Therefore, the high-temperature flue gas is highly destructive to the environment. The flue gas cannot be directly discharged into the environment. Therefore, the treatment system for desulfurization and denitrification of flue gas has been widely used in real life.

A transfer pipeline 11 is connected between two adjacent connecting interfaces 10, and a valve is also arranged on the transfer pipeline 11. When it is necessary to keep two flue gas conveying pipelines 3 perpendicular to each other with the driving rotating shaft 12 as the center point connected, after the valve on the connecting interface 10 is opened in the flue gas conveying pipeline 3 with higher pressure, the flue gas will pass through the fixed cylinder 14 and enter the connecting interface 10 on the other side, but the connecting interface 10 on the other side remains closed, so that the flue gas will not enter the corresponding flue gas conveying pipeline 3. At this time, the valve on the corresponding transfer pipeline 11 is opened again to allow the flue gas to enter the corresponding connecting interface 10, and the flue gas is allowed to enter the corresponding flue gas conveying pipeline 3 for transportation together, so as to adjust the flue gas conveying pressure in the high-pressure flue gas conveying pipeline 3 and compensate for the flue gas conveying speed in the flue gas conveying pipeline 3 with lower pressure.

[0025] Each smoke delivery pipeline 3 is provided with a partition delivery assembly 200, which includes a partition cylinder 19, a partition cylinder 19 is fixedly connected in the smoke delivery pipeline 3, a partition plate 20 is fixedly connected to the middle of the partition cylinder 19, and the partition plate 20 divides the partition cylinder 19 into two gas delivery chambers, and the upper and lower sides of the gas delivery chamber are connected with gas delivery interfaces 21, and valves are also provided on the gas delivery interfaces 21, and one of the gas delivery chambers is connected with a delivery interface 31. In order to deliver high-temperature smoke to the installation cylinder 5 for cooling, after opening the valve of the gas delivery interface 21 on the lower side, the high-temperature smoke enters the two gas delivery chambers, and then the valve of the gas delivery interface 21 on the top of the gas delivery chamber connected to the delivery interface 31 is closed, so that the high-temperature smoke enters the installation cylinder 5 through the delivery interface 31; The installation cylinder 5 is connected with a plurality of partition conveying components 200, a smoke cooling mechanism 300 is arranged in the installation cylinder 5, the smoke cooling mechanism 300 is connected with the smoke balancing cylinder 2, a reflux pipe 6 is arranged between the smoke cooling mechanism 300 and the smoke conveying pipe 3, the smoke cooling mechanism 300 comprises an annular support frame 22, a heat sink 24, a heat sink fin 25, a water supply component, a conveying flue 26 and a drain pipe 27, an annular support frame 22 is fixedly connected in the installation cylinder 5, a flexible expansion cylinder 23 is arranged in the annular support frame 22, the flexible expansion cylinder 23 is connected with the conveying interface 31, a plurality of grooves are arranged at the bottom of the flexible expansion cylinder 23, a heat sink 24 is fixedly connected between the groove and the installation cylinder 5, a plurality of heat sink fins 25 are fixedly connected on the inner top wall of the installation cylinder 5, a sloped slide groove is provided in the heat sink fin 25, a water supply is arranged at the top of the installation cylinder 5 The top of the flexible expansion cylinder 23 is connected to the smoke distribution cylinder 2 with a conveying flue 26, the return pipe 6 is connected to the conveying flue 26, and a valve is also provided on the return pipe 6. The bottom of the installation cylinder 5 is connected to a drain pipe 27, and the drain pipe 27 runs through the fixed support cylinder 1. When the high-temperature flue gas needs to be cooled, the high-temperature flue gas is first transported to the flexible expansion cylinder 23. After a sufficient amount of flue gas enters the flexible expansion cylinder 23, the flexible expansion cylinder 23 will expand, and the outer wall of the flexible expansion cylinder 23 will contact the heat sink 24 and the heat sink fins 25, and the heat of the high-temperature flue gas will be transferred to the heat sink 24 and the heat sink fins 25. Because after the flexible expansion cylinder 23 is inflated and expanded, the heat sink 24 and the heat sink fins 25 will sink into the flexible expansion cylinder 23, so as to facilitate the heat transfer of the high-temperature flue gas inside the flexible expansion cylinder 23. The cooled flue gas is transported to the smoke equalizing tube body 2 through the conveying flue 26, and by opening the valve on the corresponding return pipe 6, the cooled flue gas is transported to the corresponding flue gas conveying pipe 3 through the return pipe 6, in order to replenish the flue gas in the smoke conveying pipe 3 or balance the smoke temperature in the smoke conveying pipe 3.

