DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0022] Reference Figure 1-4 A recyclable adsorption tower device for producing hydrogen from coke oven gas, comprising a treatment cylinder 1, a circulation component 2 is installed on the top outer wall of the treatment cylinder 1, and a feed hopper 3 is installed on the bottom outer wall of the treatment cylinder 1, an input pipe 4 is connected to the bottom center of the feed hopper 3, and a collecting cylinder 5 is installed at the bottom center of the feed hopper 3, and an outer wall of one side of the treatment cylinder 1 is provided with mounting grooves 6 distributed at equal distances, and adsorption structures 7 are installed in the mounting grooves 6. The gas inside the treatment cylinder 1 contains some impurities. With the filtering and interception of the filter net 11, the impurities will fall into the feed hopper 3 as accumulated, and fall into the collecting cylinder 5 for collection, and the impurities inside the collecting cylinder 5 are cleaned regularly, which is convenient for cleaning and gas treatment;

[0023] The adsorption structure 7 includes a fixed frame 9, a limiting ring 10 welded to the bottom of the inner outer wall of the fixed frame 9, a filter 11 placed on the outer wall of the top of the limiting ring 10, a filter 12 placed on the outer wall of the top of the fixed frame 9, and a limiting ring 14 welded to the outer wall of the top of the filter 12. When in use, the flow sensor 13 detects the gas flow inside each fixed frame 9. If the flow rate decreases, the adsorption filter material at the position where the flow rate decreases is replaced, which is convenient for judging the adsorption capacity of the adsorption filter material and facilitating timely replacement;

[0024] A flow sensor 13 is installed at the center of the inner outer wall of the fixed frame 9, and the second filter screen 12 is placed on the top outer wall of the fixed frame 9 through the second limit ring 14;

[0025] The outer wall of the treatment cylinder 1 is provided with a sealing groove 8 at the installation groove 6, and a sealing plate 15 is welded to the outer wall of one end of the fixing frame 9 at the sealing groove 8, and a sealing gasket is bonded to the outer wall of the sealing plate 15 on one side close to the sealing groove 8;

[0026] A handle groove is provided at the center of the outer wall of one side of the sealing plate 15, and fixing rings are welded to the outer walls at both ends of the sealing plate 15. The inner wall of the fixing ring is slidably connected with screws, and the screws are threaded in the treatment cylinder 1. The fixing frame 9 is fixed in the treatment cylinder 1 through the sealing plate 15 and the screws, which is convenient for replacement and ensures the stability of the installation. The sealing gasket ensures the sealing of the connection to avoid leakage. Example

[0027] Reference Figure 1-2 The circulation assembly 2 includes an exhaust hopper 17, an exhaust pipe 18 connected to the center of the top of the exhaust hopper 17, and a circulation pipe 19 connected to the outer wall of one side of the exhaust hopper 17;

[0028] An air sensor 21 is installed on the inner wall of one side of the exhaust hopper 17, and the other end of the circulation pipe 19 is connected to one side of the treatment tube 1. The exhaust pipe 18 and the circulation pipe 19 are both installed with a solenoid valve 20 at one end. The air sensor 21 in the exhaust hopper 17 detects the air content after adsorption, and activates the solenoid valve 20 in the exhaust pipe 18 and the circulation pipe 19 according to the content, which is convenient for discharge and circulation of the treated gas;

[0029] The outer wall of the treatment cylinder 1 and the outer wall of the feed hopper 3 are both installed with support legs, and the outer wall of one of the support legs is installed with a controller 16, and the flow sensor 13 and the air sensor 21 are connected to the signal input end of the controller 16 through a signal line;

[0030] The solenoid valve 20 is connected to the controller 16 via a wire, and the controller 16 is connected to a power source via a wire.

[0031] Working principle: When in use, connect one end of the equipment discharge to one end of the input pipe 4. After the equipment discharges, the gas enters the feed hopper 3 through the input pipe 4. As the gas enters, the gas passes through multiple fixed frames 9 from bottom to top, and raw materials for adsorption are added inside the fixed frames 9. As the gas rises, the adsorption raw materials gradually adsorb the harmful substances in the gas. Then the gas enters the exhaust hopper 17. The air sensor 21 detects the gas in the exhaust hopper 17. The gas is discharged from the exhaust pipe 18 after meeting the emission standards. If the gas does not meet the emission standards, the solenoid valve 20 on the exhaust pipe 18 is closed, and the solenoid valve 20 on the circulation pipe 19 is opened. The gas on the exhaust hopper 17 is guided to the fixed frames 9 of the last two layers through the circulation pipe 19, and the gas is circulated and adsorbed. The circulated processed gas ensures that the emission meets the standards.

[0032] When replacing the adsorption raw material, remove the screws on the fixing ring and pull out the sealing plate 15 and the fixing frame 9 from the mounting groove 6 and the sealing groove 8 through the handle groove, remove the filter screen 12 upwards, and then take out the filter screen 11 connected to the adsorption filter material from the fixing frame 9, clean the filter screen 11 and replace the filter screen 11, and then lay the adsorption filter material on the top of the filter screen 11, and finally place the filter screen 12 on the top of the fixing frame 9, and return the fixing frame 9 to complete the replacement, which is convenient for replacing the adsorption filter material.
