The body 100 is formed in a cylindrical shape having a space therein, and may be formed of, for example, a cylindrical shape or a polyhedron. A gas inlet portion is formed on one side of the first side wall of the main body 100 and a base body 2 containing contaminants from the outside through the gas inlet portion 110 may be introduced into the main body 100 have. In this case, it is obvious that the gas inlet 110 may be installed at the upper end of the main body 100 and may be installed at various positions.
The cleaning liquid 3 is filled in the main body 100 to a certain level and stored therein so that the gas 2 introduced from the outside is mixed with the cleaning liquid 3, Can be removed. In this case, the level of the washing liquid 3 is lower than that of the later-described partition plate as shown in FIG. 2, and is formed at a position where the first and second blade portions 310 and 320 are locked.
In this case, the inside of the main body 100 is partitioned into the first to third spaces by the partition plate 140, and the base body 2 is divided into the first to third spaces So that the pollutants can be removed by mixing with the cleaning liquid.
More specifically, the partition plate 140 includes a partition 150, a first partition 160, and a second partition 170.
The partition 150 extends downward from the first sidewall 101 of the main body 100 toward the second sidewall 102 at an upper portion of the main body 100.
The first partition 160 extends downward from one side of the partition 150 so that the interior of the main body 100 is spaced apart from the first partition 160 on both sides of the first partition 160, (10) and a second space (20).
The second partition plate 170 extends downward from an end of the partition 150 so that the interior of the main body 100 is spaced apart from the second partition 170 by a second space (20) and a third space (30).
In this case, the first baffle portion is located below the first diaphragm 160 and the second blade portion 320 is positioned below the second diaphragm 170.
The gas 2 moved along the first diaphragm 160 is moved to the inside of the cleaning liquid by the first blade part 310 and the second space 20 in the first space 10, And the base 2 moved along the second diaphragm 170 is moved to the inside of the cleaning liquid by the second blade 320 and is moved in the second space 20 toward the third To the space (30).
At this time, the end portion of the first diaphragm 160 includes a first inlet portion 161 and a first guide portion 162.
The first inlet portion 161 extends along the first direction 5 adjacent to the first blade portion 310 so that the gas 2 flows into the inside of the cleaning liquid by the first inlet portion 161 . That is, the first inlet portion 161 is convex toward the first blade portion 310 so that the gas 2 introduced into the first space 10 flows into the first blade portion 310, To be moved to the place where it is located.
Accordingly, the base body 2, which is moved to a position adjacent to the first blade 310, is dispersed into the cleaning liquid by the rotation of the first blade 310, Is mixed with the micro bubble (4) generated by the micro bubble generator (200).
In this case, the base body 2 which has not been introduced into the washing liquid or the base body 2 which flows into the inside of the washing liquid and then flows out to the outside is introduced into the second space 20 by the first guiding portion 162 Movement is induced. That is, the first guiding portion 162 extends along the second direction 7 and extends upwardly as shown in FIG. 1 to extend into the interior of the cleaning liquid, So that the gas 2 flowing out to the outside is moved to the second space 20.
The first shielding plate 410 and the first guide plate 510 are installed adjacent to the first blade 310.
As shown in the figure, the first blocking guide plate 410 is located inside the cleaning liquid and is formed in a letter shape. Thus, the base 2 moved to the inside of the cleaning liquid along the first guiding portion 162 is blocked from moving upward by the first blocking guide plate 410 so that the base body 2 is prevented from moving to the cleaning liquid Is more effectively mixed with the micro bubble 4 in the inside of the micro bubble 4.
The first induction guide plate 510 is positioned to face the first induction section 162 and is concave toward the first induction section 162 so that the second induction guide plate 510 can be moved along the first induction section 162, And serves to guide the base body 2 from which the movement is induced to the space 20.
The first blocking wall 610 extends vertically from the bottom surface of the main body 100 so as to be bent so that the rear end thereof is directed in the second direction 7. Accordingly, a part of the base 2 which is guided to the second space 20 is blocked from moving upward by the end of the first blocking wall 610, and the first blocking wall 610, And is lowered into the inside of the cleaning liquid.
However, the base 2, which is not blocked by the first blocking wall 610, is moved upward from the inside of the main body 100, and is continuously moved while the partition 150 extending obliquely downward, The second diaphragm 170 extends in the downward direction.
At this time, the end portion of the second diaphragm 170 includes a second inlet portion 171 and a second guide portion 172.
