Definitions

  • the invention relates to a hot gas cooling system for a coal gasification system with the features of the preamble of claim 1.
  • a hot gas cooling system of this type is known from US Pat. No. 4,328,007.
  • the gas outlet line penetrates the cylindrical wall of the pressure vessel of the convection cooling device with a straight section and then leads with a bent section to a channel within the pressure vessel containing the convection heating surfaces.
  • the disadvantage of this design is that the gas outlet line cannot be dismantled because the majority of it runs inside the pressure vessel.
  • the gas outlet line is not cooled, so that the upper temperature of the gas leaving the radiation cooling device is limited.
  • the invention has for its object to improve a hot gas cooling system of the type mentioned in a structurally simple manner so that the gas outlet line can be cooled and easily dismantled together with a cooling device.
  • this object is achieved by the features of the characterizing part of claim 1.
  • This design of the gas outlet line means that it is fully accessible at all times along its entire length and can be Dismantle together with the pipe body in a simple manner by loosening the flange connections. In this way, any maintenance work in the convection cooling device is made considerably easier, provided that it is carried out from above. Furthermore, because of the cooling tube body, the temperature of the gas leaving the radiation cooling device can be higher than in the gas outlet line of the known cooling system.
  • the hot gas cooling system essentially consists of a radiation cooling device 1 and a convection cooling device 2, only the upper part of which is shown.
  • the radiation cooling device 1 has a cylindrical pressure vessel 3, which is penetrated at its upper end by a gas supply channel 4, which is connected to a coal gasification reactor, not shown.
  • an insert 42 is provided in the latter, which is formed from vertical, closely adjacent tubes 50 and which surrounds a first gas duct 5 through which the hot gas flows from top to bottom.
  • the insert 42 is surrounded by a shirt 43, which is also formed from vertical tubes which are welded together in the manner of a membrane wall.
  • the shirt 43 surrounds the insert 42 at a distance, so that an annular space remains between them, through which the gas flows from bottom to top and forms a second throttle cable 6.
  • the tubes of the insert 42 and the shirt 43 are connected at their lower and upper ends to ring collectors 7 and 8, respectively.
  • a coolant e.g. Water supplied, which evaporates when flowing through the tubes and is discharged from the upper collector 8 via a line 10.
  • the tubes of the insert 42 and the shirt 43 are suspended near their upper end on a support system consisting of profile supports 11, so that they can freely expand downwards.
  • a funnel 12 which tapers downwards and penetrates the bottom of the pressure vessel 3 and which is partly filled with water and serves to collect ash and slag particles which are carried by the hot gas stream and when it is deflected from the first gas train 5 into the second gas train 6 be thrown out.
  • the convection cooling device 2 likewise has a pressure vessel 15 with a vertical axis and a plurality of cooling tube bundles 13 are arranged in the interior thereof, only one of which is shown in FIG. 1.
  • the pressure vessel 15 is closed at the top by a cover 16 which is detachably connected to the pressure vessel 15 via a flange connection 17.
  • the two adjacent pressure vessels 3 and 15 are supported in their upper area by claws 19 and 20 on a common foundation 18.
  • a radial gas outlet connection 30 is connected to the pressure vessel 3, which tapers conically and has a flange 29 at its tapered end.
  • the tubes of the shirt 43 are bent outward in the manner of a loop in such a way that they cover the inner surface of the connector and the flange.
  • the gas flow is calmed by the conical shape of the nozzle 30.
  • a connecting line 26 Connected to the flange 29 is a connecting line 26, which here has the shape of a 90 ° elbow and which is provided at both ends with a flange 27 and 28, respectively.
  • the flange 27 is detachably connected to the flange 29 by screws, not shown.
  • the flange 28 is opposite a flange 32 which is connected to the cover 16 of the Pressure vessel 15 is attached and which is also releasably connected to the flange 28 by means of several screws.
  • the flanges 27 and 29 on the one hand and 28 and 32 on the other hand are therefore at right angles to one another.
  • a line 25 guiding the gas flow which begins at the flange 27 and penetrates the cover 16 in a 90 ° bend from above and projects into the interior of the pressure vessel 15. Thanks to the detachable flange connections, the connecting line 26 can be removed from the pressure vessels 3 and 15 together with the gas guide line 25.
  • the gas guide line 25 from the flange 27 to its end projecting into the interior of the pressure vessel 15 is designed as a cooled line.
  • the line 25 consists of a number, for example sixteen, of tubes 35 bent in accordance with the course of the line, which are connected at their upper end to a ring collector 36 and at their lower end to a ring collector 37. Pipes 35 lying next to one another are welded to one another via interposed webs 38, so that they form a coherent curved body.
  • the tube 35 bent with the smallest radius of curvature is connected to a coolant supply pipe 39 which is arranged radially and penetrates the connecting line 26.
  • the ring collector 36 is divided into two spaces by two partitions, in such a way that five tubes 35 lying on the inside of the bend in FIG. 2 are connected to one space of the collector, while the other eleven tubes 35 located on the outside of the bend are connected to the second Collector room are connected.
  • the tube 35 with the largest radius of curvature has a radial coolant discharge pipe 39 ', which the Connecting line 26 penetrates. In this way, a natural circulation of the coolant results in that the coolant supplied via the pipe 39 flows downwards in the five pipes 35 on the inside of the curve and then flows upwards after collection and distribution in the collector 37 in the eleven pipes 35 on the outside of the curve, after which heated coolant is discharged via the pipe 39 '.
  • the coolant flowing in the pipe 39 divides at the junction with the pipe 35 into two partial flows, one of which flows directly into the downward section of this pipe, whereas the other partial flow flows to the ring collector 36 and is distributed there to the remaining four downpipes .
  • two coolant partial flows come together in the discharge pipe 39 ', namely an upward flowing partial flow in the pipe 35 with the largest radius of curvature and a partial flow from the other riser pipes, which reaches the pipe 39' via the upper space of the ring collector 36.
  • the ring collector 36 is connected to the flange 27 of the connecting line 26 via a compensator 40.
  • a plurality of radial support plates 41 are welded over the length of the line 25 and, in the assembled state, rest on the inner surface of the connecting line 26.
  • the penetration point of the feed pipe 39 and the discharge pipe 39 'on the connecting line 26 can be designed as a flexible, tight connection, e.g. in the form of so-called thermosleeves.
  • a tab 14 is provided between the two pressure vessels 3 and 15, which is articulated with two mutually opposite claws 19 and 20 is connected.
  • the tab 14 absorbs horizontal forces acting on the pressure vessels and thus relieves the connecting line 26 of these forces. If the distance between the pressure vessels 3 and 15 should be drawn larger than in Fig. 1, a straight pipe section can be inserted between the flanges 27 and 29, the tab 14 being dimensioned correspondingly longer. In such a case, it may be advisable to make the tab 14 hollow and to switch it into the coolant circuit which circulates in the gas guide line 25.
  • this line can also consist of a curved tube with a smooth inside and tubes flowed through with coolant on the outside thereof.
  • a smooth inside of the gas conduction line is also obtained if the line is welded together from known ⁇ tubes through which coolant flows.
