Embodiment Construction

[0024] Such as figure 1 As shown, when a fire occurs in the protected space of the system, the ambient temperature of the fire scene rises rapidly, and when the temperature-sensing probe in the magnetic induction generator 3 reaches a preset temperature, the magnetic induction generator 3 will output a start-up current. Under the action of electric starter 4, electric sparks are sprayed out, and the liquid carbon dioxide 2 stored in the external steel cylinder 1 is gasified rapidly after being subjected to the electric sparks, and the volume expands rapidly, so that the injection switch 5 in the steel cylinder is opened , after the injection switch 5 is turned on, gaseous carbon dioxide enters the fire extinguishing agent water storage tank 8 along the gas pipeline 6, and after the carbon dioxide is ejected from the water level probe 7, a part of the carbon dioxide is mixed with the fire extinguishing agent 9, and more carbon dioxide is injected at high pressure. The form of t...

Abstract

The invention relates to a dual-drive mixing fine water mist fire-extinguishing system, which comprises an external steel cylinder, liquid-state carbon dioxide, a magnetic induction generator, an electric starter, a steel cylinder ejection switch, a gas pipeline, a water level probe, a fire extinguishing agent storage tank, a fire extinguishing agent, a built-in fire extinguishing agent ejection pipeline, a water storage tank spraying nozzle switch, a pressure limiting protection valve, a base bracket, a fastening snapping ring, an external fire extinguishing agent ejection pipeline and a fine water mist spraying nozzle. According to the dual-drive mixing fine water mist fire-extinguishing system of the present invention, the high temperature gas generated after liquid-state carbon dioxide gasification is adopted as the power source, the liquid fine water mist and the gas carbon dioxide are adopted as the fire extinguishing medias, and the two fire extinguishing ways such as the gas fire extinguishing and the fine water mist fire extinguishing are used during the fire extinguishing, such that the defects that the gas fire extinguishing requires the sealed space and the fine water mist fire extinguishing can not bypass the obstructions and directly contact the combustion zone is overcome to a certain extent, the advantages of the two fire extinguishing ways are completely provided, and the defects of the two fire extinguishing ways are overcome, wherein the most significant characteristic such as the complete advantage providing and the defect overcome of the system of the present invention is distinguished from the previous single fire extinguishing way.

Description

technical field [0001] The present invention is a dual-drive mixed fine water mist fire extinguishing system. The fire extinguishing system uses the high-pressure gas generated after the gasification of liquid carbon dioxide as the power source, and uses liquid fine water mist and gaseous carbon dioxide as the fire extinguishing medium. The generated fine water The mist is sprayed in the form of two-phase flow. This system combines two fire extinguishing methods of fine water mist liquid fire extinguishment and carbon dioxide gas fire extinguishment. Background technique [0002] As a new type of fire extinguishing method, water mist fire extinguishing method has the advantages of environmental protection, safety, high fire extinguishing efficiency, convenient maintenance and wide application range. But the pump group type water mist fire extinguishing products used now are generally pipe network type, which need to be composed of high pressure water pump, water storage tank...
