Exhibition scheme.
Background technology
Electro-deposition techniques refer to that simple metal ion or complex ion pass through electrochemical method in solid（Conductor or semiconductor）
Metallic atom is reduced on surface and is attached to electrode surface, so that the process of a metal deposition layer is obtained, it is anti-in various electro-deposition
Ying Zhong, no matter what type of electrolyte solution, exoelectrical reaction of its zwitterion on anodic-cathodic be in compliance with the molten of ion
Liquid deposition potential order and electrochemical equivalent, after leading to direct current on cathode-anode plate, the zwitterion in electrolyte solution is in electric field
The solution of polar board surface is arranged to anode and cathode motion respectively under effect, and then exoelectrical reaction is completed in anode and cathode, in electricity
When intensity of flow is relatively low, more than its electric discharge precipitation rate, diffusion reaction dominates electrochemistry evolution reaction to the diffusion rate of zwitterion,
The electric discharge of cation strictly observes the deposition potential of each ion in solution sequentially, when current strength increases, the expansion of zwitterion
Scattered speed is sufficient to compensate between pole plate due to when the ion concentration that zwitterion electric discharge is caused changes, being formed strong tea polarization existing
As the precipitation of cation no longer strictly observes deposition potential sequentially, and electrochemistry evolution reaction starts a large amount of side reactions occur, with sulphur
In sour copper liquor as a example by acid copper, with the increase of current strength, concentration polarization phenomenon tends to obvious, and cathode hydrogen evolution is anti-
Should, begin participating in electrochemistry with copper ion deposition potential identical metal cation and separate out, the reduction of direct current electrical efficiency, cathode product

202430302 U；CN 102560560 A；U of CN 204918800 etc., cyclone electrolytic cell equipment metallurgical, environmental protection industry (epi) at home
Application field is extremely wide, but technology user is generally unsatisfactory for its actual working effect at this stage.In practical application example
Its production operation is complicated, maintenance maintenance is with high costs, evaporating, emitting, dripping or leaking of liquid or gas is serious, large-scale production efficiency is far below traditional plate channel type electricity
Deposition.No matter what difference the describing mode of the electrolysis such as eddy flow, jet, centrifugation has, and all simply the closed electro-deposition techniques of cylindrical shape are
Other people metaphysical imitation is different from, quickly to eliminate concentration polarization phenomenon using the electrolyte solution of high speed turbulence be only
Thus the science statement of new electro-deposition techniques, turbulent flow electrodeposition also arises at the historic moment, and in a word, rotational-flow electrolysis method and device are due to setting
, there is many unavoidable designs in actual industrialized production and lack in the standby not in place and unreasonable structure copied itself
