Problems solved by technology

[0003] The large-diameter flame arrester used in the existing flammable gas delivery pipeline, in the process of working, due to the large diameter, the flow rate generated during the gas delivery process is large, resulting in relatively low resistance to the gas produced by the fire-retardant filter element. Large, this will speed up the damage of the fire arrester filter element, increase the maintenance cost, and reduce the service life of the large diameter flame arrester, which is not conducive to the long-term working and use of the large diameter flame arrester

Abstract

The invention discloses a flow-disperse low-pressure-drop large-diameter fire arrester which comprises an upper shell and a lower shell, wherein the upper shell is located right above the lower shell;multiple installation holes are disposed at an equal interval on circumferences of the upper shell and the lower shell; an air inlet is formed in the upper side of the upper shell; a gas outlet is formed in the lower side of the lower shell body; threaded spiral-connection holes are formed inside the gas inlet and the gas outlet; shunt mechanisms used for flow rate dispersion are disposed in twothreaded spiral-connection holes; and an upper shell connecting flange is fixedly connected to the lower side of the upper shell. The fire arrester disclosed by the invention has the beneficial effects that structural design is rational; flow rates are dispersed through flow rate dispersion, so resistance is reduced; the service life is effectively prolonged; repair fees are reduced; and normal work of the fire arrester is promoted, so spreading of flame of inflammable gas and inflammable liquid steam can be prevented more effectively and thus occurrence of backfire accidents can be prevented.

Description

technical field [0001] The invention relates to the technical field of large-diameter flame arresters, in particular to a flow-distributed low-pressure-drop large-diameter flame arrester. Background technique [0002] Flame arresters are safety devices used to prevent the spread of flames of flammable gases and flammable liquid vapors. It is generally installed in the pipeline for conveying combustible gas, or on the ventilated tank to prevent the propagation of flame (deflagration or detonation) from passing through. [0003] The large-diameter flame arrester used in the existing flammable gas delivery pipeline, in the process of working, due to the large diameter, the flow rate generated during the gas delivery process is large, resulting in relatively low resistance to the gas produced by the fire-retardant filter element. This will speed up the damage of the fire arrester filter element, increase the maintenance cost, and reduce the service life of the large diameter fl...
