Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishing devices, and more particularly to a fire extinguishing device with foam and dry powder. Background Art

[0002] The fire extinguishing device with foam and dry powder is a device that combines the two technologies of foam fire extinguishing and dry powder fire extinguishing. They each have different fire extinguishing principles and scope of application, but in some scenarios, combined use can provide a more comprehensive fire extinguishing effect. Foam fire extinguishing mainly produces foam to isolate the air and thus extinguish the fire. Foam can cover the surface of the burning object, forming a protective layer to prevent oxygen from entering. At the same time, the water in the foam evaporates and absorbs heat, which can also reduce the temperature of the fire scene. The dry powder fire extinguishing device mainly extinguishes the fire through the fire extinguishing agent in the dry powder. The dry powder fire extinguishing agent will decompose at high temperature to produce inert gas and powder, which covers the surface of the burning object, isolates the air and inhibits the combustion chain reaction.

[0003] However, in some special environments, it is necessary to use foam or dry powder to extinguish the fire according to actual conditions. For example, in flammable liquid storage places such as oil tank areas, both foam and dry powder fire extinguishing devices need to be equipped. However, when a fire actually occurs, the user may take the wrong fire extinguishing device and fail to effectively extinguish the fire, which is inconvenient for users to use.
