密闭环境内固体吸收剂循环净化CO2反应特性
Reaction characteristics of CO2 circulation purification by solid absorbents in closed environments
摘要
Abstract
By using a simulation device of CO2 circulation purification in a closed environment, CO2 circulation purification experi-ments were carried out with three kinds of solid chemical absorbents, LiOH, Ca( OH) 2 and soda lime. Experimental results show that all the absorbents can absorb CO2 , and there are the optimal space velocity values for the three absorbents, which are 110400, 38700, and 40500 h-1 , respectively. Under these space velocity value conditions, the reaction time is the shortest and the reaction rate is the fastest for absorbing the CO2 volume fraction of 2% to 0.03%. The relationships between reaction rate and CO2 mass concentration as well as the maximum reaction rate order of the three absorbents under experimental conditions were obtained by function fitting and mathematical analysis. Further analysis indicates that the CO2 absorption rates of the three absorbents under the optimal space velocity value conditions are able to meet the requirements of relevant standards for actual CO2 purification in closed environments, while the CO2 volume fraction would fluctuate around certain intermediate values in theory.关键词
