The present invention relates to a fiber filtration device, and more particularly, to a fiber filtration device including a conductive fiber yarn capable of removing ions together with a suspended material in water by using a conductive fiber yarn as a fiber filtration material.

The fiber filtration device refers to a filtration device that uses a fiber yarn as a filter medium to filter foreign matter in the liquid to be treated, and uses a gap between the fibers as a filter gap.

Various suspension substances and ionic substances are contained in the water of the process target liquid filtered by such a fiber filtration apparatus. In order to remove the ions in the water, it is deionized by an ion exchange resin having a chemical charge and separated by specific gravity difference. There is an electrodialysis method in which the de-ionized material is separated and filtered by a membrane after the continuous supply of charge consumed by the electrode without treatment. However, in order to prevent contamination of the ion exchange resin by the suspended material in water, they need a separate pretreatment filter for removing the suspended material and undergo a separation process by a membrane, thereby limiting the processing capacity. In addition, the pores of the normal granular ion exchange resin must be periodically replaced due to contamination as time passes even if the suspension material is removed.

When electrical energy is supplied from the power supply member to the fiber filtration unit, the ionic material may be removed together with the foreign matter in the liquid to be treated in the conductive fiber yarn.

According to a fiber filtration device including conductive fiber yarns according to an aspect of the present invention, a first fiber filtration unit and a second fiber filtration unit each including conductive fiber yarns are connected in series, one of which is a suspension material and a cation. For removal, the other is applied for removal of residual suspensions and anions, thereby eliminating the need for chemical treatment and exchange of ion exchange resins, and without the need for a pretreatment to prevent contamination by suspensions of ion exchange resins. It is possible to remove dissolved ionic substances and to have advanced water treatment when replaced with activated carbon filter instead of separation tank.

According to the fiber filtration apparatus including the conductive fiber yarn according to another aspect of the present invention, during the filtration it is generated during ion exchange by varying the supply voltage of the electrode according to the ion concentration in the raw water to be treated and applying a reverse voltage for a period of time. By removing the plating on the surface of the conductive fiber yarn of the solid material after the ion exchange and the possible gas, there is an effect that can facilitate the contact of the other ions to increase the ion removal efficiency.

The connector opening / closing valve 383 is in an open state, and the hydroxide that sinks to the bottom of the first fiber filtration tank 311 through the connection pipe 370 connected to the upper portion of the first fiber filtration tank 311 is 1. After separating by the specific gravity difference from the primary treated water, such primary treated water flows to the second fiber filtration unit 200. At this time, the second backwash water discharge branch pipe open / close valve 382 is in a closed state.

The cathode of the second power supply member 410 is connected to the filtration unit case 210 of the second fiber filtration unit 200, and the anode of the second power supply member 410 is the second fiber filtration. Since the conductive fiber yarns 220 in the second fiber filtration unit 200 are bipolar because they are connected to the corrugated filter barrel 230 of the unit 200, the second fiber filtration unit 100 Negative material of the ionic material in the liquid to be treated in the fluid to meet the polarity of the conductive fiber yarns 220 to form an acidification material with the deionized water through the second fiber filtration unit discharge pipe 361 After flowing into the second fiber filtration tank 312, it sinks to the bottom of the second fiber filtration tank 312.

The final treatment water in which the acidified material which has settled to the bottom of the second fiber filtration tank 312 is separated through the filtrate discharge pipe 350 connected to the upper portion of the second fiber filtration tank 312. By being introduced into, the deionization and filtration are performed in the fiber filtration device 300.

Meanwhile, as shown in FIG. 10, the voltage applied from the first power supply member 400 to the first fiber filtration unit 100 may vary depending on the amount of ionic material in the treatment liquid.

