摘要
设计了一种新型的浅槽型填充床光催化反应器,实验以亚甲基蓝作为模拟污染物,采用不锈钢曝气网,实现了高效的无动力曝气,在浅槽中交错安置挡板显著地改善了反应器中的流动状态。实验表明,以玻璃弹簧为载体的光催化剂可以较好的提高传质效果。反应器能充分利用太阳光中直射和散射的紫外光,在阴天也能有效地运行。
A novel shallow-gutter photocatalytic reactor packed with loaded photocatalyst has been designed. Methyl-ene blue was used as simulated pollutant to evaluate the efficiency of the reactor. The experimental result showed that the stainless steel aeration web realized high effective with no dynamic aeration, and a stagger baffle arranged in the gutter could improve the photocatalytic efficiency significantly. The loaded TiO2 photocatalyst attached on glass spring could enhanc the transfer effect. The reactor could utilize direct and scattering ultraviolet light in sunlight sufficiently, and also work well on cloudy day.
