美国尼科NICO进口污水处理鼓风机(曝气风机)是把原动机的机械能转变为气体压力能的一种旋转叶片机械。当气体通过进气室均匀地进入叶轮后,在旋转的叶片中受离心力作用以及在叶轮中的扩压作用,使气体获得压力能和速度能,由叶轮高速流出的气体经扩压器的扩压作用,使一部分速度能转变成压力能。如此气体经过几级连续压缩,获得所要求的压力。因此连续供气是离心鼓风的一大特点。污水处理风机也称污水处理鼓风机,在污水处理的生物接触氧化法工艺中,微生物所需的氧气通过污水处理风机曝气供给。其原理是在池内设置填料,池底曝气对污水进行充氧,并使池体内污水处于流动状态,以保证污水同浸没在污水中的填料充分接触,避免生物接触氧化池中存在污水与填料接触不均的缺陷,我们称具有这种作用的鼓风机为污水处理风机。

1.本系列产品为单吸入多级双支撑结构,电动机和鼓风机安装在同一底座上。曝气用鼓风机用弹性联轴器直接传动。
2.鼓风机的进出口均为圆形,出口方向可以根据用户的需要垂直向上或向水平左右(从电机端看)。进气口装有空气过滤器和蝶阀,蝶阀的作用是调节鼓风机的性能,以适应管网特性要求的变化。
3.本系列鼓风机属无机械摩擦机械,和罗茨鼓风机相比噪音低、维修频率低、使用周期长。
4.机壳:鼓风机机壳由进气室、中间机壳和排气蜗壳组成,材料为铸铁。进气室、中间机壳和排气蜗壳都没有水平分面,彼此之间由垂直分面的止口定位,在圆周方向用八个拉杆螺栓连接,紧固成为整体机壳。为防止机壳内气体外泄,进气室、中间机壳和排气蜗壳之间止口处装有“O”型密封圈。根据气动设计要求,在叶轮出口设有无叶扩压器,与弯道、回流式隔板构成级间隔板,将各级叶轮分隔开并构成连续的流道。本鼓风机是由中间机壳组合而成的。
5.叶轮:鼓风机叶轮全部采用铝合金离心浇铸而成,叶轮精加工后作静平衡校正。叶轮与主轴采用间隙配合键连接。组装打表后作动平衡校正。保证鼓风机稳定运行。和钢制铆焊接叶轮相比减少自重,提高效率。
6.轴承:本系列鼓风机为无油机械,两端采用流动轴承,润滑脂润滑。轴承座以止口定位用螺栓连接在进气的排气蜗壳上。滚动轴承定期注入干油润滑。在出口端轴承座上设有水冷却装置,以满足冷却轴承温度的需要。
7.密封:本鼓风机靠叶轮进口圈外缘、叶轮轮毂与中间机壳隔板相应部位之间的装配间隙来减少内部的气体泄漏。机壳两端轴孔处设有槽型密封防止气体外泄。
8.该污水处理离心鼓风机主要用于环保和化工领域,特别是污水处理工艺流程中的曝气场合,也可用于其它输送空气或无毒、无腐蚀性气体的场合。
1,用来给污水处理系统供氧,保证生化系统的溶解氧含量,为好氧微生物提供好氧环境。
2,用来搅拌,混合水体,或者是为了促进药剂和水的混合,也或者是防止污泥沉降。一般采用罗茨风机、悬浮风机、回转风机等。
有两种用途,一是给生化好氧菌增加氧气,保障它们生存环境,达到污水处理的需要。二是通风,由于污水处理多数都采用生化反应,会产生一些沼气和其它分解气体,气味难闻同时也带有一定的危险性,为了保证安全和改善环境,要对现场环境进行通风。
鼓风机主要由下列六部分组成:电机、空气过滤器、鼓风机本体、空气室、底座(兼油箱)、滴油嘴。鼓风机靠汽缸内偏置的转子偏心运转,并使转子槽中的叶片之间的容积变化将空气吸入、压缩、吐出。在运转中利用鼓风机的压力差自动将润滑送到滴油嘴,滴入汽缸内以减少摩擦及噪声,同时可保持汽缸内气体不回流,此类鼓风机又称为滑片式鼓风机。
