Description

Technical Field

[0001] The utility model relates to the technical field of denitration technology, in particular to an ammonia absorption device in a denitration ammonia tank area. Background Art

[0002] The denitrification process is the removal of nitrogen oxides contained in the flue gas. In the denitrification process, the denitrification reducing agent (commonly used are ammonia water, liquid ammonia, urea, etc.) selectively reacts with NOx in the flue gas to generate nitrogen and water, thereby removing NOx from the flue gas. The injection and mixing of the denitrification reducing agent are important components of the entire system. The existing ammonia injection system is usually ejected from the ammonia water storage tank, gasified by the evaporator (or other evaporation device), and then mixed with the high-temperature flue gas through the injection grid arranged on the inlet flue to enter the denitrification reaction, such as the application number 202021286629.4.

[0003] Generally, ammonia is supplied to an ammonia storage tank via an ammonia truck. However, as the ammonia truck gradually fills the tank, it opens to allow gas inside to escape, allowing ammonia to continue flowing into the tank. However, the gas discharged from the ammonia storage tank contains ammonia gas, causing ammonia to escape into the air. Therefore, the applicant has developed a new technical solution during actual production to address the aforementioned technical issues. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] A denitrification ammonia tank area ammonia absorption device, such as Figure 1 and Figure 2, including an ammonia water storage tank 1, an ammonia water cart 2, two fixed pipes 3 with valves arranged on the ammonia water cart 2, and two hoses 4 connected to the upper side of the outer wall of the ammonia water storage tank 1, and the two hoses 4 are connected to the two fixed pipes 3 through connectors at one end away from the ammonia water storage tank 1. The two fixed pipes 3 are opposite to each other up and down, and a liquid pump 5 is provided on the fixed pipe 3 located at the bottom, and an L-shaped conduit 21 located inside the ammonia water cart 2 is provided on the fixed pipe 3 located at the bottom, and the pipe opening of the conduit 21 at one end away from the fixed pipe 3 is located at the bottom inside the ammonia water cart 2.

[0022] like Figure 1 and Figure 2 , connect the two mounting pipes 6 to the two fixed pipes 3 respectively through connecting pieces, then open the valves on the two fixed pipes 3, and then turn on the liquid extraction pump 5. At this time, the ammonia water in the ammonia water cart 2 will pass through the conduit 21, the fixed pipe 3 located below, one of the mounting pipes 6, and the hose 4 in sequence into the ammonia water storage tank 1. When the ammonia water enters the ammonia water storage tank 1, the gas in the ammonia water storage tank 1 will enter the ammonia water cart 2 in sequence from the other hose 4, the mounting pipe 6 and the fixed pipe 3 located above. At this time, while ammonia water is input into the ammonia water storage tank 1 through the ammonia water cart 2, the gas discharged from the ammonia water storage tank 1 is collected to reduce the occurrence of ammonia escaping into the air. It is simple and convenient to use.

[0023] like Figure 2 and Figure 3 The connecting parts include mounting pipes 6 that are connected to the ends of the two hoses 4 away from the ammonia storage tank 1, and both mounting pipes 6 are provided with stop valves 7. The ammonia cart 2 is provided with a horizontal fixed plate 8 at one end close to the two fixed pipes 3, and the fixed plate 8 is located below the fixed pipe 3. The two fixed plates 8 are horizontally slidably connected with a slide plate 9 through a moving part. The two slide plates 9 are provided with a clamping part for clamping the mounting pipe 6. When the mounting pipe 6 is clamped on the slide plate 9 through the clamping part, the mounting pipe 6 is aligned with the fixed pipe 3, and a rubber sealing layer 10 is installed on the side of the fixed pipe 3 close to the mounting pipe 6.

[0024] like Figure 2 and Figure 3 When the mounting tube 6 needs to be installed on the fixed tube 3, it is only necessary to clamp the mounting tube 6 on the slide plate 9 through the clamping piece. At this time, the mounting tube 6 is aligned with the fixed tube 3, and then the slide plate 9 is driven close to the fixed tube 3 by the moving piece. At this time, the mounting tube 6 will follow the slide plate 9 to move until the mounting tube 6 and the rubber sealing layer 10 on the fixed tube 3 are tightly pressed. At this time, the mounting tube 6 can be connected to the fixed tube 3. The connection between the mounting tube 6 and the fixed tube 3 is simple and quick. After the ammonia water input is completed, close the stop valves 7 on the two mounting tubes 6, and then disconnect and remove the mounting tube 6 from the fixed tube 3. It is easy to use.

