Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of industrial waste gas treatment, and particularly relates to an industrial waste gas treatment device and a method thereof. BACKGROUND

[0002] Industrial waste gas refers to various exhaust gas containing pollutants discharged into the air in the process of fuel combustion and production process in the factory area. The exhaust gas includes carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid lead mercury, beryllium compounds, smoke dust and production dust, which will pollute the air when discharged into the air. These substances enter the human body through different ways of respiratory tract, some of which directly cause harm, and some of which have accumulation effect, which will cause more serious harm to human health. Therefore, for some industrial waste gas, the dust particles need to be filtered, and the harmful components need to be absorbed by the chemical absorbent to realize the purification treatment of the industrial waste gas.

[0003] The inventor found that the existing industrial waste gas is easy to cause high impurity content in the treatment liquid (i.e. absorbent) when the industrial waste gas is treated, especially when the dust particle content in the waste gas is high. Thus, when the treatment liquid is circulated and sprayed, the impurities cannot be quickly and effectively separated from the treatment liquid, which is easy to cause the phenomenon of blockage, so that the treatment liquid cannot be fully and effectively sprayed and adsorbed when the waste gas is treated, which affects the overall waste gas treatment efficiency.

[0004] Therefore, the existing structure and defects are researched and improved, and the industrial waste gas treatment device and the method thereof are provided, so as to achieve the purpose of being more practical. SUMMARY

[0016] An industrial waste gas treatment method, using the aforementioned industrial waste gas treatment device, includes the following steps:

[0017] S1 starts the intake fan to send industrial waste gas into the treatment tower through the intake pipe. At the same time, it controls the drive mechanism to spray the treatment liquid at the bottom of the treatment tower into the treatment tower by spraying, so that the impurities and harmful substances in the industrial waste gas entering the treatment tower are contacted, adsorbed and separated by the treatment liquid.

[0018] S2 then controls the spray shaft to rotate, so that the spray pipes spray in a rotating manner, thereby making the treatment liquid more evenly distributed in the treatment tower and improving the treatment effect.

[0019] The gas adsorbed by the S3 spray is then adsorbed again by the adsorption packing material and discharged through the exhaust pipe.

[0020] Compared with the prior art, the present invention has the following technical effects:

[0021] The design of the spray pipe and spray shaft enables the spray pipe to rotate and spray through the rotation of the spray shaft, thereby making the spray distribution of the treatment liquid more uniform in the treatment tower. This effectively increases the contact probability between the treatment liquid and the industrial waste gas, and improves the overall treatment efficiency. The addition of adsorption packing can further improve the treatment efficiency of the waste gas through the re-adsorption of the adsorption packing.

[0022] The design of the circulation pipe and conveying mechanism enables the recycling of the treated liquid within the treatment tower, effectively reducing costs. The vertical design of the circulation pipe, combined with the filter holes, effectively prevents impurities from accumulating on the outside of the filter holes, thus preventing clogging. In addition, the scraper ring and scraper, through the up-and-down movement of the scraper ring and the scraper, can promptly scrape impurities from the surface of the filter holes downwards, allowing impurities to accumulate better at the bottom of the treatment tower, while ensuring the filtration efficiency of the filter holes and preventing clogging.

[0023] The fixed connection between the adjusting shaft and the adsorption packing ensures that the rotation of the spray shaft does not cause the adjusting shaft to rotate synchronously. This design allows the spray pipe to rotate while simultaneously driving the suction plate to rotate automatically around the adjusting shaft. Combined with the characteristics of the first reciprocating thread, this enables the suction plate to move up and down periodically. In conjunction with the first one-way inlet valve and the first one-way outlet valve, the up-and-down movement of the suction plate draws the treated liquid from the treatment tower into the suction tank, and then discharges it through the guide channel and transports it to the spray pipe. This design achieves both the rotational spraying of the spray pipe and the automatic suction and transport of the treated liquid, reducing the need for power equipment and lowering costs.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] Example 1, please refer to Figure 1 , Figure 2 and Figure 8 An industrial waste gas treatment device includes a treatment tower 1, an exhaust pipe 12 at the top of the treatment tower 1, an intake fan 2 on an intake pipe 11, an intake pipe 11 on one side of the bottom of the treatment tower 1, a treatment liquid stored at the bottom of the treatment tower 1, and a rotatable spray shaft 3 in the middle of the treatment tower 1. Multiple spray pipes 15 for spraying the treatment liquid are mounted on the spray shaft 3. Multiple vertical circulation pipes 16 are also located at the bottom of the treatment tower 1, each with multiple filter holes. A conveying mechanism is provided inside the treatment tower 1 to transport the filtered treatment liquid to the spray pipes 15. A vertically movable scraper ring 37 is also provided on the circulation pipe 16. Multiple retractable scrapers 374 are located inside the scraper ring 37 for scraping impurities from the surface of the filter holes. Adsorption packing 14 is also provided inside the treatment tower 1 for adsorption and separation of the gas after spray treatment. The spray pipes 15 are arranged in a staggered pattern.

