Very early detection and non-destructive fire-extinguishing device and method for fire disaster in small space

Abstract

The invention discloses a very early detection and non-destructive fire-extinguishing device and method for a fire disaster in a small space. The very early detection and non-destructive fire-extinguishing device comprises a detection cavity and a fire extinguishing cavity which are independent of each other. A fan, a detection plate, a first flame detection module and a second flame detection module are arranged in the detection cavity. The detection cavity communicates with the outside through an air inlet pipeline and an exhaust pipeline. The sensitivity of the first flame detection moduleis different from that of the second flame detection module, and the first flame detection module and the second flame detection module are sequentially arranged at a position where air flows throughto determine whether a fire behavior exists in the monitored space, and when the fire behavior exists in the monitored space, the detection plate sends an instruction to the fire extinguishing cavity.The fire extinguishing cavity comprises a spray power device, a spray pipeline and a nozzle. The spray power device receives the instruction to generate an instant shock to spray a fire extinguishingagent into the monitored space through the spray pipeline and the nozzle, so that non-destructive fire extinguishing is realized.

Description

technical field [0001] The invention relates to a very early detection and non-destructive fire extinguishing device and method for a fire in a small space. Background technique [0002] Important data centers, archives, cultural relics, state key laboratories and other important places where electronic equipment, archives or precision instruments are stored, once a fire occurs, it will cause irreparable losses. It is very necessary to carry out research on very early detection of fire and non-destructive fire extinguishing device for the small space where these key items are stored. At present, in these special places in China, the method of combining smoke detectors, temperature detectors and gas fire extinguishing systems is mainly used for protection, but there are problems such as monitoring blind spots, untimely alarms, and destructive fire extinguishing. [0003] Foreign developed countries attach great importance to the research on very early detection and early war...

AI Technical Summary

Problems solved by technology

But generally speaking, due to the relatively late development of relevant research in my country, especially in the rapid and accurate detection of fires in special small spaces and the optimization design of fire extinguishing devices, there are high false alarm rates, long passive detection times, and difficulties in post-fire treatment and damage. It cannot meet the special needs of key industries such as banking, military industry, communication, and electric power.
