Problems solved by technology

At the same time, because long-term exposure to ultraviolet rays is harmful to the human body, most medical photocatalyst excitation instruments use near-ultraviolet visible light. It is difficult to control the uniformity of the photocatalyst under the condition of using visible light to stimulate the photocatalyst reaction, so as to make the photocatalyst effect faster and more ideal as much as possible, which has become a technical problem.

Embodiment 1

[0018] Such as figure 1 As shown, the present embodiment adopts a laser diode as a point light source 11, which can emit laser light in the blue band, and the photocatalyst material adopts nano-titanium dioxide, and carries out photocatalyst reaction in the following manner:

[0019] A reflective layer 12 is arranged behind the point light source 11 , the reflective layer 12 is a parabolic curved surface of revolution, and the point light source 11 is located at the focus of the parabolic curved surface of the reflective layer 12 . The laser light emitted by the laser diode is relatively scattered, because of the characteristics of the rotating parabolic curved surface: all the light emitted from its focal point, after being reflected by the curved surface, becomes a uniform parallel light parallel to the rotation axis, so the laser light emitted by the point light source 11, through After the reflective layer 12 is reflected, it becomes uniform parallel light. Then cast the ...

Embodiment 2

[0021] Such as figure 2 As shown, the present embodiment adopts a gas laser as a point light source 21, which can emit ultraviolet lasers that are considered harmless by the medicine and beauty industries. It does not produce damage such as high temperature, so it is considered harmless to the human body and the environment. The photocatalyst material uses apatite-coated titanium dioxide, which was developed by Professor Nonamyoshi of Chukyo University in Japan using nonamic as a raw material. Apatite has a strong adsorption capacity, and it can also adsorb a large number of bacteria and viruses without a light source. Titanium dioxide can decompose these bacteria. Apatite-coated titanium dioxide has both functions of a binder and a dispersant. Moreover, apatite-coated titanium dioxide can also be excited under light conditions to produce a photocatalyst effect. This new type of material has been widely used as photocatalyst paint, photocatalyst cleaning agent, photocataly...

Abstract

The invention relates to the field of photocatalysts, in particular to a method for exciting a photocatalyst by using laser. In the method, a photocatalyst substance is excited by the laser, and the method sequentially comprises the following steps of: 1, converting the laser generated from a laser light source into parallel and uniform laser beams; and 2, irradiating the photocatalyst substance by using the uniform laser beams, so that the photocatalyst substance is subjected to photocatalyst reaction. In the method, the photocatalyst is excited by the laser, so the speed of the photocatalyst reaction is improved obviously; and the photocatalyst is irradiated by the parallel and uniform laser, so the uniformity of the photocatalyst reaction is improved while the speed of the photocatalyst reaction is improved.

Description

technical field [0001] The invention relates to the field of photocatalysts, in particular to a method for exciting photocatalysts with laser light. Background technique [0002] Generally speaking, the photocatalyst reaction is that the photocatalyst material has a strong catalytic degradation function under the irradiation of ultraviolet light, can decompose organic matter, effectively degrade toxic and harmful substances, can effectively kill a variety of bacteria, and can release bacteria or fungi Toxin decomposition and harmless treatment, but also has the functions of deodorization, anti-fouling, hydrophilic and so on. The greater the energy of ultraviolet light, the stronger the photocatalyst reaction. [0003] The decontamination and sterilization properties of photocatalyst reaction are applied to the fields of medical care and environmental purification, especially tooth bleaching and stain removal. Japanese patent (Patent No.: JP-11-92351, etc.) The method is to...