[0026] Water is supplied to the installation cylinder 5 through the water supply assembly, so that the water flows downward along the sloped groove in the heat dissipation fins 25, thereby improving the heat dissipation effect of the heat dissipation fins 25, and the heat dissipation fins 24 are immersed in the cooling water, so that the heat dissipation fins 24 can fully dissipate the high temperature in the flexible expansion cylinder 23, and after the cooling water in the installation cylinder 5 is heated, it is discharged through the drain pipe 27.

[0027] The water supply assembly includes an annular water supply cylinder 28 and a drain head 30. The annular water supply cylinder 28 is arranged at the top of the installation cylinder body 5. A water inlet pipe 29 is communicated with the annular water supply cylinder 28. A plurality of drain heads 30 are communicated with the bottom of the annular water supply cylinder 28. The drain heads 30 correspond to the heat dissipation fins 25 one by one. Water is injected into the annular water supply cylinder 28 through the water inlet pipe 29, so that the cooling water is discharged through the plurality of drain heads 30 to inject water onto the upper side of the heat dissipation fins 25 in the installation cylinder body 5, so that the cooling water cools the flue gas in the flexible expansion cylinder body 23.

[0028] The working principle of the flue gas equalizing device for desulfurization and denitrification: First, the flue gas discharged from multiple devices is respectively transported to the corresponding flue gas transport pipelines 3, and then the flue gas is transported upward in the flue gas transport pipelines 3. Then, the driving motor 13 is started to drive the driving rotating shaft 12 to rotate, so that the rotating cylinder body 9 adjusts its position along the center point of the driving rotating shaft 12. After one of the movable insertion cylinders 15 corresponds to the flue gas transport pipeline 3 with a larger pressure, then the double-headed electric cylinder 17 is started to drive the two movable insertion cylinders 15 to move in the rotating cylinder body 9, so that one side of the movable insertion cylinder 15 enters into the communication interface 10, and the sealing ring sleeve 18 is closely attached to the inner wall of the communication interface 10, so that the two corresponding communication interfaces 10 are kept in communication. After the valve on the communication interface 10 of the flue gas transport pipeline 3 with a larger pressure is opened, the flue gas will pass through the fixed cylinder body 14 and enter into the communication interface 10 on the other side, but the communication interface 10 on the other side remains closed, so that the flue gas will not enter into the corresponding flue gas transport pipeline 3. At this time, the valve on the corresponding transfer pipeline 11 is opened again, so that the flue gas enters into the corresponding communication interface 10 and enters into the corresponding flue gas transport pipeline 3 for joint transportation; In order to convey high-temperature flue gas into the installation cylinder body 5 for cooling, after opening the valve of the gas transmission interface 21 on the lower side, the high-temperature flue gas enters into the two gas transmission chambers, and then the valve of the gas transmission interface 21 at the top of the gas transmission chamber connected to the transmission interface 31 is closed, so that the high-temperature flue gas enters into the flexible expansion cylinder body 23 through the transmission interface 31. After a sufficient amount of flue gas enters into the flexible expansion cylinder body 23, the flexible expansion cylinder body 23 will expand, and the outer wall of the flexible expansion cylinder body 23 will contact the heat sink 24 and the heat dissipation fins 25, transferring the heat of the high-temperature flue gas to the heat sink 24 and the heat dissipation fins 25. Because after the flexible expansion cylinder body 23 is inflated and expanded, both the heat sink 24 and the heat dissipation fins 25 will sink into the flexible expansion cylinder body 23, which is convenient for transferring the heat of the high-temperature flue gas inside the flexible expansion cylinder body 23. Water is injected into the annular water supply cylinder 28 through the water supply pipe 29, so that the cooling water is discharged through a plurality of drainage heads 30 to inject water onto the upper side of the heat dissipation fins 25 in the installation cylinder body 5, so that the cooling water cools the flue gas in the flexible expansion cylinder body 23. The cooled flue gas is then conveyed to the smoke equalizing cylinder body 2 through the conveying flue 26. By opening the valve on the corresponding return pipe 6, the cooled flue gas is conveyed to the corresponding flue gas conveying pipe 3 through the return pipe 6 to supplement the flue gas in the flue gas conveying pipe 3 or balance the temperature of the flue gas in the flue gas conveying pipe 3.

