NITROGEN GAS SUPPLY SYSTEM CAPABLE OF CONTROLLING NITROGEN FLOW RATE AND CONCENTRATION AND METHOD OF SUPPLYING NITROGEN GAS USING THE SAME

摘要

The nitrogen flow and concentration control are possible nitrogen supply system and supply of nitrogen using the same method are disclosed. A nitrogen feed system, the nitrogen flow rate and concentration adjustment in accordance with an embodiment of the present invention is an air compressor for compressing the inlet air by the blower motor; Compressed air is supplied from the air compressor and the gas separation membrane module to separate discharge the oxygen and nitrogen contained in the compressed air; Detecting a concentration of oxygen contained in the nitrogen is separated from the discharge gas separation membrane module, the oxygen concentration detected to set the concentrations of oxygen and nitrogen contained in the setting unit is separated from the discharge gas separation membrane module; In association with the concentration of oxygen is set by the oxygen concentration detector and the setting unit to adjust the flow rate and the concentration of nitrogen is separated discharge in the gas separation membrane module, and controls the blower motor flow to control the flow rate of compressed air supplied to the gas separation membrane module control unit; And is connected to the air compressor, it includes a dehumidifying unit for removing moisture contained in the compressed air compressed in an air compressor to supply compressed air to remove moisture in the gas separation membrane module.
