[0040] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0041] Example 1

[0042] like Figures 1-14As shown, a device for treating malodorous exhaust gas for the disposal of dead animals comprises a spray tower 2 arranged on a frame 1, a filtering mechanism 3 arranged inside the spray tower 2 and used for purifying spray water, and a flushing mechanism 4 arranged on the frame 1 and used for cleaning filler balls;

[0043] The spray tower 2 includes a tower shell component 21 disposed on the frame 1, a spray component 22 disposed inside the tower shell component 21, and a filling component 23 disposed inside the tower shell component 21 and used for dynamically distributing filler balls;

[0044] The spray assembly 22 sprays water on the exhaust gas entering the tower shell assembly 21, and the packing balls provide a carrier for the exhaust gas rising in the tower shell assembly 21 to contact and react with the spray water. The filling assembly 23 drives the packing balls to move horizontally to change the vertical rising trajectory of the exhaust gas, increase the residence time of the exhaust gas, and discharge the packing balls to the flushing mechanism 4. The flushing mechanism 4 cleans the surface of the packing balls and returns the packing balls to the spray assembly 22 for reuse. The filtering mechanism 3 filters and purifies the spray water at the bottom of the spray tower 2, and stirs the liquid surface to splash water to pre-treat the exhaust gas discharged downward to the liquid surface.

[0045] It should be noted that the specific process for treating malodorous tail gas is as follows: first, the mixed gas containing H2S and NH3 is first filtered with a dust removal filter bag to remove impurities in the tail gas; then, a spray tower with dilute sulfuric acid (diluted with waste sulfuric acid used or produced in the chemical industry) as a scrubbing liquid is introduced, and NH3 in the mixed gas can be removed through secondary scrubbing, and (NH4)2SO4 is produced from the primary tower (the scrubbing liquid of the secondary tower can be used as a supplementary scrubbing liquid for the primary tower after reaching a certain concentration). After (NH4)2SO4 reaches a certain concentration, it is concentrated in a crystallization kettle, and then centrifuged and dried to obtain (NH4)2SO4. 4 products; then, the gas absorbed by the above-mentioned secondary absorption tower is introduced into a spray tower using NaOH solution as a scrubbing liquid. After the secondary scrubbing, H2S can be removed, and Na2S is produced from the primary tower (after the scrubbing liquid in the secondary tower reaches a certain concentration, it can be used as a supplementary scrubbing liquid for the primary tower). After the Na2S reaches a certain concentration, it is sent to the regulating kettle, where the pH value is adjusted with NaOH. It is then sent to the concentration crystallization kettle, and then centrifuged and dried to obtain the Na2S product; finally, the gas after the above four spray scrubbings (if there is organic gas in the tail gas, it can be adsorbed on the secondary activated carbon) can be scrubbed in the primary water spray tower before meeting the emission standards. Process advantages: 1. Hydrogen sulfide will produce sulfur dioxide after combustion, which will cause emissions to fail to meet standards; 2. Waste sulfuric acid can be recycled point-to-point in accordance with the 2021 Hazardous Waste Management Regulations; 3. Ammonium sulfate (commonly known as ammonia fertilizer) is also produced during the treatment; 4. It not only harmlessly treats the odorous gases in the tail gas, but also brings benefits to the company in the treatment of hazardous waste.

[0046] It is worth mentioning that, in the present invention, the spray tower 2, the filtering mechanism 3 and the flushing mechanism 4 can be used as an integral device, and a plurality of such devices can be placed in parallel and connected to achieve the effect of four spray washing operations.

[0047] It should also be noted that the role of the horizontally moving packing balls is: on the one hand, it can not only change the vertical rising trajectory of the exhaust gas and increase the residence time of the exhaust gas; on the other hand, it can also increase the reaction contact area between the packing balls and the exhaust gas, thereby improving the exhaust gas purification effect. The reason is that when the traditional statically placed packing balls encounter vertically rising exhaust gas, the surface of the packing balls that is perpendicular to or at an angle to the rising direction of the exhaust gas can contact the exhaust gas, but the surface of the packing balls that is parallel to the rising direction of the exhaust gas cannot contact the exhaust gas, and the spray water on the parallel surface will have no purification effect. When the packing balls move horizontally, the surface of the packing balls that is parallel to the rising direction of the exhaust gas will cross the rising exhaust gas, so that the spray water on the parallel surface can contact the rising exhaust gas, thereby increasing the reaction contact area between the packing balls and the exhaust gas.