[0025] like Figure 2 and Figure 3When the mounting tube 6 is clamped on the slide 9, the clamping member 12 is provided with a rectangular groove 12 above one side of the slide 9, and the rectangular groove 12 is communicated with the top of the slide 9. The top of the slide 9 is hinged with a closing plate 13 for closing the top notch of the rectangular groove 12. The outer wall of the mounting tube 6 is coaxially fixedly connected with a clamping ring 14. The mounting tube 6 is provided with a clamping ring 14. One end of the clamping ring 14 passes through the rectangular groove 12, and the clamping ring 14 is close to the side of the hose 4 and contacts the slide 9. The purpose of this arrangement is that when it is necessary to clamp the mounting tube 6 on the slide 9, it is only necessary to put the mounting tube 6 into the rectangular groove 12 from top to bottom, and make the clamping ring 14 on the mounting tube 6 close to the side of the hose 4 contact with the slide 9. At this time, the mounting tube 6 is aligned with the fixed tube 3, and then the closing plate 13 is rotated so that the closing plate 13 closes the top notch of the rectangular groove 12. At this time, the mounting tube 6 can be clamped on the slide 9. When the mounting tube 6 and the rubber sealing layer 10 on the fixed tube 3 are pressed tightly, the clamping ring 14 will press tightly against the slide 9, which is simple and convenient to use.

[0026] like Figure 2 and Figure 3 A fixing ring 15 is coaxially fixedly connected to the outer wall of the fixed tube 3, and the side of the fixing ring 15 close to the mounting tube 6 is flush with the pipe mouth of the fixing tube 3, and the side of the clamping ring 14 close to the fixing tube 3 is flush with the pipe mouth of the mounting tube 6. At this time, the rubber sealing layer 10 can be detachably installed on the side of the fixing ring 15 close to the clamping ring 14. The purpose of this setting is that the mounting ring and the rubber sealing layer 10 on the fixing ring 15 are tightly pressed. When the mounting ring and the rubber sealing layer 10 on the fixing ring 15 are tightly pressed, the side of the clamping ring 14 away from the slide 9 will be tightly pressed against the rubber sealing layer 10. At this time, through the cooperation of the clamping ring 14 and the rubber sealing layer 10, the sealing effect between the mounting tube 6 and the fixed tube 3 can be improved, and it is simple and convenient to use.

[0027] like Figure 2 and Figure 3 The moving part includes two slides 16 arranged at the top of the fixed plate 8, and the two slides 16 are arranged along the length direction of the fixed tube 3 and are respectively located on both sides of the fixed tube 3. The slide plate 9 is horizontally slidably connected between the two slides 16. Two opposite baffles 17 are provided at the top of the fixed plate 8, and a screw rod 18 is rotatably connected between the two baffles 17. One end of the screw rod 18 passes through the slide plate 9 and is threadedly connected to the slide plate 9. The screw rod 18 is located below the mounting tube 6. At this time, the two baffles 17 are distributed on the fixed plate 8 away from the ammonia cart 2. A hand crank 19 for driving the screw rod 18 to rotate is provided on the baffle 17 away from the ammonia cart 2.

[0028] like Figure 2 and Figure 3When it is necessary to drive the slide plate 9 close to the fixed tube 3, it is only necessary to raise the hand crank 19 to drive the screw rod 18 to rotate clockwise. At this time, one end of the screw rod 18 passes through the slide plate 9 and is threadedly connected to the slide plate 9, and the slide plate 9 is horizontally slidably connected between the two slideways 16. Therefore, when the screw rod 18 rotates clockwise, the slide plate 9 can be driven close to the fixed tube 3, and the slide plate 9 will not rotate with the screw rod 18. It is simple and convenient to use.

[0029] like Figure 2 and Figure 3 A sleeve 20 is provided on the inner wall of the mounting tube 6, and the end of the sleeve 20 away from the hose 4 extends to the outside of the mounting tube 6 and horizontally extends into the fixed tube 3. The purpose of this arrangement is that when the mounting tube 6 is clamped on the slide 9, the sleeve 20 will be aligned with the fixed tube 3. When the slide 9 and the mounting tube 6 approach the fixed tube 3 until the mounting tube 6 and the rubber sealing layer 10 are tightly pressed, the sleeve 20 will gradually be inserted into the fixed tube 3. At this time, through the cooperation of the sleeve 20 and the fixed tube 3, the mounting tube 6 can be close to the fixed tube 3 until the mounting tube 6 and the rubber sealing layer 10 are tightly pressed. The situation of falling off of the mounting tube 6 from the clamping part of the slide 9 due to external force is reduced, and at the same time, it is convenient to align and connect the mounting tube 6 with the fixing ring 3, which is simple and convenient to use.
