Description
Technical field
The present invention relates to Technologies of Coke Plant Wastewater Treatment field, and in particular to a kind of auxiliary demulsifying agent and preparation method thereof and uses
On the way more particularly to a kind of coal chemical industrial waste water extracting and emulsifying prevention and control auxiliary agent and its preparation method and application.
Background technique
Extraction is presently the most mature one of the method for removing phenols in coking wastewater except phenol, big by domestic and international enterprise
In the process for treating waste liquor that sizable application is formed during the biggish High T-emperature Carbonization of yield and gas purification etc..But it is extracting
In the process, cenotype, i.e. Middle emulsion layer, also referred to as third phase are often generated between organic phase and water phase.This is mutually oil-in-water or oil
Water-in type coarse emulsion, in addition to this also extraction reaction process in by other impurities and power effect, formed it is a kind of complexity
Heterogeneous emulsion.The emulsion is stable in the presence of in extraction system by being influenced the effects of solid particle, inorganic salts in waste water,
It is difficult to eliminate.Deal with the principal mode that will become extractant loss improperly.
Industrially the more solution of application is to extract Middle emulsion layer at present, then demulsification recycling extractant.By
It is only broken using only the block polyether class of traditional ethylene oxide propylene oxide in the complexity and stability of Middle emulsion layer composition
Emulsion, water separation capability are extremely limited.Cause a large amount of extractants that cannot recycle, increased considerably Treatment of Coking Effluent at
This.On the other hand, unrecovered extractant is discharged into environment with raffinate, and natural stream networks is caused to pollute.And the extraction in water system
Agent is not easy by biological decomposition, and the post-processing approach such as activated sludge are difficult to remove it.Not recoverable extractant, which will increase, to be discharged
Water COD value, promotes the growth etc. of mould, or even endangers aquatic organism and the health of the mankind.
At present about the correlative study of demulsifier.CN104817150A discloses a kind of compound demulsifying flocculant,
Consisting of: the cationic demulsifier of 60wt%-80wt%；The polydimethyl diallyl ammonium chloride of 10wt%-20wt%；
The aluminium polychloride of 5wt%-10wt%；And the polymethylacrylic acid of 5wt%-10wt%, which can
To be completed at the same time demulsification, flocculation, oil removing, the work for purifying sewage.It is former that CN104818048A discloses a kind of composite type high temperature resistant
Oily demulsifier includes: 15-25 parts of cocoanut fatty acid diethanolamide, C12-20 alkyl glycosides 5- in parts by weight
10 parts, 2-8 parts of hoveniae semoveniae semen, 0.1-0.2 parts of yacon, 0.3-0.9 parts of the achene of Siberian cocklebur, 0.5-3 parts of sodium metasilicate, dimethyl -2 2,6-,
5-9 parts of 6- octadiene -8- alcohol, 0.6-1.5 parts of citric acid, 0.5-1.8 parts of gelatin, 2-6 parts of ethylene glycol, 90-120 parts of water, this is broken
Emulsion can make the water in crude oil by aggregation sedimentation, and water rem oval may be up to 95-99%；In addition, can also effectively remove in crude oil
Dissolved with the water of salt, salt rejection rate is up to 90-95%.It is embedding that CN104673358A discloses a kind of alcohols two with laboratory synthesis
Section, three block, multi-block polyether type demulsifier cooperate with the research of compounding with conventional anion type demulsifier, by the demulsification after compounding
Agent carries out crude oil demulsification experiment, and by data, it can be concluded that, compared to traditional demulsifier, the compounding row which is related to is broken
Emulsion compared with traditional demulsifier, is greatly improved on rate of water loss and dehydration rate, can improve breaking emulsion and dewatering rate
15%~30%, effect is better.
However, an important feature due to above-mentioned demulsifier is that specificity is strong.Such as a certain factory's coking wastewater is generated
The effective demulsifier of Middle emulsion layer system, the Middle emulsion layer system generated to the coking wastewater in other factory sources may not
Effectively.
It is therefore desirable to design a kind of compound auxiliary agent for coking wastewater Middle emulsion layer characteristic, traditional demulsifier is made up
Demulsification is not good enough, the too strong disadvantage of specificity, solves the problems, such as that the useless extractant of coking is seriously lost because of emulsification.
Summary of the invention
In view of the deficiencies of the prior art, it the present invention provides a kind of auxiliary demulsifying agent and its preparation method and application, especially mentions
