Carbon dioxide capture device

Abstract

The present invention provides a device for fixing and recovering carbon dioxide by passing it through a chemical agent in a compressed air circuit. [Solution] The device consists of a body, a bowl attached to the body, a hollow section, and a carbon dioxide recovery section, wherein the carbon dioxide recovery section is equipped with a basic oxide agent, the body has an inlet and an outlet for compressed air, the hollow section divides the inside of the bowl into two regions, the inside of the hollow section and the outside of the hollow section, the upper part of the hollow section is connected to the inlet or the outlet, the sides of the hollow section are permeable to the agent but do not allow it to pass through, and the carbon dioxide recovery section is located inside or outside the hollow section, and has a means for compressed air entering from the inlet to pass through the carbon dioxide recovery section and be discharged from the outlet.

Claims

1. A carbon dioxide capture device installed in a compressed air circuit, It consists of a body, a bowl attached to the body, a hollow section, and a carbon dioxide recovery section. The carbon dioxide recovery unit is equipped with a basic oxide agent, The body has an inlet and an outlet for compressed air, The hollow portion divides the inside of the bowl into two regions: the inner region of the hollow portion and the outer region of the hollow portion. The upper part of the hollow section is connected to the inlet or outlet, The sides of the hollow section are impermeable to the chemical and breathable. The carbon dioxide recovery unit is positioned inside or outside the hollow section. A carbon dioxide recovery device characterized in that compressed air entering from the inlet passes through the carbon dioxide recovery section and is discharged from the outlet.

2. The carbon dioxide recovery apparatus according to claim 1, characterized in that the aforementioned agent consists of calcium hydroxide.

3. The carbon dioxide recovery apparatus according to claim 1, characterized in that the aforementioned agent is in pellet form.

4. The carbon dioxide recovery device according to claim 3, characterized in that the air permeability of the side surface of the hollow portion is higher at the bottom.

5. The carbon dioxide recovery device according to claim 3, characterized in that the lower part of the bowl has an opening and closing section, through which the chemical in the bowl can be recovered.

6. The carbon dioxide recovery device according to claim 1, characterized in that a check valve is provided on the upstream side of the inlet.

7. The carbon dioxide recovery apparatus according to claim 1, characterized in that the piping to the carbon dioxide recovery apparatus is branched, with one branch entering the inlet of the body and the other branch flowing in from the bottom of the bowl.

8. The carbon dioxide recovery device according to any one of claims 1 to 7, characterized in that the carbon dioxide recovery device is located downstream of the air dryer.
