Abstract

The invention relates to an automatic fire-extinguishing device using superfine dry powder. A pressure tank is provided with an obconical bottom, a supporting base is mounted on the obconical bottom of the pressure tank, the pressure tank is filled with a superfine dry powder extinguishing agent and expellant gas, a bottle head valve is provided with a ball valve and a polymer hose which is connected with an outlet of the ball valve and is used for filling the expellant gas, the tail end of the polymer hose is provided an gas-filling one-way valve and a gas-pressure meter connected with an outlet of the gas-filling one-way valve, the bottle head valve is provided with a gas-filling connector, a gas-pressure meter connector, a gas-pressure meter, a detection connector and a pressure sensor, and an electrical signal input by the pressure sensor is connected with an alarm display. By adopting the polymer hose, the superfine dry powder extinguishing agent with a high extinguishing function can be directly transported and ejected to a fire occurrence at early stage, the detection, extinguishing and fighting effects of a fire and in particular to a fire at early stage are obviously enhanced, the comprehensive, all-weather fire detection and extinguishing protection on key dangerous sources or key dangerous areas in closed and half-closed spaces can be achieved, and the problem of influencing the extinguish effect due to overlarge ejecting surplus ration of the superfine dry powder extinguishing agent can be solved by the designs of the pressure tank with the obconical bottom and a siphon way.

Description

technical field [0001] The invention belongs to fire-fighting and fire-extinguishing equipment, in particular to an ultra-fine dry powder automatic fire-extinguishing device for fighting early fires. Background technique [0002] Ultrafine dry powder fire extinguishing agent has small particle size, large specific surface area per unit mass, high activity, and has the characteristics of fast fire extinguishing speed and high efficiency. After the ultrafine dry powder fire extinguishing agent is released, most of its fine particles can be quickly dispersed and suspended in the air. A relatively stable fire extinguishing aerosol is formed in the air, so the ultra-fine dry powder fire extinguishing agent can be used not only for full flood fire protection for confined spaces, but also for local fire protection for specific protected objects, and has broad application prospects. [0003] The existing superfine dry powder fire extinguishing equipment mainly includes: pipe network...
