NITROGEN SUPPLYING APPARATUS CAPABLE OF IMPROVING YIELD AND PROFITABILITY BY EFFECTIVELY REGENERATING AN OXYGEN ADSORBENT MATERIAL IN AN ADSORPTION COLUMN

摘要

PURPOSE: A nitrogen supplying apparatus is provided to rapidly stabilize pressure swing adsorption(PSA) performance and to reduce the amount of an absorbent material by increasing the desorption rate of a PSA type nitrogen generator.;CONSTITUTION: A nitrogen supplying apparatus includes at least one pair of adsorption columns(114, 115), an oxygen discharging pipe, a dual plate checking valve, and a low noise unit(200). The adsorption columns are filled with an oxygen absorbent material. In case of the decompression of the adsorption columns, detached oxygen from the adsorbent material is discharged through the oxygen discharging pipe. The dual plate checking valve is installed on the oxygen discharging pipe. The low noise unit is installed at the end of the oxygen discharging pipe and reduces noise generated from the discharge of oxygen.;COPYRIGHT KIPO 2012
