Description

Technical Field

[0001] This utility model relates to the field of integrated treatment equipment technology, specifically an integrated flue gas denitrification and desulfurization treatment equipment. Background Technology

[0002] Integrated treatment equipment is a device that can simultaneously treat nitrogen oxides and sulfur dioxide in flue gas to reduce their emissions and mitigate environmental pollution.

[0003] Common integrated treatment equipment typically uses kilns to generate high-temperature flue gas, removes acidic components such as sulfur dioxide from the flue gas through dry desulfurization towers, and stores the dust in ash silos.

[0004] However, because the desulfurizing agent reacts with acidic components such as sulfur dioxide in the flue gas, it produces solid substances such as calcium chloride, calcium sulfite, and calcium sulfate. These substances adhere to the tower wall, forming dust accumulation. The dust accumulation inside the desulfurization tower will block the contact channel between the desulfurizing agent and the flue gas, preventing the desulfurizing agent from fully contacting the acidic components such as sulfur dioxide in the flue gas and reducing the desulfurization efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an integrated flue gas denitrification and desulfurization treatment device to solve the problem mentioned in the background technology that dust accumulation in the desulfurization tower will block the contact channel between the desulfurizing agent and the flue gas, resulting in the desulfurizing agent not being able to fully contact the acidic components such as sulfur dioxide in the flue gas, thus reducing the desulfurization efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution: an integrated flue gas denitrification and desulfurization treatment device. Please refer to [link / reference]. Figure 1 It includes a kiln 1, a flue gas pipe 2 installed at the outlet of the kiln 1, a desulfurization tower 3 on the surface of the kiln 1, and the outlet end of the flue gas pipe 2 connected to the inlet end of the desulfurization tower 3.

[0029] Storage tank 4 is located at the bottom of desulfurization tower 3. Please refer to [link / reference]. Figure 2 The upper surface of the desulfurization tower 3 is equipped with a drive motor 5. Please refer to [link / reference]. Figure 5 The rotor output end of the drive motor 5 is equipped with a first gear 6, and the surface of the first gear 6 is meshed with a second gear 7.

[0030] Please see Figure 4 The lead screw 8 is located at the bottom of the second gear 7, and a cleaning bracket 9 is screwed onto the surface of the lead screw 8. Please refer to [link / reference]. Figure 6 A vibration motor 10 is installed in the groove on the surface of the cleaning rack 9;

[0031] Vibration motor 10 is a ZFB type bin vibrator, which is widely used in industries such as power, building materials, coal, mining, chemical, metallurgy, casting, light industry, food, pharmaceutical, grain, and transportation to prevent and eliminate blockage phenomena such as arching, tubular channels, and sticking of materials in bins, tanks, or hoppers.

[0032] Starting the drive motor 5 drives the first gear 6 to rotate, which in turn drives the second gear 7 to rotate, which in turn drives the lead screw 8 to rotate. The cleaning frame 9 also rotates to scrape off the dust adsorbed on the inner wall of the desulfurization tower 3. At the same time, starting the vibration motor 10 generates a large vibration force, which drives the inner wall of the desulfurization tower 3 to vibrate, further cleaning the dust on the inner wall of the desulfurization tower 3. This allows the desulfurizing agent to fully contact the sulfur dioxide in the flue gas, improving the desulfurization efficiency of the device.

[0033] Please see Figure 1 The upper surface of the desulfurization tower 3 is equipped with a mounting bracket 11, please refer to [reference needed]. Figure 4 The surface of the desulfurization tower 3 is equipped with an installation plate 12, and the drive motor 5 is installed at the bottom of the mounting frame 11, so that the drive motor 5 can operate stably.

[0034] Please see Figure 5 The upper surface of the second gear 7 is equipped with a first turntable 13, and the outer side of the first turntable 13 is provided with a second turntable 14. The bottom of the second turntable 14 is also equipped with a lead screw 8. The lead screw 8 is screwed to the surface of the cleaning frame 9, so that the lead screw 8 can stably drive the cleaning frame 9 to rise and fall.

[0035] A belt 15 is connected between the first turntable 13 and the second turntable 14. The first turntable 13 can drive the second turntable 14 to rotate through the belt 15, thereby driving the two lead screws 8 to rotate synchronously.

[0036] The upper surfaces of the second turntable 14 and the second gear 7 are both mounted to the bottom of the mounting bracket 11 via bearings, and the bottom of the first gear 6 is mounted to the upper surface of the mounting plate 12 via bearings, so that the first gear 6, the second gear 7 and the second turntable 14 can rotate stably.

[0037] Please see Figure 2 A funnel 16 is installed in the lower part of the inner cavity of the desulfurization tower 3, and the bottom end of the screw 8 is mounted to the bottom of the inner cavity of the desulfurization tower 3 via bearings. Please refer to [link / reference]. Figure 3 The storage box 4 has a drawer 17 inserted inside. The dust that has been cleaned can be transported into the storage box 4 through the funnel 16. The dust can be easily removed from the storage box 4 by pulling out the drawer 17.

[0038] In operation, the following steps are taken: First, the drive motor 5 is started, which drives the first gear 6 to rotate, thereby driving the second gear 7 to rotate. The second gear 7 drives the first turntable 13 to rotate, and the first turntable 13 drives the second turntable 14 to rotate via the belt 15, thereby driving the two lead screws 8 to rotate synchronously. Then, the cleaning frame 9 also rotates to scrape off the dust adsorbed on the inner wall of the desulfurization tower 3. At the same time, the vibration motor 10 is started to generate a large vibration force, thereby driving the inner wall of the desulfurization tower 3 to vibrate, which can further clean the dust on the inner wall of the desulfurization tower 3, so that the desulfurizing agent can fully contact the sulfur dioxide in the flue gas, improving the desulfurization efficiency of the device. Finally, the cleaned dust can be transported to the storage box 4 through the funnel 16, and the dust can be easily removed from the storage box 4 by pulling out the drawer 17.
