Integrated device for removing carbon dioxide gas in gas

Abstract

The invention discloses an integrated device for removing a CO2 gas in a gas. The integrated device comprises a device body, an air inlet pipe, a sprayer, a demister, a flow guide plate, an alcohol amine rich liquor accumulating chamber, a hollow fiber membrane module, an alcohol amine barren liquor accumulating chamber, and a circulating pipe. An air inlet hole is installed in the device body. The device body is internally provided with the air inlet pipe. An upper part of the air inlet pipe is the three-level sprayer. The demister and the flow guide plate are successively installed above thesprayer. The alcohol amine rich liquor accumulating chamber is positioned below the air inlet pipe. The hollow fiber membrane module is installed at a lower part of the alcohol amine rich liquor accumulating chamber. The alcohol amine barren liquor accumulating chamber is installed below the hollow fiber membrane module. Regenerated alcohol amine solution can be guided into the sprayer for circulating by the circulating pipe, or guided into the alcohol amine rich liquor accumulating chamber for performing secondary treatment. The device is simple, low in investment cost, and capable of continuously removing the CO2 gas in the gas so as to obtain a purified gas, and synchronously performing alcohol amine solution regenerating operation. A technological process is simplified, the cost is saved, and the operation is convenient.

Description

technical field [0001] The invention relates to the field of gas purification, in particular to an integrated device for removing carbon dioxide gas in gas. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain temperature, humidity and acid-base conditions. Usually, various organic matter such as human and animal manure, straw, kitchen waste, and domestic sewage can be placed in a closed biogas digester for fermentation, that is, it will be decomposed and transformed by a variety of biogas digester fermentation microorganisms to produce biogas. As a renewable clean energy with high calorific value, biogas has attracted great attention. my country has abundant reserves of biogas resources and a huge market demand. Domestic biogas is currently mainly used as fuel for rural stoves, and its use value is low. The development of biogas at home and abroad shows that biogas power ge...

Problems solved by technology

[0003] Biogas is a fuel with relatively low methane content, and biogas contains a large amount of carbon dioxide (CO 2 ) and other impurities, in order to improve the efficiency of biogas combustion and reduce pollution, it is necessary to purify the biogas before using the biogas to remove the impurity components in the biogas. Alcohol amine method is often used in industry. This process involves absorption Towers, coolers, flash tanks, filters, booster pumps, buffer tanks, heat exchangers, regeneration towers, reboilers, reflux tanks and other equipment and devices are complicated to operate, require large investment, and occupy a large area
