Abstract
The invention discloses a process method for recycling a disproportionated rosin waste liquid. The steam method comprises the processes of dissolution, stewing, clarification, residue filter pressing, distillation and packaging. A plate-type filter press and a centrifugal oil-water separator are employed in the residue filter pressing. The invention has the advantages that residual waste liquid as a raw material from a rosin factory is processed and recycled by the above disproportionated rosin processing method; the method has yield of effective components reaches more than 98%, and can rapidly separate impurities, and recover rosin and turpentine. The filter pressing method can be used for sewage treatment in rosin plant, recycles and utilizes production water, and achieves zero discharge of sewage.
Description
Technical field

Background technology
Waste rosin liquid now, the method all taking to discard after extracting Colophonium, make resource suffer significant wastage；And Colophonium
Waste liquid is poured in streams, also therefore can recycle environment to waste rosin liquid, be that rosin production enterprise must not
The problem anxious to be resolved not faced.
Summary of the invention
The goal of the invention of the present invention is: for the deficiencies in the prior art, it is provided that a kind of disproportionated rosin devil liquor recovery Colophonium
Process.
The technical solution used in the present invention is:
The process of a kind of disproportionated rosin devil liquor recovery Colophonium, comprises the following steps:
(1) dissolve: by residue waste liquid, water, oxalic acid and Oleum Terebinthinae according to 600～700: 200～300: 1～the matter of 3: 400～600
Amount, than mixing, heating for dissolving in dissolving pan, obtains mixing fat liquid；
(2) stand: input in several standing pots through dissolving the mixing fat liquid obtained, stand 40～60 minutes, discharge major part
Moisture content and slag thing, obtain standing fat liquid；
(3) filter: the fat liquid obtained in step (2) filter screen of 80～150 mesh is filtered to get filtrate;
(4) clarification: stand fat liquid and enter the clarifying kettle group of series connection, clarification 6-8 hour, discharge moisture content and slag thing, isolate dry
Clean fat liquid；
(5) filter pressing separates: stand and clarify moisture content and slag thing, filtrate separated device separation water that operation is discharged with Filter Press
Part and fat liquid, moisture content returns dissolution process, and fat liquid delivers to boiler operation；
(6) distillation fat liquid: the clean fat liquid obtained after clarified, delivers to distillation in boiler, reclaims Oleum Terebinthinae；
Preferably technical scheme is: the process of above-mentioned disproportionated rosin devil liquor recovery Colophonium, uses in filter pressing separation circuit
Plate and frame type filter-press.
Further preferably scheme is: the process of appeal disproportionated rosin devil liquor recovery Colophonium, described plate and frame type filter-press,
Including frame, frame is provided with filter mechanism, and described filter mechanism includes filter frame, filter screen and the filter plate being spaced, institute
The filter plate stating plate and frame type filter-press is that sandwich-type double-sided porous metals web plate is made.
The present invention, the process of above-mentioned disproportionated rosin devil liquor recovery Colophonium, use centrifugal in filter pressing separation circuit
Oil water separator.
Further preferably scheme is: the process of appeal disproportionated rosin devil liquor recovery Colophonium, described centrifugal profit divides
From device, it is characterised in that: include pallet, stem stem, urceolus, case and the rotor that in urceolus internal phase, stem stem can be rotated, rotor
It is placed on stem stem, is placed between stem stem and urceolus;Rotor is constituted by cylinder and from the pillar filter that cylinder body bottom is protruding,
The cylinder body bottom periphery of rotor is provided with nozzle；Described nozzle becomes 90 degree of tangential directions to arrange with the barrel of rotor.
Further preferably scheme is: the process of appeal disproportionated rosin devil liquor recovery Colophonium, rotor is provided with rotor drum
Lid, pillar filter is provided with strainer cover.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
1. this invention utilizes plate and frame type filter-press filtration to separate with centrifugal oil-water separator, and moisture content and fat hydraulic pressure are leached；
All recycle, not externally discharged waste water, decrease the consumption of water and oxalic acid simultaneously, saved cost；The most centrifugal oil-water separation
Device uses entirely mechanical mode to be effectively separated profit, it is not necessary to add any chemical agent, simple in construction, operation side
Just, discharge is reduced；3. centrifugal oil-water separator hydraulic oil aqueous mixtures impinges upon generation counteracting force on urceolus, makes rotor high
Speed rotates, thus by the most broken for oil water mixture droplet, makes oil water mixture be become suspension by emulsifying shape, then at weight
Under power effect, profit precipitate and separate voluntarily, whole device need not input by any power, energy-saving and emission-reduction；4. economizing on resources, technique walks
Rapid simple, process low cost, the response rate is high.
Detailed description of the invention
Hereinafter the detailed description of the invention of the present invention is further described.
Example 1:
The process of a kind of disproportionated rosin devil liquor recovery Colophonium, step is: (1) dissolves: at band sieve plate with there is slag-drip opening and interior
The dissolving pan of gallbladder formula defecator is carried out.First add water 0.2 ton, add Oleum Terebinthinae 0.4 ton, oxalic acid 0.001 ton, so
After 0.6 ton of disproportionated rosin waste liquid is loaded dissolving pan, temperature rises to 80 DEG C, is then shut off working steam, keeps 5 minutes.Open
Discharging opening gate valve, sends mixing fat liquid into standing pot.(2) stand: the mixing fat liquid input that dissolution process obtains stands in pot,
After standing 40 minutes, open drain valve, discharge most of moisture slag thing, obtain standing fat liquid.(3) fat liquid will be stood to pass through
The drainage screen of 80 mesh, it is thus achieved that filtrate.(4) clarification: the filtrate being filtrated to get is sent into the clarifying kettle group of series connection, and to clarify 6 little
Time, timing is discharged moisture and slag thing, is isolated clean fat liquid.Clean fat liquid after clarification sends into measuring tank, prepares by quantitatively sending
Enter distillation process.(5) separation is filtered: each waste residue standing pot and clarifying kettle discharge gathers in storage tank, then input binder tank
Carry out binder operation, the steps include: to be first shut off inlet valve, exhaust-valve, open outlet valve, then delay and drive air valve into, will by tank
Material press-in pressure filter inner filtration, filtrate is from flowing to oil water separator, and the filtrate after oil-water separation sends dissolution process back to, works as binder
Pressure tank is stable can shut down slag tap when 0.03MPa no longer declines, and fuel useed as by filter cake.(6) distillation fat liquid: quantitatively (
Capacity 80%) clean fat liquid is loaded one-level boiler, slowly open and close vapour and working steam, be heated to 150 DEG C and turn off working steam, fat
Liquid input secondary distillation pot, one-level boiler feeds again.Fat liquid continues to add thermal distillation at secondary distillation pot, and kettle temperature reaches
190 DEG C, close working steam when Oleum Terebinthinae reclaims complete, close vapour stopping distillation procedure, open and put fragrant valve discharging barrelling, be after cooling
Colophonium finished product.
