Description

Exempt from spark arrester of washing formula

Technical Field

The invention relates to the technical field of flame arresters, in particular to a cleaning-free flame arrester.

Background

The flame arrester is a safety device for preventing the flame spread of flammable gas and flammable liquid steam, generally installed in the pipeline for conveying flammable gas, or on the ventilated tank, the device for preventing the flame (deflagration or detonation) from passing through, and is composed of a flame arrester core, a flame arrester casing and accessories, the flame arrester is also commonly used on the pipeline for conveying flammable gas, if flammable gas is ignited, the gas flame can be spread to the whole pipe network, in order to prevent the danger, the flame arrester is also adopted, the flame arrester can also be used on the pipeline with open fire equipment to prevent the accident of non-return fire, but it can not prevent the open fire of flammable gas and liquid which are open to burn, the flame arrester is mainly composed of a shell and a filter core, the shell has enough strength to bear the impact pressure generated by explosion, the filter core is the main component for preventing the flame from spreading, the flame passes through a tiny channel of the fire retardant element and is cooled in the channel. When the flame is divided to a small degree, the heat removed through the passageway is sufficient to lower the temperature below the ignition point of the combustible material, causing the flame to extinguish. Or explained by the wall effect, when the channel is narrow to a certain extent, the collision of free radicals with the pipe wall is dominant, the free radicals are greatly reduced, the combustion reaction cannot be continued, and the flame arrester is mainly applied to the following environments or systems: a pipeline for conveying combustible gas; a flare system; an oil gas recovery system; a pipe network of heating furnace fuel gas; a gas purification and gasification system; a gas analysis system; a coal mine gas discharge system; flammable and explosive solvent systems (such as reaction kettles, storage tank vents and the like).

Regarding the working principle of flame arresters, there are mainly two views: one is based on heat transfer; firstly based on the wall effect, current spark arrester is after working a period, and tiny through-hole on its inside back-fire relief component is blockked up by oil smoke impurity etc. that carries in flame very easily, consequently need often unpick and wash, but because the spark arrester dismouting is comparatively troublesome, greatly increased workman's intensity of labour, reduced the practicality.
