However, due to the large size and high cost of the waste gas purification device and the fast energy consumption during use, some production links with less pollution and less waste gas often do not use waste gas purification devices. However, in the long-term production process, with the accumulation of time, the waste gas will also cause damage to the atmosphere and even the health of the workers. In addition, the structure of the existing waste gas purification device is relatively complex. If problems occur during the purification process, it is difficult to repair.

DETAILED DESCRIPTION The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-10 , an embodiment of the present invention provides: a waste gas purification device for pollution control, comprising a condensation impurity removal box 1, a coarse filtration impurity removal box 2 is fixedly installed on the rear side of the condensation impurity removal box 1, a hydrolysis impurity removal box 3 is fixedly installed on the rear side of the coarse filtration impurity removal box 2, an exhaust gas inlet connecting pipe 4 is fixedly installed at the upper right corner of the front side of the condensation impurity removal box 1, a thread is arranged in the exhaust gas inlet connecting pipe 4, a condensation connecting pipe 5 is fixedly installed in the condensation impurity removal box 1, the upper side of the condensation connecting pipe 5 is connected to the exhaust gas inlet connecting pipe 4, the other end of the condensation connecting pipe 5 is connected to the exhaust gas discharge oblique pipe 6, the exhaust gas discharge oblique pipe 6 is fixedly installed in the coarse filtration impurity removal box 2, and a rotating device in the coarse filtration impurity removal box 2 is provided. A coarse filter movable filter disc 7 is installed, the other end of the exhaust gas discharge inclined pipe 6 is open and fits with the coarse filter movable filter disc 7, an exhaust gas discharge L-shaped pipe 8 is fixedly installed in the hydrolysis impurity removal box 3, and the exhaust gas discharge L-shaped pipe 8 is connected with the coarse filter impurity removal box 2, a fine filter adsorption layer installation pipe 9 is fixedly installed on one side of the hydrolysis impurity removal box 3, and the fine filter adsorption layer installation pipe 9 is connected with the hydrolysis impurity removal box 3, a first threaded ring 10 is fixedly installed on the upper side of the condensation impurity removal box 1, and a water inlet threaded plug 11 is threadedly installed in the first threaded ring 10, a second threaded ring 12 is fixedly installed on the lower end of one side of the condensation impurity removal box 1, and a water outlet threaded plug 13 is threadedly installed in the second threaded ring 12. The device is small in size, but has many exhaust gas purification processes, which are divided into four parts: condensation, coarse filtration, hydrolysis and fine filtration. It can effectively purify the exhaust gas, and the impurities filtered out in the equipment can also be discharged, which increases the functionality and reusability of the equipment when in use. Moreover, due to the small size and regular shape of the equipment, it is easy to carry and is suitable for some emergency exhaust gas treatment and some small-scale exhaust gas treatment situations, which increases the convenience of using the equipment. The hydrolyzate set inside the equipment can not only absorb impurities in the exhaust gas by fusing with the exhaust gas, but also condense the exhaust gas by its own temperature, effectively utilizing the characteristics of the hydrolyzate and optimizing the structure of the equipment.

[0020] Furthermore, the condensation connecting pipe 5 is U-shaped, and a connecting and mounting block 14 is fixedly installed at the center position of the lower end of the condensation connecting pipe 5, and the connecting and mounting block 14 is connected to the lower end of the condensation connecting pipe 5. A first impurity storage box 15 is movably inserted in the connecting and mounting block 14, and the first impurity storage box 15 is opposite to the lower side of the condensation connecting pipe 5. This structure allows the condensation and impurity removal box 1 to be filled with hydrolyzed liquid, and the hydrolyzed liquid can condense the exhaust gas in the condensation connecting pipe 5 by its own temperature. The impurities in the condensation connecting pipe 5 after condensation can be accumulated in the first impurity storage box 15 under the action of gravity, so that the impurities will not block the condensation connecting pipe 5, so that the flow of the exhaust gas in the condensation connecting pipe 5 is smoother, and the stability of the equipment during use is increased. Moreover, the impurities can be concentrated in the first impurity storage box 15, which increases the convenience of the equipment when discharging impurities. The shape design of the condensation connecting pipe 5 itself can increase the contact area between the hydrolyzed liquid and the exhaust gas, so as to improve the cooling efficiency of the exhaust gas in the condensation connecting pipe 5.

