本公开涉及吸收塔技术领域，具体涉及一种用于气体捕集的吸收塔。
化学吸收法气体捕集系统包括吸收单元，贫富液热交换单元和解吸单元三个主要部分。其中，吸收单元主要是吸收塔，塔体内有吸收段和水洗段。例如二氧化碳吸收过程中，溶液从吸收塔的吸收段上部进入，自上向下流动。含二氧化碳气体从吸收塔塔底进入吸收塔内部，均匀上升到填料区。液体和气体二者对流接触发生反应，从而实现二氧化碳的吸收。
相关技术中，吸收塔采用堆叠式布置，保证气体在吸收塔中充分反应或者被充分吸收，但堆叠式布置会导致吸收塔的高度较高(高度会超过40米)，不利于有高度限制的场景中，例如建筑物或者船只上设置。

下面详细描述本公开的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
如图1所示，本公开实施例的用于气体捕集的吸收塔包括：吸收塔本体1、第一输送组件31和第二输送组件32。
吸收塔本体1内具有腔室，吸收塔本体1上设有进气口132、排气口111、进液口121和排液口，腔室包括在位于吸收塔本体1的高度方向(如图1中的上下方向)上的中间位置的反应室，进液口121和排气口111位于反应室上方，进气口132和排液口位于反应室下方。在一些具体实施例中，如图1所示，吸收塔本体1沿自上而下的方向依次设置有排气段11、反应段12和排液段13，排气口111开设在排气段11，以便用于排出反应后的烟气，排液口开设在排液段13，以便用于排出反应后的反应液体。
反应室包括在第一方向上间隔布置的第一反应室20、第二反应室211和第三反应室221，第一方向正(如图1中的左右方向)交于吸收塔本体1的高度方向，进气口132与第一反应室20、第二反应室211、第三反应室221连通以便烟气分别通入到第一反应室20、第二反应室211和第三反应室221，进液口121与第一反应室20连通以便反应液体通入到第一反应室20内，排气口111和排液口与第三反应室221连通。
第一输送组件31与第一反应室20的下部相连，且第一输送组件31与第二反应室211的上部相连，以用于将烟气和反应液体在第一反应室20内反应后的反应液体输送至第二反应室211，从而便于反应后的反应液体与通入第二反应室211内的烟气发生反应。
第二输送组件32与第二反应室211的下部相连，且第二输送组件32与第三反应室221的上部相连，以用于将第二反应室211内反应后的反应液体输送至第三反应室221，从而便于反应后的反应液体与通入第三反应室221内的烟气发生反应。
在一些具体实施例中，如图1所示，第一反应室20、第二反应室211和第三反应室221沿左右方向布置，从而可以避免吸收塔整体的高度过高，从而方便应用在船只、建筑等场景内。第一输送组件31连接在第一反应室20和第二反应室211之间，以便能够利用第一输送组件31将第一反应室20内与烟气发生反应后的反应液体抽出并通入第二反应室211内，使进入第二反应室211内的反应液体在第二反应室211内与通入第二反应室211
的烟气进行反应。同理，第二输送组件32将第二反应室211内反应后的反应液体通入第三反应室221，使进入第三反应室221内的反应液体在第三反应室221内与通入第三反应室221的烟气进行反应。
需要说明的是，以下均以捕集二氧化碳为例，则反应液体为能够吸收二氧化碳的液体，烟气为具有二氧化碳的气体，当烟气和反应液体通入第一反应室20后，烟气中的部分二氧化碳能够溶于反应液体并使反应液体的温度升高，再利用第一传输组件将第一反应室20内反应后的反应液体输送至第二反应室211，以便与第二反应室211内烟气中的二氧化碳发生反应，最后利用第二传输组件将第二反应室211内的反应液体输送至第三反应室221，以便与第三反应室221内烟气中的二氧化碳发生反应。
其中，发明人发现，在第一反应室20内的反应液体发生反应后，反应液体的温度会升高，在利用第一传输组件将第一反应室20内的反应液体与第二反应室211中的烟气发生反应室，会影响二氧化碳的吸收率。
