Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the residence time of the gaseous reactant in the catalyst bed layer caused by the use of the existing fan-shaped cylinder has a large difference, and the distribution of the gaseous reactant or gas product (referred to as gas) on the fan-shaped plate is uneven. Uniformity and the problem that the fan-shaped cylinder is easily squeezed and deformed by the catalyst during the start-up, shutdown and operation of the device

Embodiment Construction

[0023] Refer to FIG. 1 for a fan-shaped cylinder (referred to as a fan-shaped cylinder) for a gas-solid radial reactor of the present invention, and refer to FIGS. 2 to 8 . The fan-shaped cylinder shown in Figure 1 includes a lifter 12, a top connector 8, a top plate 1, a blind cylinder 2, a back plate 10, a fan-shaped plate 4, a bottom ring plate 6 and a bottom plate 7; the back plate 10 and the fan-shaped plate 4 are circular arcs In terms of surface shape, the bending direction of the back plate 10 is the same as that of the reactor cylinder (see FIG. 13 and FIG. 14 ), and the central axes of the two are coaxial. The top plate 1 is welded on the top of the blind cylinder 2, and the air lifter 12 and the top connector 8 are arranged on the top plate 1, see Fig. 1 and Fig. 2 . Also can not be provided with air-lifting cylinder 12, and offer air-lifting port (figure omitted) on top plate 1. The back plate 10, the blind cylinder 2 and the bottom ring plate 6 are all solid plat...

Abstract

A sectorial barrel for the radial gas-solid reactor features that the curving direction of the sectorial plate with arc surface is same as the curving direction of the barrel body of reactor, the side plates are arranged at both sides of sectorial plate and at both sides of back plate between bottom of blind barrel and the top of ring plate, said sectorial plate may be the strip net composed of metal strips and ribbed plate or the perforated plate, the central axis is coaxial with the central axis of said barrel body, and the catalyst and powder discharging outlets are made on the bottom plate of sectorial barrel. Its advantages are uniform distribution of gas on the sectorial plate.

Description

technical field [0001] The invention relates to a fan-shaped cylinder for gas-solid radial reactors in petroleum refining and petrochemical industries, in particular to a fan-shaped cylinder for catalytic reforming fixed-bed or moving-bed gas-solid radial reactors. Background technique [0002] Existing fixed bed or moving bed gas-solid radial reactor (such as the gas-solid radial reactor used in the catalytic reforming process) is provided with a cylindrical central tube with the central axis of the reactor cylinder as the central axis, Fan-shaped cylinders are uniformly arranged along the inner wall of the reactor cylinder. The annular space between the central cylinder and the fan-shaped cylinder is filled with catalyst to form a catalyst bed; the fan-shaped cylinder is used as a flow channel for gas reactants or a flow channel for gas products. When the fan-shaped cylinder is damaged, only a few damaged fan-shaped cylinders need to be replaced, which is convenient for i...
