Description

Firefighting disaster prevention equipment with improved fire suppression efficiency}

The present invention relates to a fire-fighting disaster prevention device with improved fire suppression efficiency.

Generally, firefighting facilities such as fire extinguishers, sprinklers, fire alarms, and barriers are installed inside a building to extinguish a fire when it breaks out.

Meanwhile, fire-fighting facilities such as sprinklers are generally configured to receive fire-extinguishing water supplied from the outside through pipes and discharge it to the outside through a spray nozzle provided at the end. Through this configuration, fire-fighting water is delivered to the point where the fire occurred. It is configured so that it can be sprayed.

For example, a conventional firefighting facility is configured to discharge fire extinguishing water to the fire site through a nozzle provided when a fire is detected.

However, even in the same building, oil stored in an oil storage warehouse is difficult to extinguish with ordinary firefighting water in the event of a fire, and moreover, this matter was not taken into consideration at all in conventional firefighting facilities. In particular, oil fires are fragmented when they come into contact with firefighting water. As it spreads to the surrounding area, it causes great difficulty in extinguishing the fire.

Therefore, the need for technology to block firefighting water from being sprayed into the oil in the event of an oil fire while extinguishing fires using firefighting water in areas other than oil fires is greatly demanded in the relevant field.
