具体实施方式
下面结合附图及具体实施例对本发明作进一步的详细说明。
参阅附图1-3，本发明所述的一种废气喷淋塔,包括塔体1、排废气管3、出废气管4、过滤层2、喷淋液箱5、连接管路6、电机7、伸缩气缸8、流通管路9、压力泵10、喷淋管11、三通接头12、第一喷头13、流动管路14、第二喷头15和废液收集装置；所述塔体1的上端设有排废气管3，排废气管3上设有与其相通的横向设置的出废气管4，出废气,4的两端设有出气口；所述塔体1的下部设有废气进口16；所述塔体1的中间设有过滤层2，将塔体1分为第一喷淋室和第二喷淋室；所述塔体1的下端固设有喷淋液箱5；所述喷淋液箱5两端通过连接管路6与电机7相连，连接管路6为软管，且电机7的一端与伸缩气缸8相连；所述连接管路6通过电机7内的流通管路与9电机7的转轴相联通，且电机7的转轴呈空心状，连接管路6上设有压力泵10；所述电机7的转轴与位于第一喷淋室的喷淋管11相连；所述喷淋管11上设有三通接头12；所述三通接头12上设有两个可拆卸的第一喷头13；所述连接管路6上设有流动管路14；所述流动管路14插入到第二喷淋室内与第二喷头15相联通；所述塔体1底部还设有废液收集机构，用于对废液进行收集。
具体使用时，首先废气通过废气进口引入到塔体1内，压力泵10将喷淋液箱5内的氧化钠吸抽到第一喷头13和第二喷头15内，从而通过第一喷头13 和第二喷头15将氢氧化钠喷射到第一喷淋室和第二喷淋室中，废气与氢氧化钠吸收液进行气液两相充分接触吸收中和反应，最后通过出废气管4排出，其中过滤层2是对第二喷淋室排出的废气进行再次净化；第一喷淋室中的第一喷头13喷淋的效果较好，这时因为：其具有多个第一喷头13，同时可以通过电机7驱动第一喷头13进行转动，使得第一喷头13可以多方位均匀的对第一喷淋室进行喷射，并且第一喷头13还能通过伸缩气缸8对第一喷头13的横向位置进行调整，确保第一喷头13喷射时的喷射均匀，保证氢氧化钠能和废气完全反应。
优选的，所述电机7的转轴与喷淋管11之间为螺纹连接，这样便于拆洗和维护。
优选的，所述喷淋管11内设有滤网110，这样能避免一些大颗粒物质喷入到塔体的第一喷淋室和第二喷淋室内。
优选的，本废气喷淋塔还可以对废液进行收集，废液收集装置包括废液管路51、堵塞杆52、升降气缸53、废液传输管54、废液箱55和增压泵56；所述废液管路51与塔体1底部的出口相联通；所述废液管路51内设有堵塞杆52；所述堵塞杆52与升降气缸53的活塞杆相连；所述废液管路51的出液口510与废液传输管54相联通，且堵塞杆52将出液口510密封住；所述废液传输管54与废液箱55相联通；所述废液传输管54内还设有增压泵56，当塔体底部的废液较多时，此时开启升降气缸，使得升降气缸的伸缩杆带动堵塞杆往下移动，从而将出液口露出来，这样塔体底部的废液就从出液口流入废液传输管内，并通过废液传输管进入到废液箱内，加入增压泵是为了提高抽取的动力。
进一步的，所述排废气管3内还设有活性炭过滤器30；所述出废气管4内壁上位于活性炭过滤器30的上方设有磁性吸板31；活性炭过滤器30进一步 的对废气进行过滤，而磁性吸板31能对一些铁屑杂质等进行吸收。
本发明的废气喷淋塔，结构简单，操作方便，能较好的对废气进行处理，其中的第一喷头能多方位的对第一喷淋室内进行喷射，保证废气和氢氧化钠充分反应，便于后续的排出，同时能对废液进行自动的收集，符合实际的生产加工需求。
以上仅是本发明的具体应用范例，对本发明的保护范围不构成任何限制。凡采用等同变换或者等效替换而形成的技术方案，均落在本发明权利保护范围之内。
