摘　　要：采用以玻璃弹簧为载体的新颖负载型光催化剂 ,设计实验测试该催化剂的辐射能分布状况 ,通过实验测量修正双通量模型的参数 ,并使用修正双通量模型进行计算 ,上述实验值与理论计算值吻合较好 ,说明修正双通量模型可准确模拟多相光催化反应器的辐射能传递行为 .最后 。A novel reactor design for the use of titanium dioxide-coated glass-springs is developed for photocatalytic purification and treatment of water and air. The manufacture of the coating of the glass-springs is discussed. An experimental device was designed for testing the radiation intensity distribution of gas-solid photocatalytic reactor. The model parameters of the extended two-flux model were measured, then radiation intensity distribution inside the reactor was computed. The experimental results agreed with the model-computed results. Moreover, the radiation intensity distribution and the total radiative energy absorption rate were described by the above-mentioned model in gas-solid parallel-plate reactor packed with the photocatalyst supported on glass-springs.
