FIGS. 3 and 4 show the scrubber body 10 of the present invention in a rectangular shape, and FIG. 5 shows the scrubber body 10 of the present invention in a circular shape.

The scrubber body 10 shown in FIGS. 1 to 5 is provided with a filter member 20 composed of first to fourth filters 21 to 24 and first to fourth flow paths 41 to 44 And the swirling flow path 40 is provided.

The filter member 20 and the swirling flow passage 40 may be provided with a filter member 20 composed of two filters and a swirling flow passage 40 composed of two flow paths as required.

The filter member 20 and the swirling flow passage 40 may be provided with three filter members 20 and a swirling flow passage 40 formed of three flow paths.

These filter members 20 and the swirling flow passage 40 may be composed of two or more filter members 20 and a swirling flow passage 40, depending on the processing capacity of the scrubber body 10 or the like.

5, the filter member 20 includes a first filter 21 to a fourth filter 24, and the swirling flow path 40 distributes the malodor air. (41) to a fourth flow path (44) so as to make contact with each other.

The filter member 20 installed inside the scrubber body 10 shown in Fig. 5 can be installed in two or three or more and the swirling flow passage 40 can also be provided with two or three It is needless to say that they can be installed more than two.

Illustratively, the swirling flow passage 40 has four flow passages communicating with each other when the scrubber body 10 has a rectangular shape. When the scrubber main body 10 is triangular, three filter members 20 and three It is of course possible to provide the same number of filter members 20 and pivoting flow paths 40 as polygons in the case of a pentagon, a hexagon, an octagon, or the like.

1 to 4, the swirl flow passage 40 is formed with a plurality of manholes 19 formed in the inside of the scrubber body 10, and the manholes 19 are formed in the scrubber body 10, Or a polygon having the same shape as the flow path formed in the scrubber body 10.

The third flow path 43 is provided at a predetermined height lower than the upper end of the second flow path 22 and the fourth flow path 44 is provided at a predetermined height lower than the upper end of the third flow path 43.

As described above, the swirling flow path 40 is made to be stepped so that the moving speed (or pressure) of the stench air can be maintained. This is distributed while the odor air is moved along the swirling flow path (40). A part of the odor air flowing into the first flow path 41 is raised to the first filter 21 through the contact member 30 and the remaining odor air is moved to the second flow path 42.

A part of the odor air moved to the second flow path 42 is moved to the third flow path 43 while being raised to the second filter 22, 3 filter 23 and is moved to the fourth flow path 44. A part of the odor air moved to the fourth flow path 44 is raised to the fourth filter 24, To the first flow path (41).

The odor air is distributed along the respective swirling flow paths (40). That is, while the swirling flow path 40 is open to each other, a part of the odor air is raised through the filter member 20 to be uniformly distributed. The odor air that is raised by the filter member 20 is increased in contact with the cleaning liquid falling through the nozzle so as to increase the removal efficiency of the odor.

That is, since the odor air is not entirely moved up by the filter member 20 but is distributed and raised while being moved along the swirling flow passage 40, the amount of the odor air to be increased is larger than that of the rising odor air, The removal efficiency of the odor air is increased.

And odor air is prevented from remaining in the inside of the scrubber body 10 as the odor air is moved along the swirling flow path 40. That is, the malodorous air is moved upward along the first filter (21) and the second filter (40) while being moved along the swirling flow path (40).

FIG. 6 is a cross-sectional view showing a multi-stage washing and deodorizing apparatus using a reciprocating flow path contact according to a preferred embodiment of the present invention and a partially enlarged view of a contact member.

Fig. 6 (a) is a sectional view taken along the line A-A in Fig. 4, and Fig. 6 (b) is an enlarged view of the contact member 30 provided below the filter member 20.

As shown in FIG. 6 (a), a contact member 30 is provided on the lower side of the filter member 20 so as to be inclined at a predetermined angle. The contact member 30 is formed in a zigzag shape when viewed from the front.

A plurality of holes 31 are formed in the mountains and the valleys of the contact member 30 made of a zigzag shape. As shown in Fig. 6 (a), the hole 31 may be formed in a circular shape, or may have a rectangular shape as shown in Fig. 6 (b).

In addition, the hole 31 formed adjacent to the filter member 20 is formed to be small in size, and the hole 31 can be gradually increased in size as the filter member 20 moves away from the filter member 20.

As a result, a part of the odor air rises toward the filter member 20 while passing through the hole 31.

The holes 31 may be formed in the mountains and the valleys of the contact member 30, respectively, and the holes 31 may be formed in only one of the mountains and the valleys.

The malodor air passing through the holes 31 comes into contact with the cleaning liquid flowing down along the valleys of the contact members 30, thereby enhancing the removal efficiency of the malodorous air.

That is, a part of the odor air strikes the cleaning liquid, and the gas-liquid contact is made to remove the odor of the odor air, and the gas-liquid contact is again performed while passing through the filter member 20.

The odor air passing through the hole (31) is ejected at a high pressure and is contacted with a cleaning liquid falling through the second filter member (20). As the odor air passes through the fine holes 31 and is ejected, the odor air hits the cleaning liquid falling into the water droplets, thereby destroying the cleaning liquid.

That is, the odor air collides with the cleaning liquid, thereby breaking the water droplets of the cleaning liquid. Accordingly, the odor air increases the contact with the cleaning liquid and improves the deodorization efficiency of the odor contained in the odor air.

