<p>In this research, the effects of different concentrations of ultrafine water mist containing tea polyphenols with different blockage ratios (φ) on methane explosion inhibition were investigated, by changing the concentration of tea polyphenols (TP) in ultrafine water and the blockage ratio, explosion inhibition, and flame suppression. The results showed that the explosion pressure in the pipeline gradually increased with an increase in the blockage ratio. The propagation time of the explosion flame to the end of the pipeline first increased and then decreased, and the time taken for the pressure to return to normal after the explosion was delayed. Compared with pure methane and pure ultrafine water conditions, when φ = 0 and the TP concentration is 2.5%, the explosion overpressure decreases by approximately 52.47% and 28.73% respectively.

摘要

In this research, the effects of different concentrations of ultrafine water mist containing tea polyphenols with different blockage ratios (φ) on methane explosion inhibition were investigated, by changing the concentration of tea polyphenols (TP) in ultrafine water and the blockage ratio, explosion inhibition, and flame suppression. The results showed that the explosion pressure in the pipeline gradually increased with an increase in the blockage ratio. The propagation time of the explosion flame to the end of the pipeline first increased and then decreased, and the time taken for the pressure to return to normal after the explosion was delayed. Compared with pure methane and pure ultrafine water conditions, when φ = 0 and the TP concentration is 2.5%, the explosion overpressure decreases by approximately 52.47% and 28.73% respectively. There is even a phenomenon known as quenching. This indicates that under these conditions, the explosion of methane has been effectively suppressed. This condition is the optimal inhibition effect for a methane explosion. The synergy was attributed to the combination of physical and chemical effects, which were also affected by the different additive conditions. This research provides an effective solution for suppressing methane explosions by using additives.
