Description

Technical Field

[0001] This invention relates to the field of exhaust gas treatment technology, and more particularly to an exhaust gas absorption system. Background Technology

[0002] Existing technologies employ a tail gas absorption system for tail gas treatment, which can significantly reduce tail gas emissions. However, due to the large volume of tail gas and the presence of organic matter mixed in it, these systems require treatment of the organic matter. Currently, activated carbon is commonly used for this purpose. However, the large volume and high flow rate of the tail gas mean that the gas has its own flow path, resulting in insufficient contact between the tail gas and the activated carbon, thus affecting the tail gas treatment efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies. The technology uses a tail gas absorption system to treat tail gas, which can greatly reduce tail gas emissions. However, in the use of existing tail gas absorption systems, due to the large volume of tail gas and the presence of organic matter mixed in the tail gas, it is necessary to treat the organic matter in the tail gas absorption system. Existing technologies generally use activated carbon as a means of treating organic matter. However, due to the large volume of tail gas and the fast flow rate during circulation, the tail gas has its own flow path, resulting in insufficient contact between the tail gas and the activated carbon, thus affecting the tail gas treatment efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a tail gas absorption system, comprising a desorption system, the desorption system including a water washing tower, a water removal mechanism, an organic matter removal mechanism, and a demisting mechanism. The water washing tower is used to receive tail gas, and the water washing solution in the water washing tower is provided by an alkaline solution. After the tail gas is treated by the water washing tower, it is treated by a water removal process, which is performed by water electrolysis. After the tail gas is treated by the water removal mechanism, it is treated by the organic matter removal mechanism, and then by the demisting process.

[0005] In a preferred embodiment, the organic matter removal mechanism includes a housing, a fixing plate on one side of the housing, an air inlet pipe embedded in one side of the fixing plate, a first filter tube on the inner wall of the housing, a second filter tube on the outer surface of the first filter tube, a third filter tube on the outer surface of the second filter tube, and a fourth filter tube on the outer surface of the third filter tube. A fixing ring is fixedly disposed between the outer surfaces of the first, second, third, and fourth filter tubes. The inner wall of the housing is fixedly connected to the outer surface of the fourth filter tube. A support plate is fixedly connected to one side of the housing, an air outlet pipe is fixedly embedded in one side of the support plate, and a connecting plate is fixedly connected between one end of the first, second, third, and fourth filter tubes. A control mechanism is disposed on one side of the connecting plate.

[0006] In a preferred embodiment, the control mechanism includes a transfer pipe, one side of which is rotatably connected to one side of a connecting plate, and a fixed pipe is fixedly connected to one side of the transfer pipe, one end of which is rotatably connected to one end of an air outlet pipe.

[0007] In a preferred embodiment, a fixing frame is fixedly connected to the outer surface of the adapter pipe, and a first gear is fixedly connected to the inner wall of the fixing frame.

[0008] In a preferred embodiment, a motor is fixedly mounted on one side of the connecting plate, and a second gear is fixedly connected to the output end of the motor, with the second gear meshing with the first gear.

[0009] In a preferred embodiment, the outer surface of the adapter pipe is fixedly connected to a plurality of connecting pipes, one end of the connecting pipe is fixedly connected to a rotating pipe, and one end of the rotating pipe is rotatably connected to a side hole pipe.

[0010] In a preferred embodiment, one end of the side hole tube is rotatably connected to a third gear.

[0011] In a preferred embodiment, the fourth filter tube is slidably connected to one side of the housing and to the outer surface of the side hole tube, and a fourth gear is fixedly connected to the outer surface of the fourth filter tube, and the fourth gear is meshed with the third gear.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0013] 1. In this invention, the incoming exhaust gas can be treated through the first filter tube, the second filter tube, the third filter tube, and the fourth filter tube. The first filter tube, the second filter tube, the third filter tube, and the fourth filter tube are all made of activated carbon. The first filter tube, the second filter tube, the third filter tube, and the fourth filter tube can adsorb the organic matter contained in the exhaust gas onto the first filter tube, the second filter tube, the third filter tube, and the fourth filter tube. At the same time, the first filter tube, the second filter tube, the third filter tube, and the fourth filter tube form a complex airflow hole, which can fully allow the exhaust gas to come into contact with the first filter tube, the second filter tube, the third filter tube, and the fourth filter tube, which can greatly increase the contact area between the exhaust gas and the first filter tube, the second filter tube, the third filter tube, and the fourth filter tube, thereby better absorbing the organic matter present in the exhaust gas.

