Example Embodiment

[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

[0020] As shown in Figure 1: It includes a plexiglass cylinder 1, in which two aluminum mesh cylinders 2 of the same height with a reducing suit are installed. Between the two aluminum mesh cylinders 2 are optical fiber bundles 3 and three-dimensional titanium dioxide fibers Layer 4 composite layer.

[0021] Among them, 3 is divided into two parts, namely a spiral part and a straight part. At the end of the spiral, the optical fiber is guided to the upper end surface of the organic glass tube 1 in a straight line; the production method of the three-dimensional titanium dioxide fiber layer 4 is: the viscosity is 4-6Pa· The titanium dioxide precursor spinning solution of s is poured into the centrifuge tube, the centrifuge tube is fixed on the rotating mold, the rotating mold is turned on, the speed is 6000r / min, and it is translated and moved along the central axis of th...

Abstract

This invention discloses a three-dimensional TiO2 fiber layer photocatalytic water purifier. The water purifier utilizes TiO2 fibers as the photocatalyst, and optical fibers as the light guiding medium. The optical fibers can guide sunlight into the water purifier, where sunlight acts as the activating source of TiO2 fibers so that wastewater and catalyst react under sunlight activation to remove impurities. The water purifier comprises an organic glass outer cylinder, with a water inlet at the bottom of one side, and a water outlet at the top of the other side. At least two sleeved aluminum mesh cylinders with the same height and different diameters are set in the organic glass outer cylinder, and the interlayer in between is composed of optical fiber beam and three-dimensional TiO2 fiber layer. A light focusing device is set at the top of the outer surface of the organic glass outer cylinder.

Description

technical field [0001] The invention relates to a photocatalytic water purification treatment device, in particular to a three-dimensional titanium dioxide fiber layer photocatalytic water purification treatment device. Background technique [0002] Photocatalytic oxidation technology occupies an important position in the fields of environmental protection and chemical engineering because of its simple process, easy control of operating conditions, rapid and effective degradation of pollutants and no secondary pollution. Photocatalysts used for photocatalytic degradation of environmental pollutants are mostly n-type semiconductor materials, among which titanium dioxide has become the most important photocatalyst because of its high activity, good stability and harmlessness to human body. At present, there are insurmountable defects in the application forms of titanium dioxide such as nanopowder, thin film and supported type. It is difficult to separate and recycle the nanop...
