Abstract
The utility model relates to a fire protection equipment in the chemical engineering technical field. The structure of the utility model is indicated in the attached figure 1. The utility model comprises a flame arrester shell, a seal cover 2 whose both ends are connected through a flange, and a flame arrester core 3 arranged in the shell. The flame arrester core is composed of multiple corrugated plate layers 4 and metal screen layers 5 which are alternately arranged and are fixed on lugs 10 on the inner wall of the shell through bolts 7 which are threaded through the flame arrester core. The alternately arranged corrugated plate layers 4 and metal screen layers 5 include respectively two to eight layers. The corrugated plates are aluminum alloy plates with triangle corrugation. The number of the bolts 7 is three and the number of the inner wall lugs 10 is three. An angle which is formed by every two inner wall lugs 10 is 60 degrees. The utility model has the advantages that the flame arrester core is composed of plates and screens which are alternately arranged, therefore the backfire carbon particles and the sparks are effectively dispersed, separated and extinguished, improving the flame arresting property; the aluminum alloy corrugated plates with the heat conductivity higher than that of the stainless steel are adopted and have good heat dissipation property, ensuring the flame arresting to be improved; and the flame arrester core is fixed by the bolt and the inner wall lug, therefore the assembly becomes convenient.
Description
Technical field: the utility model relates to chemical industry equipment, is a kind of fire equipment that is mainly used on fuel gas pipeline and the storage tank.
Background technology: but spark arrester is to stop transporting combustible gases pipeline and storage fuel vapor tank body because of the set off an explosion indispensable safety means of fire of tempering.Now still at the old-fashioned wire fabric arrester that uses, simple structure practicality, but back-fire relief poor performance mainly are applicable to normal pressure oil tank body, have been unsuitable for pressing fuel gas pipeline and storage tank, and easily stop up inconvenient disassembly, cleaning; More new-type corrugated plate dst spark arrester, the back-fire relief performance is good, but exists stainless steel wave card thermal conductivity factor little, and thermal diffusivity is relatively poor, has limited the defectives such as raising of back-fire relief performance.
Summary of the invention: technical problem to be solved in the utility model, existing wire fabric arrester and stainless steel wave card spark arrester are improved, with the two in conjunction with constituting a kind of novel expanded metals formula spark arrester, adopt aluminium alloy corrugated plating and new back-fire relief core body fixed form, make the back-fire relief performance good, be easy to disassembly, cleaning and displacement.
Structure of the present utility model as shown in Figure 1, back-fire relief core body 3 etc. constitutes in capping 2 that is connected by flange by spark arrester housing 1, its two ends and the housing, the back-fire relief core body comprises multilayer ripple flaggy 4 and metal stratum reticulare 5 alternately, is fixed on the inner walls ears or side handles of a utensil 10 by the bolt 7 that passes the back-fire relief core body.Ripple flaggy 4 alternately and metal stratum reticulare 5 respectively are the 2-8 layer; Corrugated plating is the aluminium alloy plate with triangle ripple.The bolt 7 and the inner walls ears or side handles of a utensil 10 respectively have three, each other in 60 ° of angles.
The good effect of this spark arrester is that the back-fire relief core body is that expanded metals is alternate, and wire netting can remedy the big slightly gap that occurs between corrugated plating, the expanded metals combination, more help to tempering carbon granule Mars dispersion, intercept, extinguish, effectively raise the back-fire relief performance.Adopt aluminium alloy corrugated plating thermal conductivity factor to be higher than stainless steel, thermal diffusivity is good, also favourable raising Fire retardance.By the fixing back-fire relief core body of bolt and the inner walls ears or side handles of a utensil, make mounting or dismounting convenient.
Description of drawings: accompanying drawing 1 expanded metals formula spark arrester structure chart accompanying drawing 2 expanded metals formula spark arrester housing front view accompanying drawings 3 expanded metals formula spark arrester housing left views
The specific embodiment: its structure of this spark arrester as shown in Figure 1, two flanged (FLGD) cappings 2 are connected with housing 1, back-fire relief core body 3 is installed in the housing 1, the back-fire relief core body is made of alternately 7 layers of ripple flaggy and 6 layers of metal stratum reticulare, and what is called is that one deck ripple flaggy layer of metal stratum reticulare is arranged installation alternately.Three parallel long bolts 7 each other in 60 ° of angles pass the back-fire relief core layer, are tightened up by nut 8 earlier, insert in the bolt hole of three ears or side handles of a utensil 10 of inner walls again, and are fixing by nut 9.Fire-retardant core is external core body shell 6, and there is the gland 11 with porous at the core body two ends, assemble in order to the back-fire relief core body.Spark arrester housing 1 shape shown in accompanying drawing 2,3, the cylindrical shell open at both ends, wherein its inwall of an end welds three ears or side handles of a utensil admittedly, three ears or side handles of a utensil are each other in 60 ° of angles.
Corrugated plating is the aluminium alloy plate with triangle ripple, every bed thickness 15-20mm, and ripple height (crest is to the trough height) 0.5-1mm, present embodiment is 0.6mm.Spark arrester housing 1 and two ends capping 2 can adopt Fine Steel Casting iron plate or cast steel to make, and present embodiment is a cast steel.
