Tianjin Longxing: provide dynamic hybrid core equipment for large flow fire fighting foam fire fighting operations
In major fire scenarios such as airport oil depot, petrochemical tank farm, offshore platform and urban tunnel, the fire extinguishing efficiency of fire foam directly depends on the online mixing quality of water, foam concentrate, nitrogen/compressed air three-phase media. Under the conditions of liquid-liquid gas three-phase homogenization, large flow conditions, long-distance transportation, etc., traditional venturi, pressure proportional mixer and balanced proportional mixer generally have pain points such as poor proportional accuracy, uneven bubble size, low stability of foam, and slow emergency response. Tianjin Longxing NDM series dynamic mixer provides high-intensity, low energy consumption, stable and reliable engineering solutions for large flow fire fighting foam fire fighting operations with high shear of stator and rotor+millisecond level three-phase homogenization+industrial level continuous operation.
Dynamic mixer: large flow foam fire extinguishing for airport, petrochemical and offshore platforms
In major fire scenarios such as airport oil depot, refining tank farm, offshore FPSO, LNG ships, the demand for fire foam is a triple superposition of “large flow rate+high intensity+long-distance transportation”. Under the condition of large flow, the mixing strength of traditional proportional mixer decreases, the bubble particle size is uncontrollable, and the foam is easy to collapse during pipeline transportation, which directly affects the fire extinguishing time, fire resistance time and coverage rate. The NDM series provides core process equipment for key scenarios such as high shear forced homogenization
Liquid liquid gas three-phase millisecond level homogenization: water, foam liquid (1-6%), nitrogen/air are evenly mixed in millisecond level, the bubble size distribution is narrow, the stability is high, and the foaming ratio and 25% liquid separation index are directly improved
Stable operation under high flow conditions: Suitable for single machine flow rates of 50-200 m ³/h, with a stable proportional accuracy of ± 0.5% throughout the entire flow range, completely solving the pain point of accuracy degradation of traditional proportional mixers under high flow rates
Long distance pipeline transportation foam stability: after dynamic mixing and homogenization, the foam will remain stable without foam attenuation within 1-3 km transmission distance, which is suitable for large operation radius scenarios such as ports, offshore platforms, LNG tank farms, etc
Industrial grade explosion-proof and anti-corrosion: ATEX/IECEx explosion-proof rating, optional 316L/duplex steel/Hastelloy for overcurrent components, suitable for high-risk environments such as oil tank areas and offshore platforms
Typical applications:
Airport oil depot: large flow foam extinguishing of hydrocarbon (B) fire and polar solvent (AR) fire in aviation oil tank farm
Petrochemical tank farm: liquid/underwater spraying foam fire extinguishing operation for large floating roof tanks and fixed roof tanks
Offshore platform/FPSO: large flow and high expansion foam extinguishing of offshore oil platform, suitable for marine environment
LNG ship/tank: deck/cargo tank foam covering of LNG tank farm and LNG power ship
Dynamic mixer: high expansion foam fully submerged fire extinguishing in tunnel and underground space
In urban road tunnels, subways, utility tunnels, underground parking lots, underground commercial streets and other confined spaces, the fire spread quickly, smoke exhaust is difficult, and the pressure of personnel evacuation is high. It is required that the fire foam can be completely submerged, quickly covered, and stably extinguished in a very short time. High expansion foam extinguishing is the preferred scheme for such scenarios, but it puts forward extreme requirements for the foaming quality, starting speed and long-distance transportation stability of the mixing equipment. NDM series provides professional solutions for continuous production of high expansion foam:
Continuous production of high expansion foam: the expansion ratio is 200-1000 times adjustable, the bubbles are dense and uniform, and the large space can be fully submerged in a few minutes
Cold state quick start: The equipment can be started from cold state to steady state in ≤ 60 seconds, meeting the “fast response” requirements under emergency conditions, without complex debugging on site, and can be started with one click
Mobile pry/vehicle integration: hybrid unit+proportional control system+electrical control cabinet+pry room highly integrated, can be loaded/towed, achieving “where there is fire, on-site deployment”
Multi media adaptation: compatible with proteins, fluoroproteins AFFF、 Anti alcohol (AR-AFFF), high expansion and other different foam concentrates support 1-6% full proportion online switching, and one equipment can deal with multiple fire types
Typical applications:
Urban highway tunnel: high expansion foam fully submerged fire extinguishing for long-distance and large section tunnels
Subway/underground station: high expansion foam rapid coverage of platform and section tunnel
Comprehensive pipe gallery/cable tunnel: efficient suffocation extinguishing of cable fires
Underground parking lot/commercial street: total flooding and fire extinguishing operations in large confined spaces
Industrial plant/energy storage power station: high coverage and cooling during the initial stage of thermal runaway of lithium batteries
Tianjin Longxing insists on taking the process value as the delivery standard, and uses the self-developed NDM series dynamic mixer to serve the fire fighting foam fire fighting operations in major fire scenarios such as airports, petrochemical, offshore, tunnels, and underground spaces, so as to help customers improve the fire fighting efficiency, ensure the stability of long-distance transmission and total flooding coverage, and support the localization upgrade of national emergency rescue equipment. Looking forward to building a more efficient and reliable fire safety system with you.
