Description

一种气体净化装置及其气体净化方法 技术领域
本发明涉及净化装置与净化方法，特别涉及一种气体净化装置及其气体净化方法。
背景技术
近年来，气体绝缘开关设备在我国得到了迅速的推广与应用，特别是随着我国城市电网建设和改造、轨道交通以及大型工矿企业等对开关设备提出了小型化、智能化、免维护、全工况等新的更高要求，高性能、高品质的充气柜在国内的需求越来越强烈。
在上述气体绝缘开关中，六氟化硫气体、氮气或者混合气体常被用作开关设备的绝缘介质。以六氟化硫气体为例，虽然其具有良好的电气绝缘性能和优异的灭弧性能，但是，如果不按正确的方法对其进行回收、再生处理，将对大气形成污染。
造成六氟化硫气体水分和有毒有害气体等杂质超标的原因来自于以下五个方面：一是六氟化硫新气中所含杂质；二是电气设备充气时带入杂质；三是六氟化硫气体在电弧作用下分解产生杂质；四是气体回收处理时带入的杂质；五是运行中大气水分渗入设备。
对于上述六氟化硫气体中的水分和分解物的处理通常是先停电，再通过专门的净化设备进行处理。然而，在经济飞速发展的今天，停电检修对社会经济的影响极大，严重影响了人们的日常生活和经济生产。
发明内容
为了解决现有气体绝缘开关中六氟化硫气体净化处理的技术问题，本发明提出了一种气体净化装置，包括用于连接气室的通气口，所述通气口设置有自封阀；还包括通气主管路、吸气模块、净化模块和呼气模块；所述通气口设置于该通气主管路的首端，在该通气主管路的末端分别连接吸气模块的首端和呼气模块的末端，吸气模块的末端与净化模块的首端相连接，净化模块的末端与呼气模块的首端相连接。
本发明还提出了一种净化气体的方法，利用气体净化装置进行，所述的气体净化装置包括用于连接气室的通气口，所述通气口设置有自封阀；还包括通气主管路、吸气模块、净化模块和呼气模块；所述通气口设置于该通气主管路的首端，在该通气主管路的末端分别连接吸气模块的首端和呼气模块的末端，吸气模块的末端与净化模块的首端相连接，净化模块的末端与呼气模块的首端相连接；所述的净化气体的方法包括如下步骤：
步骤A，将所述气体净化装置的通气口与气室相连接，开启自封阀；
步骤S2，吸气步骤：吸气模块从气室吸入待净化的气体；
步骤S3，判断步骤：判断待净化的气体是否已经达标；如果待净化的气体已经达标，执行步骤S6；如果待净化的气体尚未达标，执行步骤S4；
步骤S4，净化步骤：净化模块净化从气室吸入的待净化的气体；
步骤S5，呼气步骤：呼气模块将净化后的气体灌入气室，然后执行步骤S2；
步骤S6，结束。
本发明的气体净化装置及其气体净化方法，每个净化周期内从气室吸入的待净化的气体的量相对于气室内的气体总量而言非常小，因此不会影响到气体绝缘开关的正常工作。此时，可以在不停电的情况下完成对气体绝缘开关中的气体的净化工作。也就是说，本发明所述的气体净化装置的每个净化周期吸入气体的量虽然会使气体绝缘开关的气压在一个周期内有所下降，但这种气压的波动是在行业标准所允许的范围之内，不会影响开关的正常运行；从而确保了在不影响用户正常用电的情况下，通过一个通气口对高压开关设备的绝缘气体气室内的气体进行净化，达到了高压开关绝缘气体净化的目的，减少了有毒有害气体的排放，保护了生态环境，具有巨大的社会效益和经济效益。

  80. 如权利要求79所述的气体净化方法，其特征在于，所述气体净化装置的气体净化器与第三气阀之间还设置有第二气体成分检测传感器；所述的气体净化方法在步骤S4和步骤S5之间还包括步骤B：第二气体成分检测传感器检测净化后气体的气体成分；比较第二气体成分检测传感器的检测结果与第一气体成分检测传感器的检测结果，从而监测气体净化器的气体净化能力。
  81. 如权利要求80所述的气体净化方法，其特征在于，所述气体净化装置还包括抽真空管路；所述抽真空管路上顺序设置有第四气阀和抽真空泵，在所述抽真空泵后端设置有排气口； 第四气阀的后端与抽真空泵的前端相连接，第四气阀的前端与通气主管路、吸气模块、净化模块或呼气模块连通；所述的气体净化方法在步骤A之前还包括步骤S1：抽真空的步骤。
  82. 如权利要求81所述的气体净化方法，其特征在于，所述的步骤S1具体包括：关闭自封阀，开启除自封阀外的所有气阀，然后开启抽真空泵对气体净化装置进行抽真空操作至真空度为预定值。
  83. 如权利要求80所述的气体净化方法，其特征在于，所述气体净化装置还包括抽真空管路；所述抽真空管路上顺序设置有第四气阀和抽真空泵，在所述抽真空泵后端设置有排气口；第四气阀的后端与抽真空泵的前端相连接，第四气阀的前端与通气主管路、吸气模块、净化模块或呼气模块连通；所述的气体净化方法在步骤A与步骤S2之间还包括步骤S1：抽真空的步骤。
  84. 如权利要求65所述的气体净化方法，其特征在于，关闭第一气阀，开启除第一气阀外的所有气阀，然后开启抽真空泵对气体净化装置进行抽真空操作至真空度为预定值。
