The specific embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Fig. 3 is the structural representation of the utility model extinguishing device, and as shown in the figure, extinguishing device of the present utility model specifically comprises: top cover 1, housing 2 and porous member 3.
Again as shown in Figure 3, extinguishing device of the present utility model also comprises initiator 4 and baffle plate 5.Initiator 4 is connected with top cover 1, is contained in the porous member 3.Baffle plate 5 sealing-ins are at the opening part of housing 2.
Concrete, initiator 4 is contained in the central authorities of top cover 1, fixes by screwed hole.One annular nose is arranged below the top cover 1, pin thread is arranged on it.And internal thread is arranged at porous member 3 tops, is connected with the internal thread of top cover 1.Be distributed with some screwed holes on the circumference of top cover 1, be used for connecting trumpet-shaped housing 2.Housing 2 lower ends and baffle plate 5 sealing-ins.Porous member 3, housing 2, baffle plate 5 are packaged into an enclosure space, interior shape powder extinguishing agent 6.Initiator 4, top cover 1 and porous member 3 are formed gas generator, and its inner chamber is called first pressure chamber 71; Porous member 3 outer walls, housing 2 and dry powder layer surround second pressure chamber 72.In the supersonic speed gas generator, there is the thin film card to cover.
Fig. 4 is the schematic diagram of the utility model extinguishing device porous member, and as shown in the figure, first spray orifice 31 of porous member 3 is distributed in the bottom of porous member 3, and first spray orifice, 31 axis and porous member 3 axial angles are 0 to 90 degree.And second spray orifice 32 is distributed in the sidepiece of porous member 3.Again referring to shown in Figure 3, the outside of second spray orifice 32 is towards second pressure chamber 72 that is surrounded by the last plane of dry powder 6 and housing 2 and porous member 3 outer walls.The axial angle of the axis of second spray orifice 32 and porous member 3 is greater than 45 degree, for example be 45 to 135 degree, specifically the axis of second spray orifice 32 and porous member 3 axial angles can be 90 degree, just second spray orifice, 32 axis and porous member 3 angle radially are 0 degree, and the second such spray orifice 32 can be become radially spray orifice.
The schematic diagram of the utility model extinguishing device second spray orifice as shown in Figure 5 again, second spray orifice 32 is the side spray orifice, and tilts towards a direction, is called the spiral sides spray orifice.
When static state, the pressure of first pressure chamber 71 and second pressure chamber 72 is zero.After extinguishing device received starting current, initiator 4 was at first moved, and conflagration discharges a large amount of combustion gas, formed the gases at high pressure product in first pressure chamber 71 rapidly.Combustion gas is full of first pressure chamber 71, and the 71 continuous superchargings of first pressure chamber.When reaching the tension limit of the first pressure chamber film, film is broken through by high pressure draught, and second spray orifice 32 is opened, and high temperature and high pressure gas highly sprays from second spray orifice 32, and be full of second pressure chamber 72 rapidly, reach the transient equilibrium of the pressure of first pressure chamber 71 and second pressure chamber 72.At this moment, in second pressure chamber 72 strong flow perturbation is arranged, the powder extinguishing agent 6 that is in contact with it is pulverized and quickened, the dry powder at this place is atomized fully, and disturbance in housing 2, and activity is improved.
In this process, because the appearance of second pressure chamber 72, pressure in the pressure chamber 71 of winning can be discharged in second pressure chamber 72 by side second spray orifice 32, surge pressures in first pressure chamber 71 reduce about 20% one 35%, directly reduced strength of materials requirement to porous member 3, reduce porous member 3 difficulty of processing, reduced production cost and technology cost.
Burning is proceeded, and the pressure in first pressure chamber 71, second pressure chamber 72 constantly increases, and makes that the pressure in the whole housing 2 constantly raises.Because powder extinguishing agent 6 is incompressible, so pressure can be delivered to baffle plate 5 places by powder extinguishing agent 6.When meeting and exceeding the tension limit of baffle plate 5, baffle plate 5 is broken through, and powder extinguishing agent 6 leaves the extinguishing device directive scene of a fire under the effect of high velocity air.At this moment, the powder extinguishing agent 6 around second pressure chamber 72 also sprays to the scene of a fire along with powder extinguishing agent 6 one superhigh speeds that activated by first pressure chamber 71, rather than prior art is the same is dropped or become residual dry powder by free fall type.Under the effect of high speed inert gas and high speed dry powder jet, the condition of a fire is controlled and extinguished by moment.
The dry powder of powder extinguishing agent 6 has been finished the secondary refinement in this process, mainly contains following several form:
Dry powder is subjected to the effect of high-speed jet and is recommended at a high speed, forms high speed dry powder stream, because the speed difference of dry powder and air, dry powder is shredded into the dry powder particulate.
The coverage rate of high-speed jet is bigger, and inner walls is pointed near the high-speed jet direction that second jet pipe gushes out in the position, and part dry powder strikes on the inner walls under the high-speed jet effect, and dry powder particle produces the dry powder particulate because of collision.
Dry powder self quickens to move downward, and high-speed jet pushes away dry powder on protected goods and materials or ground, and dry powder particle produces the dry powder particulate because of collision.
The high-speed jet that first jet pipe of porous member and second jet pipe eject is taper to be penetrated, and each jet awl all intersects mutually, and dry powder is formed two strands of similar dry powder streams in the infall collision under jet promotes, and per share dry powder Liu forms the dry powder particulate.
The spiral air flow that second pressure chamber produces can make with its dry powder particle to contact portion and move downward along device main axis rotation and high speed.The dry powder particle that rotates with do straight-line dry powder particle and in moving downward process, bump and produce the dry powder particulate.
Because the existence of second spray orifice makes that the powder extinguishing agent in the extinguishing device can fully be activated, fire extinguishing effectiveness is improved, the extinguishing device of same model, its protection enlarged areas 15%--25%.
Kinetic energy when therefore extinguishing device of the present utility model can increase the dry powder preshoot and the dry powder that makes prior art fail to be utilized fully are fully used, and make effective protection enlarged areas, and quenching distance increases, and have improved the fire extinguishing effectiveness of dry powder; Second pressure chamber has activated fails the dry powder that activated by supersonic airstream in the prior art, make them can obtain enough speed and energy, participates in fire extinguishing procedure, and residual dry powder amount is obviously reduced; And, the strength of materials of making porous member is required also corresponding reduction because second pressure chamber has reduced the surge pressure in the gas generator, and also reduced difficulty of processing simultaneously, make production cost reduce.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the spirit and scope of technical solutions of the utility model.