[0043] The design of the spray pipe 15 and the spray shaft 3 enables the spray pipe 15 to rotate and spray through the rotation of the spray shaft 3, thereby making the treatment liquid more evenly distributed in the treatment tower 1, effectively increasing the contact probability between the treatment liquid and the industrial waste gas and improving the overall treatment efficiency; the addition of the adsorption packing 14 can further improve the treatment efficiency of the waste gas through the re-adsorption of the adsorption packing 14.

[0044] The design of the circulation pipe 16 and the conveying mechanism enables the recycling of the treatment liquid within the treatment tower 1, effectively reducing costs. The vertical design of the circulation pipe 16, combined with the filter holes, effectively prevents impurities from accumulating on the outside of the filter holes and thus prevents clogging. In addition, the scraper ring 37 and scraper 374, through the up-and-down movement of the scraper ring 37 and the scraper 374, can promptly scrape impurities from the surface of the filter holes downwards, allowing impurities to accumulate better at the bottom of the treatment tower 1, while ensuring the filtration efficiency of the filter holes and preventing clogging.

[0045] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5In this embodiment, the conveying mechanism includes a suction groove and a suction plate. An adjustment hole is provided in the middle of the spray shaft 3, and an adjustment shaft 31 is rotatably and sealingly connected within the adjustment hole. The upper end of the adjustment shaft 31 is fixedly connected to the frame at the bottom of the adsorption packing 14. A suction groove 32 is also provided inside the spray shaft 3, and a sliding and sealingly connected suction plate 321 is provided within the suction groove 32. The adjustment shaft 31 moves through the suction plate 321, and a first reciprocating thread 311 is provided on the adjustment shaft 31 to match and connect with the suction plate 321. The bottom of the suction groove 32... The system is provided with multiple water inlet holes 323 connected to the circulation pipe 16. A first one-way water inlet valve 322 is provided in the water inlet hole 323. A guide groove 312 is provided in the regulating shaft 31. Multiple water outlet grooves 314 connected to the guide groove 312 are provided at the bottom of the regulating shaft 31. A first one-way drain valve 313 is provided in the water outlet groove 314. A guide ring groove 315 is provided on the inner wall of the regulating hole. A connecting hole 316 is provided on the regulating shaft 31 for connecting the guide ring groove 315 and the guide groove 312. The spray pipe 15 is connected to the guide ring groove 315.

[0046] The fixed connection between the adjusting shaft 31 and the adsorption packing 14 ensures that the rotation of the spray shaft 3 will not cause the adjusting shaft 31 to rotate synchronously. This design enables the spray pipe 15 to rotate while spraying, and simultaneously drive the suction plate 321 to rotate automatically around the adjusting shaft 31. Combined with the characteristics of the first reciprocating thread 311, this achieves the periodic up-and-down movement of the suction plate 321. In conjunction with the first one-way inlet valve 322 and the first one-way outlet valve 313, the up-and-down movement of the suction plate 321 can draw the treatment liquid in the treatment tower 1 into the suction tank 32, and then discharge it through the guide channel 312 and transport it to the spray pipe 15. This design achieves both the rotational spraying of the spray pipe 15 and the automatic suction and transport of the treatment liquid, reducing the need for power equipment and lowering costs.

