Definitions

  • the tubes 14 are spaced apart by a plurality of fins 16 extending from diametrically opposed portions of each tube for the entire length of the tubes and connected to the tubes in any conventional manner, such as welding, to render the separator 2 gas-tight.
  • the width of each fin 16 is constant in the cylindrical section 6, with the exception of the inlet opening 6a, and varies in the roof section 4 and the hopper section 8 as will be described.
  • the separator 40 includes a cylindrical section 42 and a conically-shaped lower hopper section 44.
  • the cylindrical section 42 and an upper part of the hopper section 44 are formed by a group of continuous, spaced, constant diameter, parallel tubes 46.
  • the tubes 46 are spaced apart by a plurality of fins 48 extending from diametrically opposed portions of each tube and connected to the tube in any conventional manner, such as welding.
  • the width of fins 48 necessarily decreases from top to bottom in the conically-shaped hopper section 44 until adjacent tubes are in direct contact with one another negating the need for a fin.

Claims (4)

  1. Ein Zyklonabscheider, umfassend einen Innenzylinder (36), eine Mehrzahl von Rohren (14, 44) mit Segmenten, die sich senkrecht in paralleler Beziehung zueinander erstrecken, so daß sie einen Außenzylinder (6, 42) bilden, der sich koaxial um den Innenzylinder (36) erstreckt, was zur Folge hat, daß zwischen den Zylindern eine Ringkammer abgegrenzt wird, wahrend andere Rohrsegmente (14, 44) einwärts gebogen sind, so daß sie einen kegelförmigen Trichterabschnitt (8, 44) bilden, der sich unterhalb des Außenzylinders (6, 42) erstreckt, Mittel zum Umwälzen von Flüssigkeit durch die Rohre einschließlich eines einzigen unteren Ringsammlers (10, 50), an den die unteren Enden aller der Rohre (14, 46) angeschlossen sind, und Mittel (6a) zum Richten von feste Teilchen enthaltenden Gasen durch die Ringkammer, um die festen Teilchen durch Zentrifugalkräfte von den Gasen zu scheiden, wobei die abgeschiedenen Gase aus dem Innenzylinder (36) austreten und die abgeschiedenen Feststoffe zwecks Beseitigung oder Wiederaufbereitung in den Boden des Trichterabschnitts (8, 44) fallen, dadurch gekennzeichnet, daß entweder ein Teil der Rohre (14) in mindestens einem Bereich aus der Wand des Trichterabschnitts (8) entnommen wird, so daß die restlichen Rohre (14) den Trichterabschnitt (8) über den Bereich hinaus verlängern, in dem jedes der Rohre (14) mit den daran anschließenden Rohren in Kontakt käme, wenn keines der Rohre entnommen wäre, oder mindestens ein Teil der den Trichterabschnitt (44) bildenden Rohre (46) in mindestens einem Bereich gestaucht ist, um den Durchmesser der Rohre (46) zu verringern und somit die Länge des Trichterabschnitts über den Bereich hinaus zu verlängern, in dem jedes der Rohre (46) mit den daran anschließenden Rohren in Kontakt käme, wenn keines der Rohre gestaucht wäre.
  2. Ein Abscheider nach Anspruch 1, bei dem die Mittel zum Umwälzen von Flüssigkeit durch die Rohre einen oberen Ringsammler (12) umfassen, der mit dem oberen Enden der Rohre (14, 46) in Verbindung steht, sowie den unteren Ringsammler (10, 50), der mit den unteren Enden der Rohre in Verbindung steht, und Mittel zum Hindurchleiten von Wasser, Wasserdampf bzw. einem Gemisch aus Wasser und Wasserdampf durch die Ringsammler (12, 10, 50), um das Wasser, den Wasserdampf bzw. das Gemisch aus Wasser und Wasserdampf zwecks Kühlung des Abscheiders durch die Rohre (14, 46) umzuwälzen.
  3. Ein Abscheider nach einem der vorstehenden Ansprüche, bei dem die oberen Rohrsegmente (16, 46) einwärts gebogen sind, so daß sie einen Dachabschnitt (4) bilden.
  4. Ein Abscheider nach einem der vorstehenden Ansprüche, bei dem die aneinander anschließenden Rohre (14, 46) durch eine Vielzahl von Rippen miteinander verbunden sind, um den Abscheider gasdicht zu machen.
