[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The circulating industrial waste gas treatment device disclosed in this utility model is mainly used in scenarios where existing dust suppression devices suffer from severe particulate matter residue due to short single-process flow and insufficient waste gas residence time, which adheres to the inner wall of the device and is difficult to clean, thus reducing the waste gas filtration efficiency.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A circulating industrial waste gas treatment device includes a support frame 8; a dust settling chamber 7, which is located above the support frame 8, with one end of the dust settling chamber 7 fixedly connected to an inlet waste gas pipe 12 and the other end fixedly connected to an outlet gas pipe 9; a filter chamber 1, which is located above the dust settling chamber 7, with one side of the filter chamber 1 fixedly connected to the outlet end of the outlet gas pipe 9; and a dust settling assembly 13, which is located inside the dust settling chamber 7. The dust settling assembly 13 includes multiple annular connecting seats 1306, which are fixedly connected at equal intervals to the outside of the dust settling chamber 7. The inner walls of the multiple annular connecting seats 1306 are fixedly connected at equal intervals to extension springs 1309. One end of each extension spring 1309 is fixedly connected to a fixing plate 1310. One side of each fixing plate 1310 is fixedly connected to the same partition 1311. The partitions 1311 are arranged at equal intervals inside the dust settling chamber 7 according to the position of the outlet gas holes.

[0024] Reference Figure 1 , Figure 4 and Figure 5 In a preferred embodiment, each of the multiple partitions 1311 has a circular toothed hole on one side, and the circular toothed hole is located at the center of one side of the partition 1311. A power motor 1301 is fixedly connected to one side of the dust settling chamber 7, and the power motor 1301 is located below the exhaust gas inlet pipe 12. The drive end of the power motor 1301 is fixedly connected to one end of the connecting shaft 1302 via a coupling. A water conveying rotating rod 1307 is fixedly connected to one side of the connecting shaft 1302, and the water conveying rotating rod 1307 is movably connected to the rotating holes opened on opposite sides of the dust settling chamber 7. A toggle sleeve 1308 is fixedly connected to the outside of 1307. The toggle sleeve 1308 is located inside the circular toothed hole of the partition 1311. The toggle plate on the toggle sleeve 1308 abuts against the circular toothed hole. Multiple connecting rods 1304 are fixedly connected to the outside of the water conveying rotating rod 1307. The multiple connecting rods 1304 are arranged inside the partition 1311 and the dust settling chamber 7. Multiple atomizing nozzles 1305 are fixedly connected to both sides of the connecting rod 1304. Scraper blades 1303 are fixedly connected to both ends of the connecting rod 1304. One side of the scraper blade 1303 contacts the inner wall of the dust settling chamber 7.

[0025] When reducing dust in exhaust gas, the power motor 1301 is turned on, driving the water conveying rotating rod 1307, which is fixedly connected to the connecting shaft 1302, to rotate continuously. The atomizing nozzle 1305, which is fixedly connected to the connecting rod 1304, forms a water curtain under continuous rotation, which performs dust reduction treatment on the exhaust gas input from the exhaust gas inlet pipe 12. The particulate matter in the exhaust gas is removed by being enveloped by the water mist. Since the atomizing nozzle 1305 on the connecting rod 1304 is fixedly connected to both sides, two water curtains are formed, increasing the number of times the water curtain contacts the exhaust gas, so that the particles in the exhaust gas are better removed. Meanwhile, the scraper blades 1303, which are fixedly connected to both ends of the connecting rod 1304, continuously scrape the dust in the dust reduction chamber 7 during rotation. The particles adhering to the wall are scraped off to prevent them from accumulating and clogging the pipes. If left untreated for a long time, they are difficult to clean. As the water conveying rotating rod 1307 rotates, the actuating sleeve 1308 fixedly connected to the water conveying rotating rod 1307 also rotates continuously. The actuating plate on the actuating sleeve 1308 continuously applies force to the circular toothed hole in the partition 1311. Since the partition 1311 has a telescopic spring 1309 and a fixed plate 1310 fixedly connected to the inner wall of the annular connecting seat 1306, the partition 1311 vibrates inside the dust settling chamber 7, causing the particles adhering to the partition 1311 to fall off, thus preventing the exhaust gas particles from clogging the air conveying holes on the partition 1311.

[0026] Reference Figure 1 and Figure 6 In a preferred embodiment, a circulating sewage discharge assembly 14 is fixedly connected to one side of the dust settling chamber 7, and the circulating sewage discharge assembly 14 includes a water filter tank 1402. Sewage discharge holes are equally spaced on one side of the bottom of the dust settling chamber 7. The same sewage discharge pipe 1406 is fixedly connected inside the multiple sewage discharge holes. A second water pump 1405 is fixedly connected to the outside of the sewage outlet end of the sewage discharge pipe 1406. A water filter tank 1402 is fixedly connected to one side of the sewage discharge pipe 1406. A pull-out filter tank 1401 is slidably connected inside the water filter tank 1402. A water filter hole is opened on one side of the pull-out filter tank 1401. A water supply hole is opened on one side of the water filter tank 1402. A water supply pipe 1404 is fixedly connected inside the water supply hole. A first water pump 1403 is fixedly connected to the outside of the water inlet end of the water supply pipe 1404.

