[0026] Example 1: An industrial hydrogenation device for a flare gas system, such as Figures 1-5 As shown, the system includes a bubbling desulfurization tower 1 installed at the end of the flare gas emission system. The bubbling desulfurization tower 1 is located between the flare gas emission system and the heating furnace, and the gas outlet of the bubbling desulfurization tower 1 is connected to the heating furnace. The flare gas emission system, the bubbling desulfurization tower 1, and the heating furnace are combined to form a material-saving channel. The flare gas emission system is equipped with a pneumatic valve for pressure adjustment, and the bubbling desulfurization tower 1 is equipped with a receiving bin inside, which is used to limit the flow of impurities inside the bubbling desulfurization tower 1.

[0027] With the support of pneumatic valve regulation and the clean flow guidance of the bubbling desulfurization tower 1, the device can adjust the flare gas pressure, change the combustion mode, and ensure the safety of the combustion gas. This allows a portion of the flare gas to be used as fuel in the heating furnace, reducing natural gas consumption. Specifically, the bubbling desulfurization tower 1 purifies the gas in the process, ensuring emission standards. With the support of the pneumatic valve, the flare gas pressure is adjusted from 5 kPa to 8 kPa to open the first-stage burner pneumatic valve. By connecting the bubbling desulfurization tower 1 to the heating furnace, a portion of the flare gas is used as fuel in the heating furnace for combustion. The bubbling desulfurization tower 1 further purifies the gas, thus reducing natural gas consumption. The purification process before emission achieves energy conservation and environmental protection.

[0028] likeFigures 1-5 As shown, the lower half of the outer side of the bubble-type desulfurization tower 1 is connected and provided with a gas inlet 2 for supporting the torch gas inflow, and the bubble-type desulfurization tower 1 is connected with the torch gas discharge system end pipeline through the gas inlet 2.

[0029] The top end of the bubble-type desulfurization tower 1 is connected and provided with a gas outlet 3 for guiding the desulfurized gas discharge, and the gas outlet 3 is connected with the heating furnace through the flow pipeline.

[0030] With the connection of the gas inlet 2 and the gas outlet 3 to the torch gas discharge system and the heating furnace respectively, the stability and high efficiency of the bubble-type desulfurization tower 1 in supporting the flow of the two sides during operation are ensured, and the reliability of the continuous operation of the overall process of the device is ensured.
