Description

多层复合过滤袋
技术领域
本发明涉及空气过滤领域，特别涉及一种多层复合过滤袋。
背景技术
过滤袋为袋状的除尘过滤器，空气从袋体的开口处进入，经过过滤袋，对空气中的有害物质和灰尘进行过滤，将有害物质和灰尘截留在袋体上；
现有的过滤袋一般使用支撑物将过滤袋撑开，但是对于安装在空调箱上的过滤袋，其存在支撑物质量较重的问题。
发明内容
本发明解决的技术问题是提供一种不需要使用支撑物支撑过滤袋，过滤袋可以根据风的大小而张开或闭合，使得与空气充分接触、提高过滤效率的多层复合过滤袋。
本发明解决其技术问题所采用的技术方案是：多层复合过滤袋，包括化学滤网层和玻纤层，所述化学滤网层和玻纤层对应的三个边缝合在一起，使之成为一个敞口的袋体，所述袋体的轴向上缝合有多条拉线，所述拉线穿过化学滤网层和玻纤层，所述拉线为松弛状，使得袋体可以根据风的大小而张开或闭合，使得袋体能够与空气充分接触，提高空气的过滤效率，所述化学滤网层用于去除空气中的有害物质，如二氧化硫、酸性物质或碱性物质，所述玻纤层用于去除空气中的灰尘等。
进一步的是：所述化学滤网层和玻纤层对称设置有两层，使得空气可以从袋体的上侧或下侧通过，无论空气是从袋体的上侧还是从袋体的下侧通过，均通过化学滤网层和玻纤层，进行过滤。
进一步的是：所述玻纤层设置在化学滤网层的内侧，先去除空气中的灰尘等，然后再去除空气中的有害物质。
进一步的是：所述多条拉线阵列设置，使得袋体在有风进入后能够有规律的张开或闭合，使得空气与袋体充分接触，不至于袋体一半张开一半闭合。
进一步的是：所述袋体的最外层位于拉线处设置有覆盖层，所述覆盖层用于封住拉线穿过的孔，防止化学滤网层漏碳。
本发明的有益效果是：本发明中的拉线为松弛状，使得袋体可以根据风的大小而张开或闭合，使得袋体能够与空气充分接触，提高空气的过滤效率，同时节省了支撑物，所述化学滤网层能够去除空气中的有害物质，所述玻纤层能够去除空气中的灰尘等。
附图说明
图1为多层复合过滤袋张开状态时的结构示意图；
图2为多层复合过滤袋的截面图；
图中标记为：1、化学滤网层；2、玻纤层；3、拉线；4、覆盖层。
具体实施方式
下面结合附图和具体实施方式对本发明进一步说明。
如图1、图2所示的多层复合过滤袋，包括化学滤网层1和玻纤层2，所述化学滤网层1和玻纤层2对应的三个边缝合在一起，使之成为一个敞口的袋体，所述袋体的轴向上缝合有多条拉线3，所述拉线3穿过化学滤网层1和玻纤层2，所述拉线3为松弛状，使得袋体可以根据风的大小而张开或闭合，使得袋体能够与空气充分接触，提高空气的过滤效率，所述化学滤网层1用于去除空气中的有害物质，如二氧化硫、酸性物质或碱性物质，所述玻纤层2用于去除空气中的灰尘等。
在上述基础上，所述化学滤网层1和玻纤层2对称设置有两层，使得空气可以从袋体的上侧或下侧通过，无论空气是从袋体的上侧还是从袋体的下侧通过，均通过化学滤网层1和玻纤层2，进行过滤。
在上述基础上，所述玻纤层2设置在化学滤网层1的内侧，先去除空气中的灰尘等，然后再去除空气中的有害物质。
在上述基础上，所述多条拉线3阵列设置，使得袋体在有风进入后能够有规律的张开或闭合，使得空气与袋体充分接触，不至于袋体一半张开一半闭合。
在上述基础上，所述袋体的最外层位于拉线3处设置有覆盖层4，所述覆盖层4用于封住拉线3穿过的孔，防止化学滤网层1漏碳。
以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
