Through effective cooling and purification processes, it reduces the impact of flue gas on the environment, especially in thermal power generation and chemical industries, where the flue gas generated during the combustion of equipment contains a lot of heat and pollutants.

[0003] The existing flue gas cooling treatment first passes through a cooling treatment tower for cooling and water washing. This step can effectively reduce the temperature of the flue gas and remove some pollutants. The flue gas then enters a pretreatment tower for desulfurization and purification, further reducing harmful substances such as sulfur oxides in the flue gas. This process is of great significance for reducing air pollution and improving environmental quality.

[0034] When in use, first connect the smoke duct with the smoke inlet 4, and under the action of the external induced draft fan, the smoke enters the interior of the cooling dust removal tower 1 through the smoke inlet 4, then connect the external water washing liquid with the connecting water pipe 7, and then continuously spray the interior of the cooling dust removal tower 1 through multiple spraying parts 6. The flue gas entering the cooling dust removal tower 1 will gradually rise after entering the cooling dust removal tower 1 according to the principle of hot air rising, so that it will come into contact with the continuously sprayed water washing liquid. At this time, the flue gas will be rapidly cooled by contact with the water washing liquid, and at the same time, the trace large particles of dust entrained in the gas will be washed away by the falling water washing liquid, so that the large The particulate dust and the sprayed washing liquid fall to the bottom of the cooling and dust removal tower 1 together due to the influence of gravity.

In addition, when the large dust particles and the sprayed water washing liquid fall downward under the influence of gravity, they will contact the filter plate 8 inside the cooling dust removal tower 1, so that the large dust particles and the water washing liquid are separated by filtering through the filter plate 8, so that the large dust particles remain on the surface of the filter plate 8, and the water washing liquid will remain on the guide plate 28 at the bottom of the cooling dust removal tower 1 after filtering. Since the flue gas temperature is as high as 120°C, the flue gas will quickly lift the sprayed water washing liquid after entering the cooling dust removal tower 1. Temperature, at this time, the pump 29 can be started to operate to extract the high-temperature water washing liquid after filtering on the drainage plate 28, and then enter the water cooler 30 through the guidance of the connecting pipe 1 31.

In the process of the operation of the cleaning component, the auxiliary component will also be driven to operate together. The auxiliary component can be used to intermittently shake the filter plate 8 to shake out some large particles of dust remaining inside the filter plate 8, thereby greatly improving the cleaning effect of the filter plate 8.

A scraper 16 is slidably connected inside the adjusting block 15. A plurality of springs 17 are evenly and fixedly connected inside the adjusting block 15. One end of the plurality of springs 17 away from the inner wall of the adjusting block 15 is fixedly connected to the top of the scraper 16. A pressure sensor 33 is fixedly connected to one side of the interior of the cooling and dust removal tower 1. The pressure sensor 33 is electrically connected to an external controller, and the pressure sensor 33 and the water retaining frame 11 are on the same horizontal line.

[0036] When in use, first start the servo motor 10 to drive the screw 9 to rotate. At this time, the water retaining frame 11 will reciprocate on the screw 9 through the guidance of the guide rod 12, thereby driving the scraper 16 at the bottom to move, and the elastic ejection of the spring 17 will enable the scraper 16 to always fit the surface of the filter plate 8 during the movement. Through the continuous movement of the scraper 16, the large particles of dust on the surface of the filter plate 8 will be scraped and cleaned.

When it reaches the initial position, the electric telescopic rod 14 can be operated again to make the scraper 16 and the filter plate 8 fit together again. Through the above-mentioned reciprocating operation, the surface of the filter plate 8 can be cleaned in a cycle while avoiding the accumulation of large particles of dust on the end of the filter plate 8 away from the collection component during the reciprocating cleaning process.

[0037] Reference Figure 3 and Figure 4 The auxiliary component includes a rotating shaft 18 rotatably connected to the inside of the cooling dust removal tower 1, the rotating shaft 18 is located below the filter plate 8, and two cams 19 are symmetrically fixedly connected to the rotating shaft 18. The protruding ends of the two cams 19 can fit with the bottom surface of the filter plate 8. One end of the screw rod 9 is fixedly connected to a pulley 1 20, and one end of the rotating shaft 18 is fixedly connected to a pulley 21. A connecting belt 22 is sleeved on the pulley 1 20 and the pulley 2 21.

[0038] During use, when the servo motor 10 drives the screw rod 9 to rotate, it will also drive the pulley 1 20 to rotate. At this time, the pulley 21 will be driven to rotate together through the guidance of the connecting belt 22. The guide of the pulley 21 will make the rotating shaft 18 drive the cam 19 to continuously rotate inside the cooling and dust removal tower 1. At this time, through the rotation of the cam 19, the protruding end will intermittently contact the bottom of the filter plate 8, so that the filter plate 8 can be intermittently shaken inside the cooling and dust removal tower 1. Some large particles of dust remaining in the filter plate 8 can be shaken out through intermittent shaking, which is convenient for the scraper 16 to perform more comprehensive cleaning, thereby greatly improving the cleaning effect of the filter plate 8.