The second inlet portion 171 extends along the first direction adjacent to the second blade portion 320 so that the gas 2 is moved into the cleaning liquid by the second inlet portion 171 . That is, the second inflow portion 171 is convex toward the second blade portion 320, so that the base body 2 introduced into the second space 20 is formed in the second blade portion 320, To be moved to the place where it is located.
Accordingly, the base body 2, which is moved to a position adjacent to the second blade 320, is dispersed into the cleaning liquid by the rotation of the second blade 320, Is mixed with the micro bubble (4) generated by the micro bubble generator (200).
In this case, the base body 2, which has not been introduced into the cleaning liquid, or the base body 2 which flows into the inside of the cleaning liquid and then flows out to the outside, is guided to the third space 30 by the second guiding portion 172 Movement is induced. In other words, the second guiding portion 172 extends along the second direction 7 and extends upwardly as shown in FIG. 1 to extend into the interior of the washer fluid 2 or the inside of the washer fluid, And then the gas 2 flowing out to the outside is moved to the third space 30.
Meanwhile, a second blocking guide plate 420 and a second guide plate 520 are installed adjacent to the second blade 320.
The second shielding guide plate 420 has the same shape as the first shielding guide plate 410 and the second guide guide plate 520 has the same shape as the first guide guide plate 510.
That is, the second shielding guide plate 420 is formed in the inside of the cleaning liquid and is formed in a letter shape, and the second guide plate 520 is positioned to face the second guide portion 172 And is formed in a concave shape toward the second induction part 172. [
Thus, the base 2 moved to the inside of the cleaning liquid along the second guide portion 172 is blocked from moving upward by the second blocking guide plate 420, Is more effectively mixed with the micro bubble 4 in the inside of the micro bubble 4.
The base 2 which is guided to the third space 30 along the second guiding portion 172 is guided by the second guiding guide plate 520 and is effectively guided into the third space 30 .
The second blocking wall 620 is formed in the third space 30 as shown in the figure and the first blocking wall 620 extends from one side of the second side wall 102 of the main body 100 toward the first side wall 101 As shown in Fig. Accordingly, a part of the base 2 which is guided to move into the third space 30 is blocked from moving upward by the second blocking wall 620 and collides with the second blocking wall 620 And falls again into the inside of the cleaning liquid.
However, the base 2, which is not blocked by the second blocking wall 620, is moved upward from the inside of the main body 100, and the electrostatic charge removing unit 700, which is formed on the upper end of the main body 100, Collecting. The configuration of the electrostatic canceller 700 will be described later.
2 and 3, the first blade portion 310 or the second blade portion 320 includes a body portion 330 and a plurality of blades 340.
The body portion 330 is formed in a cylindrical shape extending in one direction and can be rotated by the rotation shaft through a central portion passing through the rotation shaft. The blades 340 are fixed to the outer periphery of the body portion 330, Can be rotated together.
In this case, the blades 340 extend in the longitudinal direction of the body 330 at the outer periphery of the body 330 and extend in the direction toward the outside from the outer periphery of the body 330 , And the tip is formed in a pointed shape.
A plurality of fixing members 350 for fixing the blades 340 are formed on the outer circumference of the body 330 so that the blades 340 are fixed to the outer circumference of the body 330 May be formed.
The blades 340 may be formed of a flexible material such as a rubber material so that when the body 330 rotates in one direction inside the cleaning liquid, So that the base body 2 can be more effectively introduced into the inside of the cleaning liquid.
Meanwhile, the micro bubble generator 200 is positioned at the lower end of the main body 100 at the portion filled with the cleaning liquid. The micro bubble generator 200 may generate micro bubbles 4 by applying pressure to the cleaning liquid.
In this case, the micro bubble generator 200 includes compressed air providing means 210 and first and second micro bubble generating means 220 and 230 as shown in FIG.
The compressed air supply means 210 extends in one direction through the one side of the lower end of the first sidewall 101 of the main body 100 to extend the inflowing compressed air into the first and second microbubbles To the generating means (200, 230).
The first and second micro bubble generating units 220 and 230 extend vertically through the upper end of the compressed air providing unit 210 and are spaced apart from each other by a predetermined distance. Each of the first and second micro bubble generating units 220 and 230 generates micro bubbles 4 by discharging the compressed air supplied to the compressed air providing unit 210 from the inside of the cleaning liquid.
