[0024] The following is combined with Figure 1-5 This application is described in further detail.

[0025] The present application embodiment discloses a bidirectional liquid-sealed respirator for ammonia water storage tank for denitration. Figure 1 and Figure 2 In this embodiment, the two-way liquid-sealed respirator for the ammonia water storage tank for denitration includes a shell 1, a water injection pipe 2, a drainage pipe 3 and a hydraulic balance pipe group. The shell 1 is a cylindrical structure, and the shell 1 is installed on the top of the storage tank 6. The storage tank 6 is used to store ammonia water, and a hydraulic balance pipe group is arranged between the shell 1 and the storage tank 6. The hydraulic balance pipe group can balance the pressure difference inside and outside the storage tank 6.

[0026] At the same time, the water injection pipe 2 is installed on the outer top of the shell 1 through the disassembly and assembly device, and the water injection pipe 2 is installed with a water injection valve, and the water injection pipe 2 is connected with the external water injection pipe 2, so as to inject the absorption liquid into the shell 1; the drainage pipe 3 is also installed at the bottom of the shell 1 through the disassembly and assembly device, and the drainage pipe 3 is installed with a drainage valve, and the drainage pipe 3 is connected with the external drainage pipe 3, so as to uniformly drain the absorption liquid in the shell 1. In addition, in this embodiment, the absorption liquid is clean water, and ammonia is very soluble in water.

[0027] Therefore, by setting the structure in which the water injection pipe 2, the water injection valve, the drain pipe 3 and the drain valve cooperate with each other, the valves to be operated are fewer, and the operation steps are simple and convenient. By setting the disassembly and assembly device, the water injection pipe 2 and the drain pipe 3 can be effectively and conveniently disassembled and assembled, thereby reducing the situation in which the water injection pipe 2 and the drain pipe 3 will age and leak after long-term use. At the same time, by cooperating with the hydraulic balance pipe group and utilizing the property that ammonia is highly soluble in water, the absorption liquid in the shell 1 can absorb the overflowed ammonia to avoid ammonia leakage, and can also absorb sparks or other impurities entering from the outside, thereby ensuring the safety of the storage tank 6.

[0028] Specifically, refer to Figure 3 In this embodiment, the hydraulic balance pipe group includes a first curved pipe 7 and a second curved pipe 8. The first curved pipe 7 and the second curved pipe 8 are both U-shaped structures, and are both installed on the top of the shell 1, and the first curved pipe 7 and the second curved pipe 8 are arranged crosswise with each other. The top of the first curved pipe 7 is connected to the outside air through the pipe 73, so that the outside air can enter the first curved pipe 7 along the pipe 73, or the gas in the shell 1 can be discharged to the outside along the pipe 73 and the first curved pipe 7, so as to achieve balanced gas circulation.

[0029] A connecting pipe 83 is connected to the middle of the bottom end of the second curved pipe 8. One end of the connecting pipe 83 away from the second curved pipe 8 passes through the shell 1 and is connected to the top of the storage tank 6. The connecting pipe 83 and the shell 1 are sealed and welded to prevent leakage of the absorption liquid in the shell 1. By providing the connecting pipe 83, the gas in the storage tank 6 can be discharged into the second curved pipe 8 along the connecting pipe 83, or the gas in the shell 1 can be discharged into the storage tank 6 along the second curved pipe 8 and the connecting pipe 83, thereby achieving balanced gas circulation.

[0030] At the same time, refer to Figure 3 , partitions 9 are installed between the two outer side walls of the connecting pipe 83 and the two inner side walls of the shell 1. The two partitions 9 separate the interior of the shell 1 into a first cavity 91 and a second cavity 92, and the tops of the two partitions 9 are fixedly connected to the top of the interior of the shell 1, and a gap is left between the bottoms of the two partitions 9 and the bottom of the interior of the shell 1, so that the bottom of the first cavity 91 and the bottom of the second cavity 92 are connected to each other. In this way, you only need to inject water into the shell 1, that is, you can inject water into the first cavity 91 and the second cavity 92 at the same time; and when drainage is needed, the water in the first cavity 91 and the second cavity 92 can be drained away at the same time, so that the effect of rapid water injection and drainage can be achieved, making the operation more convenient.

