Description

Technical Field

[0001] This invention relates to the field of waste gas purification, specifically to an organic waste gas purification and treatment device. Background Technology

[0002] Organic waste gas generally refers to volatile organic compounds containing carbon (except for special cases such as methane) that are easily volatilized under normal temperature and pressure. The core criteria for its determination include volatility and chemical structure. Common volatile organic waste gases include benzene series compounds, petroleum hydrocarbon compounds, organochlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, and acids.

[0003] Activated carbon adsorption is a highly effective purification method for treating organic waste gas and odors. Activated carbon has a highly developed pore structure and a huge specific surface area, which can adsorb harmful substances in VOC waste gas through intermolecular van der Waals forces. Through efficient activated carbon adsorption, harmful substances in waste gas can be effectively removed.

[0004] In existing technologies, the purification of organic waste gas involves using a fan to drive the waste gas through an activated carbon treatment box under negative pressure. The purified waste gas is then discharged through a chimney by the fan. However, during use and observation, it was found that this purification method does not remove powdery impurities contained in the waste gas, thereby increasing the burden on the activated carbon during the adsorption and treatment of the waste gas and accelerating the frequency of activated carbon replacement.

[0005] Therefore, an organic waste gas purification and treatment device is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: An organic waste gas purification and treatment device according to this invention includes a base, a fan assembly fixedly installed on the top of the base; an exhaust assembly is provided on one side of the fan assembly, and the output end of the fan assembly and the exhaust assembly are connected; the exhaust assembly is fixedly installed on the top of the base; an adsorption mechanism is provided on the top of the base; the adsorption mechanism is used to remove pollutants from the waste gas; a pretreatment mechanism is provided on the top of the base; the pretreatment mechanism includes a first housing; the first housing is fixedly installed on the top of the base; a motor is fixedly connected to the top of the first housing; a first main pipe is rotatably connected through the top of the first housing; a belt is sleeved between the first main pipe and the motor output end; the bottom of the first main pipe... The system is connected to multiple first branch pipes; a nozzle is installed at the bottom of each first branch pipe; a second main pipe runs through one side of the first housing; multiple second branch pipes are connected to the end of the second main pipe; a first fitting is connected to the top of each second branch pipe; a drain pipe is connected to one end of the first housing; the input end of the fan assembly is connected to the adsorption mechanism via a pipe; the adsorption mechanism and the first housing are connected via a pipe. By setting up the first main pipe and first branch pipes, the waste gas can be pre-treated by spraying before the adsorption mechanism treats the waste gas, reducing dust in the waste gas and alleviating the burden on the activated carbon in the adsorption mechanism for waste gas treatment. At the same time, by setting up multiple first fittings and first branch pipes, the distribution and diffusion range of water and gas in the first housing are made more uniform, improving the dust reduction effect of water on the waste gas.

[0008] Preferably, the outer wall of the first pipe fitting is provided with a support; a frame is fixedly connected to the top of the support, and the frame is bent in multiple places; multiple water baffles are fixedly connected to the outer wall of the frame, and the water baffles are arranged in an inverted arc shape; adjacent water baffles are staggered; the outer wall of the frame is perforated, and the holes are located inside the water baffles; through the cooperation of the frame and the water baffles, the airflow is amplified by the water baffles after passing through the frame, further improving the airflow distribution range in the first box, while the water baffles can also appropriately guide the water flow range and reduce the intrusion of water into the first pipe fitting.

[0009] Preferably, a vertical pole is fixedly connected to the bottom of the first branch pipe; a connecting plate is fixedly connected to the top of the frame; multiple blades are fixedly connected to the outer wall of the connecting plate; the blades and the vertical pole are correspondingly arranged; the support and the first pipe are rotatably connected; through the cooperation of the vertical pole and the blades, when the first branch pipe rotates, the vertical pole will intermittently move the blades, so that the particulate impurities attached to the surface of the baffle plate due to dust reduction treatment will be accelerated to detach under the combined action of rotation and water impact, reducing the impurities remaining on the surface of the baffle plate. At the same time, the periodic rotation of the frame can also increase the air outlet range of the holes on the surface of the frame, thereby further expanding the baffle plate's guiding effect on the airflow.

