46. The pipe network system of the high-pressure fine water mist fire extinguishing system utilizes stainless steel pipes (304) with anti-corrosion capabilities, as rusting can lead to the clogging of the nozzles by rust deposits on the pipe, resulting in system failure. The cleanliness of the pipe network system is crucial for the high-pressure fine water mist fire extinguishing system; hence, rigorous flushing, pressure testing, and blow cleaning must be conducted after the pipes are installed. All pipes are焊接 using tungsten inert gas (TIG) welding.

47. High-pressure fine mist pump set (water supply unit) system composition: consists of fine mist nozzles (open, closed), filters, zone control valve sets (boxes), water tanks, and stainless steel pipelines, etc.

48. High-pressure fine mist pressure switch:

Loosen the top screw of the pressure switch and remove the cover.

2. Connect one cable wire to the common terminal.

3. Connect the other cable wire to the normally open contact.

4. After wiring is complete, secure the cover and tighten the screws to restore to its original state.

49. High-pressure fine mist open system working principle: In the quasi-operational state, the fine mist system maintains a certain pressure in the pipeline from the pump group outlet to the zone control valve box. When the pressure drops below the set start pressure of the pressure maintenance pump by 1 MPa, the pressure maintenance pump starts up, maintaining a stable pressure of (1-1.2) MPa in the system pipeline.

50. High-pressure fine mist open system working principle: Upon detection of a fire signal by the detector, the fire alarm control master unit transmits the signal to the electric ball valve within the pump group control cabinet and the divisional control valve box. The high-pressure plunger pump automatically starts, and the electric ball valve in the divisional control valve box opens. High-pressure water forms a mist through pipes and nozzles to extinguish the fire.

51. Operating Principle of High-Pressure Fine Mist Open System: The pressure switch feedback system within the sectional control valve box initiates the release signal, after which the main unit receives the feedback signal and联动ly activates the spray indicator light.

52. Operating Principle of High-Pressure Fine Mist Closed System: In the standby condition, the fine mist system maintains a certain pressure in the pipeline from the pump group outlet to the control valve box. When the pipeline pressure drops and is lower than the 1MPa set starting pressure of the pressure maintaining pump, the pump is activated to keep the system pipeline at a stable pressure of (1-1.2) MPa.

53. High-pressure fine mist closed-loop system working principle: Upon detection of a fire signal by the detector, the fire alarm control main unit transmits the signal to the pump group control cabinet. The high-pressure plunger pump starts up, and the electric ball valves in the zone control valve box are opened. The entire pipeline is filled with high-pressure water. When the glass ball of the closed-loop nozzle reaches the activation temperature, the glass ball shatters, and the high-pressure water forms a mist through the nozzle for fire extinguishing.

54. High-pressure fine mist closed-loop system working principle: The pressure switch feedback system in the zoning control valve box triggers the release signal, upon which the main unit receives the feedback signal and联动ly activates the spray indicator light.

55. Automatic Start of High-Pressure Fine Mist System: Upon detection of a fire within the protected area, the fire detector senses the fire and sends a signal to the fire alarm controller. The fire alarm controller confirms the fire's location based on the detector's address and then sends a control signal to initiate the fire extinguishing system. This includes activating the high-pressure plunger pump and opening the corresponding zone control valves.

56. Automatic activation of high-pressure fine mist system: After the zone valve is opened, water in the system pipes quickly reaches working pressure (closed pre-action system waits for the closed spray head to sense the bursting temperature, then the glass ball automatically bursts), and sprays through high-pressure fine mist nozzles to create a misting effect, producing fine mist to extinguish fires.

57. High-pressure fine mist system manual electrical start: Remote start: When a fire is detected, before the fire detector activates, the electric valve button of the corresponding zone control valve box at the remote fire control center can be pressed to initiate the valve in the area, automatically starting the pump for water supply and fire extinguishing.

58. High-pressure fine mist system manual electrical start: Local start: When a fire is detected, the local section control valve box can be opened to activate the area valve by pressing the area valve control button for fire extinguishing.

Mechanical emergency start of high-pressure fine mist system: In the event of a failure in the fire alarm system, the handle on the zone valve can be manually operated to open the zone valve for extinguishing the fire. Note: Emergency start of the closed fine mist system can be achieved by smashing the glass ball of the closed spray head.

