Carbon dioxide adsorbent, carbon dioxide adsorption device and manufacturing method thereof

Abstract

The invention discloses a carbon dioxide adsorbent, a carbon dioxide adsorption device and a manufacturing method of the carbon dioxide adsorption device. The carbon dioxide adsorbent is prepared from 20-60 parts by weight of titanium oxide, 30-70 parts by weight of aluminium oxide and 10-50 parts by weight of magnesium oxide, adsorbs carbon dioxide in laughing gas efficiently and purifies the laughing gas. The manufacturing method of the carbon dioxide adsorption device comprises the following steps: 1) adding deionized water to a hydrothermal kettle; 2) adding titanium salt, aluminium salt and magnesium salt to the hydrothermal kettle; 3) preparing a salt solution from a modifier and adding the salt solution to the hydrothermal kettle; 4) placing a blank filling layer into the hydrothermal kettle and performing hydrothermal treatment; 5) taking out the filling layer to obtain an adsorbent filling layer; 6) installing the adsorbent filling layer on a filtering channel of the carbon dioxide adsorption device. With adoption of the manufacturing method, nanoscale carbon dioxide adsorbent is uniformly attached to the filling layer, so that the adsorbent filling layer has efficient carbon dioxide adsorption performance.

Description

technical field [0001] The invention relates to a carbon dioxide adsorbent, a carbon dioxide adsorption device and a manufacturing method thereof, and belongs to the technical field of gas filtration and purification. Background technique [0002] In China's laughing gas application market, the largest customer group is the LCD panel industry, which needs 5N high-purity laughing gas. At present, mainstream LCD panel factories are researching higher-level display technologies, and the two major technologies of LTPS and Oxide have begun mass production in foreign mainstream factories. At present, China is still in the stage of research and development or trial production. These two technologies, Both require the use of high-purity laughing gas in large quantities, but the original LCD panel technology hardly uses it, so it promotes the explosion of laughing gas applications. [0003] Applications in other Asia-Pacific regions are mainly in South Korea, Taiwan and Japan. Sout...
