Embodiment Construction

[0018] Such as figure 1 and figure 2 The moving bed gas-solid radial reactor shown includes a shell, which is composed of a cylindrical side wall 11 , an upper seal 10 and a bottom seal 12 . The shell is provided with an inner net 14 and an outer net 13 which are arranged sequentially from the inside to the outside along the axial direction of the shell. An annular space 16 is formed between the inner net 14 and the outer net 13. After the annular space 16 is filled with catalyst, a cylindrical catalyst is formed. bed. A reactant inlet 1 is provided on the top cover 10 of the housing, and a reaction product outlet 3 is provided on the bottom cover 12 . A plurality of (more than one) catalyst introduction pipes 2 are arranged at intervals on the upper head 10 at the top of the reactor for introducing the catalyst into the annular space 16 . A plurality of (more than one) catalyst discharge pipes 4 with a circular cross-section are arranged at intervals on the bottom head 12...

Abstract

The present invention discloses a gas-solid radial reactor of moving bed for chemical industry and petroleum processing industry, and is characterized by that the lower portion of inner not of said reactor is equipped with a skirt, and the external surface of said skirt is inclined from top to bottom along the direction from inner net toward outer net, its upper edge is connected with inner net, and its lower edge is connected with internal surface of closure head of the bottom, and the radial position of the lower edge is positioned in internal side of radial position of catalyst outlet pipe, and the external surface of said skirt is generally made into circular truncated cone side face or frustum side face. Said invention can effectively reduce or eliminate flow dead zone of catalyst inthe reactor, at the same time the structure of said skirt is simple, and easy to implement. It is specially applicable to hydrocarbon conversion reaction and catforming reaction.

Description

(1) Technical field [0001] The invention relates to a moving bed gas-solid radial reactor, in particular to a moving bed gas-solid radial reactor used for catalytic reforming reactions in petroleum refining. (2) Background technology [0002] In moving bed gas-solid radial reactors, gas-phase reactants react in the presence of solid catalyst particles. The catalyst moves axially along the reactor, and the gas phase reactants pass through the catalyst bed along the radial direction or nearly radial direction of the reactor. A 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 (shell) of the reactor, and in the reactor there is a cylindrical outer net ( Or a group of fan-shaped barrels with small holes arranged axially along the outer wall of the reactor (gas distributor) and a circular space formed by a cylindrical inner net. After the catalyst is loaded, a cylindrical catalyst...
