Fire fighting system using superfine dry powder as extinguishing agent and using method thereof

Abstract

The invention relates to a fire fighting system using superfine dry powder as an extinguishing agent. The fire fighting system comprises two parts, i.e., a delivery subsystem and a control subsystem, wherein parts of the control subsystem are connected with the delivery subsystem through a pipe network of the delivery subsystem; the delivery subsystem comprises an air compressor, a high-pressure gas cylinder, a safety valve, a check valve, the pipe network, a dry powder extinguishing agent spray nozzle and novel superfine monoammonium phosphate extinguishing power; and the control subsystem comprises a detector, an electric valve, an alarm and a fire fighting control center. A using method of the fire fighting system using the superfine dry powder as the extinguishing agent comprises seven major steps. The fire fighting system disclosed by the invention can be widely used for the extinguishment of the pipe network of a large-scale closed building and has an extensive application prospect and practical significance in the technical field of public security fire fighting.

Description

technical field [0001] The present invention relates to a fire extinguishing system, more precisely, relates to a fire extinguishing system using superfine dry powder as a fire extinguishing agent and its application method. It uses superfine ammonium phosphate dry powder as a fire extinguishing agent and is applied to large A pipeline network fire extinguishing for closed buildings belongs to the technical field of public security fire protection. Background technique [0002] The frequent occurrence of serious fires in large-scale high-rise buildings in China has brought great threats to the safety of people's lives and property, and has aroused great attention from all walks of life. This puts forward stricter requirements for fire prevention, and also requires further improvement of buildings. The fire-fighting facilities of the building itself, especially the densely populated high-rise buildings. The main fire extinguishing media that can be equipped for large buildin...

Problems solved by technology

Using a hand-held fire extinguisher to extinguish fire requires personnel to operate at the fire scene, and the timeliness and automation are poor, and its fire extinguishing ability is greatly limited for areas that are difficult for personnel to enter.

The high-pressure gas cylinders in the hanging or wall-mounted automatic dry powder fire extinguishing device take up a lot of space, the fire extinguishing space is limited, and the storage of high-pressure gas cylinders has strict environmental requirements, it is not suitable for rooms with high temperature, and affects the appearance
