Definitions

  • the invention relates to a method and a device for cooling a hot product gas, which contains sticky or molten particles which lose their stickiness when cooled, wherein an annular jet of a cooling fluid is injected into the hot product gas in a cooling zone with a circular cross-section, which is emitted from a A large number of separate cooling fluid jets with different levels of penetration is composed.
  • appropriate measures must therefore be taken to ensure that these accompanying substances do not impair the cooling and the downstream processing process through deposits on the walls of the apparatus used, on the heat exchanger surfaces and / or in the pipes.
  • Toroidal air heaters also work according to the same principle, in which cold air is mixed with the hot combustion gas in a mixing chamber.
  • this cooling principle for cooling hot product gases which contain sticky or molten particles, in particular for cooling partial oxidation gas.
  • the introduction of a cooling fluid through an annular gap is intended to prevent the particles from touching the wall and thus to eliminate the risk of deposits.
  • this goal cannot be achieved to a satisfactory extent.
  • the recirculation flow that forms at the edges of the frustoconical cooling fluid ring jet does not keep the sticky particles away from the wall, but on the contrary leads them to the wall.
  • the annular jet of the cooling fluid is composed of a plurality of separate cooling fluid jets with different penetration depths.
  • the cooling fluid is injected radially through openings in the wall of the cooling device which are connected to a ring line.
  • the penetration depth of the emerging cooling fluid jets can only be influenced by the different diameter of the openings. However, this should only be variable within a narrow range between 1.2: 1 and 1.5: 1.
  • the invention is therefore based on the object of improving this method of the type mentioned in such a way that contact with the wall of the sticky or molten particles is avoided during the cooling process and the risk of caking or deposits is thereby eliminated. At the same time, a complete and uniform mixing of product gas stream and cooling fluid is to be ensured, which is essential for uniform cooling of the product gas stream.
  • the method used to achieve this object is characterized in that the mass and penetration depth of the cooling fluid jets injected at an angle in the direction of flow of the product gas is adapted to the mass of the product gas stream flowing in the individual annular spaces of the cooling zone, the injection speeds of the cooling fluid jets being selected such that the desired penetration depths are achieved and the supply of the cooling fluid to the individual nozzle groups takes place via separate lines provided with valves.
  • the method according to the invention enables a bes This adjustable and variable penetration depth of the cooling fluid jets.
  • the annular jet can be broken down into a large number of separate individual jets, some of which have different masses, some are different penetration depths and the same or some different injection angles.
  • the cooling fluid supply can thus be adapted to the mass of the product stream flowing in the individual annular spaces of the cooling zone, which is necessary for the uniform cooling of the product gas stream.
  • FIG. 1 shows a schematic representation of the section from the cooling zone 2 in which the nozzle ring 4 is located for an injection of the separate cooling fluid jets.
  • the diameter D of the cooling zone 2 is divided into four parts, for example.
  • the diameters 4 D, 2 D, 3 4 D and D therefore limit annular spaces with different base areas in the cooling zone, which is shown in the illustration by different hatching.
  • the percentage of the base areas of these annular spaces in the total area of the cooling zone is 6.25%, 18.75%, 31.25% and 43.75% from inside to outside. With a constant flow velocity of the product gas over the cross section of the cooling zone, these percentages also apply to the distribution of the total mass of the product gas over the different annular spaces of the cooling zone.
  • cooling fluid masses m1, m 2 , m 3 , m 4 with different penetration depths e 1 , e2, e3, e 4 are therefore injected into the individual annular spaces of the cooling zone.
  • the injection angle ⁇ can be the same or different for operational reasons.
  • the injection speeds of the cooling fluid are chosen so that the desired penetration depths are achieved.
  • the injection speeds are preferably selected at the same time so that when the desired penetration depth is reached, the vertical component of the jet center speed in the flow direction is equal to the speed of the overall flow.
  • the cooling of 12oo to 17oo ° C hot partial oxidation gas is a preferred area of application of the method according to the invention contain molten particles, for example metals, salts or ashes.
  • a partial stream of the cold, purified product gas can preferably be used as the cooling fluid.
  • other media such as e.g. Steam or, if necessary, preheated water.
  • FIG. 2 shows the upper part of the reactor 1, which is used to generate the product gas to be cooled, and the cooling zone 2 directly adjoining it.
  • the reactor 1 is concerned a gasification reactor with the features known per se. Since the generation of the respective product gas is not the subject of the present invention, there is no need to go into the structural details of the reactor 1 here.
  • the cooling zone 2 has a circular cross section. The product gas generated flows in the direction of arrow 3 from the bottom upwards from the reactor 1 into the cooling zone 2.
  • the cooling fluid is applied in three stages with different objectives and different effects.
  • the actual cooling of the product gas stream takes place through the cooling fluid jets which are injected into the gas via the nozzle ring 4.
