Adopt technique scheme, 1, scavenging solution selects neutral salt solution, it, not containing soda acid, need not carry out waste liquid process, also can not work the mischief to environment.2, the first electrode and the second electrode connect direct supply or the pulse power, telegraph circuit connects into a current path together with scavenging solution, under the effect of electric current, neutral salt solution negative ions produces and moves freely, first be immersed in portion in conductive shell at shape and form bubble, then negative ions is when reaching enough current densities, excite bubble, and produce plasma, mechanical shock effect and thermal coupling effect are carried out to the greasy dirt, oxide skin etc. on shape surface, reaches the object of surface cleaning and leveling.3. ultrasonic wave can make shape surface smut and oxide skin come off uniformly rapidly, reduces action time, can not cause surface damage because of the timeout treatment of fluid plasma.4, in the method, insulation shell effectively can cover shape electric field in the solution, make its shaded portions not produce plasma, be conducive to the isoionic formation in conductive shell, improve cleaning efficiency and cleaning performance, reduce voltage, can save energy and cost.There is band large-scale metal section bar (as sheet material) to need clear, small area can be selected to clean, until each part has been cleaned.
In technique scheme: described shape is wire or metal bar, described conductive shell is conduction pipe, and described insulation shell is insulation pipe, and described wire or metal bar are through baffle.
As preferably: the carbonate solution of described scavenging solution to be concentration be 3%-15% or halide solution or sulfate liquor.The salts solution of such concentration, had both possessed good cleaning performance, and shape also can be protected not to be damaged.
As preferably: the diameter of described insulation pipe 50%-100% larger than the diameter of wire or metal bar, length is determined by the size of rinse bath.The diameter 10%-20% larger than the diameter of insulation pipe of described conduction pipe, the length of described conduction pipe is 3mm-500mm.Make wire or metal bar well by baffle, meanwhile, the bridging effect of insulation pipe can be ensured, and form plasma body in conduction pipe.
As preferably: described conductive shell is made up of graphite or inert metal or stainless steel or alumino nickel.Can not produce electrolysis at scavenging solution when being energized, affecting cleaning solution.Graphite Electrodes also has the low effect of cost simultaneously.
As preferably: described insulation shell is made up of PVC or PP or PE or stupalith.
As preferably: described stupalith is aluminum oxide or silicon oxide or silica glass.
As preferably: in step C, scavenging period is 0.2min-30min.The impurity such as greasy dirt and oxide skin on metal bar or silk material surface can be disposed, also itself can not cause damage to metal bar or silk material.
As preferably: the temperature of described scavenging solution is that room temperature is to 98 DEG C.
As preferably: in step D, the translational speed of described shape is 0.1mm/s-100mm/s.
Beneficial effect: the present invention can remove shape surface contaminants fast and effectively, this cleaning technique surface cleaning can not only be obtained enough light and clean, cleaning performance is good, cleaning efficiency is high, energy-conservation and waste liquid also can not bring problem of environmental pollution.
