Description
Technical field
The utility model relates to a kind of extinguishing device.
Background technology
Because the great harmfulness of transformer fire accident, the countries concerned's fire protection rule clearly stipulates, but but but but the separate unit capacity be attached to the indoor fuel oil oil immersed power transformer of civil buildings fixed extinguishing system all should be set at 40MVA and above industrial enterprise's fuel oil oil immersed power transformer, part at 90MVA and above power plant's fuel oil oil immersed power transformer, separate unit capacity at 125MVA and above independent electric substation fuel oil oil immersed power transformer, separate unit capacity.
At present, the fixed extinguishing system that is used for the outdoor large transformer is a water spray fire extinguish system.The water spray fire extinguish system of transformer has all obtained extensive use at present in power plant and electric substation's outdoor large transformer fire-fighting.Its extinguishing mechanism mainly is to produce tiny water smoke by high pressure to drip effects such as being directly injected to the material surface that is burning produces surface cool, suffocates, emulsification, dilution, vaporific water droplet from the waterfog head ejection, particle diameter is tiny, surface area is very big, meet the vaporization rapidly of fire back, take away a large amount of heats, the burning surface temperature is dropped to rapidly below the burning-point, make burner body reach the cooling purpose; After spray water is ejected into combustion zone chance heat vaporization, form the water vapour bigger 1700 times than original volume, surround and cover around the flame, because of the oxygen concentration around the burner body reduces, burning is extinguished because of anoxic; For water-fast flammable liquid, spray water impacts liquid surface and mixes with it, forms non-flame properties emulsion liquid layer, thereby burning is interrupted; For the water-soluble liquid fire, because spray water can be fine fused with water-soluble liquid, incendivity concentration is reduced, reduce burning velocity and extinguish.Mainly form by water source, supply equipment, water supply line, drench valve group, filter and water spray shower nozzle.The water spray shower nozzle generally can be divided into middling speed water spray shower nozzle and high speed water spraying nozzle.Water spray fire extinguish system then should have automatic control, manually control and meet an urgent need control three kinds of Starting mode.The water spray fire extinguish system technology is comparatively ripe, and the fire-fighting efficiency height at home and abroad all has comparatively widely and uses.But its system complex, not only comprise complete units such as drench valve group, pipeline and support, atomizer, detector and interlock control panel, also need to be provided with supporting fire supply systems such as pond, water pump, pipe network, floor space is big, the cost height, the regular maintenance management is cumbersome.And connecting line is the wet type pipeline, and fire extinguishing system need regularly be tried spray, can not be applicable to that lack of water and cold district use.
The utility model content
The utility model is in order to overcome weak point of the prior art, a kind of compact conformation to be provided, and cost is low, installation, use, fire extinguishing system easy to maintenance.
The utility model is achieved through the following technical solutions:
A kind of extinguishing device, it is characterized in that, comprise the fluid reservoir of the mixing material that extinguishing chemical and water are housed, described fluid reservoir is connected with at least one group of spray system by pipeline, nitrogen starts bottle and is connected with the nitrogen power source with gas pipeline by control valve, and described nitrogen power source is connected with fluid reservoir.
Connecting pipe between described nitrogen power source and the fluid reservoir is provided with pressure-reducing valve.
Described nitrogen power source is provided with a bottle container value.
Described spray system is connected to form successively by sectioning valve, conveyance conduit and a plurality of shower nozzle, is connected with atmospheric valve on the described conveyance conduit.
Conveyance conduit between described sectioning valve and the shower nozzle is the dry type pipeline.
Described shower nozzle is a waterfog head.
Pipeline between fluid reservoir and the spray system is the wet type pipeline.
On fluid reservoir, be connected with Pressure gauge and safety relief valve respectively.
Control valve, pressure-reducing valve, a bottle container value, sectioning valve, atmospheric valve, Pressure gauge are connected with the control module of detection control system respectively with safety relief valve.
The utlity model has following technique effect:
1. the extinguishing chemical in the extinguishing device of the present utility model need not established devices such as fire pump with the high pressure nitrogen source that is used as power.Whole system is simple in structure, arranges compactness, and control easily, and is easy to maintenance.
2. be stored in the fluid reservoir owing to extinguishing chemical, the pipeline of fire extinguishing system is a dry pipe, fire extinguishing system does not need examination spray regularly like this, can also in lack of water and cold district, use, special-purpose confession, drainage equipment needn't be set, system's floor space is little, and equipment installation, operation, convenience easy to maintenance have been saved construction fund and maintenance cost.
Description of drawings
Fig. 1 is the schematic diagram of the utility model extinguishing device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The schematic diagram of extinguishing device of the present utility model as shown in Figure 1, the fluid reservoir 13 that comprises the mixing material that extinguishing chemical and water are housed, fluid reservoir 13 is connected with at least one group of spray system 14 by pipeline, nitrogen starts bottle 7 and is connected with nitrogen power source 6 with gas pipeline by control valve 8, and the nitrogen power source is connected with fluid reservoir.Connecting pipe between nitrogen power source and the fluid reservoir is provided with pressure-reducing valve 10.
Nitrogen power source 6 is provided with a bottle container value 9.
In order to be applicable to cold district, and do not need examination spray regularly, the conveyance conduit 2 between sectioning valve and shower nozzle is the dry type pipeline.
Pipeline 5 between fluid reservoir and the spray system is the wet type pipeline.
For safe in utilization, on fluid reservoir, be connected with Pressure gauge 12 and safety relief valve 11 respectively.
