[0040] The filter assembly is located at the exhaust port of the cone;

[0041] The conveying component is located on one side of the cylinder, with one end extending into the inner side of the cylinder and located at the bottom of the inner side of the cylinder, and the other end connected to the external ammonia storage device to convey ammonia into the cylinder body 1.

[0042] In this embodiment, the cylinder is connected to an external dilute sulfuric acid conveying device, allowing the dilute sulfuric acid to be conveyed to the inside of the cylinder. The liquid level of the dilute sulfuric acid is always higher than the bottom of the conveying component. At the same time, the conveying component is connected to an external ammonia storage device, allowing ammonia to be conveyed to the inside of the cylinder body 1.

Simultaneously, the reacting gas is guided to the filter component through the cone, and the gas is filtered while passing through the filter component, ensuring thorough gas discharge.

[0043] Example 2

[0048] In this embodiment, a cavity with an open top is provided in the middle of the cylinder body 1, and the inlet pipe 3 connects the cavity to the external dilute sulfuric acid conveying device, so that dilute sulfuric acid is stored inside the cylinder body 1, and ammonia water is neutralized inside the cylinder body 1. The neutralized liquid inside the cylinder body 1 is discharged through the drain pipe 2, which is flush with the bottom of the inner side of the cylinder body 1.

[0049] Example 3

[0050] like Figure 1-3 As shown, the ammonia water purification device proposed in this utility model differs from the first embodiment in that the cone includes a cone body 4, an exhaust pipe 5, a connecting cap 6, and a support ring 13.

[0051] The cone body 4 is installed at the top of the cylinder body 1, and the inner diameter of the cone body 4 gradually decreases from the top of the cylinder body 1 along the height direction of the cylinder body 1.

[0052] The exhaust pipe 5 is installed at the top of the cone body 4 and is connected to the cone body 4;

[0053] The connecting cap 6 is fitted onto the outer top of the exhaust pipe 5 and extends into the middle of the exhaust pipe 5 and is connected to the filter assembly.

[0054] The support ring 13 is located inside the exhaust pipe 5 and is connected to the filter assembly.

[0055] In an optional embodiment, the outer top of the exhaust pipe 5 is provided with an external thread 16, and the inner side of the connecting cap 6 is provided with a threaded groove 15. When the exhaust pipe 5 and the connecting cap 6 are installed together, the external thread 16 is fitted and accommodated in the threaded groove 15.

[0056] In this embodiment, the filter assembly is supported by the support ring 13, and the position of the filter assembly is defined by the connection cap 6 installed at the top of the exhaust pipe 5 through the cooperation of the threaded groove 15 and the external thread 16. By setting the pressure block 14 at the bottom middle of the connection cap 6, the connection cap 6 drives the pressure block 14 to generate a squeezing force on the filter assembly during installation, so that the filter assembly is tightly fixed to the inside of the exhaust pipe 5. At the same time, the gas inside the cylinder body 1 is guided to the exhaust pipe 5 through the cone body 4, so as to avoid gas residue inside the cylinder body 1.

[0057] Example 4

[0058] like Figure 3 As shown, the ammonia water purification device proposed in this utility model differs from the first embodiment in that the filter component includes a perforated plate 7 and an activated carbon pack 10.

[0059] There are two orifice plates 7, both of which are installed inside the exhaust pipe 5 and above the support ring 13. The surface of the orifice plate 7 has multiple through holes to allow gas to flow to the outside of the exhaust pipe 5.

[0060] The activated carbon pack 10 is placed inside the exhaust pipe 5 and between the two perforated plates 7.

[0061] In an optional embodiment, a pressure block 14 extending into the inside of the exhaust pipe 5 is provided at the bottom of the middle part of the connecting cap 6, and the bottom end of the pressure block 14 is fitted and connected to the top edge of the orifice plate 7.

