为了便于对本发明有更好地理解， 下面先对二氧化钛的相关性作 如下介绍：  In order to facilitate a better understanding of the present invention, the following relates to the correlation of titanium dioxide as follows:
二氧化钛的光催化特性在 1972年由日本藤屿昭教授发现， 至今已 得到广泛的研究和应用。 光催化的基本原理是： 当半导体氧化物 （如 二氧化钛） 纳米粒子受到大于禁带宽度能量的光子照射后， 电子从价 带跃迁到导带， 产生了电子-空穴对， 电子具有还原性， 空穴具有氧 化性， 空穴与氧化物半导体纳米粒子表面的 OH-反应生成氧化性很高 的 OH自由基， 活泼的 OH自由基可以把许多难降解的有机物氧化为 CO: 和 0等无机物。 因此， 纳米二氧化钛不但可广泛用于对燃料废水、 农药废水、 表面活性剂、 含氮有机物、 氯化物、 氟利昂、 工业酸洗废 水以及含油废水等的光催化降解， 把其降解为 C02、 H20和其他 j、分子 无机物； 同时， 还能对空气中的挥发性有机化合物（VOC)， 如甲醛、 苯、 二曱苯、 氨、 二氧化硫、 二氧化氮、 四氯化氮、 三氯乙烯、 四氯 乙烯、 氯仿， 1, 2 -二氯苯， 1 , 3 -二氯苯、 乙苯、 甲苯等进行降解。 The photocatalytic properties of titanium dioxide were discovered by Professor Fujiwara of Japan in 1972 and have been widely studied and applied to date. The basic principle of photocatalysis is: When semiconductor oxide (such as titanium dioxide) nanoparticles are irradiated by photons larger than the band gap energy, electrons transition from the valence band to the conduction band, resulting in electron-hole pairs, and electrons are reductive. The holes are oxidizing, and the holes react with OH- on the surface of the oxide semiconductor nanoparticles to form oxidized OH radicals. The active OH radicals can oxidize many refractory organic substances into CO: and 0 and other inorganic substances. . Therefore, nano-titanium dioxide can be widely used for photocatalytic degradation of fuel wastewater, pesticide wastewater, surfactants, nitrogenous organic compounds, chlorides, freons, industrial pickling wastewater and oily wastewater, and decomposes them into C0 2 , H 20 and other j, molecular inorganic substances; at the same time, also in the air volatile organic compounds (VOC), such as formaldehyde, benzene, diphenylbenzene, ammonia, sulfur dioxide, nitrogen dioxide, nitrogen tetrachloride, trichloro Ethylene, tetrachloroethylene, chloroform, 1,2-dichlorobenzene, 1,3 -dichlorobenzene, ethylbenzene, toluene, etc. are degraded.

锐钛型纳米二氧化钛金属网状骨架结构填料体 10由两部分组成， 一部分是十二面立体金属网状骨架结构海绵填料， 另一部分就是支撑 该填料的骨架结构， 十二面立体金属网状骨架结构海绵填料就填设于 填料骨架结构内。 骨架结构是对十二面立体金属网状骨架结构海绵填 料进行固定和支撑、 十二面立体金属网状骨架结构海绵填料的表面加 载了锐钛型 （Antase,简称 A型）二氧化钛纳米材料， 并形成稳定牢 固的结构， 持久耐用， 不易脱落。  The anatase-type nano-titanium dioxide metal mesh skeleton structure filler body 10 is composed of two parts, one part is a twelve-sided three-dimensional metal mesh structure sponge filler, and the other part is a skeleton structure supporting the filler, and a twelve-sided three-dimensional metal mesh skeleton The structural sponge filler is filled in the filler skeleton structure. The skeleton structure is to fix and support the twelve-dimensional three-dimensional metal mesh structure sponge filler, and the surface of the twelve-dimensional three-dimensional metal mesh skeleton sponge filler is loaded with anatase (A type) titanium dioxide nano material, and Forms a stable and firm structure that is durable and resistant to falling off.
