Abstract: The present invention discloses a gas-powder separation three-phase jet flow fire monitor system, including a gas-powder separation three-phase fire monitor head, a filter, a nitrogen pressurization apparatus and a dry powder tank. The dry powder tank is connected to a gas-powder mixture inlet pipe of the gas-powder separation three-phase fire monitor head through a pipeline. A nitrogen outlet pipe of the gas-powder separation three-phase fire monitor head is connected with one end of the nitrogen pressurization apparatus through the filter. The other end of the nitrogen pressurization apparatus is connected with the dry powder tank. The present invention is simple in structure and convenient to use. A cyclone separation apparatus of a dry powder pipeline of the fire monitor may separate nitrogen from conveyed ultrafine dry powder to enable the ultrafine dry powder to be fully mixed with a water-based fire extinguishing agent, thereby reducing an atomization degree of jet flow and enlarging a range of the fire monitor. In addition, the separated nitrogen enters the dry powder tank for recycling after being pressurized by the pressurization apparatus, thereby reducing the fire extinguishing cost.
