The odor absorption capacity of the exhaust gas treatment device is enhanced by passing through the specific exhaust gas flow direction described above.

In detail, the partition 5 has a first side 51 and a second side 52. The partition 5 is connected to the top 1a of the body 1 by the first side 51. The spray space 131 and the defogging space 133 are formed on the processing space 13 , and the sprayer 2 is disposed in the spray space 131 , and the mist removing member 4 and the activated carbon filter 3 are disposed in the defogging space 133 . The spray space 131 is in communication with the air inlet 11 , and the mist removal space 133 is in communication with the discharge port 12 . In addition, the partition plate 5 forms the bypass space 132 between the second side 52 and the water tank 14 , and the bypass space 132 is disposed at a lower portion of the processing space 13 . By separating the partitions 5, on the one hand, the water sprayed by the sprayer 2 can be prevented from being sprayed onto the mist removing member 4, thereby increasing the effectiveness of the mist removing member 4 for reducing the humidity of the exhaust gas; The partition 5 The exhaust gas having high humidity after being washed by the atomizer 2 can be temporarily blocked from directly reaching the mist removing member 4.

More specifically, the exhaust gas flows in the spray space 131, the bypass space 132, and the defogging space in the first exhaust gas flow direction D1, the second exhaust gas flow direction D2, and the third exhaust gas flow direction D3, respectively. 133, and the first exhaust gas flow direction D1, the second exhaust gas flow direction D2, and the third exhaust gas flow direction D3 are different. Therefore, if the exhaust gas is to be sequentially passed through the sprayer 2 in the processing space 13, After the treatment of the mist removing member 4 and the activated carbon filter 3, the exhaust gas flowing in the spray space 131 in the first exhaust gas flow direction D1 must be diverted to bypass the partition 5 and the second exhaust gas.

During the process, part of the moisture contained in the exhaust gas is condensed on the partition 5 or is balanced with the relatively dry gas in the bypass space 132 to reach the mist removing member 4 . Before, you can reduce the moisture in the exhaust gas first. the amount.

Continuing to refer to FIG. 2, the exhaust gas treatment device of the present invention further includes a separation filter layer S located in the processing space 13 and disposed below the nozzle 211, the separation filter layer S being One of the first separation filter layer S1 and the second separation filter layer S2 are stacked on each other, and the separation filter layer S temporarily stores the exhaust gas therein, and increases the contact between the water and the exhaust gas discharged from the nozzle 211. area. In detail, the first separation filter layer S1 and the second separation filter layer S2 are arranged by the same separation filter, and the separation filter of the first separation filter layer S1 and the second separation filter layer S2 The arrangement directions are different to form intricate holes together, thereby increasing the effect of mixing the exhaust gas with the water and liquid. In addition, the exhaust gas treatment device of the present invention further comprises a non-woven filter F or a metal filter (not shown), and the non-woven filter F or the metal filter is disposed on the activated carbon filter 3 and the The non-woven filter F and the metal filter are used to remove the particulate contaminants in the exhaust gas which is not completely washed, so that the content of the particulate contaminants in the exhaust gas is decreased. .

Referring to FIG. 3 again, the exhaust gas treatment method according to the exhaust gas treatment device of the present invention comprises: spraying a water liquid on the exhaust gas flowing in the first flow direction D1 to wash the particulate pollution in the exhaust gas. Turning the washed exhaust gas and flowing toward the mist removing member 4 in the second exhaust gas flow direction D2; causing the exhaust gas to reach the mist removing member 4 in a third exhaust gas flowing direction D3 to be lowered through the mist removing member 4 The humidity of the exhaust gas; and the low-humidity exhaust gas is passed through the activated carbon filter 3 to remove volatile organic gases and odors contained in the exhaust gas.

In detail, the discharge port 12 is connected to an air pump (not shown), and the exhaust gas flows from the air inlet 11 to the discharge port 12 under the action of the air pump. This is understood by those of ordinary skill in the art and will not be further described herein. When the exhaust gas enters the spray space 131 through the air inlet 11, the water liquid sprayed by the sprayer 2 is washed, so that the bulky particulate pollutant in the exhaust gas is pulled by the liquid liquid and falls on the In the sink 14 .

