Fluid Mixing Distributors, Equipment and Vessels for Solid Particle Beds

Abstract

The present invention relates to a kind of fluid mixing distributor, equipment and container for solid particle bed, this fluid mixing distributor (8) comprises fluid distributing pipe (10), fluid receiving pipe (9), and fluid distributing pipe ( 10) A connected fluid communication pipe (22), the fluid receiving pipe (9) extends upward from the fluid distribution pipe (10) in the axial direction and communicates with the fluid distribution pipe (10), the fluid receiving pipe (9) A fluid mixing cap (16) is fastened on it, and an annular gap (91) for fluid passage is formed between the fluid mixing cap (16) and the fluid receiving pipe (9), and each fluid distribution pipe (10) A fluid distribution port (24) is formed on it. The fluid mixing distributor and equipment provided by the invention can improve the fluid flow uniformity in the container provided with the solid particle bed, make the fluid fully mixed, and reduce the pressure drop when the fluid flows through.

Description

technical field [0001] The invention relates to a fluid mixing distributor, equipment and container for solid particle bed. Background technique [0002] In the field of petrochemical industry, the process of contacting fluid with solid particles in a container containing solid particles is widely used in operations such as adsorption separation and catalytic reaction. Among them, adsorption separation is a commonly used separation technology in petrochemical industry, and it has a very good effect on the purification of mixtures with similar structures and small differences in boiling points. The equipment used for adsorption separation includes fixed bed, moving bed and simulated moving bed, among which simulated moving bed is the main equipment used in adsorption separation at present. In the simulated moving bed, the stationary phase adsorbent can be assumed to move against the moving direction of the material, the mixed material to be separated is continuously input at...

AI Technical Summary

Problems solved by technology

This device can provide a relatively good fluid distribution effect, but the internal structure is complicated, and the increase in the number of chambers leads to an increase in the number of pipes, which reduces the effective volume in the container

The equipment has a relatively simple shape and structure, and is suitable for large-scale containers. For smaller containers, it is difficult to install the equipment

[0008] In summary, the current fluid mixing and distribution equipment still has the following problems that need to be improved: (1) The flow path of the fluid in the large equipment is long, and it is easy to form a flow dead zone

(2) The fluid has a relatively large concentration gradient in the large equipment, and the fluid mixing is insufficient

(3) The complex internal structure leads to a large pressure drop when the fluid flows through the equipment
