Abstract

The invention relates to the technology field of solid particle catalyst continuous reaction and regeneration and discloses a particle catalyst conveying pipeline connector which comprises a connector component 4A and a connector component 4B. The connector component 4A and the connector component 4B are of male-female structures. The inner diameter of a middle pipe of the connector component 4A of the male structure is matched with the inner diameter of a catalyst conveying pipe. The outer diameter of the 4A middle pipe is larger than that of the catalyst conveying pipe. A pipe section at one end of the connector component 4B of the female structure is fixedly connected in a smooth mode with the solid particle catalyst conveying pipe, the inner diameter of a pipe section at the other end is matched with the inner diameter of the catalyst conveying pipe, the outer diameter of the pipe section is larger than that of the catalyst conveying pipe, and the pipe section is provided with a sealing ring groove connected with the connector component 4A of the male structure. The connector is used for pipeline connecting, the structure is simple, manufacturing and mounting are convenient, and inner smoothness and continuity in a long-distance catalyst conveying pipeline connecting head are achieved.

Description

technical field [0001] The invention belongs to the technical field of continuous reaction and catalyst regeneration by means of solid particle catalysts in petroleum and chemical processing processes, and in particular relates to a pipeline connector for transporting particle catalysts. Background technique [0002] In many petroleum and chemical processing processes, such as continuous catalytic reaction-regeneration devices such as reforming, aromatization, and dehydrogenation, solid particle catalysts are transported from the bottom of one reaction or regeneration device to another reaction or regeneration device. top. The solid particle catalyst is conveyed by compressed gas through a pipeline at the bottom of the reaction or regeneration equipment. Solid particle catalysts are generally spherical or cylindrical, and solid particle catalysts are very expensive. Due to the special structure of the reaction and regeneration equipment, the granular catalyst must ...
