具体实施方式
尽管本发明容许各种修改和可替换的形式，但是它的具体的实施例通过例子的方式在附图中示出，并且将详细地在本文中描述。然而，应该理解，随附的附图和详细的描述不是为了将本发明限制到公开的具体形式，而是相反，是为了覆盖落入由随附的权利要求限定的本发明的精神和范围中的所有的修改、等同形式和替换形式。附图是为了示意，因而不是按比例地绘制的。
在本说明书中使用了“第一”、“第二”等术语，并不是为了排序或者表示重要性或主次关系，而是用于区分不同的部件。本说明书中“顶侧”和“底侧”是相对于一般情况下，物体正立的上侧和下侧的方位。
下面根据附图说明根据本发明的多个实施例。
参见图1和图2，本发明的实施例提供一种气体净化装置，包括：
第一净化剂容器4，包括用于净化气体的净化剂，并且配置成能够在气体通过第一净化剂容器的过程中净化气体；
第二净化剂容器5，包括用于净化气体的净化剂，并且配置成能够在 气体通过第二净化剂容器的过程中净化气体；以及
连通第一净化剂容器4和第二净化剂容器5的阀3，所述阀3配置成能够在第一状态下允许气体从第二净化剂容器5流向第一净化剂容器4，在第二状态下允许气体从第一净化剂容器4流向第二净化剂容器5。
根据本实施例，第一净化剂容器4和第二净化剂容器5通过阀3连接起来，从而可以实现第一净化剂容器4净化气体，并且之后使用过的气体可以再次流经第二净化剂容器5，实现气体净化第二净化剂容器5，反之亦然，即第二净化剂容器5净化气体，之后使用过的气体可以再次流经第一净化剂容器4，实现气体净化第一净化剂容器4。使用这样的配置方式，可以不用如现有技术那样需要手动更换净化剂，只需要使用阀3改变气体流过的方向即可以在净化气体的同时，利用使用过的气体净化第一净化剂容器4和第二净化剂容器5中没有用于净化气体的一个，因而大大改善了实际使用的便利性。
根据本发明的实施例，气体在流经第一净化剂容器4或第二净化剂容器5之后被净化或吸附，经过净化或吸附后的气体可以作为例如载气等使用，例如净化或吸附后的气体可以通入分析器件。
例如，在本公开的一个实施例中，气体净化装置与分析器件连接，气体净化装置与分析器件可以一起构成一个分析设备。在内本公开的另一实施例中，气体净化装置包括分析器件接口，配置在第一净化剂容器4和第二净化剂容器5之间，适于接入分析器件，并且在未接入分析器件的时候保持气路的连通。
当分析器件配置在第一净化剂容器4和第二净化剂容器5之间，气体净化装置被配置成使得：在阀3处于第一状态下气体从第二净化剂容器5流出，净化后的气体经过所述阀3，进入所述分析器件，从所述分析器件排出的气体朝向第一净化剂容器4流动；并且，在阀3处于第二状态下气体从第一净化剂容器4流出，净化后的气体经过所述阀3，进入所述分析器件，从所述分析器件排出的气体朝向第二净化剂容器5流动。分析器件可以是例如离子迁移管1，或可以是光谱分析仪，或其他对气体进行分析的装置。
在本实施例中，当阀3处于第一状态下，气体从第二净化剂容器5流出后，被净化的气体经过所述阀3进入例如分析器件中，从分析器件排出的气体可以进入第一净化剂容器4再次被使用，例如净化第一净化剂容器4；反过来，阀3处于第二状态，气体从第一净化剂容器4流出后，被净化的气体经过所述阀3进入分析器件中，从分析器件排出的气体可以进入第二净化剂容器5再次被使用，例如净化第二净化剂容器5。应该知道，本公开的实施例的气体净化装置可以不加入分析器件，这完全不影响气体净化装置的操作；实际上，分析器件可以在使用时方便地接入到其他净化装置的气体流路中，本公开为了描述方便，以分析器件接入净化装置的流路中进行描述，以便本领域技术人员应用本公开的气体净化装置。显然，基于本公开的教导，本领域技术人员可以将任何分析器件接入到本公开的气体净化装置中去。
我们知道，净化剂在使用一段时间后需要清洁或再生。根据本实施例，例如先使用第一净化剂容器4净化气体，由于吸附了气体中的物质，使用一段时间后，第一净化剂容器4需要清洁或再生，此时，调节阀3的状态，使用第二净化剂容器5净化气体，而从分析器件中使用后的气体被排出，(或者来自第二净化剂容器5的净化气体直接)通向第一净化剂容器4，气体流过第一净化剂容器4，净化了第一净化剂18，反之亦然。
