Description

一种用于新风系统的纤维过滤材料
技术领域
本发明涉及空气过滤领域，具体的讲是一种用于新风系统的纤维过滤材料。
背景技术
新风系统是由送风系统和排风系统组成的一套独立空气处理系统，它分为管道式新风系统和无管道新风系统俩种。管道式新风系统由新风机和管道配件组成，通过新风机净化室外空气导入室内，通过管道将室内空气排出；无管道新风系统由新风机组成，同样由新风机净化室外空气导入室内，同时由呼吸宝将室内污浊空气排出。相对来说管道式新风系统由于工程量大更适合工业或者大面积办公区使用，而无管道新风系统因为安装方便，更适合家庭使用。
空气污染已经被列为世界三大污染之一，危害和影响都非常大，吸入低质量空气很容易损害身体健康，诱发各种疾病。采用过滤材料对空气进行过滤，特别是新风系统中使用过滤材料过滤是十分普及的。
现有过滤材料多使用无纺棉进行过滤，过滤效果一般，在现在PM2.5经常超标的情况下，原有的过滤材料很难发挥用处。
因此，需要一种结构简单，能够提高新风系统过滤效果，大幅降低倒入空气中PM2.5含量的一种用于新风系统的纤维过滤材料。
发明内容
本发明针对现有过滤材料多使用无纺棉进行过滤，过滤效果一般，在现在PM2.5经常超标的情况下，原有的过滤材料很难发挥用处的问题，提供一种用于新风系统的纤维过滤材料。
本发明解决上述技术问题，采用的技术方案是，一种用于新风系统的纤维过滤材料，从上至下包括第一层玻璃纤维层、第二层化工合成纤维层、第三层植物纤维层和第四层细菌纤维层，所述第一层与第二层之间粘结有热熔胶，所述第二层与第三层之间粘结有热熔胶，所述第三层与第四层之间粘结有热熔胶。
可选的，一种用于新风系统的纤维过滤材料，热熔胶层的原料为聚烯烃树脂或PP熔喷纤维。
进一步的，一种用于新风系统的纤维过滤材料，玻璃纤维层、化工合成纤维层、植物纤维层和细菌纤维层厚度比例为3:2:2:1。
进一步的，一种用于新风系统的纤维过滤材料，玻璃纤维层按照重量份的原料组成:玻璃纤维30-50份、氧化锌5-10份、活性炭5-10份、四氧呋喃3-5份。
可选的，玻璃纤维层按照重量份的原料组成:玻璃纤维35-45份、氧化锌7-9份、活性炭6-8份、四氧呋喃3-5份。
可选的，玻璃纤维层按照重量份的原料组成:玻璃纤维40份、氧化锌8份、活性炭7份、四氧呋喃4份。
可选的，化工合成纤维层按照重量份的原料组成:粘纤20-40份、氧化锌5-10份、活性炭5-10份、聚丙烯3-5份。
可选的，化工合成纤维层按照重量份的原料组成:粘纤25-35份、氧化锌7-9份、活性炭6-8份、聚丙烯3-5份。
可选的，化工合成纤维层按照重量份的原料组成:粘纤30份、氧化锌8份、活性炭7份、聚丙烯4份。
可选的，植物纤维层按照重量份的原料组成:竹纤维10-20份、木质纤维10-20份、氧化锌5-10份、活性炭5-10份、异丙醇3-5份。
可选的，植物纤维层按照重量份的原料组成:竹纤维12-18份、木质纤维12-18份、氧化锌5-10份、活性炭5-10份、异丙醇3-5份。
可选的，植物纤维层按照重量份的原料组成:竹纤维15份、木质纤维15份、氧化锌8份、活性炭7份、异丙醇4份。
可选的，细菌纤维层按照重量份的原料组成:细菌纤维素纤维5-10份、氧化锌5-10份、活性炭5-10份、磷酸二氢钾3-5份。
可选的，细菌纤维层按照重量份的原料组成:细菌纤维素纤维7-9份、氧化锌6-8份、活性炭7-9份、磷酸二氢钾3-5份。
可选的，细菌纤维层按照重量份的原料组成:细菌纤维素纤维8份、氧化锌7份、活性炭8份、磷酸二氢钾4份。
进一步的，竹纤维与木质纤维重量份比例为1:1。
这样设计的目的在于，由于第一层采用玻璃纤维层为过滤材料提供了骨架结构，起到了支撑作用，且玻璃纤维层能够起到一定的过滤效果。
同时，将玻璃纤维层与化工合成纤维层通过热熔胶进行粘合，可以提高过滤效果，化工合成纤维层对空气中的水分子进行吸附，使通过新风系统进入室内的空气变得干燥，可以大幅降低空气中霉菌存活率。
同时，植物纤维层中木质纤维与竹纤维的宽度多在50-60um的区间，可以将一部分小颗粒物体进行剥离。
同时，由细菌素制得的纤维素带状束宽为70-80nm，其直接远远小于玻璃纤维、化工纤维和植物纤维，具有高透气性，可以将其他过滤材料很难过滤的干净的物质进行过滤，大幅降低导入室内的PM2.5含量。
本发明的有益效果至少是以下之一：
1.通过第一层采用玻璃纤维层为过滤材料提供了骨架结构，起到了支撑作用，且玻璃纤维层能够起到一定的过滤效果。
2.通过，将玻璃纤维层与化工合成纤维层通过热熔胶进行粘合，可以提高过滤效果，化工合成纤维层对空气中的水分子进行吸附，使通过新风系统进入室内的空气变得干燥，可以大幅降低空气中霉菌存活率。
3.通过植物纤维层中木质纤维与竹纤维的宽度多在50-60um的区间，可以将一部分小颗粒物体进行剥离。
4.通过由细菌素制得的纤维素带状束宽为70-80nm，其直接远远小于玻璃纤维、化工纤维和植物纤维，具有高透气性，可以将其他过滤材料很难过滤的干净的物质进行过滤，大幅降低导入室内的PM2.5含量。
