| Abstract: | In order to analyze the sulfur deposition problem of the cage sleeve throttle value at the wellhead of sour natural gas field,a numerical simulation model of sulfur deposition was established based on the Reynolds stress model,the component transport model and the discrete phase model,and the laws and influencing factors of sulfur deposition in the cage sleeve throttle value were analyzed.The results showed that the sulfur deposition mainly appeared at the lower edge of the outer side of orifice facing the incoming flow,the edge of sleeve and the inner side of valve core,and the deposition at the lower edge of the outer side of orifice was the most serious.For this position,with the increase of airflow inlet velocity,the sulfur deposition rate increased first and then decreased,which reached the maximum value when the airflow velocity was 5 m/s.At the same time,the maximum deposition rate at the lower edge of the outer side of orifice was negatively related to the valve opening,orifice diameter and inner diameter of valve core,while it was positively related to the particle size.As the orifice diameter and the inner diameter of valve core increased,the maximum deposition rate approximately decreased at an average rate of 7.8×10-5 kg/(m2·mm) and 7.4×10-5 kg/(m2·mm). |
