Positive and negative oxygen ion air purification system using dielectric barrier discharge for rail transport

A positive and negative oxygen ion air purification system using dielectric barrier discharge for rail transport, the system comprising:

• an air intake device including a first damper and a second damper, wherein the first damper is in communication with the second damper;
• an evaporator disposed within the air intake device, wherein gas flowing through the first damper and the second damper passes through the evaporator;
• a purification device, wherein the gas flowing through the first damper and the second damper passes through the purification device, and wherein the purification device includes a mounting plate, a power supply module and an ion generation module, wherein the purification device is disposed on the air intake device by the mounting plate, and the power supply module includes an input end, a transformer, and an output end;
• a detection device;
• and
• a control device connected to the detection device and which is connected to the air intake device and the purification device,
• wherein the ion generation module includes a high-voltage emission electrode plate, a filling medium and a grounding electrode plate arranged sequentially attached to one another, and
• wherein the power supply module provides high-voltage alternating current to the ion generation module.