[0014] 2. In this invention, the first gear and the second gear cooperate with each other, and the motor drives the second gear to rotate. In practical applications, the motor drives the adapter pipe to rotate, and the rotation of the adapter pipe drives multiple connecting pipes to rotate, thus enabling the rotating pipe to rotate. At the same time, through the rotational connection between the rotating pipe and the side hole pipe, the third gear and the fourth gear at one end of the side hole pipe cooperate with each other, so that when the side hole pipe rotates around the adapter pipe, the side hole pipe will rotate on its own axis. At this time, the direction of the side hole of the side hole pipe can be changed, thereby changing the gas flow rate inside the side hole pipe. At the same time, the rotation of the side hole pipe around the adapter pipe can make the gas inside the side hole pipe fully contact the inner wall of the side hole pipe. The material of the side hole pipe is the same as that of the first filter pipe, the second filter pipe, the third filter pipe and the fourth filter pipe, thereby further increasing the effect of removing organic matter.

[0025] 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.

[0026] Example 1

[0027] like Figure 1 As shown, the present invention provides a technical solution: an exhaust gas absorption system, including an absorption system 1, which includes a water washing tower, a water removal and organic matter removal mechanism 2, and a demisting mechanism. The water washing tower is used to receive exhaust gas, and the water washing solution in the water washing tower is provided by an alkaline solution. After the exhaust gas is treated by the water washing tower, it is treated by a water removal process, which is carried out by water electrolysis. After the exhaust gas is treated by the organic matter removal mechanism 2, it is then treated by the demisting mechanism.

[0028] Through the above embodiments, the exhaust gas is cleaned by a water washing tower, then the water-washed exhaust gas is electrolyzed to remove moisture, and then the organic matter contained in the exhaust gas is treated by the organic matter removal mechanism 2. Finally, the exhaust gas is demisted, thereby improving the emission standards of the exhaust gas.

[0029] Example 2

[0030] like Figure 1-6As shown, the organic matter removal mechanism 2 includes a housing 21. A fixing plate 22 is provided on one side of the housing 21. An air inlet pipe 23 is embedded and connected to one side of the fixing plate 22. A first filter pipe 24 is provided on the inner wall of the housing 21. A second filter pipe 25 is provided on the outer surface of the first filter pipe 24. A third filter pipe 26 is provided on the outer surface of the second filter pipe 25. A fourth filter pipe 27 is provided on the outer surface of the third filter pipe 26. A fixing ring 28 is fixedly provided between the outer surfaces of the first filter pipe 24, the second filter pipe 25, the third filter pipe 26 and the fourth filter pipe 27. The inner wall of the housing 21 is fixedly connected to the outer surface of the fourth filter pipe 27. A support plate 210 is fixedly connected to one side of the housing 21. An air outlet pipe 211 is fixedly embedded on one side of the support plate 210. A connecting plate 212 is fixedly connected between one end of the first filter pipe 24, the second filter pipe 25, the third filter pipe 26 and the fourth filter pipe 27. A control mechanism 29 is provided on one side of the connecting plate 212.

[0031] Through the above embodiments, the first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27 can treat the incoming exhaust gas. The first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27 are all made of activated carbon. The first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27 can adsorb the organic matter contained in the exhaust gas onto the first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27. At the same time, the first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27 form a complex airflow hole, which can fully allow the exhaust gas to come into contact with the first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27, which can greatly increase the contact area between the exhaust gas and the first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27, thereby better absorbing the organic matter present in the exhaust gas.

