Problems solved by technology

The pulse fire extinguisher is activated by rapid blasting powder, and there are safety hazards in its production, storage, transportation, installation, and use. At the same time, it cannot be used in places with people and inflammable and explosive places, which has certain limitations.
The patent for invention with the publication number CN102690156A discloses a solid nitrogen energy-storage driving drug. This drug generates gas to drive the fire extinguishing agent to explode rapidly and shortly. The lack of follow-up propulsion causes the pressure in the fire extinguisher to increase rapidly, and the fire extinguishing agent sprays quickly. If the speed is too fast, there will be more fire extinguishing agent residue

Embodiment 1

[0019] Weigh 40 parts by weight of one or more of strontium peroxide and strontium nitrate, 10 parts of combustible agent, 2 parts of carbon powder, magnesium carbonate, calcium carbonate, and potash feldspar. A mixture. The adhesive of 2 is one or more combinations of phenolic resin, epoxy resin and acrylic resin. After mixing these components evenly, they are added to the mold and dried to form a drive block with a stable shape. The driver is installed inside the fire extinguisher. When the driver is ignited, gas is generated. The pressure inside the fire extinguisher increases. The gas generates driving force on the fire extinguishing agent, and the fire extinguishing agent is sprayed to extinguish the fire.

Embodiment 2

[0021] Weigh 80 parts by weight of one of strontium peroxide and strontium nitrate or a mixture of the two, and 20 parts of one or more mixtures of guanidine nitrate, guanidine aminonitrate, triaminoguanidine nitrate, and diaminoguanidine nitrate , 10 parts of one or more mixtures of carbon powder, magnesium carbonate, calcium carbonate, and potash feldspar, and 10 parts of the binder is one or more combinations of phenolic resin, epoxy resin, and acrylic resin. After mixing these components evenly, they are added to the mold and dried to form a drive block with a stable shape. The driver is installed inside the fire extinguisher. When the driver is ignited, gas is generated. The pressure inside the fire extinguisher increases. The gas generates driving force on the fire extinguishing agent, and the fire extinguishing agent is sprayed to extinguish the fire.

Embodiment 3

[0023] Weigh 50 parts by weight of one of strontium peroxide and strontium nitrate or a mixture of the two, 15 parts of one or more mixtures of guanidine nitrate, guanidine aminonitrate, triaminoguanidine nitrate, and diaminoguanidine nitrate , 6 parts of one or more mixtures of carbon powder, magnesium carbonate, calcium carbonate, and potash feldspar, and 6 of the binder is one or more combinations of phenolic resin, epoxy resin, and acrylic resin. After mixing these components evenly, they are added to the mold and dried to form a drive block with a stable shape. The driver is installed inside the fire extinguisher. When the driver is ignited, gas is generated. The pressure inside the fire extinguisher increases. The gas generates driving force on the fire extinguishing agent, and the fire extinguishing agent is sprayed to extinguish the fire.

Abstract

The invention discloses a gas producing agent for a fire extinguisher. The gas producing agent comprises, by weight, 40-80 parts of a strontium salt oxidant, 10-20 parts of a combustible agent, 2-10 parts of an additive which is a mixture of one or more of carbon powder, magnesium carbonate, calcium carbonate and potassium feldspar. The strontium salt oxidant is continuously reacted with the combustible agent, wherein the carbon in the additive also participates in the reaction to provide continuous pushing force for a fire extinguishing agent, thereby improving fire extinguishing effect. One part of the fire extinguishing agent in the fire extinguisher, under the effect of air pressure, is pushed out by pressure, and the other one part is siphoned and is entrained out by air flow under the effect of subsequent air flow, thereby reducing residue of the fire extinguishing agent and improving the fire extinguishing effect.

Description

Technical field [0001] The invention relates to a fire extinguisher, in particular to a gas generating agent for the fire extinguisher. Background technique [0002] In the prior art, a pulse fire extinguisher with a rapid blasting powder built into the fire extinguisher is used. At the same time, the fire extinguisher is required to be designed with a blast hole or a container that uses fragile materials as the extinguishing agent. The fire extinguishing agent and the container are blasted open at the same time, so that the fire extinguishing agent rapidly diffuses under the action of the explosive power and shock wave to achieve the effect of fire fighting. Impulse fire extinguishers use rapid blasting gunpowder to start, and their production, storage, transportation, installation, use and other processes have hidden safety hazards. At the same time, they cannot be used in places with personnel and inflammable and explosive places, which has certain limitations. The invention ...
