CDI type prefabricated stacked water treatment device {CDI-type prefabricated stacked water treatment device}

The present invention relates to a CDI (Capacitive Deionization) type prefabricated and stacked water treatment device. To be described in more detail, a plurality of plates with electrode plates formed therein are stacked in a manner that is fastened to each other to form one water treatment device. By constructing a separate case for sealing the electrode plate, the manufacturing cost of the water treatment device can be significantly reduced by eliminating the need for a separate case to seal the electrode plate. In particular, silicon packing is formed on each plate to maintain a stable watertightness of the electrode during the plate stacking process. Not only can the efficiency of the plates be guaranteed, but the treatment capacity of the water treatment device can be adjusted through a simple process of adjusting the number of plates to be stacked, so it is possible to provide a water treatment device with a treatment capacity appropriate for the installation site of the water treatment device. It is about a new type of CDI-type prefabricated and stacked water treatment device that can ensure stable water treatment while minimizing power use by providing power consumption of .

Capacitive deionization (CDI) technology is a technology that removes ionic impurities contained in raw water through the process of adsorption and desorption of ions in the electric double layer (EDl) formed at the charged electrode interface.

Specifically, when a voltage is applied within a potential range where electrolysis of raw water does not occur, the electrode is charged with a certain amount of electric charge. When brine water, which is raw water containing ions, is passed through this charged electrode, the ions in the raw water, which have an opposite charge to the charged electrode, move to each electrode by electrostatic attraction and are adsorbed on the electrode surface. The water that passes becomes desalinated water from which ions have been removed.

At this time, since the amount of ions adsorbed to the electrode is determined by the capacitance of the electrode, the electrode used in CDI is generally a porous carbon electrode with a large specific surface area.

On the other hand, when the adsorption capacity of the electrode is saturated, it cannot adsorb any more ions, so the ions in the inflow water may be discharged as they are included in the outflow water. Therefore, in order to desorb the ions adsorbed on the electrode, electrodes with saturated adsorption capacity are shorted or a potential opposite to the adsorption potential is applied to the electrode to regenerate the electrode by rapidly desorbing the adsorbed ions.

As such, CDI technology is known as an environmentally friendly desalination process that is very easy to operate and does not emit environmental pollutants during the desalination process because adsorption and desorption are achieved by changing the potential of the electrode.

To be described in more detail, a plurality of plates with electrode plates formed inside are stacked in a manner that is fastened to each other to form a water treatment device. By doing so, a separate case for sealing the electrode plate is unnecessary, which significantly reduces the manufacturing cost of the water treatment device. In particular, by forming silicone packing on each plate, stable watertightness can be guaranteed during the process of stacking the plates. In addition, the processing capacity of the water treatment device can be adjusted through the simple process of adjusting the number of plates to be stacked, so it is possible to provide a water treatment device with a processing capacity appropriate to the installation site of the water treatment device, providing optimal power usage. This is about a new type of CDI-type prefabricated and stacked water treatment device that can ensure stable water treatment while minimizing power use.

As shown, the CDI-type assembled and stacked water treatment device (A) according to the present invention has a unit cell 100 consisting of an electrode plate 20 on the inner upper surface and a plate 10 with silicon packing 30 formed on the edge. A plurality of units are stacked, and the stacked state of the unit cells 100 is physically fixed to form one water treatment device (A).

The unit cell 100 is formed on both sides with an inlet hole 11 through which raw water flows in and an outlet hole 12 through which water-treated raw water is discharged, and on the inside is a contact treatment space where raw water is treated by contacting the electrode plate 20. (13) is formed to communicate with the inlet hole (11) and the discharge hole (12) and has a plurality of locking devices (14) and fastening grooves (15) formed on the edges of the plate (10), and the plate (10) An electrode plate 20 is seated on the upper surface and is made of graphite in the form of a carbon film, and is formed on the edge of the electrode plate 20 to prevent raw water flowing into the contact treatment space 13 from leaking out of the plate 10. It consists of a silicon packing (30).

In addition, the plate 10 is formed with a plurality of electrode penetration holes 16 through which the negative electrode and the positive electrode pass.

In addition, during the stacking process, the plate 10 forms a support bar 17 in the center of the contact processing space 13 to prevent distortion or bending due to the hollow interior of the contact processing space 13. By dividing the contact treatment space 13, the incoming raw water is encouraged to spread smoothly radially, and at the same time, the electrode plate 20 formed on the upper part of the plate 10 is stretched into the contact treatment space 13 by the load. It is necessary to physically prevent the movement of enemies.

In addition, the inlet hole 11 and the outlet hole 12 are formed to communicate with the internal contact treatment space 13 and the tunnels 111 and 121, so that raw water flowing in through the inlet hole 11 flows into the tunnel 111. It is moved to the contact treatment space 13, comes into contact with the electrode plate 20, is purified, and then flows in and out of the discharge hole 12 through the tunnel 121 in communication with the discharge hole 12. .

Additionally, the tunnels 111 and 121 may be formed in a radial shape that gradually widens outward so that raw water can be quickly and uniformly introduced and discharged into the contact treatment space 13.

Meanwhile, the plate 10 firmly maintains the stacked state through a plurality of locking devices 14 and fastening grooves 15 formed on the edges.