[0047] Please see Figure 2 , Figure 3 and Figure 8 In this embodiment, the treatment tower 1 is provided with a plurality of fixed rods 161 fixedly connected to the circulation pipe 16, the spray shaft 3 is provided with a connecting ring groove, and a connecting ring box 162 is provided in the connecting ring groove for sliding and sealing connection. The bottom of the circulation pipe 16 is connected to the connecting ring box 162, and the water inlet holes 323 are all connected to the connecting ring box 162. The spray shaft 3 is provided with an adjusting ring plate 36 that can move up and down. The adjusting ring plate 36 is provided with a plurality of connecting rods 371 connected to the sludge scraping ring plate 37. The spray shaft 3 is provided with a second reciprocating thread 35 that matches and is connected to the adjusting ring plate 36.

[0048] The fixing rod 161 can fix the circulation pipe 16. The design of the connecting ring box 162 not only realizes the connection between the circulation pipe 16 and the water inlet 323, but also realizes the rotational connection between the circulation pipe 16 and the spray shaft 3. This ensures that the rotation of the spray shaft 3 will not drive the circulation pipe 16 to rotate. In conjunction with the second reciprocating thread 35, the characteristics of the reciprocating thread can be used to realize the synchronous up and down movement of the adjusting ring plate 36 and the sludge scraping ring plate 37.

[0049] Please see Figure 8 , Figure 9 and Figure 10 In this embodiment, the inner wall of the scraper ring 37 is provided with multiple recovery grooves 372. The scraper 374 is slidably and sealingly connected in the recovery grooves 372. The multiple recovery grooves 372 are connected by synchronous grooves 375. The connecting rod 371 is provided with a connecting groove that communicates with the recovery grooves 372. The adjusting ring 36 is provided with a drive groove 364. The drive groove 364 is provided with a slidably and sealingly connected drive plate 363. The bottom of the drive groove 364 is provided with a first groove that communicates with the connecting groove. The side wall of the drive groove 364 is provided with a retractable locking tongue 369 for supporting and limiting the drive plate 363. The drive groove 364 is provided with a first spring 365 for driving the drive plate 363 to return to its initial position. A first linkage rod is provided below the adjusting ring 36. 362, the upper end of the first linkage rod 362 moves through the drive groove 364 and is fixedly connected to the drive plate 363. The scraper 374 is provided with multiple cleaning bristles 373. The drive groove 364 is provided with an ejection groove 366 on its side wall. The locking tongue 369 is located in the ejection groove 366. The ejection groove 366 is provided with a second spring 368 for automatically ejecting the locking tongue 369. The ejection groove 366 is provided with a flexible linkage 367 connected to the locking tongue 369. The second linkage rod 361 is provided above the adjusting ring plate 36. The bottom of the second linkage rod 361 moves through the ejection groove 366 and is connected to the linkage 367. The first linkage rod 362 is located above the connecting ring box 162. The spray shaft 3 is provided with a pressing ring plate 360 ​​for pressing the second linkage rod 361.

[0050] When the adjusting ring plate 36 moves to the bottom, the first linkage rod 362 contacts and is pressed against the connecting ring box 162. This automatically drives the drive plate 363 to move until the drive plate 363 is above the locking tongue 369. The locking tongue 369 automatically pops out due to the second spring 368, automatically locking the drive plate 363. The movement of the drive plate 363, driven by hydraulic pressure, allows the scraper 374 to automatically and synchronously retract. Thus, when the scraper ring plate 37 moves upward, the scraper 374 will not scrape impurities from the filter hole surface, allowing sufficient time for more impurities to accumulate on the outside of the filter holes, enabling them to better clump together. When the adjusting ring plate 36 moves to the top, the second linkage rod 361 is pressed against the ring plate 360. The compression and contraction mechanism, via the linkage 367, causes the locking tongue 369 to retract automatically. This allows the drive plate 363, now unsupported by the locking tongue 369, to automatically return to its initial position under the action of the first spring 365. Through hydraulic linkage, the scraper 374 automatically extends. As the scraper ring 37 moves downwards, the scraper 374 removes impurities from the outside of the filter holes, ensuring filtration efficiency and preventing blockage. Simultaneously, the clumps of impurities accumulated on the outside of the filter holes, after being scraped away, are pushed downwards by the scraper 374. Combined with the gravity of the clumps, this allows them to settle downwards more effectively, improving the solid-liquid separation efficiency in the treated liquid. This also allows impurities to accumulate better at the bottom of the treatment tower 1, facilitating better separation of impurities in the treated liquid during the pressure filtration process in the filter press 33.

