Problems solved by technology

The device can provide a better fluid distribution effect, but the internal structure is complex, which increases the pressure drop when the fluid passes through the device
Moreover, the increase in the number of chambers leads to an increase in the number of pipes, reducing 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
[0007] In summary, the current fluid distribution equipment still has the following problems that need to be improved: (1) The flow path of the fluid in the equipment is long, and it is easy to form a flow dead zone
(2) The fluid has a relatively large concentration gradient in the equipment, and the fluid mixing is not sufficient
(3) The internal structure causes a large pressure drop when the fluid flows through the equipment

Embodiment 1

[0063] Example 1 illustrates the dispensing effect of the fluid mixing and distributing device of the present invention.

[0064] Experimental method: the fluid mixing and distributing equipment provided by the present invention has a structure such as Figure 7A As shown, the ratio of the cross-sectional area of ​​the container where the fluid mixing and distributing equipment is located to the total cross-sectional area of ​​the channel (9) is 47.5:1, and the side and bottom of the storage tank of the fluid collecting and mixing chamber are provided with small holes, The ratio of the total opening area to the cross-sectional area of ​​the equipment is 1:60. The ratio of the total opening area of ​​the cavity of the fluid inlet or extraction component to the total cross-sectional area of ​​the channel (9) is 1:42. A fluid mixing distribution device was placed in the experimental system described above. Then, slowly pour water into and fill the container without disturbing t...

Embodiment 2

[0078] Example 2 illustrates the mixing effect of the fluid mixing and dispensing device provided by the present invention.

[0079] The fluid distribution equipment provided by Fang Ming, with the same structure as in Example 1, was placed in the experimental system described above. Then, slowly pour water into and fill the container without disturbing the particle bed. After the system is filled with water, increase the flow of water so that the water in the bed flows downward at an average linear velocity of 20mm / s. Then, a tracer, usually a certain concentration of brine, is injected from the fluid inlet and outlet pipes, and a series of concentration measurement points are set in a plane at a certain height between the bottom of the device and the downstream particle bed to evaluate the mixing effect of the device. The judging standard is the relative average deviation of the brine concentration measured at the in-plane concentration measurement point from the in-plane c...

Abstract

The invention relates to fluid mixed distribution equipment. The fluid mixed distribution equipment comprises an upper surface supporting component (5), a fluid collecting board (7), at least one channel (9), a fluid collection mixing chamber (8) and a lower surface fluid distribution component (6), wherein the upper surface supporting component is used for supporting an upper solid particle bed and permitting a fluid to pass through the upper solid particle bed; the fluid collecting board extends horizontally to penetrate through the cross section area of a container and is isolated from the upper surface supporting component (5); the at least one channel penetrates through the fluid collecting board (7); the fluid collection mixing chamber is positioned under the fluid collecting board, is communicated with the channel (9), and is connected with the fluid collecting board (7), the fluid collection mixing chamber comprises a storage tank positioned under the channel (9) and an upright board which is arranged inside the storage tank and vertical to the fluid collecting board, and the storage tank is provided with holes or slot seams; and the lower surface fluid distribution component is positioned below the fluid collection mixing chamber (8) and is isolated from the fluid collection mixing chamber (8). The fluid mixed distribution equipment provided by the invention can effectively collect fluid, also strengthens the mixing of the fluid, and improves the distribution of the fluid to a certain extent.

Description

technical field [0001] The present invention relates to a device for mixing and / or distributing fluids. More specifically, it relates to a container containing multiple solid particle beds, collecting the fluid flowing down from the upstream particle bed, fully mixing the collected fluid with the fluid introduced from the outside, and evenly distributing the mixed fluid to equipment in the particle bed downstream of the equipment. 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...