[0048] In this embodiment, by cooperating with the setting of the filling assembly 23 and the flushing mechanism 4, on the one hand, the packing balls can be dynamically arranged, the upward flow path of the exhaust gas can be changed, the residence time of the exhaust gas can be increased, the reaction contact surface between the packing balls and the exhaust gas can be increased, and the exhaust gas can be ensured to fully react with the spray water, thereby improving the purification efficiency of the exhaust gas; on the other hand, the stains on the surface of the packing balls can be automatically transferred and flushed, the cleanliness of the surface of the packing balls can be maintained, and a large amount of stains can be prevented from being attached to the surface of the packing balls, which affects the working effect of the packing balls, thereby increasing the service life of the packing balls.

[0049] In detail, the exhaust gas is discharged from the exhaust gas inlet pipe 213 to the liquid surface of the intermediate water chamber 212 at the bottom of the tower body 211. The water splashed from the liquid surface pre-purifies the exhaust gas and cleans the particulate matter in the exhaust gas. At the same time, the liquid surface rebounds the exhaust gas to quickly fill the entire intermediate water chamber 212. Then, the exhaust gas in the intermediate water chamber 212 is evenly distributed and rises. The rising exhaust gas passes through the first spray chamber 214 and the second spray chamber 215 in turn for purification. The spray assembly 22 sprays the spray water containing the purification liquid from the top of the first spray chamber 214 and the top of the second spray chamber 215 The water distributor 222 sprays downward to the surface of the packing balls, the transfer unit 232 drives the packing balls to move horizontally to change the vertical rising trajectory of the exhaust gas, increase the residence time of the exhaust gas, and discharge the packing balls in the second spray chamber 215 into the first spray chamber 214, and then the packing balls in the first spray chamber 214 are The balls are discharged into the cleaning component 41. At the same time, the support unit 231 replenishes the filler balls on the transfer unit 232. Then, the cleaning component 41 uses the spray water in the circulating water tank 221 to rinse the stains on the surface of the filler balls. The flushing waste water flows back to the middle water chamber 212. The return component 43 sends the rinsed filler balls back to the second spray chamber 215 to achieve the effect of recycling the filler balls. Then, the purified exhaust gas passes through the demister 216 to remove the water mist and is discharged from the exhaust gas outlet pipe 217. Therefore, the spray waste water falling from the first spray chamber 214 and the second spray chamber 215 enters the middle water chamber 212. The filtering mechanism 3 filters out impurities in the spray waste water, cleans and collects the filtered impurities, and at the same time stirs the liquid surface of the middle water chamber 212 to splash water to pre-treat the exhaust gas discharged downward to the liquid surface. The filtered spray waste water flows back to the circulating water tank 221 for continued use.

[0050] Further, if Figure 1-Figure 4 As shown, the tower shell assembly 21 includes a tower body 211 arranged on the frame 1, and a medium water chamber 212, an exhaust gas inlet pipe 213, a first spray chamber 214, a second spray chamber 215, a demister 216, and an exhaust gas outlet pipe 217 arranged inside the tower body 211 from bottom to top.

[0051] It should be noted that the outlet end of the tail gas inlet pipe 213 is arranged downward, so that the tail gas is discharged from the tail gas inlet pipe 213 toward the liquid surface of the intermediate water chamber 212 .

[0052] It should also be noted that the demister 216 adopts the demister 216 used in the existing spray tower, which is mainly used to remove water mist in the purified exhaust gas.

[0053] In this embodiment, the tower shell assembly 21 is provided so that the tail gas is purified and then discharged from bottom to top.

[0054] In detail, the exhaust gas is discharged from the exhaust gas inlet pipe 213 toward the liquid level of the intermediate water chamber 212, and the exhaust gas in the intermediate water chamber 212 is evenly distributed and rises. The rising exhaust gas passes through the first spray chamber 214 and the second spray chamber 215 in turn for purification. The purified exhaust gas passes through the demister 216 to remove water mist and is discharged from the exhaust gas outlet pipe 217.

