The fire extinguishing agent with it as the medium has good cleanliness. The National Institute of Standards and Technology (NIST) announced that the critical fire extinguishing concentration of 2-bromo-3,3,3-trifluoropropene to extinguish n-heptane fire is 2.6%, and the U.S. Environmental Protection Agency (EPA) announced that its atmospheric survival life value (ALT) is 0.014 years, and the ozone depletion potential (ODP) and greenhouse effect potential (GWP) are both 0. Because 2-bromo-3,3,3-trifluoropropene has the advantages of high fire extinguishing efficiency, stable insulation, low toxicity, no corrosion, and no pollution, it can be used in important production places such as computer rooms, communication rooms, substations, precision instrument rooms, generator rooms, oil depots, libraries, and databases.

[0003] 2-bromo-3,3,3-trifluoropropene fire extinguishing agent has strict requirements on water content, and the entry of external moisture and other impurities during canning should be avoided. Therefore, the present invention solves the canning and application problems of 2-bromo-3,3,3-trifluoropropene. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a 2-bromo-3,3,3-trifluoropropene canning system, which can achieve 2-bromo-3,3,3-trifluoropropene in a clean and dry environment without product leakage and strict quality control.

[0005] The objective of the present invention is achieved through the following technical measures: a 2-bromo-3,3,3-trifluoropropene canning system, comprising a cleaning, drying and cooling assembly and a fire extinguishing agent filling assembly, the cleaning, drying and cooling assembly and the fire extinguishing agent filling assembly being connected in sequence; the cleaning, drying and cooling assembly is used for internal cleaning and water vapor replacement of a 2-bromo-3,3,3-trifluoropropene fire extinguishing agent storage tank, and the fire extinguishing agent filling assembly is used for accurate weight filling of the fire extinguishing agent in the storage tank.

[0006] Furthermore, the cleaning, drying and cooling assembly includes a gas tank, a drying device, a high-pressure water pump, a gas pipeline and a high-pressure water pipeline. The other end of the high-pressure water pump provides high-pressure water for cleaning to the liquid storage tank through the high-pressure water pipeline. The drying equipment dries the inside of the liquid storage tank through the gas pipeline. The gas tank is connected to the gas pipeline to transport cooling gas to the liquid storage tank.

[0009] A method for filling a 2-bromo-3,3,3-trifluoropropylene fire extinguishing agent comprises the following steps: 1) Connect the liquid storage tank to the gas tank and the high-pressure water pipeline, start the high-pressure water pump, and evenly flush the liquid storage tank with high pressure through the high-pressure water pipeline; 2) High-temperature gas is transported to the inner cavity of the liquid storage tank to evaporate and dry the water vapor;

[0010] 3) After drying, the dry gas source or nitrogen is transported to the inner cavity of the liquid storage tank to reduce the temperature inside the liquid storage tank and replace the internal water vapor to enter the next process; 4) Place the liquid storage tank on the weight sensor and connect the pipeline. Set the required filling weight on the sensor, start the gas vacuum pump, evacuate the liquid storage tank, close it after reaching the required vacuum, adjust the nitrogen bottle pressure reducing valve to the required pressure, open the valve to automatically fill nitrogen, stop after reaching the specified pressure, start the gas vacuum pump again to evacuate, extract the gas after nitrogen replaces water vapor, start the liquid booster pump, and the booster pump fills 2-bromo-3,3,3-trifluoropropylene fire extinguishing agent into the liquid storage tank.
