[0002] In recent years, with the development of high-tech industries such as electronics and materials, the market demand for special gases in air separation plants has been increasing year by year. The special gases in air separation plants currently referred to in the market are high-purity oxygen, nitrogen, and rare gases (argon, neon, helium, krypton, xenon). These gases are mainly obtained by by-products of air separation through cryogenic separation. More than 80% of the global market is occupied by industrial gas giants such as Air Liquide and Linde. The production process of rare gases in China has only made breakthroughs in recent years.

[0003] The existing rare gas purification and separation device needs to first filter and purify the air through a pre-filter box and then pressurize the gas to cool and liquefy it into the main tower. The liquefied air is heated by a heating device installed inside the main tower, so that rare gases with different boiling points boil and evaporate at different temperatures, thereby realizing the separation and purification of rare gases.

[0004] During the long-term use of the existing rare gas purification and separation device, dust in the air may block the sieve plates in the pre-filter box, thereby affecting air circulation. Cleaning the sieve plates is time-consuming and laborious, thus affecting the efficiency of gas entering the main tower for compression and purification. Content of the Utility Model

[0023] Please refer to Figures 1-5The utility model provides an embodiment: a rare gas purification and separation device, including a main tower 1 and a filter box 2, an air intake pipe 6 is plugged into the side wall of the main tower 1, and a flange ball valve 7 is installed at the end of the air intake pipe 6 through a flange connection. An inner liner 20 is fixed inside the main tower 1, and a coil 21 is wound around the outer surface of the inner liner 20. The air intake pipe 6 runs through the main tower 1 and is connected to the inside of the inner liner 20. The coil 21 is connected to a power supply so that the inner liner 20 can be evenly heated, so that the temperature inside the inner liner 20 is increased to reach different temperatures to facilitate the rare gases with different boiling points. The main tower 1 is sleeved on the outer surface of the inner tank 20 to insulate and protect the inner tank 20. The top of the main tower 1 is plugged with an exhaust pipe 8. The bottom end of the exhaust pipe 8 runs through the main tower 1 and the inner tank 20. The inner top of the inner tank 20 is fixed with a temperature sensor 22 to improve the accuracy of temperature control. The other end of the flange ball valve 7 is installed with a solenoid valve to improve the convenience of rare gas discharge. The side wall of the filter box 2 near the flange ball valve 7 is fixed with a compressed air pump 5 by bolts. The compressed air pump 5 is connected to the filter box 2 and the flange ball valve 7 through pipelines in turn. Open the flange ball valve. The valve 7 can connect the inner tank 20 and the filter box 2. Starting the compressed air pump 5 can compress and liquefy the air filtered by the filter box 2 and discharge it into the inner tank 20. An air intake grille 9 is fixedly provided on the side wall of the filter box 2 away from the compressed air pump 5. The air intake grille 9 is used to block large particles of impurities in the air. Two sieve plates 10 are clamped on the inner side wall of the main tower 1. The sieve plates 10 are all made of metal and are in a grid shape to filter dust in the air. A top plate 3 is fixedly provided on the top of the filter box 2. A cylinder 4 is fixedly provided on the top of the top plate 3. The output end of the cylinder 4 passes through the top plate 3 and is fixedly provided with a support plate 1 1. Brushes 12 are embedded on the side walls of the support plate 11 close to the two sieve plates 10. A card slot 3 18 is opened at both ends of the support plate 11. Two vibration motors 19 are symmetrically fixed on the inner bottom of the card slot 3 18. When the surface of the sieve plate 10 absorbs more dust and impurities, the operator can start the cylinder 4 to move vertically, thereby driving the two brushes 12 to clean the dust attached to the surface of the sieve plate 10. Starting the vibration motor 19 again can drive the brush 12 and the sieve plate 10 to generate high-frequency vibration, thereby improving the efficiency of cleaning the dust from the surface of the sieve plate 10.

[0024] A filter element 13 is clamped inside the filter box 2 near the compressed air pump 5. The filter element 13 is made of activated carbon filter cotton. The mesh of the filter element 13 is honeycomb-shaped to further filter impurities in the air, thereby improving the quality of air filtration.

[0025] Two clamping grooves 16 are symmetrically provided on the inner side wall of the filter box 2 for clamping the sieve plate 10 . The outer dimensions of the sieve plate 10 are matched with the inner dimensions of the clamping grooves 16 in turn, which improves the convenience of installing and positioning the sieve plate 10 .

[0026] A bottom plate 14 is inserted near the bottom end of the filter box 2 close to the sieve plate 10. A second clamping groove 17 is formed in the side wall of the filter box 2 below the first clamping groove 16. The second clamping groove 17 penetrates through the side wall of the filter box 2 for the bottom plate 14 to be clamped. The internal dimension of the bottom plate 14 is adapted to the external dimension of the second clamping groove 17, which improves the convenience of installing the bottom plate 14. A hopper 15 is fixedly provided at the bottom end of the filter box 2. The hopper 15 is funnel-shaped and communicates with the inside of the filter box 2. The operator can draw out the bottom plate 14 to connect the hopper 15 and the main tower 1, so as to facilitate the discharge of the swept dust through the hopper 15, and improve the convenience of discharging dust particles.

[0027] Working principle: When this rare gas purification and separation device is in use, the operator first externally connects the power supply and opens the flange ball valve 7 to connect the inner tank 20 and the compression air pump 5. Starting the compression air pump 5 can pump air from the air inlet grille 9 into the inside of the filter box 2. After the air is filtered by the two sieve plates 10 and the filter element 13, it is compressed and liquefied and then enters the inside of the inner tank 20. By connecting the power supply of the coil 21, the inner tank 20 can be heated. According to the different boiling points of the liquefied gas, it is heated to different temperatures, so that different rare gases boil and evaporate at different temperatures. Opening the exhaust pipe 8 can discharge the rare gas at the corresponding boiling point, so as to realize the purification of rare gases. When more dust impurities are adsorbed on the surface of the sieve plate 10, the operator can start the cylinder 4 to move vertically, so as to drive the two brushes 12 to clean the dust attached to the surface of the sieve plate 10. Starting the vibration motor 19 again can drive the brushes 12 and the sieve plate 10 to generate high-frequency vibration, thus improving the efficiency of cleaning dust from the surface of the sieve plate 10.

[0028] Secondly, the external dimension of the bottom plate 14 is adapted to the internal dimension of the second clamping groove 17, which improves the installation stability of the bottom plate 14. The operator can draw out the bottom plate 14 to connect the hopper 15 and the main tower 1, so as to facilitate the discharge of the swept dust through the hopper 15.
