Among them, photocatalysis has been widely studied because of its advantages of high efficiency, low consumption, non-toxic and harmless, and bacteria elimination. .
光催化空气净化技术基于半导体理论，其催化降解污染物的原理为：在光源照射下，光催化材料吸收的光子能量大于或等于其禁带宽度时，会产生空穴一电子对，当空穴一电子对移动到催化剂表面时，与吸附在催化剂表面的有害气体分子发生氧化还原反应，最终生成无毒无害的水和二氧化碳等物质。经专利检索发现，空气净化净化技术的专利有：Photocatalytic air purification technology is based on the theory of semiconductors. The principle of its catalytic degradation of pollutants is: under the irradiation of a light source, when the photon energy absorbed by the photocatalytic material is greater than or equal to its forbidden band width, a hole-electron pair will be generated. When the hole-electron pair When the electron pairs move to the surface of the catalyst, they undergo redox reactions with harmful gas molecules adsorbed on the surface of the catalyst, and finally generate non-toxic and harmless substances such as water and carbon dioxide. According to the patent search, the patents of air purification and purification technology include:
中国专利号1288755A，名称为：多层结构的光催化空气净化网及其制备方法。该专利中采用网状结构设计，并未安装箱式外壳，使得该发明不具有密闭性，且使其在实际使用中不易搬运与安装。内部结构为多层结构，使空气通过阻力增大，耗能高，净化效率低。Chinese Patent No. 1288755A, titled: multi-layer photocatalytic air purification net and its preparation method. The patent adopts a mesh structure design and does not install a box-type casing, which makes the invention not airtight, and makes it difficult to carry and install in actual use. The internal structure is a multi-layer structure, which increases the air passage resistance, high energy consumption, and low purification efficiency.
中国专利号103551032A，名称为：立体式光催化空气净化器。该专利采用封闭式结构，封闭的外壳为方形，外观不美观，封闭的外壳没有设置可拆卸的前盖，安装后拆换内部零件不易。内部结构为多层平行的板状结构，使空气阻力变大。Chinese Patent No. 103551032A, titled: Stereo Photocatalytic Air Purifier. This patent adopts a closed structure, the closed shell is square, and the appearance is not beautiful. The closed shell is not provided with a detachable front cover, and it is not easy to replace the internal parts after installation. The internal structure is a multi-layer parallel plate structure, which increases the air resistance.
中国专利号1533830A，名称为：光催化净化空气的装置及方法。该专利中的过滤材料为多孔陶瓷、金属网及玻璃纤维，对颗粒物有过滤效果，但是对于挥发性有机物的吸附效果很弱，在光催化反应中产生的副产物会排到环境中，造成二次污染，在室内环境如实验室、地铁、工厂等封闭室内环境使用时有二次污染物存在对人体健康产生危害的风险。Chinese Patent No. 1533830A, titled: Device and method for photocatalytic air purification. The filter material in this patent is porous ceramics, metal mesh and glass fiber, which has a filtering effect on particulate matter, but has a weak adsorption effect on volatile organic compounds, and the by-products produced in the photocatalytic reaction will be discharged into the environment, causing secondary pollution. Secondary pollution, when used in indoor environments such as laboratories, subways, factories and other closed indoor environments, secondary pollutants may pose a risk of harm to human health.
中国专利号1775294A，名称为：空气净化部件及空气净化单元。该专利运用了磷灰石与光催化剂相结合，可以有效吸附病毒与细菌，但未加入紫外光源，使光催化效率低下，无法有效地处理空气中的挥发性有机物。Chinese Patent No. 1775294A, titled: Air Purification Component and Air Purification Unit. This patent uses the combination of apatite and photocatalyst, which can effectively adsorb viruses and bacteria, but does not add ultraviolet light source, so that the photocatalytic efficiency is low, and the volatile organic compounds in the air cannot be effectively treated.
因此现有的光催化空气净化装置，有些没有采用封闭结构，封闭式的装置外壳多为方形，不美观，且不易拆装与搬运。内部结构多为平行的多层平板或网状结构，使空气阻力过大。还有有产生二次污染物、对挥发性有机物净化效率低等缺点，在室内环境如实验室、地铁、工厂等封闭室内环境使用时易产生二次污染。Therefore, some of the existing photocatalytic air purification devices do not adopt a closed structure, and the closed device shells are mostly square, which is not beautiful, and is not easy to disassemble and carry. The internal structure is mostly parallel multi-layer flat plate or mesh structure, which makes the air resistance too large. There are also disadvantages such as secondary pollutants and low purification efficiency for volatile organic compounds. When used in indoor environments such as laboratories, subways, factories and other closed indoor environments, secondary pollution is easy to occur.

所述空气净化装置外壳，其径向横截面下方为方形，上部为两端顶角为圆角。The housing of the air purification device has a square radial cross-section below and rounded top corners at both ends.
