[0028] 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.

[0029] like Figures 1 to 6 As shown, this utility model provides a dual-header ammonia supply guarantee system, including:

[0030] Transfer box 1, with an air inlet pipe 2 fixedly sleeved on the inner surface of the outer surface of transfer box 1, and a double female pipe 3 fixedly sleeved on the inner bottom of transfer box 1;

[0031] The adjustment mechanism is located inside the transfer box 1;

[0032] The adjustment mechanism includes a rotating shaft 4, the outer surface of which is movably connected to the inside of the top of the transfer box 1. A retaining ring 25 is fixedly fitted on the outer surface of the rotating shaft 4, and the outer surface of the retaining ring 25 is in contact with the transfer box 1. A screw 5 is fixedly installed at the bottom of the rotating shaft 4. A threaded sleeve 6 is threadedly fitted on the outer surface of the screw 5. A moving block 7 is fixedly fitted on the outer surface of the threaded sleeve 6. A through groove 8 is opened on the moving block 7, and the outer surface of the moving block 7 is movably connected to the inside of the double mother tube 3.

[0033] Since the screw 5 is internally threaded with the threaded sleeve 6, when the rotating shaft 4 drives the screw 5 to rotate, the threaded sleeve 6 will move. At this time, the moving block 7 will move under the drive of the threaded sleeve 6. When the moving block 7 moves downward along the inside of the double mother pipe 3, the double mother pipe 3 will increase the amount of obstruction to the through groove 8, thereby adjusting the amount of ammonia transported.

[0034] Among them, a rocker arm 9 is fixedly installed at the top of the rotating shaft 4, and a handle 10 is movably sleeved on the outer surface of the rocker arm 9.

[0035] When the operator shakes the joystick 9, the rotating shaft 4 will rotate. Due to the design of the handle 10, it is easy for the operator to shake the joystick 9.

[0036] The double mother tube 3 has a vertical groove 11 inside, and a movable block 12 is movably connected inside the vertical groove 11. The movable block 12 is fixedly connected to the outer surface of the moving block 7.

[0037] Due to the design of the vertical groove 11, the movement of the movable block 12 will be limited, so that it can only move up and down, and thus the moving block 7 can only drive the movable block 12 to move up and down.

[0038] The outer surface of the retaining ring 25 is fixedly installed with a second sealing ring 26, and the outer surface of the second sealing ring 26 is movably connected to the interior of the transfer box 1.

[0039] The design of the second sealing ring 26 will increase the sealing between the rotating shaft 4 and the transfer box 1.

[0040] Among them, a connecting pipe 13 is fixedly installed at the bottom end of the double mother pipe 3, and a connecting box 14 is fixedly sleeved at the bottom end of the outer surface of the connecting pipe 13. A connecting block 16 is movably sleeved inside the connecting box 14.

[0041] When the ammonia gas inside the transfer box 1 enters the double mother pipe 3, it will move to the inside of the connecting pipe 13 under the guidance of the double mother pipe 3, and finally enter the inside of the connecting block 16 through the connecting pipe 13. Since the connecting block 16 is movably connected to the inside of the connecting box 14, the connecting block 16 can rotate inside the connecting box 14.

[0042] Among them, an air supply pipe 15 is fixedly installed on the outer surface of the connecting box 14, and the interior of the air supply pipe 15 is connected to the interior of the connecting block 16.

[0043] When the connecting block 16 rotates inside the connecting box 14, the interior of the connecting block 16 will connect with the interior of different gas transmission pipes 15 during the rotation, thereby introducing ammonia into the interior of different gas transmission pipes 15.

[0044] The top of the connecting block 16 is fixedly equipped with a sealing ring 18, and the outer surface of the sealing ring 18 is movably connected to the inside of the connecting pipe 13.

[0045] The design of the sealing ring 18 will enhance the sealing between the connecting block 16 and the connecting pipe 13.

