Abstract

Abstract

The Mei extinction detection system and the self-developed 20 L pulse pneumatic spray multiphase explosion test system were applied to experimentally investigate the explosion parameters of the diethyl ether mist/air mixtures. By regulating pneumatic pressure and designing spray dose, the explosion parameters of the diethyl ether mist/air mixtures with the same particle size and different mass concentrations were obtained including explosion overpressure, explosion temperature and ignition delay time. The results show that when the Sauter mean diameter of diethyl ether mist is 22.90 μm, the lower explosion limit of diethyl ether mist/air mixtures is 80.261 g/m³, the upper explosion limit is 417.34 g/m³, the highest peak overpressure is 0.78 MPa which occurs with the mass concentration as 278.23 g/m³, the highest peak temperature is 1 260 ℃ which occurs with the mass concentration as 228.29 g/m³, and the ignition delay time takes on a U-shaped distribution in the explosion limit range.