所述网状薄板的径向横截面下方为方形，上部为两端顶角为圆角，大小与空气净化装置外壳一致。前后两个网状薄板结构分别与前端盖和空气净化装置外壳后部相连。网状薄板结构，其多孔孔型为方形，均匀分布在薄板上。The radial cross-section of the mesh thin plate is square at the bottom, and the top corners at both ends are rounded at the top, and the size is consistent with the housing of the air purification device. The front and rear two mesh thin plate structures are respectively connected with the front cover and the rear part of the shell of the air purification device. Reticulated thin plate structure, its porous shape is square, evenly distributed on the thin plate.
所述十字形结构的光催化平板为两块垂直相交的板状光催化平板，径向截面为十字型，且四条边与空气净化装置外壳内侧相连，长度与空气净化装置外壳相同。The cross-shaped photocatalytic flat plate is two vertically intersecting plate-shaped photocatalytic flat plates, the radial cross-section is cross-shaped, and the four sides are connected to the inner side of the air purification device shell, and the length is the same as the air purification device shell.

在十字形结构的光催化平板外表面设置有二氧化钛光催化剂层。A titanium dioxide photocatalyst layer is arranged on the outer surface of the cross-shaped photocatalytic flat plate.
本发明的箱式光催化空气净化装置特别适用于家庭、实验室、地铁或工厂等的封闭室内环境中。The box-type photocatalytic air purification device of the present invention is particularly suitable for closed indoor environments such as families, laboratories, subways or factories.
与现有技术相比,箱式光催化空气净化装置有如下独特的设计：Compared with the existing technology, the box-type photocatalytic air purification device has the following unique design:
箱式光催化空气净化装置采用了箱式的封闭外壳，使过滤、吸附和光催化反应过程保持在封闭的空间内进行，避免了光催化反应产生的副产物没有通过吸附就散播到空气中，避免了二次污染的可能性。空气净化装置外壳底部为方形，使装置易于在平面上放置及固定，增加了使用过程中的安全性，顶部的圆角型设计使箱式外观美观，使用过程中不易产生刮碰。The box-type photocatalytic air purification device adopts a box-type closed shell to keep the process of filtration, adsorption and photocatalytic reaction in a closed space, avoiding the by-products generated by the photocatalytic reaction from spreading into the air without adsorption, avoiding the possibility of secondary pollution. The bottom of the shell of the air purification device is square, which makes it easy to place and fix the device on a flat surface, increasing the safety during use. The rounded corner design on the top makes the box look beautiful, and it is not easy to scratch during use.
箱式光催化空气净化装置内部采用独特的十字形结构的光催化平板，现有的专利主要以多层平行叠加的平板结构设计为主，这种设计使空气通过时阻力增大，增大了设备的能耗，而十字形结构的光催化平板为两块垂直相交的平板结构，将箱式光催化空气净化装置内部分成四个部分，空气流动方向与平板平面平行，相比垂直通过大大减小了阻力，且这种设计使空气与光催化剂层有非常大的接触面积，使空气净化的效率得到提高。The box-type photocatalytic air purification device uses a unique cross-shaped photocatalytic flat plate inside. The existing patents mainly focus on the multi-layer parallel stacked flat plate structure design. This design increases the resistance when the air passes through, and increases the The energy consumption of the equipment, and the cross-shaped photocatalytic plate is two vertically intersecting plate structures, which divides the box-type photocatalytic air purification device into four parts, and the air flow direction is parallel to the plate plane, which is greatly reduced compared with vertical passage The resistance is reduced, and this design makes the air and the photocatalyst layer have a very large contact area, so that the efficiency of air purification is improved.
箱式光催化空气净化装置的前端盖设计可以拆卸，使得拆卸、更换内部过滤吸附层与十字形结构的光催化平板等结构更加便捷。过滤吸附层的活性炭纤维随着使用时间的增加，逐渐趋于吸附饱和，并随着不断脱纤，其过滤吸附性能会逐渐降低，内部的光催化剂虽然使用寿命更长，但也面临失活的风险，需要在一定时间内更换。前端盖的设计使更换上述部件相比其他发明更加便捷。The front cover design of the box-type photocatalytic air purification device can be disassembled, which makes it more convenient to disassemble and replace the internal filter adsorption layer and the cross-shaped photocatalytic flat plate. The activated carbon fiber in the filter adsorption layer gradually tends to adsorption saturation with the increase of use time, and with continuous defiberization, its filter adsorption performance will gradually decrease. Although the internal photocatalyst has a longer service life, it also faces the risk of deactivation. risk and need to be replaced within a certain period of time. The design of the front end cover makes it easier to replace the above parts than other inventions.
箱式光催化空气净化装置有效解决了活性炭纤维吸附饱和后失效的问题，以及光催化反应带来的二次污染问题，提高了对空气污染物的净化效率，为挥发性有机污染物的净化提供了一种切实可行的方法，箱式光催化空气净化装置是提供高效利用光能、持续高效稳定运转的多功能空气净化系统。The box-type photocatalytic air purification device effectively solves the problem of failure of activated carbon fibers after adsorption and saturation, as well as the secondary pollution caused by photocatalytic reactions, improves the purification efficiency of air pollutants, and provides a source for the purification of volatile organic pollutants. A practical method is proposed.
