Description
(1) technical field
The utility model relates to fire-fighting domain, belong to allow gas by but the flame block device that do not allow flame or blast wave to pass through in particular for the flame block device in the gas pipeline, particularly is a kind of fuel gas pipeline dry type spark arrester.
(2) background technology
Present domestic gas internal-combustion engine is in the starting stage, the spark arrester that corresponding sites such as its air supply header line, by-pass line, air inlet pipeline, charge air cooler, booster, blender adopt, and majority all is the metal mesh type spark arrester.The major defect of this spark arrester is: fire-retardant core is easily stifled, not easy to clean; Back-fire relief speed is lower, generally is no more than 200m/s; Flow resistance is bigger.Therefore can not satisfy the specification requirement of gas internal-combustion engine air feed and air inlet pipeline system.By retrieval, a piece of writing surplus relevant patent documentation has ten wherein has three pieces to be applicable to gas pipeline, can be used as relevant documents of the present utility model, but its architectural feature has significant difference.
(3) summary of the invention
The purpose of this utility model just is independent development and a kind of distinguished fuel gas pipeline dry type spark arrester is provided, overcome the shortcoming and defect part of above-mentioned metal mesh type spark arrester, make its every technical indicator and performance satisfy the requirement of gas internal-combustion engine air feed and air inlet pipeline system.
Above-mentioned purpose is realized by following technical proposals:
This spark arrester comprises housing, bracing frame, fire-retardant core and connecting bolt nut four parts.It is characterized in that housing is made up of air inlet end cap, give vent to anger end cap and main body cover.Bracing frame is made up of inlet end bracing frame and outlet side bracing frame.Fire-retardant core is by a plurality of corrugated fire-retardant core assemblies superimposed composition.The air inlet end cap and the end cap of giving vent to anger are installed in the two ends of main body cover respectively, and are connected in one with some connecting bolt nuts.Inlet end bracing frame and outlet side bracing frame are clamped in the two sides of fire-retardant core, and are become one by fire-retardant core bolt and nut serial connection, are contained in the inner chamber of main body cover.
Fire-retardant core assembly in the above-mentioned fuel gas pipeline dry type spark arrester is made up of corrugated ribbon, dull and stereotyped band and assembly shell.Corrugated ribbon and flat board are with the two alternate being wrapped in the assembly shell, and its integral body is disc-shape.Constitute some triangular shaft to the extinguishing fine pore by corrugated ribbon and dull and stereotyped band.
Bracing frame in the above-mentioned fuel gas pipeline dry type spark arrester is three donut shapes, and there is a wheel hub at the center, and there is axial circular hole at the wheel hub center, and 8～16 uniform radial spokes fuse its annulus and wheel hub.
The fire-retardant core component count of this spark arrester can be according to the back-fire relief performance demands is determined.Under the fixed situation of the size of housing and bracing frame, if the fire-retardant core component count is less, can not fill up axial space, then fill up jam-packed with ring spacer.
According to the spark arrester of technique scheme processing and manufacturing, relevant position such as between the total pipeline of air supply system, gas internal-combustion engine air intake branch line, machine air inlet pipeline, charge air cooler that can be used for coal mine mash gas and other flammable explosive gas and the booster.When faults such as tempering, blast occurring, can play flame-out, explosion-proof, protect source of the gas, air supply system, gas internal-combustion engine and attached device thereof effectively.Its back-fire relief speed can reach 1400m/s, and its flow resistance is littler than metal mesh type spark arrester, and other technical indicator has also all satisfied the technology and the safety requirements of gas internal-combustion engine air feed and air inlet pipeline.And rational in infrastructure, simple compact, mounting or dismounting are convenient, and cost is lower, is easy to promote.

(5) specific embodiment
Embodiment of accompanying drawings:
In the accompanying drawing, the 1st, air inlet end cap, the 2nd, inlet end bracing frame, the 3rd, main body cover, the 4th, shell bolt and nut, the 5th, outlet side bracing frame, the 6th, the end cap of giving vent to anger, the 7th, fire-retardant core bolt and nut, the 8th, fire-retardant core, the 9th, drain screw, the 10th, corrugated ribbon, the 11st, dull and stereotyped band, the 12nd, fire-retardant core assembly shell.C is the flame expansion chamber, and D is that triangular shaft is to the extinguishing fine pore.
By shown in Figure 1, this spark arrester comprises housing, bracing frame, fire-retardant core and connecting bolt nut four parts.It is characterized in that housing is made up of air inlet end cap 1, give vent to anger end cap 6 and main body cover 3.Bracing frame is made up of inlet end bracing frame 2 and outlet side bracing frame 5.Fire-retardant core 8 is by a plurality of corrugated fire-retardant core assemblies superimposed composition.The air inlet end cap 1 and the end cap 6 of giving vent to anger are installed in the two ends of main body cover 3 respectively, and are connected in one with some connecting bolt nuts 4.Inlet end bracing frame 2 and outlet side bracing frame 5 are clamped in the two sides of fire-retardant core 8, and are become one by fire-retardant core bolt and nut 7 serial connections, are contained in the inner chamber of main body cover 3.
Shown in Fig. 1,2, the bracing frame 2,5 of this spark arrester is three donut shapes, and there is a wheel hub at the center, and there is axial circular hole at the wheel hub center, and 12 uniform radial spokes fuse its annulus and wheel hub.
Shown in Fig. 3,4, corrugated fire-retardant core 8 by corrugated ribbon 10, flat board be with 11 and assembly shell 12 form.Corrugated ribbon 10 is with 11 the two alternate being wrapped in the assembly shell 12 with flat board.Its integral body is disc-shape, is with 11 to constitute some triangular shaft to extinguishing fine pore D by corrugated ribbon 10 and flat board.
The operation principle of this spark arrester is: spark arrester is installed in the fuel gas pipeline, just pipeline section is divided into many little triangular-sections, and each triangular shaft all is alternately to be made of with 11 with dull and stereotyped the corrugated ribbon among Fig. 4 10 to fine pore D.These small triangle axial porosities provide some slypes for fuel gas.Fuel gas enters this spark arrester by the left end of Fig. 1, and some triangular shaft of process fire-retardant core 8 are gone out from its right-hand member then to fine pore D.When its right-hand member one side generation tempering or explosion time, flame is introduced into the flame expansion chamber C of the end cap 6 of giving vent to anger, and the some triangular shaft that oppositely enter fire-retardant core 8 again are to fine pore D.According to the slit quenching principle, flame just in these slypes D by extinguishing, thereby prevent that flame from along the reverse climing combustion initiation fire of pipeline, explosion accident, guaranteeing life, property and device security.
Drain screw 9 among Fig. 1 is used for discharging the ponding that the spark arrester inlet end is separated from fuel gas.
