Utility Model Patent - Gas-Solid Phase Photocatalytic Reactor
Patent Number: ZL 2023 2 0652037.7
BoFeiLe Technology has introduced another utility model patent — Gas-Solid Phase Photocatalytic Reactor. This unique innovative device is a significant breakthrough for BoFeiLe Technology in the field of photocatalysis, aiming to address the issue of insufficient contact between the catalyst and reaction gas, leading to low reaction efficiency in existing reactors.
In recent years, photocatalysis technology has been increasingly applied in clean energy, air pollution control, CO₂ reduction, and other fields. However, existing gas-solid phase photocatalytic reactors often adopt passive gas diffusion, resulting in insufficient contact between the catalyst and reaction gas, leading to low reaction efficiency. To address this issue, BoFeiLe Technology has developed this new type of gas-solid phase photocatalytic reactor.
This reactor includes the reactor body, catalyst support, inlet pipe, outlet pipe, and control pipe.
The reactor body has a reaction chamber, and the catalyst support is located inside the reaction chamber to hold the catalyst. The control pipe is connected to the reaction chamber to transport the reaction gas into the reaction chamber. The inlet pipe connects the inlet of the reaction chamber and the outlet of the fluid pump, while the outlet pipe connects the outlet of the reaction chamber and the inlet of the fluid pump, forming a loop so that the reaction gas can circulate in the loop, making more effective contact with the catalyst and thereby improving reaction efficiency.
The advantages of this design include:
The reaction gas can circulate in the loop, significantly increasing the chances of contact with the catalyst.
Precise delivery of the reaction gas to the reaction chamber is ensured through the control pipe, ensuring accuracy and stability.
This patent is applied to the "PLR OTPR-I Online Temperature Measurement Gas-Solid Phase Photocatalytic Reactor," which is compatible with the Labsolar-6A system. It uses a low heat dissipation design, is compatible with powder, porous membrane, and thin-layer block materials. It utilizes intense light to heat the material, enabling real-time online temperature measurement of the catalyst surface and sampling and inspection of gas components during the reaction.
The PLR OTPR-I Online Temperature Measurement Gas-Solid Phase Photocatalytic Reactor mainly includes PLR OTPR-1 type and PLR OTPR-2 type:
• PLR OTPR-1 type is suitable for use with the Labsolar-6A all-glass automatic online trace gas analysis system;
Labsolar-6A System Equipped with Online Gas-Solid Phase Photocatalytic Reactor Live Scene
• PLR OTPR-2 type is suitable for the gas-solid phase experiments of photocatalysis and photothermal catalysis in a flowing system.
Unlike the passive diffusion form, the PLR OTPR Gas-Solid Phase Photocatalytic Reactor adopts a gas "penetration" form, effectively ensuring sufficient contact between the reaction gas and photocatalyst, improving mass transfer efficiency. The PLR OTPR Gas-Solid Phase Photocatalytic Reactor is equipped with a dedicated in-situ infrared temperature measurement port for non-contact real-time measurement of the surface temperature of the photocatalyst, recorded with a constant temperature jacket to minimize heat dissipation.