That is, when there is a large amount of ionic material in the liquid to be treated, there are more opportunities for the ionic material to contact the conductive fiber yarn 120, which is a conductor, and a large amount of electric charge is required, thereby increasing the amount of current. When less, the less ionic material is less likely to contact the conductive fiber yarn 120, which is a conductor, the less electric charge is required and the amount of current is reduced. Therefore, when there is a large amount of ionic material in the liquid to be treated and a large amount of current flows, a high voltage is not required because a large amount of charge is required and particle acceleration suction is not required to expand the contact opportunity of the ion particles, and accordingly, FIG. As shown by the dashed line, the voltage is lowered to eliminate losses other than charge replenishment, thereby suppressing the temperature rise of the treated raw water. On the other hand, when a small amount of ionic material flows in the liquid to be treated, and a small amount of current flows, a high voltage is required because much charge is not required and particle acceleration suction is required to increase the contact chance of the ion particles. As shown by the solid line, the voltage is increased to increase the efficiency of ionic material removal.

Such voltage regulation may also be made in the second fiber filtration unit 200. That is, as shown in FIG. 11, only the polarity of the voltage applied from the second power supply member 410 to the second fiber filtration unit 200 is opposite to that of the first fiber filtration unit 100. Treated by supplying polarity.

That is, when there is a large amount of ionic material in the liquid to be treated, the chance of contacting the conductive fiber yarn 220 that is a large amount of the ionic material is increased, and a large amount of electric charge is required to increase the amount of current. When less, the less ionic material is less likely to come into contact with the conductive fiber yarn 220, which is a conductor, and the less electric charge is required, thereby reducing the amount of current. Therefore, when a large amount of ionic material is present in the liquid to be treated and a large amount of current flows, a high voltage is not required because a large amount of charge is required and particle acceleration suction for expanding the contact chance of the ion particles is not required. As shown by the dotted lines, the voltage is lowered to eliminate losses other than charge replenishment. On the other hand, when there is less ionic material in the liquid to be treated and the current flows in a small amount, a high voltage is required because much charge is not required and particle acceleration suction is required to increase the contact chance of the ion particles, and accordingly, FIG. As shown by the solid line, the voltage is increased to increase the efficiency of ionic material removal.

The sensing of the current for adjusting the voltage may be performed by a sensor (not shown) such as a hall sensor installed in each of the power supply members 400 and 410.

On the other hand, when the ionic material in the object to be treated is removed in the fiber filtration unit (100, 200) as described above, a variety of gases may be generated according to the type of ions to be removed, such gas is the conductive fiber yarn ( 120, 220, the effective filtration area of the conductive fiber yarns 120, 220 may be reduced, so that in order to remove such gases, a relatively short period of time t2 compared to the filtration period t1 may be reduced. Supply reverse voltage. This reverse voltage supply may be supplied periodically and repeatedly.

Here, the reverse voltage is applied, for example, the cathode of the first power supply member 400 is connected to the filtration unit case 110 of the first fiber filtration unit 100, the first power supply The anode of the member 400 is configured to be connected to the corrugated strainer 130 of the first fiber filtration unit 100, the anode of the second power supply member 410 is the second fiber filtration unit 200 It is connected to the filtration unit case 210, the cathode of the second power supply member 410 is configured to be connected to the corrugated filter barrel 230 of the second fiber filtration unit 200.

As described above, during the filtration process in the fiber filtration unit (100, 200), a reverse voltage of the constant voltage applied to the conductive fiber yarns 120, 220 for filtration is the conductive fiber yarn 120 for a predetermined time (t2) , 220, the gas or ionic material adhering to the surfaces of the conductive fiber yarns 120 and 220 can be removed, thereby preventing a decrease in filtration efficiency of the conductive fiber yarns 120 and 220.

In addition, as described above, the first fiber filtration unit 100 and the second fiber filtration unit 200 including the conductive fiber yarns (120, 220), respectively, in series, one of which is for cation removal In addition, the other is applied for removing anions, so that not only foreign matter in the liquid to be treated, but also ionic substances in the liquid to be treated can be removed.

