Description

Technical Field

[0001] The utility model relates to the technical field of flue gas deacidification treatment, in particular to a semi-dry deacidification reaction tower. Background Art

[0002] With the rapid development of the economy and society, waste incineration power generation has developed rapidly with its advantages of "harmlessness, reduction, and resource utilization". When burning garbage, the garbage incinerator emits a large amount of flue gas from the exhaust port. The flue gas contains acidic gases, so the flue gas needs to be deacidified. At present, most garbage treatment plants use lime slurry to deacidify the flue gas. The flue gas deacidification process of garbage power plants includes dry method, wet method and semi-dry method. The semi-dry method is widely used in garbage power plants due to its advantages of high purification efficiency, simple process, less equipment, easy treatment of products, no secondary pollution and easy adjustment and control.

[0003] Publication No. CN214552504U discloses a semi-dry deacidification reaction tower, which includes a platform, a tank body fixed on the platform, and a conical tank fixed at the bottom of the tank body. A material pump and a dissolving tank are arranged on the platform, ... a baffle is arranged on the left side of the smoke inlet pipe; the inlet end of the material pump is connected to the dissolving tank, and the outlet end of the material pump extends into the filter tank and is located directly above the filter plate. This semi-dry deacidification reaction tower can improve the deacidification effect and prevent the small holes on the ball head from being blocked by its structure, but there is a defect, that is, the ball head is fixedly arranged on the liquid inlet pipe, so that the ball head cannot be directly removed from the liquid inlet pipe. Disassembly requires opening the upper end cover of the tank body, then releasing the connection between the liquid inlet pipe and the filter tank, and then removing the driven gear arranged on the liquid inlet pipe and a series of other operations. Such operations will greatly increase the workload. Disassembly is for cleaning the inside of the sphere, because some lime slurry will remain in the sphere and will solidify after cooling. The solidification will cause the dripping holes on the sphere to be blocked, thereby affecting the dripping effect and reducing the deacidification effect. It is necessary to clean the lime slurry remaining in the sphere in time. Utility Model Content

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Referring to the accompanying drawings: This semi-dry deacidification reaction tower includes a platform 1, a dissolving tank 2 arranged on the platform 1, a bracket 4 supporting a filtering tank 3, and a tank body 5. The dissolving tank 2 is connected to the filtering tank 3 through a pipeline. A rotary atomizer 6 connected to the filtering tank 3 is arranged on the tank body 5. The liquid inlet pipe 61 of the rotary atomizer 6 extends into the tank body 5 and is provided with a sphere 62. The tube end of the liquid inlet pipe 61 placed in the tank body 5 is provided with a pipe connector 7, and a locking unit 8 is arranged on the outer peripheral surface of the pipe connector 7. A sphere connector 9 is arranged on the outer peripheral surface of the sphere 62. A locking node 10 for limiting the final position of the pipe connector 7 on the sphere connector 9 is arranged on the sphere connector 9. The sphere connector 9 is provided with a first guide channel 91, a second guide channel 92, and a third guide channel 93 for guiding the locking unit 8 to reach the locking node 10 via a first guide direction, a second guide direction, and a third guide direction. A side door 51 is arranged on the outer peripheral surface of the tank body 5. The principle of the utility model is that the dissolving tank 2 is used to prepare lime slurry, and then the lime slurry enters the filtering tank 3 to filter the large-size undissolved lime powder, and enters the sphere 62 of the rotary atomizer 6, so that the lime slurry droplets contact with the acid gas in the flue gas and undergo a neutralization reaction, thereby achieving the purpose of deacidification. At the same time, considering that the lime slurry will solidify after cooling, the solidification will cause the dripping hole on the sphere 62 to be blocked, so it is necessary to clean the inside of the sphere 62, so that the sphere 62 and the liquid inlet pipe 61 are set to be disassembled. Connection, that is, through the first guide channel 91 and the second guide channel 92, The guide channel 92, the third guide channel 93, and the locking node 10 define the installation position of the locking unit 8, and can realize the tool-free and parts-free operation mode of assembling the ball connector 9 and the tube connector 7, which can be assembled and connected in the first guide direction, the second guide direction, and the third guide direction, which is suitable for rapid assembly and convenient assembly, and after the locking unit 8 reaches the locking node 10, it can be suspended on the liquid inlet pipe 61 by the gravity of the ball 62, thereby ensuring the installation firmness of the ball 62 and preventing the locking unit 8 from being separated from the locking node 10. In this embodiment, the locking node 10 is set as a semicircular structure, and the locking unit 8 is set as a cylindrical structure matching the inner diameter of the semicircular structure.

[0020] The spherical connector 9 is provided with a first turning channel 94 which guides the locking unit 8 from the first guide channel 91 to the second guide channel 92 via the first turning guide direction. When the locking unit 8 slides in the first turning channel 94, the corresponding first turning guide direction is an arc-shaped direction and can be clearly felt by the user, which will play a corresponding prompting role, so that the user can predict that the locking unit 8 has reached the first turning channel 94, thereby avoiding user misjudgment.

[0021] The first turning channel 94 is formed with a first fitting wall 94-a which is completely fitted on a partial surface of the locking unit 8 when the locking unit 8 reaches the first turning channel 94, so that the locking unit 8 is accurately positioned in the first turning channel 94 to match the accuracy of the locking unit 8 entering the second guide channel 92.

[0022] The spherical connector 9 is provided with a second turning channel 95 which guides the locking unit 8 from the second guide channel 92 to the third guide channel 93 via the second turning guide direction. The purpose of the second turning channel 95 is consistent with that of the first turning channel 95. When the locking unit 8 slides in the second turning channel 95, the corresponding second turning guide direction is an arc-shaped direction and can be clearly felt by the user, which will play a corresponding prompting role, so that the user can predict that the locking unit 8 has reached the second turning channel 95, thereby avoiding user misjudgment.

[0023] The second turning channel 95 is formed with a second fitting wall 95-a which is completely fitted on a partial surface of the locking unit 8 when the locking unit 8 reaches the second turning channel 95, so that the locking unit 8 is accurately positioned in the second turning channel 95 to match the accuracy of the locking unit 8 entering the third guide channel 93.

[0024] There are two locking nodes 10 which are symmetrically distributed, and allow the locking units 8 to enter or disengage simultaneously when the sphere 62 rotates counterclockwise or clockwise. The curbs formed by the first guide channel 91, the first turning channel 94, the second guide channel 92, the second turning channel 95, and the third guide channel 93 match the number of locking nodes 10. The two settings enable the tube connector 7 to maintain good connection stability after being connected to the spherical connector 9, that is, the sphere 62 will not deviate to the side, so that the dripping rate is stable and uniform, so that each dripping hole can drip.

[0025] The sphere 62 includes a first hemisphere 62-a and a second hemisphere 62-b. The lower surface of the first hemisphere 62-a is provided with a threaded extension section 62-a1, and the upper surface of the second hemisphere 62-b is provided with a threaded groove 62-b1 for the threaded extension section 62-a1 to be placed inside and spliced ​​with the first hemisphere 62-a. Such a configuration allows the sphere 62 to be disassembled, that is, it can be rotated by means of threaded connection between the threaded groove 62-b1 and the threaded extension section 62-a1. The disassembly allows the sphere 62 to be fully cleaned, so that the inner cavity parts of the first hemisphere 62-a and the second hemisphere 62-b can be exposed, thereby achieving a good cleaning effect.
