Description
Technical field
This utility model relates to a kind of water base extinguishing device of prefabrication type, belongs to fire-fighting equipment technical field.
Background technology
The most common fire-fighting prefabrication type extinguishing device, uses gas-powered, such as: storage pot type water mists goes out more
Fire device, storage pot type synthetic foam sprayer unit and cabinet type fire extinguisher of heptafluoropropane, it drives source of the gas to be high pressure nitrogen.Produce
Product in use, are to allow high pressure nitrogen, by decompressor (valve), gas pressure is reduced to system design temperature, drive phase
Close firing-fighting medium and implement fire extinguishing.Owing to source pressure is compared with there being a bigger pressure differential fall between design pressure, system is caused to exist
During use, decompressor (valve) often occur by impact failure, effect of easing stress is unstable, affects extinguishing chemical conveying and spurts
Deng.Especially with driving gas to be released, drive pressure more and more lower, drive gas can not be used effectively completely etc. one to be
Row problem.
Summary of the invention
The technical problems to be solved in the utility model is, the shortcoming overcoming prior art, proposes one and uses carbon dioxide
As the water base extinguishing device of prefabrication type driving gas.
This utility model is that the technical scheme solving the proposition of above-mentioned technical problem is: a kind of water base extinguishing device of prefabrication type,
Including: storage tank and driving bottle；Described driving bottle connects described storage tank by driving pipe；It is sequentially arranged with decompression on described driving pipe
Orifice plate and check valve；Described driving pipe gos deep in described storage bottle to bottom it；Described storage tank built with drain pipe, described drain pipe
And it is disposed with dividing plate between described driving pipe；Described drain pipe is positioned at the part outside described storage tank and installs startup valve, filtration successively
It is connected with fire-fighting system pipe network after device；Described fire-fighting system pipe network includes pipeline and waterfog head；Note it is also equipped with on described storage tank
Liquid valve；Described driving bottle is built with carbon dioxide, and described storage tank is built with extinguishing chemical；Described extinguishing chemical is potassium acetate aqueous solution.
Such scheme is further improved by: equipped with liquidometer on described storage tank.
Such scheme is further improved by: described tank bottom is equipped with atmospheric valve.
Such scheme is further improved by: be also equipped with Pressure gauge and relief valve at described liquid-filling valve.
Such scheme is further improved by: be also equipped with pressure switch on described drain pipe.
Such scheme is further improved by: described storage tank and driving bottle are installed on a framework.
The water base extinguishing device of prefabrication type that this utility model provides replaces nitrogen to be driven with carbon dioxide, normal temperature condition
Under, carbon dioxide is in liquid phase in bottle, and pressure is relatively low, about 5.73MPa(20 DEG C)；And nitrogen is generally 15MPa(DEG C).
So, reduce storage pressure, safer.And, the carbon dioxide of liquid pressure remained steady before completely vaporizing, permissible
Being considered a relatively stable constant pressure source, the beneficially realization of spraying droplet, and droplet is thinner, is conducive to this prefabrication system
Later stage engineer applied；Meanwhile, increasing additive, reduce the HRR of flame in water, fire extinguishing procedure is substantially accelerated.More
Further, this utility model uses pressure reducing orifice to replace air relief valve to reduce pressure, thus avoids air relief valve to be washed out completely
Risk, reduces operation and maintenance cost.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is one preferred embodiment institute structural representation of this utility model.
Detailed description of the invention
Embodiment
The water base extinguishing device of prefabrication type that the present embodiment provides, as it is shown in figure 1, include: be installed in the storage tank on framework 1
15 and drive bottle 2；Drive bottle 2 by driving pipe 12 to connect storage tank 15；Drive and be sequentially arranged with pressure reducing orifice 4 and check valve on pipe 12
8；Drive on bottle 2 equipped with cylinder valve 3；Pipe 2 is driven to go deep in storage bottle 15 to bottom it；In storage tank, 15 equipped with drain pipe 14, drain pipe
It is disposed with dividing plate between 14 and driving pipe 12；The part that drain pipe 14 is positioned at outside storage tank 15 is sequentially installed with startup valve 9, filter
It is connected with fire-fighting system pipe network after 10；Liquid-filling valve 7 it is also equipped with on storage tank 15；Driving bottle 2 built with carbon dioxide, storage tank 15 is built-in
There is potassium acetate aqueous solution as extinguishing chemical.Fire-fighting system official website includes the waterfog head spread everywhere and connects the pipe of waterfog head
Road.
Liquidometer 13 it is also equipped with on storage tank 15.Equipped with atmospheric valve 16 bottom storage tank 15.Pressure gauge 6 it is also equipped with at liquid-filling valve 7
With relief valve 5.Pressure switch 11 it is also equipped with on drain pipe 12.Pressure switch 11 induction pressure, and then open fire-fighting system, it is achieved
The closed loop control principle of fire-fighting system.
Carbon dioxide is irrigated in advance in driving bottle 2.Carbon dioxide is basic in liquid phase in bottle, and pressure of the inside of a bottle is about
When 5.73MPa(20 DEG C).It is the water that with the addition of potassium acetate in storage tank 15.After the cylinder valve 3 driving bottle 2 is opened, carbon dioxide warp
After crossing pressure reducing orifice 4 decompression deceleration, then by check valve 8, enter storage tank 15；In storage tank 15, pressure increases, and opens until driving
Dynamic valve 9 is opened, and extinguishing chemical is gushed out from drain pipe 14, enters fire-fighting system pipe network, is sent at each waterfog head, in pressure effect
Under, put out a fire with the ejection of water smoke form.
Owing to carbon dioxide is become gas phase to need to absorb heat by liquid phase, in order to prevent water freezing and reduce carbon dioxide
Dissolubility in water, adds the salt such as potassium acetate, potassium chloride wherein, simultaneously as drive pipe 12 to be inserted into storage tank 15
Bottom, the extinguishing chemical in storage tank 15, under the drive of carbon dioxide, constantly seethes, and further stops frost.Dividing plate is then used
Come isolation drive pipe 12 and drain pipe 14, prevent carbon dioxide from directly running out of from drain pipe 14, lose driving effect.
This utility model is not limited to above-described embodiment, the technical scheme that all employing equivalents are formed, and all falls within this reality
Protection domain with novel requirement.