在本公开的一个实施例中，气体净化装置还包括加热装置，即第一净化剂容器4包括第一加热器17，第一加热器17配置成加热所述第一净化剂容器4中的第一净化剂18；第二净化剂容器5包括第二加热器27，第二加热器27配置成加热所述第二净化剂容器5中的第二净化剂28。
通过加热净化剂可以让净化剂中的水汽和挥发性有机物(volatile organic compounds，VOCs)等挥发出来，从而实现再生，而通过将气体通过净化剂，可以将这些水汽和杂质吹扫出去，从而能够提高清洁净化剂的效率。另外，升高净化剂的温度有利于提高净化剂再生的效率，改善清洁净化剂的效果。根据本实施例，气体净化装置设置第一加热器17以加热所述第一净化剂容器4中的第一净化剂18，设置第二加热器27加热所述第二净化剂容器5中的第二净化剂28，从使得在净化气体的同时，有效 且快速地清洁净化剂。
在一个实施例中，第一加热器17可以是电热丝，其穿过第一净化剂18，以蜿蜒的方式布置在第一净化剂18内，以便均匀加热第一净化剂18；第二加热器27可以是电热丝，其穿过第二净化剂28，以蜿蜒的方式布置在第二净化剂28内，以便均匀加热第二净化剂28。
在另一实施例中，第一加热器17可以是多个电热块，多个电热块分散地且均匀地分布在第一净化剂18内，以便均匀地加热第一净化剂18；第二加热器27可以是多个电热块，多个电热块分散地且均匀地分布在第二净化剂28内，以便均匀地加热第二净化剂28。
具体地，所述气体净化装置配置成在阀3处于第一状态下，气体从第二净化剂容器第二端52进入第二净化剂容器5，从第二净化剂容器第一端51流出，进入所述阀3的第一端口A，从所述阀3的第二端口R排出，进入所述分析器件(例如离子迁移管1)，随后气体从所述阀3的第三端口P进入所述阀3，从所述阀3的第四端口B排出，朝向第一净化剂容器4，从第一净化剂容器第一端41进入第一净化剂容器4，从第一净化剂容器第二端42排出，同时第一加热器17加热第一净化剂18。所述气体净化装置配置成在阀3处于第二状态下，气体从第一净化剂容器第二端42进入第一净化剂容器4，从第一净化剂容器第一端41离开第一净化剂容器4，进入所述阀3的第四端口B，从所述阀3的第二端口R排出，进入所述分析器件，随后气体从所述阀3的第三端口P进入所述阀3，从所述阀3的第一端口A排出，朝向第二净化剂容器5，从第二净化剂容器第一端51进入第一净化剂容器4，从第二净化剂容器第二端52排出，同时第二加热器27加热第二净化剂28。
在一个实施例中，阀3可以是四通电磁阀3，四通电磁阀3处于第一状态，即为四通电磁阀3处于断电状态；四通电磁阀3处于第二状态即为四通电磁阀3处于通电状态。如图1所示，当四通电磁阀3断电时，气体可以从四通电磁阀3的第一端口A流向第二端口R，从所述阀3的第三端P流向第四端口B；当四通电磁阀3处于第二状态，即通电状态，气体可以从四通电磁阀3第四端B流向第二端口R，从四通电磁阀3的第三端口 P流向第一端口A。设置四通电磁阀3是有利的，可以获得简单结构的气体净化装置。
例如，在本发明的另一实施例中，阀3可以是两位三通电磁阀3，然而，需要四个两位三通电磁阀3，本领域技术人员可以根据本发明的上述要求设置气体流路，但是气体净化装置的结构比本公开的上述实施例复杂。
在本公开的一个实施例中，气体净化装置还可以包括泵2，泵2可以连接在第一净化剂容器4和第二净化剂容器5之间，在气体流动方向上位于所述分析器件的下游，用于在第一状态下或第二状态下驱动气体流动。设置泵2是有利的，在泵2的作用下，气体在气体净化装置里流动，达到净化气体和气体净化装置身清洁/再生的过程；泵2设置在气体流路中的分析器件的下游是有利的，避免泵2污染气体；在本实施例中，泵2的配置方式使得一个泵2即可以实现促进气体的流动。
在本发明的其他实施例中，可以在第一净化剂容器的第一净化剂容器第二端42设置泵，在第二净化剂容器的第二净化剂容器第二端52设置另一泵，设置两个泵也可以实现气体在气体净化装置中的流动。然而，本公开设置一个泵位于第一净化剂容器和第二净化剂容器之间并且位于分析器件的下游是有利的，使得整个装置的结构更加简单，成本低。
在本公开的气体净化装置的一个实施例中，第一净化剂容器4还包括第一壳体110，第一净化剂18容纳在第一壳体110内；第二净化剂容器5还包括第二壳体210，第二净化剂28容纳在第二壳体210内。然而，应该知道，气体净化装置可以包括一个壳体，其中第一净化剂容器4位于该壳体的第一部分，第二净化剂容器5位于壳体的第二部分。