In this case, as shown in the figure, the first blade unit 310 is positioned above the first micro bubble generator 220 and the second blade unit 320 is disposed above the second micro bubble generator 230. [ The first and second micro bubble generating units 220 and 230 discharge the compressed air toward each of the first and second blade units 310 and 320 to generate the micro bubble 4 .
Accordingly, the base body 2 introduced into the cleaning liquid by the first and second blade portions 310 and 320 adjacent to the first and second blade portions 310 and 320, The pollutants contained in the gas 2 are removed while being mixed with the gas 4.
As described above, when the pollutants contained in the gas 2 are mixed with the microbubbles 4 in the cleaning liquid, the pollutants removed are formed adjacent to the bottom surface of the main body 100 And may be discharged to the outside through the slurry discharging unit 800.
The slurry discharge unit 800 includes a pipe 810 passing through the first and second sidewalls 101 and 102 at the bottom of the main body 100 and a pipe 810 through which the pipe 810 is opened / And a valve 820 for adjusting the pressure of the fluid. Thus, the discharge of the pollutant can be controlled by controlling the opening and closing of the pipe 810 through the control of the valve 820.
The pollutants discharged through the above mechanism may be pollutants of coarse particles having a relatively large particle size.
As described above, the base body 2, in which the contaminants are not removed in the third space 30, is moved upward and is collected by the electrostatic precipitator 700 located at the upper end of the main body 100, Contaminants are removed. In addition, the contaminant removed through it may be a relatively fine particle contaminant.
The electrostatic precipitator 700 includes first and second mesh portions 710 and 720 and a demister 730 as shown in FIG.
In this case, the electrostatic canceller 700 shown in FIG. 4 is one unit for convenience of description. A plurality of units are arranged in the horizontal direction in FIG. 4, So that the electrostatic charge removing unit 700 is formed.
Each of the first and second mesh portions 710 and 720 is made of a metal wire and is connected to a power supply portion 740 as shown in the figure. When power is supplied from the power supply unit 740, an electrostatic force is generated in each of the first and second mesh units 710 and 720 and the first and second mesh units 710 and 720 are moved along the first and second mesh units 710 and 720 due to the electrostatic force. As shown by the arrows, contaminants composed of ultrafine particles contained in the gas 2 moving in the upward direction are collected and removed by the first and second mesh portions 710 and 720.
The first and second mesh portions 710 and 720 are fixed to the first and second frames 751 and 752 at both ends of the first and second mesh portions 710 and 720, 1 and the second mesh portions 710 and 720, and both end portions thereof are fixed to the first and second frames 751 and 752.
Thus, when power is supplied to the first and second mesh portions 710 and 720, power can be supplied to the demister 730 through the first and second frames 751 and 752 The demister 730 also generates an electrostatic force, so that contaminants, moisture, and the like, which are ultrafine particles contained in the base 2, can be collected and removed by the demister 730.
At this time, the demister 730 is formed by vertically arranging a plurality of 'X' shaped metal wires, thereby generating the electrostatic force when the power is supplied, thereby removing contaminants contained in the base 2 can do.
As described above, the substrate 2 from which the contaminants are removed by the electrostatic precipitator 700 is moved upward and discharged to the outside through the gas discharging unit 120 formed at the upper end of the main body 100. [
In this case, although the gas discharging unit 120 is formed at the upper end of the main body 100, the gas discharging unit 120 may be installed at a position adjacent to the electrostatic precipitator 700 in the main body 100.
According to the embodiments of the present invention, the interior of the main body is partitioned into three spaces through the partition portion, and the gas moves sequentially through the respective spaces, thereby increasing the number of contact with the cleaning liquid and increasing the contact area. The removal efficiency can be improved.
Particularly, the gas is guided to move in the direction toward the partition walls through the partition portion including the plurality of diaphragms, and the gas is caused to collide against the partition walls, thereby allowing the gas to flow into the cleaning liquid. Accordingly, The pollutants can be effectively removed.
Further, since the plurality of blades of the blade portion rotating in the cleaning liquid are made of a rubber material, when the body of the blade portion rotates, the blades can be bent and rotated in the rotating direction, so that the rotating force of the blade portion can be improved.
Further, the gas that has not been removed through the cleaning liquid is collected through the static eliminator including the mesh portions and the demister, thereby removing the contaminants of the fine particles contained in the contaminants contained in the gas, thereby remarkably increasing the contaminant removal efficiency .