[0031] Preferably, visual liquid level gauges 12 are symmetrically installed on the outer wall of the shell 1. The two visual liquid level gauges 12 are respectively connected to the first cavity 91 and the second cavity 92 to measure the liquid positions in the first cavity 91 and the second cavity 92, respectively, so that the operator can more conveniently and intuitively see the liquid levels in the first cavity 91 and the second cavity 92 at this time.

[0032] In addition, refer to Figure 3 In this embodiment, a first liquid-submerged tube 71 and a first liquid-surface tube 72 are respectively connected to both ends of the first curved tube 7, and an end of the first liquid-submerged tube 71 away from the first curved tube 7 extends into the bottom of the first cavity 91, and an end of the first liquid-surface tube 72 away from the first curved tube 7 extends into the top of the second cavity 92; a second liquid-submerged tube 81 and a second liquid-surface tube 82 are respectively connected to both ends of the second curved tube 8, and an end of the second liquid-submerged tube 81 away from the second curved tube 8 extends into the bottom of the second cavity 92, and an end of the second liquid-surface tube 82 away from the second curved tube 8 extends into the top of the first cavity 91.

[0033] In this way, by arranging the structures of the first curved tube 7, the first submerged tube 71, the first supra-liquid tube 72, the second curved tube 8, the second submerged tube 81 and the second supra-liquid tube 82 that cooperate with each other, and by combining the connecting tube 83 and the pipeline 73, the pressure difference inside and outside the storage tank 6 can be balanced, and then by utilizing the pressure difference, not only can the ammonia overflowing from the storage tank 6 be absorbed to avoid ammonia leakage; but also sparks or other impurities entering from the outside can be absorbed, thereby ensuring the safety of the storage tank 6.

[0034] When ammonia water is injected into the storage tank 6, the liquid level in the storage tank 6 rises, and the air in the storage tank 6 is squeezed out. The air carries some volatile ammonia. When the ammonia passes through the hydraulic balance pipe group in the respirator, under the action of the hydraulic balance pipe group, the ammonia will pass through the absorption liquid in the shell 1. The absorption liquid is clean water. Since ammonia is highly soluble in water, it can absorb a large amount of ammonia to prevent leakage of ammonia, thereby completing the exhalation process of the respirator.

[0035] When ammonia water is transported out, the liquid level in the storage tank 6 drops, and outside air needs to enter the storage tank 6 to balance the pressure. In the process of outside air entering the storage tank 6 from the outside, it will come into contact with the absorption liquid in the respirator. The absorption liquid is clean water, which will absorb sparks or other impurities, thereby ensuring the safety of the storage tank 6 and completing the inhalation process of the respirator.

[0036] The following is a detailed description of the disassembly and assembly device between the drain pipe 3 and the housing 1:

[0037] Reference Figure 4 and Figure 5In this embodiment, the disassembly and assembly device includes a fixing seat 4, a disassembly and assembly seat 5 and a sealing limit mechanism. The fixing seat 4 is installed at the bottom of the housing 1, and a fixing slot 41 is provided on the fixing seat 4. A water hole 11 is provided at the bottom of the housing 1, and the water hole 11 corresponds to the fixing slot 41; the disassembly and assembly seat 5 is fixedly sleeved on the outer side of one end of the drain pipe 3, and the disassembly and assembly seat 5 cooperates with the fixing slot 41, so that the pipe mouth of the drain pipe 3 corresponds to the water hole 11, so as to facilitate drainage.

[0038] The sealing limit mechanism is arranged between the disassembly seat 5 and the fixing seat 4, so as to facilitate the disassembly seat 5 to be tightly mounted on the fixing seat 4. Figure 1 In this embodiment, the sealing limit mechanism includes an annular block 51, an annular strip 52 and a clamping assembly. The annular block 51 is fixedly mounted on the side of the disassembly seat 5 facing the fixed seat 4, and the annular block 51 is sleeved on the outer side of one end of the drain pipe 3; there are multiple annular strips 52, which are fixedly mounted on the side of the annular block 51 away from the disassembly seat 5, and the multiple annular strips 52 are respectively located on the outer side of the drain pipe 3 with the drain pipe 3 as the central axis, and multiple annular grooves 42 are also opened on the hole wall of the fixed slot hole 41, and the annular grooves 42 and the annular strips 52 cooperate with each other.