[0027] During the dust suppression process, the wastewater discharged from the dust suppression chamber 7 is transported to the water filter box 1402 through the drain pipe 1406 by turning on the second water pump 1405. The wastewater is filtered by the water filter holes on one side of the pull-out filter box 1401, and impurities are left in the pull-out filter box 1401. The filtered water is then transported back to the water conveying rotating rod 1307 through the water conveying pipe 1404 by turning on the first water pump 1403. This process recycles water resources and avoids waste. At the same time, the filtration of the pull-out filter box 1401 makes sewage discharge more convenient.

[0028] Reference Figure 1 and Figure 2 In a preferred embodiment, a plurality of pull-out filter elements 10 are slidably connected inside the filter chamber 1, and an air inlet is provided on one side of the filter chamber 1. The air inlet of the circulation pipe 11 is fixedly connected inside the air inlet, and the air outlet of the circulation pipe 11 is fixedly connected to the outside of the air outlet of the exhaust pipe 12. A monitor 2 and a vacuum pump 3 are fixedly connected to the outside of the end of the circulation pipe 11 near the filter chamber 1. The monitor 2 is located between the vacuum pump 3 and the filter chamber 1. A solenoid valve 6 and a clean air outlet pipe 4 are fixedly connected to the outside of the end of the circulation pipe 11 near the exhaust pipe 12. The solenoid valve 6 is located between the exhaust pipe 12 and the clean air outlet pipe 4. A solenoid valve 5 is fixedly connected to the outside of the clean air outlet pipe 4.

[0029] After dust suppression, the exhaust gas is transported to the filter chamber 1 through the air supply pipe 9. The harmful substances in the exhaust gas are filtered out by the pull-out filter element 10 in the filter chamber 1. The filtered exhaust gas is then transported to the circulation pipe 11. At this time, the monitor 2 on the circulation pipe 11 detects the components in the filtered exhaust gas. If the detection meets the emission standards, the solenoid valve 5 is opened to allow the filtered exhaust gas to be discharged through the clean air outlet pipe 4. If the detection does not meet the emission standards, the solenoid valve 6 is opened to allow the filtered exhaust gas to be transported back into the exhaust gas pipe 12 for filtration again. This process of multiple circulation treatments ensures that the exhaust gas meets the emission standards.

[0030] Working principle: When reducing dust from exhaust gas, first close solenoid valve 5 and solenoid valve 6, then turn on vacuum pump 3 to put the entire exhaust gas treatment device into a vacuum negative pressure state. Then, exhaust gas is introduced and enters the dust collection chamber 7 through exhaust gas inlet pipe 12. Subsequently, the power motor 1301 is turned on to drive the water conveying rotating rod 1307, which is fixedly connected to the connecting shaft 1302, to rotate continuously. The atomizing nozzle 1305, which is fixedly connected to the connecting rod 1304, forms a water curtain under continuous rotation, which performs dust reduction treatment on the exhaust gas input from the exhaust gas inlet pipe 12. The particulate matter in the exhaust gas is removed by being enveloped by the water mist. The scraper blades 1303, which are fixedly connected to both ends of the connecting rod 1304, continuously scrape off the particulate matter attached to the inner wall of the dust collection chamber 7 during the rotation. As the water conveying rotating rod 1307 rotates, the particulate matter fixedly connected to the water conveying rotating rod 1307... The actuating sleeve 1308 on the upper part also rotates continuously, and the actuating plate on the actuating sleeve 1308 continuously applies force to the circular toothed hole in the partition 1311 it abuts, causing the partition 1311 to vibrate inside the dust settling chamber 7, causing the particles attached to the partition 1311 to fall off. Then, the exhaust gas after dust settling is transported to the filter chamber 1 through the air supply pipe 9. Through the action of the pull-out filter element 10 in the filter chamber 1, harmful substances in the exhaust gas are filtered out. Then, the filtered exhaust gas is transported to the circulation pipe 11. At this time, the monitor 2 on the circulation pipe 11 detects the components in the filtered exhaust gas. If the detection meets the emission standards, the solenoid valve 5 is opened to allow the filtered exhaust gas to be discharged through the clean air outlet pipe 4. If the detection does not meet the emission standards, the solenoid valve 6 is opened to allow the filtered exhaust gas to be transported back into the exhaust gas pipe 12 for further filtration.

[0031] During the dust suppression process, the wastewater discharged from the dust suppression chamber 7 is transported to the water filter box 1402 through the drain pipe 1406 by turning on the second water pump 1405. The wastewater is filtered by the water filter hole on one side of the pull-out filter box 1401, and the impurities are left in the pull-out filter box 1401. The filtered water is then transported back to the water conveying rotating rod 1307 through the water conveying pipe 1404 by turning on the first water pump 1403.

[0032] After the exhaust gas is treated, the workers will collect the impurities and dirt from the pull-out filter box 1401.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