由此，在一些实施例中，第一输送组件31还包括第一管道311、第一泵312和第一换热器313，第一管道311的第一端与第一反应室20相连，第一管道311的第二端与第二反应室211相连，第一泵312设在第一管道311上，第一换热器313设在第一泵312与第一管道311的第二端之间。
第二输送组件32还包括第二管道321、第二泵322和第二换热器323，第二管道321的第一端与第二反应室211相连，第二管道321的第二端与第三反应室221相连，第二泵322设在第二管道321上，第二换热器323设在第二泵322与第二管道321的第二端之间。
也就是说，第一换热器313和第二换热器323可以分别改变第一管道311和第二管道321内的反应液体的温度，从而提高反应液体对二氧化碳的吸收率，有利于对烟气中二氧化碳的捕集。
换言之，本公开实施例的用于气体捕集的吸收塔中的第一反应室20、第二反应室211和第三反应室221在第一方向上依次布置，避免堆叠设置导致的吸收塔整体高度过高，从而方便在船只上以及建筑内建造使用，应用范围广。
此外，还可以利用第一输送组件31和第二输送组件32在输送反应液体时，改变反应液体的温度，以使反应液体具有一定的二氧化碳吸收率，以更好的捕集烟气中二氧化碳。
因此，本公开实施例的用于气体捕集的吸收塔具有应用范围广、捕集效果好的优点。
当然，本公开实施例的用于气体捕集的吸收塔还能应用于捕集二氧化硫等其它气体。
在一些实施例中，本公开实施例的用于气体捕集的吸收塔还包括第一筒体21和第二筒体22，第一筒体21设在腔室内，第一筒体21的周壁和吸收塔本体1的周壁之间形成
第一反应室20，第二筒体22设在第一筒体21的空腔内，第二筒体22的周壁和第一筒体21的周壁之间形成第二反应室211，第二筒体22的空腔形成第三反应室221。
可以理解的是，如图2和图3所示，第二反应室211环绕第三反应室221设置，第一反应室20环绕第二反应室211设置，由此，能够更好的保证第一反应室20、第二反应室211和第三反应室221在使用过程中，反应室内的温度均匀，有效的防止在使用过程中受外部环形的影响，而导致反应室内的温度不均匀，影响反应效果。
在一些实施例中，第一筒体21、第二筒体22和吸收塔本体1在正交于吸收塔本体1的高度方向上的投影轮廓相似，第一筒体21、第二筒体22和吸收塔本体1在正交于吸收塔本体1的高度方向上的投影轮廓为圆形或正多边形。
可以理解的是，如图2和图3所示，在俯视视角下，第一筒体21、第二筒体22和吸收塔本体1的边缘轮廓可以为圆形或者正多边形。也就是说，本公开实施例的吸收塔可以根据使用场景的不同，设计为不同的外形，例如圆形或者长方形，有利于更好的适用在不同的环境。
在一些实施例中，第一反应室20在正交于吸收塔本体1的高度方向上的投影面积小于第二反应室211在正交于吸收塔本体1的高度方向上的投影面积，第二反应室211在正交于吸收塔本体1的高度方向上的投影面积小于第三反应室221在正交于吸收塔本体1的高度方向上的投影面积。
可以理解的是，当第一反应室20内的反应液体在与烟气反应后，通入第二反应室211继续与第二反应室211内的烟气继续反应，那么，在第二反应室211中的反应效果要弱于第一反应室20内的反应效果(即反应液体在第二反应室对二氧化碳的吸收效率相对于在第一反应室对二氧化碳的吸收效率有所降低)，在第三反应室221中的反应效果又弱于第二反应室211内的反应新效果，由此，可以将反应场所的空间增加，以提高反应时长。因此，设置第二反应室211的容积大于第一反应室20的容积，设置第三反应室221的容积大于第二反应室211的容积。
在一些实施例中，第一反应室20和第二反应室211的每一者与排气口111和排液口中的每一者连通。
可以理解的是，第一反应室20和排气口111连通且和排液口连通，第二反应室211和排气口111连通且和排液口连通。
也就是说，由于反应液体在第二反应室211和第三反应室221中的反应效率相较于在第一反应室20中的反应效率，因此，在持续进行捕集二氧化碳时，会导致第一反应室20、第二反应室211中的反应液体越来越多，由此，可以利用排液口将多余的反应液体排
