[0002] Existing denitrification technologies include SNCR, SCR, and integrated denitrification. For gas-fired boilers, SNCR and SCR processes are unsuitable, while integrated denitrification is appropriate. Integrated denitrification refers to solid-state polymer denitrification technology that does not use catalysts. The solid polymer reducing agent is injected into the boiler or flue through pipes and spray guns, sublimates, and then reacts with NO. X The denitrification process involves a reduction reaction to achieve the emission targets.
[0003] During the operation of an integrated denitrification system, the blower frequently clogs the pipes while transporting the reagents, as the reagents are solid particles and are easily affected by moisture. Additionally, the interfaces between the pipes and spray guns are also prone to clogging due to variations in pipe diameter, making cleaning difficult. Therefore, this invention provides a pipe unclogging device for integrated denitrification systems to solve the clogging problems at the pipes and spray guns. Utility Model Content

[0019] Beneficial effects:
[0020] (1) The pipe unblocking device for the integrated denitrification system is equipped with a compressed air unblocking component and a circulating water unblocking component on the conveying pipe. When the external system shows that the pipe is blocked, compressed air is used to purge the pipe. When compressed air cannot clear the blockage, circulating water is used to clear the blockage.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0031] Example 1
[0032] Please see Figures 1 to 4 As shown, this utility model provides a pipe unclogging device for an integrated denitrification system, including a Roots blower 1, a reagent tank 2, and a spray gun 3. The reagent tank 2 stores solid reagents, and the conveying pipe 4 is L-shaped with a large elevation difference. It also includes:
[0033] The material conveying pipeline 4 is composed of multiple steel pipes 401, and each pair of steel pipes 401 are connected by a locking mechanism.
[0034] A compressed air unblocking component is installed on the surface of the conveying pipeline 4 and is used to purge the pipeline with compressed air. The compressed air unblocking component includes a first branch pipe 7 and a second branch pipe 8 connected to the surface of the conveying pipeline 4. Both the first branch pipe 7 and the second branch pipe 8 are equipped with valves. One end of the first branch pipe 7 and the second branch pipe 8 is flanged and connected to a compressed air pipeline network 9. The compressed air pipeline network 9 is a compressed air pipeline in the plant area pipeline network. The first branch pipe 7 and the second branch pipe 8 are located in the vertical section and the horizontal section of the conveying pipeline 4, respectively, which improves the unblocking effect of compressed air when there is a large height difference in the agent conveying pipeline.
[0035] A circulating water unblocking component is installed at the top of the conveying pipe 4 and is used to unblock the blockage with circulating water. The circulating water unblocking component includes an inlet pipe 10, the bottom end of which is connected to the top flange of the conveying pipe 4. The other end of the conveying pipe 4 is connected to an outlet pipe 11, forming a circulating water system with the external water supply network. When compressed air cannot unblock the blockage, circulating water can be used to unblock the blockage. Valves are installed inside both the inlet pipe 10 and the outlet pipe 11.
[0036] The quick-connect sight glass type spray gun interface 5 is located between the spray gun 3 and the material conveying pipe 4. Part of this interface is transparent, allowing for a more direct observation of the unblocking situation.
[0037] The drying unit 6 is located on one side of the conveying pipe 4 and is used to heat and dry the conveying pipe 4.
[0038] The outlet of the Roots blower 1 is connected to the feed cylinder 12, and the top of the feed cylinder 12 is connected to the bottom of the reagent chamber 2. One side of the feed cylinder 12 is connected to one end of the conveying pipe 4 via a pipe flange. The two ends of the quick-connect sight glass type spray gun interface 5 are connected by clamps, which makes disassembly and assembly convenient and reduces maintenance time.
[0039] With the above structure, when the external system indicates that the pipeline is blocked, compressed air is used to purge the pipeline. When compressed air cannot clear the blockage, circulating water is used. At the same time, a quick-connect sight glass type spray gun interface 5 is provided at the interface between the material conveying pipeline 4 and the spray gun 3 using a clamp-type connection, which facilitates more intuitive observation of the blockage clearing situation and is easy to disassemble and assemble. The above-mentioned blockage clearing device is adaptable to different blockage situations, improves the efficiency of blockage clearing, and reduces the impact on production.