[0010] Preferably, a tuning fork is fixedly connected to the top of the connecting plate; a rubber rod is fixedly connected to the outer wall of the upright; the rubber rod and the tuning fork are correspondingly arranged; through the cooperation of the rubber rod and the tuning fork, the rubber rod will rotate with the upright and periodically strike the tuning fork, and the tuning fork will vibrate at high frequency under the striking action, thereby further accelerating the removal speed and effect of impurities on the surface of the baffle plate. It is worth mentioning that since the rubber rod is located at the bottom of the first branch pipe, its surface temperature will not exceed its tolerance limit due to water cooling.

[0011] Preferably, a guide plate is fixed to the outer wall of the baffle plate; the guide plate is inclined and has a C-shaped structure; the bottom of the guide plate is perforated; by setting the guide plate, on the one hand, the airflow ejected from the inner wall frame of the baffle plate can directly enter the air duct formed by the baffle plate and the guide plate after being expanded by the baffle plate and flow to the top of the baffle plate, and can come into contact with the water flowing on the top of the baffle plate, so as to realize the forced dust reduction of the exhaust gas by the device; on the other hand, the opening at the bottom of the guide plate will not hinder the discharge of impurities washed and removed from the surface of the baffle plate, and avoid the accumulation of impurities inside the guide plate.

The block will be pushed under the action of the airflow pressure and the first spring will be compressed. At this time, part of the airflow will be discharged through the first pipe fitting, and another part of the airflow can be discharged through the second pipe fitting, reducing the pressure of the airflow at the first pipe fitting. In addition, the second pipe fitting and the first pipe fitting only differ in position, and the mechanism set at its top is the same as that of the first pipe fitting. It is worth mentioning that, due to the cooling effect of the spray water at the second branch pipe, the exhaust gas flowing in the second branch pipe can be cooled and heat exchanged to ensure that the temperature of the first spring does not exceed its bearing limit.

[0013] Preferably, reinforcing columns are fixedly connected between the outer walls of the frame; multiple reinforcing ribs are fixedly connected to the outer walls of the frame; by setting reinforcing ribs and reinforcing columns, additional support can be provided for the suspended parts of the frame surface, so as to reduce the uneven stress distribution caused by the bending structure when the frame rotates, and reduce material fatigue caused by long-term operation of the frame.

The particles enter the drawer through the wire mesh on one side and are removed by the adsorption unit. When one drawer has been working for a long time and its adsorption unit needs to be replaced, a winch can be started to raise and lower the gantry via a wire rope. The gantry will block the drawer that has been working for a long time and open the other drawer, enabling the device to replace the drawer online. The closed drawer can then be disassembled and replaced. Specifically, the drawer and the second housing are connected by bolts. By removing the bolts and sliding the drawer out, the adsorption unit inside can be replaced.

[0015] Preferably, the adsorption unit includes multiple shells; the outer wall of each shell is provided with a dovetail groove; a dovetail block is fixed to the outer wall of each shell; the dovetail block and the dovetail groove are arranged correspondingly; honeycomb activated carbon is placed inside each shell; a lifting assembly is provided inside each shell; by providing multiple shells in the pull-out box, and by connecting adjacent shells through the dovetail blocks and dovetail grooves, the multiple shells can form a tight whole, improving the stability and tightness of the adsorption unit installation, and also realizing the modularity of the adsorption unit, making it adaptable to the filling of different models of pull-out boxes. In addition, the shells can be pulled out by the lifting assembly, and the activated carbon inside the shells can be replaced after the lifting assembly is removed.

[0016] Preferably, the lifting assembly includes a rod; sliders are symmetrically slidably connected to the inner wall of the rod; a second spring is fixedly connected between the sliders and the inner wall of the rod; a pull rope is fixedly connected between the ends of a pair of sliders, and the pull rope and the rod are through-connected; the inner wall of the housing has a fixing groove corresponding to the sliders; when the housing is taken out of the pull box, it can be pulled out by pulling the handle at the top of the rod; when the lifting assembly needs to be disassembled, the pull rope can be pulled to pull the pair of sliders into the rod, at which time the second spring will be in a compressed state until the sliders slide out of the fixing groove in the housing, at which point the lifting assembly and the housing are disconnected, and the activated carbon inside the housing can be replaced after the lifting assembly is removed.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Specific implementation examples are given below.

