针对目前我国正在运行四种再生橡胶脱硫技术工艺,我将进行简要的分析评价。一、二氧化碳高压脱硫技术工艺、工业设计:二氧化碳高压脱硫技术,采用干冰在7-14mpa压力下打断S键。颗粒橡胶门尼小于80,物料流动很重要,在10mpa工作压力状态时,搅拌装置和密封装置设计难度较大,因此形成工业化规模生产, In view of the four kinds of regenerated rubber desulfurization technologies currently running in our country, I will conduct a brief analysis and evaluation. First, the high-pressure carbon dioxide desulfurization technology, industrial design: carbon dioxide high-pressure desulfurization technology, the use of dry ice pressure in the 7-14mpa interrupted S key. Particle rubber Mooney is less than 80, material flow is very important at 10mpa working pressure state, the stirring device and sealing device design more difficult, so the formation of industrial-scale production,
