Description

technical field

[0001] The invention relates to a device for producing CO2, in particular to a fire extinguishing system for continuously producing CO2 gas through a chemical method. The invention also relates to a method for producing CO2 using the device. Background technique

[0002] The CO2 fire extinguisher used in the prior art mainly uses the CO2 high-pressure gas storage cylinder as the CO2 gas source to extinguish the fire. Its disadvantages are limited gas storage, high pressure danger, and inconvenient use. To extinguish coal spontaneous combustion fires in coal mines, fuel oil waste gas fire extinguishing and high-pressure separation nitrogen mechanism nitrogen fire extinguishing are commonly used at present. Its common disadvantage is that the inert gas used for fire extinguishing contains oxygen, which is unsafe, and the temperature of the inert gas is high, the safety performance is poor, it is inconvenient to use, it takes labor and materials, high energy co...
