46. The pipeline 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 pipeline 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 tungsten inert gas (TIG) welding.

47. High-pressure fine mist pump set (water supply unit) system composition: 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 of the cable wires to the common terminal.

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

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

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

50. High-pressure fine water mist open system working principle: Upon detecting a fire signal, the fire alarm control main unit transmits the signal to the electric ball valve in the pump group control cabinet and the electric ball valve in the zone control valve box. The high-pressure plunger pump automatically starts up, and the electric ball valve in the zone control valve box opens. The high-pressure water then forms a mist through the pipeline and nozzle for fire suppression.

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

52. Working Principle of High-Pressure Fine Mist Closed System: Under the normal working condition, the fine mist system maintains a certain pressure within the pipeline from the pump group outlet to the control valve box. When the pipeline pressure drops and is lower than the set starting pressure of the pressure regulator pump (1Mpa), the pressure regulator pump starts, keeping the system pipeline pressure stable at (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 master unit transmits the signal to the pump group control cabinet. The high-pressure plunger pump starts, and the electric ball valves within the section control valve box are opened. The entire pipeline is filled with high-pressure water. Once the glass ball of the closed-loop spray head reaches the action 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 sends out a discharge signal, and upon receiving this feedback signal, the main unit联动ly activates the spray indicator light.

55. Automatic startup 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 fire detector's address and then sends a control signal to initiate the fire extinguishing system. This activates the high-pressure plunger pump and opens the corresponding section 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 by forming a misting effect through high-pressure fine mist nozzles, producing fine mist to extinguish fires.

57. Manual Electric Start for High-Pressure Fine Mist System: Remote Start: When a fire is detected, before the fire detector activates, the electric valve button on the corresponding zone control valve box at the remote fire control center can be used to start the zone valve, thereby initiating the system. The pump will automatically start to supply water for fire extinguishing.

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

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

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

61. Fire Extinguishing Mechanism of High-Pressure Fine Water Mist: Rapid Cooling and Local Asphyxiation—Advanced dual-action fire extinguishing mechanism: Water is emitted from a nozzle of a special material, forming a mist with particle sizes ranging from 10 to 100 micrometers. With a smaller surface area, the mist vaporizes quickly upon contact with fire, expanding in volume by 1,700 to 5,800 times, absorbing a significant amount of heat, and rapidly reducing the temperature of the combustion surface; at the same time, the vaporized water forms steam, enveloping and covering the entire combustion area, causing the fire to suffocate 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 can absorb heat at a rate of approximately 300 kW for every 1 kg of fine water mist emitted, demonstrating its high heat absorption rate and strong cooling effect.

63. Suppression Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: Aspiration effect – upon heating, the fine water mist vaporizes and expands dramatically to 1,700 to 5,800 times its original volume, creating a dense cloud of steam that envelops the burning material. This forms a barrier that prevents fresh air from entering, thereby causing the combustion to cease due to oxygen deprivation.

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

65. Suppression Mechanism of High-Pressure Fine Water Mist Fire Extinguishing: The high-pressure fine water mist not only reduces smoke and dust but also washes away waste. This is due to the combustion residue, carbon particles, and harmful gases bonding with the fine water droplets, thus being washed away. Statistics show that in fire accidents, 70% of fatalities are not directly caused by the fire but by the smoke and toxic gases emitted at high temperatures.

66. The extinguishing mechanism of high-pressure fine water mist: Involves 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. This prevents the further generation of flammable gases and combustion materials. Additionally, due to the small size of the water mist particles, they do not disturb the liquid surface, causing splashes, thereby achieving the goals of extinguishing fires and preventing their spread.

67. Mechanism of High-Pressure Fine Mist Fire Extinguishing: Three-dimensional Movement—Explanation for Full or Partially Filling the Protected Area. During the atomization of high-pressure fine mist, some smaller diameter droplets do not travel solely in the direction of the jet. They generate lateral and upward movement within the upper space of the nozzle, allowing the fine mist to fully 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 three-dimensional fire extinguishing.

68. Explanation of High-Pressure Fine Mist Fire Extinguishing Mechanism: Reason for the ability to extinguish electrical fires and why high-pressure fine mist is non-conductive when extinguishing electrical fires: The droplet diameter is small (10-100 micrometers), and the spray is discontinuous, allowing it to remain suspended in the air for a long time. It takes a large quantity and a considerable amount of time for the mist to coalesce and condense, making it difficult to form a conductive continuous water flow or surface area on the electrode surface. Its resistivity is slightly lower than that of air.

Open Fine Mist Fire Extinguishing Systems use water as the medium, employing special atomizing nozzles to break water flow into fine droplets under specific pressure (usually 14Mpa) for fire extinguishing. This fixed fire protection system is characterized by its economy and wide application range, and has become a significant technology to replace Halon fire protection systems, with a promising future of application.
