Description

Technical Field

[0001] The present invention belongs to the technical field of industrial waste gas treatment, and in particular relates to an industrial waste gas treatment device and a method thereof. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes in the factory area of ​​an enterprise. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, lead and mercury sulfate, beryllium, smoke and production dust, which are discharged into the atmosphere and pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them directly cause harm, while others have an accumulation effect, which will more seriously endanger human health. Therefore, for some industrial waste gases, it is necessary to filter the dust particles in them, absorb the harmful components through chemical absorbents, and achieve purification of industrial waste gases.

[0003] The inventors have found that when treating existing industrial waste gas, especially when the dust particle content in the waste gas is high, it is easy to cause a high impurity content in the treatment liquid (i.e., absorbent). As a result, when the treatment liquid is circulated and sprayed, the impurities cannot be quickly and effectively separated from the treatment liquid, which can easily cause blockage. As a result, when the waste gas is treated, the treatment liquid cannot be fully and effectively sprayed and adsorbed, affecting the overall waste gas treatment efficiency.

[0004] Therefore, the existing structure and defects are studied and improved, and an industrial waste gas treatment device and method are provided to achieve a more practical purpose. Summary of the invention

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

[0017] S1 starts the air intake fan to send the industrial waste gas into the treatment tower through the air intake pipe, and at the same time controls the driving 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, and by rotating, the spray pipe is rotated to spray, so that the treatment liquid is more evenly distributed in the treatment tower, improving the treatment effect;

[0019] The gas after S3 spray adsorption is adsorbed again by the adsorption filler and then 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 the spray shaft can realize the rotary spraying of the spray pipe through the rotation of the spray shaft, so that the treatment liquid is sprayed and distributed more evenly in the treatment tower, thereby effectively increasing the contact probability between the treatment liquid and the industrial waste gas and improving the overall treatment efficiency; the addition of adsorption filler can further improve the waste gas treatment efficiency through the re-adsorption of the adsorption filler.

[0022] The design of the circulation pipe and the conveying mechanism realizes the recycling of the treatment liquid in the treatment tower, which effectively reduces the cost. The vertical design of the circulation pipe and the combination of filter holes can effectively prevent impurities from accumulating on the outside of the filter holes and effectively prevent the filter holes from being blocked. In addition, the scraper ring plate and the scraper can move up and down with the scraper ring plate to promptly scrape down the impurities on the surface of the filter holes, so that the impurities can be better accumulated 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 filler ensures that the rotation of the spray shaft will not drive the synchronous rotation of the adjusting shaft. This design enables the spray pipe to drive the suction plate to automatically rotate around the adjusting shaft while rotating and spraying. Combined with the characteristics of the first reciprocating thread, the periodic up and down movement of the suction plate is realized. In conjunction with the first one-way water inlet valve and the first one-way drain valve, the up and down movement of the suction plate can suck the treatment liquid in the treatment tower into the suction groove, and then discharge it through the guide groove and transport it to the spray pipe. This design not only realizes the rotation spraying of the spray pipe, but also realizes the automatic suction and transportation of the treatment liquid, reduces the addition of power equipment, and reduces costs.

The spray pipes 15 are staggered.

[0043] The design of the spray pipe 15 and the spray shaft 3 can realize the rotary spraying of the spray pipe 15 through the rotation of the spray shaft 3, so that the treatment liquid is sprayed and distributed more evenly in the treatment tower 1, thereby effectively improving the contact probability between the treatment liquid and the industrial waste gas and improving the overall treatment efficiency; the addition of the adsorption filler 14 can further improve the treatment efficiency of the waste gas through the re-adsorption of the adsorption filler 14;

[0044] The design of the circulation pipe 16 and the conveying mechanism realizes the recycling of the treatment liquid in the treatment tower 1, which effectively reduces the cost. The vertical design of the circulation pipe 16 and the combination of the filter holes can effectively prevent impurities from accumulating on the outside of the filter holes and effectively prevent the filter holes from being blocked. In addition, the scraper ring plate 37 and the scraper 374 can move up and down through the scraper ring plate 37, and the scraper 374 can timely scrape the impurities on the surface of the filter holes downward, so that the impurities can be better accumulated at the bottom of the treatment tower 1, while ensuring the filtering efficiency of the filter holes and preventing blockage.

