Abstract
The present invention relates to the comprehensive utilization of the clay oil residue of refined transformer oil and turbine oil, which belongs to a method for reclaiming lubricating oil from the clay oil residue of the refined transformer oil and the turbine oil. In the present invention, the clay oil residue and additive are mixed, stirred and heated to recover oil by reaction, and the deoiled clay slag is used as raw materials of brick making. The method of the present invention has the characteristics of thorough reclaiming of the oil in the slag, simplicity, convenience, easy operation, high processing speed, high economic benefit, no secondary pollution, etc.
Description
The invention belongs to the carclazyte dregs of fat comprehensive utilization method that produces in a kind of oil refining industry clay treatment.
Industrially often sorbent materials such as bone black, gac, carclazyte or diatomite are carried out absorption reaction with lube stock oil heated and stirred in order to obtain quality lubricating oil preferably, filter then product lubricating oil.What this refining with adsorbents process will produce the relatively large carclazyte dregs of fat, slag consists of carclazyte, the lubricating oil that is adsorbing, gum asphalt and other impurity etc.The lubricating oil types difference, just different with the adsorptive power between the sorbent material, the character of the carclazyte dregs of fat of generation is also inequality, so each carclazyte dregs of fat all should have oneself, the most easy recoverying and utilizing method.Invented a kind of method of from the useless carclazyte of refined wax, extracting paraffin as CN88105504A, this method is used to handle the lower lubricating oil carclazyte dregs of fat of viscosity and is not suitable for, and reason is that this invention adding quantity of solvent is very big, the reaction times is long, processing power is low, cost is high, environment is caused secondary pollution.The comprehensive utilization of the low-viscosity oil carclazyte dregs of fat is studied lessly both at home and abroad, does not also have the patent of this respect.
The purpose of this invention is to provide a kind of economical and effective, the method for simple and easy to do comprehensive utilization transformer oil, the turbine oil carclazyte dregs of fat.
This invention is to realize like this, the carclazyte dregs of fat of transformer oil or turbine oil and water or sodium hydroxide solution or other basic solution are mixed together, stir reacting by heating down, make reactant in the pasty state, reclaim the oil of desorb, the clay dregs of getting behind the oil adds a certain amount of other material, and sintering forms brick after the extrusion forming.
In the method for the present invention, the carclazyte dregs of fat, water (or 0.5-2% lime slurry, 0.5-2% sodium hydroxide or other basic solution) were by weight 1: 0.5---and 1 mixed, optimum proportion are 1: 0.5-0.8.
Heating in the inventive method can be coal, electric furnace, steam or other type of heating, but all reactant should be heated to 90-100 ℃, and fully stirs in heat-processed, makes the entire reaction thing in the pasty state.
After refiltered oil in the inventive method is meant that reactant in the pasty state, continue to stir 1-5 minutes, Best Times 2 minutes, make oil in the carclazyte dregs of fat all by water or basic solution desorption, then the oil of desorb is directly emitted, or stop to stir the back and add a small amount of cold water in the reaction vessel and make oil float combine in liquid level to be reclaimed, the oil of recovery also can be used as the base oil of production machinery oil and linen softening oil again through clay-filtered product transformer oil and the turbine oil of promptly becoming.
Clay dregs brickmaking after of the present invention the deoiling is with flyash, the clay dregs that deoils, binding agent (as poly ethylene glycol, methylcellulose gum, dextrin, polyvinyl alcohol etc.), after 1: 0.3: 0.002 mixed extrusion forming, in 1100---1230 ℃ of following sintering form.
Method synthesis of the present invention utilizes transformer oil, the turbine oil carclazyte dregs of fat, and not only simple and easy to do, processing speed is fast, reclaim thoroughly, do not have any secondary pollution, and show that in the result that Nanchong factory carries out pilot scale this method also has bigger economic benefit and good social benefit.
Following examples will help further to understand the present invention.
Embodiment one:
The carclazyte dregs of fat of 1000 gram transformer oil or turbine oil and 700 gram water are mixed together, being heated to 95 ℃ under stirring makes reactant be even pasty state, continued stirring reaction 2 minutes, stop to stir after making the whole desorbs of lubricating oil in the carclazyte dregs of fat, the oil of desorption directly emitted or add a small amount of cold water and make oil float combine in liquid level to be reclaimed, get 250 gram oil, this oil also can be used as the base oil of machinery oil or linen softening oil again through a small amount of clay-filtered product transformer oil or turbine oil of promptly getting.
Embodiment two:
The carclazyte dregs of fat of 1000 gram transformer oil or turbine oil and the sodium hydroxide solution or the lime slurry of 700 grams 1%, or other basic solution mixes, be heated to 95 ℃ under stirring, make reactant be even pasty state, continue to stir 2 minutes, make oil all from the carclazyte dregs of fat, after the desorption, reclaim and obtain 260 gram oil.
Embodiment three:
Get the carclazyte dregs of fat behind the oil in 1: 0.3: 0.002 the ratio mixing of weight ratio of flyash (or clay), slag, binding agent (methylcellulose gum, polyvinyl alcohol etc.), through 250-300kg/cm
2After the pressure compression moulding, seasoning, then 1100---1230 ℃ of following high temperature sinterings form brick.
Claims (3)
1, a kind of method that reclaims waste oil from the carclazyte dregs of fat is characterized in that: the carclazyte dregs of fat, water (or lime slurry of 0.5～1%) is 1: 0.7 mixed by weight, be heated to 90～100 ℃ under stirring, make reactant in the pasty state, leave standstill, reclaim and separate the oil of sucking-off.
2. in accordance with the method for claim 1, it is characterized in that: the carclazyte dregs of fat are oil refining industry carclazyte refining with adsorbents transformer oil, the carclazyte dregs of fat that produce during turbine oil.
3. it is characterized in that in accordance with the method for claim 1: heating can be adopted steam, coal or electric furnace heating.
