Below with reference to the narration of accompanying drawing the method for using the principle of the invention has been described, in any case but can not be interpreted as and limit the scope of the present invention.
Refer now to Fig. 1-4 and be described more specifically burner nozzle 10 and 30.Burner nozzle 10 comprises, a center conduit that forms passage 4; A second annular concentric conduit that forms circular channel 5; With the 3rd an annular concentric conduit 3 that forms circular channel 6.By spacer 17 passage 5 and passage 4 and 6 are kept the relation that separates each other.It should be minimum that spacer takes up space, and causes unnecessary separation to avoid slurry stream mobile in the passage 5. Passage 4,5 and 6 is sealed by wall 7a, 7b and 7c in their end, upstream, wherein provides inlet pipe 15 and 16 for slurry and gas incoming flow, a distribution chamber 18 is set, so that equably slurry feed stream is sent into circular channel 5.Passage 4,5 and the 6 formed downstream ends in end in them and conduit 1,2 and 3 have discharge outlet 8a, 8b and 8c.Pipe 19 provides connected channel between passage 4 and 6 for the delivering gas incoming flow.
Burner nozzle 10 also comprises a blast atomizer, and it has one for spraying the convergence plane 9a that the slurry pass passage 5 is used, and comprises that also an elongated outlet opening 11 is so that send into reactor to the mixture of slurry and oxygen-containing gas with pick up speed.Spraying gun 9 is extensions of conduit 3 in this embodiment.Because spraying gun 9 is subjected to rigorous environment, be high temperature, chemical erosion, and mechanical wear, even be not essential, it also is favourable making spraying gun by strong, the tough and tensile and attrition resistant material of for example erosion resistance (for example wolfram varbide and silicon carbide), and the rest part of nozzle 10 can be by making like an elephant the such metal of stainless steel.It also is favourable that a water jacket that has water inlet pipe 13 and rising pipe 14 is set, so that the wall 11a in cooling spraying gun 9 and hole 11.The hole 11 of nozzle 10 is designed to cylindrical, but the wall 11a of dispersive or convergence also can be arranged.In addition, though be not the strict design requirement, the length in hole 11 is greatly favourable than its diameter, can reach the high atomization degree the extra time is provided for slurry/gaseous mixture with for being transported to this mixture in the reactor in high-shear region like this.
With reference to figure 3 and 4 another embodiment of the invention is described.Reference symbol at each element of the burner nozzle 30 shown in Fig. 3 and 4 is similar to the reference symbol of element shown in the burner nozzle 10 among Fig. 1 and 2, and they have identical referential data.Burner nozzle 30 comprises therefore central authorities and improvement second annular pipe is changed central gas channel and slurry passage, also comprises the remodeling to nozzle atomization device and outlet opening.So burner nozzle 30 comprises annular pipe section 31a and 31b and forms the circular channel that has the first circulation section 32a and second section 32b.The cross section of the first circulation section 32a is bigger significantly than the cross section of the second circulation section 32b.Directly be admitted to the first circulation section 32a from the slurry feed stream of inlet pipe 15, can save the flue 19 of jet hole like this, and allow gas feed stream flow directly into passage 4 and 6.Slurry is flowed in passage circulation section 32a and 32b to significantly reduce separating of occurring.If necessary, can add fastening piece 34, to overcome any structure undercapacity.
As previously mentioned, handling the issuable problem of being made up of finely divided solids of highly enriched slurry in like an elephant the ring nozzle of burner nozzle 10 and 30 is that finely divided solids separates with liquid vehicle, and stops up the slurry passage.In order to overcome the possibility that this situation occurs, and for evenly flowing on the entire cross section that reaches the annular flow passage, settled distribution chamber 18 in the nozzle 10, and nozzle 30 comprises and unites circulation section 32a and 32b, they have formed the slurry passage.In nozzle 10 and 30, the cross-sectional area of the upstream distribution chamber in slurry stream road or circulation section is bigger significantly than the cross-sectional area of downstream circulation section.As an object lesson, resembling the nozzle that designs the nozzle 30 is made by metal tube, wherein the diameter of central gas channel is approximately 7.6cm, long 40.6cm, and wide around first section annular cross section of the slurry passage of centre gangway is about 3.8cm, long 10cm, second annular cross section of slurry passage is wide to be about 0.6cm, long 30.5cm.
On the whole upstream circulation section annulus area of upstream circulation section and the annular section connection, downstream of passage, slurry stream in big upstream chamber or the section provides a basic pressure uniformly, and therefore the fluctuations in discharge around the annular channels of slurry stream significantly reduces.Also find, the upstream portion of the slurry passage that interconnects by the annular section of design from the downstream inlet tube to passage, can remain on the place of interconnecting substantially even annular pressure is arranged, like this, pressure falls and is approximately 20%, and the pressure that is occurred in the annular section of its discharge outlet at slurry downstream slurry passage falls littler than this.
For the mixture that makes slurry and gas reaches desirable homodisperse and atomizing, determine that the favor speed that gas and slurry stream are crossed each passage should remain on following scope.The outlet discharge rate of the gas stream by central axial passage should be about 23 meter per seconds to about velocity of sound.The outlet discharge rate of the gas stream by the exterior annular passage should be about 23 meter per seconds to about velocity of sound.By second or the outlet discharging of the slurry of intermediate annular passage stream should be about 0.3-15 meter per second.The speed that enters the mixture of the slurry of reactor and gas by the jet exit hole should be that about 30 meter per seconds are to about velocity of sound.