  • the specific conditions of this cooling fluid addition have already been discussed above.
  • the different penetration depths of the individual cooling fluid jets, which are marked by the arrows 5, are achieved by different injection speeds. These are in turn achieved by different initial pressures in the chambers 6a, 6b and 6c, into which the nozzle ring 4 is divided in this case, and by different nozzle diameters.
  • the nozzle ring 4 has a number of nozzles corresponding to the number of cooling fluid jets required, which is not shown in the figure.
  • the nozzles are evenly distributed over the entire circumference of the nozzle ring 4.
  • the different cooling fluid masses are obtained from the different number of nozzles with the same diameter.
  • the individual cooling fluid jets can have a different injection angle.
  • This injection angle ⁇ can range between 0 ° and 90 ° lie.
  • the corresponding injection angles are achieved by a corresponding inclination of the nozzles on the nozzle ring 4.
  • the injection speeds of the cooling fluid at the nozzle ring 4 are between 1 m / s and 100 m / s.
  • the individual nozzles are each connected via the chambers 6a, 6b and 6c to the lines 7 through which the necessary cooling fluid is supplied, the required pressure being able to be set via the valves 8.
  • the pressure of the cooling fluid in the chambers 6a, 6b and 6c is controlled as a function of the gas temperature in the cooling zone 2.
  • the gas temperature determined by the temperature measuring device 22 is used via the pulse line 21 as a control variable for the actuator 23 of the valve 8, so that this valve can be opened or closed depending on the measured temperature.
  • This type of control is particularly appropriate when the product gas is only produced in a smaller amount than normal in part-load operation and therefore the cooling process is only operated with a reduced amount of cooling fluid. This can go so far that the cooling fluid supply to individual nozzle groups is completely interrupted.
  • the control described above has only been drawn for the chamber 6a of the nozzle ring 4. Of course, this regulation can also be applied to the other chambers.
  • a further cooling fluid stream is introduced into the device in the direction of the arrows 11 via the annular gap 10.
  • This cooling fluid flow is intended to keep the particles away from the reactor wall by displacement.
  • the transition region 9 is designed such that its change in inclination continuously changes into the cylindrical part of the cooling zone 2 after an exponential function.
  • the speed of the cooling fluid jet, which is injected via the annular gap 10 is in the range between 0.1 m / s and 50 m / s.
  • the annular gap 10 is preferably formed in that the wall 12 in the upper part of the reactor 1 is offset, as can be seen from the figure.
  • the annular gap 10 is connected via the line 13 to the ring line 14, which is supplied with the required cooling fluid via the line 15.
  • a further cooling fluid stream is also injected into the cooling zone 2 above the nozzle ring 4 via the annular gap 16.
  • This cooling fluid flow which is marked by the arrows 17, is intended to avoid or suppress eddies and backflows which may be generated by the injection of the cooling fluid via the nozzle ring 4 on the wall of the cooling zone 2.
  • the angle ⁇ is chosen to be correspondingly small, namely in the range between 0 ° and 45 °, so that this cooling fluid flow itself does not cause any backflow on the wall of the cooling zone 2.
  • the speed of the cooling fluid flow is in the range between 1 m / s and 50 m / s.
  • the annular gap 16 is in turn connected via line 18 to the ring line 19, which is supplied with the required cooling fluid via line 20.
  • FIG. 2 is only a schematic illustration of the device according to the invention, from which special structural configurations cannot be deduced.
  • the walls of the reactor 1 and / or the cooling zone 2 can be designed as tube walls through which a cooling medium flows and which are provided on the inside with a refractory lining.
  • the gap 16 can be given a different configuration for manufacturing reasons, which will be discussed further below in connection with FIG. 4.
  • FIG. 3 shows a cross section through another embodiment of the nozzle ring 4.
  • the nozzle ring in this case has two chambers 6a and 6b located one behind the other. While in the embodiment according to FIG. 2 the rows of nozzles of the individual chambers 6a, 6b and 6c lie one above the other, in the embodiment shown in FIG. 3 all the nozzles are in one plane.
  • the nozzles 24 assigned to the rear chamber 6a are each connected to this chamber via the line pieces 25, while the nozzles 26 assigned to the front chamber 6b are embedded directly in the chamber wall.
  • the nozzles 24 and 26 can have different diameters and / or angles of inclination. As a rule, the nozzles assigned to a nozzle chamber will each be the same.
  • FIG. 4 finally shows a longitudinal section through a special embodiment for the addition of cooling fluid above the nozzle ring 4. While in the device shown in FIG. 2 the cooling fluid is injected into the cooling zone 2 via the annular gap 16, it can be attached for manufacturing reasons. a nozzle ring 27 is also to be used for this.
  • the guide ring 29, which is open at the top, is placed on the nozzle ring 27, through which the cooling fluid jets emerging from the nozzles 28 are made more fluid.
