Description
Technical field
The utility model relates to a kind of centrifuge waste water and handles reclaimer, specifically a kind of copolymer resins waste water treatment and reclamation device that is used for vinyl chloride and vinyl acetate copolymer resins.
Background technology
In the prior art, vinyl chloride and the wastewater produced processing of vinyl acetate copolymer resins, usually adopt following method: in waste water, add special-purpose precipitating reagent, solid in the emulsion is separated with liquid, get supernatant liquid again through biochemical treatment, clarified solution 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 harmful substance in the solid, liquid, and unfavorable to environment, processing cost is higher.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, provides a kind of and can reclaim utility in the waste water, can avoid the copolymer resins waste water treatment and reclamation device of contaminated environment simultaneously.
For achieving the above object, the technical solution of the utility model has provided a kind of copolymer resins waste water treatment and reclamation device, comprise the retracting device housing, it is characterized in that, the inside of described retracting device housing is for seeing through the chamber, at the described hollow tubular doughnut that is provided with some external diameter 1～2mm in the chamber that sees through, described doughnut can only see through little molecule particle and can not see through macromolecular particle; Described retracting device housing is a cylindrical body, be provided with the section that closes up at its two ends, interconnect by flange between described closing in section and the described cylindrical body, a described end that closes up section is made as the waste water import, the other end is made as concentrated solution outlet, be provided with the outlet of first permeate water in side, be provided with the outlet of second permeate water in side near the cylindrical body other end near cylindrical body one 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.
In the utility model, the material that described little molecule particle is thousands of～tens thousand of molecular weight, described macromolecular particle is the material of hundreds thousand of～millions of molecular weight.
In the utility model, the flow of waste water is 400～500L/m in the described waste water import
2.h; Pressure is 0.7～0.15Mpa; The permeate water flow is 18～20L/m
2.h.
In the utility model, the pH of waste water is 2.5～3.0.
Advantage of the present utility model and beneficial effect are: because the method for operation of this device is successional, technological 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-emission 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 disposal cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the B-B view among Fig. 1;
Fig. 3 is the enlarged drawing of A among Fig. 1.
Among the figure: 1, waste water import; 2, two ends; 3, left clapboard; 4, first permeate water outlet; 5, retracting device housing; 6, see through the chamber; 7, doughnut; 8, right clapboard; 9, second permeate water outlet; 10, concentrated solution outlet; 11, macromolecular particle; 12, little molecule particle; 13, closing in section; 14, flange.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Shown in Fig. 1～3, the utility model is a kind of copolymer resins waste water treatment and reclamation device, comprise retracting device housing 5, the inside of this retracting device housing 5 is for seeing through chamber 6, at the described hollow tubular doughnut 7 that is provided with some external diameter 1～2mm in the chamber 6 that sees through, described doughnut 7 can only see through little molecule particle 12 and can not see through macromolecular particle 11; Described retracting device housing 5 is a cylindrical body, be provided with the section 13 that closes up at its two ends 2, interconnect by flange 14 between described closing in section and the described cylindrical body, a described end that closes up section is made as waste water import 1, the other end is made as 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 the cylindrical body other end near cylindrical body one end; 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 in the utility model, the pH value of waste water being adjusted to 2.5～3.0, enter again in the retracting device housing 5; When waste water flows into Membrane recovery unit MRU housing 5 from waste water import 1 end, and enter in the doughnut 7, little molecule particle 12 sees through doughnut 7, flows out through first permeate water outlet, 4 and second permeate water outlet 9 of side, and macromolecular particle 11 flows out from the concentrated solution outlet 10 of the other end.Therefore, waste water is by behind the doughnut 7, and little molecule particle 12 is separated with macromolecular particle 11, concentrates the purpose that reclaims thereby reach waste water.
