Copolymer resins waste water concentrating recovery device
Technical field
The utility model relates to a kind of centrifuge waste water and concentrates recovery system, specifically a kind of copolymer resins waste water concentrating recovery device that is used for vinylchlorid and vinyl acetate between to for plastic copolymer resins.
Background technology
In the prior art, vinylchlorid and the wastewater produced processing of vinyl acetate between to for plastic copolymer resins, usually adopt following method: in waste water, add special-purpose precipitation agent, solid in the emulsion is separated with liquid, get supernatant liquid again through biochemical treatment, clear liquor after the processing directly discharges, and solid sediment is then transported outward and entrusted other processed in units.
The defective of this processing mode is: waste water does not only utilize, and the transfer of the objectionable impurities in the solid, liquid, and unfavorable to environment, processing cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can reclaim useful matter in the waste water, can avoid the copolymer resins waste water concentrating recovery device of contaminate environment simultaneously.
The technical scheme that provides according to the utility model, described copolymer resins waste water concentrating recovery device, comprise putamina, it is characterized in that: be to see through the chamber in the described putamina, see through and in the chamber hundreds of to tens thousand of external diameters to be set the hollow tubular tubular fibre that is 1~2mm, described tubular fibre can only be through the small molecules particle and macromolecular particle only thoroughly; Described putamina is a cylindrical body, closes up in two ends, and first end is the waste water import, and second end is a concentrated solution outlet, is provided with the outlet of first permeate water in the side near first end, is provided with the outlet of second permeate water in the side near second end; Between waste water import and the outlet of first permeate water, be provided with left clapboard, between concentrated solution outlet and the outlet of second permeate water, be provided with right clapboard.
Described small molecules particle is the material of thousands of~tens thousand of molecular weight, and described macromolecular particle is the material of hundreds thousand of~millions of molecular weight.
The wastewater flow of described waste water import is 400~500L/m
2H; Pressure 0.07~0.15Mpa; The permeate water flow is 18~20L/m
2H; Wastewater pH is 2.5~3.0.
Operation scheme of the present utility model is successional, and technical process is short; The limit reuse is separated in waste water access to plant back, and waste water is all reclaimed, and has both saved production cost, has realized zero release again, has really reached green production.And equipment is few, and volume is little, and floor space is little; Fully automatic operation, disposable water delivery, power consumption is economized, and overall running cost is low, and processing costs is low.

Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
Shown in Fig. 1~3: copolymer resins waste water concentrating recovery device comprises waste water import 1, end socket 2, left clapboard 3, first permeate water outlet 4, putamina 5, sees through chamber 6, tubular fibre 7, right clapboard 8, second permeate water outlet 9, concentrated solution outlet 10, macromolecular particle 11, small molecules particle 12 etc.
The utility model comprises putamina 5, be to see through chamber 6 in the described putamina 5, is the hollow tubular tubular fibre 7 of 1~2mm through being provided with hundreds of in the chamber 6 to tens thousand of external diameters, and described tubular fibre can only see through thousands of~tens thousand of molecular weight and the material of saturating only hundreds thousand of~millions of molecular weight; Described putamina 5 is a cylindrical body, close up in two ends, first end is that waste water import 1, the second end is a concentrated solution outlet 10, be provided with first permeate water outlet 4 in side, be provided with second permeate water outlet 9 in side near concentrated solution outlet 10 1 ends near waste water import 1 one ends; Between waste water import 1 and first permeate water outlet 4, be provided with left clapboard 3, between concentrated solution outlet 10 and second permeate water outlet 9, be provided with right clapboard 8.
After the adjusting waste water ph is 2.5~3.0, enter again in the putamina 5; When waste water flows into putamina 5 from waste water import 1 end, and enter in the tubular fibre 7, small molecules particle 12 sees through tubular fibre, flows out through lateral first permeate water outlet, 4 and second permeate water outlet 9, and macromolecular particle 11 flows out from the concentrated solution outlet 10 of second end.Therefore, waste water is by behind the tubular fibre 7, and small molecules particle 12 is separated with macromolecular particle 11, concentrates the purpose that reclaims thereby reach waste water.
Described waste water import 1 adopts big flow to advance waste water, and wastewater flow is 400~500L/m
2H; Low pressure operation operation, pressure 0.07~0.15MPa; The permeate water flow is 18~20L/m
2H.
The utility model adopts the ultra-filtration membrane isolation technique, and waste water can be separated into two parts: a part is a concentrated solution, i.e. suspension liquid body after concentrated, and this suspension liquid body can be used as raw material and is back on the production line; Another part is to see through liquid, and the thinner that can be used as pure raw material is back on the production line.The utility model can make the waste water fully recovering, realizes the waste water treatment zero release, reaches green production.
