廢潤滑油再生技術(shù)簡介
一、影響潤滑油質(zhì)量的因素
回收的廢潤滑油中，存在非烴類、烯烴類、稠環(huán)芳烴、金屬離子；機械雜質(zhì)、金屬微小顆粒；瀝青質(zhì)、膠質(zhì)等有害物質(zhì)。這些有害物質(zhì)的存在，互為引發(fā)劑、相互提供反應(yīng)物和催化物質(zhì)。在外部因素：光、溫度和空氣中氧氣等的作用下產(chǎn)生聚合、氧化等化學變化，潤滑油的安定性被破壞，表現(xiàn)為變黑、沉渣等現(xiàn)象。
I、The factors that influence the quality of lubricating oil
The existence of hydrocarbon mixtures(non-hydrocarbons、alkenes、condensed-nuclei aromatics ), metal ions, mechanical impurities, metal particles, asphaltine、colloid in the recycling of waste lubricating oil will influence the quality of lubricating oil. These harmful substances can react with each other under the external factors (oxygen, light and temperature); chemical changes (polyreaction, oxidation) may occur at this time also, creating black colors or some grain stillages.
二、本公司開發(fā)了一套回收廢潤滑油再生技術(shù)。
本技術(shù)采用化學處理過程中催化劑的作用。我公司開發(fā)了一種復合催化劑，在它的催化作用下，內(nèi)部因素的各有害物質(zhì)被選擇性的進行了處理，例如：聚合、屏蔽、鈍化等并***終以殘渣的形式排出。從而達到除去廢潤滑油中的不安定因素，使其還原再生，成為合格潤滑油基礎(chǔ)油。
該項技術(shù)既不同于傳統(tǒng)的硫酸蒸餾，也不同于目前的油蒸餾催化加氫技術(shù)。傳統(tǒng)蒸餾技術(shù)產(chǎn)生的廢渣和廢氣對環(huán)境污染極為嚴重。而后者得到的油又極易氧化變色還有臭味。本公司這套技術(shù)的工藝過程為：將回收的各種廢潤滑油(包括汽、柴機潤滑油等幾乎所有可以回收的廢棄油)進行催化處理后，再經(jīng)蒸餾后制得與原廢潤滑油相同的再生潤滑油基礎(chǔ)油，它不會產(chǎn)生氧化變色，也沒有臭味產(chǎn)生。殘留的廢渣還可做燃料使用，不會對環(huán)境產(chǎn)生二次污染。該技術(shù)自動化控制程度高，設(shè)備操作簡單，沒有復雜的操作控制，易學易懂，勞動強度無需特別1～2人即可。
II、Our company has developed a set of recycling waste oil regeneration technique.
This technology is using the principle of catalysts in chemical process. We developed an alkaline compound catalyst which can take some selective chemical reactions between these harmful substances(like polymerization, shielding, passivation), discharge the harmful substance in the form of residue,remove the unsafe factor during use of waste lubricating oil, and then refine the waste oil, get the qualified base lubricating oil.
The technology is different from the traditional distillation, and also different from the current favorite technology which using the steam heated method to regenerate the waste oil. Just for the waste residue and waste gas created by the traditional distillation way will easily pollute our environment. And the oil gets by the latter way will discolored by oxidation with the bad smell.
The technology process of our company: the reclaimed waste lubricating oil (including gasoline engine oil / diesel engine oil and almost all waste recoverable oil) will be treated with catalysts first, and then get the regenerated lubricating base oil which is the same as the origin waste oil by distillation. This base oil can not be discolored by oxidation and no bad smell release; the waste residue can be used as fuel so as to reduce the pollution of environment. With the high degree of automation control technology, our equipment easy to be operated by one or two workers without complicated operation.
三、工藝過程
原料廢潤滑油經(jīng)脫除機械雜質(zhì)后，進入化學處理釜，加入催化劑的水溶液，常溫常壓下攪拌反應(yīng)。催化處理后的原料經(jīng)泵打入間歇式蒸餾釜內(nèi)，在高真空條件下進行蒸餾，依次蒸出水、燃料油、各種沸程的潤滑油基礎(chǔ)油經(jīng)過專用冷凍機冷卻后回收。***后排出蒸餾殘渣(可作燃料)。蒸餾過程中廢潤滑油采用循環(huán)加熱的手段；加熱熱源可采用電、燃料油、天然氣、煤等。配有廢氣處理器對真空排出的氣體進行凈化處理。
III、technological process
After remove the mechanical impurity, oil will treat by the chemical kettle, then add the catalyst aqueous solution in the kettle and stir it under the normal temperature and pressure. The raw material will be pumped into intermittent distillation kettle after catalytic treatment, under the high vacuum condition, the distilled water、fuel oil and base oil will be extract in turn from distillation kettle. After any kinds of boiling-range base oil cools off by the dedicated chiller plant, it can be recycled. And the machine will discharge the waste residue (can be used as fuel).We take hydronic heating method to treat the waste oil during the process of distillation ; you can use electricity, fuel oil, natural gas and coal, etc. to heat it；Our machine equipped with waste gas processor for gas purification treatment .