本发明空气过滤装置中采用 tfetalfoam Products Inc · 公司的 固定式纳米二氧化钛 MP-Ti- OS 十二面立体金属网状交连骨架结构填 料为载体，该十二面体金属网状骨架结构填料的气孔数为 4 ppi( 一 英寸长度内由 4个气孔结构）至 100 ppi (一英寸长度内由 100个气 孔结构） ， 形成 900m2/m3〜16000m2/m3的超大比表面积。 因此， 该空气 过滤装置中的填料与污染空气的接触面积大， 过滤有机化合物的效率 高。 在传统的纳米二氧化钛光触媒应用中， 没有固定载体来固定住纳 米二氧化钛粉末， 因此多用胶状物 （如美国 Lamox公司） ， 或磷石 灰（如日本大金空调 Optical Cleale 空气净化器 ） 等将另一种材 料在湿润状态下与纳米二氧化钛混合， 然后涂在网纱上面， 待混合材 料干燥后当作过滤网使用， 该过滤网比表面积只有本发明的 1/ Θ0 ~ 1/200。 The air filter device of the present invention adopts tfetalfoam Products Inc. The fixed nano-titanium dioxide MP-Ti-OS 12-sided three-dimensional metal mesh cross-linked skeleton structure filler is used as a carrier, and the number of pores of the dodecahedral metal mesh skeleton structure filler is 4 ppi (4 pore structures within one inch length) ) to 100 ppi (100 pore structures in one inch length), forming an ultra-large specific surface area of 900 m 2 /m 3 to 16000 m 2 /m 3 . Therefore, the contact area of the filler in the air filtering device with the polluted air is large, and the efficiency of filtering the organic compound is high. In the traditional nano-TiO2 photocatalyst application, there is no fixed carrier to fix the nano-titanium dioxide powder, so the multi-purpose gel (such as the American Lamox company), or the phosphorous lime (such as the Japanese Daikin Air Conditioning Optical Cleale air purifier) will be another. The material is mixed with nano-titanium dioxide in a wet state and then coated on the mesh. After the mixed material is dried, it is used as a filter. The specific surface area of the filter is only 1/Θ0 to 1/200 of the present invention.
本发明的过滤装置可用于任何需要过滤处理挥发性有机化合物 (VOC) 的地方， 如新装修室内、 新车厢内等。 当该装置启动后， 导气 风扇 13 强制进行通风， 带有 VOC 污染物的空气从气体入口端被吸入 过滤装置中， 杂质过滤器 14 的功能是阻挡空气从浮尘等固体颗粒杂 质进入过滤系统中。 紫外线灯管 12 为锐钛型纳米二氧化钛金属网状 骨架结构填料体的光催化作用提供稳定、 持续的紫外光， 该紫外光的 波长为 380nm ~ 250nm之间， 该紫外线光源可以选用中压紫外线灯、 高压汞灯、 黑光灯及紫外线杀菌灯等， 紫外线灯管 12 —般由逆变电 源 DC6V-12V或 AC100- 120V、 AC220V-240V, AC380-440V等配套提供 获得高频电源， 通过根据灯管长度， 灯管功率和紫外线幅照强度的不 同， 其管电压可由 100V至 1500V,或更高 频率一般为 20 hz以上。 带 有 VOC污染物的空气经过纳米二氧化钛金属网状骨架结构填料后， V0C 将被紫外线照射的纳米二氧化钛光催化作用被有效快速地分解，被消 除了 VOC的净化空气将从空气出口端排除，达到空气中 voc 的强效过 滤效果。 而锐钛型纳米二氧化钛在去除各种有害物质时， 其效果并不 会减弱或小时； 只要有持续的紫外线照射， 锐钛型纳米二氧化钛会不 断地产生正价光子空穴进而氧化有机物切断有害无机物的价链结构。  The filtration device of the present invention can be used in any place where filtration of volatile organic compounds (VOC) is required, such as in newly renovated rooms, in new compartments, and the like. When the device is started, the air guiding fan 13 is forcibly ventilated, and air with VOC contaminants is sucked into the filtering device from the gas inlet end, and the function of the impurity filter 14 is to block air from entering the filtering system from solid particles such as floating dust. . The ultraviolet lamp tube 12 provides stable and continuous ultraviolet light for the photocatalysis of the anatase nanometer titanium dioxide metal mesh skeleton structure filler body. The wavelength of the ultraviolet light is between 380 nm and 250 nm, and the ultraviolet light source can be selected from the medium pressure ultraviolet lamp. , high-pressure mercury lamp, black light and ultraviolet germicidal lamp, etc., UV lamp 12 is generally provided by inverter power supply DC6V-12V or AC100-120V, AC220V-240V, AC380-440V, etc. to obtain high-frequency power supply, according to the lamp The length, lamp power and UV intensity may vary from 100V to 1500V, or higher than 20hz. After the air with VOC contaminants passes through the nano-titanium metal mesh-like skeleton structure filler, V0C is effectively and rapidly decomposed by the photocatalytic action of the nano-titanium dioxide irradiated by ultraviolet rays, and the purified air of the VOC is eliminated, and the air is removed from the air outlet end. A powerful filtering effect of voc in the air. However, the effect of anatase-type nano-titanium dioxide on the removal of various harmful substances is not weakened or reduced; as long as there is continuous ultraviolet irradiation, anatase-type nano-titanium dioxide will continuously produce positive-valence photon cavities and oxidize organic substances to cut harmful inorganic substances. The price chain structure of the object.
当然， 本技术领域中的普通技术人员应当认识到， 以上的实施例 仅是用来说明本发明， 而并非用作为对本发明的限定， 只要在本发明 的实质精神范围内， 对以上所述实施例的变化、 变型都将落在本发明 权利要求书的范围内。 Of course, it should be understood by those skilled in the art that the above embodiments are merely illustrative of the invention and are not intended to limit the invention as long as the invention Variations and modifications of the above-described embodiments are intended to fall within the scope of the appended claims.
