In above-described embodiment, additive is generally emulsifying agent, defoamer etc., but adds pigment, mask agent, other functional additives, all the character of the present invention is not had substantial effect, only adds for not congenerous alternative.
In above-described embodiment, it is possible to adopt other defoamers that can realize same goal of the invention.
The characteristic of the waste oil coal water 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 one | 19.8MJ/�K | B level | 98.9 |
| Embodiment two | 22.0MJ/�K | B level | 99.1 |
| Embodiment three | 22.6MJ/�K | B level | 98.7 |
The stability of the high performance fuel (coal water slurry) that above-described embodiment is obtained all can reach more than B level. Detection method is: gets a small amount of sample, is placed in sealed vessel, quiet a surname's for some time, then observes its analysis regimen condition, precipitation situation, slurry body regenerative power, withered property, mobility etc.
Carry out respectively testing as follows by the waste liquor coal liquid obtained by the process of water-based metal working fluid process for treating waste liquor in above-described embodiment:
Measuring the concentration of waste liquor coal liquid in advance, then get six bottles, (quantitatively filling 200ml in every bottle, sealing) leaves standstill, and within every 15 days, gets one bottle and measures change in concentration. Measuring method is: the slurry concentration measuring upper strata 50ml and orlop 50ml.
Two, experimental result
1, the change of upper strata 50ml: the time is more long, the concentration of slurry is more and more lower, and the fastest change in first 10 days, change is little afterwards.
2, the change of lower floor 50ml: the fastest change in first 10 days, changes more and more less afterwards and tends to be steady.
3, in 3 months, hard-caked sediment does not occur, stability very good is described.
A level: stability is best, slurry body keeps original state, is uniformly distributed, and produces without analysis water and precipitation.
, there is the generation of a small amount of analysis water or soft precipitation in B level: stability is better.
C level: slurry stability is poor, has precipitation to produce, has analysis water, density distribution uneven, and renewable through stirring, good flowing properties, slurry body is even.
D level: stability is worst, density distribution is obviously uneven, and producing hard-caked sediment cannot regenerate.
As seen from the above-described embodiment, and for above technique effect, the proportioning of embodiment two and processing parameter, it may also be useful to effect is best, is obviously better than other embodiment, is the best.
What finally illustrate is, above embodiment is only in order to illustrate the technical scheme of this patent and unrestricted, although this patent being described in detail with reference to better embodiment, it will be understood by those within the art that, the technical scheme of this patent can be modified or equivalent replace (such as adding proportion have that adjust, industrial waste oil product source may be other mechanical means sources a little etc. such as civilian machinery), and not departing from objective and the scope of technical solution of the present invention, it all should be encompassed in the middle of the right of the present invention.