[0055] Further, if Figure 1-Figure 4 As shown, the spray assembly 22 includes a circulating water tank 221 arranged on the frame 1 and connected to the intermediate water chamber 212 through a connecting pipe, two groups of water distributors 222 respectively arranged on the top of the first spray chamber 214 and the top of the second spray chamber 215 and both connected to the circulating water tank 221 through connecting pipes, a water pump 223 arranged on the circulating water tank 221, a dosing barrel 224 arranged on the circulating water tank 221, and a water supply pipe arranged on the circulating water tank 221.

[0056] It should be noted that the structure and function of the water distributor 222 are both existing technologies and will not be repeated here. Several groups of spray heads are provided at the bottom of the water distributor 222, and the water pump 223 draws the spray water in the circulating water tank 221 to the water distributor 222.

[0057] It is worth mentioning that the purification liquid is added into the circulating water tank 221 from the dosing barrel 224. In this embodiment, the purification liquid can be dilute sulfuric acid or NaOH solution.

[0058] In this embodiment, the spray assembly 22 and the tower shell assembly 21 cooperate to pump the scrubbing liquid containing the purification liquid into the first spray chamber 214 and the second spray chamber 215 , and the spray water is recovered for recycling.

[0059] In detail, the purified liquid is poured into the circulating water tank 221 from the dosing barrel 224, and the water pump 223 pumps the spray water in the circulating water tank 221 to the water distributor 222 at the top of the first spray chamber 214 and the second spray chamber 215. The water distributor 222 sprays the spray water through the spray head, and the spray waste water collected in the intermediate water chamber 212 flows back to the circulating water tank 221.

[0060] Further, if Figure 2 and Figure 4-Figure 8 As shown, the filling assembly 23 is divided into two groups and is respectively arranged inside the first spray chamber 214 and the second spray chamber 215. It includes a support unit 231 arranged at the bottom of the first spray chamber 214 and used to place the filling balls, and a transfer unit 232 arranged at the bottom of the first spray chamber 214 and used to drive the filling balls to move horizontally.

[0061] The transfer unit 232 includes two groups of semicircular outer edge boxes 2321 symmetrically arranged on the side walls of the first spray chamber 214, a rotating wheel 2322 rotatably arranged inside the semicircular outer edge box 2321, a conveyor belt 2323 arranged between the two rotating wheels 2322, a first orifice plate 2324 horizontally arranged on the conveyor belt 2323 and attached to the inner wall of the first spray chamber 214 and the inner wall of the semicircular outer edge box 2321, and several groups of partitions 2325 arranged on the first orifice plate 2324. The dry group includes a lower row of doors 2326 hingedly arranged on the first orifice plate 2324 and respectively located between two adjacent partitions 2325, two groups of first support strips 2327 symmetrically arranged at the bottom of the first spray chamber 214 and used to support the closure of the lower row of doors 2326, two groups of second support strips 2328 symmetrically arranged at the bottom of the first spray chamber 214 and used to support the conveyor belt 2323, and a first driving member arranged on the semicircular outer edge box 2321 and used to drive the wheel 2322.

[0062] It should be noted that the first driving member adopts an existing stepping motor, which is fixedly installed on the top of the semicircular outer box 2321 and is gap-embedded in the top of the rotating wheel 2322 to achieve the effect of driving the rotating wheel 2322.

[0063] It is worth mentioning that the first orifice plate 2324 is made of slightly deformable hard rubber material, and can be slightly deformed when the first orifice plate 2324 passes through the interior of the semicircular outer edge box 2321.

[0064] It should also be noted that when the lower row door 2326 on the first orifice plate 2324 passes through a semicircular outer edge box 2321 with an open lower end, the hinged lower row door 2326 loses the support of the first support strip 2327 and rotates downward to open, causing the filler balls on the lower row door 2326 to fall into the second channel 422, thereby discharging the filler balls. When the lower row door 2326 on the first orifice plate 2324 leaves the semicircular outer edge box 2321, the lower row door 2326 is supported by the end of the first support strip 2327 and gradually closes upward, continuing to carry new filler balls to move.

[0065] In this embodiment, by cooperating with the transfer unit 232 and the spray assembly 22, the filler balls can be dynamically arranged, the upward flow path of the exhaust gas can be changed, the residence time of the exhaust gas can be increased, the reaction contact surface between the filler balls and the exhaust gas can be increased, and the exhaust gas can be fully reacted with the spray water, thereby improving the purification efficiency of the exhaust gas.