The power supply members 400 and 410 step down the input voltage single-phase 220V to about 3V with a step-down transformer and rectify it to DC 3V, and use this as the main power to sense the current according to the electrical conductivity of the raw water to be processed by the Hall sensor. Inversely, the PWM duty ratio is determined to generate a PWM pulse, which is switched by an insulated gate bipolar transistor (IGBT) according to this signal and then rectified again to generate a desired variable DC of 0.5 to 3V.

As such, the first fiber filtration unit 100 and the second fiber filtration unit 200 each including the conductive fiber yarns 120 and 220 are connected in series so that one of them is for removing cations and the other By applying one for removing anions, not only suspended and solid substances in the treatment liquid, but also ionic substances in the raw water to be treated can be removed.

On the other hand, if the filtration process as described above, when the impurities are accumulated in the conductive fiber yarns (120, 220), the filtration pressure increases, but exceeds the rust of the pH meter of the first fiber filtration tank 311 Or backwashing is required when the pH meter of the second fiber filtration bath 312 is below the set point.

During this backwashing, the backwash water supply pump 391 is operated, so that the backwash water flows along the backwash water supply lamination pipe 341 with the filtered water in the final treatment tank 310 as the backwash water. Of course, water other than the filtered water in the final treatment tank 310 may be used as backwash water.

The first backwash water supply branch pipe open / close valve 384 and the second backwash water supply branch pipe open / close valve 385 are opened, so that the backwash water is supplied to the first backwash water supply branch pipe 342 and the second backwash water supply. It is fed into the first fiber filtration unit 100 and the second fiber filtration unit 200 through the branch pipe 343, respectively.

In this backwashing process, the connection pipe open / close valve 383 and the raw water supply pipe open / close valve 380 are closed, and the first backwash water discharge branch pipe open / close valve 381 and the second backwash water discharge branch pipe open / close valve 382 are closed. Is in an open state, and the conductive fiber yarns 120 and 220 are in a relaxed state, respectively, as shown in FIG. 4.

The backwash water supplied to the first fiber filtration unit 100 and the second fiber filtration unit 200 flows from the inside of the corrugated filter barrels 130 and 230 to the outside, respectively. The conductive fiber yarns 120 and 220 which are loosened by blowing compressed air into the lower portion of the first fiber filtration unit 100 and the second fiber filtration unit 200 are accumulated in the conductive fiber yarns 120 and 220. ) Backwash water containing foreign matter and ionic material separated from the conductive fiber yarns 120 and 220 by shaking the backwash water in the first backwash water discharge branch 332 and the second backwash water discharge branch 333, respectively. After passing through) is discharged to the outside together with the concentrate of the first fiber filtration tank 311 and the second fiber filtration tank 312 through the backwash water discharge lamination pipe 331. Through this process, backwash can be achieved.

Meanwhile, during the backwashing process as described above, as shown in FIGS. 12 and 13, the constant voltage and the reverse voltage are alternately repeatedly applied to the conductive fiber yarns 120 and 220, respectively. Then, all materials that may be plated on the conductive fiber yarns 120 and 220 may be separated from the conductive fiber yarns 120 and 220 and discharged to the outside.

After the backwashing is completed, the conductive fiber yarns 120 and 220 may be tightened again, and the filtration process may be performed again.

The top cover can be easily opened in one operation and the conductive fiber media can be replaced immediately on site. In addition, if a high degree of water treatment is required, it is possible to replace the fiber filtration separation tank with an activated carbon filter, so the application range is wide. In addition, by supplying a variable voltage in accordance with the amount of dissolved ions in the raw water to be treated, it is possible to reduce the power consumption for ion dialysis unnecessarily and to suppress the temperature rise of the treated water. In addition, in the case of low ion dissolved water, the ion removal efficiency may be increased by increasing the supply voltage for accelerating the ion and increasing the suction force.
