Problems solved by technology

[0002] At present, for fire extinguishers, high-pressure spray is used to extinguish the fire. Since the sprayed mist can effectively reduce the temperature of the fire source, it can effectively extinguish the fire. At the same time, in order to ensure the fire extinguishing effect, carbon dioxide, nitrogen, etc. are generally added to the water mist These gases can effectively isolate the fire source from the air, thereby improving the fire extinguishing effect and fire extinguishing ability. However, the current method of combining this gas with water mist is prone to waste of nitrogen and carbon dioxide when extinguishing a fire, because, After excessive injection of nitrogen and carbon dioxide, due to the effect of high-pressure water mist, nitrogen and carbon dioxide will be sprayed away by the sprayed water mist, which will cause nitrogen or carbon dioxide to fail to fully play its role of isolating the air, resulting in waste of gas and affecting Subsequent fire extinguishing effect and fire extinguishing ability

Abstract

The invention discloses a saving type high-pressure water mist fire extinguisher. A water-gas mixing control mechanism and a control mechanism are arranged, the water-gas mixing control mechanism enables high-pressure water supplied by a high-pressure water supply pipe to be mixed with nitrogen supplied by a high-pressure nitrogen tank, the control mechanism can adjust and control the proportion of high-pressure water and high-pressure nitrogen in the water-gas mixing control mechanism, so that when the aerial fog is sprayed, the proportion of water and nitrogen in the aerial fog sprayed by an aerial fog spraying nozzle is changed, therefore, the fire extinguishing capacity and effect are improved through the change of the proportion, and meanwhile nitrogen can be saved. The proportion of water to nitrogen in aerial fog sprayed by the aerial fog spraying nozzle is variable, contact between air and fire can be effectively isolated by adding the nitrogen, the temperature can be effectively reduced by utilizing the water fog, the fire extinguishing capacity and effect can be effectively improved, meanwhile, different control and operation can be achieved according to different fire extinguishing stages, and the purpose of saving nitrogen is achieved, and the fire extinguishing effect is improved.

Description

technical field [0001] Specifically, the invention is an energy-saving high-pressure fine water mist fire extinguisher, which relates to the field of fire extinguishers. Background technique [0002] At present, for fire extinguishers, high-pressure spray is used to extinguish the fire. Since the sprayed mist can effectively reduce the temperature of the fire source, it can effectively extinguish the fire. At the same time, in order to ensure the fire extinguishing effect, carbon dioxide, nitrogen, etc. are generally added to the water mist These gases can effectively isolate the fire source from the air, thereby improving the fire extinguishing effect and fire extinguishing ability. However, the current method of combining this gas with water mist is prone to waste of nitrogen and carbon dioxide when extinguishing a fire, because, After excessive injection of nitrogen and carbon dioxide, due to the effect of high-pressure water mist, nitrogen and carbon dioxide will be spra...
