Method for directly injecting liquid sulfur into fuming furnace for vulcanization and volatilization

The invention discloses a method for directly injecting liquid sulfur into a fuming furnace to be vulcanized and volatilized, which can ensure that a vulcanizing agent liquid sulfur pipeline is smoothly conveyed and is not blocked, the feeding speed of the liquid sulfur is accurately controlled, and the technical problems of waste caused by direct combustion of granular sulfur and easy blockage of the pipeline caused by direct injection of the granular sulfur are solved. Due to the arrangement of reasonable positions of particle sulfur and pulverized coal burners of the fuming furnace, the vulcanization-reduction combined reaction is ensured to be fully carried out, and the control of optimal economic indexes of liquid sulfur and pulverized coal is realized. 本发明公开了一种液态硫磺直接喷射入烟化炉内硫化挥发的方法，该方法可以确保硫化剂液态硫磺的管道输送顺畅、不堵塞，液态硫磺给料速度的准备控制，避免颗粒硫磺直接燃烧的浪费和颗粒硫磺直接喷射易堵塞管道的技术难题，烟化炉颗粒硫磺与粉煤烧嘴合理位置的设置，确保硫化-还原联合反应的充分进行，实现液态硫磺与粉煤的最佳经济指标的控制。
