Description

Technical Field

[0001] This utility model relates to the field of deacidification tower technology, and in particular to a flue gas deacidification tower exhaust pipe. Background Technology

[0002] The exhaust pipe of the deacidification tower plays a crucial role in the flue gas deacidification process. It guides the deacidified flue gas out of the tower, ensuring that the purified flue gas is safely and effectively discharged into the atmosphere. The exhaust pipe is typically equipped with an atomizing disc, which atomizes the deacidification slurry, forming smaller droplets that are then sprayed onto the flue gas, effectively treating it for acid removal.

[0003] However, in actual processing, semi-dry atomizing discs are usually used. These atomizing discs have small volume and low rotation speed, resulting in large atomized slurry droplets that do not contact the flue gas sufficiently, which significantly reduces the deacidification effect. Therefore, this application proposes a flue gas exhaust pipe for a flue gas deacidification tower that can reduce the volume of atomized slurry droplets and thereby improve the deacidification effect. Utility Model Content

[0004] The purpose of this invention is to address the problem in the background technology that the semi-dry atomizing disc results in large slurry droplet particles, making it difficult for them to fully contact the flue gas. The invention proposes a flue gas exhaust pipe for a flue gas deacidification tower that can reduce the volume of atomized slurry droplet particles and thereby improve the deacidification effect.

[0028] Example

[0029] like Figures 1-4 As shown, this utility model proposes a flue gas exhaust pipe for a flue gas desulfurization tower, including a base 1. A flue gas concentrator 2 is fixedly installed on the top of the base 1, and an inlet pipe 3 is fixedly installed on the outer wall of the flue gas concentrator 2. Flue gas can be discharged into the flue gas concentrator 2 through the inlet pipe 3, facilitating subsequent desulfurization treatment. A sealing plate 4 is fixedly installed at the top of the flue gas concentrator 2. The sealing plate 4 has several circular openings 42 for dispersing flue gas. Several desulfurization spray pipes 5 are fixedly assembled on the top of the sealing plate 4. The bottom ends of the desulfurization spray pipes 5 are fixedly connected to the matching circular openings 42, ensuring that the flue gas in the flue gas concentrator 2 can be dispersed into multiple independent desulfurization spray pipes 5. The tops of the several desulfurization spray pipes 5 are jointly fixedly installed with... The motor mounting box 6 has several servo motors 62 arranged in a ring fixedly installed inside. The output end of the servo motor 62 is fixedly mounted with rotating blades 63. The bottom end of the rotating blades 63 extends into the deacidification spray pipe 5. The rotating blades 63 are driven by the servo motors 62 to rotate rapidly, which can break up the slurry sprayed into the deacidification spray pipe 5, ensuring that the slurry can be atomized into small droplets and can fully contact the flue gas. A flue gas emission pipe 9 is installed on one side of the deacidification spray pipe 5. The flue gas emission pipe 9 is connected to the inside of the deacidification spray pipe 5 through a first connecting pipe 51, ensuring that the flue gas after deacidification can be discharged into the flue gas emission pipe 9 along the first connecting pipe 51 and then discharged into the atmosphere along the flue gas emission pipe 9.

[0030] Furthermore, a slurry diversion hood 64 is fixedly installed at the bottom of the motor mounting box 6. Several second connecting pipes 641 are fixedly installed on the outer wall of the slurry diversion hood 64. The end of the second connecting pipe 641 away from the slurry diversion hood 64 is fixedly connected to and communicates with the matching deacidification spray pipe 5, ensuring that the slurry discharged from the slurry diversion hood 64 can enter the deacidification spray pipe 5. The aforementioned second connecting pipe 641 is located on one side of the rotating blade 63, ensuring that the slurry sprayed from the second connecting pipe 641 can be broken up by the rotating blade 63 and fully atomized.

[0031] Secondly, a cover 61 is fitted onto the top opening of the motor mounting box 6. The cover 61 seals the top opening of the motor mounting box 6, which can protect the servo motor 62 and prevent it from being damaged by rain. A slurry inlet pipe 8 is fixedly installed at the bottom of the motor mounting box 6. The bottom end of the slurry inlet pipe 8 is connected to the inside of the slurry diversion hood 64. The top end of the slurry inlet pipe 8 passes through the opening cut into the cover 61 and extends above it, which makes it convenient to connect the external pipe to the top end of the slurry inlet pipe 8, ensuring that the externally input slurry can be delivered into the slurry diversion hood 64.

[0032] Furthermore, several support plates 41 are fixedly installed on the outer wall of the sealing plate 4, and several second support rods 92 are fixedly installed on the upper surface of the support plates 41. The bottom of the flue gas emission pipe 9 is fixedly connected to the second support rods 92 to ensure that the flue gas emission pipe 9 can be stably erected on one side of the deacidification spray pipe 5. The flue gas emission pipe 9 is fitted with a reinforcing sleeve 91. The reinforcing sleeve 91 is fixed to the outer wall of the motor mounting box 6 through the connecting bracket 93. The reinforcing sleeve 91 limits the flue gas emission pipe 9, which can prevent it from tipping over and strengthen the firmness of the flue gas emission pipe 9 after installation.

[0033] Secondly, a canopy 7 is installed above several flue gas emission pipes 9. The canopy 7 forms a shielding structure above the flue gas emission pipes 9, which can prevent rainwater from dripping into the flue gas emission pipes 9. Several first support rods 71 ​​are fixedly installed on the lower surface of the canopy 7. The bottom end of the first support rods 71 ​​is fixedly connected to the cover 61. The first support rods 71 ​​provide stable support for the canopy 7, which effectively improves the firmness of the canopy 7 after installation.

[0034] In this embodiment, flue gas is first discharged into flue gas collection pipe 2 through flue gas inlet pipe 3. After passing through the circular opening 42 on the sealing plate 4, the flue gas is dispersed into multiple deacidification spray pipes 5, performing zoned deacidification treatment of the flue gas. This reduces the spraying space and allows the flue gas to come into contact with more slurry. As the flue gas enters the deacidification spray pipe 5, an externally installed pressure pump forces the slurry into the slurry discharge pipe 8, ensuring that the slurry can be delivered to the slurry distribution hood 64. Through the second connecting pipe 641, the slurry can be dispersed and sprayed into the deacidification spray pipe 5. Since the open end of the second connecting pipe 641 is located on one side of the rotating blade 63, the servo motor 62 drives the rotation during the process of spraying the slurry into the deacidification spray pipe 5. The high-speed rotation of the blades 63 disperses the sprayed slurry into small droplets, achieving an atomization effect. Once the flue gas comes into contact with the atomized slurry, the deacidification process is complete. The deacidified flue gas is then discharged into the flue gas emission pipe 9 along the first connecting pipe 51, and subsequently discharged into the atmosphere from the opening at the top of the flue gas emission pipe 9. The exhaust pipe in this application is equipped with multiple independent deacidification zones, enabling zoned treatment of the flue gas. The atomization of the slurry using the rotating blades 63 not only achieves the same effect as traditional atomizing discs but also allows the slurry to form smaller droplets, ensuring more thorough contact between the flue gas dispersed in the deacidification spray pipe 5 and the slurry, effectively improving the deacidification effect.

[0035] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
