  • In order to solve the safety problem caused by flammable gas explosion in pipeline transportation, an experimental system for premixed gas explosion and explosion suppression in multiple pipelines was self-built. And then a series of premixed methane-air explosion and explosion suppression experiments were carried out under the ultrafine water mists without or with three kinds of salts in the different working conditions including the different salt mass fractions and the different mist fluxes. In the experiments, the methane volume fraction in the premixed methane-air mixture was 9.5%, and three salts used as additives were NaCl, NaHCO3 and MgCl2. According to the theories of fire science and explosion science, the different changes in the explosion characteristics were explored involving the oscillation curves and the maximum peak values of explosion overpressure, the front positions and the average propagation velocities of the explosion flame, the evolution images of the flame structure in pipe B. The results show that with the increases of salt mass fractions and ultrafine water mist fluxes with salts (NaCl, NaHCO3 and MgCl2), the maximum peaks of explosion overpressure decreased by different amplitudes compared with those under the action of pure water mist, the oscillation curves of explosion overpressure increased slowly, and the average propagation velocities of explosion flame decreased significantly. The explosion flame fronts receded different times in the pipe B. And the times when the explosion flames reached the terminal end of the pipe B delayed obviously compared with those with or without the pure ultrafine water mist. Comparisons display that the ultrafine water mist containing NaCl is superior to the ones containing MgCl2 and NaHCO3, respectively, in weakening the explosion overpressure, delaying the advance of the flame front position, decreasing the average flame propagation velocity, and reducing the receding times of the explosion flame front. The primary reason is that the ability of the anion Clto destroy OH· and H· radicals in chain explosion reactions is stronger than that of the anion HCO3 and the ability of the cation Na+ to destroy OH· and H· radicals in explosion reactions is stronger than that of the cation Mg2+.