[0021] Furthermore, four sets of first screw sleeves 16 are fixedly installed at the edge of the exhaust gas entering the connecting pipe 4, four sets of first screw rods 17 are movably inserted in the first impurity storage box 15, and the first screw rods 17 are installed in the first screw sleeves 16 by threads. A storage box holding groove 18 is opened on the front side of the first impurity storage box 15, and a storage box holding block 19 is fixedly installed in the storage box holding groove 18. The storage box holding block 19 is wide at both sides and narrow in the middle. Figure 1 As shown, the first impurity storage box 15 is flush with the front side of the condensation and impurity removal box 1 after installation, which can increase the aesthetics of the equipment and the convenience of storage, but this makes it difficult to take out the first impurity storage box 15. The provided storage box holding block 19 allows the first impurity storage box 15 to be easily pulled out, increasing the convenience of using the equipment.

[0022] Furthermore, a gear ring 20 is fixedly installed on the outer side of the coarse filter movable filter disc 7, a rotary motor 21 is fixedly installed in the hydrolysis impurity removal box 3, a driving gear 22 is fixedly installed on the output shaft of the rotary motor 21, the driving gear 22 is rotatably installed in the coarse filter impurity removal box 2, and the gear ring 20 is meshed with the rotary motor 21. This structure allows the coarse filter movable filter disc 7 to rotate slowly under the drive of the rotary motor 21, so that the exhaust gas can contact different positions of the coarse filter movable filter disc 7, thereby realizing efficient use of the coarse filter movable filter disc 7, and in addition, this structure can prevent the position where the coarse filter movable filter disc 7 contacts the exhaust gas from being blocked by impurities for a long time, so that the exhaust gas will not be unable to be filtered due to blockage during the coarse filtration process.

[0023] Furthermore, a scraping plate mounting block 24 is fixedly installed in the coarse filtering and impurity removing box 2, and an impurity scraping plate 25 is movably arranged in the scraping plate mounting block 24. The impurity scraping plate 25 has a sharp end, and a spring 26 is fixedly installed in the scraping plate mounting block 24. The spring 26 abuts against the impurity scraping plate 25. The scraping plate mounting block 24 is not perpendicular to the coarse filtering and impurity removing box 2, and a second impurity storage box 27 is movably arranged on the lower side of the scraping plate mounting block 24. This structure allows the coarse filtering movable filter disc 7 to be cleaned by the scraping of the impurity scraping plate 25 during the rotation process, and the impurities scraped off by the impurity scraping plate 25 can be concentrated in the second impurity storage box 27, so that the impurities can be collected, thereby further reducing the probability of clogging of the coarse filtering movable filter disc 7 and increasing the stability of the equipment during use.

[0024] Furthermore, a mounting groove 28 is provided at the lower left end of the coarse filtering and impurity removing box 2, a fixing plate 29 is fixedly installed at the end of the second impurity storage box 27, two sets of second screw sleeves 30 are fixedly installed in the mounting groove 28, a second screw rod 31 is movably inserted in the fixing plate 29, the second screw rod 31 is installed in the second screw sleeve 30 by threading, and a pull block 32 is fixedly installed at the end of the fixing plate 29. This structure allows the second impurity storage box 27 to be drawn out, so that the impurities in the second impurity storage box 27 can be cleaned. In fact, the length of the second impurity storage box 27 exceeds the lower side of the scratch plate mounting block 24, which can make the impurities scraped off by the impurity scratch plate 25 fall completely into the second impurity storage box 27, increasing the stability of the device when in use, and the set pull block 32 also makes the second impurity storage box 27 easy to draw out, increasing the convenience of the device when in use.

[0025] Furthermore, a motor mounting box 23 is fixedly installed in the hydrolysis impurity box 3, a rotating motor 21 is fixedly installed in the motor mounting box 23, a blocking triangle plate 33 is fixedly installed at the upper left end of the hydrolysis impurity box 3, the blocking triangle plate 33 is located at the lower side of the connection between the hydrolysis impurity box 3 and the fine filter adsorption layer mounting tube 9, and the hydrolyzed liquid in the hydrolysis impurity box 3 does not exceed the blocking triangle plate 33. The hydrolysis liquid for filtering impurities in the exhaust gas is contained in the hydrolysis impurity box 3, and the structure can use the temperature of the hydrolysis liquid to dissipate the heat of the rotating motor 21, and at the same time, the structure can effectively use the space in the hydrolysis impurity box 3, so that the overall volume of the equipment is reduced, thereby making the equipment more convenient to carry, and the blocking triangle plate 3 can prevent the hydrolyzed liquid in the hydrolysis impurity box 3 from entering the fine filter adsorption layer mounting tube 9 to a certain extent, thereby increasing the adaptability and stability of the equipment when in use.