[0051] Please see Figure 3 , Figure 6 and Figure 7 In this embodiment, the bottom of the treatment tower 1 is in the shape of an inverted frustum. The bottom of the spray shaft 3 is provided with a sludge discharge trough 34, and the spray shaft 3 is also provided with a plurality of filter press troughs 33. The filter press trough 33 is provided with a filter press plate 332 that can move up and down. The filter press trough 33 is provided with a sludge inlet hole 330 that communicates with the treatment tower 1 on one side. The sludge inlet hole 330 is provided with a second one-way water inlet valve 333. The side wall of the sludge discharge trough 34 is provided with a baffle trough 343 that communicates with the bottom of the corresponding filter press trough 33. The baffle trough 343 is provided with a baffle plate 341 that can move up and down. The baffle plate 341 is provided with a filter press screen plate 334 that is rotatably connected. The filter press screen plate 334 and the filter press trough 33 are slidably and sealed together. The bottom of the treatment tower 1 is provided with a collection trough 173 that communicates with the sludge discharge trough 34. The collection trough 173 is provided with a collection box 17. The bottom of the filter press trough 33 is also provided with a drain hole 336. The drain hole 336 is provided with a second one-way drain valve. The processing tower 1 has a discharge hole 172 on one side, which is connected to the collection tank 173. The discharge hole 172 is equipped with a handle 171, which is connected to the collection box 17.

[0052] The design of the filter press trough 33, filter press plate 332, filter screen plate 334, and baffle plate 341, in conjunction with the second one-way inlet valve 333 and the second one-way outlet valve, allows the filter press plate 332 to move up and down, automatically drawing sludge from the bottom of the treatment tower 1 into the filter press trough 33. The downward movement of the filter press plate 332 then achieves automatic sludge pressing and separation. The up and down movement of the baffle plate 341 and the rotation of the filter screen plate 334, combined with the downward movement of the baffle plate 341 and the rotation of the filter screen plate 334, ensures that after filtration, the impurities automatically rotate and fall into the sludge discharge trough 34, where they are automatically collected by the collection box 17. This design cleverly integrates filtration and pressing into a single process.

[0053] Please see Figure 3 , Figure 6 and Figure 7 In this embodiment, the filter press trough 33 is provided with a first hydraulic rod 331 for driving the filter press plate 332 to move up and down, the baffle trough 343 is provided with a second hydraulic rod 342 for driving the baffle plate 341 to move up and down, the bottom of the filter press trough 33 is also provided with a third hydraulic rod 338 for driving the filter screen plate 334 to rotate, the bottom of the filter screen plate 334 is provided with a guide plate 335 fixedly connected, the guide plate 335 is provided with an inclined sliding groove 337, the end of the third hydraulic rod 338 is provided with a connecting shaft 339, and the connecting shaft 339 is slidably connected to the sliding groove 337.

[0054] The inclined chute 337 design allows the third hydraulic rod 338 to extend, and through the inclination of the chute 337, the filter screen plate can rotate and tilt better, so that the sludge after pressing can fall into the sludge discharge trough 34 better, realizing automatic separation after pressing.

[0055] In this embodiment, the processing tower 1 is equipped with a drive motor 13, and the output end of the drive motor 13 is connected to the spray shaft 3 by gear meshing.

[0056] When this application is used:

[0057] The intake fan 2 is started to send industrial waste gas into the treatment tower 1 through the intake pipe 11. At the same time, the drive motor 13 is controlled to drive the spray shaft 3 and the spray pipe 15 to rotate synchronously. Since the adjustment shaft 31 is fixedly connected to the adsorption packing 14, the spray shaft 3 drives the suction plate 321 to rotate automatically around the adjustment shaft 31. With the characteristics of the first reciprocating thread 311, and in conjunction with the first one-way water inlet valve 322 and the first one-way drain valve 313, the treatment liquid after filtration through the filter hole can be automatically drawn into the suction tank 32, and then automatically pressed through the guide channel 312 to the spray pipe 15 and sprayed out through the spray pipe 15. This realizes that the treatment liquid at the bottom of the treatment tower 1 is sprayed into the treatment tower 1 by rotating spraying. This allows the impurities and harmful substances in the industrial waste gas entering the treatment tower 1 to be contacted, adsorbed and separated by the treatment liquid.

