摘要
PURPOSE: An apparatus for evaluating performance of a photo catalyst for removing volatile organic compounds by photolysis is provided to evaluate the performance of the photo catalyst by measuring decomposition efficiency of volatile organic compounds using a continuous flow method. CONSTITUTION: An apparatus for evaluating performance of a photo catalyst includes an electric control section, a reaction gas introducing section, a reaction section and a measuring section. The electric control section controls power and fluid supplied to the apparatus. The reaction gas introducing section includes a fluid feeding section(60), electronic valves(15,25,35), MFCs(16,26,36), a gas mixing reservoir(70) and a temperature/humidity adjusting chamber(40). The fluid feeding section(60) stores and feeds nitrogen gas(10), reaction gas(11), and purified air(12). The reaction section includes a UV ray generating part and a reactor. Mixed reaction gas is introduced into the reactor, reacted with UV ray and photo catalyst and introduced into the measuring section. A PID(Photo Ionization Detector) and gas chromatographic flame photometric detector are used to detect and analyze density of mixed reaction gas in order to evaluate decomposition efficiency.
