CO2 capture system for greenhouse using membrane technology

摘要

The present invention relates to a carbon dioxide capture system for a greenhouse using a membrane technology. The carbon dioxide capture system includes: a main compressor for compressing a gas mixture existing inside and outside the greenhouse; a dryer for separating gas from the compressed gas mixture in the main compressor and cooling the gas; a membrane filter for separating a specific gas from gas from which moisture has been removed through the dryer; a flow meter for controlling the pressure of the carbon dioxide to a predetermined pressure when the carbon dioxide is separated through the membrane filter; and a receiving tank capable of compressing and storing the carbon dioxide to deliver the carbon dioxide of the predetermined pressure to the right place at the right time. The carbon dioxide capture system for a greenhouse using a membrane technology separates CO2 from exhaust gas expelled into the atmosphere, a farmhouse, or a heating green house, and captures and stores the CO2, and then supplies the CO2 to a plant factory for aquaculture and to a greenhouse. Therefore, the carbon dioxide capture system produces an ideal concentration of CO2 needed for crop growth, improves crop productivity, and reduces harmful gases expelled into the atmosphere, thereby reducing environmental pollution.
