Porous filtering material for filtering outwards-thrown oil slurry

Abstract

The invention belongs to the technical field of filtering materials, and particularly relates to a porous filtering material for filtering outwards-thrown oil slurry. A single filter element has a two-section structure, so that the acting stress applied to a single filter element body can be dispersed, the structural strength of the filter element is improved, and the probability of breakage and deformation of the filter element is reduced. The single filter element can be assembled, and a plurality of filter elements can be connected by using the reinforcing ribs, so that the overall structural strength of the grouped filter elements is effectively improved, and the problem of fracture phenomenon when the grouped filter elements are applied to actual working conditions is solved. The porous filtering material is simple in design, low in cost and wide in application range. According to the invention, the filtering precision and the circulation amount of the filter element are effectively improved; and the porous filter material provided by the invention avoids the problem that fine catalyst particles block pores of the filter element. The porous filtering material disclosed by the invention has a good online blowback effect while ensuring relatively high filtering precision, the service life of the filter element is prolonged, and the running cost of the filter element is reduced.

Description

technical field [0001] The invention belongs to the technical field of filter materials, and in particular relates to a porous filter material used for filtering externally thrown oil slurry. Background technique [0002] Catalytic oil slurry is a by-product of the catalytic cracking process in the oil refining industry. It contains a large amount of saturated hydrocarbons and polycyclic aromatic hydrocarbons. After further processing, it can be used as a blended fuel oil component, and can also be used as a raw material for needle coke and carbon fiber. However, because it also contains a large number of catalyst particles and impurities such as colloids and asphaltenes attached to the catalyst, it causes many difficulties in the deep processing of the catalytic oil slurry. In order to solve the problem of purification and separation of oil slurry in catalytic cracking units, researchers have designed and developed related separation technologies, mainly including electrost...
