Problems solved by technology

However, the distribution of bubbles in this sparger is too dispersed, resulting in low gas holdup inside the entire column, which is only suitable for reactions that do not require high gas holdup, and has certain limitations.

Embodiment 1

[0054] This embodiment provides a gas distributor (for a schematic diagram of its structure, refer to Figure 1a and Figure 1b ), the gas distributor includes an annular gas distribution pipe 11, a gas distribution box 12 located in the ring of the annular gas distribution pipe 11, and an inlet connected to the gas distribution pipe 11 and the gas distribution box 12 respectively. Trachea 13;

[0055] The air intake pipe 13 is respectively connected to the gas distribution pipe 11 and the gas distribution box 12 through the three air intake branches 131, so as to realize the fixing and air intake of the gas distribution pipe 11 and the gas distribution box 12;

[0056] Among the three air intake branches 131, one air intake branch 131 is connected to the gas distribution box 12, and the remaining two air intake branches 131 are connected to the radially opposite sides of the annular gas distribution pipe in pairs; the air intake pipe 13 Parallel to the plane where the annula...

Embodiment 2

[0060] Except for the following content, other content is identical with embodiment 1:

[0061] The air intake pipe 13 is respectively connected to the gas distribution pipe 11 and the gas distribution box 12 through the five air intake branches 131, so as to realize the fixing and air intake of the gas distribution pipe 11 and the gas distribution box 12;

[0062] Among the five air intake branches 131, one air intake branch 131 is connected to the gas distribution box 12, and the remaining four air intake branches 131 are connected to the radially opposite sides of the annular gas distribution pipe in pairs, and these four The connection ports between the two air intake branches 131 and the gas distribution pipe 11 are uniformly distributed on the gas distribution pipe; Air intake pipe 13 is vertical.

Embodiment 3

[0064] Except for the following content, other content is identical with embodiment 1:

[0065] On the gas distribution pipe 11, the air hole 14 close to the connection port of the gas distribution pipe 11 and the intake branch 131 has a small aperture, and is far away from the gas hole 14 at the connection port of the gas distribution pipe 11 and the intake branch 131. The aperture is large;

[0066] Preferably, on the gas distribution box 12, the air hole 14 close to the connection port of the gas distribution box 12 and the intake branch 131 has a small aperture, and is far away from the connection port of the gas distribution box 12 and the intake branch 131 The air holes 14 have a large aperture.

Abstract

The invention relates to a gas distributor and a system comprising the gas distributor. The gas distributor comprises an annular gas distribution pipe, an intra-annular gas distribution box positionedin the annular gas distribution pipe, and a gas inlet pipe respectively connected with the gas distribution pipe and the gas distribution box, wherein the gas inlet pipe is connected with the gas distribution pipe and the gas distribution box through at least two branched gas inlet branches, so that the fixation and the gas inlet of the gas distribution pipe and the gas distribution box are realized; gas holes are formed in the surfaces of the gas distribution pipe and the gas distribution box. The structure of the gas distributor is simple; the operation is stable; the uniform distribution performance is good.

Description

technical field [0001] The present invention relates to a gas distributor and a system including the gas distributor, in particular to a gas distributor, a bubble column including the gas distributor and a system. Background technique [0002] The production process in the chemical industry often involves reactions involving gas or liquid, which requires stirring components that can mix gas-liquid two-phase or gas-liquid-solid three-phase. The gas distributor is a widely used component, especially in the equipment of multiphase fluidization reaction. [0003] At present, there are mainly two types of gas distributors used in industry: plate gas distributors and tubular gas distributors. One of its main functions is to make the reactants evenly distributed, speed up the reaction efficiency and shorten the reaction period, how to better control The pressure drop and flow rate to achieve better gas distribution are still the focus of research. [0004] CN 105944630 A disclose...
