Abstract
The invention relates to a regeneration process of waste transformer oil. The regeneration process comprise the following steps of precipitating a majority of contaminants from the waste transformer oil by heating, filtering out residual suspended impurities in the oil body by virtue of an industrial filter press and a 1000mesh filter screen to obtain the finished product if the oil body already becomes almost colorless faint yellow and carrying out adsorption bleaching on the oil body by virtue of activated clay and filtering to obtain the finished product if the oil body has darker color.
Description
Technical field
The invention provides a kind of reclaiming process of useless transformer oil, specifically refer to utilize discarded transformer oil to change purposes after manipulation of regeneration, substitute white mineral oil in some field.
Background technology
Will change after transformer oil uses certain time limit in transformer, and be replaced out by new transformer oil, be useless transformer oil.Oil fuel can be worked as, but calorific value is low and produce a large amount of dense smoke polluted air; Not only waste also contaminate environment is outwelled as waste oil; Will consume a large amount of industrial white mineral oil every year in plastic working industry, the transformer oil after manipulation of regeneration can Part Substitution white mineral oil; Make a general survey of waste oil regeneration to be " acid-base method ", the throw out leached after dense sulfuric acid treatment is strong acid character, in any case process all can contaminate environment or air; The time cycle of " acid-base method " manipulation of regeneration is long, and need expend soda acid industrial chemicals and heating fuel, tooling cost is high.
Summary of the invention
The invention provides a kind of reclaiming process of useless transformer oil, namely discarded transformer oil is reclaimed, few for metal ingredient contained by it, the feature that plastic working industry is not high to white mineral oil quality requirements, after " non-acid-base method " regenerates processing treatment, the industrial white mineral oil that the industries such as substituted for plastic processing use.
The technical solution adopted in the present invention is: first, utilizes the physical property that oil body viscosity and temperature are inversely proportional to, and is placed in by discarded transformer oil in reactor or metal vessel, through heating, leaves standstill, and is settled out large portion dirt and gets rid of moisture; Then use the press filtration of industrial pressure filter height mesh filter screen, suspended impurity composition remaining in waste oil is leached; Last according to oil body shade, determine whether use atlapulgite adsorption bleaching.When oil body color connects subdiaphanous faint yellow, be finished product.
The invention has the beneficial effects as follows: recycle discarded renewable resources and substitute white mineral oil, minimizing industrial raw material consumption and waste are to the pollution of air, environment; Adopt the method reject suspended impurity of press filtration, without soda acid, shorten the process-cycle, cut down finished cost and avoid secondary waste to the pollution of environment.
Claims (1)
1. a useless transformer oil regeneration technology, is characterized in that: first, and useless transformer oil is placed in reactor or metal vessel, heat 100-120 DEG C, maintain 1-3 hour to get rid of moisture depending on water content difference, then Temperature fall leaves standstill 24 hours, is settled out most of suspended impurity;
Second step carries out press filtration: use industrial pressure filter and adopt high order number filter screen, being leached by the remaining suspension impurity in oil body, if leach the oil body after suspended impurity namely can be finished product close to certified products color;
3rd step adsorption bleaching: if the oil body color after high order press filtration is darker, also through adsorption bleaching, oil body must be warmed to 130 DEG C, according to oil body shade, by weight percentage, get the atlapulgite of oil body weight 1%-4%, when to oil body moderate-speed mixer, add carclazyte, stir 1 hour again, stop stirring, oil body static state kept temperature 110-120 DEG C after 4 hours, cooled, precipitated, leaches the finished product being intimate certified products color.
