Abstract

A flame arrester structure, comprising: a housing (1) provided with a pressure relief intake end (11), a pressure relief exhaust end (12) and a chamber (13) connecting the pressure relief intake end and the pressure relief exhaust end; a fire resistant structure arranged at the pressure relief exhaust end, the fire resistant structure comprising a plurality of fire resistant layers (2) successively arranged at intervals in the axial direction of the pressure relief exhaust end; and a flow guide structure arranged inside the housing, located upstream of the fire resistant structure in the flowing direction of a pressure relief airflow inside the housing, and used for dividing the pressure relief airflow inside the housing into multiple regional airflows that flow towards different regions of the fire resistant structure. When accidents such as fire occur in pressure relief positions of storage tanks of petrochemical devices, the flame arrester structure can provide long-duration fire resistance protection, thus preventing the accidents from further escalating and allowing more readiness time for emergency rescue.
