Moving bed gas-solid radial reactor

Abstract

The invention relates to a moving bed gas-solid radial reactor, and belongs to the field of catalysis devices. The moving bed gas-solid radial reactor comprises a shell and a catalyst chamber, and the catalyst chamber is defined by an inner ring plate, an outer ring plate, a bottom arc plate and a top sealing plate; the upper ends of the inner ring plate and the outer ring plate are correspondingly hung at the top of the shell through an inner ring hanging plate and an outer ring hanging plate, so that a certain distance is formed between the bottom arc plate at the bottom end of the catalyst chamber and the inner surface of the bottom of the shell; a gas bottom sealing plate is connected to the lower port of the inner ring plate serving as a gas collecting pipe and is connected with a gas inlet pipe penetrating through the bottom of the shell; and the inner ring plate and the outer ring plate are each of a composite structure formed by stacking grating plates on a Johnson net, and the Johnson net is located on the catalyst side. The reactor is uniform in flow field, low in pressure drop, and capable of ensuring that the side wall of the catalyst chamber is not unstable under the conditions of large diameter and high bed layer, the service lives of the inner ring plate and the outer ring plate are longer in a corrosive gas environment, and the catalyst is not easy to block meshes, so that the flowing smoothness of reaction gas is ensured.

Description

technical field [0001] The invention belongs to the field of catalytic devices, in particular to a moving bed gas-solid radial reactor. Background technique [0002] In a moving bed gas-solid radial reactor, the gas phase reactants react in the presence of solid catalyst particles, wherein the catalyst moves along the reactor axis, and the gas phase reactants pass through the catalyst bed radially or nearly radially of the reactor . [0003] The traditional moving bed gas-solid radial reactor generally consists of an upper head, a cylindrical side wall and a bottom head to form the outer wall (i.e. the shell) of the reactor, and in the shell there is a cylindrical outer net and The annular space formed by the cylindrical inner net, after the catalyst is filled in the space, a cylindrical catalyst bed is formed, and the inner surface of the bottom head is the bottom of the catalyst bed. The cylindrical inner net can prevent catalyst particles from entering the inner space o...
