Description of the invention: [Technical field of the invention] The present invention is a kind of fine medium reaction H' system _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The continuous increase in carbon dioxide emissions has made the greenhouse effect increasingly serious. In order to solve the problem of carbon dioxide, many scholars and experts have invested in the research of SiO2 (10) 2), lanthanum carbide ((10), gallium phosphide (GaP) street, and the carbonization of carbon dioxide. A method of producing a product such as CH3〇H). In the process of photocatalytic reduction, 2 and 2 particles are uniformly mixed with the reaction solution to make the suspension 妓^ _ _ ΐΐ efficiently photocatalytic reduction reaction. The incorporation of photocatalyst particles into the reaction system has the advantage of high reaction efficiency, but it is necessary to recover the photocatalyst from the reaction solution, which not only increases the complexity of the process, but also increases the time and cost of the treatment. Another problem is how to provide the photocatalyst with a sufficient area to perform a mass-produced photocatalytic reaction. According to our actual observation, due to the high shielding rate of light by Ti02, υν light is in the suspended water of Ti〇2; in the valley liquid, the penetration distance is only 1~2 cm, and τί〇2 is outside 1~2 cm. There will be no response, making the use efficiency of light greatly reduced. In 1977, Marinangeli and 〇ins proposed the concept of a fiber-optic photocatalyst reactor, attaching a titanium dioxide photocatalyst to the surface of the fiber, allowing the reactant to contact the surface of the titanium dioxide film, and allowing the reaction source to propagate through the fiber, allowing the titanium dioxide photocatalyst and incident light to proceed. Photocatalytic reduction reaction. The optical waveguide photocatalyst reactor can use a light-emitting diode or various light sources as a reaction light source, as described in U.S. Patent Nos. 5,875,384, 5,994,422 and 6,238,630, so that the reaction tank has a small volume and good reaction efficiency. However, the optical waveguide photocatalyst reactor needs to be fixed in the reaction tank, so the mass transfer efficiency of the reactants is low. 5 1357354 According to US Patent Nos. 5480524, 5308458 and 5689798, 'HC Yatmaz et al· (Chemosphere) 42 (2001) 397 ± 403), the rotating reaction bed can use centrifugal force to increase the mass transfer and reaction efficiency of the reactants, and improve the treatment efficiency. Since the reaction light source is installed outside the reactor, if the light transmittance of the reactants When it is low, the photocatalytic reduction reaction of the photocatalyst is poor. In the present invention, it is improved. The optical waveguide photocatalyst reactor and the rotating reaction bed use a light guide plate as a rotating reaction bed, and simultaneously couple the reaction light source into the rotating light guide plate, and use the light guide plate to transmit the reaction light source, so that the photocatalytic reduction reaction can be carried out more efficiently, and at the same time Increasing the mass transfer efficiency of the reactants. SUMMARY OF THE INVENTION In view of the above background, the optical waveguide photocatalyst reactor has poor mass transfer efficiency, while the rotary photocatalyst reactor has poor light transmittance due to reactants, resulting in reaction efficiency. Therefore, the object of the present invention is to use a rotating light guide plate as a reaction bed, and to transmit a reaction light source by using a light guide plate, so that the reaction light source and the photocatalyst material can efficiently perform photocatalytic reduction reaction without being subjected to light transmittance of the reactant. According to the present invention, a light guide plate or a plurality of light guide plates may be used alone as a reaction system according to the requirements of the amount of catalytic reaction. [Embodiment] See the "first to third figures" for the circle of the present invention. The basic structure of the dish-shaped light guide photocatalyst reactor. The reactor comprises a circular dish-shaped light guide plate, and the rotating light guide plate is driven. Motor or drive external force, and reaction light source, etc. The light guide plate can be equipped with or without grooves, cavities or protrusions to enhance the anti-touch rate of the light-guided catalyst reaction, and improve the stability of the light guide plate rotation. The central area of the light plate may or may not have a structure to increase the efficiency of the reaction light source entering the light guide plate. After the light is coupled into the light guide plate, it will be transmitted therein. When the light is finely woven, the various shapes of the stomach are purchased. Picking lining, Tse combined with different kinds of catalysts _ from the source of the efficiency band, for example: titanium dioxide Ϊ catalyst needs to use ultraviolet light or blue-violet light source. The way of the surface light source is divided into two forms. See "Second Picture" and "Figure" for the two different sources of light supply. 『 3 Γ Γ Keep it still, only the photocatalyst itself moves. At this point, the edge of the leading board will directly be added to it. The financial law is directly on the light II? When j5 should be on the cavity, it can have the most convenient operation and maintenance convenience. No need to =. i brother t can directly replace the damaged light source for its maximum advantage #人鲜杂H light edge side and additional k to increase light efficiency. "The === setting and photocatalyst light guide plate - the motion type will be further described later. The invention can utilize one or more light guide plate light touches, and the reaction module can be added with a reaction gas or a flow guiding device of the body to control the reverse reaction and enhance the reaction processing efficiency. ϊίΓ, and “Sixth Diagram” show two demonstrations of coupled passive passives by the shaft side. If there is no such thing as f, it is placed on the light-holding mechanism of the light guide plate by a small light source such as a light-emitting diode, and the reaction optical axis is directly incorporated into the light guide plate. The source of the j can be powered by an electric service or by transmitting a magnetic mouse with electromagnetic energy. 1357354 Using a Reflector As shown in Figure 6, an external light source or sources are used to couple the reactive light source into the light guide. The shape of the light guide plate during operation is not limited to _, and can be changed to a desired shape as required. At the same time, the light guide plate can be rotated not only, but also can be used in various ways, such as vibration 'lion, reciprocating scales, etc., to increase the quality and reaction effect two', to use the light guide plate and related coupling technology, should be in this Embodiments of the scope of the patent ^ According to the figure, the blue light-emitting diode with a main wavelength of 450 nm is light-emitting, and the light is straight into the square of the county. Through the drive motor K, the rotational speed of the circular disc-shaped light guide plate reaches _ (4) ridge minute rotation circle. It can be found that the light contact 1 is incorporated into the human light guide plate, and the light source can be scattered at the edge of the light guide 导-shaped light guide plate. Utilizing a photodiode side guide* edge of the plate and placing the light-receiving limit on the photodiode detection Jt: to prevent the photo-polar detector from being affected by the light-emitting diode source, so that the edge of the light guide plate is scattered The light energy, the fruit shows two: ί in the 4 test chat, the light diode side of the amount of light to get two people: ^. The foot _-shaped guide stage maintains a stable yoke under high-speed rotation. The light source is lightly coupled to the rotating _-shaped light guide plate, which can be used to spread over the light guide plate. The photocatalyst is able to react with the anti-tti reduction reaction, which is not affected by the light transmittance of the reactants, and is an excellent method for the mass transfer efficiency of the reactants at the gate. The preferred embodiment of the present invention is not limited to the content of the present invention, and the equivalent changes and modifications of the patent application scope and invention specification according to the present invention should remain The invention patent covers the scope of 8 1357354.
