Problems solved by technology

However, at present, water system fire extinguishers are mainly stored under pressure, that is, most of them are stored with inert gas or CO 2 As a power source to promote the injection of water system fire extinguishing agent, this storage and eruption method, the eruption speed will slow down with time, the fire extinguishing agent is easy to remain and affect the fire extinguishing effect, and the storage of inert gas makes the structure of the fire extinguisher complicated, not easy to carry, and stable in storage poor

Embodiment 1

[0022]Seefigure 1 The structure of the aqueous gas push fire extinguishing device of the present embodiment includes a circularly straightforward cylinder, and the inner cavity of the cartridge is from bottom to the gas chamber 2, the cache cavity 5, the drug storage chamber 1, that is, the gas chamber 2 is At the bottom of the cylinder, the gas reagent and the igniter 3 are filled in the gas chamber 2, in order to ensure the filling effect and avoid high temperature burns after the gas supply ignition, the gas supply can be packaged in the nylon rubber insulation cover. In the medium, gas producing agent can be used as a composition composed of 70% nitrate, 20% melamine and 10% phenolic resin, which can be replaced with other gas replacement. The ignitioner 3 is embedded on the upper surface of the gas producing agent, which is connected to the ignition initiator outside the cylinder through the wire, which belongs to a normal fire extinguisher for the murder, belongs to the commer...

Embodiment 2

[0031]Seeimage 3The structure of the aqueous gas push fire extinguishing device of the present embodiment includes a circularly straightforward cylinder, and the inner cavity of the cartridge is from bottom to the gas chamber 2, the cache cavity 5, the drug storage chamber 1, that is, the gas chamber 2 is At the bottom of the cylinder, the gas reagent and the igniter 3 are filled in the gas chamber 2, in order to ensure the filling effect and avoid high temperature burns after the gas supply ignition, the gas supply can be packaged in the nylon rubber insulation cover. In the medium, gas producing agent can be used in a composition of 75% nitrate, 15% melamine and 10% phenolic resin to produce an inert gas, or other gas replacement can also be used. A ignitioner 3 is buried on the upper surface of the gas producing agent, which is connected to the ignition lator 3 through the wire.

[0032]Above the gas chamber 2 is a cache cavity 5, the cache cavity 5 is in communication with the gas ...

Embodiment 3

[0038]Unlike Example 2, the gas chamber 2, the cache 5, and the inner diameter of the cache cavity 2, the cavity 2, the cavity 5, and the drug storage chamber 1 are 32. : 5: 300, and the height of the cache cavity 5 is 15mm, but it cannot be greater than 20 mm; the solid solution of gas generating agent and the water extinguishing agent is 0.06 g / ml.

[0039]The bottom portion of the pharmaceutical storage chamber 1 of the present embodiment is provided with a separator 8 isolates the drug storage chamber 1 to the cache cavity 5, and the water fire extinguishing agent is encapsulated in the drug storage chamber 1, and the separator 8 of the present embodiment is the wall. The active piston 81, the piston 81 processes the position of the position of the cavity with a groove, which is embedded with a high temperature seal in the recess, and a pressure relief hole is opened at the center of the piston 81, and is mounted on the pressure relief hole. There is a one-way pressure relief val...

Abstract

The invention discloses a water-based gas-push fire extinguishing method and device, which belong to the field of fire-fighting technology. The specific technical solution is to encapsulate the water-based fire extinguishing agent in a chemical storage chamber and isolate it from the gas-generating chamber filled with the gas-generating agent. The medicament storage chamber is at the gas outlet end of the gas generating chamber. After the gas generating agent is ignited, it gathers in the buffer chamber. The high-pressure airflow enters the chemical storage chamber to heat up part of the water-based fire extinguishing agent to vaporize and spontaneously pressurize. At the same time, the high-pressure airflow generated by the gas-generating agent acts as the power source of the fire extinguishing agent to push the fire extinguishing agent to spray outwards, and spray the fire to the fire site. The fire extinguishing method and device of the present invention are safe in use, simple in structure, convenient to carry and transport, have high fire extinguishing efficiency, and have little environmental pollution.

Description

Technical field[0001]The present invention belongs to the field of fire protection, and in particular, the present invention relates to a water system gas push fire extinguishing method and apparatus.Background technique[0002]The fire extinguisher is an indispensable device that has occurred, which can effectively suppress the fire, eliminate the fire at the beginning. Now the fire extinguisher is mainly divided into a dry powder fire extinguishing agent and aquatic fire extinguisher, in which the dry powder fire extinguisher has higher air pressure, it is easy to happen, and the fire extinguisher is inverse, and the possibility of leakage, more serious, may sometimes be leaked The fire extinguisher cannot be used normally when fire extinguishing, causing unexpected losses to the family. The environment is seriously polluted during use. The water fire extinguisher is easy to clean because of its non-toxic and non-polluting fire extinguisher. Therefore, the market is more popular. Ho...
