A vortex separation based CCS platform relief valve impurity grading device

Abstract

This utility model relates to an impurity grading device, and more particularly to an impurity grading device for a CCS platform pressure relief valve based on eddy current separation. The device includes a valve body, arc-shaped blocks, and a cleaning mesh frame. The valve body is a cylindrical structure with openings at both ends and a central through-hole. The openings of the valve body are the inlet and outlet ends, respectively. Arc-shaped blocks are evenly spaced on the inner wall of the inlet end of the valve body. A cleaning mesh frame is detachably connected to each arc-shaped block, and the cleaning mesh frame has two openings, one large and one small, facing the inlet end of the valve body. Through the synergistic action of a conical eddy current stabilizer and a spiral guide vane, the fluid is forced to form a high-speed rotating eddy current. Centrifugal force is used to throw large particles of impurities (such as sand and metal shavings) towards the inner wall of the cleaning mesh frame. Small particles undergo secondary filtration as they pass through the mesh openings of the cleaning mesh frame with the fluid, thereby achieving graded filtration of impurities.
