Embodiment 1

[0035] Such as image 3 As shown, a method for using a radial flow pressure swing adsorption bed adopts a radial flow pressure swing adsorption bed, which is characterized in that it comprises the following steps:

[0036] The pretreated dry air is used as the raw material gas, and its main component (volume percentage) is . N 2 79%, O 2 was 21%. The adsorption pressure is required to be 3 atmospheres, which is measured by the pressure sensor outside the outlet pipe of the gas port II2 of the adsorption bed I23 and the adsorption bed II24, and more than 90% oxygen enrichment is prepared through the pressure swing adsorption process.

[0037] Step 1, through the adsorption pressure of 3 atmospheres, the rated flow rate of the blower 34 is 0.118kg / s and the requirements of the oxygen concentration of the product above 90%, the adsorption bed is cylindrical, based on this, stainless steel is selected as the material and passed through Icem in Ansys Calculated and produced wit...

Abstract

A radial flow pressure swing adsorption bed and its use method, belonging to the technical field of chemical machinery, including a cover, the large-diameter end of the cover is connected with one end of the shell to form a cavity, and the small-diameter end of the cover is fixedly installed with the connecting pipe I, The other end of the shell is axially interspersed with air port II, and the air port II is located at the end of the outer part of the shell and is fixedly installed with the connecting pipe II. A stepped air distribution plate is arranged in the cavity, and one end of the stepped air distribution plate is fixedly installed with the shell, and the stepped air distribution plate The other end of the plate is fixedly installed with the inlet guide baffle, and the axial guide sleeve located outside the stepped air distribution plate is fixedly installed on the inlet guide baffle, and the inlet guide baffle passes through the guide baffle positioning groove and the support column Fixed installation with cover. The inner and outer stepped air distribution plates are used to distribute the injected raw gas evenly; the flow form of the adsorption bed airflow is Ω-shaped, and the internal concentration field tends to be cylindrical by filling different diameters of adsorbents in stages, making the product gas concentration High and stable.

Description

technical field [0001] The invention belongs to the technical field of chemical machinery and relates to pressure swing adsorption (PSA) and gas mass transfer application technology. The invention can be applied to various large and medium-sized pressure swing adsorption devices using pressure swing adsorption technology. Background technique [0002] The pressure swing adsorption process is widely used in the field of gas separation. For example, industrial production of oxygen enrichment, desulfurization, and CO removal 2 Wait. Due to the advantages of simple process flow, convenient operation, normal temperature operation, low equipment maintenance rate and low energy consumption, the pressure swing adsorption method can be fully automated and the oxygen production concentration is about 90%, the highest is 95.5%, etc., this method is widely used in Industrial gas separation field. [0003] As the most important equipment of the pressure swing adsorption process, the ...
