摘要/Abstract

摘要： 为给甘薯粉尘爆炸预防提供依据,用20 L球形爆炸装置进行爆炸试验,研究甘薯粉尘粒径、质量浓度和点火能量3个单因素对爆炸的影响;同时,用响应面方法,通过Design-Expert 软件中Box-Behnken试验设计,对影响甘薯粉尘爆炸的因素进行对比分析。试验结果表明,甘薯粉尘最大爆炸压力随粉尘粒径的减小而增大,随粉尘浓度的增加呈现先增加后减小的趋势,随点火能量的增大而增大。同时,由Box-Behnken试验中响应面回归方程知,甘薯粉尘质量浓度对粉尘爆炸影响最大,其次是点火能量,甘薯粉尘粒径对相应粉尘爆炸影响最小。

关键词: 甘薯粉尘, 球形爆炸装置, 粒径, 质量浓度, 点火能量, 响应面方法

Abstract: To provide a sound basis for sweet potato dust explosion prevention, experiments were carried out by using a 20 L spherical explosive device. Effects of three single factors including the particle size, concentration of dust and ignition energy on the explosion were studied. Besides, the response surface methodology was used to analyze the factors influencing the explosion of sweet potato dust by Design-Expert software,based on Box-Behnken design. The results show that there is a negative correlation between the maximum explosion pressure of sweet potato dust and the particle size, that the maximum explosion pressure increases first and then decreases with the dust concentration, and that the maximum explosion pressure increases with the ignition energy. The Box-Behnken test results show that the effect of sweet potato dust concentration on dust explosion is the greatest, followed by the ignition energy, and the effect of sweet potato dust particle size on the corresponding dust explosion is minimal.

Key words: sweet potato dust, spherical explosive device, particle size, mass concentration, ignition energy, response surface methodology
