Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment of non-ferrous metallurgical furnaces, in particular to an adsorption tower cooling system. Background Technique

[0002] In the field of flue gas treatment of non-ferrous metallurgical furnaces, efficient adsorption and desorption of carbon dioxide are the key links to achieve energy conservation and emission reduction. With the continuous improvement of environmental protection requirements and the continuous progress of technology, more advanced equipment and systems are needed to ensure the stable operation of the whole treatment process.

[0003] As a key equipment for treating carbon dioxide in the flue gas of non-ferrous metallurgical furnaces, the stability and efficiency of the adsorption tower directly affect the effectiveness of the whole flue gas treatment process. During the continuous operation of the adsorption tower, since the adsorption and desorption of carbon dioxide is a process accompanied by energy changes, a large amount of heat will be generated. Without the timely intervention of the cooling system, the temperature inside the adsorption tower will continue to rise. The too high temperature will not only damage the structure of the adsorption tower and affect its service life, but also have a serious negative impact on the performance of the adsorbent. The adsorbent may lose its activity at high temperature, resulting in a significant decrease in the adsorption capacity, so that carbon dioxide cannot be effectively captured, and thus cooling equipment needs to be used to cool the adsorbent.

[0004] However, when the existing cooling equipment is in use, it is unable to control the flow rate of the gas, which is likely to cause the gas to pass through the cooling equipment too fast or too slow, resulting in the gas not being cooled to the appropriate temperature and excessive cooling of the gas, causing waste of energy.
