2 polarity of electrode of closed container inner wall two sides is opposite.
Multi-disc anion-exchange membrane is fixedly mounted in parallel between a pair of electrodes, behaviour is replaced with two steps of detergency using softening
Make；
1) when carrying out recirculated cooling water sofening treatment:
It is 50-300 A/m using current density2Direct current promote anion-exchange membrane close to cathode side water power from,
The OH of generation-Anion-exchange membrane and H are passed through under the action of electric field+Separation, anion-exchange membrane close to anode side with follow
HCO in ring cooling water3 ?、Ca2+ And Mg2+Reaction generates CaCO respectively3 With Mg (OH)2And it is deposited on anion-exchange membrane table
Face, hardness ions are removed in water, and basicity is reduced；Water flow that treated is discharged by water outlet perforated pipe；In treatment process,
The gas that two electrodes generate is discharged with water flow by water outlet perforated pipe.
2) when carrying out detergency processing:
Staggered poles polarity when detergency generates a large amount of H in original film side for depositing dirty layer+Reacting with dirty layer keeps it de-
It falls, the sediment to fall off is discharged with water flow from mud discharging mouth.
The working principle of the utility model is as follows:
1) when carrying out recirculated cooling water sofening treatment:
Mud discharging mouth valve is closed, 3 valve of water inlet perforation pipe is opened, recirculated cooling water inputs ionic membrane from water inlet perforation pipe 3
Electric deposition device 1, water flow is from bottom to top；The DSA electrode of two sides by wiring respectively with the positive and negative electrode of DC power supply or direct current
The negative, positive of source is extremely connected；DC power supply is opened, is 50-300 A/m using current density2Direct current promote anion exchange
Film is close to cathode side water power from the OH of generation-Anion-exchange membrane and H are passed through under the action of electric field+Separation, in anion
HCO of the exchange membrane in anode side and recirculated cooling water3 ?、Ca2+ And Mg2+Reaction generates CaCO respectively3 With Mg (OH)2And
It is deposited on anion exchange film surface, while the high concentration OH that cathode surface water electrolysis generates?, in recirculated cooling water
HCO3 ?、Ca2+ And Mg2+Reaction generates CaCO respectively3 With Mg (OH)2And it is deposited on cathode surface, hardness ions are gone in water
It removes, basicity is reduced；Hypochlorite Biocidal algae-killing agent can be generated on electrolytic process Anodic at the same time；Water flow that treated
It is discharged by water outlet perforated pipe 5；In treatment process, the gas that two electrodes generate is discharged with water flow by water outlet perforated pipe 5.
2) when carrying out detergency processing:
When dirty layer gradually covers anion-exchange membrane and cathode surface, it will lead to anion-exchange membrane and cathode performance lose
The problem of effect, it is therefore desirable to periodically carry out detergency processing.Before detergency, 3 valve of water inlet perforation pipe is first closed, and continue mud valve
It remains off, amberplex and electrode are totally submerged in solution；Then, the polarity for exchanging the DSA electrode of two sides, beats
DC power supply is opened, is 100~300 A/m using current density2Direct current promote water power from being originally covered with the anion of dirty layer
Exchange membrane side will generate high concentration H+, while the cathode for being originally covered with dirty layer will generate high concentration H as anode electrolysis water+, H+
With the CaCO inside dirty layer3 With Mg (OH)2Reaction makes it dissolve, and facilitates falling off for dirty layer, and the sediment of removing is handed over from anion
It changes film and cathode surface is transferred to water phase；During detergency, the gas that two electrodes generate is discharged from water outlet perforated pipe 5；Detergency
After, DC power supply is closed, mud discharging mouth valve is opened, the sediment of removing is discharged with water flow from mud discharging mouth 4.
