Abstract
The utility model relates to a pipeline fire blocking apparatus. Each fire blocking apparatus adopts 4-6 layers of stainless steel corrugation fire blocking layers of which the corrugations are triangles of which the height has certain dimensions. Fire blocking layers are arranged in a case body of the fire blocking apparatus, and both ends of the fire blocking apparatus are connected with the case body by cone-shaped covers with flanges to form a pipeline fire blocking apparatus which has a compact structure and can bear the pressure of 2.5 MPa. The pipeline fire blocking apparatus has excellent fire blocking performance, can block the backfire of high-speed flame, ensures the safeproduction of a pipeline for conveying fuel gas and the connecting device of the pipeline, and is convenient to clean and replace. The pipeline fire blocking apparatus is suitable for petrochemical plants, gas fields, city gas systems and other industrial customers having fuel gas pipelines.
Description
The utility model belongs to the fire safety equipment on the transporting combustible gases pipeline.
Flame arrester for pipe can be when the pipeline conveying has the fuel gas of pressure, the blast that prevention causes because of fuel gas tempering in the pipeline, preventing that pipeline and connection device thereof from destroying and fire takes place, all is indispensable safety means for petrochemical plant, oil gas field, town gas system and other industrial users with fuel gas pipeline.Existing domestic flame arrester for pipe still adopts the Vintage Product of the fifties, i.e. wire fabric arrester.Its flame retardant bed is by 10～14 layers, and 16～42 order copper mesh are formed.The wire netting flame retardant bed is former to be used on the oil tank, proves after tested, and its back-fire relief performance does not reach the requirement of standard GB 5908-86 regulation, thereby more can not use as flame arrester for pipe on the fuel gas pipeline.
Foreign patent DS1708116, DT2436206 and SU632365 etc. adopt the fill-type spark arrester, and volume is big, and flow resistance is big, and dismounting is complicated, cleans trouble.
The Chinese patent GG87204838 " novel ripple flame arrester for petroleum tank " of the court's application then is only applicable to the normal pressure petroleum storage tank, and not being suitable for has the fuel gas of pressure pipeline.
The purpose of this utility model is to design a kind of spark arrester that is applicable to the fuel gas pipeline of pressure, makes its back-fire relief performance reach the instructions for use of present reality, can bear the pressure of 2.5MPa, and volume is little, is easy to clean, displacement.
The structure of this flame arrester for pipe such as Fig. 1 are made up of two flanged (FLGD) conical lids (1), spark arrester housing (2) and ripple flame retardant bed (3) etc.Each spark arrester adopts 4～6 layers of stainless steel ripple flame retardant bed, and ripple is that height is 0.45～0.61 millimeter a triangle.Flame retardant bed places in the spark arrester housing, and is fixing with a centre bolt (5), separates with explosion-proof ring (4) between the flame retardant bed, and two ends are connected with housing by flanged (FLGD) conical lid (1), and it is tight to form a structure, can bear the flame arrester for pipe of 2.5MPa pressure.
The structure of spark arrester housing such as Fig. 2, an end face is for uncovered fully, and another end face has the circular hole of placement centre bolt (5).The material of spark arrester housing is a cast steel, can bear inflammable gas and cause the pressure that detonation produces because of tempering.
16～25 millimeters of the every bed thickness of ripple flame retardant bed adopt the centre bolt of M8 to fix between the flame retardant bed.
The advantage of this flame arrester for pipe is, owing to adopted the flame retardant bed of said structure, can stop the tempering of high-speed flame, guarantees the safety in production of fuel gas pipeline and connection device thereof.Experimental prototype to this flame arrester for pipe has carried out the back-fire relief performance test, and result of the test shows: when the back fire flame spread speed reached 2000 meter per seconds, this flame arrester for pipe can both stop the flame propagation of tempering at every turn under the situation of continuous tempering 10 times.Spark arrester housing result of hydraulic test shows: can bear the pressure that is not less than 2.5MPa, leakage, slight crack and permanent deformation do not appear in housing.
Since adopt this in the spark arrester enclosure interior with the fixing flame retardant bed of centre bolt, with flanged (FLGD) conical lid and the close-connected structure of spark arrester housing, can not only satisfy higher pressure requirement with bolt, volume is little simultaneously, is convenient to dismounting, cleans and replaces.
Claims (5)
1, a kind of flame arrester for pipe, form by two flanged (FLGD) conical lids (1), spark arrester housing (2) and ripple flame retardant bed (3) etc., it is characterized in that each spark arrester adopts 4～6 layers of stainless steel ripple flame retardant bed, ripple is that height is 0.45～0.61 millimeter a triangle, flame retardant bed places in the spark arrester housing, fixing with a centre bolt (5), separate with explosion-proof ring (4) between the flame retardant bed, two ends are connected with housing by flanged (FLGD) conical lid (1), it is tight to form a structure, can bear the flame arrester for pipe of 2.5MPa pressure.
