Abstract
The invention discloses an industrial waste oil treatment process which comprises the following steps: dissolving ethylene glycol butyl ether and a water-coal-slurry additive in industrial waste oil, stirring at normal temperature, and forming a mixed liquid; and adding pulverized coal and water into the mixed liquid, and continuously stirring to form a water-coal-slurry product which is not layered. According to the process, the original scraped waste oil which cannot be directly discharged is changed into a valuable material, the subsequent treatment cost is saved, and the heating value of the water-coal-slurry product prepared by utilizing the industrial waste oil is correspondingly improved. Moreover, the problem that the traditional organic waste liquid water coal slurry is low in stability is solved according to a coupling agent stabilization technology provided by the invention, the problem of the system stability of the product can be fundamentally solved, the stability of the product is improved, oil-water separation is not generated due to long-term standing, the operations of loading and unloading, storage, pipeline transportation and atomization space combustion are easy, and the process can be used for oil, gas and coal combustion in power station boilers, industrial boilers and industrial furnaces.
Description
Technical field
The present invention relates to industrial waste oil process field, specially refer to the industrial waste oil treatment process of the equipment oil that above industrial equipments, use is scrapped (comprising hydraulic efficiency oil, gear wet goods), Industry Waste machine oil, industrial abandoned processing wet goods.
Background technology
Various device oil (comprising hydraulic efficiency oil, gear wet goods), Industry Waste machine oil, the industrial abandoned processing wet goods that above industrial machinery, must use; play the lubrication protection effect to equipment or cutter, but final these oil products all can cause and can not continue to use and scrap because of reasons such as having sneaked into moisture, mechanical impurity, oxidation, acidifying.Degradation does not reach while requirement and will scrap, but because the mineral oil that wherein contains and other organic additive compositions, and COD value (chemical oxygen demand) is very up to less than direct emission standard.Producer or stealthily discharge in the past, not only caused great destruction to environment, and offended the corresponding environmental law Laws & Regulations of China.The environmental protection company of giving corresponding qualification processes, but processing costs high generally 800-2000 yuan/ton not etc., brought many economical load to enterprise like this.Prior art also has by coal water slurry processes industrial waste oil, but the fuel value of coal water slurry is not high, can not thoroughly effectively solve the wasting of resources and problem of environmental pollution, and the more important thing is the problem that also exists system stability relatively poor, can there is oily water separation in long-time leaving standstill, be not easy to handling, storage, pipeline conveying and atomization space burning etc.
Therefore, need a kind of high performance fuel and preparation method thereof, can not only effectively process industrial waste oil, improve fuel combustion value, can thoroughly effectively solve the wasting of resources and problem of environmental pollution, can also fundamentally solve the system stability problem of product, improve product stability, there is not oily water separation in long-time leaving standstill, is easy to handling, storage, pipeline conveying and atomization space burning etc.
Summary of the invention
In view of this, the object of this patent is to provide a kind of industrial waste oil treatment process.This technique not only can turn waste into wealth originally scrapping the waste oil that can not directly discharge, save subsequent disposal expense, utilize the coal water slurry product thermal value that industrial waste oil is made also to obtain corresponding raising simultaneously, and couplant stabilization technique provided by the invention has thoroughly solved the stability problem of traditional Orgnic Waste Liquid CWS, can also fundamentally solve the system stability problem of product, improve product stability, there is not oily water separation in long-time leaving standstill, be easy to handling, storage, pipeline conveying and atomization space burning etc., can be used for station boiler, Industrial Boiler and Industrial Stoves are for oil, for gas, for coal combustion.
A kind of industrial waste oil treatment process of the present invention adds ethylene glycol monobutyl ether, slurries additive agent, coal dust, water to form not stratified coal water slurry product in industrial waste oil.

In above-described embodiment, also can adopt other defoamers that can realize same goal of the invention.
The characteristic of the waste oil water coal slurry that the industrial waste oil treatment process of above-described embodiment obtains sees the following form:
| Embodiment | Calorific value | Rheological | Efficiency of combustion |
| Embodiment mono- | 19.8MJ/㎏ | B level | 98.9 |
| Embodiment bis- | 22.0MJ/㎏ | B level | 99.1 |
| Embodiment tri- | 22.6MJ/㎏ | B level | 98.7 |
More than the stability of the high performance fuel (coal water slurry) that above-described embodiment makes all can reach B level.Detection method is: the sample that takes a morsel, be placed in sealed vessel, and quiet a surname's for some time, then observe its bleed situation, precipitation situation, slurry regenerative power, withered property, mobility etc.
Test as follows respectively processing by water-based metal working fluid process for treating waste liquor the waste liquor coal liquid obtaining in above-described embodiment:
Measure in advance the concentration of waste liquor coal liquid, then get six bottles, (in every bottle, quantitatively filling 200ml, sealing) leaves standstill, and within every 15 days, gets one bottle and measures change in concentration.Measuring method is: the slurry concentration of measuring upper strata 50ml and orlop 50ml.
Two, experimental result
1, the variation of upper strata 50ml: the time is longer, the concentration of slurry is more and more lower, the fastest variation in first 10 days, changes afterwards little.
2, the variation of the 50ml of lower floor: the fastest variation in first 10 days, change afterwards more and more less and tend to be steady.
3, in 3 months, there is not hard-caked sediment, very good of stability is described.
A level: stability is best, slurry keeps original state, is uniformly distributed, and produces without bleed and precipitation.
, there is the generation of a small amount of bleed or soft precipitation in B level: stability is better.
C level: slurry stability is poor, has precipitation to produce, has bleed, density distribution inhomogeneous, renewable through stirring, good flowing properties, and slurry is even.
D level: stability is the poorest, density distribution is obviously inhomogeneous, and producing hard-caked sediment cannot regenerate.
As seen from the above-described embodiment, and for above technique effect, the proportioning of embodiment bis-and processing parameter, result of use is best, is obviously better than other embodiment, is the best.
Finally explanation is, above embodiment is only in order to the technical scheme of this patent to be described and unrestricted, although this patent is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement (such as adding proportion have a little that adjust, Industry Waste oil product source may be other mechanical means sources etc. as civilian machinery) the technical scheme of this patent, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
