Abstract
The utility model belongs to the technical field of electroplating waste water treatment, relates to the structure improvement of an electrolytic device for electroplating waste water treatment, especially relates to an electroplating waste water electrolytic tank with hydraulic cyclone separator, which is characterized in that an electrolyte outlet in the electrolytic tank is connected with a liquid inlet pipeline of the hydraulic cyclone separator by a pump, and the hydraulic cyclone separator is communicated with an electrolytic tank pipeline by a return pipe to form a liquid loop. The lower part of the hydraulic cyclone separator is detachably connected with a heavy metal collecting pipeline by a valve. The utility model has the following positive effects: the metal particles separated out from the electrolyte during electrolytic treatment process is separated by hydraulic cyclone centrifugation, the sediment is gathered in the heavy metal collector by the valve, the electrolyte is exhausted by the return pipe after separating the heavy metal particles, then returns back into the electrolytic tank to continuously electrolyze, thereby facilitating reducing the cyanide in electroplating waste liquid or waste water, recovering noble and heavy metals, rapidly and effectively achieving the emission standard meeting the environmental protection requirement.
Description
Technical field
The utility model belongs to the electroplating waste water treatment technology field, relates to the texture improvement of the electrolyzer that electroplating wastewater processing uses, and relates in particular to a kind of electroplating wastewater electrolyzer with centrifuge separator.
Background technology
The waste water composition that produces in the electroplating industry production process, content is relevant with electroplating technology with electroplating, usually contain precious metal ions such as heavy metal ion such as copper, nickel and some gold and silver in the electroplating wastewater, also contain the prussiate of severe toxicity etc. sometimes, or contain the organic composition (COD) of decomposition in distress.Now for the electroplating wastewater that contains prussiate, metal ion and organic composition, the emission standard of the compliance with environmental protection requirements of carrying out with electrolyzer often reaching satisfied when electrolytic process is handled, after also the waste water through electrolysis treatment must being delivered directly to follow-up equipment and cyanide oxidation being become innoxious substances such as carbonic acid gas and nitrogen, just can reach the emission standard of prussiate with pharmaceutical chemicalss such as clorox; Heavy metal of separating out during for electrolysis treatment and precious metal ion generally also adopt the method for chemical precipitation, make these objectionable constituent isolate water body, reach associated metal ionic emission standard.But the metal recovery after chemical precipitation is worth and reduces.
The utility model content
The purpose of this utility model is: the electroplating wastewater electrolyzer that a kind of band centrifuge separator simple in structure, easy to use is provided, help to reduce effectively, fast the prussiate in electroplating effluent, the waste water, reclaim expensive, heavy metal, to reach the emission standard of compliance with environmental protection requirements.
For achieving the above object, the technical scheme that adopts is: a kind of electroplating wastewater electrolyzer with hydrocyclone, comprise electrolyzer and place the interior electrode of described electrolyzer, it is characterized in that: place the electrolyte outlet of described bottom of electrolytic tank to be connected with the liquid-inlet pipeline of hydrocyclone by pump, described hydrocyclone communicates with described electrolyzer by return line, constitutes fluid loop.
Described hydrocyclone below is connected with heavy metal collector pipeline by valve.
Described valve is threaded with described heavy metal collector detached type.
Positively effect of the present utility model is: the metal particle that electrolysis treatment process electrolytic solution is separated out is through the hydrocyclone centrifugation, precipitate, accumulate in the heavy metal collector by valve, electrolytic solution behind the separating metal particulate is discharged by return line, return electrolyzer again and continue electrolysis, help to reduce the prussiate in electroplating effluent, the waste water, reclaim expensive, heavy metal, fast and effeciently reach the emission standard of compliance with environmental protection requirements.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Fig. 1 is the utility model structural representation.
Among the figure, the 1-electrolyzer; The 2-pump; The 3-hydrocyclone; The 4-return line; The 5-valve; 6-heavy metal collector.
Embodiment
Fig. 1 is the utility model structural representation.By as seen shown in Figure 1, a kind of electroplating wastewater electrolyzer with hydrocyclone, comprise electrolyzer 1 and place the interior electrode of described electrolyzer, it is characterized in that: place the electrolyte outlet of described electrolyzer 1 bottom to be connected with the liquid-inlet pipeline of hydrocyclone 3 by pump 2, described hydrocyclone 3 communicates with described electrolyzer 1 by return line 4, constitutes fluid loop.
Described hydrocyclone 3 belows are connected with heavy metal collector 6 pipelines by valve 5.
Described valve 5 is threaded with described heavy metal collector 6 dismountable types.
During use, commercially available hydrocyclone 3 diameters between 100 to 300 millimeters, can be fixed on arbitrarily on the cell wall of electrolyzer usually.Adopt corrosion-resistant efficiently (platinum group) electrode in the electrolyzer 1, by controlling electrolytic time and intensity, cyanide ion is decomposed below the 0.10ppm, with water pump 2 electrolysis wastewater that is mixed with heavy metal particle in the electrolyzer 1 is tangentially pumped into along hydrocyclone 3 imports then, owing to retrained by hydrocyclone 3 limit walls, tangential motion becomes and rotatablely moves, produce the eddy current of high speed rotating, and then produce very big centrifugal acceleration, metal particle sedimentation under the effect of centrifugal force and gravity, be enriched in heavy metal collector 6 bottoms by valve 5; Shut-off valve 5 can be screwed integral body and be shirked heavy metal collector 6, regularly reclaims the noble metal of enrichment; Electrolysis wastewater after hydrocyclone 3 rotating centrifugals separate turns back to electrolyzer 1 circulation through the return line 4 of hydrocyclone 3 and continues electrolysis treatment, helps electrolysis wastewater fast and effeciently to reach the emission standard of compliance with environmental protection requirements.
