The novel gas pipeline flame arrester of the utility model is characterized in that the fire resistant layer which comprises the metallic fiber fabric or the metical fiber sintered felt is arranged on the cross section of the gas channel in the shell body, the metallic fiber fabric or the metical fiber sintered felt does not affect the flowing direction of the gas transmission, the metallic fiber fabric or the metical fiber sintered felt has good fire resistant performance and the heat absorbing performance, when temper generated from the combustion of gas or flame caused by the other reasons passes through the fire resistant layer, the metallic fiber fabric or the metical fiber sintered felt rapidly cool high-temperature gas to the extinguishing temperature of the flame, enables the flame to be automatically distinguished, improves thesafety of the gas transmission of a gas pipe network, and the whole flame arrester has simple structure and lower cost.
Description
Technical field
The utility model relates to a kind of spark arrester, relates in particular to a kind of colliery that is mainly used in and carries on the gas tube, also can be used for the novel gas tube spark arrester on other fuel gas conveyance conduits.
Background technology
At present, the gas of mine extraction adopts pipeline to carry mostly, the output of pipeline connects the user, gas in the pipeline easy firing that is heated produces blast, promptly there is certain potential safety hazard, cross the low concentration gas of low and entrained air especially for the gas pressure of carrying, the gas combustion of output exists the probability of tempering bigger.The flame that the tempering that produces for the gas combustion that prevents to export or other reason cause is propagated in gas tube, and the generation of gas combustion explosion is provided with spark arrester usually in the prevention pipeline in pipeline.Now still at the old-fashioned wire fabric arrester that uses, though the simple structure practicality, the back-fire relief poor performance; More new-type corrugated plate dst spark arrester, the back-fire relief performance is good, but stainless steel wave card thermal conductivity factor is little, and thermal diffusivity is relatively poor, has limited the raising of back-fire relief performance.
Therefore, need a kind of novel gas tube spark arrester of development, spark arrester neither changes the flow direction of combustion gas, in the time of making flame that tempering that gas combustion produces or other reason cause through spark arrester again fire is extinguished rapidly, improve the gas pipe network and carry the security and the reliability of gas, and claimed structure is simple, easy to manufacture, cost is lower.
The utility model content
In view of this, the utility model proposes a kind of novel gas tube spark arrester, spark arrester adopts metal fibre interlacement or metallic fiber sintered felt as flame retardant bed, utilize metal fibre interlacement or metallic fiber sintered felt labyrinth type pore structure and metallic fiber good heat insulation, heat conductivility, both improved the back-fire relief performance of spark arrester, the flame that the generation tempering of gas fuel gas buring or other reason are caused can extinguish fire rapidly when passing through spark arrester, security and reliability that the gas pipe network is carried gas have been improved, and simple in structure, easy to manufacture, cost is lower.
A kind of novel gas tube spark arrester that the utility model provides, comprise housing, described housing is provided with gas import and gas export, also comprises being arranged on the flame retardant bed on the gas channel cross section in the housing, and described flame retardant bed is made up of metal fibre interlacement or metallic fiber sintered felt.
Further, also comprise the gripper shoe that is fixedly installed in the housing, the air-flow through hole is set on the gripper shoe, flame retardant bed is fixedly installed on the two sides of gripper shoe;
Further, to the diminishing reducer pipe of two ends diameter, flame retardant bed was arranged on the cross section of reducer pipe interlude in the middle of described housing was served as reasons;
Further, described housing comprises short circuit I and short circuit II, and short circuit I is provided with flange I, and short circuit II is provided with flange II, and described flame retardant bed is arranged between the end face of the end face of short circuit I and short circuit II, and fixedlys connected with short circuit II with short circuit I with flange II by flange I;
Further, described gripper shoe is an air distribution plate.
The beneficial effects of the utility model are: the gas tube spark arrester of the utility model structure, the flame retardant bed of being made up of metal fibre interlacement or metallic fiber sintered felt is set on the cross section of gas tube in the housing, metal fibre interlacement or metallic fiber sintered felt neither influence the flow direction that gas is carried, and metal fibre interlacement or metallic fiber sintered felt have good back-fire relief performance and heat absorption capacity, when the flame that the tempering that gas combustion produces or other reason cause passes through flame retardant bed, metal fibre interlacement or metallic fiber sintered felt are cooled to the fray-out of flame temperature rapidly with high-temperature gas, flame is extinguished automatically, improved the security that the gas pipe network is carried gas, and whole spark arrester is simple in structure, manufacturing cost is lower.
Description of drawings
Following structure the drawings and specific embodiments are described in further detail the utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of gripper shoe.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, Fig. 2 is the structural representation of gripper shoe, as shown in the figure: a kind of novel gas tube spark arrester comprises the housing 3 with gas import and gas export, flame retardant bed 1 and have the gripper shoe 2 of a plurality of air-flow through holes 10 on it, described flame retardant bed 1 is made up of metal fibre interlacement or metallic fiber sintered felt, the housing 3 of present embodiment is served as reasons middle to the diminishing reducer pipe of two ends diameter, described reducer pipe is made up of short circuit I8 and short circuit II9, short circuit I8 is provided with flange I4, short circuit II9 is provided with flange II7, flame retardant bed 1 is fixedly installed on the two sides of gripper shoe 2, gripper shoe 2 is clamped between flange I4 and the flange II7, gripper shoe 2 is provided with gasket seal 5 with the contact position of flange I4 and flange II7, in the bolt hole of flange I4 and flange II7, penetrate bolt, screw nut, clamp gripper shoe 2, the other end of short circuit I8 and short circuit II9 is provided with 6, two flanges 6 of flange respectively and is connected with the gas tube of carrying.
In the present embodiment, gripper shoe 2 adopts air distribution plate, and the air distribution plate two sides are concave inward structure, and metal fibre interlacement or metallic fiber sintered felt are embedded in the air distribution plate both sides and are in the groove of concave inward structure, and periphery is fixed by spot welding.
Device of the present utility model generally is installed near user's use side.Though flame retardant bed 1 and air distribution plate have certain influence to the gas flow rate that passes through, reducer pipe interlude diameter is big, and air-flow through hole 10 is more, can't influence the flow of gas.When the flame that the tempering that gas combustion produces or other reason cause passes through flame retardant bed 1, metal fibre interlacement or metallic fiber sintered felt are cooled to the fray-out of flame temperature rapidly with high-temperature gas, flame is extinguished automatically, improved the security of gas pipe network delivery of fuel gas.
