Description
Technical Field
The invention relates to a suction type solid matter fire extinguishing device and a using method thereof.
Background
The three requirements of combustion are combustibles, temperature, oxidants. However, the requirement for combustion as described above does not mean that the combustion necessarily involves a flame, and the flame combustion requires additional conditions, that is: combustibles, oxidants, temperature and uninhibited chain reactions. Combustion must occur when the conditions are met. The fire extinguishing mechanism of fire extinguishing is to destroy the combustion condition which can propagate or generate flame and is to interrupt the combustion only by removing one of the necessary conditions of flame combustion, and finally the fire extinguishing effect is achieved. In practice, several basic methods of extinguishing fires have been summarized including: (1) an isolation fire extinguishing method; (2) extinguishing fire by suffocation; (3) a cooling fire extinguishing method; and (4) fire suppression.
The isolation fire-extinguishing method is to isolate or remove the burning substance from the surrounding unburned combustible substance, and to interrupt the supply of combustible substance, so that the combustion is stopped due to the lack of combustible substance. The specific method comprises the following steps:
1. combustible, inflammable, explosive and combustion-supporting articles near the fire source are removed;
2. closing valves of the combustible gas and liquid pipelines to reduce and prevent combustible materials from entering the combustion zone;
3. trying to block the scattered flammable and combustible liquid;
4. and (4) dismantling the inflammable buildings adjacent to the fire source to form a space zone for preventing the fire from spreading.
Black smoke generally refers to visible aerosol generated by fuel combustion, and is a product of incomplete combustion of fuel, if carbon particles are not sufficiently combusted, unburnt carbon particles continue to rise along with heat flow, and leave flames to be cooled, so that carbon particles floating in air (namely, black smoke) are formed, namely, the black smoke contains solid particle carbon particles which can pollute users, and meanwhile, the black smoke is called the black smoke because the carbon particles are black, so that smoke with other colors such as yellow smoke, red smoke and the like also exists. They are the same in that the high-temperature gas generated by combustion contains solid particles, and when the temperature of the high-temperature gas is lowered, the solid particles will not rise with the cold flow but will move downward under the action of gravity.
The existing fire extinguishing device mostly adopts the principle of the suffocation fire extinguishing method to extinguish fire, the fire extinguishing device adopting the principle of the isolation fire extinguishing method is not many, the fire extinguishing device adopting the principle of the isolation fire extinguishing method to extinguish the fire of solid matters is less, and the device adopting the isolation fire extinguishing method to keep away from fire extinguishing in the prior art often directly and roughly extracts combustion-supporting gas from the vicinity of the burning solid matters, but does not treat the extracted gas, thereby leading the extracted gas to possibly burn nearby users, and simultaneously, the extracted gas contains solid particles generated by burning and can also pollute the users.
