SMC微霧分離器的微霧分離器效果較好，適用于大型制冷系統(tǒng)，其結(jié)構(gòu)如圖7-3所示。壓縮機(jī)的排氣經(jīng)油分離器進(jìn)氣管沿切線方向進(jìn)入筒內(nèi)，隨即沿螺旋導(dǎo)向葉片高速旋轉(zhuǎn)并自上而下流動(dòng)。借離心力的作用將排氣中密度較大的油滴拋在筒壁上分離出來(lái)，沿壁流下，沉積在筒底部。蒸氣經(jīng)筒體中心的出氣管內(nèi)多孔板引出。筒側(cè)裝有浮球閥，當(dāng)油面上升到上限位時(shí)，潤(rùn)滑油通過(guò)浮球閥打開(kāi)閥芯，自動(dòng)向壓縮機(jī)曲軸箱或集油器排油。有的在油分離器外部還設(shè)有冷卻水套，使混合汽體在其中又受到冷卻水的冷卻并通過(guò)降低流速和改變流向的作用，進(jìn)一步得到分離。
日本進(jìn)口SMC微霧分離器的應(yīng)用也逐漸增多。結(jié)構(gòu)不同，三相分離器的控制方法也不同。兩種典型分離器的控制原理如下：
（1）油氣水混合物進(jìn)入分離器后，進(jìn)口分流器把混合物大致分成汽液兩相，液相進(jìn)入集液部分。集液部分有足夠的體積使自由水沉降至底部形成水層，其上是原油和含有較小水滴的乳狀油層。原油和乳狀油從擋板上面溢出。擋板下游的油面由液面控制器操縱出油閥控制于恒定的高度。水從擋板上游的出水口排出，油水界面控制器操縱排水閥的開(kāi)度，使油水界面保持在規(guī)定的高度。分離器的壓力由設(shè)在天然氣管線上的閥門(mén)控制。油微粒經(jīng)過(guò)濾材的擴(kuò)散作用，直接被濾材攔截以及慣性碰撞凝聚等機(jī)理，使壓縮空氣中的懸浮油微粒很快凝聚成大油滴，在重力作用下油集聚在油分芯底部，通過(guò)底部凹處回油管進(jìn)口返回機(jī)頭潤(rùn)滑油系統(tǒng)，從而使壓縮機(jī)排出更加純凈無(wú)油的壓縮空氣。壓縮空氣中的固體粒子經(jīng)過(guò)油分芯時(shí)滯留在過(guò)濾層中，這就導(dǎo)致了油分芯壓差（阻力）不斷增加。隨著油分芯使用時(shí)間增長(zhǎng)，當(dāng)油分芯壓差達(dá)到0.08到0.1Mpa時(shí)，濾芯必須更換，否則增加壓縮機(jī)運(yùn)行成本（耗電）。
