Backpack type multiphase multi-agent combined fire extinguishing equipment for individual combat

Backpack type multi-phase multi-agent combined fire extinguishing equipment for individual combat comprises a backpack frame, a water-based fire extinguishing agent tank is vertically arranged in the middle of the back face of the backpack frame, a superfine dry powder tank and a carbon fiber high-pressure nitrogen cylinder are vertically arranged on the left side and the right side of the water-based fire extinguishing agent tank respectively, and the top of the carbon fiber high-pressure nitrogen cylinder is connected with a pressure hose through a valve. The pressure hose sequentially communicates with the top of the water-based fire extinguishing agent tank and the top of the superfine dry powder tank, and the tail end of the powder spraying pipeline and the tail end of the water agent spraying pipeline are jointly connected with a water-powder-gas combined spraying gun. High-pressure nitrogen is used as power, and the strong power of the high-pressure nitrogen can enable a three-phase-in-one fire extingu