[0046] The bottom end of the connecting block 16 is fixedly installed with a first sealing ring 17 and a ring 19. The outer surface of the first sealing ring 17 is movably connected with the inside of the connecting box 14, and the outer surface of the ring 19 is movably connected with the inside of the bottom end of the connecting box 14.

[0047] The design of the first sealing ring 17 and the annulus 19 will enhance the sealing between the connecting block 16 and the connecting box 14.

[0048] The outer surface of the connecting box 14 is fixedly mounted with a fixing frame 20, the bottom end of the fixing frame 20 is fixedly mounted with a motor 21, and the other end of the output shaft of the motor 21 is fixedly sleeved with a short shaft 22.

[0049] When motor 21 is running, short shaft 22 will rotate.

[0050] Among them, a gear 23 is fixedly sleeved on the top of the outer surface of the short shaft 22, and a gear ring 24 is meshed on the outer surface of the gear 23. The inside of the gear ring 24 is fixedly sleeved on the outer surface of the ring 19.

[0051] When the short shaft 22 rotates, it will drive the gear 23 to rotate. Since the outer surface of the gear 23 meshes with the outer surface of the gear ring 24, when the gear 23 rotates, it will drive the gear ring 24 to rotate. At this time, the gear ring 24 will drive the connecting block 16 to rotate inside the connecting box 14 through the ring 19.

[0052] Working principle and usage process of this utility model:

[0053] The urea solution preparation and storage system is designed for use by the two units in Phase I, with space reserved for Phase II Units 3 and 4. Two urea hydrolyzers are installed in the urea hydrolysis zone. The output of each hydrolyzer is designed to meet 100% of the ammonia demand of the two furnaces in Phase I, i.e., a gaseous ammonia output of 496 kg / h per hydrolysis unit. A total of two units are installed, with one in operation and one on standby during normal operation.

[0054] When the operator needs to adjust the ammonia delivery rate, the operator holds handle 10 and shakes the rocker arm 9. The rocker arm 9 drives the rotating shaft 4 to rotate around the connection point with the transfer box 1. The screw 5 rotates under the drive of the rotating shaft 4. Since the outer surface of the screw 5 is connected to the internal thread of the threaded sleeve 6, the rotation of the screw 5 drives the threaded sleeve 6 to move. The moving block 7 moves under the drive of the threaded sleeve 6. At the same time, the moving block 7 drives the two movable blocks 12 to move along the inside of the two vertical grooves 11. Due to the design of the vertical grooves 11, the movement of the movable blocks 12 is limited, so that they can only move up and down. The moving block 7 drives the two movable blocks 12 to move downward along the two vertical grooves 11. As the moving block 7 moves downward, the amount of obstruction of the through groove 8 by the double mother pipe 3 will continuously increase, thereby reducing the amount of ammonia entering the double mother pipe 3. This realizes the function of adjusting the ammonia delivery rate according to the usage requirements.

[0055] The ammonia gas will then enter the interior of the connecting block 16 through the connecting pipe 13, and subsequently enter the interior of the gas delivery pipe 15 to complete the delivery. Due to the design of the first sealing ring 17, sealing ring 18, and ring 19, the sealing performance between the connecting block 16 and the connecting pipe 13 and the connecting box 14 will be enhanced. When the operator needs to deliver ammonia gas to different gas delivery pipes 15, the operator starts the motor 21. At this time, the short shaft 22 will drive the gear 23 to rotate. Since the outer surface of the gear 23 is meshed with the outer surface of the gear ring 24, when the gear 23 rotates, it will drive the gear ring 24 to rotate. At the same time, the gear ring 24 will drive the connecting block 16 to rotate inside the connecting box 14 through the ring 19. At this time, the interior of the connecting block 16 will be connected to the interior of different gas delivery pipes 15 during rotation, thereby realizing the function of delivering ammonia gas to different gas delivery pipes 15 according to the usage requirements.
