Abstract
The utility model relates to a fire arrester which comprises a fire arrester body; the fire arrester body is supported by a support; an upper blocking mesh and a lower blocking mesh are arranged in the fire arrester body; a fire-resistant substance is filled between the upper blocking mesh and the lower blocking mesh; an air outlet is arranged on the side wall of the upper part of the fire arrester body; the air outlet is communicated with an explosion-proof device; the explosion-proof device is arranged at the upper part of the upper blocking mesh in the fire arrester body; an air inlet is arranged at the bottom of the fire arrester body; and a one-way valve clack is arranged at the air inlet. The fire arrester has the advantages that explosion accidents caused by tempering are prevented, the fire-resistant effect is good, and the use is safe and reliable.
Description
Technical field
The utility model relates to a kind of spark arrester, belongs to the spark arrester technical field.
Background technology
The conveying that spark arrester is usually used in industries such as metallurgy, chemical industry might take place on the pipeline pipe network on fire, in the prior art, the flame retardant bed structure of spark arrester has gravel type, metal mesh type or ripple type, be applicable to the fuel gas pipeline, in environment abominable chemical plant or the more cement plant of airborne dust, exist the problem of tempering, exist potential safety hazard, back-fire relief speed is slower simultaneously, the unfavorable shortcoming of effect.Therefore, need provide a kind of new technical scheme to solve above-mentioned technical problem.
The utility model content
The purpose of this utility model provides effective, the safe and reliable spark arrester of a kind of back-fire relief.
The technical solution adopted in the utility model is:
A kind of spark arrester, comprise the spark arrester body, described spark arrester body passes through stent support, be provided with backstop and following backstop in the described spark arrester body, described going up between backstop and the following backstop is filled with the back-fire relief material, and described spark arrester body upper portion side wall has the gas outlet, described gas outlet is communicated with explosion-protection equipment, described explosion-protection equipment places the intrinsic backstop top of going up of spark arrester, and described spark arrester body bottom has air inlet, and described air inlet place is provided with clapper.
Described explosion-protection equipment comprises the combustion chamber, and bottom, described combustion chamber is communicated with the spark arrester body interior, and described top of combustion chamber is provided with rupture pressure disc, described rupture pressure disc bottom coated with protective film.
Described back-fire relief material is wire packing or quartz sand.
Advantage of the present utility model: prevent the explosion accident that tempering causes, back-fire relief is effective, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, spark arrester body, 2, support, 3, the back-fire relief material, 4, clapper, 5, backstop down, 6, the gas outlet, 7, the combustion chamber, 8, air inlet, 9, rupture pressure disc, 10, diaphragm, 11, go up backstop.
The specific embodiment
As shown in Figure 1; a kind of spark arrester of the present utility model; comprise spark arrester body 1; spark arrester body 1 supports by support 2; be provided with backstop 11 and following backstop 5 in the spark arrester body 1; be filled with back-fire relief material 3 between last backstop 11 and the following backstop 5; back-fire relief material 3 is wire packing or quartz sand; spark arrester body 1 upper portion side wall has gas outlet 6; gas outlet 6 is communicated with explosion-protection equipment; explosion-protection equipment places last backstop 11 tops in the spark arrester body 1, and spark arrester body 1 bottom has air inlet 8, and air inlet 8 places are provided with clapper 4; explosion-protection equipment comprises combustion chamber 7; 7 bottoms, combustion chamber and spark arrester body 1 internal communication, 7 tops, combustion chamber are provided with rupture pressure disc 9, rupture pressure disc 9 bottom coated with protective film 10.
During work; combustion gas enters from air inlet 8; by clapper 4; backstop, back-fire relief material 3; enter people combustion chamber 7; 7 flow to gas outlet 6 from the combustion chamber again, when tempering phenomenon took place, the back flow of gas of burning entered 6 places, gas outlet; advance in people's spark arrester body 1 by combustion chamber 7; advanced back-fire relief material 3, the gas of burning is extinguished, and clapper 4 is closed because of drawing effect; the gas that refluxes produces air pressure in combustion chamber 7; bursting diaphragm 10 and rupture pressure disc 9 release pressures, the generation of the explosion accident of avoiding, safe and reliable.
