Definitions
- the invention relates to an insulating cassette as part of a shell of under medium pressure standing facilities of a steam generator, for example, as pipe jacket insulation with a substantially closed sheet metal housing, which completely encloses a Dämmstoff spallung.
- Such insulation cassettes are often used for thermal insulation of pipelines to steam generators.
- the known insulating cassettes are half-shell-shaped sheet-metal cassettes, which are filled with mineral wool, fiberglass wool or similar insulating materials. These are described for example in DE 29 23 094 A.
- the sheathing of the insulation is done by a blending of the insulating material, for example with zinc sheet.
- the use of closed insulation cassettes has been proven that completely enclose the insulation material.
- the sheet metal housing of the insulating cassettes should provide adequate protection against mechanical damage to the insulating material.
- Insulating cassettes of the type described above are provided for example for lines up to about 800 mm in diameter and an internal pressure of 160 bar at about 300 0 C media temperature. It is easy to imagine that the leak jet of such a line can enter relatively high mechanical forces in the Isolierkassette.
- the invention is therefore based on the object to improve an insulating cassette of the type mentioned in this regard.
- an insulating cassette as part of a jacket of devices under pressure of a steam generator, for example as pipe jacket insulation with a substantially closed sheet metal housing, which completely encloses a Dämmstoff spallung, wherein the insulating cassette is characterized in that the Dämmstoff spallung comprises an airgel.
- Airgel in general and within the meaning of the invention are to be understood as meaning highly porous solids in which up to 95% of the volume consists of pores.
- This material as a filling material for an insulating cassette has the advantage that, for example, material emerging from the insulating cassette is easier to bear out of a water cycle because of its physical properties.
- an inorganic airgel is provided as insulant filling, which is not wettable, which is buoyant and which is not flammable.
- an insulating cassette has been found in which the Dämmstoff spallung comprises a silicate airgel.
- silicate aerogels may, for example, have a pore diameter of about 20 nm with a porosity of> 90%.
- the density of the material can be between 90 and 100 kg / m 3 .
- the thermal conductivity can, for example, about 0.018 W / rn-K at 25 ° C.
- Such a material may have an inner surface area of about 600 to 800 m 2 / g. The material is therefore excellent as an insulating material for the purposes described above.
- silicate airgel a material having the trade name "Nanogel” marketed by CABOT Corporation can be used.
- the insulation filling comprises an airgel as granules, preferably with a mean grain size of 0 to 4 mm.
- Such granules have particular advantages in handling. This can be filled into corresponding filling openings of sheet metal cassettes. Insulating cassettes can be filled with the highest possible packing density.
- the Dämmstoff spallung comprise at least one airgel molded body.
- a shaped body could be adapted to the shape of the preferably dimensionally stable sheet metal housing.
- the sheet metal housing of the insulating cassettes can for example consist of austenitic steel.
- the airgel is not translucent.
- a suitably treated airgel can be used. This has the advantage that the infrared reflectivity of the sealing material used is increased, whereby the insulating effect is improved.
- the insulating material filling may comprise graphite and / or metal oxide dust.
- the dust can be present for example with an airgel granules in homogeneous mixture.
- the insulating cassette according to the invention has an approximately C-shaped cross-section and is provided with fastening means with which mutually complementary trained insulating cassettes are assembled to form a substantially closed tube shell.
- the insulating cassette can be adapted to any desired contour of a media-carrying device to be insulated.
- Figure 1 is a schematic view of a pipeline lined with insulating cassettes according to the invention
- FIG. 2 shows a plan view along the arrows II-II in FIG. 1,
- FIG. 3 shows a longitudinal section along the arrows III-IM in FIG. 2,
- Figure 4 is an exploded view of an alternative embodiment of the insulating cassette according to the invention.
- Figure 5 shows the insulating cassette of Figure 5 in the assembled state.
- FIG. 1 shows a pipe section 1 of a hot runner leading a pressurized medium.
- the pipe section 1 is lined with insulating cassettes 2 according to the invention, wherein the insulating cassettes 2 each have a C-shaped cross-sectional profile and two mutually complementary insulating cassettes 2 are each assembled with fastening means 3 to form a closed, tubular insulating jacket 4.
- Suitable fastening means include, for example, clip-type buckles known per se.
- Each insulating cassette 2 consists of a riveted or welded sheet metal housing 5, preferably made of austenitic steel sheet. The sheet metal housing is fully closed and closed at the end faces 6 and provided with an insulating material filling 7.
- Insulating cassettes 2 comprise an insulation filling in the form of a granulate of a silicate airgel.
- This is a granulate with an average particle size of 0 to 4 mm, comprising as its main component trimethylsiloxy-modified silica gel.
- This has a porosity of> 90%, a pore diameter of about 20 nm, a bulk density of between 90 and 100 kg / m 3 and a thermal conductivity of about 0.18 W / m K at 25 0 C.
- the specific O The surface area is between 600 and 800 m 2 / g.
- the airgel is non-combustible, non-wettable and buoyant.
- the granules are filled in the insulating cassettes through the openings 8 provided on the front sides thereof.
- the openings 8 are then closed with lids 9.
- the cover 9 can be welded, bolted or riveted.
- Figures 4 and 5 show another embodiment of the insulating cassette 2 according to the invention.
- the Dämmstoff spallung 7 is formed as a shaped body 10, the shape of the shape of the dimensionally stable sheet metal housing 5 is adjusted.
- the molded body 10 is suitably inserted into the sheet metal housing 5, the end face 6 is closed with a correspondingly formed cover 9.
- the airgel is improved by a coloring in its infrared reflectivity, ie in its insulating properties with respect to heat radiation.
- a pulverization of the shaped body 10 with graphite and / or metal oxide dust comes into consideration.
- the granules can be mixed with graphite and / or metal oxide dust, wherein graphite and / or metal oxide dust in a proportion of 1 to 4 ma% of the mixture are involved.