The contact member 30 is installed in the first flow path 41, the second flow path 42, the third flow path 43 and the fourth flow path 44, And is inclined at a predetermined angle so as to be positioned in the flowing direction.

As shown in FIG. 7, in the multi-stage washing and deodorizing apparatus using the circulating flow path contact according to the embodiment of the present invention, the filter member 20 and the contact member 30 may be spaced apart from each other by a predetermined height.

As shown in FIG. 7, the filter members 20 are stepped to have different heights, and the contact members 30 provided at the lower portions are spaced apart from each other by a predetermined height.

This is to allow odor air to pass through the contact member 30 to be diffused. That is, the stench air is passed through the narrow hole 31 of the contact member 30 and then spread over the upper side of the contact member 30 in order to enhance the odor removal efficiency of the stench air.

As shown in FIG. 8, the filter members 20 are installed at the same horizontal height, and the length of the contact members 30 is different, so that the flow path space of the swirling flow path 40 can be made different.

8, the filter member 20 is installed at the same height, and the length of the contact member 30 provided in the first flow path 41 is the shortest and the length of the contact member 30 provided in the second flow path 42 The length of the contact member 30 is set longer than the length of the contact member 30 of the first flow path 41.

The length of the contact member 30 provided on the third flow path 43 is longer than the length of the contact member 30 of the second flow path 42. The length of the contact member 30 provided on the fourth flow path 44, Is longer than the length of the contact member (30) of the third flow path (43).

By varying the length of the contact member 30 as described above, the volume (or volume) of the swirling flow passage 40 is divided differently so that odor air can flow through the first flow path 41, the second flow path 42, 43 and the fourth flow path 44 to be evenly distributed.

7 and 8, the filter member 20 and the contact member 30 are spaced apart from each other, so that the filter member 20 or the contact member 30 can be easily replaced can do.

As shown in Fig. 7, the filter member 20 is provided on the swirling flow passage 40 so as to be stepped at different heights, and the swirling flow passage 40 is provided with the filter member 20 at the same height And the volume (or volume) of the circulating flow path 40 are set to be different from each other by the contact members 30 having different lengths.

On the other hand, the swirling flow passage 40 can be provided with the filter member 20 spirally arranged in a stepped manner. That is, the swirling flow passage 40 is formed in a spiral shape so that the height of the swirling flow passage 40 from the inlet of the swirling flow passage 40 provided with the inlet pipe 11 to the end of the swirling flow passage 40 gradually increases Can be formed to be low.

By forming the swirling flow passage 40 in the spiral shape in this manner, the moving speed of the odor air moving along the swirling flow passage 40 can be maintained uniformly.

Next, a method of operating the multi-stage washing and deodorizing apparatus using the circulating flow path contact according to the preferred embodiment of the present invention will be described with reference to FIGS. 1 to 8. FIG.

As shown in FIGS. 1 to 8, the multi-stage washing and deodorizing apparatus using the circulating flow path contact of the present invention can remove the odor air generated from livestock, manure, wastewater treatment plant, sewage end treatment plant, landfill, So that it flows into the inflow pipe (11).

The malodor air is uniformly transferred to the inside of the scrubber body 10 through the inflow pipe 11 and the transferred malodor air sequentially moves along the swirling flow passage 40 formed in the lower portion of the scrubber body 10.

A contact member 30, which is inclined at a predetermined angle, is provided in the upper portion of the first flow path 41, and a first filter 21 is installed.

The odor air supplied to the first flow path (41) is ejected through the hole (31) of the contact member (30) provided at an inclined angle. Thus, the odor air passing through the hole 31 is ejected at a high pressure and strikes the cleaning liquid dropped through the first filter 21, and the cleaning liquid falling by the water droplet is broken by the ejected odor air.

As a result, the malodor air introduced into the inflow pipe 11 is removed by the cleaning liquid as the gas-liquid contact with the cleaning liquid is made.

The contact member 30 is provided at an angle to be inclined so as to enhance gas-liquid contact between the odor air and the cleaning liquid.

A part of the odor air supplied to the third flow path 43 collides with the cleaning liquid while passing through the hole 31 of the contact member 30 provided in the third flow path 23.

The odor air strikes against the droplet of the cleaning liquid, and is brought into vapor-liquid contact with the cleaning liquid. The odor air is converted into the purified air from which odor is removed, and the air moves upward toward the third filter 23 installed in the third flow path 43.

The malodor air supplied to the third flow path 43 and the fourth flow path 44 is the same as that of the first flow path 41 and the second flow path 42, so that a duplicate description will be omitted.

On the other hand, a part of the odor air moved to the fourth flow path 44 is moved to the first flow path 41 through the opening 45 communicated with the first flow path 41, The odor is removed.

Thus, the purified air raised to the upper portion of the filter member 20 is purified again by gas-liquid contact with the cleaning liquid sprayed from the nozzle.

The purified air raised to the upper portion of the scrubber main body 10 is moved to the demister filter 17 installed in a cylindrical shape and discharged to the outside through the exhaust port 16.

The air outlet 16 is maintained at a temperature lower than the internal temperature of the scrubber body 10 by the air cooler 18 so that the purified air is heated by the temperature difference between the inside of the scrubber body 10 and the exhaust port 16 So that it can be quickly discharged to the outside.

In addition, the demister filter 17 removes the moisture contained in the purified air, thereby further facilitating the movement of the purified air.
