Abstract
The invention discloses a kind of methods with cold rolling waste emulsified mixture coal slurry flotation, the medicament of coal slurry flotation are done collecting agent using the waste emulsified mixture generated in cold-rolling process, sec-octyl alcohol does foaming agent, for coal slime flotation operation.Waste emulsified mixture is directly used in coal slurry flotation by the present invention, can make the best use of everything, and coal separation is to recycle with water, does not need to individually handle, can effective diesel oil substitute coal slurry flotation.
Description
Technical field
The present invention relates to the methods with cold rolling waste emulsified mixture coal slurry flotation.
Background technology
The Industry Waste grease that iron and steel enterprise is discharged in process of production（Such as：Cold rolling waste emulsified mixture）Wait intractabilities compared with
Greatly, most domestic enterprise is burns, fills or store up for a long time.To dispose the waste oil（Or emulsion）（It is hereinafter referred to as useless
Emulsion）, the processing equipment of emulsion need to be further invested, is demulsified, agglomerated using drug, floating upper separation, making main oil emulsion
It is removed in chemical demulsification slot, then through the electric floating, filtering of electrolysis, activated carbon adsorption, Emulsion waste water is made to obtain to purification.The equipment by
Supply unit, chemical demulsification slot, electrolysis unit, electric floating trough, filterability carbon column and water pump composition, investment cost is big, operation
It is of high cost.
Invention content
The purpose of the present invention is to provide a kind of method with cold rolling waste emulsified mixture coal slurry flotation, using waste emulsified mixture as floating
Medicament is selected to be directly used in coal slurry flotation, can be made the best use of everything, coal separation is to recycle with water, does not need to individually handle, can be effective
Diesel oil substitute coal slurry flotation.
The object of the present invention is achieved like this, a kind of method with cold rolling waste emulsified mixture coal slurry flotation, by coal slurry flotation
Medicament collecting agent is done using the waste emulsified mixture generated in cold-rolling process, sec-octyl alcohol does foaming agent, makees for coal slime flotation
Industry.
The method of the present invention first does laboratory small-scale test in use, by different coal slime classifications, establishes floatation concentration, medicament
Dosage, flotation time predict cleaned coal index, by the adjustment and matching of laboratory parameters, determine the technology of industrialized production
Then parameter is implemented in the industrial production.
Now with the waste emulsified mixture discharged in iron and steel enterprise's cold rolling mill production process respectively to tri- kinds of coal slimes of A1, A2, A3 into
For row float test：
Experiment is using 1 liter of flotation device of XFD types single-channel type；Floatation concentration 15%；Foaming agent, sec-octyl alcohol dosage 100g/ are with sec-octyl alcohol
t；Collecting agent, diesel oil dosage 1800g/t, waste emulsified mixture dosage 6250ml/t are with diesel oil, waste emulsified mixture；During with waste emulsified mixture,
Flotation time is 6 minutes, relatively more viscous due to acid fatty in waste liquid, therefore flotation time is slightly long compared with diesel oil（Use diesel oil
When, flotation 4 minutes）.Result of the test is as shown in table 1.
It is seen by 2 floatation clean coal index comparing result of table, does collecting agent with waste emulsified mixture, A1 floatation clean coal yields are higher, reach
To 91.08%, ash content index with diesel oil index also with being approached.A2, floatation clean coal index are close, and A3 cleans ash indexs are preferable, production
Rate is slightly lower.On the whole, coal separation collecting agent is done with waste emulsified mixture, effect is fairly obvious, can complete diesel oil substitute.
Specific embodiment
The medicament of coal slurry flotation is used what is generated in cold-rolling process by a kind of method with cold rolling waste emulsified mixture coal slurry flotation
Waste emulsified mixture does collecting agent, and sec-octyl alcohol does foaming agent, for coal slime flotation operation.
By taking the waste emulsified mixture that the cold rolling mill of certain iron and steel enterprise is discharged as an example, which discharges waste emulsified mixture amount as 300m3 every year.
Due to no upper liquid waste treating apparatus, this batch of waste liquid is stored up storehouse and is not utilized for a long time.And there is coal in each coal washery in enterprise periphery
Mud generates, and does collecting agent coal slurry flotation with cold rolling waste emulsified mixture, can not only waste emulsified mixture be enable to recycle again, and can
It reduces by 1/3rd diesel oil dosage, the production run cost of coal washery is greatly lowered, comply fully with national recycling economy hair
Exhibition policy, direct economic benefit and social benefit are very significantly.
For recycling 300m3 waste emulsified mixtures：
With 300m3 waste emulsified mixtures, 48000 tons of coal slimes can be handled, 8.64 tons of diesel oil dosage can be saved, direct economic benefit can be saved
Nearly 500,000 yuan.What is more important enables the dangerous waste that arranged or store up outside originally to recycle again, and forms new valency
Value has significant social benefit.