出。同理，可以利用排气口111将第一反应室20和第二反应室211还有第三反应室221中的气体排出。
在一些实施例中，本公开实施例用于气体捕集的吸收塔还包括第一喷淋件41、第二喷淋件42和第三喷淋件43，第一喷淋件41设在第一反应室20内且与第一反应室20的顶壁相连，第一喷淋件41与进液口121连通。第二喷淋件42设在第二反应室211内且与第二反应室211的顶壁相连，第二喷淋件42与第一管道311的第二端连通。第三喷淋件43设在第三反应室221内且与第三反应室221的顶壁相连，第三喷淋件43与第二管道321的第二端连通。
在一些具体实施例中，如图1所示，第一喷淋件41设在第一反应室20的顶部，通过第一喷淋件41的反应液体能够与烟气更充分的反应，提高捕集效果。同理，第二喷淋件42和第三喷淋件43分别能够提高第二反应室211和第三反应室221内的捕集效率。
在一些实施例中，第一喷淋件41、第二喷淋件42和第一喷淋件41均为多个，多个第一喷淋件41沿第一反应室20的周向间隔布置，多个第二喷淋件42沿第二反应室211的周向间隔布置，多个第三喷淋件43沿第三反应室221的周向间隔布置。
在一些实施例中，本公开实施例的用于气体捕集的吸收塔还包括第一出液口、第二出液口和第三出液口，第一出液口设在第一反应室20的底壁，第一出液口用于连通第一反应室20和排液段13。第二出液口设在第二反应室211的底壁，第二出液口用于连通第二反应室211和排液段13。第三出液口设在第三反应室221的底壁，第三出液口用于连通第三反应室221和排液段13。
可以理解的是，第一反应室20的底壁设有第一出液口，第一出液口与排液口连通，以便第一反应室20内多余的反应液体能够依次通过第一出液口和排液口排出。同理，第二反应室211内多余的反应液体能够依次通过第二出液口和排液口排出，第三反应室221内的反应液体能够依次通过第三出液口和排液口排出。
在一些实施例中，第一出液口、第二出液口和第三出液口均为多个，多个第一出液口沿第一反应室20的周向间隔布置，多个第二出液口沿第二反应室211的周向间隔布置，多个第三出液口沿第三反应室221的周向间隔布置。
在一些实施例中，本公开实施例的用于气体捕集的吸收塔还包括第一通气管51、第二通气管52和第三通气管53，第一通气管51的第一端设在第一反应室20的底壁上且与进气口132连通，第一通气管51的第二端沿远离第一反应室20的底壁的方向延伸。第二通气管52的第一端设在第二反应室211的底壁上且与进气口132连通，第二通气管52的第二端沿远离第二反应室211的底壁的方向延伸。第三通气管53的第一端设在第三反应室
221的底壁上且与进气口132连通，第三通气管53的第二端沿远离第三反应室221的底壁的方向延伸。
在一些具体实施例中，如图1所示，第一通气管51的下端与第一反应室20的底壁相连且与进气口132连通，第一通气管51的上端位于第一反应室20内，则第一通气管51的上端高于第一反应室20的底壁，以避免利用第一出液口排液时，第一反应室20内的烟气从第一出液口泄漏出去。同理，第二通气管52能够避免利用第二出液口排液时，第二反应室211内的烟气从第二出液口泄漏出去，第三通气管53能够避免利用第三出液口排液时，第三反应室221内的烟气从第三出液口泄漏出去。
可以理解的是，第一通气管51的上端端口与第一反应室20的底壁之间的第一反应室20形成第一集液器，以便能够收集第一反应室20内的液体，同理，第二通气管52的上端端口与第二反应室21的底壁之间的第二反应室211形成第二集液器，以便收集第二反应室211内的液体，第三通气管53的上端端口与第三反应室221的底壁之间的第二反应室20形成第二集液器，以便收集第三反应室221内的液体。
在一些实施例中，第一通气管51、第二通气管52和第三通气管53均多个，多个第一通气管51沿第一反应室20的周向间隔布置，多个第二通气管52沿第二反应室211的周向间隔布置，多个第三通气管53沿第三反应室221的周向间隔布置。