[0040] During use, when the scraper 16 pushes the large particles of dust to fit into the cooling dust removal tower 1, the baffle 24 will be pushed by one side of the adjustment block 15, so that the large particles of dust will fall into the interior of the collection box 26 through the drain outlet 23. When the collection box 26 is full, the collection box 26 can be lifted, and the block 27 can be separated from the snap ring 25, so that the collection box 26 can be easily cleaned, which greatly improves the convenience of cleaning.

[0041] The implementation principle of the flue gas cooling treatment system of this embodiment is as follows: when in use, the flue gas duct is first connected to the smoke inlet 4, and under the action of the external induced draft fan, the smoke enters the interior of the cooling dust removal tower 1 through the smoke inlet 4, and then the external water washing liquid is connected to the connecting water pipe 7, and then the interior of the cooling dust removal tower 1 is continuously sprayed through multiple spraying parts 6. The flue gas entering the cooling dust removal tower 1 will gradually rise after entering the cooling dust removal tower 1 according to the principle of hot air rising, so it will come into contact with the continuously sprayed water washing liquid. At this time, the flue gas will be rapidly cooled by contact with the water washing liquid, and at the same time, the trace large particles of dust entrained in the gas will also be removed by the falling water washing liquid. The pretreatment tower 2 is cleaned by washing, so that the large dust particles and the sprayed washing liquid fall to the bottom of the cooling and dust removal tower 1 under the influence of gravity. After the preliminary cooling and dust removal, the flue gas will enter the interior of the pretreatment tower 2 through the smoke pipe 3. At this time, the external desulfurization solution can be connected to the connecting water pipe 7 on one side of the pretreatment tower 2, so that the desulfurization solution is sprayed through the multiple spraying parts 6 inside the pretreatment tower 2. Therefore, the flue gas entering the pretreatment tower 2 will be in countercurrent contact with the desulfurization solution flowing from top to bottom, so that the sulfur dioxide and nitrogen dioxide in the flue gas are absorbed by the solvent. Finally, after washing and desulfurization, the flue gas is purified and released from the smoke outlet 5 at the top of the desulfurization water washing tower to the absorption and desorption section. In addition, when the large dust particles and the sprayed water washing liquid fall downward under the influence of gravity, they will contact the filter plate 8 inside the cooling dust removal tower 1, so that the large dust particles and the water washing liquid are separated by filtering through the filter plate 8, so that the large dust particles remain on the surface of the filter plate 8, and the water washing liquid will remain on the guide plate 28 at the bottom of the cooling dust removal tower 1 after filtering. Since the flue gas temperature is as high as 120°C, the flue gas will quickly lift the sprayed water washing liquid after entering the cooling dust removal tower 1. Temperature, at this time, the pump 29 can be started to operate to extract the high-temperature water washing liquid after filtering on the drainage plate 28, and then enter the water cooler 30 through the guidance of the connecting pipe 1 31. The water washing liquid can be quickly cooled by the operation of the water cooler 30, and the cooled water washing liquid will be guided by the connecting pipe 2 32 and then flow into the connecting water pipe 7 again and sprayed out through the spraying part 6, so as to realize the cooling and recycling of the water washing liquid, reduce the waste of water resources and environmental pollution, and reduce the water treatment cost of the enterprise; Secondly, when large particles of dust continue to fall on the filter plate 8, the filter plate 8 may gradually become blocked. Therefore, the servo motor 10 can be started to drive the screw rod 9 to rotate. At this time, the water retaining frame 11 will reciprocate on the screw rod 9 through the guidance of the guide rod 12, thereby driving the scraper 16 at the bottom to move, and the elastic ejection of the spring 17 will enable the scraper 16 to always fit with the surface of the filter plate 8 during the movement. Through the continuous movement of the scraper 16, the large particles of dust on the surface of the filter plate 8 will be scraped and cleaned. When the water retaining frame 11 drives the scraper 16 to continue to move to one side of the cooling dust removal tower 1, it will fit with the pressure sensor 33. After the pressure sensor 33 is pressurized, it will immediately transmit the signal to the external controller, and then the electric telescopic rod 14 will be started to drive the adjustment block 15 to rise, thereby driving the scraper 16 to gradually move away from the filter plate 8. At this time, the servo motor 10 can be reversed to operate, and the water retaining frame 11 can be driven back to the cooling dust removal tower 1 through the guidance of the screw rod 9. The scraper 16 and the filter plate 8 are in a state of being moved in a circular motion, and the filter plate 8 is moved in a direction of rotation ... Finally, when the scraper 16 pushes the large dust particles to fit the cooling dust removal tower 1, the baffle 24 will be pushed by one side of the adjustment block 15, so that the large dust particles will fall into the interior of the collection box 26 through the sewage outlet 23. When the collection box 26 is full, the collection box 26 can be lifted, and the clamping block 27 can be separated from the clamping ring 25, so that the collection box 26 can be easily cleaned, which greatly improves the convenience of cleaning.
