Particulate matter bed layer support structure and high flux axial reactor

Abstract

The invention relates to the field of petrochemical engineering equipment, and particularly provides a particulate matter bed layer support structure and a high flux axial reactor. The particulate matter bed layer support structure comprises a support grid and a compression grid arranged in the vertical direction, wherein the support grid is positioned under the compression grid; the support gridand the compression grid have the matched concave-convex structure, so that an axial space and a transverse space are formed between the support grid and the compression grid and are used for installing a particulate matter bed layer. Compared with a plane grid support structure with the same diameter, the particulate matter bed layer support structure has the advantages that the circulation areaof the particulate matter bed layer can be increased; the flux of the reaction medium circulation is improved, so that the processing capability of the reactor can be improved; when the processing quantity is identical, the equipment diameter can be reduced; the cost is reduced; the anti-bending cross section modulus of the support structure can be obviously improved. The high-flux reactor provided by the invention can improve the utilization rate of the particulate matter catalyst.

Description

technical field [0001] The invention relates to the field of petrochemical equipment, in particular to a particle bed support structure and a high-throughput axial reactor using the particle bed support structure. Background technique [0002] For the catalyst bed support structure of the reactor, it is generally divided into two types, namely, a planar support grid and a cylindrical support grid. These two support structures correspond to axial flow reactors and radial flow reactors, respectively. Among them, the axial fixed bed reactor has a long history and a wide range of applications. These two reactors include the following characteristics: [0003] Axial fixed bed reactors generally use a planar grid support structure, such as figure 1 shown. The catalyst bed of this type of reactor is arranged in a horizontal cake shape, the fluid flows through the bed from top to bottom along the axial direction, and the bed has no heat exchange with the outside world. The struc...

Problems solved by technology

But this kind of reactor also has some disadvantages: the bed of the catalyst bed is generally thick, and the resistance of the reactants to flow through the bed is large. In order to reduce the resistance, a large particle catalyst must be used; There are high requirements to prevent the catalyst particles from being pulverized by the impact of high-speed airflow

However, the structure of the radial reactor is more complicated than that of the axial reactor in terms of process design and equipment manufacturing, which limits its popularization and application.