[0066] In detail, the first driving member drives the conveyor belt 2323 with the first orifice plate 2324 through the rotating wheel 2322, and the first orifice plate 2324 carries the filler balls and moves horizontally through the partition 2325. After the lower row door 2326 on the first orifice plate 2324 passes through a semicircular outer edge box 2321 with an open lower end, the lower row door 2326 rotates downward to open and discharge the filler balls. When the lower row door 2326 on the first orifice plate 2324 leaves the semicircular outer edge box 2321, the lower row door 2326 gradually closes upward under the support of the end of the first support strip 2327, and continues to carry new filler balls to move.

[0067] Further, if Figure 4-Figure 8 As shown, the support unit 231 includes two groups of vertical plates 2311 that are respectively slidably set on the two second support strips 2328 and flush with the height of the conveyor belt 2323, two groups of second orifice plates 2312 that are respectively inclined and fixedly connected to the top of the two vertical plates 2311, two groups of side plates 2313 that are symmetrically set on the sides of the second orifice plates 2312, a first elastic member 2314 set between the side plate 2313 and the inner wall of the first spray chamber 214, a buffer corrugated plate 2315 set between the side plate 2313 and the inner wall of the first spray chamber 214, a connecting plate set between the two vertical plates 2311, a push rod 2316 set on the connecting plate, and several groups of arc grooves 2317 set on the side surface of one of the rotating wheels 2322 and used to drive the push rod 2316 to move the second orifice plate 2312 back and forth horizontally.

[0068] It's worth noting that the buffer corrugated plate 2315 is sealed to close the gap between the second orifice plate 2312 and the inner wall of the first spray chamber 214. In order for the vertical plate 2311 to move horizontally with the second orifice plate 2312, a gap must remain between the vertical plate 2311 and the inner wall of the first spray chamber 214. If this gap is not sealed, the exhaust gas will be discharged directly upward through the gap, resulting in some exhaust gas not being purified. Therefore, the buffer corrugated plate 2315 is required to close this gap.

[0069] It should be noted that the filler balls stacked on the second orifice plate 2312 also have a purification effect on the rising exhaust gas.

[0070] It should also be noted that a wear-resistant friction layer is provided on the upper surface of the second orifice plate 2312. During the reciprocating horizontal movement of the second orifice plate 2312, the second orifice plate 2312 can drive the filler balls in the lower layer to rotate, thereby disturbing the rising exhaust gas, increasing the contact area between the filler balls and the exhaust gas, increasing the residence time of the exhaust gas, and fully purifying the exhaust gas.

[0071] In this embodiment, through the cooperation of the support unit 231 and the transfer unit 232, on the one hand, it can support the stacking of filler balls and automatically replenish filler balls to the first orifice plates 2324 on both sides, ensuring that the first orifice plates 2324 are always loaded with filler balls, preventing the filler balls on the second orifice plates 2312 from staying still; on the other hand, it can drive the filler balls in the lower layer to rotate, thereby disturbing the rising exhaust gas, increasing the contact area between the filler balls and the exhaust gas, increasing the residence time of the exhaust gas, and fully purifying the exhaust gas.

[0072] In detail, the filler balls are stacked on the second orifice plate 2312. In the process of the first driving member driving the conveyor belt 2323 to carry the first orifice plate 2324 through the rotary wheel 2322, the arc-shaped groove 2317 on one of the rotary wheels 2322 repeatedly drives the support rod 2316 to move back and forth horizontally on the second support strip 2328 through the connecting plate, so that the vertical plate 2311 carries the second orifice plate 2312 to move back and forth horizontally, and the second orifice plate 2312 drives the filler balls in the lower layer to rotate, thereby disturbing the rising exhaust gas. At the same time, due to the reciprocating horizontal movement of the second orifice plate 2312, the filler balls stacked on the second orifice plate 2312 roll to both sides and fall onto the first orifice plate 2324, thereby achieving the effect of automatically replenishing the filler balls on the first orifice plates 2324 on both sides.

[0073] Further, if Figure 1-Figure 4 and Figures 9-11 As shown, the flushing mechanism 4 includes a cleaning assembly 41 provided on the frame 1, a material transfer assembly 42 provided on the tower body 211 and used to transfer the filler balls from the tower body 211 to the cleaning assembly 41, and a return assembly 43 provided on the cleaning assembly 41 and used to move the flushed filler balls back into the tower body 211.