[0035] Please see Figures 1 to 11As shown in the figure, an organic waste gas purification and treatment device according to an embodiment of the present invention includes a base 1, a fan assembly 12 fixedly installed on the top of the base 1; an exhaust assembly 13 is provided on one side of the fan assembly 12, and the output end of the fan assembly 12 and the exhaust assembly 13 are connected; the exhaust assembly 13 is fixedly installed on the top of the base 1; an adsorption mechanism is provided on the top of the base 1; the adsorption mechanism is used to remove pollutants in the waste gas; a pretreatment mechanism is provided on the top of the base 1; the pretreatment mechanism includes a first housing 14; the first housing 14 is fixedly installed on the top of the base 1; a motor 15 is fixedly connected to the top of the first housing 14; the... A first main pipe 16 is rotatably connected through the top of the first housing 14; a belt is fitted between the first main pipe 16 and the output end of the motor 15; multiple first branch pipes 17 are connected to the bottom of the first main pipe 16; nozzles are installed at the bottom of the first branch pipes 17; a second main pipe 18 is connected through one side of the first housing 14; multiple second branch pipes 19 are connected to the end of the second main pipe 18; a first fitting 110 is connected to the top of the second branch pipes 19; a drain pipe 111 is connected to one end of the first housing 14; the input end of the fan assembly 12 and the adsorption mechanism are connected by a pipe; the adsorption mechanism and the first housing 14 are connected by a pipe.

[0036] During operation, the fan assembly 12 can be started, connecting the second main pipe 18 at the pretreatment mechanism to the organic waste gas. The waste gas can then pass through the second main pipe 18 into the pretreatment mechanism and adsorption mechanism for treatment, and after passing through the fan assembly 12, enter the exhaust assembly 13 and be discharged. Specifically, the fan assembly 12 can be a centrifugal fan, and the exhaust assembly 13 is a common chimney. Therefore, both the fan assembly 12 and the exhaust assembly 13 are common existing technologies. Furthermore, the valves connecting the pipes between the above mechanisms are also mature technologies, and will not be elaborated further in the specification and drawings of this invention. Specifically, the waste gas enters each of the second branch pipes 19 and the first pipe fitting 110 through the second main pipe 18 and is evenly sprayed and diffused within the first housing 14. At this time, the motor 15 can be started to drive the first main pipe 16 to rotate via a belt. The top of the first main pipe 16 is connected to a water pump, allowing clean water to enter the first main pipe 16 through a pipe. When the first main pipe 16 rotates, it drives multiple first branch pipes 17 to rotate, allowing water to flow through the first main pipe 16 into the first branch pipes 17 and then be sprayed out through nozzles, reaching the bottom... The exhaust gas evenly sprayed from the first pipe 110 is cooled and dusted. Since the first pipe 110 is arranged in an array, the uniformity of exhaust gas distribution within the first chamber 14 is ensured. Simultaneously, the rotating spray of water from the first branch pipe 17 further improves the uniformity of clean water distribution within the first chamber 14, ensuring uniform contact between water and gas. Additionally, the valve at the drain pipe 111 should be open to discharge the wastewater from the first chamber 14 into a circulating treatment device for further purification; therefore, details are omitted here. The dust-suppressed exhaust gas can enter the adsorption mechanism under negative pressure and be activated. The activated carbon removes pollutants, and the purified gas can be transported to the exhaust assembly 13 through the fan assembly 12 and discharged from the top of the exhaust assembly 13. By setting the first main pipe 16 and the first branch pipe 17, the exhaust gas can be pre-treated by spraying before the adsorption mechanism treats the exhaust gas, reducing the dust in the exhaust gas and reducing the burden on the activated carbon in the adsorption mechanism for exhaust gas treatment. At the same time, by setting multiple first pipe fittings 110 and first branch pipes 17, the distribution and diffusion range of water and gas in the first box 14 are more uniform, improving the dust reduction effect of water on exhaust gas.