[0045] See also 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. A rotating and sealed adjustment shaft 31 is provided in the adjustment hole.

The adjustment shaft 31 is also provided with a first reciprocating thread 311 matched with the suction plate 321. The bottom of the suction groove 32 A plurality of water inlet holes 323 connected with the circulation pipe 16 are provided, a first one-way water inlet valve 322 is provided in the water inlet hole 323, a guide groove 312 is provided in the adjusting shaft 31, and a plurality of water outlet grooves 314 connected with the guide groove 312 are provided at the bottom of the adjusting 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 adjusting hole, a connecting hole 316 for connecting the guide ring groove 315 with the guide groove 312 is provided on the adjusting shaft 31, and the spray pipe 15 is connected with the guide ring groove 315.

[0046] The fixed connection between the adjusting shaft 31 and the adsorption filler 14 ensures that the rotation of the spray shaft 3 will not drive the synchronous rotation of the adjusting shaft 31. This design enables the spray pipe 15 to drive the suction plate 321 to automatically rotate around the adjusting shaft 31 while rotating and spraying. Combined with the characteristics of the first reciprocating thread 311, the periodic up and down movement of the suction plate 321 is achieved. In conjunction with the first one-way water inlet valve 322 and the first one-way drain valve 313, the up and down movement of the suction plate 321 can suck the treatment liquid in the treatment tower 1 into the suction groove 32, and then discharge it through the guide groove 312 and transport it to the spray pipe 15. This design not only realizes the rotation spraying of the spray pipe 15, but also realizes the automatic suction and transportation of the treatment liquid, reduces the addition of power equipment, and reduces costs.

[0047] See also Figure 2 , Figure 3 and Figure 8 In this embodiment, a plurality of fixing rods 161 fixedly connected to the circulation pipe 16 are provided in the treatment tower 1, a connecting ring groove is provided on the spray shaft 3, a connecting ring box 162 which is slidably and sealed is provided in the connecting ring groove, the bottom of the circulation pipe 16 is communicated with the connecting ring box 162, the water inlet holes 323 are all communicated with the connecting ring box 162, an adjusting ring plate 36 which can move up and down is provided on the spray shaft 3, a plurality of connecting rods 371 connected to the scraper ring plate 37 are provided on the adjusting ring plate 36, and a second reciprocating thread 35 which is matched and connected to the adjusting ring plate 36 is provided on the spray shaft 3.

[0048] The fixing rod 161 can fix the circulation pipe 16, and the design of the connecting ring box 162 not only realizes the connection between the circulation pipe 16 and the water inlet hole 323, but also realizes the rotation connection between the circulation pipe 16 and the spray shaft 3, so that the rotation of the spray shaft 3 will not drive the circulation pipe 16 to rotate. Combined with the second reciprocating thread 35, the characteristics of the reciprocating thread can be utilized to realize the synchronous up and down movement of the adjustment ring plate 36 and the scraper ring plate 37.

