Abstract
The present invention discloses a drawer-type flame arrester which comprises a housing. The housing is composed of an upper flange and a lower flange, and a flame-arresting cavity is disposed between the upper flange and the lower flange; a gland is disposed outside the flame-arresting cavity; an air inlet is disposed on the upper flange, while an air outlet is disposed on the lower flange; an anti-blast film is disposed at the air inlet; the flame-arresting cavity is provided with interlayer filling materials; gravel is disposed above the interlayer filling materials in the flame-arresting cavity; a flame-arresting core is disposed below the interlayer filling materials in the flame-arresting cavity; the flame-arresting core is enclosed by a steel wire mesh and is fixed in the flame-arresting cavity. The invention has the following advantages that: the interlayer filling materials are disposed in the flame-arresting cavity, which are not easy to deform by impact of high- pressure air flow in a pipeline, have good stability, can protect the flame-arresting core, and have good flame-arresting performance; when flame-arresting elements are maintained and replaced, the flame-arresting elements can be taken out only by removing a fastener; and the flame arrester of the invention realizes operations ofon-line cleaning, replacement, and the like.
Description
Technical field
The present invention relates to a kind of spark arrester, relate in particular to a kind of drawer type spark arrester.
Background technology
Spark arrester is that a kind of external flame that prevents is scurried into the equipment that there is flammable explosive gas or the element of pipeline, utilize wavy metal dish slit gap flame to be had the extinguishing action principle manufactures and designs, spark arrester is connected with pipeline by flange, must remove whole spark arrester from pipeline when changing the back-fire relief element.Therefore, need provide a kind of new technology to solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide that a kind of back-fire relief performance is good, the drawer type spark arrester of easy accessibility.
The technical solution used in the present invention is:
The drawer type spark arrester, comprise housing, described housing is made of upper and lower flange, be provided with the back-fire relief cavity between the described upper and lower flange, described back-fire relief cavity is provided with gland outward, have air inlet on the described upper flange, have the gas outlet on the described lower flange, described air inlet place is provided with rupture pressure disc, be provided with the interlayer filler in the described back-fire relief cavity, be furnished with gravel in the back-fire relief cavity of described interlayer filler top, be furnished with fire-retardant core in the back-fire relief cavity of described interlayer filler below, described fire-retardant core is surrounded by steel wire and is fixed in the back-fire relief cavity.
Described gland is fixed on the back-fire relief cavity by securing member.
Described back-fire relief cavity is provided with safety net outward.
Described steel wire surrounds is shaped as cone.
Advantage of the present invention is: is provided with the interlayer filler in the back-fire relief cavity, is difficult for by pipeline inner high voltage gas shock distortion, and good stability, the protection fire-retardant core, the back-fire relief performance is good; When the back-fire relief element was changed in maintenance, only need pull down securing member just can take out the back-fire relief element, realized work such as on-line cleaning, replacing.
