Abstract

The invention discloses a method for extinguishing fire by using flue gas, which comprises the following steps of: 1, collecting the stored flue gas: compressing the flue gas exhausted to a chimney by a boiler into a mobile gas storage tank or a fixed gas storage tank by using an air compressor, wherein the output end of the fixed gas storage tank is communicated with a gas pipeline of a user side through a building gas pipe network; 2, collocating an air respirator for emergency escape of a wearer indoors; 3, inflating gas to the room to extinguish fire: when a fire disaster happens, automatically opening a pipeline valve communicated with the fixed gas storage tank indoors by a trapped person to inflate the gas to the room to extinguish fire; supplying the flue gas to the fixed gas storage tank in time by a rescuer, or closing the pipeline valve at the output end in time according to the fire extinguishing condition; and 4, performing safe escape, namely the trapped person wears the air respirator and escapes the danger zone per se. By using the flue gas to extinguish the fire, the fire is extinguished quickly, the effect is good, articles are not damaged, building collapse accidents and personnel burn can be prevented, fire spread is effectively controlled, the escape time for trapped persons is prolonged, and the method has unique advantages of fire extinguishment of high-rise buildings.

Description

technical field

[0001] The present invention relates to a method of extinguishing a fire with flue gas. Background technique

[0002] The traditional fire extinguishing method is to use water spray to extinguish the fire. For high-rise buildings, when a fire breaks out, it is difficult for rescuers to enter the fire scene due to water and power outages. For the floors that can be sprayed with water, limited by various obstacles in the building, only a part of the water is directly sprayed on the burning objects, and the fire extinguishing efficiency is low. It was difficult for the trapped people to escape, and after the fire was extinguished, the accumulated water in the house caused the loss of property by immersion. Contents of the invention

[0003] The object of the present invention is to provide a method for extinguishing a fire with smoke, which can quickly extinguish the fire without damaging articles and can prolong the escape time of the trapped people. [000...

Embodiment Construction

[0016] The invention provides a method for extinguishing a fire with flue gas, the method comprising the steps of:

[0017] 1. Collect and reserve flue gas: Compress the flue gas discharged from the boiler to the chimney with an air compressor through the gas pipeline into the mobile gas storage tank installed on the transport vehicle or into the fixed gas storage tank installed near the building , the air pressure in the tank is kept within the specified pressure range; the output end of the fixed gas storage tank is connected with the gas pipeline at the user end through the building gas pipeline network. The fixed gas storage tank can be arranged underground, which saves people's living space, and its gas pipeline network is the same as the existing central heating pipeline network, which is a prior art. The mobile gas storage tank can provide flue gas for buildings on fire that are not connected with the fixed gas storage tank or temporarily supply gas to the fixed gas sto...