[0049] See also Figure 8 , Fig. 9 and Fig.10 In this embodiment, a plurality of recovery grooves 372 are provided on the inner side wall of the scraper ring plate 37, and a scraper plate 374 is slidably and sealedly connected in the recovery groove 372. A plurality of recovery grooves 372 are provided with a synchronous groove 375 connected thereto, and a connecting groove connected to the recovery groove 372 is provided in the connecting rod 371. A driving groove 364 is provided in the adjusting ring plate 36, and a driving plate 363 slidably and sealedly connected thereto is provided in the driving groove 364, and a first groove connected to the connecting groove is provided at the bottom of the driving groove 364, and a retractable locking tongue 369 used for supporting and limiting the driving plate 363 is provided on the side wall of the driving groove 364, and a first spring 365 used for driving the driving plate 363 to restore the initial position is provided in the driving groove 364, and a first linkage rod is provided below the adjusting ring plate 36 362, the upper end of the first linkage rod 362 movably passes through the driving groove 364 and is fixedly connected to the driving plate 363, a plurality of cleaning brushes 373 are provided on the scraper 374, an ejection groove 366 is provided on the side wall of the driving groove 364, a locking tongue 369 is arranged in the ejection groove 366, a second spring 368 for driving the locking tongue 369 to automatically pop out is provided in the ejection groove 366, and a bendable linkage member 367 connected to the locking tongue 369 is provided in the ejection groove 366, a second linkage rod 361 is provided above the adjusting ring plate 36, the bottom of the second linkage rod 361 movably passes through the ejection groove 366 and is connected to the linkage member 367, the first linkage rod 362 is located above the connecting ring box 162, and a pressing ring plate 360 ​​for pressing the second linkage rod 361 is provided on the spray shaft 3.

[0050] When the adjusting ring plate 36 moves to the bottom, the first linkage rod 362 contacts the connecting ring box 162 and is pressed, thereby automatically driving the driving plate 363 to move through the first linkage rod 362 until the driving plate 363 is located above the locking tongue 369. The pressing is completed, and the locking tongue 369 can automatically pop out due to the second spring 368, so that the driving plate 363 is automatically locked. The movement of the driving plate 363 can be driven by hydraulic pressure to realize the automatic synchronous contraction of the scraper 374. In this way, when the scraper ring plate 37 moves upward, the scraper 374 will not scrape impurities on the surface of the filter hole, so that the outside of the filter hole can have enough time to accumulate more impurities, which can make the impurities better bonded into a ball. When the adjusting ring plate 36 moves to the uppermost end, the second linkage rod 361 is pressed against the ring plate 360 The locking tongue 369 is squeezed and contracted through the linkage 367 to automatically contract, so that the driving plate 363 that loses the support of the locking tongue 369 can automatically restore the initial position under the action of the first spring 365, and can drive the scraper 374 to automatically extend through the hydraulic linkage, so that when the scraper ring plate 37 moves downward, the scraper 374 can scrape off the impurities on the outside of the filter hole to ensure the filtering efficiency of the filter hole and prevent blockage. At the same time, the impurities accumulated on the outside of the filter hole can be pushed downward by the scraper 374 after being scraped off. With the gravity of the impurities themselves, the impurities can be better precipitated downward, thereby improving the solid-liquid separation efficiency in the treated liquid and allowing the impurities to be better accumulated at the bottom of the treatment tower 1, so that the filter press tank 33 can better separate the impurities in the treated liquid during the filter press separation.

[0052] The design of the filter press tank 33, the filter press plate 332, the filter press screen plate 334 and the baffle plate 341, in conjunction with the second one-way water inlet valve 333 and the second one-way drain valve, can automatically suck the sludge at the bottom of the treatment tower 1 into the filter press tank 33 through the up and down movement of the filter press plate 332, and realize the automatic filter pressing and separation of the sludge through the downward movement of the filter press plate 332, and the up and down movement of the baffle plate 341 and the rotation of the filter press screen plate 334 can realize that after the filter pressing is completed, the impurities after the filter pressing can automatically rotate and fall into the mud discharge tank 34 through the downward movement of the baffle plate 341 and the rotation of the filter press screen plate 334, and are automatically collected by the collection box 17. Such a design can cleverly integrate filtration and filter pressing together.

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

[0055] In this embodiment, a driving motor 13 is provided in the processing tower 1, and an output end of the driving motor 13 is meshedly connected to the spray shaft 3 via a gear.

