It usually contains a light source, photocatalytic material, reaction chamber and temperature control system. This reactor can promote chemical reactions under light conditions and ensure the stability and repeatability of reaction conditions through temperature control. Photocatalytic reaction: using photocatalysts to generate redox reactions under light conditions to degrade organic pollutants or eliminate pathogens. Temperature control: through the built-in temperature control system, the reaction temperature is accurately controlled to ensure that the reaction is carried out at the optimal temperature, improving reaction efficiency and product quality. Multiple reactions: suitable for gas phase, liquid phase, gas-liquid phase and other reaction systems, such as photocatalytic degradation, hydrogen production, oxygen production, CO2 reduction, etc. Importance Improve reaction efficiency: accurate temperature control and efficient photocatalytic materials can significantly improve reaction efficiency and reduce reaction time. Ensure reaction stability: temperature control ensures stable reaction conditions, reducing side reactions and catalyst deactivation caused by temperature fluctuations. Environmentally friendly: photocatalytic reactions usually use solar energy or simulated sunlight, which is a green and environmentally friendly chemical reaction method widely used in environmental purification and new energy development. Parts needed and their functions Light source: provides light energy to excite photocatalysts. Common light sources include xenon lamps, mercury lamps, LED lamps, etc. Photocatalytic material: such as TiO2, CdS, etc., absorbs light energy and promotes chemical reactions. Reaction chamber: usually made of high borosilicate glass or quartz material, with good light transmission and chemical stability. Temperature control system: including temperature-controlled water jacket, temperature sensor and controller, to ensure accurate control of reaction temperature. Air pipe: goes deep into the bottom of the reactor for gas inlet and outlet. Glass tap: controls the on-off of the gas. Online sampling inlet: facilitates sampling and sampling during the reaction. Flange seal: ensures the air tightness of the reactor to prevent gas leakage. Possible problems and solutions during use Reactor internal fouling: problem: long-term use will cause internal fouling of the reactor, affecting heat and mass transfer performance. Solution: clean the inside of the reactor regularly, which can be done with acid or alkali solution. Reactor leakage: problem: reactor leakage will cause gas or liquid leakage, affecting normal work. Solution: check the sealing parts and connections of the reactor, and repair or replace them in time. Light source failure: problem: the light source is not bright or the light intensity is not enough, affecting the normal work of the reactor. Solution: check if the power cord is connected well and make sure the power switch is on. If the light source is still not bright, it may be that the bulb or tube is broken and needs to be replaced. For the problem of insufficient light intensity, you can use a lux meter to measure the light intensity, and if necessary, adjust the position of the light source or replace a higher power light source. Catalyst failure: problem: catalyst failure will affect the normal work of the reactor. Solution: replace the catalyst regularly or reactivate the catalyst. Inaccurate temperature control: problem: the temperature inside the reactor is too high or too low, affecting the reaction efficiency and product quality. Solution: check if the temperature control system is working properly, including heating and cooling devices.Ensure that the temperature sensor is correctly placed and functioning properly. If the temperature control is unstable, the temperature sensor may need to be calibrated or the circuit and software of the temperature control system checked. Gas flow control is inaccurate: Problem: Gas flow is unstable or cannot be adjusted, affecting the stability of the reaction conditions. Solution: Check if the gas source is sufficient, and if there is a leak in the gas pipeline. Check if the gas flow meter and control valve are working properly. If the flow meter shows inaccurate, it may need to be calibrated or replaced. Stirring problem: The stirring speed is unstable or cannot be started, affecting the uniformity of the reaction. Solution: Check if the stirring motor and drive system are working properly. Make sure the stirring paddle is installed correctly and there is no obstacle. If the stirring speed is unstable, check if the stirring controller settings are correct, or if the stirring motor needs to be replaced. Through the above measures, the problems that may occur during the use of the photocatalytic reactor can be effectively solved, ensuring the normal operation and efficient work of the equipment.
