Carbon nannotube adsorption component as well as preparation method and application of carbon nannotube adsorption component

The invention discloses a carbon nannotube adsorption component as well as a preparation method and application of the carbon nannotube adsorption component. Carbon nanotubes of the carbon nannotube adsorption component grow at one side of each metal wire mesh belt, a strip-shaped structure is formed at the side by arranging the sides, not provided with carbon, of the metal wire mesh belts at intervals; upper and lower outer layers of the strip-shaped structure are packaged by using filter cloth, and the whole strip-shaped structure is strip-shaped and can be wound; when being wound to form acylindrical structure, the strip-shaped structure has the height-to-diameter ratio of 1:1 to 1:5; and a carbon nannotube adsorption device applying the carbon nannotube adsorption component is internally filled with the carbon nannotube adsorption component, the void ratio of a bed layer of the component is 70-95%, and no gas or liquid distribution devices are arranged in the device. The inventionfurther discloses a prepa
