随着城市垃圾堆积,各种恶臭气体严重影响人们的日常生活。那么,臭气处理设备的除臭工艺类型有哪些呢?接下来,我将具体介绍一下。

臭气处理设备的除臭工艺类型

表面放电技术

表面放电技术是由Masuda等提出的。它的原理是利用电极放电,使放电从放电极沿陶瓷(柱型)表面延伸,在陶瓷表面形成许多细微的流柱通道。

用这种方法对甲苯、丙酮、氟氯烃等恶臭的处理,其处理效果较好,适合于难降解的恶臭的治理。但是,与其他放电方式相比,表面放电的功率消耗较大。放电过程发热比较严重,常需在反应器的外部强制冷却,能量利用率不高。另外,由于放电只集中在陶瓷表面附近,所提供的等离子体反应空间不够大,加上结构较复杂,不便于实际应用。

填充式反应器治理技术

填充式反应器是利用介电常数(一般在1000以上)较高的铁电体陶瓷颗粒作为填充物(如BaTIO3或SrTIO3等物质),当在两电极上施加交变的电压时,陶瓷颗粒就会被部分极化,从而在颗粒间形成很强的电场,使周围的气体局部放电产生等离子体,当恶臭通过填充物时,就很容易被氧化。用该法对低浓度的恶臭进行了实验研究。结果发现对甲苯的去除率达到了80%以上,对二氯甲烷的去除率也达到了80%。但这种反应器气体阻力大,能耗较高,而且铁电体材料也不易获取,使其实际应用受到限制。

臭气处理设备的除臭工艺类型

上海羿清环保公司主要采用生物除臭法进行臭气处理,其生产的生物滤池臭气处理设备能够有效处理臭气,而且没有二次污染产生,更加绿色节能环保。
