摘要
为了评价目前天然气净化用滤芯气液分离性能,利用聚结型滤芯气液过滤性能的检测装置研究了滤芯的放置方式、滤芯的有效厚度及填充密度等相关因素对气液过滤性能的影响。结果表明:在相同条件下,滤芯垂直于地面放置比水平位置放置时排液较顺畅,气液过滤效果较好,并且压降至少降低25%;不同材质滤芯,随着滤芯厚度在6～32mm范围内增加,滤芯稳态压降增加,过滤器出口液含量减小,过滤性能提高;滤芯的填充密度增加,滤芯压降增大,过滤器出口液含量减小。
In order to evaluate the gas-liquid filtration performance of filtration elements widely used in natural gas transmission pipelines,the influences of several factors,including the filtering mode,packing thickness and packing density of fibrous filter elements,were measured by experiments.The experimental results showed that filtration performance of filter placed vertically was better than that of filter placed horizontally,and the pressure drop of the former was less by 40% under the same condition.As the thickness of fibrous filter material increased from 6 mm to 32 mm,the pressure drop increased,the liquid content at filter outlet decreased,and the filtration efficiency was increased.Higher packing density of fibrous filter material led to higher filtration efficiency and pressure drop.
