Technical Field

[0001] The invention relates to the technical field of flue gas emission, and in particular to a flue gas emission adsorption treatment device for a thermal boiler. Background Art

[0002] As an energy conversion device, the boiler consumes chemical energy and electrical energy in the fuel during operation and outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. However, a large amount of waste gas and flue gas will be generated during use. If these flue gases are directly discharged without treatment, they will cause serious pollution to the atmospheric environment. Therefore, the flue gas needs to be adsorbed and treated before discharge.

Although the above patent can treat the flue gas before discharging, since the flue gas mixture needs to pass through the filter cotton and then contact with the water mist to be washed with water, the water-soluble substances in the flue gas mixture are adsorbed and removed. During the falling process from top to bottom, it is difficult for part of the flue gas mixture to fully contact with the water mist to complete the water washing treatment, which affects the effect of the adsorption treatment.

[0004] The present invention aims to solve the problems existing in the above patents. To this end, a flue gas emission adsorption treatment device for thermal boilers is proposed, which can make the flue gas mixture fully and for a longer time contact with water to adsorb water-soluble substances and improve the adsorption treatment effect.

[0035] Initially, the connecting pipe 41 is connected to an external water source, and the pumping pipe 122 is connected to an external pumping machine. First, the air inlet pipe 3 is connected to the specified position of the thermal boiler, and the driving motor 121 is started to rotate. The driving motor 121 drives the filter cartridge 12 to rotate, and the rotation of the filter cartridge 12 drives the collecting cartridge 126 to move in a circular motion. At the same time, the rotation of the filter cartridge 12 also drives the guide gear ring 124 to move in a circular motion. The first outer gear ring 123 drives the circularly moving guide gear ring 124 to rotate. The rotation of the guide gear ring 124 drives the first spur gear 125 to rotate through the synchronous belt assembly. The rotation of the first spur gear 125 drives the second spur gear 127 to rotate. The rotation of the second spur gear 127 drives the collecting cartridge 126 to rotate. The collecting cartridge 126 rotates with the rotation of the filter cartridge 12, which makes The opening of the collecting cylinder 126 is always in an upward state, and at the same time, the rotation of the filter cylinder 12 drives the outer second outer ring gear 129 to rotate. The rotation of the outer second outer ring gear 129 drives the inner second outer ring gear 129 to rotate through the gear shaft 1210. The rotation of the inner second outer ring gear 129 drives the spiral scraper 128 to rotate. When the flue gas mixture composed of ozone and flue gas is discharged into the intake pipe 3, the flue gas mixture in the intake pipe 3 is first discharged into the filter cylinder 12. The filter cylinder 12 first filters the particulate impurities in the flue gas mixture. The rotation of the spiral scraper 128 scrapes the particulate impurities filtered out by the filter cylinder 12 to the right. The scraped particulate impurities move to the right and fall into the collecting cylinder 126. The collecting cylinder 126 drives the particulate impurities to rotate to the top and face the extraction pipe 122 When necessary, the extraction pipe 122 extracts the particulate impurities in the collecting tube 126 for collection and treatment. In this way, it can prevent the flue gas mixture from being mixed with a large amount of particulate impurities and affecting the subsequent treatment, thereby facilitating the subsequent treatment of the flue gas mixture. The flue gas mixture after filtering the particulate impurities is discharged into the tower body 1. At this time, water is discharged into the connecting pipe 41, and the water in the connecting pipe 41 is discharged into the water mist nozzle 4. The water mist nozzle 4 atomizes the water and sprays it out. The water mist falls downward and contacts the filter cotton 7. The water mist wets the filter cotton 7, making the filter cotton 7 moist. At the same time, part of the water in the connecting pipe 41 is discharged into the annular water spray pipe 10, and the annular water spray pipe 10 sprays water into the movable frame 9. As the water is continuously sprayed in, the water in the movable frame 9 overflows and falls into the tower body 1. When the water accumulated in the tower body 1 passes over When the guide pipe 31 is installed, the guide pipe 31 can be connected to an external machine so that the water surface height accumulated in the tower body 1 is always at the same height. As the smoke mixture continuously flows downward, the smoke mixture contacts the water mist, and the water mist contacts the smoke mixture, so that the water washing treatment of the smoke mixture can be completed first, and then the smoke mixture continues to flow through the filter cotton 7 and is discharged through the porous frame 6. The electric rotating shaft 5 is started, and the electric rotating shaft 5 drives the middle bevel gear 113 to rotate. The rotation of the middle bevel gear 113 drives the left and right bevel gears 113 to rotate. The left and right bevel gears 113 drive the left and right discs 111 to rotate. The rotation of the left and right discs 111 drives the left and right connecting rods 112 to move up and down. The up and down movement of the connecting rods 112 drives the movable frame 9 to move up and down.The movable frame 9 drives the annular water spray pipe 10 and water to move up and down. When the movable frame 9 moves upward and contacts the porous frame 6, the movable frame 9 covers the lower half of the porous frame 6, and the flue gas mixture discharged from the porous frame 6 contacts the water in the movable frame 9. Since the movable frame 9 covers the lower half of the porous frame 6, the discharged flue gas mixture can fully contact the water in the movable frame 9 to adsorb water-soluble substances in the flue gas mixture, so as to prevent the flue gas mixture from not fully contacting with the water to complete the adsorption treatment, thereby improving the effect of the adsorption treatment. The water-soluble substances in the flue gas mixture are adsorbed, and the denitration treatment of the flue gas mixture is completed. When the movable frame 9 moves downward, the movable frame 9 drives the annular water spray pipe 10 and water to move downward, and the movable frame 9 moves downward and breaks contact with the porous frame 6. The movable frame 9 stops covering the lower half of the porous frame 6, and the flue gas mixture after adsorption continues to move downward. The water flows into the exhaust pipe 2, and the exhaust pipe 2 discharges the flue gas mixture after adsorption treatment. The treated flue gas mixture will not cause serious pollution to the atmospheric environment. When the flue gas mixture has completed the adsorption treatment, stop discharging water into the connecting pipe 41, the water mist nozzle 4 and the annular water spray pipe 10 stop spraying water, and the water in the tower body 1 is discharged through the guide pipe 31. The external pumping machine is turned off, the pumping pipe 122 stops pumping, the drive motor 121 is turned off, the drive motor 121 stops driving the filter cartridge 12 to rotate, the filter cartridge 12 stops driving the collection cartridge 126 to rotate, and the filter cartridge 12 stops driving the spiral scraper 128 to rotate through the second outer gear ring 129 and the gear shaft 1210, and then the electric shaft 5 is turned off, the electric shaft 5 stops driving the disc 111 to rotate through the bevel gear 113, and the disc 111 stops driving the movable frame 9 to move up and down through the connecting rod 112.

