Supersonic fire extinguishing device

Abstract

The invention relates to a supersonic fire extinguishing device. The supersonic fire extinguishing device comprises a top cover, a shell, a porous part, first initiators, second initiators and a lead wire, wherein the shell is connected with the top cover; the porous part is stored in the shell and is connected with the top cover in a sleeving manner; a first spraying hole is formed in the top of the porous part and is used for spraying supersonic gas from the top of the porous part; a second spraying hole is formed in the side part of the porous part and is used for spraying supersonic gas from the side part of the porous part; the first initiators are stored in the porous part; the second initiators are connected with the first initiators and are stored in the porous part; the lead wire is connected with the first initiators. As the supersonic fire extinguishing device is provided with the many initiators, power is effectively improved and excessively concentrated stress is alleviated; with the first spraying hole and the second spraying hole, a fire extinguishing agent can be sprayed without dead angles, and thus the fire extinguishing efficiency is increased.

Description

technical field [0001] The invention relates to a supersonic fire extinguishing device, in particular to a supersonic fire extinguishing device with multiple initiators. Background technique [0002] With the development of the times, fire extinguishers are installed in many places of work and life for safety needs, but because of special reasons for some goods, water cannot be used to extinguish fires, so dry powder fire extinguishers are needed, and in order to enhance the fire extinguishing of dry powder fire extinguishers Efficiency, there has been a supersonic dry powder fire extinguisher. [0003] Existing dry powder fire extinguishers include a porous member with spray holes and a single initiator, but if there is only one initiator, the power is relatively low and the stress is too concentrated. [0004] And the center line of the nozzle hole in the existing porous member is along the diameter direction of the arc-shaped convex end, so the nozzle holes of the porous...

Problems solved by technology

[0004] And the center line of the nozzle hole in the existing porous member is along the diameter direction of the arc-shaped convex end, so the nozzle holes of the porous member are generally distributed on the arc-shaped surface, and the angle between the direction and the axial direction is not more than 45° °, that is, there is no spray hole at the bottom of the porous part, resulting in the "dead angle" dry powder not being fully atomized, resulting in poor fire extinguishing efficiency
