Problems solved by technology

[0003] The above two types of fire extinguishers have shortcomings. The seals of the container and parts of the stored pressure fire extinguisher are easy to age, and it is easy to cause the stored gas to leak and cannot be used. Regular inspection and maintenance are required.
The non-storage explosive fire extinguisher is driven by the explosion of the powder bag to spread the fire extinguishing agent to extinguish the fire. Its production, storage, transportation, installation, use and other processes are all dangerous, and it cannot be used in places with personnel and inflammable and flammable fire extinguishers. Explosion site, with certain limitations

Abstract

The invention discloses a solid nitrogen energy storage driving drug. The drug comprises, by weight, 50-70 parts of neutral inorganic salt, 15-22 parts of plant extract containing high carbon, 1-5 parts of active metal powder and 5-15 parts of stabilizer. The solid nitrogen energy storage driving drug converted to inert driving gas by excitation of heat energy is used for driving extinguishant in a fire extinguisher directly, so that dangers caused by the explosive fire extinguisher during processes of production, storage, transportation, mounting, use and the like can be eliminated, safety of the fire extinguisher is improved, and application range is expanded. In addition, size of an extinguisher container is reduced effectively, cost of normal detection and maintenance is reduced, service life of the extinguisher is prolonged greatly, long-term driving and spraying of the extinguishant can be achieved, prohibition and fire suppression for a fire scene are achieved more effectively, and extinguishing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to an energy storage driving medicine for fire protection. Background technique [0002] At present, the existing fire extinguishers on the market are mainly divided into two types according to the driving technology. One type uses pre-injected gas pressure as the driving energy to drive the fire extinguishing agent, and directly drives the fire extinguishing agent to diffuse fire. This type is called stored pressure type. fire extinguisher. The other is to use rapid blasting powder packs to be preset in the fire extinguishing agent in the fire extinguisher. At the same time, the fire extinguisher is required to be designed with a blast hole or to use a fragile material as a container for the fire extinguishing agent. The fire extinguishing agent and the container are blasted at the same time, so that the fire extinguishing agent can be rapidly diffused under th...
