技术领域technical field
本实用新型涉及空气净化装置技术领域，尤其是涉及一种电场辅助室内空气净化装置。The utility model relates to the technical field of air purification devices, in particular to an electric field assisted indoor air purification device.
背景技术Background technique
在自然通风的空旷室外，空气中的污染物一般不会影响人们的身体健康。但随着居住条件提高，家庭装修普遍化，通常处于密闭状态的建筑物内，各种污染物浓度过高，已严重影响着人们的身体健康。甲醛等挥发性有机化合物（Volatile Organic Compounds）在室内空气中的存在，使传统机械过滤式空气净化装置失效，导致室内空气品质恶化，也使得新型空气净化装置具备了重要的研发价值和广阔的市场空间。In a naturally ventilated open room, the pollutants in the air generally do not affect people's health. However, with the improvement of living conditions and the generalization of home decoration, the concentration of various pollutants is too high in buildings that are usually in a closed state, which has seriously affected people's health. The presence of formaldehyde and other volatile organic compounds (Volatile Organic Compounds) in indoor air makes traditional mechanical filter air purification devices ineffective, leading to deterioration of indoor air quality, and also makes new air purification devices have important research and development value and a broad market space.
活性炭材料的微孔结构，导致其比表面积在1000m2/g以上，所以用活性炭吸附去除室内污染是应用最广泛的一种方法。目前在生活中用活性炭包来吸附空气中的甲醛、氨、苯、二甲苯、氡等有害气体，可快速消除装修异味，对于居室、家具衣橱、书柜、鞋柜、鞋内、冰箱、卫生间、地板、鱼缸、汽车、空调、电脑、办公、宾馆及娱乐场所等，有很好的效果。在环境保护、工业生产和日常生活中，活性炭也由于吸附性能优越，被大量使用。活性炭吸附是一个物理过程，在吸附饱和后若能进行脱附并恢复活性，可达到重复使用目的。制备1公斤活性炭，需消耗8公斤木材或8公斤原煤，所以活性炭的再生可以大量减少资源消耗，减少大气污染，降低能源浪费，经济效益明显。The microporous structure of activated carbon material leads to its specific surface area above 1000m 2 /g, so using activated carbon to adsorb and remove indoor pollution is the most widely used method. At present, activated carbon packs are used in daily life to absorb harmful gases such as formaldehyde, ammonia, benzene, xylene, and radon in the air, which can quickly eliminate decoration odors. , floors, fish tanks, automobiles, air conditioners, computers, offices, hotels and entertainment venues, etc., have very good results. In environmental protection, industrial production and daily life, activated carbon is also widely used due to its superior adsorption performance. Activated carbon adsorption is a physical process. After the adsorption is saturated, if it can be desorbed and the activity can be restored, it can be reused. To prepare 1 kg of activated carbon, it needs to consume 8 kg of wood or 8 kg of raw coal, so the regeneration of activated carbon can greatly reduce resource consumption, reduce air pollution, reduce energy waste, and have obvious economic benefits.
活性炭的再生活化，一般为在不破坏活性炭原有结构前提下，用物理或化学方法将吸附于活性炭上的吸附质予以去除，即可恢复吸附性能从而重复使用。目前常用的高温蒸汽再生法和加热炭化再生法，具备再生效率高、应用范围广的优点，但在再生过程中活性炭质量损耗大，再生后活性炭吸附能力下降，再生系统需外加热源加热、装备复杂且无法实现连续的活性炭吸附作用。为克服上述缺陷，国内外的研究者已经研究了诸如生物再生法、湿式氧化再生法、溶剂再生法、电化学再生法、催化再生法等活性炭活化技术。但这些技术往往主要针对工业应用领域，其系统复杂，所以无法直接应用在室内空气净化设备中。The regeneration and activation of activated carbon is generally to remove the adsorbate adsorbed on the activated carbon by physical or chemical methods without destroying the original structure of the activated carbon, so that the adsorption performance can be restored and reused. At present, the commonly used high-temperature steam regeneration method and heating carbonization regeneration method have the advantages of high regeneration efficiency and wide application range, but the mass loss of activated carbon is large during the regeneration process, and the adsorption capacity of activated carbon decreases after regeneration. The regeneration system requires external heat source heating and complex equipment. And can not realize continuous activated carbon adsorption. In order to overcome the above defects, researchers at home and abroad have studied activated carbon activation technologies such as biological regeneration, wet oxidation regeneration, solvent regeneration, electrochemical regeneration, and catalytic regeneration. However, these technologies are often mainly aimed at industrial applications, and their systems are complex, so they cannot be directly applied to indoor air purification equipment.
