Technical Field

[0001] The utility model relates to the technical field of ammonia water storage, in particular to a high-strength sealed storage tank. Background Art

[0002] Ammonia water, also known as ammonia water, is an aqueous solution of ammonia. It is colorless, transparent and has a pungent odor. Ammonia gas is easily soluble in water and ethanol. It is volatile and has the general properties of some alkali. Ammonia water is made by passing ammonia gas into water.

[0003] Ammonia storage tanks are used to store ammonia. In the flue gas desulfurization and denitrification process, ammonia is the most important treatment reactant. Since ammonia is easy to volatilize during the storage process, the ammonia gas produced after the ammonia volatilizes can easily cause high pressure in the tank, which can easily cause ammonia leakage. When the ammonia gas in the existing ammonia storage tank leaks, it will directly diffuse into the air and cause environmental pollution, which can easily threaten the safety of the staff and cause safety hazards. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a high-strength sealed storage tank that can solve the problem that when ammonia gas inside the existing ammonia storage tank leaks, it will directly diffuse into the air and cause environmental pollution, which is likely to threaten the safety of the staff and thus cause safety hazards.

[0006] Preferably, a rotating disk for rotation is fixedly sleeved on the surface of the connecting elbow, and rotating rods are welded on the surface of the rotating disk. The rotating rods are equidistantly distributed in a circle around the center of the rotating disk on the surface of the rotating disk.

[0007] Preferably, a disc base is welded on the surface of the ammonia water storage tank, and a groove is formed on the surface of the disc base.

[0008] Preferably, a fixed block is rotatably connected inside the groove, and a positioning hole is provided on the surface of the fixed block.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] See also Figure 1-4 The utility model provides a technical solution: a high-strength sealed storage tank, including an ammonia storage tank 1 and a gas safety treatment mechanism, the interior of the ammonia storage tank 1 is fixedly connected with an inlet and outlet pipe 3, a second storage tank 2 is installed inside the ammonia storage tank 1, and the inlet and outlet pipe 3 is welded on the surface of the second storage tank 2 and communicated with the interior thereof;

[0025] When the high-strength sealed storage tank is in use, the staff discharges and introduces ammonia water into the second storage tank 2 through the inlet and outlet pipes 3 , and then stores the ammonia water in the second storage tank 2 .

[0026] The gas safety handling mechanism includes an intake pipe 4, a connecting elbow 6, a mounting base 7, a gas compressor 8 and an exhaust pipe 9. The intake pipe 4 is placed in the middle of the second storage tank 2 and the ammonia storage tank 1. Air inlets 5 are evenly opened on the surface of the intake pipe 4. The connecting elbow 6 is slidably connected to the middle of the second storage tank 2 and the ammonia storage tank 1 and is fixedly connected to the intake pipe 4. One end of the connecting elbow 6 away from the intake pipe 4 rotates to penetrate the interior of the ammonia storage tank 1 and extends to the outside. The mounting base 7 is welded to the surface of the ammonia storage tank 1. The gas compressor 8 is fixedly mounted on the surface of the mounting base 7. The exhaust pipe 9 is fixedly mounted on the air inlet of the gas compressor 8. One end of the exhaust pipe 9 away from the gas compressor 8 rotates to be connected to the inside of the connecting elbow 6;

[0027] When the ammonia in the second storage tank 2 leaks, the ammonia first diffuses to the middle position between the second storage tank 2 and the ammonia storage tank 1. When the staff finds that the pressure inside the second storage tank 2 has changed, it can be determined that a leak has occurred. At this time, the staff can start the gas compressor 8 and extract the leaked ammonia through the exhaust pipe 9 and the intake pipe 4. The surface of the intake pipe 4 is provided with multiple air inlets 5 to increase the speed of the intake pipe 4 to extract ammonia. After the gas compressor 8 extracts the ammonia, it can be discharged into the interior of the spare ammonia storage tank, thereby preventing the ammonia from directly diffusing into the air to cause environmental pollution, ensuring the safety of the staff and eliminating safety hazards.

[0028] A rotating disk 10 for rotation is fixedly sleeved on the surface of the connecting elbow 6, and a rotating rod 11 is welded on the surface of the rotating disk 10. The rotating rods 11 are distributed equidistantly in a circle around the center of the rotating disk 10. A disc base 12 is welded on the surface of the ammonia storage tank 1, and a groove 13 is provided on the surface of the disc base 12. A fixed block 14 is rotatably connected inside the groove 13, and a positioning hole 15 is provided on the surface of the fixed block 14. The surface of the rotating rod 11 is slidably connected to the inside of the positioning hole 15, and a spring 16 is fixedly connected to the surface of the fixed block 14, and one end of the spring 16 away from the fixed block 14 is fixedly connected to the inner wall of the groove 13.

[0029] During the process of extracting the leaked ammonia by the gas compressor 8, the staff first slides the fixed block 14 to squeeze the spring 16 and release the fixing effect on the rotating rod 11 and the turntable 10. Then, the staff can rotate the turntable 10 through the rotating rod 11. At this time, the rotation of the turntable 10 can drive the connecting elbow 6 and the intake pipe 4 to rotate on the surface of the second storage tank 2, further accelerating the rate of extracting the leaked ammonia by the intake pipe 4. When there is no need to rotate the turntable 10, the spring 16 can push the fixed block 14 to rotate in the opposite direction and drive the positioning card hole 15 to be stuck on the surface of the rotating rod 11, and then fix the rotating rod 11 and the turntable 10 through the fixed block 14, and then fix the connecting elbow 6 and the intake pipe 4 to the inside of the ammonia storage tank 1, so as to prevent the connecting elbow 6 and the intake pipe 4 from rotating freely inside the ammonia storage tank 1.

[0030] Working principle: When the ammonia in the second storage tank 2 leaks, the ammonia first diffuses to the middle position between the second storage tank 2 and the ammonia storage tank 1. The staff can start the gas compressor 8 and extract the leaked ammonia through the exhaust pipe 9 and the intake pipe 4 and discharge it into the spare ammonia storage tank, thereby preventing the ammonia from directly diffusing into the air and causing environmental pollution. The staff first slides the fixed block 14 to squeeze the spring 16 and release the fixing effect on the rotating rod 11 and the rotating disk 10. Then, the staff can rotate the rotating disk 10 through the rotating rod 11. At this time, the rotation of the rotating disk 10 can drive the connecting elbow 6 and the intake pipe 4 to rotate on the surface of the second storage tank 2, further accelerating the rate at which the intake pipe 4 extracts the leaked ammonia. When the rotating disk 10 does not need to be rotated, the spring 16 can push the fixed block 14 to rotate in the opposite direction and drive the positioning card hole 15 to be stuck on the surface of the rotating rod 11, and then the rotating rod 11 and the rotating disk 10 are fixed by the fixed block 14 to prevent the connecting elbow 6 and the intake pipe 4 from rotating freely inside the ammonia storage tank 1.

[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
