摘要:
为了研究超声热效应对于气体解吸的影响规律，利用自行研制的具备施加超声功能的吸附解吸装置，对吸附饱和氮气的型煤试件开展超声热效应下的气体解吸试验。利用试验数据，拟合出了不同氮气压力下超声热效应作用过程中温度变化方程，解吸量方程及解吸速率方程。同时，对解吸量方程和解吸速率方程进行了试验数据验证。结果表明：超声热效应作用能够有效地提高型煤试样的温度，提高氮气的解吸130.9%～145.8%。验证结果相对误差集中在5%以内，拟合方程能够反映出超声热效应作用过程中解吸量及解吸速率的变化情况。
Abstract:
In order to study the influence law of gas desorption by ultrasonic thermal effect, through using the self-developed adsorption-desorption device with function of applying ultrasonic, the experiments on gas desorption under ultrasonic thermal effect of briquette coal sample adsorbing saturated nitrogen were conducted. The equations of temperature variation, desorption quantity and desorption rate in the process of ultrasound thermal effect under different nitrogen pressures were fitted by using the experimental data. Meanwhile, the equations of desorption quantity and desorption rate were validated by experimental data. The results showed that: the ultrasound thermal effect can improve the temperature of briquette coal system effectively, and improve the desorption of nitrogen by 130.9%-145.8%. The relative error of verification results were concentrated in less than 5%. The fitting equations can better reflect the changes of desorption quantity and desorption rate in the process of ultrasound thermal effect.