[0040] Example 2
[0041] Based on Example 1, please refer to Figure 1 , Figure 3 and Figure 4 As shown, the specific improvements are as follows: The drying mechanism 6 includes a hot air blower 61, which can adjust the temperature and wind speed. The air inlet of the hot air blower 61 is connected to a filter 62 through a pipe. The filter 62 filters dust and impurities in the air, making the drying gas cleaner. The air outlet of the hot air blower 61 is connected to a first air inlet pipe 63, and the bottom of the first air inlet pipe 63 is connected to a second air inlet pipe 64. The first air inlet pipe 63 and the second air inlet pipe 64 are respectively connected to the top and bottom of the conveying pipe 4, making the hot air distribution more uniform and improving the drying efficiency of the pipe. Both the vertical and horizontal sections of the conveying pipe 4 are equipped with air outlet pipes 65. The first air inlet pipe 63, the second air inlet pipe 64 and the air outlet pipe 65 are all equipped with solenoid valves, which are controlled by an external switch. The inner wall of the air outlet pipe 65 is fixedly connected with a dustproof net 66. When the air is circulating, the dustproof net 66 prevents external dust and other objects from entering the conveying pipe 4 through the air outlet pipe 65.
[0042] The material conveying pipe 4 includes a base layer 41, a heat insulation layer 42 sprayed on the inner wall of the base layer 41, and a nano coating 43 sprayed on the inner wall of the heat insulation layer 42. The heat insulation layer 42 is a ceramic spraying material, which can play a role in preventing scalding when heating the pipe. The nano coating 43 is hydrophobic, which can significantly reduce moisture adhesion and retention, reduce moisture accumulation, and help improve the efficiency of the drying process.
[0043] With the above structure, after the circulating water unblocking component unblocks the conveying pipe 4, the drying mechanism 6 can deliver hot air to the inside of the conveying pipe 4, quickly evaporate the moisture and carry it away through the airflow, accelerate the drying speed of the pipe and improve the efficiency of denitrification production.
[0044] Example 3
[0045] Please refer to Embodiment 1 and Embodiment 2 for details. Figure 1 , Figure 5 and Figure 6 As shown, the specific improvements are as follows: The locking mechanism includes flanges 13 at both ends of the steel pipe 401. A sealing ring is provided at the connection of the two flanges 13 to improve the sealing performance. An annular sleeve plate 14 is fixedly connected to both sides of the surface of one flange 13. A fixing rod 15 is threaded through the surface of the other flange 13. The bottom of the surface of the fixing rod 15 is threaded and can be connected to the threaded hole on the surface of the flange 13 to improve the connection stability of the locking mechanism. Springs 16 are fixedly connected to both sides of the inner wall of the annular sleeve plate 14. An arc plate 17 is fixedly connected to one end of the spring 16. A locking block 18 is fixedly connected to the inner side of the arc plate 17. Limiting plates 19 are fixedly connected to both the front and rear sides of the inner wall of the annular sleeve plate 14 to limit the fixing rod 15. A slot 20 that matches the locking block 18 is opened on the surface of the fixing rod 15. A handle 21 is fixedly connected to the top of the arc plate 17 to facilitate the movement of the locking block 18.
[0046] With the above structure, the multiple steel pipes 401 are connected by a locking mechanism, which is simple and quick to operate without the need for external tools. When a certain part of the conveying pipe 4 is damaged or blocked too severely, the pipe at that point can be disassembled, cleaned or replaced more conveniently.
[0047] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment compatible with the device can be used.
[0048] During use, the agent is sprayed into the furnace through the conveying pipe 4 and the spray gun 3 by the Roots blower 1. When the conveying pipe 4 is blocked, the valves of the first branch pipe 7 and the second branch pipe 8 are manually opened. The compressed air network 9 delivers compressed air to the conveying pipe 4 and blows the pipe to clear the blockage. When the compressed air cannot clear the blockage, the valves of the inlet pipe 10 and the outlet pipe 11 are manually opened. The circulating water network delivers water to the conveying pipe 4 and clears the blockage with circulating water. After clearing the blockage with circulating water, the hot air blower 61 is started to deliver hot air to the conveying pipe 4 through the first air inlet pipe 63 and the second air inlet pipe 64. At the same time, the valve of the outlet pipe 65 is opened to quickly evaporate the moisture and carry it away with the airflow, thus accelerating the drying speed of the pipe.
[0049] The conveying pipe 4 is composed of multiple steel pipe sections 401. When assembling the steel pipes 401, pull the handle 21 inside the annular sleeve 14 to drive the arc plate 17 to squeeze the spring 16, moving the locking block 18 to both sides. This allows the fixing rod 15 on one steel pipe section 401 to pass through the two flanges 13 and the annular sleeve 14 on the other steel pipe section 401 in sequence. Then, release the handle 21. Under the reaction force of the spring 16, the locking block 18 enters the locking groove 20 of the fixing rod 15, thereby locking the flanges 13 on the two steel pipe sections 401 together. This process is repeated to complete the assembly of the conveying pipe 4. Conversely, by moving the locking block 18 out of the locking groove 20 and pulling out the two flanges 13 with the fixing rod 15, the two steel pipe sections 401 can be disassembled. When a certain part of the conveying pipe 4 is damaged or severely blocked, the pipe at that point can be disassembled separately for easy cleaning or replacement.
[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
