Definitions

  • the invention relates to a reactor chamber door for large scale coking reactors with a double sealing system.
  • a furnace chamber closure for a horizontal chamber coking furnace which has a double sealing system.
  • This lock is a very complicated coke oven door with a rigid cast door body and heavy stone plugs connected to it. Compensation for temperature-related deformations of the chamber frame is only possible to a limited extent in the known door construction and the associated sealing systems.
  • the object of the invention is to propose a reactor chamber door which is also provided for large-scale coking reactors with an extremely large chamber volume and in which the problems listed do not occur.
  • the reactor chamber door consist of an outer and inner door, which are releasably connected and, if necessary, can be handled separately and each have their own circumferential door sealing system which can be pressed resiliently against the chamber frame.
  • the outer and inner doors are loosely connected to one another, so that one of the two doors can be replaced in a simple manner for the purpose of maintenance and repair.
  • the outer and inner door each have their own door sealing system with their own resilient pressure against the chamber frame.
  • the outer and inner doors can be connected to one another via interlocking supporting claws and supporting beams in such a way that supporting claws arranged on the inside of the outer door engage under supporting beams arranged on the outside of the inner door.
  • This construction is comparable to the door lifting devices in conventional coke oven doors. It has the advantage that the outer and inner doors can be inserted or removed together in the door openings of the reactor chamber.
  • the inner door is not attached to the chamber frame suspended and the pressure forces acting on the door stopper from the contents of the reactor chamber are transmitted into the support frame of the outer door via stopper holders, door contact surfaces between the inner and outer door, possibly spacers and / or set screws.
  • the inner door consists of a hot membrane covering the entire door opening, which can be pressed resiliently from the outside against the chamber frame. It is a metal-to-metal seal located in the hot area. Because of the high temperatures, there is still no formation of tar condensate at this point, so that this seal is largely maintenance-free.
  • leaf springs which are adjustably attached to the support structure, are used, which press the hot membrane from the outside against the chamber frame.
  • the door sealing system on the outer door consists of a membrane covering the entire door opening with a circumferential seal which can be pressed resiliently against the chamber frame, preferably a soft seal designed as a full profile or as a hose. It has been shown that in the double sealing system according to the invention, these outer soft seals are not contaminated with tar approaches and also remain sufficiently elastic.
  • Insulation can be arranged on the inside of the membrane of the outer door to prevent heat loss. Spacers are expediently arranged in this insulation in order to transmit the forces from the contents of the reactor chamber to the set screws fastened to the support frame.
  • the seals on the outer door can, according to the invention, similarly to those on the inner door, be pressed against the chamber frame with the aid of leaf springs which are individually or group-wise attached to the supporting frame of the outer door, preferably in the longitudinal direction of the reactor chamber.
  • the distance between the support structure and the membrane on the outer door can be changed with the aid of set screws.
  • the intermediate space between the outer membrane or the insulation attached to the membrane and the inner hot membrane and the chamber frame can, according to the invention, be acted upon with a sealing gas, in particular inert gas, and thus be kept under excess pressure to avoid raw gas leaks.
  • a sealing gas in particular inert gas
  • the sealing system of the inner door can come to rest on the inner chamber frame and the sealing system of the outer door on the outer chamber frame.
  • the door stopper with a trapezoidal frame, the side surfaces of which form cones, the conically shaped chamber walls in the entrance area of the reactor chamber can be assigned.
  • the reactor chamber door consists of a support frame 1 which extends over the entire door height and has two or more locks 3 designed as a spindle or spring which engage in the locking hooks 30 after the door has been inserted into the door opening of the reactor chamber 29.
  • the support frame 1 consists of two vertical U-profiles.
  • Door guides 32 are fastened to the outside of these U-profiles and slide along the inside of the locking hooks 30 when the door is inserted.
  • the so-called outer door also consists of the outer membrane 8, the distance from the support frame 1 with the adjusting screws 2 can be changed even during operation.
  • Exchangeable soft seals 9, 10 are arranged on the membrane in the outer circumference in a U-shaped holder and are pressed against the sealing surface on the outer chamber frame 24 by means of the leaf springs 4, 4a.
  • the circumferential angular lateral leaf springs 4 are attached to the support frame 1 by means of the screws 6. To compensate for unevenness, the distance between the end of the leaf springs 4 and the outer membrane 8 is changed using the screws 5.
  • the leaf springs 4a are Z-shaped and fastened to the support frame 1 with the aid of clamping plates 36 and adjusting screws 37 known per se in the longitudinal direction of the chamber.
  • the circumferential soft seal is shown as a full profile 9 and in Figure 2 as a hose 10.
  • the outer door also includes the insulation 11 arranged on the inside of the outer membrane 8 with spacers arranged therein and the door contact surfaces 12 assigned to the inner door.
  • the carrying claws 13 are also connected to the supporting frame 1, which grip under the supporting beam 14 for transporting the inner door.
  • the inner door consists of the two vertical U-bars 15 with the horizontal support beams 14, the peripheral leaf springs 16 attached to the U-bars 15, the free ends of which press the edges of the hot membranes 17 against the inner chamber frame 25.
  • the plug holders 18, which are designed as hooks and which engage in hanging pockets 22 of the door plug 19, are firmly screwed to the U-bars 15 and the hot membrane 17.
  • the door plug consists of an outer U-shaped frame 20 made of refractory material or heat-resistant steel and the inner insulation 21.
  • a circumferential, replaceable sealing cord is provided in the frame 20 on the outside 31 provided.
  • a sealing gas in particular inert gas, can be fed into the intermediate space 23 between the inner membrane 17 and the outer membrane 8 or the insulation 21, which is optionally kept under excess pressure.
  • the two chamber frames 24 and 25 form a unit with the wall protection plate 26 and together with the anchor stands 27 the anchoring for the reactor heating wall 28.
  • the two chamber frames are designed as thin rectangular or angular profiles and are optionally with the interposition of insulation from the outside in front of the wall protection plate 26. If necessary, they can be replaced individually.
  • the soft seals 9, 10 come to rest on the outer chamber frame 24 and the outer edge of the hot membrane 10 on the inner chamber frame 25.
  • the temperature at the inner seal between the chamber frame 25 and the membrane 17 will be so high that tar condensate formation and thus cleaning at the sealing point will be avoided.
  • the pressure exerted by the furnace batch in the reactor chamber 29, in particular in the case of hot coal charging, on the door stopper 19 is via the stopper parts 20, 21, the hanging pockets 22, the stopper holder 18, the U-iron 15, the door contact surfaces 12, the spacer 7 and the Transfer the set screws 2 directly into the support frame 1 and via the locks 3 into the locking hooks 30.
  • the reactor chamber door is not guided via door guides 32, but via guide elements 34, each of which has a cylindrical or, if appropriate, also a conical bore 35 and into which guide mandrels 33 are inserted when the reactor chamber door is retracted, which are fastened to the wall protection plates 26 .
  • the reactor chamber 29 has a conical chamber wall 38 in the entrance area. Accordingly, the door stopper 19 in this example is provided with a trapezoidal frame 40, the side walls 39 of which form cones. With this configuration, insertion and removal of the reactor chamber door are facilitated.
