Abstract
An inner cooling-type aerosol fire extinguisher comprises a shell, a reaction chamber, and a cooling chamber; wherein the reaction chamber is provided with a fire extinguishing agent column inside, chemical cooling agent powder is filled around the fire extinguishing agent column, the upper part of the reaction chamber is provided with the cooling chamber, the cooling chamber is sequentially provided (from bottom to top) with an orifice plate, a chemical cooling agent layer, a metal filter mesh, an isolation ring, a metal filter mesh, a chemical cooling agent layer, an anti-damping film, and a top cover orifice plate, and the orifice diameters of the orifice plate, the metal filter mesh, and the top cover orifice plate sequentially decreases. The extinguisher combines the physical cooling method and the chemical cooling method, has the cooling agent around the fire extinguishing agent column and the aerosol spraying path, does not change the reaction rate of the aerosol fire extinguishing agent, and can make the fire extinguishing agent normally combust. The utility model has the advantages of simple structure, convenient preparation, safe and reliable use, good cooling effect, maximally reduced aerosol spray nozzle temperature, and enhanced effective fire extinguishing component, and can dramatically increase the efficiency and application scope of the aerosol fire extinguishing agent.
Description
Technical field
The utility model relates to a kind of fire fighting extinguisher, particularly interior cooled aerosol fire-extinguishing device.
Background technology
At present, accepted widely from the aerosol fire-extinguishing method, and selected in many places rapidly, and its tangible characteristic of environmental protection and high-effect fire-extinguishing are indubitable.But existing aerosol fire-extinguishing device all is that to rely on the combustion reaction of invented solid gas aerosol extinguishing agent to generate fire extinguishing aerocolloidal, this extinguishing device is in the aerosol generative process, because fierce oxidation reaction takes place, the temperature of combustion reaction is up to 600～1200 ℃, and, make its generator exports temperature very high, even very strong flame ejection is arranged with thermal-flame, the safety in utilization that this has just had a strong impact on it is restricted applying of aerosol fire-extinguishing technology.For this reason, have in extinguishing device (placing the device of generator), take variety of way to reduce temperature, for example in extinguishing device, increase cooling space or physical methods such as fire-proof plate are set at extinguishing device spout place, the result makes the extinguishing device complex structure, volume increases, and increases the quality of device simultaneously, the cost height, bring very big inconvenience to installation, and cooling-down effect is not remarkable.
Summary of the invention
The purpose of this utility model provides a kind of interior cooled aerosol fire-extinguishing device, the aerosol ejection temperature of fire extinguisher is reduced significantly, the effective ingredient of putting out a fire simultaneously can be improved, fundamentally solve aerosol extinguishing agent apparatus structure complexity, volume is big, the cost height, awkward problem is extensively promoted aerosol fire-extinguishing The Application of Technology field.
The purpose of this utility model realizes by following manner: cooled aerosol fire-extinguishing device in a kind of, comprise shell, reative cell and cooling chamber, the reative cell middle part is provided with the extinguishing chemical powder column, fill the chemical coolant powder in the reative cell around the extinguishing chemical powder column, reative cell top is provided with cooling chamber, cooling chamber is provided with orifice plate, chemical coolant layer, metal screen, shading ring, metal screen, chemical coolant layer, moisture-proof film and top cover orifice plate from down to up successively, wherein, orifice plate, metal screen, top cover orifice plate aperture reduce successively.
The utlity model has following advantage:
The utility model with cooling agent place reative cell extinguishing chemical powder column around and aerosol spray path, therefore it does not change the reaction rate of aerosol extinguishing agent, do not influence the ignition performance and the combustibility of medicament, can make reative cell powder column normal combustion, lack and produce or do not produce residue, the thermal-flame that produces when stopping the powder column burning sprays outward, reduce the temperature of aerosol cloud effectively, it is simple in structure, and is easy to make, safe and reliable, good cooling results reduces the aerosol spray outlet temperature to greatest extent, strengthens effectively fire extinguishing composition simultaneously, improved fire-fighting efficiency, the aerosol fire-extinguishing device overall structure is simplified, and volume-diminished has guaranteed that flame does not leak, eliminate the possibility that causes secondary damage, improved aerosol extinguishing agent efficient and range of application greatly.
The utility model is applicable to the place of all available aerosol fire-extinguishings such as electrical equipment, computer floor, cable duct, switchgear house, transformer room, and can be applicable to the fire extinguishing of the relative seal cavities of mobile device such as automobile engine, tank, oil truck.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Cooled aerosol fire-extinguishing device in a kind of, comprise shell 1, reative cell 2 and cooling chamber 3, aerosol extinguishing agent is pressed into the cylindric or cellular powder column 4 of certain size, the paper web that the overcoat moistureproof paper is made, be placed on reative cell 2 centers, fill chemical coolant powder 5 in the reative cell 2 in extinguishing chemical powder column 4 cylindrical periphery or the honeycomb hole, and compacting, extinguishing chemical powder column 4 is staggered compartment with chemical coolant powder 5 and places.Reative cell 2 tops are provided with cooling chamber 3, cooling chamber 3 is provided with orifice plate 6, chemical coolant layer 7, metal screen 8, shading ring 9, metal screen 10, chemical coolant layer 11, moisture-proof film 12 and top cover orifice plate 13 from down to up successively, wherein, orifice plate 6, metal screen 8,10, top cover orifice plate 13 apertures reduce successively, do not cause vibrations to guarantee that aerosol releases, top cover orifice plate 13 is threaded with shell 1 in order to fixing all interior powder charge agent.Be provided with cellular in the chemical coolant layer 7,11 or diagrid shape mesh.Shell 1 is provided with lead fairlead 14, and ignition medicine and powder column 4 are packaged together.Lead is connected with the ignition medicine, behind the signal of telecommunication of receiving startup, lights powder column 4.Powder column 4 begins to take place violent oxidation reaction, produce a large amount of heat, simultaneously, powder column 4 is successively to be reacted to the bottom by the upper surface, in reaction at the beginning, the heat that the reaction of powder column 4 upper stratas generates passes to the chemical coolant powder 5 on top immediately, chemical coolant issues the reaction of separating estranged in the temperature of 200 degree Celsius, absorb a large amount of heat, generate inert gas and alkaline metal salt (being all the high-quality extinguish material) simultaneously, in ensuing reaction, powder column 4 constantly reacts, and cooling agent constantly adds reaction on every side, shading ring 9 formed insulating spaces can not release combustion residue simultaneously, the result makes generator spout temperature remain on very low level, thereby finishes whole tasks of cooling in the chemistry, and the aerosol extinguishing agent that makes the high temperature generation is when releasing, the spout temperature is very low, having overcome original temperature height has the drawback of flame ejection, has stopped the secondary harm that original aerosol fire-extinguishing process may produce, and makes aerosol extinguishing agent can obtain promotion and application in more wide field.
