Description

Technical Field

[0001] The utility model relates to the technical field of photocatalysts, in particular to a photocatalyst reactor with a portable semiconductor light source. Background Art

[0002] Photocatalysts are a general term for a class of semiconductor materials represented by titanium dioxide, which do not change themselves under light irradiation but can promote chemical reactions and have catalytic functions. As a photocatalyst, titanium dioxide absorbs ultraviolet rays in sunlight or lighting sources and undergoes oxidation-reduction reactions under the excitation of ultraviolet energy, forming strongly oxidizing hydroxyl radicals and superoxide anion radicals on the surface. These radicals can decompose harmful substances (various organic compounds and some inorganic substances) and microorganisms in the air into harmless titanium dioxide and water, thereby achieving the purposes of purifying air, sterilizing, deodorizing, etc., which is the photocatalysis technology.

[0003] In the existing technology, photocatalysts all use ultraviolet light to irradiate titanium dioxide photocatalyst materials to generate hydroxyl substances for purifying air. They belong to the category of air purification devices. Most products use UV lamp panels, whose main functions are to generate hydroxyl substances and ozone, and can only be used for disinfection functions and cannot be applied to the medical field. Summary of the Utility Model

[0004] To solve the problems in the above background art, the utility model provides a photocatalyst reactor with a portable semiconductor light source, which can avoid generating ozone harmful to the body and provide hydroxide ions and can be applied to the medical field.

[0005] The solution adopted by the utility model to solve its technical problems is: a photocatalyst reactor with a portable semiconductor light source, including a reactor body, the reactor body includes a lamp panel and a semiconductor lamp panel arranged on the lamp panel. A photocatalyst reaction net is arranged at one end of the lamp panel close to the semiconductor tube panel, and a photocatalyst cavity is formed between the lamp panel and the photocatalyst reaction net.

[0006] By adopting the above solution, it can avoid generating ozone harmful to the body, provide hydroxide ions, and the semiconductor lamp panel has better mechanical properties and longer service life than the traditional glass lamp panel.

[0007] Further, a metal cover is arranged outside the photocatalyst reaction net, and a reaction cavity is formed between the photocatalyst reaction net and the metal cover. A grid-shaped metal net is connected through the photocatalyst cavity and the reaction cavity.

[0008] By adopting the above solution, adding the metal net and the metal cover can effectively reduce the number of positive ions, thereby increasing the number of hydroxide ions.

[0009] Further, a plurality of air outlets are arranged on the metal net, and an air inlet is arranged at one end of the reactor body far from the metal net.

[0010] Furthermore, the air inlet is provided with a jack for inserting a blower, and is fixedly connected to the blower through the jack.

[0011] By adopting the above solution, the function of adding the blower is to accelerate the flow of electrons, and to avoid the recombination with the hot holes on the photocatalyst as much as possible, so as to prevent the reduction of the number of electrons.

[0012] Furthermore, a plurality of semiconductor lamp boards are provided.

[0013] By adopting the above solution, the irradiation intensity of the ultraviolet light source is increased, and the purification effect of photocatalysis is better.

[0014] Furthermore, the metal cover and the metal mesh are made of aluminum alloy material.

[0015] By adopting the above solution, aluminum alloy has higher strength and rigidity, can better resist external impact and compression, has excellent electrical conductivity, low resistance, and is beneficial to absorbing positive ions.

[0016] In summary, the beneficial effects of the present utility model are as follows: by providing a photocatalyst reactor of a portable semiconductor light source, the generation of ozone harmful to the body is avoided. The semiconductor lamp board has better mechanical properties and longer service life than the traditional glass lamp board. Adding a metal mesh and a metal cover in the air outlet and the reaction chamber can effectively reduce the number of positive ions, thereby increasing the number of hydroxide ions. The metal cover and the metal mesh made of aluminum alloy material are beneficial to absorbing positive ions, reducing the probability of electrons being neutralized or recombined in the reactor, increasing the proportion of the number of electrons, and further increasing the number of hydroxide ions.

[0021] In order to make the content of the present utility model easier to be clearly understood, the present utility model will be further described below according to specific embodiments in conjunction with the accompanying drawings.

