Abstract
A device used in regeneration and recycle of electroplating washing water relates to a filtering and separation method by adopting microporous membrane. A washing groove, a circulating pump and the microporous membrane components are connected together through a pipe so as to form a closed circulating filtering system and to wash away suspended matter, heavy metal and colloid, etc. in the water, therefore, clear washing water is obtained. The filtration opening diameter of the microporous membrane or ultrafiltration membrane adopted is 0.1 to 10 microns, the material used is organic or inorganic material, the operating pressure is 0.2 to 1.0 MPa and the operation temperature is 5 to 90 DEG C. The utility model is widely applicable to electroplating, chemical and environmental protection industries.
Description
Technical field
The utility model relates to a kind of filter separation method, particularly a kind of filter separation method that adopts microporous membrane.
Background technology
Relate to the Electroplating Production operation of industries such as automobile, metal processing, be provided with the multiple tracks washing bath, be rinsed totally with the electroplate liquid that guarantees product surface.Traditional electroplating industry, the water of washing bath all are the direct current dischargings, have following shortcoming:
1, the water direct current of washing bath discharging causes the great amount of water resources waste;
2, owing to contain heavy metals such as nickel, copper, mercury, chromium in the washing water, the water direct current discharging of washing bath can cause serious environmental to pollute;
3, containing heavy metals such as nickel, copper, mercury, chromium in the washing water all is to be worth very high resource, and the water direct current discharging of washing bath is unfavorable for the recovery of heavy metal resources.
Summary of the invention
In order to overcome the shortcoming that the water resource waste, the environmental pollution that exist in the existing production system are serious, be unfavorable for the resource recovery, the utility model provides a kind of filter method that utilizes microporous membrane, this filter method not only can be saved great lot of water resources, and the reduction environmental pollution, further concentrating to reclaim and create conditions for heavy metal resources.
The technical scheme that its technical problem that solves the utility model adopts is: be formed by combining by washing bath, recycle pump, microporous membrane assembly, pipeline in system design, by pipeline washing bath, recycle pump, microporous membrane assembly are connected, constitute the filtering system of a closed cycle, entering and leach continuously of washing water carried out.Washing water in washing bath is squeezed into the microporous membrane assembly by recycle pump with certain pressure, and filtrate is directly got back in the washing bath, and whole filtering separation process is carried out continuously, and finishes under totally enclosed environment.
Plating of the present utility model washing water reuse reclamation set comprises the membrane filtration system that adopts microporous membrane or ultra-filtration membrane, in order to remove suspended substance in the washing water, heavy metal, colloid etc., obtains clarifying washing water.The microporous membrane that the micro-pore-film filtration system adopts or the pore size filter of ultra-filtration membrane are 0.1～10 micron, and material is the organic or inorganic material, and working pressure is 0.2～1.0 MPa, and service temperature is 5～90 ℃.
The beneficial effects of the utility model are, realized the separation method regeneration plating washing water of micro-pore-film filtration, and in system design, realize integrated and modularization, conserve water resource significantly improves the quality of plated item, reduces environmental pollution, create the condition that heavy metal resources reclaims, occupation area of equipment is little, and the operation convenient management can be widely used in plating, chemical industry, environmental protection industry (epi).
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a schema of electroplating first embodiment of washing water reuse reclamation set.
1. advance pipe at night, 2. washing bath, 3. recycle pump, 4. microporous membrane assembly, 5. blow-off pipe, 6. return line, 7. backwash tube in the accompanying drawing.
Embodiment
In the embodiment shown in the figures, electroplating washing water reuse reclamation set is combined by liquid-inlet pipe (1), washing bath (2), recycle pump (3), membrane module (4), blow-off pipe (5), return line (6), backwash tube (7).Implement the utility model, washing water enters washing bath (2) by liquid-inlet pipe (1), squeeze into microporous membrane assembly (4) by recycle pump (3) then, be back to washing bath (2) through the filtrate behind the micro-pore-film filtration through return line (6), when carrying out back flushing, pressurized air and wash-down water enter microporous membrane assembly (4) through backwash tube (7), and the back flushing waste liquid drains into sewage disposal workshop section by blow-off pipe (5), back flushing is regularly carried out in system's non-stop run.
Claims (1)
1. electroplate washing water reuse reclamation set for one kind, it is characterized in that adopting the membrane filtration system of microporous membrane or ultra-filtration membrane, the pore size filter that is shaped as of microporous membrane or ultra-filtration membrane is 0.1～10 micron a pipe, material is the organic or inorganic material, the structural attitude of electroplating washing water reuse reclamation set is by pipeline washing bath, recycle pump, microporous membrane assembly to be connected, and constitutes a cyclic closed cycle filtering system.
