Description
Technical field
The present invention relates to a kind of modularization concave flame-retardant device, in particular to a kind of resistance of Class A combustible gas deflagrating flame
Burner.
Background technique
Flame-retardant device is a kind of industrial widely applied safety equipment, pipe-line system, oil gas for transporting combustible gases
The fields such as recovery system and fuel gas exhaust system, to avoid explosion accident.Such as shipbuilding industry, ship is continuous for a long time
Work, leads to each component hot-spot in diesel engine crankcase, the heat of generation make particle in crankcase from lubricating oil and
The gas leakage of piston ring forms extremely incendive mist of oil mixed gas.When mist of oil gaseous mixture reaches a certain concentration and temperature reaches and draws
When the temperature of quick-fried gaseous mixture, just cause crankcase explosion.Crankcase explosion is very easy to lead to ship fire.Once ship occurs
Fire, caused by casualties, Vessel And Cargo etc. direct economic loss, and manpower, material resources and financial resources, the waters of rescue investment
Pollution, shipwreck occupy the indirect economic loss such as navigation channel and harbour, all very huge.Therefore, Association International Des Registres have issued new rule
IACS UR M66 is clearly stipulate that from July 1st, 2008, the diesel engine explosion-proof valve that is mounted on new boatbuilding, it is necessary to fire-retardant
Structure, it is ensured that do not occur combustion case outside flame-retardant device.China Classification Society (CCS) enter at grade construction also 2008 total
It is clear in No. 038 circular, IACS UR M66 file will be used.
The industries such as petroleum, coal mine and chemistry generally use ripple type, tubular type, slit-type fire arrester prevent burning and it is quick-fried
It is fried.Then, in above-mentioned flame-retardant device, flame requires to propagate very long a distance, could extinguishing and knock down the flame, so as to cause
The problems such as flame low efficiency that fire arrester is bulky, extinguishing is gone out.
Summary of the invention
The purpose of the present invention is for solve the common flame-retardant device of industries such as petroleum, coal mine and chemistry there are it is bulky, quench
The problem of extinguishing flame low efficiency, proposing a kind of compact-sized, extinguishing to go out, flame is high-efficient, performance is stable, modularized design and is convenient for
The modularization concave flame-retardant device of maintenance.
In order to achieve the above object, the technical scheme is that
A kind of modularization concave flame-retardant device, the single 3 D being formed by stacking including more than one by two panels flame-resistant sheet are fire-retardant logical
Road is provided with turbulence columns on the flame-resistant sheet, and the turbulence columns include windward side and leeward;The turbulence columns
Windward side be concave structure or the turbulence columns leeward be concave structure or the turbulence columns windward side,
Leeward is concave structure;Before gap of the previous row's turbulence columns between the two neighboring turbulence columns of latter row
Fang Zhongxin, and the gap of the two neighboring turbulence columns of latter row is less than the width of the turbulence columns of the previous row.
The concave structure uses one of triangle indent, trapezoidal indent, arc concave shape.
Gap between the two neighboring turbulence columns is the runner of deflagration flame.
Along turbulence columns installation direction being superimposed installation in the same direction between the flame-resistant sheet and flame-resistant sheet, to obtain single 3 D fire-retardant
Channel.
Along turbulence columns installation direction, opposite superposition installation obtains single 3 D two-by-two between the flame-resistant sheet and flame-resistant sheet
Fire-retardant channel.
The beneficial effects of the present invention are:
1) the concave structure of turbulence columns windward side, increases the heat transfer area of turbulence columns windward side;Meanwhile concave structure is prolonged
That has grown air-flow flows through path, reduces the speed of air-flow near turbulence columns windward side, extends air-flow and turbulence columns windward side
Heat transfer time accelerate flame quenching to improve the heat transfer property of deflagration flame and turbulence columns windward side.
2) the concave structure of turbulence columns leeward increases the heat transfer area that turbulence columns meet leeward;Meanwhile leeward
Concave structure, make leeward region there are negative pressuren zone, air-flow low speed made to flow back, vortex is formed, to reduce turbulence columns
The speed of leeward air-flow extends the heat transfer time of air-flow Yu turbulence columns leeward, finally improves deflagration flame and flow-disturbing
The heat transfer property of column windward side, accelerates flame quenching.
It 3), can concave structure be set simultaneously by windward side or leeward or two faces according to the difference of specifically used environment
Meter, concave structure may be designed as triangle indent or trapezoidal indent or arc concave shape, and combining form is varied, so as to
To meet the requirement of different operating conditions, enhance applicability.
To sum up a kind of modularization concave flame-retardant device of the invention goes out with compact-sized, extinguishing, and flame is high-efficient, performance is steady
Calmly, the characteristics of modularized design.
