Greenhouse gas treatment apparatus

A greenhouse gas treatment apparatus comprising:

• a primary cooling chamber filled with low-temperature air by means of a first cold air supply pipe;
• a secondary cooling chamber, formed to have a space independent of the primary cooling chamber and filled with the low-temperature air through a second cold air supply pipe, the secondary cooling chamber being maintained at a temperature lower than that of the primary cooling chamber;
• a condensation pipe through which air containing greenhouse gases is suctioned by an air-intake port and sequentially passes through the primary cooling chamber and then the secondary cooling chamber to undergo heat exchange and be discharged, wherein water vapor contained in the air condenses in the condensation pipe within the primary cooling chamber and is collected in a first liquid tank, and carbon dioxide in the air condenses in the condensation pipe within the secondary cooling chamber and is collected in a second liquid tank, and non-condensed gas is discharged through a pressure control valve at an outlet portion of the secondary cooling chamber;
• a first compressor provided at an inlet region of the secondary cooling chamber along the condensation pipe;
• the pressure control valve provided at the outlet portion of the secondary cooling chamber along the condensation pipe;
• a second compressor disposed between the first compressor and the pressure control valve along the condensation pipe to enable independent pressure control upstream and downstream of the second compressor;
• and
• a heat-exchanger configured to transfer heat from the secondary cooling chamber to the primary cooling chamber so that the secondary cooling chamber is maintained at a temperature lower than the primary cooling chamber,
• wherein:
• the primary cooling chamber and the secondary cooling chamber are respectively provided with a first exhaust valve and a second exhaust valve, and the first cold air supply pipe and the second cold air supply pipe are respectively provided with a first inlet valve and a second inlet valve, so that the temperature and pressure of the primary cooling chamber and the secondary cooling chamber are independently adjusted by opening and closing operations of each valve,
• wherein:
• the first cold air supply pipe is branched into a first branch pipe through which the low-temperature air is supplied to an inner space of the primary cooling chamber, and a second branch through which the low-temperature air is supplied directly to the condensation pipe.
