In this paper, the three-dimensional numerical flow filed simulation of the plate and the corrugate flame arrester of explosion-proof diesel engine is carried out by FLUENT. The three-dimensional flow field distribution of two kinds of flame arrester temperature, pressure and turbulent kinetic energy are obtained. The results show that the flame arrester slit size is bigger, the free area rate higher, explosion-proof performance worse; flame quenching distance and propagation rate were positively correlated; the pressure loss of the flat plate type arrester bigge than corrugated type flame arrester, but explosion-proof ability opposite. Second is the shift and conflicting. The selection of different forms of fire resistance depends on the specific circumstances.
