Moving electrode 1 among the present invention has 1-20, and fixed electrode 2 has 1-21, and it is circular that the shape of moving electrode 1, fixed electrode 2 is respectively.

Be operation principle of the present invention below:

Come sterilization by pulsed discharge under the normal pressure of liquid material or the low pressure, have more security and economy than high voltage electric field sterilization, its mechanism mainly is the result of comprehensive functions such as electrochemical sterilization, the sterilization of shock wave cavitation, galvanomagnetic-effect sterilization and local heat kill bacterium.Electrochemical sterilization and the sterilization of shock wave cavitation play a leading role.The pulsed discharge meeting forms 1 main discharge passage and numerous weak discharge passage in liquid.Main discharge channel center extreme temperatures when the discharge sterilization, biology can not be survived, but it is because minimum between the main discharge channel region, when measuring the processing fluid temperature, find, fluid temperature nearer from the main discharge passage and at a distance differs bigger, processed liquid does not produce stronger convection current during this explanation discharge, and the dominant mechanism of the sterilization of therefore discharging is not the heat kill bacterium.

Therefore, reach electrochemical sterilization and the sterilization of shock wave cavitation plays a leading role, electric discharge phenomena must be arranged, the discharge off phenomenon only plays some electrochemical sterilization effects.Only under the little situation in positive and negative electrode gap, could under routine or low-voltage, produce discharge, otherwise can only electrion, so adopt little gap.Difference such as (as electric conductivity) because the characteristic of liquid material needs to adjust the gap of positive and negative electrode, and the scope of this equipment is at 5～600mm.

The hyperacoustic key property of low frequency power is the machinery and the chemical affect of shock wave cavitation.So-called ' cavitation ' be meant when sound wave is propagated in medium, and be enough big as if the sound intensity, and the suffered negative pressure of liquid is enough strong, and the intermolecular average distance of medium will the value of overstepping the extreme limit, and the hole can be destroyed and occur to the integrality of liquid structure.A hundreds of atmospheric high pressure may appear in the moment in fierce contraction of cavitation bubble and collapse in the bubble, and the high temperature of thousands of degree.Also follow powerful shock wave (to homogeneous liquid) and speed to reach the jet (to heterogeneous liquid) of 400km/s during cavitation.

Therefore, for intensifying impact ripple cavitation, added ultrasonic unit.Because the cause (being created in the microcosmic spike place of positive and negative electrode spacing minimum) of main discharge passage, so require positive and negative electrode smooth surface and depth of parallelism height, better measure is a limit rotation moving electrode edge discharge, or the discharge again that rotates to an angle during the discharge off pulse, balanced main discharge passage and weak discharge passage, and the moving electrode of rotating band stirring action can be eliminated material better and accept the unbalanced phenomena that energy tells on, the entry level of discharging opening height and control, the dead angle beyond the elimination sparking electrode and the material of sneaking into sterilization of dead angle material.End liquid outlet is used for the separation and the extraction of material.

For reaching the optimum efficiency under the difference in functionality, it adjusts parameter has: pulse width, pulse interval width, pulse voltage and electric current; The gap of positive and negative electrode, the rotary speed of moving electrode and change between the stopping time; Hyperacoustic amplitude and frequency; Pulse and ultrasonic wave action time separately; By the entry level of valve control and the quantity of discharging (observing) by liquid level ruler.