[0037] Please see Figures 3 to 7 As shown, the first pipe fitting 110 has a support 2 on its outer wall; the top of the support 2 is fixedly connected to a frame 22, and the frame 22 is bent in multiple places; the outer wall of the frame 22 is fixedly connected to multiple water baffles 23, and the water baffles 23 are inverted arc shape; the adjacent water baffles 23 are staggered; the outer wall of the frame 22 is perforated, and the holes are located inside the water baffles 23.

[0038] By setting up the baffle plate 23, after the gas is ejected from the first pipe 110, some of the gas will reach the bottom of the baffle plate 23 and diffuse in all directions under the guidance of its curved outer wall. This can also reduce the airflow velocity and increase the contact time between the airflow and the water. Another part of the airflow can enter the interior of the frame 22 and be ejected through the holes in the outer wall of the frame 22 during the flow. Since the holes are located inside the baffle plate 23, the airflow ejected here will also be amplified by the baffle plate 23. At the same time, by staggering the baffle plates 23, the first branch pipe 17 The water sprayed from the bottom falls onto the surface of the baffle plate 23 and flows between adjacent baffle plates 23, thereby guiding the water flow range and preventing the water from directly entering the second branch pipe 19 through the first pipe fitting 110. Through the cooperation of the frame 22 and the baffle plate 23, the airflow is amplified by the baffle plate 23 after being transmitted through the frame 22, further improving the airflow distribution range in the first box 14. At the same time, the baffle plate 23 can also appropriately guide the water flow range and reduce the intrusion of water into the first pipe fitting 110.

[0039] Please see Figures 4 to 7 As shown, the bottom of the first branch pipe 17 is fixedly connected to the upright 3; the top of the frame 22 is fixedly connected to the connecting plate 32; multiple blades 33 are fixedly connected to the outer wall of the connecting plate 32; the blades 33 and the upright 3 are arranged correspondingly; the support 2 and the first pipe fitting 110 are rotatably connected.

[0040] Through the combined action of the upright 3 and the blade 33, when the first branch pipe 17 rotates, the upright 3 intermittently moves the blade 33, causing the particulate impurities attached to the surface of the baffle plate 23 due to dust reduction treatment to be removed more quickly under the combined action of rotation and water impact, reducing the impurities remaining on the surface of the baffle plate 23. At the same time, the periodic rotation of the frame 22 can also increase the air outlet range of the holes on the surface of the frame 22, thereby further expanding the guiding effect of the baffle plate 23 on the airflow.

[0041] Please see Figure 4 and Figure 7 As shown, a tuning fork 42 is fixedly connected to the top of the connecting plate 32; a rubber rod 4 is fixedly connected to the outer wall of the upright 3; the rubber rod 4 and the tuning fork 42 are arranged correspondingly.

[0042] Through the combined action of the rubber rod 4 and the tuning fork 42, the rubber rod 4 will rotate together with the upright 3 and periodically strike the tuning fork 42. The tuning fork 42 will vibrate at high frequency under the impact, thereby further accelerating the removal speed and effect of impurities on the surface of the baffle plate 23. It is worth mentioning that since the rubber rod 4 is located at the bottom of the first branch pipe 17, its surface temperature will not exceed its tolerance limit due to water cooling.

[0043] Please see Figure 6 and Figure 7As shown, a guide plate 5 is fixed to the outer wall of the water baffle 23; the guide plate 5 is inclined and has a C-shaped structure; the bottom of the guide plate 5 is perforated.

[0044] By setting the guide plate 5, on the one hand, the airflow ejected from the inner wall frame 22 of the baffle plate 23 can directly enter the air duct formed by the baffle plate 23 and the guide plate 5 after being expanded by the baffle plate 23 and flow to the top of the baffle plate 23, so that it can come into contact with the water flowing on the top of the baffle plate 23, thereby achieving forced dust reduction of the exhaust gas by the device. On the other hand, the opening at the bottom of the guide plate 5 will not hinder the discharge of impurities washed and removed from the surface of the baffle plate 23, thus avoiding the accumulation of impurities inside the guide plate 5.

