Description
技术领域technical field
本实用新型涉及空气净化技术领域，尤其涉及一种复合空气净化过滤结构及空气净化滤芯。The utility model relates to the technical field of air purification, in particular to a composite air purification filter structure and an air purification filter core.
背景技术Background technique
随着人们生活水平的提高，造成了环境污染问题逐渐加剧。尤其是进入秋冬季节，随着国人的集体供暖以及工业废弃物的排放，导致了环境中充斥着大量的颗粒物，引起雾霾现象，对室内环境中的空气质量造成了影响。常规的室内空气净化机器中往往搭配具有去除颗粒物功能的中效或者高效的PP熔喷的无纺布材料，对室内环境中的颗粒物进行拦截，达到去除室内环境中的灰尘颗粒物以及细菌的作用。然而，对于雾霾频发的季节，去除颗粒物的HEPA滤网的去除功能有限，且容尘量极容易达到饱和状态，导致过滤网被灰尘堵塞失效。因此，迫切需要具有有效去除室内颗粒物污染物的空气净化滤芯，实现对环境的快速有效净化。With the improvement of people's living standards, the problem of environmental pollution has gradually aggravated. Especially in autumn and winter, with the collective heating of Chinese people and the discharge of industrial waste, the environment is filled with a large amount of particulate matter, causing smog and affecting the air quality in the indoor environment. Conventional indoor air purification machines are often equipped with medium-efficiency or high-efficiency PP melt-blown non-woven materials with the function of removing particles to intercept particles in the indoor environment and achieve the effect of removing dust particles and bacteria in the indoor environment. However, in the season of frequent smog, the HEPA filter for removing particulate matter has limited removal function, and the dust holding capacity can easily reach saturation, causing the filter to become clogged with dust and fail. Therefore, there is an urgent need for an air purification filter element that can effectively remove indoor particulate matter pollutants, so as to realize rapid and effective purification of the environment.
在过滤网中增加负离子粉成分，能够增加去除颗粒物污染物的效果。但是常规的做法是将其粉末直接胶粘到纤维表面，这样容易造成负离子粉末用量多，不利于其均匀分散使用。而且使用过量增加整个过滤网的风阻，导致应用范围受限。Adding negative ion powder components in the filter can increase the effect of removing particulate pollutants. However, the conventional method is to directly glue the powder to the surface of the fiber, which is easy to cause a large amount of negative ion powder, which is not conducive to its uniform dispersion and use. Moreover, excessive use increases the wind resistance of the entire filter screen, resulting in limited application range.
针对该问题，本案提出了一种新的复合空气净化过滤结构。该滤芯可以广泛应用在空气净化器、空调、新风通风净化装置、机动车内滤器以及工厂污染环境治理中。In response to this problem, this case proposes a new composite air purification filter structure. The filter element can be widely used in air purifiers, air conditioners, fresh air ventilation and purification devices, motor vehicle interior filters and factory pollution environment treatment.
