Embodiment 1
[0036] Such as figure 1 , 2 As shown, a multi-layer plate frame type floating photocatalytic water purification device includes a visible light catalytic unit and an ultraviolet photocatalytic unit, and the visible light catalytic unit and the ultraviolet photocatalytic unit are connected by connecting ribs 6; The catalytic unit includes a visible photocatalytic layer 4, and the ultraviolet photocatalytic unit includes a layer of ultraviolet photocatalytic layer 5;
[0037] The visible photocatalytic layer 4 includes a base fabric 2 and a plate frame 3, the base fabric 2 is loaded with a carbon nitride visible light catalytic material, and the base fabric 2 is fixedly arranged on the plate frame 3;
[0038] The ultraviolet photocatalytic layer 5 includes another base fabric 2 and another plate frame 3, the other base fabric 2 is loaded with titanium dioxide ultraviolet photocatalytic material, and the other base fabric 2 is fixedly arranged on the other plate frame 3;
[003...
Embodiment 2
[0043] As described in Example 1, the difference is:
[0044] The plate frame 3 is only arranged around the base fabric 2 . This setting is beneficial to reduce the weight of the plate frame 3 itself, while protecting the base fabric 2 at the same time. The floating assist device 1 is a floating rod, which is fixedly connected to the plate frame 3 by binding the floating rod 7 with cable ties.
[0045] In this embodiment, the mesh gap between the base fabric 2 and the frame 3 in the visible photocatalytic layer 4 is 1 cm, and the mesh gap between the base fabric 2 and the frame 3 in the ultraviolet photocatalytic layer 5 is 0.4 cm. The distance between the visible photocatalytic layer 4 and the ultraviolet photocatalytic layer 5 is 20 cm.
Embodiment 3
[0047] As described in Example 1 or 2, the difference is:
[0048] A baffle is vertically arranged around the said plate frame 3, and the baffle is vertically arranged with the plate frame, and the height of the baffle is 1 cm.
[0049] In this embodiment, the mesh gap between the base fabric 2 and the frame 3 in the visible photocatalytic layer 4 is 1.5 cm, and the mesh gap between the base fabric 2 and the frame 3 in the ultraviolet photocatalytic layer 5 is 0.7 cm. The distance between the visible photocatalytic layer 4 and the ultraviolet photocatalytic layer 5 is 40 cm.
