Description
Technical field
The present invention relates to capacitive deionization technical field, in particular to a kind of capacitor deionizing instrument, system and capacitor are gone
Ion method.
Background technique
Traditional capacitance deionizer is will be a pair of or several be placed on two capacitive deionizations to the adsorption electrode being placed in parallel
Among module, it is placed in capacitor deionizing instrument in water flow, when water flow flows through adsorption electrode, the ion in solution can be adsorbed
On the electrode, solution concentration is reduced, this mode will increase the internal resistance of entire electrode, after causing operating cost excessively high
Fruit.Further, since the reason of water self gravity, water flow can not cover entire electrode, cause the drop of the effective contact area of electrode
It is low.
Summary of the invention
In view of this, it is necessary to provide a kind of capacitor deionizing instrument, system and capacitive deionization methods.
The embodiment of the present invention provides a kind of capacitor deionizing instrument characterized by comprising electrode is to, electrode to support
Frame, plexiglass box, for the collector of energization, the water inlet pipe for being connected to former pond and for being connected to water purifying tank
Outlet pipe, the electrode include the first electrode storing face being oppositely arranged, second electrode storing face, water inlet to support frame and go out
The mouth of a river, the electrode to including the first carbon resistance rod and the second carbon electrode, put face and be placed with first carbon resistance rod by first electrode,
The second electrode puts face and is placed with second carbon resistance rod, useful between first carbon resistance rod and second carbon resistance rod
In the water storage hollow structure for putting the pending water from former pond, the water storage hollow structure and the water inlet and it is described go out
The mouth of a river is connected；The capacitor deionizing instrument includes that at least two pairs of electrodes pair and at least two are used to support placement institute
The electrode of electrode pair is stated to support frame, is placed with amberplex between the two neighboring electrode pair；All electrodes pair
And all electrodes are respectively positioned in the plexiglass box support frame, the plexiglass box is a kind of thick inner wall
Sealing container, the water inlet pipe passes through the plexiglass box and is communicated to the water inlet, and the outlet pipe passes through described
Plexiglass box is communicated to the water outlet, when being packed into the pending water in the capacitor deionizing instrument, with it is described to
After the collector energization for handling water phase contact, the capacitor deionizing instrument carries out capacitive deionization to the pending water
Operation.
The embodiment of the present invention also provides a kind of capacitive deionization system characterized by comprising for holding pending water
Former pond, first capacitor deionizer, the second capacitor deionizing instrument, third capacitor deionizing instrument and the 4th capacitor go
Ion unit, the water purifying tank for holding after deionization is handled gained water and the transition pond for controlling inflow, are also wrapped
Include it is for power supply, with the first capacitor deionizer, second capacitor deionizing instrument, the third capacitor go from
The power supply that sub-device and the 4th capacitor deionizing instrument are electrically connected；It states former pond and is connected to the transition pond, the mistake
Valve V1, a filter and the first water flow for monitoring water flow concatenated for controlling water flow is crossed on the water pipe in pond
Shunt conduit is used after meter, the shunt conduit concatenation valve V2 is connected to the water inlet of the first capacitor deionizer
Pipe, the shunt conduit also concatenate the water inlet pipe that valve V3 is connected to the third capacitor deionizing instrument, second capacitor
The water inlet pipe of deionizer is connected to the outlet pipe of the first capacitor deionizer, second capacitor deionizing instrument
Outlet pipe connect and access valve V4 after the first conductivity meter, the water inlet pipe of the 4th capacitor deionizing instrument is connected to described
Outlet pipe the second conductivity meter of series connection of the outlet pipe of third capacitor deionizing instrument, the 4th capacitor deionizing instrument is followed by
Enter the valve V4；The valve V4 series connection is for opening the valve of the gained water to the water purifying tank after deionization is handled
The water purifying tank, the valve that the valve V4 also connects for making water flow be back to the transition pond are accessed after V5, second flowmeter
The transition pond is accessed after door V6, third flowmeter；The transition pond is placed with the liquid level for monitoring the transition water amount
Sensor；The first capacitor deionizer, second capacitor deionizing instrument, the third capacitor deionizing instrument and
4th capacitor deionizing instrument is capacitor deionizing instrument above-mentioned.
The embodiment of the present invention also provides a kind of capacitive deionization method, comprising:
Power supply is first capacitor deionizer, the second capacitor deionizing instrument, third capacitor in capacitive deionization system
Deionizer, the power supply of the 4th capacitor deionizing instrument, the capacitive deionization system are capacitive deionization system above-mentioned；
Valve V1 in the open capacitive deionization system, in former pond pending water flow through transition pond, filter and
Enter shunt conduit after first flowmeter；
Open valve V2, makes the pending water flow into the first capacitor deionizer；
The first capacitor deionizer carries out capacitive deionization processing to the pending water, and will be through described first
Treated that water is exported to second capacitor deionizing instrument for capacitor deionizing instrument；
Second capacitor deionizing instrument to it is described through the first capacitor deionizer treated water again into
The processing of row capacitive deionization, and will treated that water is exported to valve V4 through second capacitor deionizing instrument；
First conductivity meter measures first conductivity through second capacitor deionizing instrument treated water, if
First conductivity is no longer continued to decline compared to the conductivity values that the first conductivity meter last time measures, then is opened
Through second capacitor deionizing instrument, treated that water is exported to water purifying tank by described by valve V5；If the first conductivity phase
It is continued to decline than the conductivity values that are measured in the first conductivity meter last time, then opens valve V6 for described through described the
Treated that water is exported to the transition pond for two capacitor deionizing instruments；