Then, since the body 1 is provided with the partition 5, the washed exhaust gas cannot directly reach the defogging space 133 from the spray space 131, and must pass through the bypass space 132 to flow to the mist removing member 4. Furthermore, when the exhaust gas enters the spray space 131 from the air inlet 11 and flows to the sprayer 2 to receive the washing of the water liquid, the exhaust gas flows from the top to the bottom in the first exhaust gas flow direction D1. Flowing in 131, however, if it is intended to sequentially flow the washed exhaust gas to the defogging member 4 and the activated carbon screen 3, the exhaust gas must be bottomed up in the third exhaust gas flow direction D3. The flow in the space 133 is different because the first exhaust gas flow direction D1 and the third exhaust gas flow direction D3 are different, thereby forcing the exhausted exhaust gas to pass through the bypass space 132 in the second flow direction D2. The defogging space 133 prevents the exhaust gas having high humidity from immediately contacting the mist removing member 4, and can have a sufficient time for the exhaust gas to remove part of the water contained in the bypass space 132 in the two steering processes and the bypass space 132. gas.

When the exhaust gas passes through the decanting space 132 to the demisting space 133 to contact the demisting member 4, the moisture contained in the exhaust gas is further condensed on the demisting member 4 to pass through the partitioning member 5. And the mist removing member 4, the humidity of the exhaust gas after washing is greatly reduced, so that the activity is subsequently reached The moisture content of the exhaust gas of the carbon filter 3 is low, and the fine pores of the activated carbon filter 3 are prevented from being blocked by water molecules, so that the service life of the activated carbon filter 3 can be prolonged and the cost of waste gas treatment can be saved.

In addition, when the water is sprayed on the exhaust gas, the exhaust gas can be simultaneously concentrated in the separation filter layer S to increase the contact area between the water and the exhaust gas, and the particulate pollutant in the exhaust gas is washed in the separation filter layer S. The granular contaminant can be largely settled into the water tank 14 by washing; in addition, in order to fully intercept the particulate contaminant in the exhaust gas not removed in the washing process, before the exhaust gas passes through the activated carbon filter 3, The particulate contaminant is further filtered through the non-woven filter F or the metal mesh to discharge the particulate exhaust, the VOCs with low VOCs content and no odor.

Furthermore, in order to improve the use efficiency of the water liquid and prevent unnecessary waste of water resources, the water liquid after washing the exhaust gas can be collected by the water tank 14 of the bottom 1b of the body 1, since the water tank 14 is connected to the sprayer 2 The water supply tank 22 is connected to each other. Therefore, under the operation of the motor 23, the water supply pipe 21 can extract the water liquid after the exhaust gas is exhausted, and then re-spray the exhaust gas through the nozzle 211, so that the water liquid can be repeatedly recycled. In order to achieve the effect of complying with environmental trends. In addition, when treating the odorous exhaust gas, the water liquid may further comprise a deodorizing liquid to increase the efficiency of the exhaust gas treating method of the present invention to eliminate the exhaust gas odor.

In summary, in the exhaust gas treatment device of the present invention, the separator 5 is disposed between the atomizer 2 and the mist removing member 4, so that the washed exhaust gas must be diverted from the first exhaust gas flow direction D1 to the second exhaust gas. The flow direction D2 flows in the bypass space 132, and then turns to the third exhaust gas flow direction D3 to reach the mist removing member 4, so that the exhaust gas reaches the mist removing member 4 by the atomizer 2, wherein The moisture contained therein is subjected to humidity balance by first condensing on the partition 5 or the dry air of the bypass space 132, thereby reducing the humidity of the washed exhaust gas to reduce the fine pores of the activated carbon filter 3 due to moisture blocking. The situation arises, thereby achieving the effect of maintaining the odor absorption performance of the exhaust gas treatment device.

In the exhaust gas treatment method of the present invention, the washed exhaust gas must be diverted twice, in which the humidity of the exhausted exhaust gas can be lowered, and the high-humidity exhaust gas is prevented from destroying the activated carbon filter 3 with high price, thereby reducing the replacement of the activity. The frequency of the carbon screen 3, in turn, achieves the effect of reducing the cost of the exhaust gas treatment process.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
