(2) and (2) injecting the fire extinguishing agent pre-configured in the step (1) into a fire extinguishing agent storage tank, closing an outlet valve of the storage tank, starting a fire extinguishing device control system, automatically starting a carbon dioxide pressurizing pump to inject carbon dioxide gas after the system detects that the pressure of the storage tank is low, replacing air in an upper space of the storage tank, closing a liquid supplementing port valve after 30 seconds of replacement, pressurizing the storage tank to 1.2MPa, automatically stopping, and controlling 1MP at normal temperature to dissolve 7L carbon dioxide gas by using 1L fire extinguishing agent, thus obtaining a finished canned water-based fire extinguishing agent.
Compared with the prior art, the invention adopting the technical scheme has the outstanding characteristics that:
the invention is harmless to human body and has long-acting antibacterial effect, low manufacturing cost and strong practicability.
The specific implementation mode is as follows:
the invention will be further illustrated by the following examples, which are intended only for a better understanding of the present invention and therefore do not limit the scope of the invention.
A water system extinguishing agent suitable for fine water mist comprises water, sodium chloride, a chlorine dioxide disinfectant or a chlorine dioxide activator and carbon dioxide gas, wherein a sodium chloride aqueous solution which is mixed by the water and the sodium chloride and contains 0.9% of sodium chloride is used as a main material, the chlorine dioxide disinfectant or the chlorine dioxide activator is added into the main material according to the weight ratio of 0.001-0.005% to form the water system extinguishing agent, the water system extinguishing agent is placed in a storage tank, and the carbon dioxide is dissolved by pressurizing according to the dissolving ratio of 7L carbon dioxide gas of 1L water system extinguishing agent, so that a finished water system extinguishing agent suitable for fine water mist is obtained.
Preferably, the aqueous sodium chloride solution is replaced by physiological saline.
Preferably, the chlorine dioxide disinfectant or chlorine dioxide activator is a chlorine dioxide effervescent tablet.
The preparation method of the water-based fire extinguishing agent suitable for the fine water mist comprises the following steps:
(1) adding 0.9% of analytically pure sodium chloride solid into a proper amount of distilled water or purified water, fully stirring and dissolving, adding 0.001% -0.005% of chlorine dioxide effervescent tablets, and standing for 20-25 minutes;
(2) and (2) injecting the fire extinguishing agent pre-configured in the step (1) into a fire extinguishing agent storage tank, closing an outlet valve of the storage tank, starting a fire extinguishing device control system, automatically starting a carbon dioxide pressurizing pump to inject carbon dioxide gas after the system detects that the pressure of the storage tank is low, replacing air in an upper space of the storage tank, closing a liquid supplementing port valve after 30 seconds of replacement, pressurizing the storage tank to 1.2MPa, automatically stopping, and controlling 1MP at normal temperature to dissolve 7L carbon dioxide gas by using 1L fire extinguishing agent, thus obtaining a finished canned water-based fire extinguishing agent.
