High-speed through-wall fine water mist fire-extinguishing method

Abstract

The invention relates to a high-speed through-wall fine water mist fire-extinguishing method. The method is characterized by comprising the steps that: 1) a through-wall ejector can instantaneously realize high-speed movement and penetrate a wall; and 2) after the ejector penetrates the wall, a front nozzle of the ejector ejects high pressure fine water mist. Specifically, the step 1) is realized by the following way that: the through-wall ejector adopts a structural form similar to that of a hydraulic cylinder, the high-speed jet inlet of the through-wall ejector is connected to a high-pressure pump source, and a high-pressure accumulator and a sequence valve are disposed between the high-speed jet inlet of the through-wall ejector and the high-pressure pump source, the high-pressure accumulator gradually accumulates high pressure water with certain pressure and flow and when the pressure increases to the opening pressure of the sequence valve, the sequence valve can be opened. The method provided in the invention can realize through-wall fire-extinguishing without needing firefighters to enter a fireground, so that safety of the firefighters is effectively protected and large area destruction of walls or windows is not needed. Thus, the fire in an enclosed space within a building can be isolated from the outside air, and under the dual-fire-extinguishing mechanisms of high efficiency cooling and fast suffocation of high pressure fine water mist, the fire can be rapidly extinguished.

Description

technical field [0001] The invention relates to a high-speed wall-penetrating fine water mist fire extinguishing method, in particular to a method for using high-pressure spray to penetrate a wall and high-pressure fine water mist fire extinguishing. Background technique [0002] When a fire breaks out in a building at present, the large flow water gun or foam gun used by the fire brigade is mainly used to extinguish the open fire outside the building. When a fire breaks out inside a building, firefighters usually directly break through doors or windows to enter the building to rescue people and put out the fire, which is very dangerous. If there is no one in the building, the general firefighters will choose to break the door or window and spray water from the outside to the inside of the building, but this method is likely to cause danger when the door or window is broken. A large amount of air from the outside enters the building, so that the combustion can obtain more o...

If there is no one in the building, the general firefighters will choose to break the door or window and spray water from the outside to the inside of the building, but this method is likely to cause danger when the door or window is broken. A large amount of air from the outside enters the building, so that the combustion can obtain more oxygen, so that fire fighting and rescue are more difficult
