Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen sulfide waste gas adsorption experimental equipment, in particular to hydrogen sulfide waste gas adsorption experimental equipment. Background Art

[0002] Hydrogen sulfide is an acidic and toxic gas at normal temperature and pressure. Low concentrations of hydrogen sulfide gas have a smell similar to rotten eggs. In addition, hydrogen sulfide is a flammable and explosive substance. When mixed with air, it will explode under open flames and high temperatures.

[0003] At present, the commonly used method is adsorption, which uses certain substances with strong adsorption capacity, such as activated carbon, molecular sieves, diethanolamine aqueous solution, etc., to adsorb hydrogen sulfide components and then desorb them. The adsorbent can be regenerated, but most hydrogen sulfide treatment devices have not formed a circulating treatment system. The activated carbon inside is placed for long-term use. If it is not replaced, the adsorption capacity will be reduced. Therefore, it is urgent to design a hydrogen sulfide waste gas adsorption experimental equipment. Utility Model Content
