Disclosed is a mixed jet flow fire extinguishing system, including a water spray nozzle and a powder spray nozzle. A water spray port of the water spray nozzle and a powder spray port of the powder spray nozzle do not overlap; super absorbent resin powder sprayed from the powder spray nozzle is externally mixed in the air with a water flow sprayed from the water spray nozzle. A powder spray direction A of the powder spray nozzle is inclined relative to a water flow spray direction B of the water spray nozzle. The technical bottleneck of using sodium polyacrylate resin powder as a fire extinguishing agent in the prior art is solved, so that the sodium polyacrylate resin powder can be smoothly and continuously sprayed into a fire, without blocking the powder spray port.

A fire extinguishing system of an air mobility vehicle includes a refrigerant flow line in which a refrigerant flows, and including a compressor, a condenser, a first expansion valve, and an evaporator, a fire extinguishing liquid flow line connected to the refrigerant flow line via a connection valve, and configured to spray a mixed liquid of a fire extinguishing liquid and the refrigerant, a mixing part connected to the fire extinguishing liquid flow line, and configured to mix the refrigerant and the fire extinguishing liquid, and a fire extinguishing liquid storage part configured to store the fire extinguishing liquid and to discharge the fire extinguishing liquid into a mixing space of the mixing part.

Disclosed is a fire suppressant system for an aircraft having: a source of a fire suppressant; a tubing system for delivering the fire suppressant to one or more predetermined locations; and a discharge nozzle disposed in the one or more predetermined locations, the discharge nozzle connected to the tubing system for distributing the fire suppressant in the one or more predetermined locations during a fire, the discharge nozzle including a plurality of nozzle heads including a first nozzle head with a first flow area and a second nozzle head with a second flow area that differs from the first flow area.

Provided herein is a fluid projecting platform. In some embodiments, the fluid projecting platform herein is configured for use in firefighting, crowd dispersion, agriculture or other related tasks.

A fire extinguisher includes a liquid fire extinguishing media, and first and second gases inside of a storage vessel at an operating pressure, and a discharge tube extending between a control valve and the fire extinguishing media. At least a portion of the first gas is dissolved in the fire extinguishing media. The control valve can be operated to control discharge of the fire extinguishing media via the discharge tube whereupon at least a portion of the second gas enters a flow of the fire extinguishing media via one or more holes in the discharge tube forming bubbles of the second gas in the flow of the fire extinguishing media. The fire extinguishing media exiting the control valve can pass through a nozzle which can causing first and second portions of the fire extinguishing media to collide forming a plume mist of the fire extinguishing media.

A fire suppression system that includes a non-rigid pouch, a quantity of suppressant, a quantity of gas, and a pressurized gas source. The non-rigid pouch that includes an exterior surface and an interior space. The quantity of suppressant, the quantity of gas, and the pressurized gas source is contained within said interior space. The pressurize gas source is configured to increase the internal pressure of the non-rigid pouch by injecting gas into the interior space. The non-rigid pouch is configured to rupture when the internal pressure exceeds a predetermined threshold pressure.

A fire suppression system includes a Coolant Infusion Spray Nozzle (CISN) and a Coolant Introduction Adapter Cap (CIAC). The CISN includes a water inlet and a coolant inlet. The CISN also includes a coolant infuser with infusion aperture(s) for injecting coolant into the water as it is bypassing the coolant infuser. This CISN generates a fire suppressing stream of coolant and water mixture. The CIAC supplies water and coolant to the CISN. The CIAC is coupled to a water source, and is also coupled to the CISN via hoses. The CIAC can includes an elbow for directing coolant toward the CISN.

A method as well as a liquid mixing system provide a liquid-foam mixture by mixing water with at least one additive. The liquid mixing system includes a water pressure source, an additive reservoir unit, an air compressor unit with a compressor and a drive device, a first and second mixing device, a discharging unit, and multiple different line networks for the respective media. The drive device is formed by a water engine or a water turbine, the water inlet of which is line-connected to the water pressure source.

A fire-suppression technology system has a tank with outlet and inlet orifices. A reservoir has a dispensing orifice. The tank receives water. The reservoir receives a quantity of powder adapted to be converted to a fire-suppressing fluid when mixed with water. A pump operatively couples the tank and the reservoir. A hose is operatively coupled to the pump. A spool is supports the hose. A primary path of travel constitutes a closed loop path between the tank and the pump and the reservoir to create a fire-suppressing fluid. A secondary path of travel constitutes an open path for dispensing the fire-suppressing fluid from the tank and the pump toward a region to be controlled.

A fire engine including a vehicle frame, a liquid nitrogen storage tank, a liquid nitrogen conveying pipeline, a gasification device, a plurality of electric valves, a water pipe adapter, a liquid nitrogen spray gun, and a mixed spray gun. The liquid nitrogen conveying pipeline includes a first pipeline and a second pipeline. The first pipeline connects the lower part of the liquid nitrogen storage tank, the gasification device, and the upper part of the liquid nitrogen storage tank sequentially in that order. The second pipeline connects the liquid nitrogen storage tank, an input end of the liquid nitrogen spray gun, and a first input end of the mixed spray gun. The mixed spray gun includes a first input end, a second input end, a liquid nitrogen nozzle, and a spray pipe. The spray pipe includes a contraction section, an expansion section, and an acceleration section.