[0026] Furthermore, the condensation impurity removal box 1 is connected to the center of the left side of the hydrolysis impurity removal box 3 through the first connecting water pipe 34, and the condensation impurity removal box 1 is connected to the lower right end of the hydrolysis impurity removal box 3 through the second connecting water pipe 35. This structure allows the hydrolyzed liquid in the condensation impurity removal box 1 and the hydrolysis impurity removal box 3 to circulate with each other, and because the temperature of the hydrolyzed liquid is used in the condensation impurity removal box 1 and the chemical properties of the hydrolyzed liquid are used in the hydrolysis impurity removal box 3, this structure can make efficient use of the hydrolyzed liquid, optimizing the purification structure of the equipment.

[0027] Furthermore, a mounting thread ring 36 is fixedly installed on the hydrolysis impurity box 3 and is in communication with the hydrolysis impurity box 3. A mounting thread ring 37 is provided on the rear side of the fine filter adsorption layer mounting tube 9 and is matched with the mounting thread ring 36. The fine filter adsorption layer mounting tube 9 is fixedly installed on the mounting thread ring 36 through the mounting thread ring 37. An impurity adsorption filter layer 38 is fixedly installed in the array on the fine filter adsorption layer mounting tube 9. An anti-sliding block 39 is fixedly installed inside the fine filter adsorption layer mounting tube 9. This structure enables the device to have the ability of fine filtering, so that the exhaust gas after condensation, coarse filtering and hydrolysis is finally filtered. Moreover, since the exhaust gas has undergone three filtering procedures, the large particles of impurities inside have been removed when the fine filtering is finally performed, so that the service life of the anti-sliding block 39 is longer, and the anti-sliding block 39 can also be conveniently replaced, which increases the functionality of the device when it is used.

[0028] Working principle: When in use, unscrew the water inlet threaded plug 11, inject hydrolyzed liquid into the condensation and impurity removal box 1, so that the hydrolyzed liquid fills the condensation and impurity removal box 1, and the hydrolyzed liquid also fills the hydrolyzed impurity removal box 3 through the first connecting water pipe 34 and the second connecting water pipe 35. The highest height of the hydrolyzed liquid cannot exceed the height of the blocking triangle plate 33, and then screw the exhaust gas discharge pipe at the exhaust gas inlet connecting pipe 4. The exhaust gas enters the condensation connecting pipe 5. First, the exhaust gas will be condensed due to the temperature difference between the exhaust gas itself and the hydrolyzed liquid. Part of the impurities will follow the shape of the condensation connecting pipe 5 and enter the first impurity storage box 15 to be collected, and then the exhaust gas will pass through the exhaust gas discharge inclined pipe 6 and the coarse filter active filter disc 7 to be discharged. At this time, the coarse filter active filter disc 7 will intercept impurity particles with larger diameters due to its own aperture. At this time, the impurity particles will adhere to the coarse filter active filter disc 7, and then the rotating motor 21 will be started. The rotation of the output shaft of the rotating motor 21 will drive the driving gear 22 to rotate. The driving gear 22 drives the coarse filter active filter disc 7 to rotate through the engagement between the gear ring 20, so that The part of the coarse filter active filter disc 7 that filters the exhaust gas can be replaced. During the rotation of the coarse filter active filter disc 7, the impurity scratching plate 25 rubs against the surface of the coarse filter active filter disc 7, so that the impurities on the surface of the coarse filter active filter disc 7 can fall into the second impurity storage box 27 under the scratching of the impurity scratching plate 25. The exhaust gas filtered by the coarse filter active filter disc 7 enters the exhaust gas discharge L-shaped pipe 8. The gas emerges from the lower side of the exhaust gas discharge L-shaped pipe 8, is filtered by the hydrolyzate, and then enters the fine filter adsorption layer installation pipe 9. The anti-sliding block 39 in 9 is discharged after filtering. When disassembling the first impurity storage box 15, the first screw 17 is unscrewed, and then the storage box holding block 19 is hooked to make the first impurity storage box 15 be pulled out. When the second impurity storage box 27 needs to be disassembled, the second screw 31 is unscrewed, and then the pulling block 32 is hooked to make the second impurity storage box 27 be pulled out. When disassembling the fine filter adsorption layer mounting tube 9, the fine filter adsorption layer mounting tube 9 can be directly rotated to make the fine filter adsorption layer mounting tube 9 detach from the mounting threaded ring 36. The above is the entire working principle of the present invention.

[0029] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
