Specific embodiment
The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments
As shown in Figure 1, Figure 2, Figure 3 shows, electrochemical reactor 1 be a top be cuboid, bottom be funnel shaped container,
The positive lower part of cuboid is provided with water inlet 7, and funnel bottom is mud discharging mouth 9, and the top at the cuboid back side is provided with overflow seam 6, overflows
Stream seam 6 is connected to external catch basin 10, and 10 lower part of catch basin is provided with water outlet 5；Electrochemical reactor at face water inlet 7
Water fender 8 is equipped in 1；Two lateral electrodes 2 and 3 equidistant vertical of target are embedded in the front and back of electrochemical reactor 1
In slot.
The spacing of the adjacent electrode of two lateral electrode 2 and target 3 is 2~10 mm, is the DSA electricity of plate
Pole.
Two lateral electrode 2 and target 3 are by recess-mounted that depth is 3~10 mm in electrochemical reactor 1
In the slot of front and back.
It is coated with insulating layer within the scope of 10~50 mm of upper and lower part of two lateral electrode 2 and target 3, or
The upper and lower part of two lateral electrode 2 and target 3 is equipped with insulating barrier 4 (as shown in Figure 1 and Figure 2), with
Prevent when handling high conductivity raw water electric current from 3 surrounding of target across causing current efficiency to be remarkably decreased.
Two lateral electrodes, 2 upper end all has protrusion part, and protrusion part is drilled with aperture, connects with wiring by the way that screw is fixed
It connecing, wiring is connected with the positive and negative electrode of power supply respectively again, and the target 3 is connected without wiring, in galvanization, intermediate electricity
The one side of pole 3 is anode, and the another side of target 3 is cathode.
The dirty layer that cathode surface deposits in the electrochemical reactor is removed by the way of pole.
The working principle of the utility model is as follows:
1) when carrying out industrial circulating cooling water processing:
Mud discharging mouth valve is closed, water inlet valve is opened and outlet valve, recirculated cooling water inputs electrification from water inlet 7
Reactor 1 is learned, carries out water distribution uniformity using water fender 8, water flow passes through electrochemical reactor 1 from bottom to top；The DSA electrode of two sides
It is connected respectively with the positive and negative electrode of DC power supply by wiring, intermediate DSA electrode is connected not over wiring；Open direct current
Source applies direct current to electrochemical reactor 1, is 10-300 A/m using current density2Direct current promote water electrolysis, it is intermediate
DSA electrode be on one side anode, another side is cathode；Using the hypochlorous acid generated on electrolytic process Anodic to recirculated cooling water
Carry out sterilization algae removal；Utilize the high concentration OH generated on cathode?, with the HCO in recirculated cooling water3 ?、Ca2+ And Mg2+Reaction point
It Sheng Cheng not CaCO3 With Mg (OH)2And it is deposited on cathode surface, the hardness ions in water are removed；Treated water is through overflow seam 6
Catch basin 10 is flowed into, then is discharged by water outlet 5；In treatment process, the gas that two electrodes generate relies on natural buoyancy from electrification
It learns and is discharged at the top of reactor 1.
When handling high conductivity raw water, coated on insulating layer or electrode if not descending within the scope of 10~50 mm on the electrode
Lower placement insulating barrier 4, then since about 3 resistance per square of target is small, electric current is easily crossed over from about 3 target and causes electric current
Efficiency is remarkably decreased；And insulating layer or electrode placement insulating barrier 4 up and down are coated within the scope of lower 10~50 mm on the electrode
Afterwards, due to elongated across path, resistance increases, and electric current is not easy to cross over from about 3 target, and current efficiency significantly improves.
2) when carrying out cathode detergency processing:
When dirty layer gradually covered cathode surface, the problem of cathode performance fails will lead to, it is therefore desirable to periodically to cathode
Surface carries out detergency processing.Allow electrode to be totally submerged in solution, using controller or manually control exchange two sides DSA electrode
Polarity, the original cathode plane of target will become anode surface, and original anode surface will become cathode plane；Open direct current
Source applies direct current to electrochemical reactor 1, is 100~300 A/m using current density2Direct current promote water electrolysis, it is former
The cathode plane for being first covered with dirty layer will generate high concentration H as anode+, H+With the CaCO inside dirty layer3 With Mg (OH)2Reaction makes it
Dissolution, facilitates falling off for dirty layer, the sediment of removing is transferred to water phase from cathode surface；During detergency, two electrodes are generated
Gas be discharged at the top of electrochemical reactor 1 by natural buoyancy；After detergency, DC power supply is closed, opens mud discharging mouth
The sediment of removing is discharged valve from mud discharging mouth 9.
Embodiment:
Hardness is about 950 mg/L, and conductivity is 3482 μ S/cm, and inhibitor concentration is about the industrial circulating water of 2 mg/L
It is handled using utility model device.The device includes six pieces of DSA plate electrodes, and the size of electrode is 100 mm × 100
The mm of mm × 2, the clear spacing between two electrodes are 10 mm.Depth of groove is 5 mm, and insulating barrier width is 10 mm.
Operating condition is as follows: processing stage current density is 75 A/m2, 25 L/h of water velocity lasts 12 h；Cathode is de-
Dirty 100 A/m of stage current density2, 5 min of detergency time.When electrode upper and lower part installation insulating barrier, total hardness of water out
For 808 mg/L.In contrast, when electrode upper and lower part do not install insulating barrier, total hardness of water is 847 mg/L out.
When not installing insulating barrier, hardness removal amount is the mg/L of 950mg/L-847 mg/L=103；Insulating barrier is installed
Afterwards, hardness removal amount is the mg/L of 950mg/L-808 mg/L=142, therefore hardness removal amount increases after installation insulating barrier
(142-103)/103=37.9%.Softening efficiency when installing insulating barrier increases 37.9% when not installing insulating barrier.
