Description

一种玻璃纤维石墨烯复合材料制成的空气过滤器
技术领域
本发明涉及空气净化领域，具体涉及一种玻璃纤维石墨烯复合材料制成的空气过滤器。
背景技术
现有的空气过滤器是通过多孔过滤材料的作用从气固两相流中捕集粉尘，从而使气体得以净化的设备。它把含尘量低的空气净化处理后送入室内，以保证洁净房间的工艺要求和一般空调房间内的空气洁净度。现有的空气过滤器一般都是将玻璃纤维或者是涤纶纤维作为过滤材料。玻璃纤维滤材具有耐温性好、伸长率低、强度高、耐腐蚀性好等特点, 同时因纤维表面光滑、直径细、过滤阻力小, 因而过滤效率高。但玻璃纤维耐折性和耐磨性差, 在使用过程中因频繁清灰而容易磨损、折断, 影响使用寿命。涤纶具有耐折、耐磨性好的优点, 但有强度低、伸长率大、不耐高温等缺点。
发明内容
为了克服上述存在的问题，本发明的目的是提供一种玻璃纤维石墨烯复合材料制成的空气过滤器。
本发明解决其技术问题所采用的技术方案是：
一种玻璃纤维石墨烯复合材料制成的空气过滤器，包括壳体、设置在壳体内的风道、设置在风道内的风机和滤芯盒，所述滤芯盒包括有由玻璃纤维构成的过滤网格，所述过滤网格外设置有石墨烯膜层。
作为上述技术方案的进一步改进，所述石墨烯膜层直接在过滤网格表面成型。
作为上述技术方案的进一步改进，所述石墨烯膜层设置在过滤网格的进风端和出风端。
作为上述技术方案的进一步改进，所述石墨烯膜层组成中空立方体，所述过滤网格设置在石墨烯膜层组成的中空立方体内。
作为上述技术方案的进一步改进，所述过滤网格的玻璃纤维中掺杂有石墨烯。将石墨烯掺杂在玻璃纤维中，可以增强玻璃纤维的柔韧性和耐磨性，加强其致密度，提高过滤器的使用效果，延长它的使用寿命。
本发明的有益效果是：
由于本发明的空气过滤器采用了玻璃纤维和石墨烯制作滤芯盒，克服了玻璃纤维耐折性和耐磨性差的缺点,又充分发挥了玻璃纤维过滤性能优良的特点，产品在过滤和净化空气的同时也具有了石墨烯的抑菌特点，可以抑制和杀灭过滤器聚集的病原微生物，且由于石墨烯膜层为外层，石墨烯比一般过滤材料的热耐受性更好，工作温度更高，可以扩大过滤器的使用场景，使过滤器能够在高温环境下也能正常工作。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的结构示意图。
具体实施方式
本发明提供了一种玻璃纤维石墨烯复合材料制成的空气过滤器，包括壳体、设置在壳体内的风道、设置在风道内的风机和滤芯盒，参照图1，所述滤芯盒1包括有由玻璃纤维构成的过滤网格2，所述过滤网格2外设置有石墨烯膜层3。在本实施例中，所述石墨烯膜层3设置在过滤网格2的进风端和出风端。此外，所述石墨烯膜层3还可组成中空立方体，过滤网格2设置在石墨烯膜层3组成的中空立方体内。
进一步的，所述石墨烯膜层3还可以直接在过滤网格2表面成型，或在过滤网格2的玻璃纤维中掺杂石墨烯。将石墨烯掺杂在玻璃纤维中或直接在玻璃纤维制成的过滤网格2表面成型，可以增强玻璃纤维的柔韧性和耐磨性，加强其致密度，提高过滤器的使用效果，延长它的使用寿命。
由于本发明的空气过滤器采用了玻璃纤维和石墨烯制作滤芯盒，克服了玻璃纤维耐折性和耐磨性差的缺点,又充分发挥了玻璃纤维过滤性能优良的特点，产品在过滤和净化空气的同时也具有了石墨烯的抑菌特点，可以抑制和杀灭过滤器聚集的病原微生物，且由于石墨烯膜层3为外层，石墨烯比一般过滤材料的热耐受性更好，工作温度更高，可以扩大过滤器的使用场景，使过滤器能够在高温环境下也能正常工作。
以上具体结构和尺寸数据是对本发明的较佳实施例进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可做出种种的等同变形或替换，这些等同的变形或替换均包含在本申请权利要求所限定的范围内。
