Definitions

  • This invention relates to a cyclone separator and, more particularly, to such a separator for separating solid fuel particles from gases discharged from a combustion system or the like.
  • cyclone separators are normally provided with a monolithic external refractory wall which is abrasion resistant and insulative so that the outer casing runs relatively cool.
  • these walls are formed by an insulative refractory material sandwiched between an inner hard refractory material and an outer metal casing.
  • these layers must be relatively thick which adds to the bulk, weight, and cost of the separator.
  • the outside metal casing of these designs cannot be further insulated from the outside since to do so could raise its temperature as high as 815°C(1500°F) which is far in excess of the maximum temperature it can tolerate.
  • a cyclone separator in which heat losses are reduced and the requirement for internal refractory insulation is minimized.
  • a cyclone separator according to this invention has an inner cyclinder and an outer cylinder defining an annular chamber therebetween, the outer cylinder comprising a plurality of tubes extending vertically in parallel relationship for at least a portion of their lengths, with the upper end portions thereof being bent inwardly to extend from the outer cylinder to the inner cylinder.
  • Means are provided for directing gases with entrained particulate material into the annular chamber for substantially circular movement therearound to enable separation of particulate material from these gases by centrifugal forces, with the separated material falling to the bottom of the separator and the gases discharging upwardly from the separator through the inner cylinder. Provision is also made for passing steam and/or water through the tubes to cool the outer cylinder. Normally, a portion of the tubes forming the outer cylinder of the separator are bent out of the plane of the outer cylinder wall to form an inlet opening for receiving the gases and directing same tangentiallly into the annular chamber. The upper end portions of the tubes can be extended to form an outlet chamber for said discharged gases.
  • the inwardly extending portions of the tubes forming the outer cylinder of a separator according to the invention can be attached to the inner cyliner to support same.
  • the inwardly extending tube portions can also be used to form a roof over the annular chamber.
  • the upper end portions of the tubes can in some embodiments extend inwardly to the inner cylinder and thereafter outwardly from the inner cylinder. In such a case, the outwardly extending tube portions, rather than the inwardly extending portions, may form a roof over the annular chamber.
  • each tube has a continuous fin extending from diametrically opposite portions thereof, each fin being aligned with a corresponding fin on an adjacent tube.
  • a continuous fin extends between adjacent tubes to form a gas-tight structure.
  • a cyclone separator according to the invention will normally include some refractory lining for the outer cylinder.
  • a refractory material extends around the inner and outer surfaces of the outer cylinder.
  • a refractory material extnds around the inner surface of the outer cylinder and insulation, possibly of another material, around the outer surface thereof.
  • the means for passing steam and/or water through the tubes of the outer cylinder may take a number of formed.
  • One such means comprises a ring header connected to the lower ends of the tubes, with an hopper extends downwardly from the ring header for receiving the separated particulate material.
  • Another suitable means comprises a first ring header connected to the upper ends of the tubes and a second ring header connected to the lower ends of the tubes, from which an hopper may depend.
  • upper and lower end portions of the tubes of the outer cylinder may be configured to form two opposite side walls of enclosures respectively above and below the outer cylind4er which thus comprises intermediate portions of the tubes.
  • Another optional feature is the provision of a plurality of support tubes connected to the outer cylinder for supporting the separator relative to a building.
  • the bulk, weight, cost of separators of the invention can be much less than that of conventional separators.
  • a separator roof-type circuit is not necessarily required.
  • the need for expensive high temperature refractor-lined ductwork and expansion joints between the furnace and the cyclone separator and between the latter and the heat recovery section can be substantially reduced or eliminated.
  • a cyclone separator of the invention can be put into use relatively quickly without any significant warm-up period. Additionally, the temperature of the outer walls of the separator can be maintained the same as the temperature of the walls of the adjoining reactor.
  • the reference numeral 10 refers in general to the cyclone separator of the first embodiment which includes a front header 12 and a rear header 14 forming the lower end portion of a side wall 16 of the separator.
  • a front header 18 and a rear header 20 form the lower end portion of the other side wall 22 of the separator.
  • the headers 12, 14, 18 and 20 extend to either side of a hopper 21 disposed at the lower portion of the separator for reasons to be described.
  • a group of vertically extending spaced parallel tubes 24 are connected at their lower ends to the header 12 and form the front portion of the wall 16, and another group of vertically extending spaced parallel tubes 26 are connected to the header 14 and form the rear portion of the wall 16.
  • a group of vertically extending spaced parallel tubes 28 are connected to the header 18 and form the front portion of the wall 22, and another group of vertically extending spaced parallel tubes 30 extend from the header 20 and form the rear portion of the wall 22.
  • the groups of tubes 24, 26, 28 and 30 extend vertically upwardly for a relatively small length and then are bent inwardly and angularly so that they together form a closed right cylinder shown in general by the reference number 32, with the tubes 24 and 28 together forming the front half of the cylinder 32 and the tubes 26 and 30 together forming the rear half of the cylinder 32.
  • a portion of the tubes 24 and 28 are bent out of the plane of the cylinder 32 as shown by the reference numeral 24a and 28a to form an inlet passage to the interior of the cylinder for reasons that will be described.
  • the tubes 24, 26, 28 and 30 are bent radially inwardly, as shown by the reference numberal 36, and then upwardly, as shown by the reference numeral 38, to define a circular opening which, of course, is of a diameter less than that of the diameter of the cylinder 32.
  • the tubes 24, 26, 28 and 30 are then bent radially outwardly as shown by the reference numeral 44 and then vertically upwardly as shown by the reference numeral 46.
  • the upper end portions of the tube group 26 thus form a sidewall which is connected to an upper header 48 and the upper end portions of the tube group 30 form a sidewall which is connected to an upper header 50.
  • the upper end portions of the tubes 24 and 28 are bent horizontally to extend across the upper end portion of the cylinder 32 to form a roof 52 and are connected at their free ends to upper headers 54 and 56, respectively. A portion of the upper portions of the tubes 24 and 26 have been deleted for the convenience of presentation.
  • tubes 24, 26, 28 and 30 do not bend in the manner discussed above but rather extend vertically for the entire length of the cylinder 32 for the purpose of enabling the separator to be supported from the roof of a building or structure in which the separator 10 is located.
  • These latter tubes are shown by the reference numeral 60 and extend from the header 18 in the manner discussed above, then straight up for the length of the cylinder 32 before bending horizontally to form a portion of the roof 52.
  • a plurality of lugs, or the like are connected to the tubes 60 and are adapted to tbe connected to hangers, or the like (not shown), which extend from the roof of the building to support the separator 10 without the need for steel supports at the bottom of the cylinders. It is also understood that the tubes 60 can be spaced out over the entire diameter of the cylinder 32, as needed.
  • An inner pipe, or barrel 61 is disposed within the cylinder 32 and is formed from a solid, metallic material such as stainless steel, and has an upper end portion extending approximately flush with the opening formed by the vertical bent tube portions 38.
  • the pipe 61 extends from the latter opening to an area coincidental with the inlet formed by the bent tube groups 24a and 28a.
  • annular passage is formed between the outer surface of the pipe 61 and the inner surface of the cylinder 32, for reasons that will be described.
  • each tube 24 has a pair of fins 62 and 64 extending from diametrically opposed portions of its wall, with a slight spacing being provided between the fin 62 of one tube and the fin 64 of an adjacent tube.
  • a seal plate 66 is provided in a slightly spaced relationship to the plane of the tubes 24 and a heat insulative refractory material is disposed between the outer surface of the tubes and the inner wall of the seal plate.
  • a plurality of tiles 70 extend adjacent the inner wall of the tubes 24 and are interlocked to protect the tubes from erosion.
  • the separator 10 In operation, and assuming the separator 10 is part of a boiler system including a fluidized bed reactor, or the like, disposed adjacent the separator, the inlet formed by the bent tubes 24a and 28a receives hot gases from the reactor which gases contain entrained fine solid particulate fuel material from the fluidized bed.
  • the gases containing the particulate material thus swirl around the annular chamber defined between the cylinder 32 and the inner pipe 61 and the solid particles are propelled by centrifugal forces against the inner wall of the cylinder 32 where they collect and fall downwardly by gravity into the hopper in a conventional manner.
  • the relatively clean gases in the annular chamber are prevented from flowing upwardly by the roof 52 and thus pass into and through the inner pipe 61 before exiting in a direction shown by the arrows in Figure 1 through an outlet defined by the sidewalls connected to the headers 48 and 50. It is understood that a plurality of screen tubes (not shown) can be provided in the path of the gases exiting in this manner and the gases can then pass to a heat recovery area disposed adjacent the separator 10.
  • Water from an external source is passed into the headers 12, 14, 18 and 20 and thus passes upwardly through the groups of tubes 24, 26, 28 and 30 before exiting, via the headers 48, 50, 54 and 56, to external circuitry which may form a portion of the boiler system including the separator 10.
  • each tube can be welded together to form a gas tight structure or, alternatively, can be eliminated and the tubes welded directly together.

