Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Example 1. This example aims to facilitate the solution of the problem in the prior art that for the denitration treatment of the furnace body 110, most use chemicals for treatment, but during the treatment process, due to poor sealing effect, gas leakage may occur, thus increasing the risk of air pollution. Please refer to Figures 1-6 , a denitration device for a steam superheater, including a furnace body 110. A treatment tank 160 is provided in the middle of the furnace body 110. A heat dissipation pipe 120 is inserted in the middle of the treatment tank 160. A discharge pipe 150 is inserted on the side of the furnace body 110. A connecting pipe 130 is threadedly connected to the end of the furnace body 110. A clamping pipe 140 is fixedly connected to the side of the connecting pipe 130. A sealing assembly 240 is provided in the middle of the clamping pipe 140. An insertion column 170 is inserted in the middle of the clamping pipe 140.

[0025] An insertion cylinder 180 is provided in the middle of the insertion column 170. A compression spring 200 is fixedly connected to the side of the insertion cylinder 180. Clamping grooves 190 are provided on both sides of the insertion column 170. The clamping pipe 140 includes a connecting ring 210 installed on the side of the connecting pipe 130. A return spring 220 is fixedly connected to the side of the connecting ring 210. The return spring 220 is sleeved on the side of the clamping cylinder 230.

[0026] When denitration treatment is required inside the furnace body 110, the insertion column 170 is connected to the medicine pipe, and then the insertion column 170 is clamped and connected to the clamping pipe 140. During the clamping process, the insertion cylinder 180 in the insertion column 170 will squeeze the sealing plate 390 in the sealing assembly 240. When the sealing pipe is stressed, through the hinge of the rotating plate 380 and the fixed rod 360, the rotating plate 380 and the sealing plate 390 will be stressed and opened. When the sealing plate 390 is opened, the torsion spring 370 will be stressed and contracted. Then when the insertion column 170 is removed, the torsion spring 370 will be unrestricted by force and reset. At this time, the sealing treatment can be carried out again.

[0027] In this example: By providing a treatment tank 160 and a heat dissipation pipe 120 in the middle of the furnace body 110, the denitration treatment of flue gas can be effectively carried out, reducing the emission of nitrogen oxides. Through the setting of the sealing assembly 240 in the middle of the clamping pipe 140, the overall stability of the device is ensured, and the risk of leakage is reduced. Through the setting of the insertion column 170 and the opening of the clamping grooves 190, the relevant components can be conveniently maintained and replaced, reducing the maintenance cost. Through the setting of the sealing assembly 240, including the cooperation of structures such as a fixed frame 330, a connecting spring 350, a torsion spring 370 and a sector plate, good sealing performance is provided, preventing flue gas leakage and ensuring the denitration efficiency. The design of the clamping pipe 140 and the connecting ring 210, as well as the application of the return spring 220, enable the connecting pipe 130 to be flexibly connected and disconnected, facilitating operation.

[0028] Example 2. This example aims to facilitate the solution of the problem of inconvenient operation during the operation process. This example is an improvement based on Example 1. Specifically, please refer to Figures 1-6 , the side of the clamping cylinder 230 is connected to the sealing assembly 240.

[0029] A ball 260 is installed on the side of the collar 270. The side of the collar 270 is fixedly connected with a sleeve 280. A clamping bead 290 is installed on the side of the sleeve 280. A limiting groove 310 is formed in the middle of the clamping pipe 140. A limiting spring 320 is arranged in the middle of the limiting groove 310. A moving sleeve 300 is fixedly connected to the side of the limiting spring 320.

[0030] The sealing assembly 240 includes a fixed frame 330 installed in the middle of the contact cylinder 250. An installation groove 340 is formed in the middle of the fixed frame 330. A connecting spring 350 is arranged in the middle of the installation groove 340. The side of the connecting spring 350 is sleeved on the side of the fixed rod 360. The side of the fixed rod 360 is hinged to the middle of the rotating plate 380. A torsion spring 370 is installed on the side of the fixed rod 360.

[0031] In this example: Through the settings of the collar 270, the ball 260, the sleeve 280 and the clamping bead 290, the service life of the device can be improved. Through the settings of the limiting groove 310 and the limiting spring 320, and the application of the moving sleeve 300, the limiting and shock-proof functions are provided, protecting the internal components from damage. Through the setting of the extrusion spring 200, the position of the insertion post 170 can be adjusted to ensure the tight fit of the sealing assembly 240 and improve the sealing effect. Through the setting of the heat dissipation pipe 120, it helps to uniformly cool the flue gas, improves the heat exchange efficiency, reduces the energy consumption, and reduces the emission of nitrogen oxides through effective denitrification treatment.
