Abstract

The invention relates to a thermal swing type carbon dioxide recovery and concentration device which is a honeycomb rotor recovery and concentration device for recovering carbon dioxide gas from duct gas and the like, that can recover carbon dioxide gas at as high a recovery rate as possible and concentrate to as high a concentration as possible, that can be made smaller, that can use low-temperature heat waste of 100 DEG C or less and reduce the amount of energy for recovery and concentration, and that has high durability. [Solution] A honeycomb rotor carrying adsorption material (solid amines, and the like) particles having adsorption capacity for carbon dioxide gas is rotated in a casing divided and sealed into at least an adsorption zone and a desorption zone and is brought into contact with raw material that includes carbon dioxide in a state where the honeycomb in the adsorption zone is moist so as to adsorb the carbon dioxide gas while carrying out evaporative cooling of water, and then the honeycomb that has adsorbed the carbon dioxide gas is moved to the desorption zone and brought into contact with low pressure vapor so as to desorb high concentration carbon dioxide gas. Thus, it is possible to continuously recover carbon dioxide gas at a high recovery rate and high concentration.

Description

technical field

[0001] The invention relates to a temperature swing adsorption carbon dioxide recovery and concentration device, which recovers with a high recovery rate, can be concentrated to a high concentration, can be miniaturized, has high durability, can utilize waste heat below 100° C., and consumes less energy. Background technique

[0002] As a response to global warming, the world is trying to reduce carbon dioxide emissions from industry, cars and homes as much as possible. For this reason, efforts are being made to improve energy-consuming equipment into energy-saving equipment and to replace old equipment. In addition, as equipment for generating energy such as power generation, use equipment using renewable energy such as sunlight or wind power, or improve the power generation efficiency of thermal power plants, and develop the recovery of carbon dioxide discharged from thermal power plants in the future. Concentrated to store in the ground or deep sea techno...
