Embodiment Construction
[0018] Referring to the figure, a slant plate 1 is fixed above the water surface, and the angle between the slant plate 1 and the horizontal plane is 10-30°; the fiber braid 2 covers the end of the slant plate 1 away from the water surface, and the fiber One side of the woven fabric 2 hangs down from the edge of the sloping plate and touches the water surface; the surface of the sloping plate 1 is also loaded with catalyst silver phosphate 3 having visible light activity.
[0019] A convex lens 4 is radially divided into two symmetrical parts through its center of circle, and the two parts of the convex lens 4 are linked together by a hinge 5 on one side, but can rotate around the hinge 5; the two parts of the convex lens 4 take the hinge 5 as the axis The rotation of the convex lens is controlled by the heat-sensitive spring 6 whose two ends are respectively fixed on the two parts of the convex lens 4. When the heat-sensitive spring 6 is heated, it expands, and the two parts o...

The invention discloses a reinforced photocatalytic pollutant degradation device which comprises a sloping plate, a fiber fabric and a convex lens, wherein the sloping plate is fixed above the water surface; the fiber fabric is covered on one end of the sloping plate away from the water surface in a sagging mode, and contacts the water surface; a visible-light-active catalyst is supported on the surface of the sloping plate; the convex lens is supported and fixed above the sloping plate through a bracket; and the convex lens is composed of two radially symmetrical parts which are connected into an integral body through a hinge. In the preferable technical scheme, both ends of the convex lens are provided with thermosensitive springs which are used for controlling the two parts of the convex lens to rotate around the hinge; and when the thermosensitive springs are heated to expand, the two parts of the convex lens become an integral body to form the complete convex lens. A continuous-flowing film system can be formed without any power so as to obtain better catalytic effects; and no additional means is needed to separate the catalyst.
Description
technical field [0001] The invention relates to a device for strengthening photocatalytic degradation of pollutants, which belongs to the technical field of sewage treatment in environmental protection. Background technique [0002] Traditional water treatment methods have problems such as low efficiency, high cost, and secondary pollution, and sewage treatment has not been well resolved. The development and application of nanotechnology is likely to completely solve this problem. In 1972, A.Fujishima and K.Honda worked on n-type semiconductor TiO 2 Photocatalytic decomposition of water found on electrode, TiO 2 It has high oxidation activity, good chemical stability, non-toxicity to human body, low cost, no pollution, and wide application range, so it has received the most attention. It is currently the most widely used nano-photocatalytic material, and it is also the most promising green environmental protection type. catalyst. [0003] Studies have shown that nano-TiO...
