AI Technical Summary
In existing technologies, activated carbon filters have limited adsorption capacity and are prone to secondary pollution, while catalytic filters have poor activity and high air resistance at room temperature, resulting in low purification efficiency.
The purification device, composed of heating elements and heat sinks, features a catalyst layer with high activity at high temperatures. The heating elements heat the catalyst layer, allowing it to maintain its activity in a high-temperature environment for an extended period, thus improving purification efficiency. Furthermore, by optimizing the area and air resistance ratio of the purification device, the probability of contact between the catalyst and formaldehyde molecules is increased.
While reducing wind resistance, it significantly improves purification efficiency. The catalyst layer maintains long-term activity at high temperatures, effectively removing formaldehyde with a purification efficiency of over 80%.
