The invention provides a pipeline embedded type gas-liquid separation structure for a fuel tank and the fuel tank; the structure comprises impeller units, the impeller unit is provided with a verticalpartition plate with the upper arc-shaped end face and the lower arc-shaped end face attached to the inner wall of a pipeline, a transverse partition plate is arranged on one side of the vertical partition plate, and the vertical partition plate intersects with the transverse partition plate; the left and right arc-shaped end faces of the transverse partition plate are attached to the inner wallof the pipeline; two spiral partition plates extend from one side of the vertical partition plate and are located in diagonal areas formed by intersection of the vertical partition plate and the transverse partition plate respectively. The arc-shaped edge of the spiral partition plate is attached to the inner wall of the pipeline. The multiple impeller units are combined in a linear mode to form apipeline embedded type gas-liquid separation structure. According to the technical scheme, gas and liquid can be effectively separated, liquid fuel is prevented from entering the carbon canister, thestructure is small, and the internal volume of the fuel tank is not occupied when used in cooperation with the exhaust pipeline.
本发明提供一种燃料箱用管道内嵌式气液分离结构及燃料箱,包括叶轮单元,所述叶轮单元布置有上下弧形端面与管道内壁贴合的竖隔板,所述竖隔板一侧布置有横隔板,所述竖隔板与所述横隔板相交;所述横隔板左右弧形端面与管道内壁贴合;所述竖隔板一侧延伸有两块螺旋状隔板,所述螺旋状隔板分别位于所述竖隔板和所述横隔板相交形成的对角区域;所述螺旋状隔板弧状边缘与管道内壁贴合;多个叶轮单元一字型结合形成管道内嵌式气液分离结构。该技术方案可有效分离气体和液体,避免液态燃料进入炭罐,结构小巧,与排气管道配合使用,不占用燃料箱内部容积。
