46. The pipe network system of the high-pressure fine water mist fire suppression system uses stainless steel pipes (304) with rust resistance, as once rust occurs, the rust deposits in the pipeline can block the nozzles, leading to system failure. The cleanliness of the pipe network system is crucial for the high-pressure fine water mist fire suppression system, thus, after the pipeline installation, it must be strictly flushed, pressure tested, and swept. All pipes are焊接 using the tungsten inert gas (TIG) welding method.

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.

3. Connect the additional cable to the normally open contact.

4. After wiring is complete, securely close the lid and tighten the screws to restore to original condition.

49. High-pressure fine mist open system working principle: In the standby condition, 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-up pressure of the pressure maintenance pump (1Mpa), the pressure maintenance pump starts up, ensuring the pipeline of the system maintains a stable pressure of (1-1.2) MPa.

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

51. High-pressure fine mist open system working principle: The pressure switch feedback system in the zone control valve box sends a discharge signal, upon which the main unit receives the feedback signal and联动activates the spray indicator light.

52. High-pressure fine mist closed-loop system working principle: 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 falls below the set start-up pressure of the pressure maintenance pump by 1 MPa, the pressure maintenance pump starts up to maintain a stable pressure in the system pipeline (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 a signal to the pump group control cabinet. The high-pressure plunger pump starts up, and the electric ball valves in the section control valve box open. The entire pipeline is filled with high-pressure water. When the temperature of the glass ball in the closed spray head 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 zone control valve box sends out a spray signal, upon receiving which the main unit联动activates the spray indicator light.

55. Automatic activation of high-pressure fine mist system: When a fire occurs within the protected area, the fire detector detects the fire and sends a signal to the fire alarm controller. The fire alarm controller confirms the area of the fire based on the address of the fire detector, then sends a control signal to activate the fire extinguishing system, starting the high-pressure plunger pump and opening the corresponding section control valves.

56. Automatic activation of high-pressure fine mist system: After the section 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 burst temperature, then the glass ball automatically bursts), and sprays fine mist through high-pressure fine mist nozzles to extinguish fires.

57. Manual Electrical Start for High-Pressure Fine Mist System: Remote Start: When a fire is detected, before the fire detector activates, the electric valve button of the corresponding zone control valve box can be started remotely from the fire control center, to initiate the zone valve. The pump will automatically start to supply water and extinguish the fire.

58. High-pressure fine mist system manual electrical startup: On-site startup: 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 suppression.

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

High-pressure fine mist is produced by professional equipment under low design working pressure, forming a mist with droplet accumulation distribution Dv0.99 less than 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. Mechanism of Fire Extinguishing by High-Pressure Fine Mist: Rapid Cooling, Local Asphyxiation — Advanced dual-action fire extinguishing mechanism: When water is ejected from a nozzle made of a special material, it forms a mist with particle sizes ranging from 10 to 100 micrometers, having a smaller surface area. Upon contact with fire, it vaporizes quickly, expanding its volume by 1700 to 5800 times, absorbing a significant amount of heat, thus rapidly lowering the temperature of the burning surface; simultaneously, the vaporized water forms steam, enveloping and covering the entire combustion area, causing the fire to suffocate due to oxygen deprivation.

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 for every 1 kg of fine water mist sprayed, demonstrating its high heat absorption rate and strong cooling effect.

63. The extinguishing mechanism of high-pressure fine water mist: Asphyxiation. After the fine water mist is heated and vaporized, its volume expands rapidly to 1,700~5,800 times. The steam tightly envelops the burning material, forming a barrier that blocks the entry of fresh air. This causes the combustion to be interrupted due to oxygen deprivation.

64. The fire extinguishing mechanism of high-pressure fine water mist: After the fine water mist evaporates, the resulting steam quickly envelops the burning material, flame, and smoke, effectively blocking the radiant heat of the flame, preventing its spread.

65. Fire Extinguishing Mechanism of High-Pressure Fine Water Mist: The high-pressure fine water mist not only has the effect of smoke and dust removal but also cleans smoke and debris. This is because the ash, carbon particles, and harmful gases from the combustion adhere to the fine water droplets, resulting in their removal. Statistics show that in fire accidents, 70% of the fatalities are not caused by direct burns but by the inhalation of high-temperature smoke and toxic gases.

66. The fire extinguishing mechanism of high-pressure fine water mist: Infiltration action – explanation for extinguishing oil fires. The fine water mist particles move at high speed, allowing them to penetrate deep into the surface of burning oil materials, wetting them. This prevents the generation of further flammable gases and materials. Additionally, due to the small size of the mist particles, they do not disturb the liquid surface, causing splashes, thus achieving the goals of extinguishing the fire and preventing its spread.

67. The fire extinguishing mechanism of high-pressure fine water mist: Three-dimensional movement – explanation of filling or extinguishing in full or partially. During the atomization of high-pressure fine water mist, some small-diameter droplets do not all move forward in the direction of the jet. The droplets produce lateral and upward eddy movements in the direction of the jet, entering 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 known as three-dimensional extinguishing.

68. Explanation of the fire extinguishing mechanism for high-pressure fine water mist: Reason why it is non-conductive when extinguishing electrical fires: The droplets are small in diameter (10-100 micrometers), and after being released, they are discontinuous, allowing them to remain suspended in the air for a long time. It takes a large volume and a significant amount of time for the mist to coalesce and condense. Consequently, it is difficult to form a conductive continuous water stream or surface area on the electrode, and its resistivity is slightly lower than that of air.

69. An open-type fine water mist fire extinguishing system utilizes water as the medium, employing special atomizing nozzles to disintegrate water streams into tiny droplets under specific pressure (usually 14 MPa) for fire extinguishing. It is a fixed fire extinguishing system characterized by economy and wide application, and has become a significant technology to replace Halon fire extinguishing systems, with a promising application prospect.

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