by a metal band with a clamp.
- the invention proposes that that portion of the angle flange on which the tissue compensator lies lies approximately parallel to the surface of the insulation outer tube.
- the inside runs parallel to the insulation HFrohr.
- At a maximum axial displacement of the angle flange can then create this area of the outside of the insulation outer tube.
- the above-described range of axial displaceability requires that the distance between the bearing area of the angle flange for the tissue compensator and the insulation outer tube corresponds at least to the lateral clearance provided between the insulation outer tube and the two inner insulation tubes.
- FIG. 2 longitudinal section as in FIG. 1 in hot operating state
- FIG. 3 exploded view of the most important components as an oblique image
- Inner edge of the cover plate 1a and insulating inner tube 2 corresponds to the clearance L between the laterally mutually displaceable components.
- the insulating inner pane 3 rests on the insulating disk 3a. It is attached to the pins 4 on the insulating inner tube 2 and has laterally relative to their front edges a range of motion in the insulation 5a. Otherwise, however, it lies flat in a corresponding recess of the insulation 5a.
- Figure 1 it is clear how the insulation inner pane 3 can move on the insulating disk, wherein the gap between the insulating inner tube 2 and the insulating disk 3a is always covered by the insulating inner pane 3. As a result, an axial mobility is made possible without connecting the air space between the insulating inner tube 2 and the insulating outer tube 2b to the hot space H.
- the game L is shown four times between the laterally mutually displaceable components.
- the actual required dimensions are all influenced by the thermally induced axial displacement of the process tube 6 relative to the wall 5.
- the dimensions denoted by L in FIG. 1 may deviate from one another in a practical construction example.
- the compensator according to the invention is drawn in hot operating condition, in which both in the axial and in the lateral direction, the maximum shift has occurred.
- the process pipe 6 Due to the very strong increase in the temperature, the process pipe 6 has also greatly expanded in the longitudinal direction, so that a distance Z between the insulating inner tube 2 and the insulating auxiliary tube 2a has been set.
- the invention recommends cooling air into the air space between the angle flange 1d, the tissue compensator 7 and the outside of the insulation outer tube 2b via the cooling air supply 1e.
- Figure 2 is visible in cross section that the insulation outer tube 2b is guided with its near-wall end telescopically in the channel piece 1. With its opposite end face it rests on the angle flange 1d and slides in axial movement on the surface of this angle flange 1d.
- the insulation auxiliary pipe 2a is firmly connected to the process pipe 6 in the region of the angle flange 1d, so that it moves away from the wall 5 together with the adjacent angular flange 1d when the thermal expansion of the process pipe changes.
- the insulating auxiliary pipe 2a is adjacent to the insulating tube 2 with the same profile on the process pipe. This is fixed in the region of the wall 5 via the insulating inner pane 3, which is connected to the pins 4, in the region of the insulation 5a. As a result, the insulating inner tube 2 does not move relative to the insulation 5a on the wall 5, even if the process tube 6 shifts in the axial direction.
- cooling air feeds 1 e can, for. B. connected via pipes with a common cooling air duct.
- an arrow is shown at the bottom left, symbolizing the cooling air flow.
- the holding pipe 1c is welded, which encloses the process pipe 6 (not shown here).
- the process pipe 6 (not shown here).
- a single pipe section is symbolically represented for the three parts: insulation inner tube 2, insulation auxiliary tube 2a and insulation outer tube 2b. Shown is how this pipe section is composed of two half-shells, which are held together with two metal bands 9.
- FIG. 3 does not show how the insulating outer tube 2b, with its larger inner diameter, encloses the slender insulating inner tube 2 and the insulating auxiliary tube 2a with the same diameters.
- FIG. 3 shows how four pieces of pins 4 are driven through the insulating inner pane 3. They protrude into the inner opening of the insulating inner pane 3 and meet there on the insulating inner tube 2 to fix it.
- Insulation 5a fastened 1b bracket, at the edge of the lens 1a
- insulation auxiliary pipe encloses the process pipe 6 and connects to the angle flange 1d
- 3 insulating inner pane lies on the insulating disk 3a on 3a insulating disk, between insulating inner pane 3 and cover plate 1a
