Abstract

The present invention discloses a large-flow vertical radial flow adsorption device with the characteristic of layered parallel connection design, and a method thereof. The adsorption device comprises a housing, an adsorbent filling layer, an upper unit inner side multi-pore distribution cylinder, an upper unit outer side multi-pore distribution cylinder, an inner side diversion cylinder, a lower unit inner side multi-pore distribution cylinder, a lower unit outer side multi-pore distribution cylinder, an outer side diversion cylinder, a middle baffle, a middle baffle filler cover, a bottom support plate, and a flow finishing shelf. According to the present invention, the internal of the adsorption device is designed into the two separate adsorption unit connected in parallel and comprising the upper adsorption unit and the lower adsorption unit, such that the adverse influence of the height of the adsorption bed on the uniform flow field distribution can be eliminated, and the maximum design height of the vertical radial flow adsorption device can be significantly increased; and the large-flow vertical radial flow adsorption device with the characteristic of layered parallel connection design has advantages of shell housing diameter, small occupation area, high flow field uniformity and the like in the case of the same air treatment amount.

Description

technical field [0001] The invention relates to the field of gas purification and separation, in particular to a large-flow vertical radial-flow adsorber designed in layered parallel connection in large-scale air separation equipment and a method thereof. Background technique [0002] In the industrial process, it is often necessary to purify and separate the gas. For example, in the air separation system, molecular sieve adsorbers are often used to remove impurities with high freezing points such as water, carbon dioxide, and alkanes contained in the high-pressure gas from the air compressor, so as to avoid subsequent Safety problems such as ice blockage and explosion occurred in the process. With the rapid development of the world economy, the demand for industrial gases such as oxygen and nitrogen has increased sharply in many industrial fields such as iron and steel, metallurgy, and chemical industry. Correspondingly, air purification and separation equipment has been d...
