A photothermal catalytic degradation device for toxic gases

Abstract

This invention discloses a photothermal catalytic degradation device for toxic gases. The device includes a light source, a quartz tube, quartz wool, a catalyst bed structure, and insulation cotton. Quartz tubes are connected to both ends of the catalyst bed structure. Quartz wool is placed at the end of the quartz tube connected to the catalyst bed structure. Insulation cotton is placed outside the catalyst bed structure. A light source is positioned above the catalyst bed structure. The catalyst bed structure is filled with catalyst. In this invention, the catalyst only needs to be pressed into tablets and sieved before being filled into the reactor for photothermal catalytic testing, eliminating the need for complicated procedures such as ultrasonically suspending the catalyst with ethanol, dripping it through a glass fiber filter membrane, and drying it. The main structure of this invention is a fused, integrally formed quartz tube, providing excellent sealing and preventing leakage that could pollute the environment and cause health hazards to experimental personnel, while also affecting experimental results (reducing the reaction gas flow rate) and potentially leading to an overestimation of the catalyst's catalytic performance.