The number of each set of fixed plates 135 is two. The two sets of fixed plates 135 are staggered with the three single-hole plates 13.

[0037] Initially, the circulating water tank 134 is filled with a proper amount of water. When the flue gas mixture of the filtered particulate impurities passes through the filter cartridge 12 and is discharged into the tower body 1, the circulating water tank 134 is started to discharge water into the cooling pipe 132 through the liquid outlet pipes 1331 on the left and right sides. The water flows in the cooling pipe 132, and the water in the cooling pipe 132 is discharged into the liquid inlet pipe 133. The water in the liquid inlet pipe 133 is discharged back to the circulating water tank 134 to be used again. This is repeated, and the water can be continuously circulated, so that the flue gas mixture flows downward. When the flue gas mixture flows through the upper single hole plate 13, the flue gas mixture contacts the heat sink fins 131, and the heat sink fins 131 cool the flue gas mixture. The cooling tubes 132 absorb the heat on the heat sink fins 131 to prevent the heat sink fins 131 from overheating and affecting the subsequent cooling effect of the flue gas mixture, thereby ensuring the normal cooling effect of the heat sink fins 131, and then completing the heat dissipation of the heat sink fins 131. Then, the flue gas mixture continues to flow. Since the hole of the middle single hole plate 13 is on the left, the flue gas mixture The flue gas mixture flows to the lower left through the middle single-hole plate 13, and then flows to the lower right through the lower single-hole plate 13, and this process is repeated. The flue gas mixture flows through the S-shaped guide channel formed by the three single-hole plates 13 and is cooled. Due to the S-shaped guide channel formed by the three single-hole plates 13, the flue gas mixture can be in contact with the heat sink fins 131 for a longer time and be cooled. The cooled flue gas mixture continues to flow downward for subsequent adsorption treatment. At the same time, the electric shaft 5 rotates to drive the rotating frame 137 to rotate, and the rotation of the rotating frame 137 drives the inner gear ring 138 to rotate. The rotation of the inner gear ring 138 drives the guide gear 136 to rotate. The rotation of the guide gear 136 drives the rotating blades 139 to rotate through the synchronous belt assembly. The rotation of the rotating blades 139 can blow the flue gas mixture downward, thereby blowing and guiding the flue gas mixture, so that the flue gas mixture can be more evenly in contact with the heat sink fins 131 and be cooled. When the adsorption treatment of the flue gas mixture is completed, the circulating water tank 134 is closed and the water stops circulating. In this way, it is possible to prevent the temperature of the flue gas mixture from being too high, which is not conducive to the adsorption treatment, thereby ensuring the effect of the subsequent adsorption treatment of the flue gas mixture.

[0038] See also Fig.11 As shown, the flue gas emission adsorption treatment device for a thermal boiler also includes an activated carbon plate 14 and a cover plate 15. The activated carbon plates 14 are evenly spaced and clamped at the lower part of the exhaust pipe 2. When the flue gas mixture contacts the activated carbon plates 14, the activated carbon plates 14 can purify the flue gas mixture. The cover plate 15 is rotatably connected to the lower right part of the exhaust pipe 2, and the cover plate 15 can block the activated carbon plate 14.

[0039] When the flue gas mixture is discharged into the exhaust pipe 2, the flue gas mixture contacts the activated carbon plate 14, and the activated carbon plate 14 can purify the flue gas mixture. The purified flue gas mixture is discharged from the exhaust pipe 2, so that harmful substances in the flue gas mixture can be prevented from affecting the surrounding environment, thereby ensuring a good surrounding environment.