[0039] When the disassembly seat 5 cooperates with the fixed slot hole 41, the annular block 51 presses against the hole wall of the fixed slot hole 41, and the annular strip 52 is engaged in the annular groove 42, so that the disassembly seat 5 and the fixed seat 4 are tightly matched to reduce water leakage and air leakage.

[0040] Preferably, in this embodiment, the annular block 51 is a rubber block, and the annular strip 52 is a rubber strip, so that when the disassembly seat 5 and the fixed seat 4 cooperate with each other, the annular block 51 and the hole wall of the fixed slot hole 41 are more tightly abutted, and the annular strip 52 and the annular slot 42 are more tightly engaged, thereby further improving the tightness between the disassembly seat 5 and the fixed seat 4.

[0041] Meanwhile, the clamping assembly is arranged between the disassembly seat 5 and the fixed seat 4, and the clamping assembly includes a first clamping block 43 and a second clamping block 53. There are two first clamping blocks 43, which are symmetrically mounted on the side of the fixed seat 4 away from the housing 1; and there are two second clamping blocks 53, which are symmetrically mounted on the side of the disassembly seat 5 away from the annular strip 52, and a clamping groove 431 is provided on the corresponding side of the two first clamping blocks 43, and the two second clamping blocks 53 are respectively clamped with the two clamping grooves 431, so as to fix the disassembly seat 5 in the fixed slot hole 41 of the fixed seat 4.

[0042] In addition, refer to Figure 4 and Figure 5In this embodiment, a sliding groove 432 is provided inside the first clamping block 43 on the side away from the fixing seat 4. The sliding groove 432 is connected to the clamping groove 431. A spring 45 is connected to the groove wall of the end of the sliding groove 432 away from the clamping groove 431. The other end of the spring 45 is fixedly connected to the sliding block 44. The sliding block 44 cooperates with the sliding groove 432 so that the sliding block 44 can move in the sliding groove 432. When the spring 45 is in a normal state, one side of the sliding block 44 extends out of the sliding groove 432; when the sliding block 44 is squeezed, the sliding block 44 squeezes the spring 45 so that the spring 45 contracts.

[0043] At the same time, a first inclined surface is provided on the side of the sliding block 44 away from the spring 45 , and a second inclined surface is provided on the side of the second clamping block 53 away from the disassembly seat 5 , and the second inclined surface and the first inclined surface cooperate with each other. When the disassembly and assembly seat 5 is installed in the fixed slot hole 41 of the fixed seat 4, the disassembly and assembly seat 5 is rotated so that the disassembly and assembly seat 5 drives the second clamping block 53 to enter the clamping slot 431 of the first clamping block 43, so that the second clamping block 53 moves along the clamping slot 431, and then the second inclined surface on the second clamping block 53 and the first inclined surface of the sliding block 44 are pressed against each other to squeeze the sliding block 44, so that the sliding block 44 squeezes the spring 45 along the sliding slot 432, so that the spring 45 shrinks and deforms, thereby making the sliding block 44 slide into the sliding slot 432, and then the rotation of the disassembly and assembly seat 5 is stopped. At this time, the sliding block 44 is pressed against the second clamping block 53 under the elastic action of the spring 45, so that the disassembly and assembly seat 5 can be further effectively squeezed, thereby making the disassembly and assembly seat 5 and the fixed seat 4 closer.

[0044] In addition, refer to Figure 4 In this embodiment, a first sealing groove 54 is further provided on the outer side wall of the disassembly seat 5, and a sealing ring 55 is installed in the first sealing groove 54. The sealing ring 55 is a waterproof rubber ring with good sealing effect. A second sealing groove 46 is further provided on the inner side wall of the fixed slot hole 41. The second sealing groove 46 and the sealing ring 55 cooperate with each other. When the disassembly seat 5 is installed into the fixed slot hole 41 of the fixed seat 4, the sealing ring 55 in the first sealing groove 54 is sealed and clamped into the second sealing groove 46, thereby achieving a tight sealing effect.

[0045] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
