Title:
BUFFER WALL-FLOW-TYPE MULTI-PORE PASSAGE FLAME ARRESTER
Document Type and Number:
WIPO Patent Application WO/2020/015022
Kind Code:
A1
Abstract:
A buffer wall flow-type multi-pore passage flame arrester, comprising a buffer flow-dividing hood (6) and a Z-shaped wall-flow-type multi-pore passage flame arresting core (7). The buffer flow-dividing hood (6) is of a round-bottom flat-opening cylindrical or hemispherical shape; small holes are distributed on the surface of a hood body; pore passages are fully distributed in the Z-shaped wall-flow-type multi-pore passage flame arresting core(7); in two adjacent pore passages, an inlet of one pore passage is blocked and an outlet of the other pore passage is blocked; in a height direction of the middle cross section of the flame arresting core (7), holes are formed in the middle wall surfaces of two adjacent pore passages; and an upper pore passage and a lower pore passage form a fluid passage. When deflagration or detonation flames occur in a gas pipeline, high-speed spreading flames and strong pressure waves firstly act on the buffer flow-dividing hood (6), so that the gas pressure at the center of the fire arresting core (7) is reduced to a certain extent and the flame spreading speed is reduced; the flames pass through the Z-shaped wall-flow-type multi-pore passage flame arresting core (7), so that the probability of collision between excited free radicals in a combustion process and the wall surfaces of the passages is greatly increased, the occurrence of flame quenching is facilitated, and thus the safety is improved.
