Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the object of the present invention is to provide an activated carbon buffered photocatalytic reactor with simple structure, convenient operation, strong adaptability, high photocatalytic efficiency, and long-term stable operation. In order to solve the problem of fluctuations in the concentration of exhaust gas, the unstable exhaust gas will be sorted into a balanced and stable airflow through reasonable air distribution and pre-treatment activated carbon filters, thereby improving the efficiency of photocatalytic reactions; honeycomb activated carbon-loaded catalysts provide active vacancies for photocatalytic reactions, and at the same time prolong the time spent in the exhaust gas. The residence time of organic matter improves the efficiency of catalytic reaction; the terminal activated carbon filter prolongs the degradation time of active particles on organic matter, which can effectively use active particles and further improve the purification efficiency
