[0003]
The particle size of smoke particles in fire smoke is larger than the wavelength of visible light, that is, it is opaque to visible light and has complete shading, which will greatly reduce visibility; the dimming property of smoke causes psychological panic to people, making people in a limited area when a fire occurs. If no effective escape route is found within the time limit, the chance of escape will be lost
When the visibility is less than 3 meters, it is very difficult for personnel to escape, and the time of staying in the fire scene is greatly lengthened, which increases the further harm caused by the high temperature and poisonous smoke of the fire.
[0006]
However, due to the complex situation in the fire scene and many dangerous situations, the hand-held smoke suppression device is not easy to use in many cases, so it is of great significance to develop a fire smoke suppression device with a comprehensive range of applications

Embodiment 1
[0047] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a throwable fire smoke elimination device includes a Hartmann whistle 1, an integrated head base 2 and a gas storage unit.
[0048] The gas storage unit is in the shape of an ellipsoid; the upper part of the gas storage unit is a hollow shell 3, and the lower part is a solid base 6; Set the dust plug 4.
[0049]In this embodiment, the inflation port 5 extends from the bottom of the solid base 6 to the top of the solid base 6 and communicates with the hollow casing 3 . Inflate nitrogen or carbon dioxide into the hollow shell 3 through the air charging port until the internal pressure of the gas storage unit reaches 0.4~0.7MPa.
[0050] The Hartmann whistle 1 and the integrated head base 2 jointly constitute the integrated head, and the integrated head is sealed and connected with the gas storage unit. Specifically, the integrated head base 2 is in sealing connection with the top of the hollo...

Abstract
The invention discloses a throwing type fire smoke eliminating device and a smoke eliminating method, and belongs to the technical field of fire protection. The device comprises a hartmann whistle, an integrated head base and an gas storage unit, wherein the gas storage unit is in sealed connection with the integrated head base, the integrated head base is provided with a through hole used for mounting the hartmann whistle, the hartmann whistle is arranged on the through hole and can move up and down along the through hole, and a sealing gasket used for preventing gas in the gas storage unit from leaking from the outer wall of the hartmann whistle and the through hole is arranged between the outer wall of the hartmann whistle and the through hole. According to the device, the pneumatic sound source of the hartmann whistle can be used for generating sound wave to agglomerate the fire smoke, so that the device is not easy to damage, and is more suitable for the severe environment of the fire scene; the device is convenient to carry and wide in application range; and the visibility of a fire scene area can be greatly improved within several seconds by virtue of the device, meanwhile, the fire potential can be weakened, so that the escape rate of the fire scene personnel is greatly improved, and the device has remarkable social benefits and is suitable for popularization and application.
Description
technical field [0001] The invention relates to the technical field of fire safety, in particular to a throwable fire smoke elimination device and a method for eliminating smoke. Background technique [0002] For human beings, fire is a huge disaster that is being prevented all the time, and it causes a large number of casualties and property losses every year. In a fire, the main cause of death is the smoke produced by the fire. The smoke not only affects the human respiratory tract, but also has extremely low visibility in the smoke, which hinders the escape of the personnel. Accounted for more than 80%. [0003] The particle size of smoke particles in fire smoke is larger than the wavelength of visible light, that is, it is opaque to visible light and has complete shading, which will greatly reduce visibility; the dimming property of smoke causes psychological panic to people, making people in a limited area when a fire occurs. If an effective escape route is not found ...
