如何科学选择除臭设备
一般而言,化学除臭装置对恶臭浓度适应性最强,浓度较高,通常选用化学除臭装置。因恶臭污染物成分复杂,分为酸、碱、有机、无机等多种组分,为了达到较好的除臭,通常采用多种工艺相结合的方式进行恶臭处理,例如酸洗+碱洗+氧化,三个吸收塔串联。

如何科学选择除臭设备

一般而言,化学除臭装置对恶臭浓度适应性较强,浓度较高,通常选用化学除臭装置。因恶臭污染物成分复杂,分为酸、碱、有机、无机等多种组分,为了达到较好的除臭,通常采用多种工艺相结合的方式进行恶臭处理,例如酸洗+碱洗+氧化,三个吸收塔串联

生化脱臭装置对水溶性恶臭气体有很强的净化效果,如氨气、硫化氢等,吸附效率可达95%以上,且运行成本低,二次污染小,一般采用生物除臭设备处理

除臭设备

植物所用的液喷除臭方法,由于植物液对酸、碱、有机恶臭成分都能进行物理或化学反应,从而消除恶臭,且工程建设费用低廉,因此该方法也很广,我们常将其应用于低浓度的场所

采用活性炭吸附法,具有设备简单、成本低、维护方便等优点,但活性炭很容易饱和,而且在除臭设施中使用活性炭吸附法不能解吸,活性炭应用于除臭设施不能再生,活性炭是危废,处理费用较高,活性炭吸附法一般用作备用。

操作条件

除臭设备如需间歇运转,如日运转八小时,夜间不运转,建议不要使用生物除臭设备和活性炭吸附除臭设备;生物除臭设备一旦运行,就不能轻易停机,防止细菌在厌氧条件下发生变异,产生大量厌氧菌,导致设备本身成为恶臭污染源;如果每天运行八个小时,相对活性炭来说,负荷过大,极易.饱和,因此不建议使用;这种间歇运行的方式,通常我们采用化学除臭法或活性氧离子除臭法进行治理,并随用随开,使用比较经济。

天气效应

常用的干式处理,基本受气候影响小,湿法处理,受气候影响较大。例如污水处理厂,如果污水处理厂在我国北方,则不宜采用化学或生物除臭设备,因为污水厂一般位于室外,收集到的废液中一部分是新鲜空气,导致废气温度较低,化学处理设备容易结冰,而生物处理设备由于温度过低,微生物容易呼吸,从而造成设备处理能力低下。但是如果是污泥处置、垃圾处理等工况,固废往往有处理车间,中间有暖气,废气处理设备处理常温气体,就可使用。湿法处理法在我国北方采用除臭室,一般需要使用除臭室,便于设备防冻。因若采用蒸汽、热水、电伴热等保温措施,必然消耗大量能源,而且增加了设备建设费用。因此如果较小的工程,北方我们建议采用干处理的方法,而南方的限制少一些。

上海羿清环保公司是一家以生产除臭设备为核心的环保公司,所生产的生物滤池除臭装置可有效地处理恶臭废气,且无二次污染,深受社会各界人士的好评。
