Abstract

The invention discloses a modular internal concave type flame retardant device. The modular internal concave type flame retardant device comprises more than one single three-dimensional flame retardant channel formed by overlapping two flame retardant pieces, flow turbulent columns are arranged on the flame retardant pieces, and the flow turbulent columns comprise windward sides and lee sides; thewindward sides of the flow turbulent columns are of an internal concave type structure, or the lee sides of the flow turbulent columns are of an internal concave type structure, or the windward sidesand the lee sides of the flow turbulent columns are of an internal concave type structure; and the flow turbulent columns at the front raw are located at front center of a gap of the two adjacent flow turbulent columns at the rear row, and the gap of the two adjacent flow turbulent columns at the rear row is smaller than the width of the flow turbulent columns at the front raw. The modular internal concave type flame retardant device has compact structure, high quenching and out-flame efficiency, stable performance, modular design and convenient maintenance.

Description

technical field [0001] The invention relates to a modular concave flame retardant, in particular to a flame retardant for the deflagration flame of Class A combustible gas. Background technique [0002] Flame retardant is a kind of safety equipment widely used in industry. It is used in the pipeline system for conveying combustible gas, oil vapor recovery system and combustible gas discharge system to avoid explosion accidents. For example, in the shipbuilding industry, the long-term continuous operation of the ship will cause local overheating of the parts in the crankcase of the diesel engine, and the heat generated will cause the particles from the lubricating oil in the crankcase and the leakage of the piston ring to form a highly flammable oil mist mixture. When the oil mist mixture reaches a certain concentration and the temperature reaches the temperature to detonate the mixture, the crankcase explosion will be caused. A crankcase explosion can easily lead to a ship ...
