AI Technical Summary
The ozone generated during the processing of nuclear pore membranes in the ultraviolet photosensitization chamber is emitted directly without treatment, causing air pollution and posing a threat to the health of workers.
An ultraviolet photosensitization chamber was designed, comprising a processing chamber, an air pump, a MnO2-based honeycomb catalyst, and a sealing structure. It decomposes ozone into harmless oxygen through catalytic decomposition and is equipped with a sealing strip and an adjustable position of the ultraviolet lamp. It is automatically controlled in conjunction with temperature and ozone sensors.
It effectively prevents the direct emission of ozone without treatment, avoids air pollution and damage to human health, improves the safety and efficiency of the device, and simplifies the catalyst replacement process.
