These methods have limitations when dealing with complex gas mixtures. For example, a single adsorbent may not be able to effectively remove all types of impurities, while chemical reaction methods may require specific conditions to achieve efficient purification. Therefore, a multi-stage separation gas purification device is proposed. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 This embodiment of a multi-stage gas purification device includes a base 1 and a cyclone generator 2. From left to right, a collection box 3, a separation tank 4, and a reaction tank 5 are fixed on the upper surface of the base 1. The lower surface of the separation tank 4 is connected to a first air inlet pipe 6. The separation tank 4 is equipped with a filter mechanism 7. The output end of the cyclone generator 2 is connected to the bottom end of the first air inlet pipe 6. The input end of the cyclone generator 2 is connected to a second air inlet pipe 8. The upper surface of the reaction tank 5 is connected to an output pipe 9.

[0018] In this embodiment, the right side of the collection box 3 is connected to the left side of the lower surface of the separation tank 4 via a pipe. The left side of the collection box 3 is connected to a first discharge structure 10, which includes a first discharge pipe. The outer side of the left side of the first discharge pipe is connected to a first valve, and the inside of the first valve is connected to a second discharge pipe. The right side of the reaction tank 5 is connected to a second discharge structure 11, which includes a third discharge pipe. The outer side of the right side of the third discharge pipe is connected to a second valve, and the inside of the second valve is connected to a fourth discharge pipe. The left side of the upper surface of the reaction tank 5 is connected to an inlet pipe, and a sealing cap is threaded to the outer side of the top of the inlet pipe.

[0019] Specifically, the bottom end of the second air inlet pipe 8 is connected to an external air inlet pipe. When the device is turned on, the gas enters the interior of the cyclone generator 2 through the second air inlet pipe 8. Then, the gas rotates upward at high speed and enters the interior of the separator 4 through the first air inlet pipe 6. The gas rotates at high speed inside the separator 4 and generates centrifugal force, separating the liquid droplets and dust in the gas. The liquid droplets and dust flow into the interior of the collection box 3 through the inner peripheral wall and pipe of the separator 4.

[0020] Please see Figures 2 to 3 In this embodiment, the filtration mechanism 7 includes a limiting ring 701 fixed inside the separation tank 4. An annular filter frame 702 is placed on the upper surface of the limiting ring 701. A detachable first filter screen 703 and an activated carbon filter screen 704 are fixed inside the annular filter frame 702 from bottom to top. A rubber sealing ring 705 is fixed on the outer side of the annular filter frame 702. Fixing rods 706 are fixed on both the left and right sides of the upper surface of the annular filter frame 702. A sealing plate 707 is fixed to the upper surface of the separation tank 4 by bolts. Abutment rods 708 are fixed on both the left and right sides of the lower surface of the sealing plate 707. The bottom ends of the abutment rods 708 on both sides abut against the left and right sides of the upper surface of the annular filter frame 702. The upper surface of the sealing plate 707 passes through the reaction tank 5 through a movable pipe and extends into the interior.

[0021] Specifically, the outer diameter of the rubber sealing ring 705 is matched with the inner diameter of the separation tank 4. The sealing plate 707 includes a fixing plate, and a sealing rubber layer is fixed on the lower surface of the fixing plate. The sealing plate 707 can be disassembled by twisting the threads on the left and right sides of the upper surface of the sealing plate 707, which facilitates the maintenance and unblocking of the filter structure. This meets the requirement of high-purity gas for reaction or as a carrier gas in the pharmaceutical process.

[0022] It should be noted that the gas after centrifugal separation is initially filtered by the first filter screen 703 to remove large particulate impurities. Then, it is further purified by adsorbing odors and harmful substances in the gas through the activated carbon filter screen 704. After that, the gas enters the interior of the reaction chamber 5 through the movable pipe and reacts with the reaction liquid inside the reaction chamber 5 to further process the gas and achieve higher purity requirements. Then, it is transported out through the output pipe 9. The reaction liquid can be selected according to the composition and purity requirements of the gas to be processed. Through chemical reaction, impurities or harmful components in the gas are further removed to ultimately achieve higher purity requirements.

[0023] The working principle of the above embodiments is as follows: In use, the bottom end of the second air inlet pipe 8 is connected to the external air inlet pipe. When the equipment is turned on, the gas enters the cyclone generator 2 through the second air inlet pipe 8. Then, the gas rotates upward at high speed and enters the separation tank 4 through the first air inlet pipe 6. Inside the separation tank 4, the gas rotates at high speed and generates centrifugal force, separating liquid droplets and dust in the gas. The liquid droplets and dust flow into the collection box 3 through the inner wall and pipe of the separation tank 4. The gas separated by centrifugation passes through the first filter screen 703 for preliminary filtration of large particulate impurities in the gas. Then, it passes through the activated carbon filter screen 704 to adsorb odors, harmful substances, etc. in the gas, further purifying the gas. After that, the gas enters the reaction tank 5 through the movable pipe and reacts with the reaction liquid inside the reaction tank 5 to further process the gas to achieve higher purity requirements. Then, it is delivered out through the output pipe 9. The reaction liquid can be selected according to the composition and purity requirements of the gas to be processed. Through chemical reaction, impurities or harmful components in the gas are further removed, ultimately achieving higher purity requirements.
