具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
本实用新型实施例提供的天然气净化用脱酸橇，包括：底橇9，设置于底橇9上的聚结式过滤器5、板翅式换热器6、净化气分离器11、活性炭过滤器7、机械过滤器8、板式换热器12、贫胺液泵13、贫胺液空冷器10、酸气空冷器2、酸气分离器4和胺液储罐3。
具体的，聚结式过滤器5的原料气出口与板翅式换热器6的原料气进口连通，板翅式换热器6的原料气出口用于与吸收塔的原料气进口连通，板翅式换热器6的净化气进口用于与吸收塔的出口连通，板翅式换热器6的净化气出口与净化气分离器11的进口连通；胺液储罐3能够与贫胺液泵13连通，活性炭过滤器7、机械过滤器8沿胺液流向依次连通，板式换热器12的第一进口与机械过滤器8的出口连通，板式换热器12的第一出口用于与再生塔的胺液进口连通，板式换热器12的第二进口用于与再生塔的胺液出口连通，板式换热器12的第二出口与贫胺液泵13连通，贫胺液泵13与贫胺液空冷器10连通，贫胺液空冷器10用于与吸收塔的胺液进口连通，活性炭过滤器7的进口用于与吸收塔的胺液出口连通；酸气空冷器2的进口用于与再生塔的酸气出口连通，酸气空冷器2的出口与酸气分离器4连通，酸气分离器4的胺液出口与板式换热器12的第二出口连通。
在实际使用过程中，原料气经聚结式过滤器5过滤后进入板翅式换热器6，原料气被加热，加热后的原料气进入吸收塔，原料气中的酸气被吸收塔中的胺液吸收后形成净化气，净化气流入板翅式换热器6，净化气与原料气换热，净化气被降温，降温后的净化气流入净化气分离器11，然后流向下一处理设备；脱酸处理之前，将胺液储罐3打开，胺液流入贫胺液泵13，待胺液排出量满足生产需求时，关闭胺液储罐3，胺液经贫胺液泵13进入贫胺液空冷器10，胺液经过贫胺液空冷器10后进入吸收塔，在吸收塔内胺液吸收酸气后流出吸收塔并经活性炭过滤器7、机械过滤器8过滤后自第一进口进入板式换热器12，胺液经过板式换热器12后自第一出口流出并进入再生塔，胺液经过再生塔后自第二进口进入板式换热器12，贫富两种胺液进行换热，自第二进口进入的胺液自第二出口流出板式换热器12，自板式换热器12第二出口流出的贫胺液经贫胺液泵13后进入贫胺液空冷器10，按照上述流程循环；胺液在经过再生塔后，胺液中的酸气被脱离，再生塔内的酸气自酸气出口流出并进入酸气空冷器2，酸气经过酸气空冷器2后进入酸气分离器4，酸气和胺液分离，酸气排空或进一步处理，胺液经板式换热器12第二出口后管道流入胺液循环系统，重复利用。
本实用新型实施例提供的天然气净化用脱酸橇，通过将聚结式过滤器5、板翅式换热器6、净化气分离器11、活性炭过滤器7、机械过滤器8、板式换热器12、贫胺液泵13、贫胺液空冷器10、酸气空冷器2、酸气分离器4和胺液储罐3设置在底橇9上，则移动整个底橇9，即可实现对大部分脱酸处理设备的移动，移动前后，只需拆卸底橇9以及安装底橇9即可，与现有技术逐一移动脱酸处理设备相比，有效简化了脱酸处理设备的移动，从而提高了脱酸处理设备的移动效率。
可以理解的是，由于吸收塔和再生塔较大，只能单独设置，在移动过程中，还需要单独移动吸收塔和再生塔。
同时，本实用新型实施例提供的天然气净化用脱酸橇，移动底橇9，即可实现对大部分脱酸处理设备的移动，移动前后，只需拆卸底橇9以及安装底橇9即可，有效减小了移动脱酸处理设备所需的工作量，降低了移动成本。
为了提高底橇9的受力均匀性，优先选择胺液储罐3位于底橇9的中部，酸气空冷器2和贫胺液空冷器10位于底橇9的一端；板翅式换热器6、活性炭过滤器7、机械过滤器8和酸气分离器4位于胺液储罐3的一侧，聚结式过滤器5、净化气分离器11和贫胺液泵13位于胺液储罐3的另一侧。由于胺液储罐3的重量较大，所以选择胺液储罐3位于底橇9的中部，保证整个底橇9的重心居中；同时，将板翅式换热器6、活性炭过滤器7、机械过滤器8、酸气分离器4以及聚结式过滤器5、净化气分离器11和贫胺液泵13设置在胺液储罐3的两侧，方便了连接这些部件间的管路设置，也方便了该管路上阀门的操作和维修。
为了简化结构，减小占用的空间，优先选择酸气空气器2和贫胺液空冷器10为一体式结构，且酸气空气器2位于贫胺液空冷器10的顶部。进一步的，酸气空气器2和贫胺液空冷器10共用一个风机。
采用MDEA(甲基二乙醇胺)溶液在天然气脱酸过程中会产生泡沫，因此需要加入消泡剂消除泡沫。考虑到往脱酸系统里加注消泡剂的操作便利性，优先选择消泡剂管段1位于底橇9一端的边缘。
上述天然气净化用脱酸橇中，会用到多个阀门，为了便于操作和维修，优先选择天然气净化用脱酸橇的阀门距底橇9的橇面的距离为0-1.8m。
优选的，上述天然气净化用脱酸橇中，板翅式换热器6和酸气分离器4均采用支耳式支座，且支耳式支座下方铺设有管道。这样，可充分利用底橇9的空间。
在实际应用过程中，当贫胺液泵13出现损坏时，需要维修或者替换，这样会影响整个天然气净化用脱酸橇的脱酸效率，为了避免降低脱酸效率，优先选择贫胺液泵13的数目为两个，一个贫胺液泵13为使用泵，另一个贫胺液泵13为备用泵。当其中一个被损坏时，操作阀门使用另一个贫胺液泵13即可，无需拆卸并重新安装，避免了影响正常生产，从而提高了脱酸效率。
优选的，上述天然气净化用脱酸橇中，贫胺液泵13为柱塞泵。当然，也可选择其他结构的换热器进行换热，本实用新型实施例对此不做限定。
上述实施例提供的天然气净化用脱酸橇中，设备、管路及钢结构颜色根据行业规范和公司规定调配，例如石油化工行业标准(SH 3043)。具体的，不保温设备、仪表箱为灰色，钢结构蓝灰色，天然气管路为黄色，放空管路为大红色，需要保温的设备和管路均为底漆颜色，方便了找到相应部件，同时也使整个天然气净化用脱酸橇的色彩更加美观。
对所公开的实施例的上述说明，使本领域技术人员能够实现或使用本实用新型。对这些实施例的多种修改对本领域技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本实用新型的精神或范围的情况下，在其它实施例中实现。因此，本实用新型将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
