Renewable large flow filter core

Abstract

The invention discloses a renewable large flow filter core. The renewable large flow filter core comprises a filter core and is characterized in that one end of the filter core is provided with an upper end cover, the other end of the filter core is provided with a bottom cover, the filter core comprises an inner skeleton, an outer skeleton and a filter material between the inner skeleton and the outer skeleton, the filter material is folded to form a corrugated or zigzag structure, and the circumferential surface of the outer skeleton is covered with a plurality of rows of filter holes, and in each row of the filter holes, each two adjacent filter holes are staggered. Through improvement of the raw filter core in the structure and performance and use of a novel corrugated structure, a filtering area is greatly improved to 20 times that of the ordinary filter core. Through change of fluid inlet and outlet directions from an outward direction to an inward direction, a filter core loading capacity is improved, formation of filter cake is promoted and filter core filtering efficiency is 99.5% or more. Through use of the inner and outer skeletons, the filter core can bear pressure from both directions and backwashing regeneration of a large flow filter core is realized.

Description

technical field [0001] The invention belongs to the technical field of separation, and in particular relates to a regenerable large-flow filter element, which is used for the separation and collection of liquid-solid and gas-solid in fluid. Background technique [0002] With the rapid development and application of advanced technology, the requirements for fluids in life or industrial production are getting higher and higher, especially for water and gas. [0003] First of all, compressed air is the most important power source in modern industry because of its flexibility and reliability. However, the oil, water and dust particles in the compressed air will damage the air equipment to varying degrees, resulting in high maintenance costs. [0004] Secondly, a large number of solid particles contained in water have a greater impact on the process. [0005] Furthermore, the solid particle content of other various fluids also has higher requirements. [0006] All of these req...
