Description
Technical field
The present invention relates to a kind of methods of the resource reutilization of waste, are related specifically to a kind of purification process of used oil
The method of recycling.
Background technology
From the point of view of current machine oil service condition, the machine oil usage amount in China is located at world forefront, but waste oil is sharp again
With rate insufficient developed country 1/3rd, and most of waste oil is all wasted as burning oil, and which results in serious
The wasting of resources.Therefore, the use of regenerating waste oil production is a beneficial thing benefited the nation and the people, based on such national conditions, and utilizes used oil
Purifying and prepare apply to concrete production the method for releasing agent have not been reported at present.
Invention content
The defects of purpose of the present invention is intended to overcome the prior art wastes the serious specific national conditions of situation according to fuel oil,
It is proposed a kind of used oil purification treating method for purifying recycling again for used oil.
Used oil purification treating method of the present invention, purification process process are：Heat up sedimentation-pickling-alkali
It wash-filters, the specific steps are：
A. heating sedimentation removal of impurities：Used oil is added in a device, and temperature is risen to 70-80 DEG C, stirs 25-30min, then adding
After standing 3 hours under heat condition, the upper strata of used oil is taken out to remove the insoluble impurities sunk to the bottom；
B. pickling：The step a used oil taken out is heated to 30-35 DEG C, it is middle after temperature stabilization to add in machine oil volume 6-8%'s
Sulfuric acid solution, and control to add in 30min and complete；
C. alkali cleaning：Maintain the temperature at 35 DEG C hereinafter, with sodium carbonate liquor adjust used oil pH value, the value of PH is adjusted to 7-8；
D. it filters：It is clean by being obtained by filtration while hot with vacuum oil-filter through the used oil after step b, step c pickling alkali cleanings
Used oil.
Pickling described in step b after sulfuric acid solution adds, adds a concentration of 10% soda bath, and the amount of addition is
The 1% of machine oil volume.
In used oil decolorization after being filtered to step d, aluminium polychloride is matched using carclazyte-cationic and acrylamide
Composite decoloring agent carries out decolorization.
In the present invention, heating sedimentation is to take out the small impurity of solid insoluble in used oil.And pickling be with sulfuric acid and
A small amount of soda bath carries out pickling, and to remove the impurity such as colloid, pitch, caustic soda can play the role of flocculated, reinforcement impurity
Separation.Alkali cleaning mainly neutralizes the acid left, and pH value is modulated alkalescent to provide more anion, and this is conducive to
It is acted on the decolorising agent of cation and makes decoloration more complete.And the damage of concrete performance under acidic environment can be mitigated
It loses.Finally by filtering, removal passes through the impurity after pickling and alkali cleaning.After filtering, according to the color for crossing oil after filter
Decide whether to carry out decolorization, decolorization is compound de- with aluminium polychloride using carclazyte-cationic and acrylamide
Toner carries out decolorization.Composite decoloring agent can ensure ensure inexpensive production on the basis of high-effect decoloration.
The purification treating method of used oil of the present invention, design theory are specially：
1st, pickling：Added in acid cleaning process sulfuric acid be conducive to remove colloid in used oil, pitch shape impurity, and add in a little
Soda bath can play flocculation in used oil removal of impurities system, the contaminant particles in used oil is made drastically to become larger to be formed
Floc sedimentation, so as to accelerate, foreign particle is sunk to the bottom and filters exclusion.
2nd, alkali cleaning：The purpose of alkali cleaning is mainly there are two reason, first, prepared releasing agent is mainly used in concrete
In system, thus the PH of releasing agent should be adjusted to alkalinity can mitigate influence of the releasing agent to concrete system.Second, by useless machine
The pH value modulation alkali cleaning of oil can increase the number of the anion in used oil system, and the number of anion is more in system
Then more be conducive to the combination of zwitterion in decoloring reaction, so as to make the decoloration of used oil more completely and to obtain quality higher
Product.
3rd, it decolourizes：Carclazyte is fabulous decolorising agent product, but largely uses carclazyte can be to product as decolorising agent
Performance generates certain influence.And the present invention matches aluminium polychloride decoloration system using carclazyte-cationic-type polyacrylamide.Sun
Polyacrylamide（CPAM）It is good decolorising agent product, can acts on and carry out with the impurity of the anion in used oil
Flocculation sediment, insoluble in organic solvent, and it is environmentally protective, it is splendid environmentally friendly decolorising agent.But CPAM is in reality
The cost used in production process is higher, therefore inorganic type aluminium polychloride, polyaluminium are added in entire decoloration system
Aluminium and CPAM are used in combination and can effectively reduce by 80% CPAM dosages and achieved the purpose that reduce production cost with this.
The purification treating method of used oil of the present invention can make used oil achieve the purpose that recycling, so as to reduce
The waste of the energy.Purified treated that used oil is used in the releasing agent of concrete, and this product is in concrete works
It can also ensure that the surface of concrete is smooth without being influenced by demoulding on basis using the component that can ensure concrete.
Specific embodiment
With reference to embodiment, the present invention is described further, but not limited to the examples.
