Abstract

The invention discloses a compound portable fire extinguisher which is characterized in that: a fire extinguishing agent storage tank is arranged, and a tank port of the fire extinguishing agent storage tank is sealedly connected with a machine head assembly, an internal cavity of the fire extinguishing agent storage tank is provided with a separator plate connected with the bottom of the storage tank and the side surface of the storage tank, the internal cavity of the fire extinguishing agent storage tank is separated into a first cavity and a second cavity by the separator plate, and the upper parts of the first cavity and the second cavity are communicated with each other; a fire extinguishing agent straw system is arranged to form an inverted Y-shaped structure, a mixing cavity is arranged on the upper part, and the bottom of the mixing cavity is in parallel connection with a first fire extinguishing agent straw and a second fire extinguishing agent straw, an end port of the top of the mixing cavity is connected with a fire extinguishing agent inlet connecting pipe of the machine head assembly, and the first fire extinguishing agent straw and the second fire extinguishing agent straw are respectively inserted into the first cavity and the second cavity; the first cavity is used for being filled with 2-bromo-3,3,3-trifluoropropene or perfluorinated hexanone, and the second cavity is filled with water or water containing an inorganic salt additive. The compound portable fire extinguisher is the clean and efficient compound portable fire extinguisher with combination of clean gas and fine water mist.

Description

technical field [0001] The invention belongs to the technical field of portable fire extinguishers, in particular to a portable fire extinguisher suitable for the combined use of clean gas and fine water mist. Background technique [0002] With the gradual elimination of halon fire extinguishing agent, various halon substitute fire extinguishing agent products are constantly emerging. Compared with dry powder fire extinguishing agent and foam fire extinguishing agent, clean gas and fine water mist are considered to be two clean alternatives to halon, which have the advantages of non-conductivity, no residue after fire extinguishing, and no pollution to equipment and equipment on the fire extinguishing site. It is used for fire protection in various places such as instrument and equipment rooms, computer rooms, library archives, aircraft or ship cabins, etc. Clean gases such as perfluorohexanone and bromofluoropropene mainly use chemical methods to extinguish fires, and the ...