[0074] The cleaning assembly 41 includes an elliptical vertical box 411 provided on the frame 1, a conveyor belt 412 rotatably provided inside the elliptical vertical box 411, a plurality of drain plates 413 provided on the conveyor belt 412 and in contact with the inner wall of the elliptical vertical box 411, a receiving box 414 provided on the side wall of the elliptical vertical box 411, a plurality of high-pressure nozzles 415 provided inside the receiving box 414 and used for flushing the filler balls between two adjacent drain plates 413, a return pipe 416 provided on the side wall of the elliptical vertical box 411 and connected to the interior of the intermediate water chamber 212, and a second driving member provided on the frame 1 and used for driving the conveyor belt 412;

[0075] The material transfer assembly 42 includes an opening opened in the semicircular outer edge box 2321, a first channel 421 arranged at the bottom of the semicircular outer edge box 2321 located on the outer wall of the second spray chamber 215 and used to guide the filler balls discharged from the second spray chamber 215 to the first spray chamber 214, a second channel 422 arranged at the bottom of the semicircular outer edge box 2321 located on the outer wall of the first spray chamber 214 and used to guide the filler balls discharged from the first spray chamber 214 to the elliptical vertical box 411, and a third channel 423 arranged on the side wall of the elliptical vertical box 411 and used to guide the rinsed filler balls to the second spray chamber 215.

[0076] It should be noted that the water pump 223 sucks the spray water in the circulating water tank 221 to the high-pressure nozzle 415. The wastewater generated by the high-pressure nozzle 415 for flushing the packing balls gathers at the bottom of the elliptical vertical box 411, and the liquid level is flush with the top of the second channel 422. The liquid level can water seal the second channel 422 to prevent the exhaust gas in the first spray chamber 214 from entering the interior of the elliptical vertical box 411 from the second channel 422, and then entering the second spray chamber 215 from the third channel 423 and being directly discharged.

[0077] It is worth mentioning that the rising exhaust gas passes through the first spray chamber 214 and the second spray chamber 215 successively. Therefore, the packing balls in the second spray chamber 215 are cleaner than the packing balls in the first spray chamber 214. Therefore, the packing balls in the second spray chamber 215 can be transferred to the first spray chamber 214 for continued use.

[0078] It should also be noted that the second driving member adopts an existing stepping motor.

[0079] In this embodiment, the cleaning component 41 and the material moving component 42 cooperate to automatically flush the filler balls, thereby recycling the filler balls.

[0080] In detail, the filler balls in the second spray chamber 215 are transferred from the first channel 421 to the first spray chamber 214, and the filler balls in the first spray chamber 214 are transferred from the second channel 422 to the elliptical vertical box 411. The second driving member drives the conveyor belt 412 to move intermittently with the filler balls through the drain plate 413. When the filler balls rise to the position of the receiving box 414, the conveyor belt stops operating. The high-pressure nozzle 415 flushes the filler balls on the drain plate 413. The waste water gathers from the drain plate 413 to the bottom of the elliptical vertical box 411, and then flows back to the intermediate water chamber 212 from the return pipe 416 for filtration.

[0081] Further, if Figure 2 、 Figure 4 and Figures 9-11As shown, the return assembly 43 includes several groups of sliding rods 431 that pass through and are slidably arranged on the conveyor belt 412 and are respectively located between two adjacent drain plates 413, a push plate 432 that is arranged at one end of the sliding rod 431 and is used to push the flushed filler balls into the third channel 423, a second elastic member 433 that is arranged between the other end of the sliding rod 431 and the conveyor belt 412, a sliding hole opened on the elliptical vertical box 411, a dial plate 434 that is slidably arranged on the sliding hole and is used to move the sliding rod 431, and a hydraulic member 435 that is arranged on the outer wall of the elliptical vertical box 411 and is used to drive the dial plate 434.

[0082] In this embodiment, the return assembly 43 and the cleaning assembly 41 cooperate to return the rinsed filler balls to the second spray chamber 215 for recycling.

[0083] In detail, when the filler balls rise to the position of the holding box 414 and stop, the push plate 432 stops at the port position of the third channel 423, and one end of the slide rod 431 stops at the position of the dial plate 434. The hydraulic component 435 drives the slide rod 431 to move horizontally with the push plate 432 through the dial plate 434, so that the push plate 432 sends the filler balls rinsed on the drain plate 413 back to the second spray chamber 215.