Since the adjusting shaft 31 is fixedly connected to the adsorption filler 14, the spray shaft 3 drives the suction plate 321 to automatically rotate around the adjusting shaft 31. In addition, the characteristics of the first reciprocating thread 311, the first one-way water inlet valve 322, and the first one-way drain valve 313 are combined, so that the treatment liquid filtered by the filter hole can be automatically sucked into the suction groove 32, and then automatically pressed to the spray pipe 15 through the guide groove 312, and sprayed out through the spray pipe 15, so that the treatment liquid at the bottom of the treatment tower 1 is sprayed into the treatment tower 1 by rotating spraying, so that the impurities and harmful substances in the industrial waste gas entering the treatment tower 1 can be contacted, adsorbed and separated by the treatment liquid;

[0058] The treated liquid after adsorbing impurities automatically falls into the treatment tower 1 due to gravity, and with the continuous suction of the filter holes, the impurities can be continuously accumulated outside the filter holes; due to the fixing of the circulation pipe 16 by the fixing rod 161, 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 and periodically move up and down under the action of the second reciprocating thread 35, so that the scraper 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 the connecting ring box 162 and is pressed, thereby automatically driving the driving plate 363 to move through the first linkage rod 362 until the driving plate 363 is above the locking tongue 369. The pressing is completed, and the locking tongue 369 can automatically pop out due to the second spring 368, so that the driving plate 363 is automatically locked. The movement of the driving plate 363 can be driven by hydraulic pressure to realize the automatic synchronous contraction of the scraper 374. In this way, when the scraper ring plate 37 moves upward, the scraper 374 will not scrape impurities on the surface of the filter hole, which can make the filter The outer side of the hole can have enough time to accumulate more impurities, which can make the impurities better bonded into a ball. When the adjusting ring plate 36 moves to the uppermost end, the second linkage rod 361 is pressed and squeezed by the ring plate 360, and the locking tongue 369 is automatically retracted through the linkage member 367. In this way, the driving plate 363 that loses the support of the locking tongue 369 can automatically restore the initial position under the action of the first spring 365, and can drive the scraper 374 to automatically extend through the hydraulic linkage. In this way, when the scraper ring plate 37 moves downward, the scraper 374 can scrape off the impurities on the outer side of the filter hole, thereby ensuring the filtering efficiency of the filter hole and preventing blockage.

[0060] When a certain amount of impurities accumulate at the bottom of the treatment tower 1, the first hydraulic rod 331 is started to move up and down periodically, and the second one-way water inlet valve 333, the second one-way water inlet valve 333 and the filter press screen plate 334 are cooperated to automatically suck the treatment liquid containing impurities into the filter press tank 33, and the filter press plate 332 is automatically filtered, so that the impurities in the filter press tank 33 continue to increase. When the impurities accumulate to a certain amount, the first hydraulic rod 331 is controlled to continue to press downward, and the sludge on the filter press screen plate 334 is filtered to the set water content, and the filtration is completed;

[0061] When the filtration is completed, the filter press plate 332 is controlled to be located at the mud inlet hole 330, so that the filter press plate 332 seals the mud inlet hole 330, and then the second hydraulic rod 342 and the third hydraulic rod 338 are controlled to shrink synchronously, so that the filter press mesh plate 334 and the impurities move downward synchronously. When the second hydraulic rod 342 shrinks to the set height, the third hydraulic rod 338 is started to extend, which can drive the filter press mesh plate 334 to rotate automatically, and cooperate with the inclination of the chute 337, so that the filter press mesh plate 334 can rotate better, so that the impurities on the surface of the filter press mesh plate 334 can fall and separate better, realizing the automatic separation of impurities after the filtration is completed.

[0062] After being separated, the impurities automatically fall into the collection box 17 , and then the impurities in the collection box 17 can be taken out through the handle 171 .

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

[0064] S1 starts the air intake fan 2 to send the industrial waste gas into the treatment tower 1 through the air intake pipe 11, and at the same time controls the driving 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, and by rotating, the spray pipe 15 is caused to spray in a rotating manner, so that the treatment liquid is more evenly distributed in the treatment tower 1, thereby improving the treatment effect;

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