That is, in the case of the plate 10 having a square shape as shown in FIG. 4, one locking device 14 and one fastening groove 15 are fastened with three sets of locking devices 14 on one side. As the groove 15 is formed, 12 sets of locking devices 14 and fastening grooves 15 are formed on the four sides as shown.

In addition, the neighboring plates 10 are formed by changing the positions of the locking claws 14 and the fastening grooves 15 so as to be coupled to the upper or lower part of the plate 10, so that the locking claws 14 of the plate 10 are substantially ) is fastened to the fastening groove 15' of the neighboring plate 10', so that each plate 10, 10' is firmly fastened.

The fastening of the plate 10 as described above is equally fastened in the locking device 14 and the fastening groove 15 formed on the four sides, so that the entire plate is fastened with the same fastening pressure, so that the same pressing force is applied to the silicon packing 30 formed inside. It has the characteristic of maintaining a solid watertight state by applying this.

On the other hand, the plate 10 configured as above is stacked accurately by the loading means 19, which consists of a protrusion 191 and a loading groove 192 formed on the edge during the process of stacking a plurality of plates. By being guided to be loaded in this state, the process of fastening the locking device 14 to the fastening groove 15 can be smoothly performed.

The loading means 19 is formed by bending the edge of the plate 10 upward to have an approximately “L” shaped cross-section, and has a protrusion 191 at the top and a laminated groove 192 into which the protrusion 191 is inserted at the bottom. ) is composed of.

As shown in FIG. 8, the protrusion 191 formed on the plate 10 is inserted into the stacking groove 192' of the neighboring plate 10' loaded on top by the loading means 19 configured as above.

By continuously repeating the above stacking process, it is possible to provide a water treatment device with a treatment capacity suitable for the installation environment.

In addition, the protrusion 191 and the locking device 14 of the loading means 19 are configured at the same height, so that there is no partial protrusion or depression due to a difference in height when the plates 10 are stacked, thereby maintaining the stacked state of the plates. It has the characteristic of being sturdy.

Moreover, in the process of fastening the locking device 14 to the fastening groove 15, the locking device 14 is hooked and fastened to the protruding protrusion 151 formed inside the fastening groove 15, so that the locking device 14 ) in the process of being coupled to the adjacent plate 10' on which the plate is stacked, the locking device 14 is caught inside the fastening groove 15', thereby preventing it from protruding upward and ensuring a solid fastening state. .

Meanwhile, in order to stably maintain the installation position of the silicon packing 30 formed to seal the contact processing space 13, a fitting groove into which a part of the silicon packing 30 is inserted into the edge of the contact processing space 13 (18) can be formed.

The electrode plate 20 is composed of a thin carbon film made of graphite, and has a first through hole 21 located at the edge on the same line as the inlet hole 11 and the outlet hole 12 of the plate 10. A second through hole 22 located on the same line as the electrode through hole 16 is formed so that raw water can move smoothly and at the same time, the cathode tube (not shown) and the anode tube (not shown) can be smoothly combined. .

The silicone packing 30 has elasticity so that it can be deformed during the process of close contact between the plate 10 and the neighboring plate 10', and a plurality of protrusions 31 are formed on the upper portion of the silicone packing 30. It is pressurized and deformed between each plate (10, 10') to prevent raw water from leaking out of the plate (10).

As described above, the electrode plate 20 and the silicon packing 30 are formed on the top of the plate 10 to form one unit cell 100, and the unit cell 100 is adjusted to suit the water treatment capacity of the installation environment. By stacking multiple devices to provide one water treatment device (A), it has the feature of stably treating contaminated raw water while minimizing the use of electrical energy.

That is, the neighboring unit cells 100' stacked on top of the unit cells 100 can be maintained in the correct position without being distorted by the configuration of the loading means 19 formed on the plate 10 during the stacking process. At the same time, the stacked plates can be fastened with uniform bonding force through the combination of the plurality of locking devices 14 formed at the edges of the plate 10 and the fastening groove 15, so that the entire silicon packing 30 is pressed inside. By providing the same pressing force to the water, it is possible to ensure a solid watertight condition without leakage of raw water.

As described above, the CDI-type prefabricated stacked water treatment device according to the present invention has a compact appearance because the plate forms a flow path inside which raw water can move and can provide as much water treatment space as possible in contact with the electrode plate. However, it has the feature of being able to provide high water treatment capacity.

In addition, a water treatment device is formed by stacking a plurality of plates on which electrode plates are formed, and the stacked plates serve as a housing for the water treatment device in parallel, thereby eliminating the need for a separate case or other configuration to accommodate the electrode plate, thereby reducing the production cost of the water treatment device. Not only can it significantly reduce water consumption, but the electrode plate that purifies water through the water treatment device through the silicon packing formed on the edge of the plate can physically block raw water from leaking out of the plate by the silicon packing formed on the edge. It is composed of a stack of multiple plates with electrode plates formed inside, so the water treatment device can be modified to a treatment capacity appropriate for the installation environment where water treatment is required, providing excellent field applicability and minimizing power consumption. It has structural features that can significantly reduce the maintenance costs of water treatment devices.

In addition, the water treatment device consists of a simple structure of stacking and connecting a plurality of plates with electrode plates formed inside, which not only significantly reduces manufacturing costs, but also has an overall slim and compact appearance. It has the characteristic of being easy to handle and maintain.