[0045] Please see Figure 7 As shown, a first spring 6 is fixedly connected to the end of the inner wall of the second branch pipe 19; a block 62 is fixedly connected to the end of the first spring 6, and the block 62 and the second branch pipe 19 are slidably connected; a second pipe fitting 63 is connected to the top of the second branch pipe 19, and the second pipe fitting 63 is located on top of the block 62.

[0046] Through the combined action of the first spring 6 and the block 62, when the speed of the fan assembly 12 increases, i.e., when the device is in a high-load working mode, the pressure of the gas in the second branch pipe 19 will increase. Under the action of the airflow pressure, the block 62 will be pushed and the first spring 6 will be compressed. At this time, part of the airflow will be discharged through the first pipe fitting 110, and another part of the airflow will be discharged through the second pipe fitting 63, reducing the pressure of the airflow at the first pipe fitting 110. In addition, the second pipe fitting 63 and the first pipe fitting 110 only differ in position. The mechanism set at its top is the same as that set at the first pipe fitting 110. It is worth mentioning that, due to the cooling effect of the spray water at the second branch pipe 19, the exhaust gas flowing in the second branch pipe 19 can be cooled and heat exchanged to ensure that the temperature of the first spring 6 does not exceed its bearing limit.

[0047] Please see Figure 7 As shown, reinforcing columns 72 are fixedly connected between the outer walls of the frame 22; multiple reinforcing ribs 7 are fixedly connected to the outer walls of the frame 22.

[0048] By setting up reinforcing ribs 7 and reinforcing columns 72, additional support can be provided for the suspended parts on the surface of the frame 22, so as to reduce the uneven distribution of stress caused by the bending structure when the frame 22 rotates, and reduce material fatigue caused by the frame 22 working for a long time.

[0049] Please see Figure 8 and Figure 9As shown, the adsorption mechanism includes a second housing 8; two pairs of pull-out boxes 86 are slidably fitted inside the second housing 8, and the two pairs of pull-out boxes 86 are arranged in upper and lower layers; an adsorption unit is provided on the inner wall of the pull-out box 86; a support frame 82 is fixedly connected to the top of the base 1; a winch 83 is fixedly connected to the top of the support frame 82; a steel wire rope 84 is fixedly connected to the output end of the winch 83; a pair of masts 85 are slidably fitted through the inner wall of the second housing 8; the pair of masts 85 are fixedly connected by a connecting rod; the top of one of the masts 85 is fixedly connected to the steel wire rope 84; a through groove is opened on the inner wall of the mast 85.

[0050] After the dust is settled, the gas enters the second chamber 8 and passes through the wire mesh on one side of the pull-out box 86, where it is cleaned by the adsorption unit. When one of the pull-out boxes 86 has been working for a long time and its adsorption unit needs to be replaced, the winch 83 can be started to raise and lower the gantry 85 via the wire rope 84. The gantry 85 will block the pull-out box 86 that has been working for a long time and open the other pull-out box 86, realizing the online replacement of the pull-out box 86. Then the closed pull-out box 86 can be disassembled and replaced. Specifically, the pull-out box 86 and the second chamber 8 are connected by bolts. By removing the bolts and sliding the pull-out box 86 out, the adsorption unit inside can be replaced.

[0051] Please see Figure 9 and Figure 10 As shown, the adsorption unit includes multiple shells 9; the outer wall of the shell 9 is provided with a swallow-shaped groove 93; a swallow-shaped block 92 is fixed to the outer wall of the shell 9; the swallow-shaped block 92 and the swallow-shaped groove 93 are arranged correspondingly; honeycomb activated carbon is placed inside the shell 9; and a lifting component is provided inside the shell 9.

[0052] By providing multiple housings 9 within the pull-out box 86, and by connecting adjacent housings 9 through dovetail blocks 92 and dovetail grooves 93, the multiple housings 9 can form a tight whole, improving the stability and tightness of the adsorption unit installation. At the same time, it also realizes the modularity of the adsorption unit, making it adaptable to the filling of different models of pull-out boxes 86. In addition, the housings 9 can be pulled out through the lifting assembly, and the activated carbon inside the housings 9 can be replaced after the lifting assembly is removed.