[0058] After adsorbing impurities, the treatment liquid automatically falls into the treatment tower 1 due to gravity. With the continuous suction of the filter holes, impurities can be continuously accumulated on the outside of the filter holes. Due to the fixing rod 161 fixing the circulation pipe 16 and the cooperation of the connecting ring box 162, plus the second reciprocating thread 35, when the spray shaft 3 continues to rotate, the adjusting ring plate 36 can automatically move up and down periodically under the action of the second reciprocating thread 35, so that the sludge scraping ring plate 37 moves up and down synchronously.

[0059] When the adjusting ring plate 36 moves to the bottom, the first linkage rod 362 contacts and is pressed against the connecting ring box 162. This automatically drives the drive plate 363 to move until it is above the locking tongue 369. The pressing is then complete, and the locking tongue 369 automatically pops out due to the second spring 368, automatically locking the drive plate 363. The movement of the drive plate 363, driven by hydraulic pressure, allows the scraper 374 to automatically and synchronously retract. Thus, when the scraper ring plate 37 moves upward, the scraper 374 will not scrape impurities from the filter hole surface, ensuring proper filtration. Sufficient time is allowed for the outer side of the hole to accumulate more impurities, allowing them to better clump together. When the adjusting ring plate 36 moves to its uppermost position, the second linkage rod 361 is squeezed and contracted by the pressing ring plate 360. Through the linkage 367, the locking tongue 369 automatically retracts. Thus, the drive plate 363, which loses the support of the locking tongue 369, can automatically return to its initial position under the action of the first spring 365. Through hydraulic linkage, the scraper 374 can automatically extend. When the mud scraping ring plate 37 moves downward, the scraper 374 can scrape off the impurities on the outside of the filter hole, ensuring the filtration efficiency of the filter hole and preventing clogging.

[0060] When a certain amount of impurities accumulate at the bottom of the treatment tower 1, the first hydraulic rod 331 is activated to move up and down periodically. In conjunction with the second one-way water inlet valve 333 and the filter screen plate 334, the treatment liquid containing impurities can be automatically drawn into the filter tank 33 and automatically filtered by the filter plate 332, causing the impurities in the filter tank 33 to increase continuously. When the impurities accumulate to a certain amount, the first hydraulic rod 331 is controlled to continue to press downwards, and the sludge on the filter screen plate 334 is pressed to the set moisture content, and the filtration is completed.

[0061] After the filter press is completed, the filter press plate 332 is positioned at the mud inlet hole 330, so that the filter press plate 332 seals the mud inlet hole 330. Then, the second hydraulic rod 342 and the third hydraulic rod 338 are controlled to retract synchronously, so that the filter screen plate 334 and the impurities move downward synchronously. When the second hydraulic rod 342 retracts to the set height, the third hydraulic rod 338 is activated to extend, which can drive the filter screen plate 334 to rotate automatically. With the tilt of the slide groove 337, the filter screen plate 334 can rotate better, allowing the impurities on the surface of the filter screen plate 334 to fall off and separate better, realizing the automatic separation of impurities after the filter press is completed.

[0062] After separation, the impurities automatically fall into the collection box 17, and then the impurities in the collection box 17 can be removed by using the handle 171.

[0063] An industrial waste gas treatment method, using the aforementioned industrial waste gas treatment device, includes the following steps:

[0064] S1 starts the intake fan 2 to send industrial waste gas into the treatment tower 1 through the intake pipe 11. At the same time, it controls the drive mechanism to spray the treatment liquid at the bottom of the treatment tower 1 into the treatment tower 1 by spraying, so that the impurities and harmful substances in the industrial waste gas entering the treatment tower 1 are contacted, adsorbed and separated by the treatment liquid.

[0065] S2 then controls the spray shaft 3 to rotate, so that the spray pipe 15 rotates and sprays, thereby making the treatment liquid more evenly distributed in the treatment tower 1 and improving the treatment effect.

[0066] The gas adsorbed by the S3 spray is then adsorbed again by the adsorption packing 14 and discharged through the exhaust pipe 12.
