Sulfur ejector 60, before work, is attached by ring flange 68, to be fixed on sulfur burner 80 by sulfur ejector 60 by sulfur ejector 60 with sulfur burner 80.Time fixing, the ejiction opening 674 of sulfur ejector 60 need to be made to be arranged in sulfur burner 80, and pump orifice 629 is positioned at outside sulfur burner 80.Starting compressor 22, the air of suction is compressed by compressor 22, and compression air is heated by air heat switch 24, so that air converts the injection air with certain pressure intensity and temperature to.Injection air enters shower nozzle 648 from air inlet pipe 646.The pressure energy of injection air is converted into kinetic energy by the injection channel 644 of shower nozzle 648, and now, the pressure of injection air reduces, and speed increases.Injection air is sprayed by jet 645, and liquid-state sulfur is drawn in suction chamber 628 via pump orifice 629 by the Involving velocity of high velocity air from sulfur melting groove 40.Injection air and liquid-state sulfur form mixed atomizing after being sufficiently mixed in hybrid chamber 6722 and discharge nozzle throat 6724, and spray in sulfur burner 80 from ejiction opening 674 via diffusion chamber 6726.The mixed atomizing of injection air and liquid-state sulfur is lighted in sulfur burner 80, and to generate sulfur dioxide gas, sulfur dioxide is used for refining sugar by subsequent technique.In the process of sulfur ejector 60 work, it is sheathed on the confession warmware 69 on suction tube 62 and discharge nozzle 67 to sulfur ejector 60 heat supply, to guarantee that the liquid-state sulfur being positioned at sulfur ejector 60 has preferably mobility smoothly arrival ejiction opening 674.
Sulfur ejector 60 is operationally, it is necessary to adjusts the jet 645 larynx mouth with mixing tube throat from L, or adjusts the cross-sectional area ratio of discharge nozzle throat 6724 and jet 645.In the present embodiment, when needing to reduce larynx mouth from L to strengthen when entrainmenting intensity of high velocity air, the air inlet pipe 646 that only need to turn clockwise makes air inlet pipe 646 move towards discharge nozzle 67, and now, the numerical value that rotating cycle × pitch obtains is exactly that larynx mouth is from the L distance shortened；Otherwise, if needing to expand larynx mouth from L to reduce when entrainmenting intensity of high velocity air, then rotating counterclockwise into trachea 646 makes air inlet pipe 646 move towards the direction away from discharge nozzle 67, and now, the numerical value that rotating cycle × pitch obtains is exactly that larynx mouth is from the L distance expanded.
In the present embodiment, the adjustment of discharge nozzle throat 6724 and the cross-sectional area ratio of jet 645, realized by replacing discharge nozzle 67.Owing to discharge nozzle 67 and suction tube 62 are threaded connection, it is possible to be convenient for changing discharge nozzle 67, to change the cross-sectional area of discharge nozzle throat 6724, and change the cross-sectional area ratio of discharge nozzle throat 6724 and jet 645 accordingly.Owing to the cross-sectional area ratio of discharge nozzle throat 6724 with jet 645 affects the suction volume of liquid-state sulfur, therefore, by regulating the discharge nozzle throat 6724 cross-sectional area with jet 645 than the suction volume that can control liquid-state sulfur well, and then ensure the quality of sulfur burning and the growing amount of sulfur dioxide.
It is appreciated that and is optionally set on suction tube 62 or discharge nozzle 67 also dependent on being actually needed for warmware 69.
In another embodiment, heat tracing pipe 694 is the pipeline of a hollow, and it is for passing through for steam, with to suction tube 62 and/or discharge nozzle 67 heat supply.
In another embodiment, sulfur ejector 100 is also arranged with couveuse (not shown).Described couveuse is used for passing into high-temperature steam, it is simple to control the temperature of fluid in sulfur ejector 100 so that in sulfur ejector, bulk temperature is uniform.Preferably, heat-insulation layer (not shown) can be also provided with inside and outside this couveuse.
Described above is the detailed description for the present invention preferably possible embodiments, but embodiment is not limited to the patent claim of the present invention, the equal change completed under technical spirit suggested by all present invention or modification are changed, and all should belong to the contained the scope of the claims of the present invention.
