Description
技术领域technical field
本实用新型涉及消毒灭菌技术领域,尤其是一种柔性等离子体气体净化装置。The utility model relates to the technical field of disinfection and sterilization, in particular to a flexible plasma gas purification device.
背景技术Background technique
随着人们生活水平的提高,经济技术的不断发展也导致了空气污染越发严重,导致空气中许多污染物已经严重影响到我们的健康水平,为了减少空气污染,我们采用了多种空气净化的方法,这些净化方法一定程度上可以减小空气污染水平,但也存在着诸多问题。在传统的气体净化装置中,主要采用的技术手段如下:With the improvement of people's living standards and the continuous development of economy and technology, air pollution has become more and more serious, resulting in many pollutants in the air that have seriously affected our health. In order to reduce air pollution, we have adopted a variety of air purification methods , these purification methods can reduce the level of air pollution to a certain extent, but there are also many problems. In traditional gas purification devices, the main technical means used are as follows:
1、活性炭净化技术:利用活性炭其本身的多孔结构,提供大量的表面积,使之与气体(杂质)充分接触,从而赋予了活性炭所特有的吸附性能,但研究表明活性炭技术是物理性吸附,效率较低,饱和后会再次释放而造成二次污染。1. Activated carbon purification technology: Utilize the porous structure of activated carbon itself to provide a large amount of surface area, so that it can fully contact with gas (impurity), thus endowing activated carbon with unique adsorption performance, but research shows that activated carbon technology is physical adsorption, efficiency Low, it will be released again after saturation and cause secondary pollution.
2、HEPA滤网技术:净化原理与活性炭类似,同属于物理性吸附,其特点在于达标的HEPA滤网对0.3微米的微粒吸附有效率能达到99%,但这种滤网不可水洗,且设备比较耗电,也需要定期更换滤网。2. HEPA filter technology: The purification principle is similar to that of activated carbon, and it also belongs to physical adsorption. Its characteristic is that the qualified HEPA filter can reach 99% of the adsorption efficiency of 0.3 micron particles, but this filter is not washable, and the equipment It consumes more power, and the filter needs to be replaced regularly.
3、紫外线净化技术:紫外线的消毒杀菌功效较为显著,但不能清除颗粒物和异味,同时,紫外线辐射易对人的眼角膜、皮肤等造成伤害,不能人机共存。3. Ultraviolet purification technology: The disinfection and sterilization effect of ultraviolet rays is relatively significant, but it cannot remove particles and odors. At the same time, ultraviolet radiation is easy to cause damage to human corneas and skin, and cannot coexist with humans and machines.
4、臭氧杀菌技术:利用臭氧本身的高活性,能够有效杀灭细菌、微生物、霉素等,但却不能清除PM2.5等颗粒物,另外,臭氧超标是隐形杀手,其本身具有腐蚀性,同时还可能造成神经中毒、导致哮喘、影响肺功能等。4. Ozone sterilization technology: Utilizing the high activity of ozone itself, it can effectively kill bacteria, microorganisms, toxins, etc., but it cannot remove particulate matter such as PM2.5. In addition, excessive ozone is an invisible killer, which itself is corrosive, and at the same time It may also cause neurotoxicity, cause asthma, and affect lung function.
5、光触媒净化技术:光触媒可以有效的除尘、杀菌,去除甲醛等有机污染,不能消除异味,且本身具有腐蚀性,需要有紫外线的照射才能发生作用(夜间无效),产品寿命短,紫外光对人体有害,不宜人机共存。5. Photocatalyst purification technology: Photocatalyst can effectively remove dust, sterilize, and remove organic pollution such as formaldehyde. Harmful to the human body, it is not suitable for man-machine coexistence.
6、负离子净化技术:利用负离子本身的带电荷性,用以吸附带正电离子的悬浮颗粒,中和成无电荷后沉降,使空气得到净化。其作用是降低空气中的悬浮颗粒物的浓度,而这种办法不能杀死病毒、细菌,也不能分解污染物。6. Negative ion purification technology: use the charged nature of negative ions to absorb suspended particles with positively charged ions, neutralize them to become uncharged, and then settle to purify the air. Its function is to reduce the concentration of suspended particles in the air, and this method cannot kill viruses, bacteria, or decompose pollutants.
而采用等离子体技术可以克服上述的缺点,如专利号201510307671.7的低温等离子体空气净化装置;专利号201410466307.0的等离子体空气净化器;它们虽然可以做到较好的杀菌处理,存在的问题是,上述净化装置设备结构只能在将气体收集在其净化装置内部进行处理,且结构复杂、体积庞大,难以满足便携式的需求。The above-mentioned shortcomings can be overcome by using plasma technology, such as the low-temperature plasma air purification device of Patent No. 201510307671.7; The equipment structure of the purification device can only collect the gas inside the purification device for processing, and the structure is complex and bulky, which is difficult to meet the needs of portability.