[0053] Please see Figure 11 As shown, the lifting assembly includes a rod 1001; sliders 1002 are symmetrically slidably connected to the inner wall of the rod 1001; a second spring 1004 is fixed between the sliders 1002 and the inner wall of the rod 1001; a pull rope 1003 is fixed between the ends of a pair of sliders 1002, and the pull rope 1003 and the rod 1001 are through-connected; the inner wall of the housing 9 has a fixing groove corresponding to the slider 1002.

[0054] When removing the housing 9 from the pull-out box 86, the housing 9 can be lifted out by pulling the handle at the top of the rod 1001. When it is necessary to disassemble the lifting assembly, the pull rope 1003 can be pulled to pull a pair of sliders 1002 into the rod 1001. At this time, the second spring 1004 will be in a compressed state until the sliders 1002 slide out of the fixing groove in the housing 9. At this time, the lifting assembly and the housing 9 are disconnected. After the lifting assembly is removed, the activated carbon in the housing 9 can be replaced.

[0055] Working principle: By activating the fan assembly 12 and connecting the second main pipe 18 of the pretreatment mechanism to the organic waste gas, the waste gas can enter the pretreatment mechanism and adsorption mechanism sequentially through the second main pipe 18, and then enter the exhaust assembly 13 after being treated by the fan assembly 12 and discharged by the exhaust assembly 13. The fan assembly 12 can be a centrifugal fan, and the exhaust assembly 13 is a common chimney. Therefore, both the fan assembly 12 and the exhaust assembly 13 are common existing technologies. In addition, the valves connecting the pipes between the above-mentioned mechanisms are also mature technologies, which will not be described in detail in the specification and drawings of this invention. Specifically, the waste gas enters each second branch pipe 19 and the first pipe fitting 110 through the second main pipe 18 and is evenly sprayed and diffused in the first box 14. At this time, the electric motor can be activated. Machine 15 drives the first main pipe 16 to rotate via a belt, connecting the top of the first main pipe 16 to a water pump so that cleaning water can enter the first main pipe 16 through the pipe. When the first main pipe 16 rotates, it drives multiple first branch pipes 17 to rotate as well. Water flows through the first main pipe 16 into the first branch pipes 17 and is then sprayed out through nozzles, cooling and reducing dust from the exhaust gas evenly sprayed from the bottom first pipe fitting 110. Because the first pipe fittings 110 are arranged in an array, the uniformity of exhaust gas distribution within the first housing 14 is ensured. Simultaneously, the rotating spraying of water from the first branch pipes 17 further improves the uniformity of cleaning water distribution within the first housing 14, ensuring uniform contact between water and gas. Additionally, the valve at the drain pipe 111 should be open to drain the first housing 14. 4. Wastewater is discharged into a recycling treatment device for further purification, so this will not be elaborated here. The dust-reduced exhaust gas can enter the adsorption mechanism under negative pressure and have pollutants removed by activated carbon. Finally, the purified gas can be transported to the exhaust assembly 13 via the fan assembly 12 and discharged from the top of the exhaust assembly 13. By setting a baffle plate 23, after the gas is ejected from the first pipe 110, some of the gas will reach the bottom of the baffle plate 23 and diffuse in all directions under the guidance of its curved outer wall. This also reduces the airflow velocity and increases the contact time between the airflow and the water. Another part of the airflow can enter the frame 22 and be ejected through the holes in the outer wall of the frame 22 during its flow. Since the holes are located inside the baffle plate 23, the airflow ejected here will also be amplified by the baffle plate 23. By staggering the water baffles 23, the water sprayed from the bottom of the first branch pipe 17 falls onto the surface of the water baffles 23 and flows between adjacent water baffles 23, thereby guiding the water flow range and preventing the water from directly entering the second branch pipe 19 through the first pipe fitting 110. Through the cooperation of the upright 3 and the blades 33, when the first branch pipe 17 rotates, the upright 3 intermittently moves the blades 33, causing the particulate impurities attached to the surface of the water baffles 23 due to dust reduction treatment to be accelerated to detach under the combined action of rotation and water impact, reducing the