Embodiment Construction

[0020] The specific device of the present invention manufactured according to the accompanying drawings is set forth in detail below.

[0021] Such as figure 1 As shown, the embodiment of the present invention represents an inert gas generator comprising a gas turbine 10 . The gas turbine 10 is started by a starter motor 12 . The starter motor 12 provides sufficient power to the compressor and other auxiliary systems during the initial driving speed range until the engine reaches a self-sustaining speed. When self-sustaining speed is reached, the starter motor is decoupled from the gas turbine.

[0022] A compressor, mechanically coupled to the starter motor, compresses air taken from the atmosphere. Either centrifugal compressors or axial compressors can be used in this configuration. Air is drawn into the compressor by means of an air intake 16 commonly referred to as a "bell mouth". In order to minimize the pressure loss of the compressor 14, it is necessary to provide...

Abstract

Disclosed is an inert gas generator to produce a large quantity of inert gas within a short period of time .The inert gas generator comprises: a gas turbine consisting of a starter motor, compressor, combustor and turbine; and afterburner being connected to the exit of the gas turbine to re-burn the gas of once burned in the primary combustor and being equipped with a flame stabilizer; a cooling chamber being equipped with spray nozzles to eject water to decrease the gas temperature in the afterburner exit; an evaporator set to further cool the gas-steam mixture from the afterburner; a cooling chamber and spray nozzles; an exhaust nozzle to guide the direction of the inert gas-steam mixture of low temperature and oxygen content; and a controller for controlling the starter motor, the fuel pump and combustor. The inert gas generator mounted on a movable vehicle can promptly suppress the fire occurred in various places with least amount cost possible.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a gas generating device for producing a large amount of inert gas with low oxygen content in a short time. The invention also relates to a vehicle equipped with such a gas generating device for fire extinguishing. Background technique [0002] Usually, water or inert gases like carbon dioxide, nitrogen, Halon 1301 (Halon 1301) and exhaust (Inergen) have been used as extinguishing media in fire extinguishing. Of these substances, water is the most effective extinguishing agent and is recognized throughout the world to play a major role in extinguishing fires. Here, the fire extinguishing effect refers to the effect of cooling and isolating from the air at the same time when extinguishing a fire. [0003] However, when water is used as a fire extinguishing agent, in order to completely extinguish the fire, water needs to be sprayed on the surface of all fire-igniting substances, whi...
