Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen purification, and in particular relates to a hydrogen purification device. Background Art

[0002] When petroleum thermal cracking gas is burned, its products are carbon monoxide and carbon dioxide. The carbon monoxide in the raw gas is reacted with water under high temperature conditions to generate carbon dioxide and hydrogen, and then the generated carbon dioxide and the carbon dioxide in the raw gas are removed to obtain purified hydrogen. In the above process, there may be insufficient reaction of carbon monoxide and water vapor. The incompletely reacted carbon monoxide and water vapor will remain in the raw gas and affect the purity of the hydrogen. In the subsequent steps, in the process of removing carbon dioxide through activated carbon, as the adsorption time of activated carbon increases, the adsorbed carbon will gradually tend to saturation. When the activated carbon is saturated, the activated carbon cannot be automatically replaced. If the activated carbon is not replaced in time, the continuous adsorption and removal effect of activated carbon on carbon dioxide will be reduced, thereby reducing the hydrogen purification efficiency.

[0060] refer to Figure 1-Figure 5 and Fig.10 As shown, the monitoring module 8 also includes a flow guide cover 82 and a connecting bracket 83.

The flow of hydrogen is monitored by the gas flow sensor 81. When the flow rate decreases, it means that the alumina, zeolite or activated carbon has reached adsorption saturation and can no longer participate in hydrogen purification. At this time, the gas flow sensor 81 transmits data to the external terminal to control the replacement of another group of three-stage purification modules 6, two-stage purification modules 5, and one-stage purification module 3.

[0061] Working principle: Turn on the drive motor 39 to make the filling box 31 located above rotate counterclockwise, that is, the filling box 31 located above initially contacts the secondary contact switch 311. When the filling box 31 rotates, the sealing strip frame 33 will first separate from the secondary contact switch 311. After separation, until the other sealing strip frame 33 rotates to contact the secondary contact switch 311 again, the secondary contact switch 311 transmits a signal to the external terminal, and the external terminal receives the signal and controls the drive motor 39 to close, so that the filling box 31 located above is offset from the partition plate 2, so that the upper and lower ends of the filling box 31 are not blocked by the sealing plate 38 and the partition plate 2 located above, and the hydrogen is purified in turn through the third-stage purification module 6 on the left, the secondary purification module 5, and the primary purification module 3 located above.

[0062] The raw gas is guided into the top box 61 through the main pipe 15, the branch pipe 13, the raw gas inlet pipe 12, and the secondary cover body 63 located above. The moisture in the raw gas is adsorbed by the alumina between the two groups of three-stage screens 62 in the top box 61.

[0063] The raw gas after moisture removal enters the primary cover body 53 located above through the secondary cover body 63 located below and the secondary conduit 11, and the carbon monoxide in the raw gas is adsorbed by the zeolite between the two groups of secondary screens 52 in the middle box 51.

[0064] The raw gas after removing carbon monoxide enters the outer cylinder 1 through the first-level cover body 53, the first-level conduit 9, and the bevel ring 41 located at the bottom, and passes through the filling box 31 located at the top, so that the raw gas can pass through the outer cylinder 1. When the raw gas passes through the activated carbon between the two groups of first-level screens 32 in the filling box 31, the carbon dioxide is adsorbed by the activated carbon.

[0065] After the water, carbon monoxide and carbon dioxide in the raw gas are adsorbed and purified to obtain hydrogen, the hydrogen is discharged through the guide cover 82, and the flow of hydrogen is monitored by the gas flow sensor 81. When the flow decreases, it means that the alumina, zeolite or activated carbon has reached adsorption saturation and can no longer participate in the purification of hydrogen.

[0066] At this time, the gas flow sensor 81 transmits data to the external terminal, which receives the data and controls the three-stage solenoid valve 14 on the left, the two-stage solenoid valve 10 on the left, and the six-stage solenoid valve 713 on the right to close, and the three-stage solenoid valve 14 on the right, the two-stage solenoid valve 10 on the right, and the six-stage solenoid valve 713 on the left to open, and controls the drive motor 39 located below to open, so that the filling box 31 located below rotates counterclockwise, that is, the filling box 31 located below initially contacts the two-stage contact switch 311, and when the filling box 31 rotates, the filling box 31 and the sealing strip frame 33 will first separate from the two-stage contact switch 311, and after separation, until the other sealing strip frame 33 rotates to contact the two-stage contact switch 311 again, at this time the two-stage contact switch 311 transmits the signal to Peripheral terminal, the peripheral terminal receives the signal and controls the drive motor 39 to turn off, so that the filling box 31 located above is offset from the partition plate 2, and at the same time controls the drive motor 39 located above to turn on, so that the filling box 31 located above is reversed. During this process, the sealing strip frame 33 is separated from the secondary contact switch 311, and the other sealing strip frame 33 contacts again, and at the same time triggers the plate 34 to contact the primary contact switch 37. The peripheral terminal receives the signal from the primary contact switch 37 and the secondary contact switch 311, and controls the drive motor 39 located above to turn off, so that the hydrogen purification device is changed to purify hydrogen through the third-level purification module 6 on the right, the second-level purification module 5, and the first-level purification module 3 located below, completing the replacement of two groups of third-level purification modules 6, secondary purification modules 5, and primary purification modules 3.

[0067] After the replacement is completed, the first-level solenoid valve 73 on the left, the fourth-level solenoid valve 78 on the top, and the fifth-level solenoid valve 711 on the top are opened, and the hot air is guided to the filling box 31 on the top through the air intake pipe 72, the second-level hollow ring 71, the dispersion chamber 75, and the connecting pipe 77 to regenerate the activated carbon at high temperature.
