Description
本实用新型涉及一种有机硅废气处理装置。
生产有机硅助剂所产生的废气是含有硅氧烷的VOC(挥发性有机化合物)废气，蓄热式氧化燃烧器处理这种特殊废气时，硅在高温中氧化为SiO
2而呈玻璃态状，它可以使陶瓷矩鞍环结块成团和堵塞蜂窝填料的小孔，从而引起床层压降升高，甚至造成装置不能运转而停工。现在许多环保公司已研究出各类防止、清除SiO
2的方法，如将废气先集中燃烧，采用移动床等。但这些方法成本高、后期维护困难。
实用新型内容
实用新型目的：本实用新型的目的在于提供一种成本较低、后期维护简单的有机硅废气处理装置。
为了实现上述目的，本实用新型采用了如下的技术方案：
有机硅废气处理装置，包括气液分离罐、废气输送管道、引风机和气体过滤器；所述气液分离罐入口连接有机废气输入管道，气液分离罐气体排放口通过引风机连接气体过滤器入口，废气输送管道呈C型，废气输送管道一端连接气体过滤器出口，废气输送管道另一端连接废气排放管道，废气输送管道中部设有接口，该接口与蓄热式氧化燃烧器的燃烧室废气入口连接。
进一步的，所述气液分离罐液体排放口连接废液回收罐。
进一步的，所述有机废气输入管道和废气排放管道均设有控制阀和压力表。
进一步的，所述废气输送管道铺设于蓄热式氧化燃烧器的燃烧室下方。
该装置在处理含有有机硅化合物的废气，特别是生产有机硅助剂所产生的废气时，具有更好的效果；相比现有蓄热式氧化燃烧器无法处理含有有机硅化合物的废气，或者只能采用集中燃烧，移动床等的复杂处理方式，采用该处理装置的成本更低，后期维护更简单。
图1为本实用新型的主视结构图。
图2为本实用新型的俯视结构图。
图中：1-有机废气输入管道；2-气液分离罐；3-废气输送管道；4-气体过滤器；5-蓄热式氧化燃烧器；6-引风机；7-废气排放管道。
下面结合附图对本实用新型做更进一步的解释。
如图1和2所示，本实用新型的有机硅废气处理装置，包括气液分离罐、废气管道、引风机和气体过滤器。
所述气液分离罐入口连接有机废气输入管道，气液分离罐气体排放口通过引风机连接气体过滤器入口，所述气液分离罐液体排放口连接废液回收罐(图中未示出)。
如图1所示，废气输送管道呈C型，铺设于蓄热式氧化燃烧器的燃烧室下方，废气管道两端高，中部低，废气输送管道一端连接气体过滤器出口，废气输送管道另一端连接废气排放管道，废气输送管道中部设有接口，该接口与蓄热式氧化燃烧器的燃烧室废气入口连接。废气管道底部设有排液口。
本实施例中，所述有机废气输入管道和废气排放管道均设有控制阀和压力表。控制阀为两个，其中一个位于管道相对于燃烧室的近端，其中一个位于管道相对于燃烧室的远端。
本实用新型有机硅废气处理装置是在典型的蓄热室氧化燃烧器的基础上，进行了以下的增加和改善。
将含有有机硅化合物的废气先通过有机废气输入管道通入气液分离罐中，经过凝华反应，此反应可以将大部分的可液态化废液进行回收利用，此废液一般可以做为蓄热室氧化燃烧器的燃料，达到经济节能的目的。经过气液分离罐后，再把所有废气汇总输送到为蓄热室氧化燃烧器的燃烧室进行处理。
将废气管道进行C型走向，此走向可将废气进行扰流和冲击，在冲击过程中可将废气中的液态成分凝结到管壁上，最后流到最下端的排液口排出，定期打开排液口，对废液进行量化和检测，可与生产量进行对比，会更好地计划生产任务。
引风机的废气出口增加气体过滤器，气体过滤器的作用与C型管道结构功能类似，同样可以起到过滤液态成分的作用，针对废气成分不同，可以在气体过滤器内增加不同种类过滤填充物。
废气在进入燃烧室时，有机硅化合物的含量已经大大减小，到时候产生的SiO
2物只需要定期打开燃烧室的人孔门进行清扫。
此清扫周期的检测方法：在蓄热式氧化燃烧器刚投入使用时，将系统切换到手动，只打开有机废气输入管道近端控制阀和废气排放管道远端控制阀，记录下有机废气输入管道和废气排放管道控制阀之间的压差，再只打开机废气输入管道远端控制阀和废气排放管道远端控制阀近端控制阀，记录下有机废气输入管道和废气排放管道控制阀之间的压，每月进行一次检测，当压差的差值相差20％时，就要进行清理。
以上所述仅是本实用新型的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本实用新型的保护范围。