[0032] The control mechanism 29 includes a transfer pipe 291, one side of which is rotatably connected to one side of a connecting plate 212. A fixed pipe 296 is fixedly connected to one side of the transfer pipe 291, and one end of the fixed pipe 296 is rotatably connected to one end of an outlet pipe 211. A fixed frame 295 is fixedly connected to the outer surface of the transfer pipe 291, and a first gear 297 is fixedly connected to the inner wall of the fixed frame 295. A motor 298 is fixedly mounted on one side of the connecting plate 212, and a second gear 299 is fixedly connected to the output end of the motor 298. The second gear 299... The first gears 297 are meshed together. The outer surface of the adapter tube 291 is fixedly connected to multiple connecting tubes 292. One end of the connecting tube 292 is fixedly connected to the rotating tube 293. One end of the rotating tube 293 is rotatably connected to the side hole tube 294. One end of the side hole tube 294 is rotatably connected to the third gear 2910. The fourth filter tube 27 is slidably connected to one side of the housing 21 and the outer surface of the side hole tube 294. The outer surface of the fourth filter tube 27 is fixedly connected to the fourth gear 2911. The fourth gear 2911 and the third gear 2910 are meshed together.

[0033] Through the above embodiments, the first gear 297 and the second gear 299 cooperate with each other, and the motor 298 can drive the second gear 299 to rotate. Therefore, in practical applications, the motor 298 can drive the adapter pipe 291 to rotate. The rotation of the adapter pipe 291 will drive multiple connecting pipes 292 to rotate, thereby enabling the rotating pipe 293 to rotate. Simultaneously, through the rotatable connection between the rotating pipe 293 and the side-hole pipe 294, the third gear 2910 and the fourth gear 2911 at one end of the side-hole pipe 294 cooperate with each other, thereby enabling the side-hole pipe... When the side-hole tube 294 rotates around the adapter tube 291, it will rotate on its own axis. This changes the direction of the side hole of the side-hole tube 294, thereby changing the gas flow rate inside the side-hole tube 294. At the same time, the rotation of the side-hole tube 294 around the adapter tube 291 allows the gas inside the side-hole tube 294 to fully contact the inner wall of the side-hole tube 294. The side-hole tube 294 is made of the same material as the first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27, thereby further enhancing the effect of removing organic matter.

[0034] Working principle:

[0035] like Figure 1-6As shown, the exhaust gas undergoes water washing, water removal, and organic matter removal mechanism 2 treatment. The organic matter removal mechanism 2 and demisting treatment further enhance the emission effect. The exhaust gas enters the housing 21 through the intake pipe 23 and is treated by the first filter pipe 24, second filter pipe 25, third filter pipe 26, and fourth filter pipe 27. All four filter pipes are made of activated carbon, which adsorbs organic matter in the exhaust gas onto them. The complex airflow holes formed by these filter pipes ensure thorough airflow between the exhaust gas and the filter pipes. The contact between the third filter tube 26 and the fourth filter tube 27 greatly increases the contact area between the exhaust gas and the first filter tube 24, the second filter tube 25, the third filter tube 26, and the fourth filter tube 27, thereby better absorbing the organic matter present in the exhaust gas. Afterwards, the exhaust gas enters the interior of the side hole tube 294. When the side hole tube 294 rotates around the adapter tube 291, the side hole tube 294 will rotate, which changes the direction of the side hole of the side hole tube 294, thereby changing the gas flow rate inside the side hole tube 294. At the same time, the rotation of the side hole tube 294 around the adapter tube 291 allows the gas inside the side hole tube 294 to fully contact the inner wall of the side hole tube 294, thereby further increasing the effect of removing organic matter. Then, the exhaust gas passes through the adapter tube 293, the connecting tube 292, and the adapter tube 291 into the fixed tube 296 connected to the exhaust tube 211, and is finally discharged from the exhaust tube 211 for demisting treatment.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
