Abstract:

Existing domestic sulfur wet granulation technology has problems such as small processing capacity, low efficiency, irregular product shape, high fine powder rate, dispersed control and complex operation. A new type of sulfur forming module, micro - positive - pressure inert closed - type vibrating screen system, sulfur particle liquid - phase forming pre - crystallization facility, and sulfur liquid - phase granulation sequence control system were developed. An environmentally friendly, efficient, energy - saving, and centrally controlled high - throughput energy - efficient sulfur underwater granulation system was developed, and a test platform was built for experimental verification. Industrial application was carried out in a refining and chemical enterprise. The results show that the system has a large processing capacity of 100 t/h. The sulfur particle size qualification rate is not lower than 99.9%, and the moisture content is not higher than 0.5%. Compared with existing domestic products of the same scale, the consumption of circulating cooling water can be reduced by about 33%, the consumption of demineralized water can be reduced by about 33%, the power consumption can be reduced by about 24%, and the consumption of low - pressure steam can be reduced by about 12%. The overall technology of the system meets the requirements of large - scale sulfur recovery devices and environmental protection emissions, and is worthy of promotion and application.

摘要：

现有国产硫磺湿法造粒技术存在处理量较小、效率低、产品外形不规则、细粉率高、控制分散、操作复杂等问题。研发了新型硫磺成型模块、微正压惰化密闭振动筛系统、硫磺颗粒液下成型预结晶设施、硫磺液下造粒顺序控制系统等，开发了环保、高效、节能、可集中控制的大处理量高效节能型硫磺液下造粒系统，并搭建了试验平台，进行了试验验证。在某炼化企业进行了工业应用，结果表明：系统处理量大，为100 t/h；硫磺粒径合格率不低于99.9%，含水率不高于0.5%；相较于国内现有同类产品，在同等规模下，循环冷却水消耗量可降低约33%，除盐水消耗量可降低约33%，电消耗量可降低约24%，低压蒸汽消耗量可降低约12%。该系统整体技术满足硫磺回收装置规模大型化以及环保排放的要求，值得推广应用。
