Abstract
The utility model discloses a medium-multiple inert gas foam generator. The medium-multiple inert gas foam generator comprises a round pipe body, wherein a No.1 conical pipe body integrally is arranged at one end of the round pipe body, and a No.2 conical pipe body is connected with the other end of the round pipe body, a foam outlet is formed at the end part of the No.1 conical pipe body; an inert gas inlet is formed at the end part of the No.2 conical pipe body; a foaming mesh is arranged in the round pipe body in the radial direction; a mixture liquid nozzle is arranged in the No.2 conical pipe body facing the foaming mesh; and the mixture liquid nozzle is communicated with a guide pipe protruding out of the No.2 conical pipe body. The medium-multiple inert gas foam generator has the function of dual isolation-smothering, and can improve the fire extinguishing efficiency. The medium-multiple inert gas foam generator can be used for locally protected places and for total flooding fire extinguishing by spraying the foam group to a closed protected area through the outlet and the connection pipe. The medium-multiple inert gas foam generator particularly suits underground fire hazard of a coal mine.
Description
Technical field
The utility model relates to a kind of fire-fighting fire-extinguishing equipment, is specifically related to a kind of medium multiple inert gas foam generator.
Background technology
The operation principle of the medium expansion foam generator that generally uses is at present, make the foam mixing liquid atomizing by the nozzle in the generator, foam mixing liquid while and the effect of generator air entry inhaled air after the atomizing, and form a large amount of foam groups by foam screen and foam, the foam group who is produced causes conflagration area by the outlet of the generator kuppe of flowing through, form foam blanket on the comburant surface, thereby reach the purpose of the fire that suffocates, also have the effect of cooling simultaneously.The existing deficiency of this type of generator is: the bubble mobility that is produced is relatively poor, can not carry more at a distance.Therefore, this type of generator is mainly used in the place of localised protection, for example the fire in first, second, Class C wet tank district.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, a kind of fire-fighting efficiency height is provided, can be used in the medium multiple inert gas foam generator that total flooding is put out a fire.
The technical solution of the utility model is: a kind of medium multiple inert gas foam generator, comprise a circular body, it is characterized in that: an end of described circular body has been wholely set conical tube No. one, the other end of circular body is connected with conical tube No. two, a described conical tube end is provided with foam outlet, the end of No. two conical tubes is provided with inert gas import, described circular internal diameter of tube body is to being provided with foam screen, be provided with the mixed liquor nozzle towards foam screen in described No. two conical tubes, the mixed liquor nozzle is connected with the mozzle that stretches out No. two conical tubes.
Described foam screen is connected with the inwall of circular body by folder net circle.
Described circular body and No. two conical tube junctions are provided with sealing ring.
The utility model compared with prior art has the following advantages:
(1) the utility model is provided with the inert gas air inlet on generator, inject inert gas (nitrogen or carbon dioxide) continuously with certain pressure by the inert gas air inlet, foam mixing liquid effect after wherein a part of inert gas and the generator nozzle atomization also forms a large amount of foam groups by foam screen and foams, the power that the inert gas of remainder flows as the foam group, thus the foam group flowability of formation is strengthened.
(2) after this generator generated the inert gas that mixes with the foam group flows into the protection zone, with the foam group in the protection zone, have dual isolation suffocate (froth bed isolate suffocate, inert gas isolate suffocate) function, thereby improved fire-fighting efficiency.
(3) the utility model generator can not only be used for the place of localised protection; but also can be applicable to the total flooding fire extinguishing; the foam outlet connecting pipe of foam group by generator is delivered in the airtight protection zone puts out a fire, and the utility model medium multiple inert gas foam generator is particularly suitable for the colliery underground fire.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
A kind of medium multiple inert gas foam generator as shown in Figure 1, comprise a circular body 1, one end of described circular body 1 has been wholely set conical tube 2 No. one, the other end of circular body 1 is connected with conical tube 3 No. two, described conical tube 2 ends are provided with foam outlet 5, the end of No. two conical tubes 3 is provided with inert gas import 6, radially be provided with foam screen 7 in the described circular body 1, be provided with mixed liquor nozzle 8 towards foam screen 7 in described No. two conical tubes 3, mixed liquor nozzle 8 is connected with the mozzle 9 that stretches out No. two conical tubes 3.
Described foam screen 7 is connected with the inwall of circular body 1 by folder net circle 10.
Described circular body 1 and No. two conical tube 3 junctions are provided with sealing ring 4.
The utility model foam screen 7 is installed between foam outlet 5 and the mixed liquor nozzle 8.During work, mixed liquor is delivered to mixed liquor nozzle 8 by mozzle 9, and be sprayed onto on the foam screen 7 after the foam mixing liquid atomizing by mixed liquor nozzle 8, inert gas continues to inject by inert gas import 6, a part inert gas with mix (effect) by the foam solution after the nozzle atomization, generate inert gas foam group by foam screen 7, the inert gas of remainder becomes the power that the foam group is flowed, and the foam group is mobile to strengthen thereby make.Enough being transported in the airtight protection zone by the pipeline that is connected with foam outlet 5 of foam group energy put out a fire.
Claims (3)
1. medium multiple inert gas foam generator, comprise a circular body (1), it is characterized in that: an end of described circular body (1) has been wholely set a conical tube (2), the other end of circular body (1) is connected with No. two conical tubes (3), a described conical tube (2) end is provided with foam outlet (5), the end of No. two conical tubes (3) is provided with inert gas import (6), radially be provided with foam screen (7) in the described circular body (1), be provided with mixed liquor nozzle (8) towards foam screen (7) in described No. two conical tubes (3), mixed liquor nozzle (8) is connected with the mozzle (9) that stretches out No. two conical tubes (3).
