络合铁法脱硫在天然气行业应用广泛,将反应生成的硫磺富集回收是反应器稳定运行的关键之一。在反应器底部引入锥段对硫磺的富集、沉降和回收很有帮助,为了避免硫磺在锥段侧壁长期沉积和结块,应分层通入扰动气体。通入气量不能太小,以至达不到避免锥段侧壁硫磺沉积的作用,也不能太大,使得硫磺难于沉降。本研究采用欧拉多相流模型,对锥段硫磺沉降进行了模拟,研究了硫磺浓度和通气速度对硫磺沉降的影响。结果表明:硫磺浓度对沉降速度影响较小,而通气速度对沉降影响明显。随着气速增大,硫浆沉降越来越慢,对所研究的体系,最大通气速度应小于0.75m/s。Chelated iron desulfurization is widely used in natural gas industry, the enrichment and removal of sulfur particles is a key factor for stable operation of the reactor. The design of a cone section at the bottom of the reactor is helpful for the enrichment, settlement and recovery of sulfur particles. In order to avoid long-term deposition and agglomeration of sulfur particles at the sidewall of the cone section, disturbed gas should be injected at different heights. The flow rate of the disturbed air should not be too small, so as to avoid sulfur deposition at the side wall of the cone section. It should also not be too large, so as to prevent the settlement of the sulfur particles too difficult. Eulerian multiphase model was used to simulate sulfur deposition in the cone section. The effects of sulfur concentration and air flow velocity on sulfur deposition were studied. The results showed that sulfur concentration had little influence on the settling velocity, while the effect of air flow velocity on the settlement was obvious. The deposition rate of sulfur particle decreased with the increasing of gas velocity, the maximum air flow velocity of the system should be less than 0.75m/s to ensure the settlement of the sulfur particles. Complex iron method desulfurization widely used in the natural gas industry, the reaction of sulfur enrichment recovery is one of the key to the stable operation of the reactor. The introduction of the conical section at the bottom of the reactor is very helpful for enrichment, sedimentation and recovery of sulfur. In order to avoid the long-term deposition and agglomeration of sulfur on the sidewall of the conical section, the disturbance gas should be stratified. Inflow of gas can not be too small to reach the cone wall to avoid the role of sulfur deposition, nor too much, making it difficult to settle sulfur. In this study, Eulerian phase flow model was used to simulate the sulfur deposition in the conical section. The effects of sulfur concentration and aeration velocity on sulfur deposition were studied. The results show that the sulfur concentration has little effect on the sedimentation velocity, while the aeration velocity has obvious influence on the sedimentation. With the increase of gas velocity, the sedimentation of sulfur slurry is getting slower and slower. For the system studied, the maximum aeration velocity should be less than 0.75m / s.
