Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace gas purification, and particularly relates to a blast furnace gas desulfurization device. Background Technique

[0002] Blast furnace gas is a mixed gas containing various gases generated during the process of smelting iron ore in a blast furnace, mainly including hydrogen, carbon monoxide, carbon dioxide and nitrogen. Blast furnace gas desulfurization is to remove sulfides in blast furnace gas through chemical reactions to reduce environmental pollution and improve the quality of the gas. At the same time, it can effectively reduce the emission of sulfides, reduce environmental pollution and improve the utilization efficiency of the gas.

[0003] When the traditional device is in use, first prepare the desulfurization liquid, place the desulfurization liquid at the bottom of the box body, and then transport the blast furnace gas into the box body to make it contact with the desulfurization liquid, so that the blast furnace gas can be effectively desulfurized. Then, it is further sprayed through the spraying system, and finally the desulfurized blast furnace gas is obtained. However, it is difficult to observe the liquid level of the desulfurization liquid inside the box body during the desulfurization process. When the spraying system extracts the desulfurization liquid, it is easy to cause the situation that the liquid level of the desulfurization liquid in the box body is insufficient, which greatly affects the desulfurization reaction efficiency, resulting in poor desulfurization effect and difficulty in completely removing hydrogen sulfide in the gas. At the same time, the inability to observe the liquid level will cause the liquid level to be too low, resulting in the desulfurization liquid inside the box body not covering the reaction area, affecting the desulfurization effect, or the liquid level being too high, which is easy to cause liquid overflow or damage to the equipment.

[0032] Please refer to Figure 2 , Figure 3 and Figure 4, Observation mechanism 2, which is located on one side of the box body 1 and is used to observe the liquid level of the desulfurization liquid inside the box body 1. The observation mechanism 2 includes a connection mechanism, a buoyancy mechanism, a positioning mechanism, and a display mechanism.
