Technical field
The invention belongs to plating waste gas pollution control and treatment technical field, particularly relate to a kind of plating Cu or plating Ni groove gas recovery system.
Background technology
Plating (Electroplating) is exactly the process utilizing electrolysis principle to plate other metal or alloy of skim on the surface of metal or other material, the surface attachment layer of metal film of metal or other material can be made by plating, thus play and prevent burning (as corrosion), improve the effects such as wear resistance, electroconductibility, reflective, erosion resistance and having improved aesthetic appearance.Therefore, electroplating technology widespread use in machinery, five metals and electrical equipment etc. process of producing product.Plating is the indispensable industry of the national economic development, and plating pollution on the environment problem can not be ignored, and the plating disposal of three wastes is extremely urgent.
Plating is carried out in plating tank, it is different and different that the composition of the electroplate liquid in plating tank looks coating, but all containing the main salt providing metal ion, in the main salt of energy complexing, metal ion forms the complexing agent of complex compound, for the buffer reagent of stabilizing solution potential of hydrogen, anode activation agent and special additive (as brightening agent, grain-refining agent, leveling agent, wetting agent, stress relieving agent and inhibiting fog agent etc.).Electroplating process be the metal ion in plating solution under the effect of external electric field, be reduced into atoms metal through electrode reaction, and in the process of negative electrode enterprising row metal deposition.Therefore, this is a metal electrodeposition process comprising the steps such as mass transfer in liquid phase, electrochemical reaction and electrocrystallization.
Electroplating process carries out at a certain temperature, and plating tank can produce waste gas.As plated Cu or plating Ni, if waste gas of leaving is discharged, both affecting workshop condition, and affecting operator's labor safety and healthy, also can pollute air, against environmental requirement.The improvement of current electroplating industry to waste gas there is no good measure, usually only above plating tank, arranges gas sampling cover, is then sent to recovery tower and reclaims and the rear discharge of process further.Tradition gas collecting mode is divided into two large classes by cover implication stream flow pattern, i.e. air suction type gas skirt and Blowing and sucking gas trap hood, gap is had with cell body top in this kind of gas skirt use procedure, gas, mist can spill from gap, treating processes efficiency is low, cost is high, and the pollution problem of waste gas to workshop condition and air can not get basic solution.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, propose a kind of plating Cu or plating Ni groove gas recovery system, fundamentally solve plating Cu or plate Ni waste gas to the pollution problem of environment, plating solution evaporation is reduced in technological process, processing efficiency is high, recycle mixed solution, reduces running cost.
The technical scheme that technical solution problem of the present invention is taked is, a kind of plating Cu or plating Ni groove gas recovery system, comprise plating Cu or plating Ni groove, blower fan, recovery tower, accumulator tank and pure water groove, under described plating Cu or plating Ni groove notch, side, 10 ~ 15cm place is provided with gas collection and exports; Be provided with filtering layer in the middle part of described recovery tower, top is provided with exhaust-duct, and described pure water groove is connected with recovery tower top through pure water pipeline; Described plating Cu or plating Ni groove, blower fan, recovery tower and accumulator tank, consist of the recycle system reclaiming, utilize collecting pipe, recovery channel, feedback pipeline and reuse pipeline.
As preferably, the described recycle system comprises: described plating Cu or the gas collection outlet of plating Ni groove side are communicated with recovery tower bottom through collecting pipe and are provided with blower fan on described collecting pipe, bottom described recovery tower, liquid outlet is communicated with accumulator tank through recovery channel, described accumulator tank is communicated with recovery tower top through feedback pipeline, and described accumulator tank is through reuse pipeline communication plating Cu or plating Ni groove.
Described plating Cu or plating Ni groove and pure water groove be respectively equipped with liquidometer A and liquidometer B.
Described pure water pipeline is provided with pump A.
Described feedback pipeline is provided with pump B.
