Definitions
- the invention relates to a cyclone separator, in particular for the direct heat transfer from the hot exhaust gases of a rotary kiln cyclone float gas turbine heat exchanger plant for production of Cement clinker from cement raw meal, with tangential feeding of Gas and raw meal, Gutaustrag in the lower cyclone area and with by protruding into the cyclone separator at the cyclone ceiling releasably suspended by means of bolts and to a central Immersion tube for the gas removal composite dip tube segments.
- a cyclone separator is known from DE 198 25 206 A1.
- the life of the Immersion tube segments is also known in the hot gas cyclones even then shortened, if not free in the interior of the hot gas cyclone protruding lower ends of the dip tube segments, the a particularly abrasive attack by the oncoming hot gas-solid suspension are particularly protected.
- the invention is based on the object for cement clinker production plants with cyclone float gas heat exchanger system one Cyclone separator in particular hot gas cyclone with segmented To create immersion tube to securely fasten its immersion tube segments are, have a long service life and yet easy to produce and are mountable.
- segmentmented dip tube is that the dip tube segments are smooth, So have neither cast or welded hook parts etc., so that the dip tube segments of a simple to produce can consist of comparatively thin-walled metal sheet and do not have to be poured. With the top bottom this in itself smooth dip tube segments is a cross section each having a U-profile angle rail detachably connected, whose legs bez the top bez. Bottom of the dip tube segments embrace hook-shaped. While the dip tube segments Made of simple heat-resistant sheet steel, The attached separate angle rails made of cast steel consist.
- the separate angle rail shaped cast hooks at the top the uppermost around the Tauchrohrabel distributed series of Dip tube segments are arranged are by means of radial bolts to the inner surfaces of the dip tube segment tops curious; excited. With the separate angle rail shaped cast hooks manages a simple and safe suspension of the around the dip tube circumference distributed dip tube segments.
- the dip tube segments be formed as a composite body by at least the Immersion tube segment outside, on which the in the cyclone separator inflowing abrasive hot gas-solid suspension flows in, is coated in particular in such a way that on the metal sheet Webs of a metallic grid-shaped grate are arranged its openings filled with a heat-resistant ceramic material are.
- FIG. 1 shows a section of the cyclone ceiling of a cyclone separator 10, which are provided inside with a refractory lining 11 is.
- Tangentially hot gas and cement raw meal flow into the cyclone a plant for the production of cement clinker.
- a dip tube into which is composed of a plurality of segments and suspended from the cyclone ceiling 10.
- Figure 2 z. B. the two adjacent immersion tube segments 12 and 13 to see, in turn below the other dip tube segments 14th and 15 are attached.
- From the cyclone ceiling 10 is centrally after above the gas exhaust pipe equipped inside with a refractory lining 16 17 off.
- the head 24 of the bolt 21, the on the dip tube inside in a corresponding recess of the Immersion tube segment 12, 13, etc., and arranged in the spacer sleeve 20 is, in each case covered by a lid 23, which is the releasable Attachment of the dip tube segments against the high thermochemical Protects stress.
- the lid 23 can after his Assembly still by a tack weld at the cast hook part 18 etc. be assured.
- the thickened head 24 of the bolts 21 is in a recess of a cap 25 is inserted, by means of which the angular rail-shaped casting hooks 18 to the smooth dip tube segment 12 and this on the inside of the spacers 20 and whose inner web 19 can be tensioned.
- the bolts 21 point at radially outboard end nuts 26, by means of which they over Springs 27 are supported on the outer circumference of the spacers 20.
- the dip tube segments 12, 13, etc. be formed as a composite body by at least the dip tube segment outside, on which in the Cyclone separator incoming abrasive hot gas-solid suspension flows, is coated, in particular in such a way that the metal sheet 12 webs of a metallic grid-shaped grate are arranged, whose openings with a heat-resistant ceramic material 30 are filled.
- the surface the ceramic material 30 nor a coating of the lowest possible porosity have, in particular a glaze, glazing, enamelling Etc..
- one the intersection bump area on one side of the segments covering holding plate 31 may be arranged with four transverse pins 32, 33, 34, 35 passing through four corresponding holes in the four pushed through adjacent corners of the dip tube segments are, being on the inserted through four transverse bolts Crossbars 36, 37 are secured to secure the retaining plate 31.
