Discussion on new explosion suppression technology with heat pipe foam composite structure

In order to quickly derive the explosion heat to restrain the heat destruction role of the explosion waves,the explosion could maximally reduce the coupling function danger of the flame and pressure wave. A new heat pipe foam composite explosion suppression structure was provided. Based on the actual calculation and the numerical simulation method,the flame arrester explosion suppression effect of the foam metal and the heat pipe composite structure was analyzed. The calculation results showed that the built-in foam iron nickel metal could make the explosion temperature reduced by 8.9% and with the phase transition mode,the built-in composite heat pipe could rapidly derive the 1.71×1012 J energy. A mathematical model of the heat pipe foam composite structure was established. The new heat pipe foam composite structure showed that within 0.095 seconds,the flame temperature could be reduced to 1 600 K.Therefore,the heat pipe foam composite structure could effectively lose the flame pressure wave. In comparison with the CH4 and CO2 concentration distribution conditions in the pipe line,the CH4 concentration at the shaft line of the pipe line in the heat pipe foam composite structure could be controlled about 4.5%. Thus the feasibility of the heat pipe foam composite structure applied to the suppression of the explosion was verified.
