The suspended dry powder automatic fire extinguishing device is composed of tank body, modular valve, pressure gauge, lifting ring and other components. It is filled with sodium bicarbonate dry powder fire extinguishing agent and filled with an appropriate amount of driving gas nitrogen.
This product has the advantages of high fire extinguishing efficiency, low corrosivity, good insulation performance and long-term storage without deterioration. A sprinkler bulb is installed at the valve. When a fire breaks out, the temperature rises, and the internal extinguishing agent decomposes, vaporizes, and expands. When the expansion force exceeds the compressive strength of the glass tube, the glass tube will explode, and the carbon dioxide and ammonia produced by vaporization will directly capture the oxygen in the air. The ammonia can effectively reduce the temperature of the air, so as to achieve the purpose of extinguishing the fire.
The ultra-fine dry powder spontaneous combustion device can be used in places that are unattended and cannot be solved by traditional methods, such as distribution cabinets in distribution rooms, cable trenches, cable interlayer, communication machine stations, etc. it can realize passive spontaneous startup, and extinguish the fire at the initial stage of fire, realize early control, and reduce losses. For example, the internal environment of cable tunnel, cable interlayer and cable shaft is generally narrow, or the length is long, the height is high, and the support is dense, so the situation is complex. Because in similar places, many fire-fighting systems with pipe networks are difficult to work normally, this device is especially suitable for similar places.
Hanging fire extinguisher superfine dry powder extinguishing agent is a kind of fire extinguishing device using superfine dry powder as fire extinguishing agent. Compared with ordinary dry powder extinguishing agent, it has small particle size, large surface area and high fire extinguishing efficiency. Superfine dry powder extinguishing agent is mainly a composite material polymerized by a variety of inorganic substances. Compared with ordinary dry powder extinguishing agent, it has small particle size, large surface area, high fire extinguishing efficiency, no caking, no moisture absorption and no caking to protective substances, It has no impact on the protective objects. In addition, the ozone depletion potential (ODP) and greenhouse effect potential (GWP) of the superfine dry powder fire extinguishing agent of the suspended fire extinguisher are zero, which is non-toxic and harmless to human skin and respiratory tract, and has no corrosion to protectors.
