Description
Technical field
The present invention relates to the distilation field of debirs, the pre- place before especially a kind of rapid boiling debirs distillation
Reason method.
Background technology
Distillation is a kind of simple and efficient material method of purification, and the principle distilled is the liquid phase medium that will be distilled,
So that its certain media is gasified under the action of heated, coolant liquid will be carried out by thermal evaporation pure medium using condenser
Change and collects；But it is difficult in the rapid boiling debirs of distillation, because unstable containing centainly distilling in rapid boiling debirs
The structure of matter, heat the during of distilling be very easy to occur pinking, suddenly exhaust, boiling, foam constantly generate suddenly
And phenomena such as accumulating rise, therefore when distilling this substance, necessarily show as following drawbacks：
1. evaporating air pressure fluctuating cataclysm, distillation work is set to can not achieve steady progress, in extreme circumstances potential eruption or explosion
Risk.
2. being very easy to generate a large amount of foam and constantly accumulation going up, thus the foam is very easy to by discharge vaporization mouth
Discharge, causes distilation to fail.
3. relatively low by component degree of purity collected by distillation.
Under 4. evaporation efficiency is very low.
Herein that debirs as characterized above are qualitative to boil debirs suddenly, the rapid debirs that boil include：It is useless to roll
Liquefaction, steel rolling sludge, waste emulsified mixture, useless lubricating grease etc..
Herein by the mineral type automobile engine oil scrapped it is qualitative be debirs, it is fixed that the distillation of waste performance is considered as
Property object of reference.
The pH value for boiling debirs suddenly will be made to be intended to acid substance herein, be defined as acidic materials.
The pH value for boiling debirs suddenly will be made to be intended to the substance of alkalinity herein, be defined as alkaline matter.
Invention content
The purpose of the present invention is intended to overcome the drawback of background technology, and provides a kind of technological means neutralized by acidolysis,
The structure of matter for decomposing destructive distillation unstable material boils the preprocess method before debirs distillation to which realization is rapid, is
The distilation of rapid boiling debirs provides advantage.
The technical solution adopted by the present invention is：
A kind of rapid preprocess method boiled before debirs distillation, its step are as follows：
Hydrolysis step：Debirs will be boiled suddenly to mix into Mobile state with acidic materials, be participated in by the mixing of acidic materials, be made it
The mixture pH value of formation reaches 4 or less；
Neutralization procedure：Mixture caused by hydrolysis step is mixed with alkaline matter into Mobile state, the mixed of alkaline matter is passed through
It closes and participates in, the mixture pH value formed it into reaches 7 or more.
Using above-mentioned technical proposal compared with prior art, the present invention advantageous effect is：
Debirs can be made to boil suddenly under the stable state of air pressure fluctuating, receive the distillation working condition of heating gasification；
In the heated operating mode of distillation, the phenomenon that constantly being generated without extraordinary foam and accumulate rise；Thus it can not only be greatly improved
The degree of purity of fraction can also greatly improve the working efficiency of rapid boiling debirs distilation.
Further, preferred embodiment of the present invention is：
The acidic materials are sulfuric acid.
The alkaline matter is pulverized limestone.
The acidic materials are acidic wastes.
The alkaline matter is alkaline waste.
The acidic materials are acid sludges caused by oil plant acid treating link.
The rapid boiling debirs are that waste rolling oil, steel rolling sludge, waste emulsified mixture, useless lubricating grease are one kind of or a variety of
Mixture.
Finally formed mixture pH value is 3 or less in the hydrolysis step.
Finally formed mixture pH value is 2 or less in the hydrolysis step.
Finally formed mixture pH value is 1 or less in the hydrolysis step.
Specific implementation mode
The present invention is described in detail with reference to embodiments.
Embodiment 1：
By the material of doubtful rapid boiling debirs, it is packed within experiment cucurbit and carries out distillation inspection；If having rapid boiling has
Machine waste features, it is determined that be rapid boiling debirs；If not having rapid boiling debirs feature, be not boil suddenly it is organic
Waste is not required to implement pretreatment as described herein.
In the present embodiment, the rapid debirs that boil are the waste emulsified mixtures that metal cutting industry is scrapped, and acidic materials are sulfuric acid,
Alkaline matter is pulverized limestone.
The waste emulsified mixture of 1000kg is put within the container of 2m3, to waste emulsified mixture within slow dynamic be added sulfuric acid, make
It is chemically reacted under the operating mode of relatively uniform mixing, and certain heat will be generated during reaction, in heat liter
Under the effect of temperature, reaction process will be accelerated.
At the end of above-mentioned intense reaction process is basic, the pH value of said mixture is detected, if pH value is more than 4,
It also needs to continue dynamic mixing into it and sulfuric acid is added, and provide certain chemical time.
At the end of above-mentioned intense reaction process is basic, the pH value of said mixture is detected, if pH value is less than 4, i.e.,
The addition work of sulfuric acid can be terminated, also needs to provide certain chemical time for above-mentioned chemical reaction when necessary.
The length of chemical time depends primarily on two kinds of factors, and factor one is that have to boil the bright of debirs feature suddenly
Aobvious degree, factor is second is that acidolysis depth（PH value after acidolysis is lower, and acidolysis depth is then deeper）The depth；Have boil suddenly it is organic
Waste features are more apparent, acidolysis depth is more shallow, and required chemical time is longer.
In order to understand pretreatment whether achieve the desired purpose, it is also necessary in above-mentioned acidolysis material, take out part sample into
Row neutralizes and the mixture pH value formed it into reaches PH7 or more, and then pretreatment sample is packed within experiment cucurbit
Carry out distillation inspection；Do not have rapid boiling debirs feature, then explanation has reached expected purpose；Still has rapid boiling organic waste
Object feature, it is also necessary to continue to extend chemical time or continue to deepen acidolysis depth.
In the present embodiment, why acidolysis depth is set as pH value 4 hereinafter, being because of following two reasons；If will
Acidolysis depth formulated it is shallow, then pretreated working efficiency is too low；It is not only excessive if the formulation of acidolysis depth is too deep
The acid physical resources of consumption, also inevitable excessive consumption alkaline matter resource.
" dynamic mix " of this paper can respectively by the mixing that pneumatically mixes, surges, motor-driven mixing or hand mix its
In a kind of hybrid mode or a variety of hybrid modes realize complete.
Hydrolysis step as described herein is mainly used for decomposing the unstable structure of matter of destructive distillation；It is as described herein
Neutralization procedure is mainly used for eliminating the acidic character after acidolysis, avoids associated equipment by sour corrosion, reduces product sulphur and contain
Amount improves product quality.
After implementing pretreated hydrolysis step, static conditions are provided if it is the larger acidolysis mixture of water content,
Part organic wastewater can also be separated outward, then can by it is other it is neutralized after material carry out distilation again.
Distillation described herein includes air-distillation, vacuum distillation and high pressure distillation.
