This invention discloses a plasma ventilation and purification device and method, relating to the field of energy conservation and environmental protection. When airflow occurs, the plasma ventilation and purification device uses a wind pressure sensor to collect wind pressure data and sends it to a centralized control module. The centralized control module outputs stored voltage, current, and frequency operating parameters to power the plasma generator. The generated plasma density is indirectly detected by an ultraviolet sensor and an ozone sensor. After the detection data is sent to the centralized control module, it automatically adjusts the output voltage, current, and frequency values ​​to ensure that the plasma density is consistently highest and the ozone content is lowest under different environments. The cathode plate can collect particles and can be extracted for cleaning, eliminating the need for intermediate and high-precision filters, ultraviolet generators, and other facilities, thus reducing the size and weight of the device. The ozone degrader converts ozone into oxygen, ensuring that the ozone content does not exceed the standard and improving air purification efficiency. This achieves energy-saving and environmentally friendly effects such as no consumables required, human-machine coexistence, sterilization, pollution degradation, and automatic operation.
