Intelligent fire extinguishing system for tall building and fire extinguishing control method

Abstract

The invention relates to an intelligent fire extinguishing system for tall buildings and a fire extinguishing control method.The system comprises a central controller, a fire sensing and detecting module and a spraying fire extinguishing module, and the fire sensing and detecting module comprises a smoke detector and/or a temperature sensor; the spraying fire extinguishing module comprises a flame retardant storage tank, a fire-fighting water tank, a liquid mixing and pressurizing assembly, a spraying pipeline and a spraying head, the flame retardant storage tank and the fire-fighting water tank are arranged on the top of the high-rise building and/or in a refuge storey, the spraying pipeline extends into a corridor and each room of the high-rise building, and the spraying head is arranged on the spraying pipeline; and the liquid mixing and pressurizing assembly can mix a liquid flame retardant in the flame retardant storage tank and water in the fire-fighting water tank in proportion. The fire extinguishing system has the advantages that when a fire occurs, the fire extinguishing system can automatically mix a fire retardant with fire-fighting water according to a certain proportion to form a fire extinguishing agent, so that the fire extinguishing capacity is greatly enhanced, the problem that some fire disasters are difficult to extinguish by only using water is solved, and the water consumption is greatly reduced; and the fire can be automatically monitored, confirmed and automatically sprayed to extinguish fire, and the safety is good.

Description

technical field [0001] The invention relates to the field of intelligent fire protection, in particular to an intelligent fire protection system for high-rise buildings and a fire extinguishing control method, in particular to intelligent fire protection in high-rise rooms of super high-rise buildings. Background technique [0002] Due to the continuous acceleration of urbanization, the shortage of urban housing land, coupled with the catalytic effect of some landmark buildings, the current ordinary housing is about 50 stories, with a total height of more than 150 meters, and currently the highest fire ladder in China is only 101 Therefore, the limit height of fire rescue is currently within 100 meters, and fire fighting above 100 meters needs to rely on the building itself to be equipped with corresponding systems. It is quite difficult to supply fire water for buildings with a height of 150 meters. In order to reduce the pressure of water pipes, they are all raised to the ...

AI Technical Summary

Problems solved by technology

It is very difficult to supply fire water to buildings with a height of 150 meters. In order to reduce the pressure of water pipes, they are raised to the roof through multi-stage water pumps. For some super high buildings with a height of more than 500-600 meters, it is even more difficult to supply fire water.

In addition to the difficulty of fire-fighting and water supply in high-rise buildings, when oil, electrical appliances, flammable cotton fabrics, etc. are on fire, simple water extinguishing not only consumes a lot of water but also often fails to meet the requirements

In addition, when a fire occurs, it is the easiest to extinguish at the beginning. If it can be found in time and accurately, it can be solved with a small amount of water or fire extinguishing agent and the loss is small. Therefore, it is necessary to combine intelligent vision or sensor systems, intelligent monitoring, Make timely and accurate judgments to avoid the spread of fire. The existing intelligent monitoring system that realizes this function has problems such as inaccurate fire identification or untimely triggering.
