Integrated Air Purification Process Demo System

The system connects two drying towers, two catalytic hydrogen-removal towers, and two deep adsorption towers—a total of six towers in series—to sequentially perform moisture removal, hydrogen removal, and deep purification of compressed air. An online dew-point analyzer at the outlet keeps the dew point steadily below -65 °C, while multi-point temperature, pressure, flow rate, and H₂ concentration measurements continuously calculate the operating status and purification efficiency of each tower. All pneumatic valves across the process are centrally scheduled by the control system, supporting one-click manual/automatic switching and online regeneration/activation, making it an ideal platform for air purification process instruction, demonstration, and validation.