  • tubes 120 are bent radially inwardly, as shown by the reference numeral 120b and then upwardly as shown by the reference numeral 120c, to define a circular opening which, of course, is of a diameter less than that of the diameter of the cylinder 122.
  • the tubes 120 are then bent radially outwardly as shown by the reference numeral 120d, and a portion of these bent tube portions 120d are bent upwardly as shown by the reference numeral 120e.
  • the best tube portions 120e form approximately one-half of a right circular cylinder 126.
  • bent tube portions 120d extend horizontally are bent at right angles in a horizontal plane, and then vertically, as shown by the reference numeral 120f, to form two vertically extending, spaced walls one of which is shown by the reference numeral 128.

  • the inlet passage 124 formed by the bent tube portions 120a receives hot gases from the reactor which gases contain entrained fine solid particulate fuel, ash, limestone, etc. from the fluidized bed.
  • gases containing the particulate material thus enter and swirl around in the annular chamber 134 defined between the cylinder 122 and the inner pipe 138, and the entrained solid particles are propelled by centrifugal forces against the inner wall of the cylinder 122 where they collect and fall downwardly by gravity into the hopper 116.
  • the relatively clean gases remaining in the annular chamber 134 are prevented from flowing upwardly by the roof formed by the tube portions 120b and their corresponding fins 140, and thus enter the pipe 138 through its lower end.
