Abstract

The invention discloses an oxygen production adsorption tower. The tower comprises a tower body, an annular adsorption bin and a gas outlet channel. A gas inlet channel is arranged at the bottom of the tower body, and a filler channel is arranged at the top of the tower body. The annular adsorption bin is arranged in the tower body, the top of the annular adsorption bin is connected with the top of the tower body, and the annular adsorption bin is communicated with the filler channel; and the outer peripheral wall of the annular adsorption bin and the side peripheral wall of the tower body are arranged at intervals so as to form a gas inlet cavity between the outer peripheral wall of the annular adsorption bin and the side peripheral wall of the tower body, the gas inlet cavity is communicated with the gas inlet channel, and a gas outlet cavity is formed in the inner peripheral wall of the annular adsorption bin. According to the oxygen production adsorption tower, dead space can be reduced, gas distribution is uniform, and the operation efficiency of a system is improved.

Description

technical field [0001] The present invention relates to the field of gas separation and purification, in particular to an oxygen production adsorption tower. Background technique [0002] In related technologies, in order to obtain oxygen enrichment with low energy consumption and low cost, a pressure swing adsorption oxygen production device is generally used to produce oxygen. With the needs of a large number of smelting projects, the demand for the scale of pressure swing adsorption oxygen production equipment is also increasing, which in turn promotes the development of pressure swing adsorption oxygen production equipment in the direction of large-scale, and the adsorption tower is a pressure swing adsorption oxygen production equipment key equipment. [0003] In related technologies, there are two types of oxygen-generating adsorption towers in the industry: axial flow adsorption towers and radial flow adsorption towers. Oxygen plants with a domestic oxygen productio...
