Abstract

The invention discloses a vertical radial flow adsorber. The adsorber includes an inlet pipe, a tank body, a spherical head, an outer cylindrical screen, a middle cylindrical screen, an inner cylindrical screen, a central channel distributor, a first adsorption bed, and a second adsorption bed. , exhaust pipe, discharge port, two filling / discharging ports, manhole, load-bearing channel steel, the central flow channel distributor is located in the cavity of the inner cylindrical screen, and consists of a hollow cylinder of equal diameter , porous hollow cylinder, and solid circular table, this structural design can reduce the adverse effect of the height of the adsorption bed on the uniform distribution of the flow field, and significantly increase the maximum design height of the vertical radial flow adsorber. The design of the adsorber of the present invention has the advantages of small occupied area, low energy consumption, high flow field uniformity and the like under the condition of the same processing capacity.

Description

technical field [0001] The invention relates to the field of gas separation and purification, in particular to a vertical radial flow adsorber. Background technique [0002] At present, industrial gases are mainly obtained by air separation. Before the separation, the processing air should be pretreated with a purifier to prevent impurities such as water vapor, carbon dioxide, acetylene and other hydrocarbons from being precipitated, causing blockage or even explosion accidents. In recent years, iron and steel, metallurgy, chemical industry, aerospace and many other fields have developed rapidly, and the demand for industrial gases such as nitrogen and oxygen has increased sharply. Correspondingly, air purification equipment has been developing in the direction of large-scale and low energy consumption. Compared with other air purification equipment such as traditional vertical axial flow adsorbers and horizontal vertical flow adsorbers, vertical radial flow adsorbers have...
