摘    要:以燃煤烟气为研究对象,利用鼓泡反应器进行化学法吸收CO2的半连续实验研究.通过正交试验及脱除率的计算,考察了吸收剂种类、吸收剂浓度、烟气流量、烟气温度及液面高度对CO2吸收效果的影响.结果表明:氨水吸收剂的吸收效果最好,烟气温度对CO2的脱除率影响较小.选择氨水作为吸收剂进行单因素实验研究,得到了吸收剂浓度、入口处CO2浓度、烟气流量、液面高度与脱除率、吸收能力及吸收速率之间的关系.

关 键 词:鼓泡反应器  正交实验  单因素实验  二氧化碳  吸收

Abstract:In order to absorb the CO2 in coal-fired flue gas, semi-continuous experimental studies for CO2 capture using chemical method were carried out with bubbling column reactor. According to the orthogonal experiment and the calculation of the removal rate, the research focused on the effect of absorbent type, gas temperature, flow rate, CO2 content, liquid level and absorbent concentration on the CO2 absorption. The results showed that the ammonia is one of the best absorbent, and the impact of the gas temperature is minimal. The influences of ammonia concentration, liquid level, flow rate and CO2 concentration on removal rate, absorption capacity and absorption rate are obtained by single factor experiments using ammonia solution.
Keywords:bubble column reactor  orthogonal experiment  single factor experiment  carbon dioxide  absorption
