Throwing type carbon dioxide and dry powder bursting eruption fire extinguisher

Abstract

The invention relates to a throwing type carbon dioxide and dry powder bursting eruption fire extinguisher. The fire extinguisher comprises a dry powder extinguishing agent container and a sealing member of a blast hole (13), wherein the dry powder extinguishing agent container is used for containing a dry powder extinguishing agent; the blast hole (13) is formed in the wall of the container; the dry powder extinguishing agent container is connected with a carbon dioxide container for containing liquid carbon dioxide through a pressure-limiting valve; the pressure-limiting valve is ejected by carbon dioxide after the liquid carbon dioxide is evaporated due to heating and a pressure in the carbon dioxide container reaches a pressure-limiting valve opening value, so that carbon dioxide enters the dry powder extinguishing agent container; the sealing member is ejected by a mixture of carbon dioxide and dry powder extinguishing agent after carbon dioxide enters the dry powder extinguishing agent container and the pressure in the dry powder extinguishing agent container reaches a bursting eruption value, so that the mixture is erupted from the blast hole (13). Fire is extinguished by bursting eruption of the mixture of carbon dioxide and dry powder extinguishing agent in a throwing manner, and the fire extinguisher can be repeatedly used without causing a secondary disaster.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to a throwing type fire extinguisher. Background technique [0002] Existing dry powder explosion spray fire extinguishers are generally portable spray types, and the operator needs to carry the fire extinguisher to work near the fire source at the fire fighting scene. Therefore, when the fire source cannot be approached, or in a closed environment, the use of existing dry powder fire extinguishers will threaten the safety of firefighters. [0003] There is also a throwing explosive fire extinguisher, which can throw the fire extinguisher into the fire field. The fire extinguisher is heated and explodes, and the fire extinguishing agent is released to extinguish the fire. The cost is too high, and the explosion will bring uncontrollable secondary disasters, such as injuring or killing people in the fire scene, destroying property in the fire scene, etc. Contents of the invention [0004] T...

AI Technical Summary

Problems solved by technology

Therefore, in the case of being unable to get close to the fire source, or in a closed environment, the use of existing dry powder fire extinguishers will pose a threat to the safety of firefighters

[0003] There is also a throwing explosive fire extinguisher, which can throw the fire extinguisher into the fire field. The fire extinguisher is heated and explodes, and the fire extinguishing agent is released to extinguish the fire.