[0062] In this embodiment, the activated carbon pack 10 is supported and limited by the cooperation of the perforated plate 7, the connecting cap 6, and the support ring 13, so that the activated carbon pack 10 is attached to the inner wall of the exhaust pipe 5 and fixed to the inner side of the exhaust pipe 5, so that the activated carbon pack 10 adsorbs and filters the gas flowing into the inner side of the exhaust pipe 5.

[0063] Example 5

[0064] like Figure 2As shown, the ammonia water purification device proposed in this utility model differs from the first embodiment in that the conveying component includes a main pipe 8, a pump body 9, a distribution pipe 11, and a branch pipe 12.

[0065] The main pipe 8 is installed on the side of the cylinder body 1;

[0066] The pump body 9 is installed on the outside of the cylinder body 1, with one end connected to the main pipe 8 and the other end connected to the external ammonia storage device to deliver ammonia into the cylinder body 1.

[0067] The distribution pipe 11 is located in the middle of the cylinder body 1 and is connected to the main pipe 8;

[0068] There are multiple branch pipes 12, which are arranged in a circular array at the bottom end of the distribution pipe 11 according to the center of the distribution pipe 11.

[0069] In an optional embodiment, the bottom end of the branch pipe 12 is bent, and the bottom end of the branch pipe 12 is located towards the middle of the cylinder body 1 and is arranged off-center from the center of the cylinder body 1, so that the ammonia water transported by the multiple branch pipes 12 during use can drive the dilute sulfuric acid to move in a ring around the cylinder body 1.

[0070] In an optional embodiment, the inner diameters of the main pipe 8, the distribution pipe 11, and the branch pipe 12 are arranged in descending order.

[0071] In this embodiment, ammonia water is pumped into the main pipe 8 by the pump body 9, and then pumped into the middle or bottom of the dilute sulfuric acid in the cylinder body 1 by the cooperation of the distribution pipe 11 and multiple branch pipes 12, so that the ammonia water can undergo a neutralization reaction. At the same time, the bottom ends of the branch pipes 12 are bent and arranged in an array, so that multiple branch pipes 12 can be inclined to deliver ammonia water, causing the ammonia water to move the dilute sulfuric acid inside the cylinder body 1, thereby increasing the mixing reaction rate between ammonia water and dilute sulfuric acid. Meanwhile, the inner diameter of the main pipe 8, the distribution pipe 11 and the branch pipes 12 decreases in sequence, thereby increasing the delivery speed of ammonia water into the dilute sulfuric acid, and further increasing the mixing reaction rate between ammonia water and dilute sulfuric acid.

[0072] In this invention, the orifice plate 7 and activated carbon bag 10 are supported by the support ring 13, and the connecting cap 6 is installed at the top of the exhaust pipe 5 through the cooperation of the threaded groove 15 and the external thread 16 to limit the position of the orifice plate 7. By setting the pressure block 14 at the bottom middle of the connecting cap 6, the pressure block 14 is driven by the connecting cap 6 to generate a squeezing force on the orifice plate 7 during installation, thus tightly fixing the activated carbon bag 10 to the inside of the exhaust pipe 5. At the same time, dilute sulfuric acid is transported to the cylinder body 1 through the liquid inlet pipe 3, and the liquid level of the dilute sulfuric acid is always higher than the bottom of the branch pipe 12. Meanwhile, ammonia water is pumped into the main pipe 8 through the pump body 9. The ammonia water is delivered to the middle or bottom of the dilute sulfuric acid in the cylinder body 1 through the cooperation of the distribution pipe 11 and multiple branch pipes 12. The branch pipes 12 are arranged in an array with bends at the bottom. The inner diameter of the main pipe 8, the distribution pipe 11 and the branch pipes 12 decreases in sequence, so that the ammonia water delivered by the branch pipes 12 moves in the dilute sulfuric acid and undergoes a neutralization reaction during the movement. At the same time, the connecting cap 6 guides the ammonia gas in the cylinder body 1 to the exhaust pipe 5 for discharge. Meanwhile, the activated carbon bag 10 adsorbs and filters the flowing ammonia gas in the exhaust pipe 5, and the liquid discharged from the cylinder body 1 by the drain pipe 2.

[0073] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
