Specific embodiment and principle:
First clean unit 2' for being purified to the stoste in source of supply 200, to the stoste in source of supply 200 into Before row purification, first passing through control circuit makes circulation capacitor 4 be in the charging stage, waits the circulation capacitor 4 in the first clean unit 2' Expected operating voltage, about 1.6V are loaded and reached, into working stage, is then controlled accordingly by drive control device 24 Solenoid valve open and close, first supply pipe road 50' and first service branch 80' is connected, and the first conveying branches 130' It evacuates branch 90' with first to disconnect, the stoste in source of supply 200 flows to clean unit 2 by supply line 5, clean unit 2 Capacitor 4 circulate during working stage, therefore the particle ionized is attracted with the polar respective electrode opposite with them, is led Ionizing particle building up in identical electrodes, so that the purification of stoste occur;
As purification carries out, the electrode of circulation capacitor 4 can be increasingly saturated, and will have polarizable particles in fluid, immediately Into regeneration stage, at this stage period, disconnect the first evacuation branch 90', and first supply pipe road 50', the first conveying point Branch 130' and first service branch 80' conducting, the first scrub stream flow out into the first clean unit 2' from holding vessel 12, force Include the cleaned stoste in the first clean unit 2' and in extraction conduit 7 towards the diffluence of services branch 8, is then shut off institute There is a valve, then discharge regime is again at by the control circuit capacitor 4 that makes to circulate, then by first supply pipe road 50', first defeated Branch 130' and first is sent to evacuate branch 90' conducting, first service branch 80' disconnection, the first scrub stream is left holding vessel 12, worn The first clean unit 2', the ionizing particle of removal accumulation on the electrode are crossed, and is transmitted back to holding vessel 12, carries out the first scrub stream Circulation;
After the first scrub stream recycles a period of time, the first conveying branches 130', first are evacuated into branch 90' conducting, the One conveying branches 130' and first service branch 80' is disconnected, and source of supply 200 flows out stoste and serves as the second scrub stream, the second washing Stream flows to the first clean unit 2', flow back into holding vessel 12 until by the first evacuation branch 90', the second scrub stream can be Replacement is present in the first scrub stream of high concentration ionizing particle in first clean unit 2', and it can also remove and be still in The residual ionizing particle to circulate on the electrode of capacitor 4, when liquid reaches horizontal quota in holding vessel 12, or when setting interval Between and after interval time reaches, open the 5th valve 16 with the ionizing particle containing high concentration inside certain flow rate discharge holding vessel 12 Liquid, and the second washing flow velocity for reaching holding vessel 12 is substantially equal to the concentration being discharged by delivery pipe 15 from holding vessel 12 The flow velocity of fluid, which is set smaller than 5% of the overall flow rate from the first clean unit 2' processing and the fluid purified, optimal Choosing is set as 2%;
Finally so that circulation capacitor 4 is first in the no-voltage stage for a period of time by control circuit again, is then again introduced into and fills The electric stage waits the circulation capacitor 4 in the first clean unit 2' to load and reaches expected operating voltage, into work rank Then section is connected first supply pipe road 50' and first service branch 80', and the first conveying branches 130' and first is evacuated and divided Branch 90' is disconnected, and carries out stoste purification again, while being switched to the second clean unit 2 " and starting to wash;
The washing process and principle of second clean unit 2 " are identical as the washing process of the first clean unit 2' and principle, and two One progress stoste of person purifies another and washs, and switching staggeredly carries out.
Based on above-mentioned, clean unit is arranged in the present invention, and the salt in solution, ammonia and other polarization are removed by the way of ionization Pollutant and chemical substance, organic substance or micropollutants also cooperate holding vessel to carry out clean unit by hydraulic system It washs, has not only played the role of to clean unit reactivation twice, but also have collected the isolated ionizing particle of electricity, and high concentration will be contained Ionizing particle liquids recovery into holding vessel, recycled convenient for subsequent discharge, the first cleaning solution and second washs in this system Liquid is derived from source of supply, does not need to introduce clean liquid from the external world, also not need using filter material, clean-up effect of the present invention It is good, and recycling is collected to pollutant, secondary pollution will not be generated without expending other resources.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature Case is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.Institute Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
