To understand the basi自妹c operation of a water separator, it's跳離 necessary to understand how these 內事devices work. These devices 來場are designed to sepa店計rate the different phases of wat木樹er and oil. When a process up朋信stream becomes upset, this間為 fluid may become trapped in the了看 water separator. To prevent this from 他她happening, a separate detection會那 system is installed at the water 技村separator. This detection system is use不紅d to prevent the buildup of oil鄉拍 in the water separat術西or.
The operation process of the water sepa飛吧rator unit involves three 熱個stages. In the first stage, the wa年樹ter passes through a coalescing filt書微er that separates impurit話廠ies from the oil. After that, the oi雪著l is pumped to a dirty oil tank via 但農an oil valve. The oil-wat謝光er mixture then moves downwards,媽空 moving slowly between catch plates. 務紅As more oil is removed, 數中the remaining water rises to the col快分lection space. Event兵得ually, the water in this stage is a白鐘lmost oil-free. The final d懂離ischarge is measured in ppm.
The oil content monitor (OCM) is 子就a device that continuously m鐵志easures the ppm of oil. It fee睡師ds its output signal to a control 就下unit. This device is used to preve低信nt oil-laden water from going overbo習空ard. It normally controls three 作物solenoid valves in the first 又要and second oil collecting chambers.小雪 In the lower part, 從請it controls the discharge side of the數些 oily water separator. Once it reaches電樂 the desired purity, it w兒頻ill pass through the fi房畫lter unit.
The water in the separator travels up 信個the plates. It forms glob自看ules and rises upward w風個ith the rising velocity 麗南of the water. They coal村南esce until they have enough risi遠低ng velocity to travel along t如城he surface of the plates. They then 討中break away from the plate at the pe坐了riphery. Meanwhile, the oil is森行 caught underneath the annul些妹ar baffle and leads 小北through the turbulen車厭t inlet area. The oil eventu海看ally collects in the 遠看dome.
In order for the oil to be separa間工ted from the water, the 視體oil needs to be removed fr她木om the wastewater. In低海 addition to removing oil, th坐制e water separator should be desi日空gned to limit the buildup of oil. An身草 oil-free effluent wit湖民h a lower "Re" value will not co也紅ntain a significant a金司mount of oil. Flow-through velocit線人ies of the separator should水錯 not exceed three feet per minute. 些房The second stage coale讀習scers are a necessary step for銀又 this process. The coales腦也cing surface area of the se一現parator holds small oil dropl聽我ets until they become larger.美場 The larger droplets rise空相 to the oil collecting chamber.土姐
The efficiency of centr是匠ifugal separation depends 又家on the difference betw都現een the two fluids. The greater the件慢 difference in specific gravity, t快藍he better the separation pro書件cess. It is important to unders火秒tand the particle size我船 of the separated water得高 as a threshold to determine whether th拿離e separation is effective or not理理. The operation process of the 市公water separator is also vita村身l to the efficiency of the se問鐵paration process. Without proper mainte會科nance, the separator can reduce or和窗 even eliminate the need fo東玩r water treatment.
