Problems solved by technology

Carbon dioxide has CO, H in the manufacturing process 2 O, hydrocarbons, O2 and other harmful impurities, carbon dioxide producers will also purify the above media in the production process, but due to the limitation of large chemical production and process, process flow, it is necessary to produce ultra-high purity carbon dioxide with impurity content less than 1PPm very difficult

Abstract

The invention relates to a carbon dioxide purification device. The device comprises a first adsorption tower (1), a catalytic tower (2) and a second adsorption tower (16); the first adsorption tower (1) is filled with silica gel; the second adsorption tower (3) is filled with activated carbon; magnesium perchlorate is carried on the activated carbon; the first adsorption tower (1) is provided witha gas inlet pipe (13) and an inert gas pipe (5); the inert gas pipe (5) is communicated with a gas inlet end of the first adsorption tower (1) sequentially through a stainless steel electromagnetic valve (14) and a stable-flow valve (11); a gas outlet end of the first adsorption tower (1) is connected with the catalytic tower (2); a gas outlet pipeline of the catalytic tower (2) is connected withthe second adsorption tower (16) sequentially through a corrugated pipe (7) and a metal filter (9); and a pure gas pipeline (6) is arranged on the second adsorption tower (16). According to the scheme, the original impurities in the carbon dioxide are purified through a catalyst catalytic conversion and adsorption combined technology, and the content of the impurities in the CO2 gas is less than1PPm, so that the high-purity CO2 is obtained.

Description

technical field [0001] The invention relates to the field of carbon dioxide purification, in particular to a carbon dioxide purification device. Background technique [0002] Carbon dioxide (English name: Carbon dioxide) is a common compound in the air, and its molecular formula is CO 2 , consisting of two oxygen atoms and one carbon atom connected by a covalent bond. There is a trace amount of carbon dioxide in the air, accounting for about 0.03% of the total volume of the air. Carbon dioxide dissolves in water to form carbonic acid, a weak acid. Because the air contains carbon dioxide, the pH value of rainwater is usually greater than or equal to 5.6, CO 2 itself is not toxic, but when CO in the air 2 When the normal content is exceeded, it will have harmful effects on the human body. High-purity carbon dioxide is used in artificial diamonds, carbon dioxide lasers, optical fiber production, etching in the electronics industry, gas for analysis equipment, non-polar non...
