Invent a new type of fire extinguisher by sucking fire into a fire extinguisher

Instead of the usual fire extinguisher, Japanese scientists have found a new solution to help fire in a timely manner while in space by sucking fire into a vacuum.

According to Newatlas , a mechanical engineering department at Toyohashi University of Technology, Japan has successfully developed a new type of fire extinguisher, promising to apply effectively on spacecraft. This type of bottle uses Vacuum Extinguish Method (VEM) , which allows the fire and flame source to be absorbed into a vacuum vessel, thereby helping to put out the fire more safely.

Fire is one of the greatest dangers for manned spacecraft or the system of ISS space stations, submarines, . The danger not only comes from heat, smoke, but also by substances Today's traditional fire will greatly damage the structure of the ship.

Few people know that submarine fire crews and ISS stations need to wear oxygen masks before handling fires, because even harmless gases to treat fires like CO ₂ can still cause crews. suffocated. Using water to extinguish fires in space is also an extremely reckless act.

That's why scientists have to find a new, more effective fire-fighting method to solve this problem. It is known that Toyohashi University of Technology cooperated with two other schools, Hokkaido and Shinshu, to study and create VEM .

Operating procedure of VEM method

This method almost completely reverses the way the fire extinguisher works. Instead of extinguishing the extinguisher, it will draw fire and flammable material into the vacuum chamber. The advantage of this method is to minimize the release of dangerous gases, isolate the flame from oxygen quickly, thereby speeding up the time to extinguish the fire and limit the use of unnecessary oxygen masks. .

According to lead researcher Yuji Nakamura, VEM is an extremely useful invention and promises to soon be applied to fire in many harsh and dangerous conditions. The study was published in the recent Fire Technology magazine.
