Concentric circle gas separation device

Abstract

The invention relates to a concentric circular gas separation device. The concentric circular gas separation device comprises a barrel body, and an inlet side end cover and an outlet side end cover which are arranged at the two ends of the barrel body respectively, wherein the inlet side end cover is provided with a plurality of gas inlets; the outlet side end cover is provided with a plurality of gas outlets; the barrel body comprises an inner-layer barrel body, a middle-layer barrel body and an outer-layer barrel body which are coaxially arranged; the two ends of the inner-layer barrel body, the middle-layer barrel body and the outer-layer barrel body are in sealed connection with the inlet side end cover and the outlet side end cover respectively; the inlet side end cover is provided with a gas distribution structure for distributing gas flow entering from the gas inlets; and a filtering structure is arranged between one end of the barrel body and the inlet side end cover, and a vibration feeding structure is arranged between the other end of the barrel body and the outlet side end cover. The concentric circular gas separation device can be used for buffering the gas flow and can avoid non-uniform distribution of the gas flow, and the structure is not easy to bend or deform.

Description

technical field [0001] The invention relates to the field of gas separation and purification, in particular to a concentric gas separation device. Background technique [0002] In modern industry, the technology of adsorption and separation of gas by gas separator is widely used in petrochemical, pharmaceutical, metallurgy, electronics and other industries, such as gas separation, drying and air purification, wastewater treatment, oxygen and nitrogen production, etc. Adsorption materials in the gas separator generally use filter materials such as molecular sieves and activated carbon. Molecular sieves or activated carbon can adsorb one or several components in the mixed gas raw material. When the gas passes through the gas separator, one or several components The components are adsorbed, while the other components flow out and are separated to achieve the separation effect.

AI Technical Summary

Problems solved by technology

[0003] In the gas separator in the prior art, the shell is usually a single-layer cylindrical shape. When the adsorber is working, the airflow enters from the inlet of the adsorber and flows out from the outlet of the adsorber through molecular sieve or activated carbon. When the airflow enters the adsorber, it will impact on the shell, and the existing shell cannot buffer the gas, and the shell structure is prone to buckling deformation; in addition, the airflow is directly blown into the adsorber, and there is a problem of uneven airflow distribution, which makes the adsorption of the gas separator less efficient