[0029] Embodiment 2, based on a smoke equalizing device for desulfurization and denitrification, the present invention also proposes a smoke equalizing method for desulfurization and denitrification, which specifically includes the following steps: Step 1, conveying flue gas: Convey the flue gas discharged from multiple devices into the corresponding flue gas conveying pipes 3 respectively, and then make the flue gas convey upward in the flue gas conveying pipes 3.

[0030] Step 2, transferring flue gas: Start the driving motor 13 to drive the driving rotating shaft 12 to rotate, so that the rotating cylinder body 9 rotates along the center point of the driving rotating shaft 12. Align one of the movable inserting cylinders 15 with the high-pressure flue gas conveying pipe 3. Start the double-headed electric cylinder 17 to drive the two movable inserting cylinders 15 to move in the rotating cylinder body 9, so that one side of the movable inserting cylinder 15 enters into the communication interface 10, and the sealing ring sleeve 18 is closely attached to the inner wall of the communication interface 10, so that the communication between the two corresponding communication interfaces 10 is maintained. After the valve on the communication interface 10 of the flue gas conveying pipe 3 with higher pressure is opened, the flue gas will pass through the fixed cylinder body 14 and enter into the communication interface 10 on the other side, but the communication interface 10 on the other side remains closed, so that the flue gas will not enter into the corresponding flue gas conveying pipe 3. At this time, open the valve on the corresponding transfer pipeline 11, so that the flue gas enters into the corresponding communication interface 10 and enters into the corresponding flue gas conveying pipe 3 for conveying together.

[0031] Step 3, cooling the flue gas: open the valve of the gas delivery interface 21 at the lower side to allow the high-temperature flue gas to enter the two gas delivery chambers, and then close the valve of the gas delivery interface 21 at the top of the gas delivery chamber connected to the delivery interface 31, so that the high-temperature flue gas enters the flexible expansion cylinder 23 through the delivery interface 31. After the high-temperature flue gas enters the flexible expansion cylinder 23, the flexible expansion cylinder 23 will expand, and the outer wall of the flexible expansion cylinder 23 will contact the heat sink 24 and the heat sink fins 25, so as to transfer the heat of the high-temperature flue gas to the heat sink 24 and the heat sink fins 25; Step 4: water injection: water is injected into the annular water supply cylinder 28 through the water supply pipe 29, and the cooling water is discharged through multiple drainage heads 30 to inject water into the upper side of the heat dissipation fins 25 in the installation cylinder 5, so that the cooling water cools the flue gas in the flexible expansion cylinder 23; Step 5, flue gas reflux: the cooled flue gas is transported to the flue gas 2 through the transport flue 26, and the valve on the corresponding reflux pipe 6 is opened to transport the cooled flue gas to the corresponding flue gas transport pipe 3 through the reflux pipe 6, so as to replenish the flue gas in the flue gas transport pipe 3 or balance the flue gas temperature in the flue gas transport pipe 3; Step 6, smoke distribution: finally, the smoke in the smoke conveying duct 26 and the multiple smoke conveying pipes 3 is maintained at a similar flow rate to enter the smoke distribution cylinder 2, and finally discharged through the multiple smoke exhaust holes on the smoke distribution cylinder 2.