[0084] Further, if Figure 2 、 Figure 4 and Figure 12-14 As shown, the filtering mechanism 3 includes a filter plate 31 arranged inside the intermediate water chamber 212 and located below the return water pipe 416, several groups of rollers 32 arranged in parallel and rotating inside the intermediate water chamber 212 and located above the filter plate 31, a suspension rod 33 that passes through and is lifted and lowered in the middle part of the roller 32, a cleaning strip 34 arranged at one end of the suspension rod 33 and used to clean impurities on the filter plate 31, a third elastic member arranged between the other end of the suspension rod 33 and the outer peripheral wall of the roller 32, an impurity box 35 connected to the outer wall of the intermediate water chamber 212 and used to store impurities, and a third driving member arranged on the outer wall of the intermediate water chamber 212 and used to drive one of the rollers 32. Several groups of the rollers 32 work synchronously through a transmission method of belts and pulleys.

[0085] It should be noted that the third driving component adopts an existing stepping motor.

[0086] In this embodiment, by cooperating with the filter mechanism 3 and the tower shell assembly 21, on the one hand, impurities in the spray wastewater can be filtered out, the impurities entering the circulating water tank 221 can be reduced, the damage of impurities to the pump body and pipeline can be reduced, and the filtered impurities can be automatically cleaned and collected to prevent the filter plate 31 from being blocked; on the other hand, the liquid level of the intermediate water chamber 212 can be moved. Compared with the calm liquid level, the fluctuating liquid level and the splashing water have a larger contact area with the exhaust gas, so the exhaust gas can be pre-purified.

[0087] In detail, the spray wastewater treated by the filter plate 31 flows back to the circulating water tank 221, and impurities are trapped on the filter plate 31. The third driving member drives the roller 32 to work synchronously through the transmission method of the belt and pulley. The cleaning strips 34 on each roller 32 take turns to gradually clean the impurities on the filter plate 31 into the impurity box 35. At the same time, the cleaning strips 34 at one end and the other end of the boom 33 alternately move the liquid level.

[0088] Example 2

[0089] like Figure 15 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0090] Further, if Figure 15 As shown, the impurity box 35 is provided with a sealed slag discharge door 36 .

[0091] In this embodiment, the sealed slag discharge door 36 is provided to regularly clean out the impurities collected in the impurity box 35 .

[0092] Working process:

[0093] First, the exhaust gas is discharged from the exhaust gas inlet pipe 213 to the liquid surface of the intermediate water chamber 212 at the bottom of the tower body 211. The water splashed from the liquid surface pre-purifies the exhaust gas and cleans the particulate matter in the exhaust gas. At the same time, the exhaust gas rebounds from the liquid surface to quickly fill the entire intermediate water chamber 212. Then, the exhaust gas in the intermediate water chamber 212 is evenly distributed and rises. The rising exhaust gas passes through the first spray chamber 214 and the second spray chamber 215 in turn for purification. The spray assembly 22 sprays the spray water containing the purification liquid from the water distributor 222 at the top of the first spray chamber 214 and the top of the second spray chamber 215 to the surface of the packing balls respectively. The transfer unit 232 drives the packing balls to move horizontally to change the vertical rising trajectory of the exhaust gas, increase the residence time of the exhaust gas, and discharge the packing balls in the second spray chamber 215 into the first spray chamber 214, and then the packing balls in the first spray chamber 214 are The balls are discharged into the cleaning component 41. At the same time, the support unit 231 replenishes the filler balls on the transfer unit 232. Then, the cleaning component 41 uses the spray water in the circulating water tank 221 to rinse the stains on the surface of the filler balls. The flushing waste water flows back to the middle water chamber 212. The return component 43 sends the rinsed filler balls back to the second spray chamber 215 to achieve the effect of recycling the filler balls. Then, the purified exhaust gas passes through the demister 216 to remove the water mist and is discharged from the exhaust gas outlet pipe 217. Therefore, the spray waste water falling from the first spray chamber 214 and the second spray chamber 215 enters the middle water chamber 212. The filtering mechanism 3 filters out impurities in the spray waste water, cleans and collects the filtered impurities, and at the same time stirs the liquid surface of the middle water chamber 212 to splash water to pre-treat the exhaust gas discharged downward to the liquid surface. The filtered spray waste water flows back to the circulating water tank 221 for continued use.
