Definitions

  • the skirt and in particular its support flange tend to deform and the weight of the skirt is then no longer transmitted uniformly. to the carrier refractory material. Subjected then to too great efforts, the refractory material splits then breaks, which leads to a bad oblique position of the skirt and even in the extreme case to the fall of the skirt.
  • Patent document GB-2124932 describes an arrangement of a cyclone skirt intended to solve the problems of disassembling the skirt and of deformations due to thermal stresses. To do this, the skirt is divided into independent segments supported in the detachable upper part, by pieces welded to the wall of the cyclone or by direct bolting.
  • the arrangement allows the skirt to be maintained at its periphery and thus limits its deformation.
  • each shoe can be placed in a sheath secured to the metal casing of the cyclone body.
  • the inner end of the shoes is inserted into housings provided in the upper part of the skirt.
  • housings provided in the upper part of the skirt.
  • the housings provided in the upper part of the skirt are formed by a second horizontal annular flange arranged in the upper part of the skirt and by vertical spacers arranged between the two flanges.
  • a sealing device may be provided consisting of pieces of crown fixed on the upper flange of the skirt and inserted in a lining of refractory material housed in the cyclone body; preferably, these pieces of crown will be made of refractory material.
  • FIG. 2 represents in horizontal section, the arrangement of three shoes 3 distributed regularly over the periphery of the skirt 1. Preferably there are three shoes 3 but more than three shoes 3 can be provided.
  • FIGS. 3 and 4 is shown in detail a shoe 3 and the corresponding arrangement of the cyclone body 2 and of the skirt 1.
  • the skirt has only an upper annular flange 4 bearing on the shoes 3.
  • the shoe 3 consists of a hollow metal part which, in horizontal plane, has inclined walls narrowing its section to facilitate its disassembly.
  • the support and the guide of the shoe 3 is produced by a sheath 10 preferably made of metal which is integral with the metal casing 20 of the cyclone body.
  • the shoe 3 therefore rests on the lower part of the sheath 10.
  • Sealing elements 8, 9, 11 are placed at the end of the sheath 10, on the inside of the cyclone. These elements 8, 9, 11 are made of flexible insulating refractory material.
  • crown pieces 13 are inserted in the lining 11 and are fixed to the upper flange 4 of the skirt 1. This fixing is preferably carried out by bolting in the flange 4 with the interposition of a reinforcement piece 14.
  • a metal flange 15 over the entire periphery of the sheath 10.
  • This flange 15 serves as a stop, with the interposition of a seal with a flange 16 fixed, preferably by solder on the periphery of the shoe 3.
  • the stop of the flanges 15 and 16 defines the maximum insertion position of the shoe 3 in the housing arranged in the skirt 1. In this position the shoe 3 is made integral with the sheath 10 preferably by bolting the flanges 15 and 16.
  • shoe 3 The internal structure of shoe 3 is particularly visible in FIG. 4.
  • These walls 17 have a double function. They define a chicane circuit intended to convey a cooling fluid inside the shoe 3.
  • the outer end of the shoe 3 has an adequate number of orifices, in the example shown three, including two inlet orifices 18 and an outlet orifice 19.
  • the cooling fluid is therefore sent under pressure to the holes 18 and comes out through the hole 19.
  • This cooling fluid can be cold air or water for example. In the case of the use of dry air this air can possibly be returned inside the cyclone.
  • the walls 17 also have a function of reinforcing the structure of the shoe 3, forming stiffening ribs.
