Abstract: The influence of the temperature of durene solution, the height from airway nozzle to liquid level, the temperature and feed rate of air on the vapor phase concentration of durene were studied with the self-made adjustor. As a result, the temperature of the durene solution and the feed rate of air had a greater influence on the vapor phase concentration of durene, whilethe influence of the height from airway nozzle to liquid level and the feed air temperature on the vapor phase concentration was small. The vapor phase concentration of durene could be adjusted by the self-made adjustor.

摘要： 利用自制的高熔点物料气相浓度调控仪，研究了均四甲苯溶液的温度、导气管管口距离均四甲苯液面的高度、空气进气温度和进料量等对均四甲苯气相浓度的影响。实验结果表明：均四甲苯溶液的温度、空气进料量对均四甲苯气相浓度影响较大，而导入管距离液面的高度和空气温度影响较小。自制的高熔点物料气相浓度调控仪能很好地调控气相中均四甲苯的浓度，具有推广应用价值。
