摘要:
元素硫在集输管道中沉积会引起堵塞和腐蚀问题，球阀处是集输管道中较易出现大量硫沉积的部位之一。为此，采用数值模拟的方法研究高含硫天然气中析出的硫颗粒在球阀处的运移沉降规律，选用雷诺应力模型模拟球阀处的流场，选用Lagrange颗粒轨道模型追踪硫颗粒在球阀处的运动轨迹，探讨影响硫颗粒在球阀处沉积的因素。结果表明：气流进入球阀内将会出现压力损失和流动分离，气流进口速度和球阀开度会对流场产生影响；硫颗粒在球阀处的沉积率随气流流速和颗粒直径的增大而增大，随球阀开度的增大而减小；重力和离心力是造成硫颗粒在球阀处出现大量沉积的重要原因。
Abstract:
The deposition of elemental sulfur in gathering pipeline will cause the problems of clogging and corrosion, and sulfur deposition is more prone to occur in the ball valve in gathering pipeline. Therefore, the method of numerical simulation was used to study the laws of movement and settlement for sulfur particles precipitated from natural gas with high contents of sulfur in ball valve. The Reynolds stress model was used to simulate the flow field in the ball valve, and the Lagrange particle trajectory model was used to track the movement trajectory of sulfur particles in the ball valve, then the factors affecting the deposition of sulfur particles in the ball valve were studied. The results showed that the gas flowed into the ball valve would occur pressure loss and flow separation. The gas inlet velocity and valve opening would affect the flow field. The deposition rate of sulfur particles in ball valve would increase with the increase of gas velocity and particle diameter, and decrease with the increase of valve opening. The important reasons resulting in the deposition of massive sulfur particles in the ball valve were the gravity and centrifugal force.
