Abstract
The invention discloses a fixed bed reactor in a grid support particle orderly packing structure. A fixed bed reactor body is provided with an inlet cowling, a housing and an outlet cowling, wherein achannel with a rectangular cross section is arranged in the housing; a grid support particle orderly packing is arranged in the channel; and particles are solid catalyst or reactant particles. The grid support particle orderly packing is a near body centered cubic packing and a near face centered cubic packing. The particles are fixed by a grid support; the grid support is a plate grid structurein which circular or square through holes are regularly distributed; and the grid support is used for quickly obtaining the required particle orderly packing and a grid channel. With the adoption of the fixed bed reactor in the grid support particle orderly packing structure, a reaction under a high-pressure condition can be effectively finished; fluid pumping work in the channel is decreased; andparticle abrasion is reduced.
Description
technical field [0001] The invention relates to the technical field of reactors, and relates to a fixed-bed reactor and an ordered packing structure of particles. It is used to quickly and accurately build a fixed bed with an ordered packing structure of particles, so as to realize efficient heat exchange, energy storage, dust removal or chemical reaction. Background technique [0002] Fixed bed reactor is a common reactor in petrochemical, energy storage and dust removal and purification fields, such as ammonia synthesis tower, sulfur dioxide contact oxidizer, solar collector and gas purifier, etc. [0003] Spherical particle packed beds are often used in fixed bed reactors, which have the advantages of compact structure, large internal specific surface area, strong flow disturbance, simple design and manufacture, and stable operation. They are mainly used to realize gas (liquid) solid phase reactions and Gas purification, etc. The particle packed bed can be divided into ...
