Description

Technical Field

[0001] The utility model belongs to the technical field of adsorption towers, in particular to a coal gas dry acid removal adsorption tower. Background Art

[0002] Gas containing acidic corrosive media such as chlorine and sulfur causes rapid corrosion and failure of gas pipelines and ancillary equipment, affecting the safety and normal production and operation of the gas system. At present, the industry generally uses adsorption towers to adsorb chlorine and sulfur in coal gas. The methods used to remove acidic corrosive media such as chlorine and sulfur include wet scrubbing and dry adsorbent adsorption technology, which has the advantages of environmental protection and energy saving without water spraying, cooling, and generating new pollution sources.

[0003] The utility model patent with the patent application publication number 201220596050.7 discloses a multi-channel coal gas dry deacidification adsorption tower, which includes an inlet valve group, an inlet section, an adsorption section, an outlet section and an outlet valve group arranged in sequence, and the adsorption section is provided with a polygonal airflow combination channel, and the polygonal airflow combination channel is built with a dry adsorbent for removing chlorine, sulfur and ammonia.