High-pressure fine mist is produced by professional equipment under low design working pressure, with a mist droplet cumulative distribution of Dv0.99 < 300μm on a plane 1m from the nozzle. High-pressure mist has functions such as cooling, humidifying, dust suppression, fire prevention, and landscaping, and can be used in industrial, breeding, planting, and entertainment fields.

61. Suppression Mechanism of High-Pressure Fine Water Mist: Rapid Cooling, Local Asphyxiation—Advanced Dual-Action Fire Suppression Mechanism: Water emitted from a nozzle made of a special material forms a mist with particle sizes between 10-100 micrometers, which has a smaller surface area. Upon contact with fire, it quickly vaporizes, expanding its volume by 1700-5800 times, absorbing a significant amount of heat and rapidly lowering the surface temperature of the combustion area; simultaneously, the vaporized water forms steam, surrounding and covering the entire combustion area, leading to asphyxiation due to lack of oxygen.

62. The fire extinguishing mechanism of high-pressure fine water mist: The heat absorption is calculated based on the latent heat of 100℃ water evaporation at 2257 kj/kg. Each fine water mist nozzle absorbs heat at a rate of approximately 300 kw per kilogram of mist sprayed, illustrating its high heat absorption rate and strong cooling effect.

63. Suppression Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Aspiration effect – when the fine water mist is heated and vaporizes, it expands dramatically to 1,700~5,800 times its original volume, creating a dense cloud of steam around the burning material. This forms a barrier that blocks the entry of fresh air. This deprivation of oxygen causes the burning material to cease combustion.

64. Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: After the fine water mist evaporates, the resulting steam quickly envelops the burning material, flames, and smoke, providing strong resistance to the radiant heat of the flames, preventing the spread of the fire.

65. Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: The high-pressure fine water mist also has a washing effect on smoke and debris. This is because the ash, soot particles, and harmful gases from combustion adhere to the fine water droplets and are washed away. Statistics show that in fire accidents, 70% of the deaths are not caused directly by the flames but by the smoke and toxic gases from the high temperatures.

66. Suppression Mechanism of High-Pressure Fine Water Mist: Wetting action — capable of extinguishing oil fires. The high-pressure fine water mist has a high particle velocity, allowing it to penetrate the surface of burning oil materials, wetting them and preventing the further production of combustible gases. Additionally, due to the small particle size of the fine water mist, it does not disturb the liquid surface, causing splashes, thus achieving the goal of extinguishing fires and preventing their spread.

67. Mechanism of fire extinguishing by high-pressure fine water mist: 3D movement – explanation for full or partial filling for fire extinguishing. During the atomization of high-pressure fine water mist, some smaller diameter droplets do not travel solely in the direction of the jet. They exhibit lateral and upward swirling movements within the upper space of the nozzle, allowing the fine water mist to fill the entire space of the protected area. The smaller the droplet size, the more intense the lateral transfer phenomenon. This is also referred to as 3D fire extinguishing.

68. Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Explanation of its ability to extinguish electrical fires, and why high-pressure fine water mist is non-conductive when extinguishing electrical fires: The droplet diameter is small (10-100 micrometers), and after being sprayed, it is discontinuous, capable of remaining suspended in the air for a long time. It requires a large quantity and extended time for the mist to coalesce and condense, making it difficult to form a conductive continuous water stream or surface area on the electrode surface. Its resistivity is slightly lower than that of air.

69. An open-type fine water mist fire extinguishing system uses water as the medium and employs special atomizing nozzles to break the water flow into fine droplets under specific pressure (usually 14Mpa) for fire suppression. It is a fixed fire protection system characterized by economy and broad application scope, and has become a significant technology replacing Halon fire suppression systems, with a promising future in various applications.

70. Composition and Working Principle of High-Pressure Fine Water Mist: The fine water mist fire extinguishing system consists of a high-pressure fine water mist storage tank, a pump unit for the fine water mist fire extinguishing system (including a high-pressure main pump, a high-pressure standby pump, a pressure regulator pump, a control cabinet for the pump unit, an inlet solenoid valve, an inlet filter, and a regulating tank), a water supply system, a water supply network, a group of zone control valves for the fine water mist fire extinguishing system, fine water mist nozzles, high-pressure fine water mist pipes, and a fire detection and alarm system.
