针对目前铁水镁脱硫喷枪结构单一及使用中枪体振动易引起气体逸出不均匀、喷溅较大等问题,通过水模型物理模拟和数值模拟,设计了一种汽化室带侧孔的新型脱硫喷枪。研究结果表明:设计喷枪喷吹时,气体从汽化室逸出连续均匀,气泡在液相中分布均匀弥散,且停留时间与原喷枪相当,液面波动较平稳均匀。工业试验结果表明:使用新型喷枪可降低镁耗23.3%,显著提高脱硫剂的利用率和脱硫效率。喷枪使用时喷溅较小,寿命与原喷枪相当。
Aiming at the problems of the single structure of magnesium desulphurization lance and the vibration of the gun body in use, the problem of gas escaped unevenly and large splashing is caused. A new type of desulphurization with side holes in vaporization chamber was designed by physical simulation and numerical simulation of water model. spray gun. The results show that when the spray gun is designed, the gas escapes continuously and evenly from the evaporation chamber, and the bubbles are uniformly dispersed in the liquid phase. The residence time is equivalent to that of the original spray gun, and the fluctuation of the liquid surface is stable and even. Industrial test results show that: the use of new spray gun can reduce the magnesium consumption of 23.3%, significantly improve the desulfurization agent utilization and desulfurization efficiency. Spray gun used when smaller, the same life as the original gun.
