摘要:
为研究乙炔气体的分解爆炸参数，以电石法制备的乙炔为对象，采用20 L圆柱形爆炸罐，以熔断丝（20 J）作为点火源，通过实验研究了初始温度、初始压力对乙炔分解爆炸相关参数的影响规律。结果表明：初始压力为0.095~0.200 MPa时，乙炔最大分解爆炸压力及最大分解爆炸压力上升速率随初始压力的增大而增大，且初始压力超过0.140 MPa后，增幅变大；初始温度在40~80 ℃范围内，乙炔临界分解爆炸压力、最大分解爆炸压力及最大分解爆炸压力上升速率随初始温度的升高而减小。
Abstract:
In order to study decomposition explosion parameters of acetylene gas, the acetylene gas produced by industrial calcium carbide method was taken as the research object, a 20 L cylindrical tank was used as the explosion vessel, and the fusing wire (20 J) was used as the ignition source. Effects of initial temperature and initial pressure on the relevant decomposing explosion properties of acetylene gas were studied by experiments. The results show that when the initial pressure is in the range of 0.095-0.200 MPa, the maximum decomposition explosion pressure and the maximum rise rate of decomposition explosion pressure increase with the increase of initial pressure, and when initial pressure exceeds 0.140 MPa, the rise amplitude of the curve becomes larger. Critical decomposition explosion pressure, the maximum decomposition explosion pressure, and the rising rate of the maximum decomposition explosion pressure of acetylene decrease with the increase of initial temperature under the initial temperature changing from 40 ℃ to 80 ℃
