A filter element self-flushing fine filter comprises a fine filter shell, an effluent tube arranged on the upper part of the fine filter shell and a filter element arranged in the fine filter shell. The filter element uses a nano-fiber membrane filter core, and a plurality of liquid inlet tubes inclined downward along the circumferential direction are arranged on the fine filter shell. The axis of the liquid inlet tube is tangent to the outer wall of the filter core, and the liquid inlet tube is in the fine filter shell. The deflection direction on the circumferential wall is the same. The lower part of the fine filter shell is a storage chamber, and the bottom part of the fine filter shell is provided with a slag discharge port. The advantages are: simple structure, ingenious design, the axis of the inlet pipe is tangent to the outer wall of the filter element, while the liquid enters the filter element, the solid particles attached to the outer wall of the filter element can be cleaned, the outlet direction of the inlet pipe is inclined downward, and the cleaning area of the filter element can be increased, thus realizing the self-flushing function of the filter element, reducing the frequency of the removal and cleaning of the filter element, and prolonging the fine filter. The utility model has the advantages of long service life, high filtration efficiency, and is suitable for the application of petrochemical filtration.

滤芯自冲洗精滤器
本技术属于石化器械领域,特别涉及一种滤芯自冲洗精滤器。
技术介绍
精滤器是石油化工生产过程常用的设备,用于固液分离或者除杂。CN200991607Y公开了一种精滤器,该精滤器适宜炼油过程中焦化污水脱焦粉、氨压机入口脱机械杂质和液体,脱除杂质效果好。但液体从进液口进入到精滤器内,经滤芯过滤,固体颗粒聚积在滤芯外表面,粘附在滤芯上,影响过滤的效果,需要经常将滤芯拆卸清洗,缩短精滤器的使用寿命,并且影响生产效率。
技术实现思路
本技术要解决的技术问题是提供一种滤芯自冲洗精滤器,结构简单,无需拆卸滤芯,就可以对滤芯外壁附着的固体颗粒进行清洗,降低滤芯拆卸清洗频率,延长精滤器的使用寿命。本技术是这样实现的:一种滤芯自冲洗精滤器,包括精滤器壳体、设在精滤器壳体上部的出液管和设置在精滤器壳体内的滤芯,其特殊之处在于:在精滤器壳体上沿圆周方向均布设有多个内端口向下倾斜的进液管,所述进液管的轴线与滤芯外壁相切,且所述进液管在精滤器壳体圆周壁上的偏转方向一致,所述精滤器壳体下部为贮存室,在精滤器壳体底部设有排渣口。进一步的,所述进液管分为二组呈上下布置。进一步的,所述进 ...
