油霧凈化器是一種應(yīng)用于機(jī)械加工中用冷卻劑冷卻工件而產(chǎn)生煙霧的收集設(shè)備，設(shè)備體積小，收集效率高達(dá)95%以上，可以應(yīng)用于機(jī)械加工中各種油霧/煙氣的收集處理。
    Oil mist purifier is a kind of collection equipment used to produce smoke by cooling the workpiece in mechanical processing. The equipment is small in volume and more than 95% of the collection efficiency. It can be applied to the collection and treatment of various oil fogs / fumes in mechanical processing.
    一般情況下，機(jī)械霧化過程產(chǎn)生的油霧主要以液滴形態(tài)存在，液滴直徑范圍較寬，通常為2-10um。蒸發(fā)產(chǎn)生的油蒸汽在冷凝過程中也會(huì)形成直徑非常細(xì)小的冷凝懸浮體，粒徑通常為2um以下。
    Generally, the oil mist produced by mechanical atomization is mainly in the form of droplets, and the droplet diameter is wide, usually 2-10um. The evaporated oil vapor also forms a very small condensate suspension in the condensation process. The particle size is usually less than 2um.


    油蒸汽和大顆粒液滴對(duì)人體肺部的危害相對(duì)較小。以油蒸汽形態(tài)存在的油霧被吸入肺部又被呼出，它們并不會(huì)被肺泡捕獲，而大顆粒的油滴無法通過鼻子和支氣管進(jìn)入肺部。只有以液滴形式存在，且直徑小于5um的油霧顆粒才能順利到達(dá)肺泡，并在肺部沉淀，從而造成對(duì)人體的危害。
    The harm of oil vapor and large droplets to human lungs is relatively small. The oil mist that exists in the form of oil vapor is inhaled and exhaled, and they are not captured by the alveoli, and the large particles of oil can not enter the lungs through the nose and bronchus. Only in the form of droplets, and less than 5um diameter of oil mist particles can smoothly reach the alveoli, and precipitate in the lungs, resulting in harm to the human body.
    油霧凈化器采用機(jī)械分離和靜電沉積技術(shù)。機(jī)械分離是使用含油霧的氣體與特制的擋板濾網(wǎng)撞擊或者急劇的改變氣流方向，利用慣性力分離并捕集油氣，將進(jìn)入凈化設(shè)備的含油氣體中的大顆粒油滴或水滴過濾，它用于油霧凈化設(shè)備靜電場(chǎng)的前級(jí)除油氣，能去除5-20um以上的粗微塵，靜電沉積技術(shù)是利用電力進(jìn)行收集油霧的裝置，它涉及到電暈放電、氣體電離和油霧塵粒荷電、荷電油霧塵粒的遷移與捕集、油霧等過程，油霧凈化設(shè)備工作原理是，在油霧凈化設(shè)備中的電場(chǎng)箱中，兩個(gè)曲率半徑相差很大的金屬陽(yáng)極和陰極上，通以高壓直流電，在兩極間維護(hù)一個(gè)中以使氣體電離的靜電場(chǎng)，氣體電離后所產(chǎn)生的電子、陰離子或陽(yáng)離子附著在通過電場(chǎng)的油霧塵粒上，使油霧塵粒帶電，荷電油霧塵粒在電場(chǎng)力的作用下，便向極性相反的電極運(yùn)動(dòng)，從而沉積在集塵電極上，凝聚成油滴和水滴，從而使油、水和氣體分離。附著在集塵電極板上的乳化液和水分，因重力作用到油霧凈化設(shè)備下部的集油槽內(nèi)。
    Oil mist purifier adopts mechanical separation and electrostatic deposition technology. Mechanical separation is the use of gas containing oil mist with a special baffle filter or a sharp change in the direction of the air flow, using the inertial force to separate and capture oil and gas, and will enter the oil droplets or water droplets in the oil containing gas of the purification equipment. It is used to remove the oil and gas in the electrostatic field of the oil mist purification equipment and can remove more than 5-20um. The electrostatic deposition technology is a device for collecting oil mist by electric power. It involves the process of corona discharge, gas ionization and oil mist dust charge, migration and capture of charge oil mist particles, oil mist removal and so on. The principle of oil mist purification equipment is that two curvature half in the electric field box in the oil mist purification equipment. On the anode and the cathode with large diameter, the electrostatic field is maintained between the two poles by high voltage DC, and the electrons, anions or cations produced by the ionization of the gas are attached to the oil mist particles through the electric field to make the oil mist particles charged and the charged oil mist particles are under the action of the electric field force. They move to electrodes with opposite polarity, so that they are deposited on the dust collecting electrodes, condensing them into oil droplets and water droplets, so that oil, water and gas are separated. The emulsion and moisture attached to the dust collecting electrode plate are acted on by gravity to the oil collecting tank at the lower part of the oil mist purifying equipment.
