摘要
自组装了动力波实验装置,对装置的复合性能、气速与压降、驻区与气液比等关系进行测定,确定了装置正常操作的条件,气速在2 264.8 ～4 917 L/h范围内,液气比在0.015 5～0.027 4之间,驻区稳定.以空气通过丙酮溶液模拟车间含丙酮空气,对装置的吸收效率进行测定.结果表明,以清水为吸收液时,低浓度丙酮吸收效率接近100％;以含丙酮水循环操作时,随溶液中丙酮浓度增高,吸收效率降低;吸收液中添加丙酮稳定剂时,随稳定剂浓度增加效果会下降,稳定剂浓度为处理液的1.36/10 000时,吸收率比清水提高12％,总效率可达86.2％.
The relation of the overall performance,gas velocity,pressure drop,the region and vapour-liquid ratio was measured with self-made dynawave experimental apparatus to determine the normal operating conditions.When the gas velocity was in the range of 2 264.8 L/h to 4 917 L/h and the liquid-gas ratio 0.015 5 ～ 0.027 4,the region is stable.To measure the absorption efficiency of the device,air through acetone was used to stimulate the air containing acetone in the workshop.The results showed that when water was used as absorbent,the efficiency of absorption was close to 100％ ;when acetone-containing water was used in loop operation,the absorption efficiency decreased with the increase of acetone concentration in the solution;when stabilizer was added in the absorption liquid,the efficiency dropped when the concentration of the stabilizer increased and the overall efficiency of 86.2％,12％ higher than when the pure water was used,could be achieved when the concentration of the stabilizer was 1.36/10 000 of that of the conditioning fluid.