impurities remaining on the surface of the water baffles 23. At the same time, the periodic rotation of the frame 22 can also increase the air outlet range of the holes on the surface of the frame 22, thereby further expanding the guiding effect of the water baffles 23 on the airflow.Through the combined action of the rubber rod 4 and the tuning fork 42, the rubber rod 4 rotates with the upright 3 and periodically strikes the tuning fork 42. The tuning fork 42 vibrates at high frequency under the impact, thereby further accelerating the removal speed and effect of impurities on the surface of the baffle plate 23. It is worth mentioning that since the rubber rod 4 is located at the bottom of the first branch pipe 17, its surface temperature will not exceed its tolerance limit due to water cooling. By setting the guide plate 5, on the one hand, the airflow ejected from the inner wall frame 22 of the baffle plate 23 can directly enter the air duct formed by the baffle plate 23 and the guide plate 5 after being expanded by the baffle plate 23 and flow to the top of the baffle plate 23, where it can interact with the water flowing at the top of the baffle plate 23. Contact is made to achieve forced dust reduction of the exhaust gas by the device. On the other hand, the opening at the bottom of the guide plate 5 will not hinder the discharge of impurities washed and removed from the surface of the baffle plate 23, thus avoiding the accumulation of impurities inside the guide plate 5. Through the cooperation of the first spring 6 and the block 62, when the speed of the fan assembly 12 increases, that is, when the device is in a high-load working mode, the gas pressure in the second branch pipe 19 will increase. The block 62 will be pushed under the action of airflow pressure, and the first spring 6 will be compressed. At this time, part of the airflow will be discharged through the first pipe 110, and the other part of the airflow will be discharged through the second pipe 63, reducing the airflow at the first pipe 110. The pressure of the flow; in addition, the second pipe fitting 63 and the first pipe fitting 110 differ only in position, and the mechanism set at its top is the same as that of the first pipe fitting 110. It is worth mentioning that, due to the cooling effect of the sprayed water at the second branch pipe 19, the exhaust gas flowing in the second branch pipe 19 can be cooled and heat exchanged to ensure that the temperature of the first spring 6 does not exceed its bearing limit; by setting the reinforcing ribs 7 and reinforcing columns 72, additional support can be provided for the suspended parts on the surface of the frame 22, so as to reduce the uneven stress distribution caused by the bending structure when the frame 22 rotates, and reduce the material fatigue caused by the frame 22 working for a long time; after the dust is settled, the gas enters the second box 8. The material enters the pull-out box 86 through the wire mesh on one side and is removed by the adsorption unit. When one of the pull-out boxes 86 has been working for a long time and its adsorption unit needs to be replaced, the winch 83 can be started to raise and lower the gantry 85 via the wire rope 84. The gantry 85 will block the pull-out box 86 that has been working for a long time and open the other pull-out box 86, so that the device can replace the pull-out box 86 online. Then the closed pull-out box 86 can be disassembled and replaced. Specifically, the pull-out box 86 and the second box 8 are connected by bolts. By removing the bolts and sliding the pull-out box 86 out, the adsorption unit inside can be replaced.By providing multiple housings 9 within the pull-out box 86, and by connecting adjacent housings 9 through dovetail blocks 92 and dovetail grooves 93, the multiple housings 9 can form a tight whole, improving the stability and tightness of the adsorption unit installation. This also achieves modularity of the adsorption unit, allowing it to adapt to different models of pull-out boxes 86. Furthermore, the housing 9 can be pulled out using a lifting assembly. After removing the lifting assembly, the activated carbon inside the housing 9 can be replaced. When removing the housing 9 from the pull-out box 86, it can be lifted by pulling the handle at the top of the rod 1001. To disassemble the lifting assembly, the pull rope 1003 can be pulled to move a pair of sliders 1002 into the rod 1001. At this time, the second spring 1004 will be compressed until the sliders 1002 slide out of the fixing grooves inside the housing 9. At this point, the lifting assembly and housing 9 are disconnected. After removing the lifting assembly, the activated carbon inside the housing 9 can be replaced.
