Description

Technical Field

[0001] This utility model relates to the field of ammonia purification technology, and in particular to an ammonia purification device with a drying function. Background Technology

[0002] Ammonia is used to manufacture ammonia water, nitrogen fertilizers (urea, ammonium bicarbonate, etc.), compound fertilizers, nitric acid, ammonium salts, soda ash, etc., and is widely used in chemical, light industry, fertilizer, pharmaceutical, and synthetic fiber fields. Nitrogen-containing inorganic salts and organic intermediates, sulfonamide drugs, polyurethane, polyamide fibers, and nitrile rubber all require ammonia as a raw material. In addition, liquid ammonia is commonly used as a refrigerant, and ammonia can also be used as a biofuel to provide energy.

[0003] In the nitriding process, ammonia is often used as a raw material to provide nitrogen atoms. Since the ammonia in the ammonia tank contains moisture, it needs to be dried before entering the nitriding reactor to prevent the moisture in the ammonia from crystallizing with the salts generated by the nitriding reaction, which could cause pipe blockage. However, existing ammonia extraction devices have unsatisfactory drying efficiency and prolong the working time when drying ammonia. Therefore, it is necessary to provide an ammonia purification device with drying function to solve the above problems. Utility Model Content

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1 , Figure 2 , Figure 3 As shown, an ammonia purification device with drying function includes a purification tank 1, a connecting pipe 2 is provided on the top of the purification tank 1, and a drying component 3 is provided at one end of the connecting pipe 2.

[0024] The drying assembly 3 includes a supporting base plate 4, a drying tank 5 on top of the supporting base plate 4, an arc-shaped cleaning door 6 in the middle of the side wall of the drying tank 5, an agitator 12 in the middle of the drying tank 5, and a refrigeration unit 9 on one side of the drying tank 5. An L-shaped adapter pipe 10, a spiral condenser pipe 11, and a partition plate 8 are arranged on the side of the refrigeration unit 9. The supporting base plate 4 is bolted to the outer side wall of the purification tank 1, and the drying tank 5 is bolted to the top of the supporting base plate 4. The drying tank 5 is adjacent to the purification tank 1. A through groove 7 is formed on one outer side wall of the drying tank 5, penetrating the interior of the drying tank 5. A partition plate 8 is bolted to the inner wall of the drying tank 5 near the bottom, and the partition plate 8 is horizontally aligned with the bottom inner wall of the through groove 7. An arc-shaped cleaning door 6 is installed in the middle of the through groove 7, and the arc-shaped cleaning door 6 is rotatably connected to the drying tank 5 and sealed to the drying tank 5. The drying tank 5 is located away from the purification tank 1. A refrigeration unit 9 is bolted to the outer side wall, and the bottom of the refrigeration unit 9 is in contact with the top of the support base plate 4. An L-shaped adapter pipe 10 is installed on the side of the refrigeration unit 9 near the drying tank 5, and a spiral condenser pipe 11 is installed on the end of the L-shaped adapter pipe 10 away from the refrigeration unit 9. The spiral condenser pipe 11 is adjacent to the inner wall of the drying tank 5, and there are two L-shaped adapter pipes 10, which are symmetrically distributed at both ends of the spiral condenser pipe 11. The two ends of the spiral condenser pipe 11 are connected to the refrigeration unit 9 through two L-shaped adapter pipes 10. The refrigeration unit 9 cools the coolant, and the L-shaped adapter pipes 10 and the spiral condenser pipe 11 transfer the coolant, thereby reducing the temperature inside the drying tank 5. This causes the water vapor inside the ammonia to condense into ice crystals at a lower temperature, thus drying the ammonia. The arc-shaped cleaning door 6 facilitates the cleaning of the formed ice crystals, improving the ease of use of the device.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the stirring assembly 12 includes a drive motor 13. A rotating rod 14 is provided at the bottom of the drive motor 13, and a mounting ring 15 and a stirring rod 16 are provided on the outside of the rotating rod 14. The bottom of the drive motor 13 is bolted to the top center of the drying tank 5, and the output end of the drive motor 13 is drivenly connected to the rotating rod 14. One end of the rotating rod 14 near the drive motor 13 is mounted to the top center of the drying tank 5 via a bearing, and a mounting ring 15 is bolted to the outer wall of the rotating rod 14. The bottom end of the rotating rod 14 is located above the partition plate 8, and the outer wall of the mounting ring 15 is bolted to... The drying tank 5 is equipped with three stirring rods 16, which are evenly distributed on the outer wall of the mounting ring 15. The end of the stirring rod 16 away from the mounting ring 15 is set at a certain distance from the spiral condenser tube 11. A feed pipe 17 is installed on one side of the top of the drying tank 5, and the bottom side of the drying tank 5 is connected to the purification tank 1 through a connecting pipe 2. The connecting pipe 2 is located above the partition plate 8. The rotating rod 14 and the mounting ring 15 are driven by the drive motor 13 to rotate, so that the mounting ring 15 drives the stirring rod 16 to fully mix the ammonia gas with the lower temperature, thereby improving the drying efficiency and saving working time.

[0026] It should be noted that this utility model is an ammonia purification device with a drying function. In use, the ammonia to be dried is injected into the drying tank 5 through the feed pipe 17. The coolant is cooled by the refrigeration unit 9. The coolant is transferred through the L-shaped adapter pipe 10 and the spiral condenser pipe 11. The spiral condenser pipe 11 is located inside the drying tank 5, thereby reducing the temperature inside the drying tank 5. When the ammonia enters the drying tank 5, the water vapor inside the ammonia crystallizes at a lower temperature, causing the water vapor to condense into ice crystals. The ice crystals fall above the partition plate 8. At the same time, the drive motor 13 drives the rotating rod 14 to rotate at a constant speed, so that the rotating rod 14 drives the mounting ring 15 and the stirring rod 16 to fully mix the ammonia with the lower temperature, improving the cooling efficiency and the ease of use of the device. The dried ammonia is transferred to the purification tank 1 through the connecting pipe 2 to complete the purification of the ammonia. After completion, the arc-shaped cleaning door 6 is opened to facilitate the cleaning of the ice crystals.