[0022] It should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. used herein is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0023] Unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0024] As Figures 1 to 2 shown, a photocatalyst reactor of a portable semiconductor light source includes a reactor body. The reactor body includes a lamp board 1 and a semiconductor lamp board 2 provided on the lamp board 1. The effective length of the semiconductor lamp board 2 is 222 nm to 365 nm, and its effective wavelength is 222 to 255 nm. It can be seen that the advantages of this semiconductor light source are: small volume, low power consumption, concentrated output light intensity. One end of the lamp board 1 outside and close to the semiconductor tube board is provided with a photocatalyst reaction net 3. The lamp board 1 and the photocatalyst reaction net 3 form a photocatalyst cavity 4. When the semiconductor lamp board 2 is lit, ultraviolet light is emitted and shines on the photocatalyst reaction net 3. The electrons with higher activity on the photocatalyst material will break away from the photocatalyst material and combine with oxygen molecules in the air to form hydroxide ions, and it can be applied in the medical field.

[0025] A metal cover 5 is provided outside the photocatalyst reaction net 3, and the photocatalyst reaction net 3 and the metal cover 5 form a reaction cavity 6. The photocatalyst cavity 4 and the reaction cavity 6 are connected through a grid-shaped metal net 7.

[0026] The metal mesh 7 is provided with a plurality of air outlets 8, and an air inlet 9 is provided at one end of the reactor body away from the metal mesh 7. The positions of the air inlet 9 and the air outlet are arranged completely independently and separately to avoid the intersection of dirty air and fresh air, and to promote air flow in a scientific airflow organization manner. When the semiconductor light board 2 is lit, ultraviolet light is emitted to shine on the photocatalyst reaction net 3, and the electrons with higher activity on the photocatalyst material will be separated from the photocatalyst material, and combined with the oxygen molecules in the air to form hydroxyl ions. At the same time, the wind from the air inlet 9 blows to the air outlet 8. Since the air at the air inlet 9 contains a large amount of positive ion substances, the positive ions and the electrons escaping from the photocatalyst material are easily neutralized due to their positive and negative charges. Therefore, a metal cover 5 with low internal resistance and high conductivity is added outside the photocatalyst reaction net 3, and the metal mesh 7 of the air outlet 8 is used to absorb positively charged positive ions, which reduces the number of positive ions and increases the ratio of the number of electrons, thereby increasing the number of electrons combined with oxygen molecules, thereby increasing the number of hydroxyl ions, and then improving the air purification efficiency.

[0027] A socket 81 for inserting a fan is provided in the middle of the air inlet 9, which is fixedly connected to the fan through the socket 81. The photocatalytic purification process is achieved by the fan driving the air to circulate continuously through the photocatalyst reaction layer network illuminated by the light source, while accelerating the flow of electrons and trying to avoid recombination with the heat holes on the photocatalyst, thereby reducing the number of electrons.

[0028] In this embodiment, there are multiple semiconductor lamp boards 2, which are evenly distributed on the lamp board 1. When considering improving the photocatalytic purification effect of the reactor, this aspect is taken into consideration, that is, increasing the irradiation intensity of the ultraviolet light source, so that the photocatalytic purification effect is better.

[0029] The metal cover 5 and the metal mesh 7 in this embodiment are made of aluminum alloy. Aluminum alloy has higher strength and rigidity, can better resist external impact and pressure, has excellent electrical conductivity, and has low resistance, which is conducive to absorbing positive ions.

[0030] In summary, the beneficial effects of this embodiment are as follows: this embodiment avoids the production of ozone that is harmful to the body by setting up a portable semiconductor light source photocatalyst reactor. The use of semiconductor light sources has better mechanical properties and longer life than traditional glass lamp panels. Adding metal meshes and metal covers in the air outlet and the reaction chamber can effectively reduce the number of positive ions, thereby increasing the number of hydroxide ions. The use of aluminum alloy materials for the metal cover and the metal mesh is conducive to absorbing positive ions, reducing the probability of electrons being neutralized or recombined in the reactor, increasing the proportion of the number of electrons, and further increasing the number of hydroxide ions.

[0031] The above-described embodiments are only the preferred embodiments of the present utility model, and the protection scope of the present utility model cannot be limited thereby. Any non-substantial changes and modifications made by those skilled in the art based on the present utility model shall fall within the protection scope of the present utility model.