第一壳体110和第二壳体210可以是绝缘材料，优选是绝热材料形成的。

在本公开的一个实施例中，第一壳体110包括第一保温层16，配置成包围第一净化剂容器4的全部或部分以隔离第一净化剂18与外界环境之间的热量交换(即完全隔绝或大量减少第一净化剂18与第一保温层16外部的环境之间的热交换，基本上只有第一加热器17伸入到第一保温层16内的部分能够加热第一净化剂18)；和第二壳体210包括第二保温层26，配置成包围第二净化剂容器5的全部或部分以隔离第二净化剂28与外界环境之间的热量交换。
设置第一保温层16和第二保温层26是有利的，可以提高加热器加热的效率，使得加热升温速度提高。
在本公开的一个实施例中，气体净化装置还包括第一温度传感器19，配置成测量第一净化剂18的温度以便与第一加热器17一起控制第一净化剂18的温度；和，第二温度传感器29，配置成测量第二净化剂28的温度以便与第二加热器27一起控制第二净化剂28的温度。设置温度传感器是有利的，第一加热器17和第一温度传感器19配合可以将第一净化剂18的温度控制在想要的温度下，在气体通过第一净化剂18的时候更加有效地净化第一净化剂18，尽快实现第一净化剂18的再生，并且有利于延长净化剂的使用寿命。
在本公开的一个实施例中，气体净化装置还包括第一湿度传感器，配置成测量第一净化剂18的湿度；和，第二湿度传感器，配置成测量第二净化剂28的湿度。设置第一湿度传感器是有利的，可以监控第一净化剂18的湿度，以便能够及时对第一净化剂18进行清洁和处理，及时清洁第一净化剂18有利于延长第一净化剂18的使用寿命。类似地，第二湿度传感器有利于监控第二净化剂28的湿度，有利于及时清洁第二净化剂28，从而延长第二净化剂28的使用寿命。
在本发明的另一实施例中，第一温度传感器19和第一湿度传感器是一体的，例如用图中的19指示，第二温度传感器29和第二湿度传感器是一体的，例如用图中的29指示。
本发明的另一方面还提供一种离子迁移谱仪，包括上述的气体净化装置。在本实施例中，离子迁移谱仪连接在第一净化剂容器4和第二净化剂 容器5之间，使得经过第一净化器容器和第二净化剂容器5中的一个净化的气体进入离子迁移谱仪实施检测，从离子迁移谱仪排出的气体进入第一净化器容器和第二净化剂容器5中的另一个。
下面参照图1和图2描述本发明的气体净化装置和离子迁移管1的组合结构。
图1为第一净化剂容器4处于加热再生状态，第二净化剂容器5处于吸附状态时，两位四通电磁阀3处于非通电状态，第一净化剂容器4的第一加热器17处于通电加热状态。气路流向为：空气经过第二净化剂容器5的第二净化剂28，第二净化剂28吸附空气中的水汽和杂质，空气变洁净，洁净的空气从两位四通电电磁阀3的第一端口A流向第二端口R，作为离子迁移管1的迁移气和载气进入离子迁移管1，最后从离子迁移管1的排气管排出，流向泵2的吸气口，从泵2的排气口流出，通过两位四通电电磁阀3从第三端口P流向第四端口B，最后经过第一净化剂容器4的第一净化剂18，用于吹扫正在加热再生的第一净化剂18，带出第一净化剂18内的水，杂质污染等，最后流向空气。
图2为第一净化剂容器4处于吸附状态，第二净化剂容器5处于加热再生状态时，两位四通电磁阀3处于通电状态，第二净化剂容器5的第二加热器27处于通电加热状态。气路流向为：空气经过第一净化剂容器4的第一净化剂18，第一净化剂18吸附空气中的水汽和杂质，空气变洁净，净化的空气从两位四通电磁阀的第四端口B流向第二端口R，作为离子迁移管1的迁移气和载气进入离子迁移管1，最后从离子迁移管1的排气管排出，流向泵2的吸气口，从泵2的排气口流出，通过两位四通电磁阀3，从第三端口P流向第一端口A，最后经过第二净化剂容器5的第二净化剂28，用于吹扫正在加热再生的第二净化剂28，带出第二净化剂的水分子和其他杂质气体，最后流向空气。
由此，根据本发明的气体净化装置可以实现空气/气体净化和第一净化剂或第二净化剂的自身的净化和再生过程，使得可以在不需要停工、不需要手动拆卸净化剂容器更换净化剂的情况下同时实现空气的净化和净化剂的再生，减少净化剂的使用量，简化操作；由于可以及时清洁净化剂， 方便了净化操作，因而可以延长气体净化装置的寿命，减少停工时间；并且，值得提出的是，在净化空气的同时，洁净的空气可以得以利用，实现环境友好。
