Wet Chemical Kitchen Fire Suppression System for Edible Oil Fires

Product Specification

Kitchen Hood Wet Chemical Fire Suppression System Kitchen Fire Protection

*** Description of Kitchen Fire Suprresion System

The specialized fire extinguishing agent for cooking oil is a specially formulated mixture of low-pH water and organic salts. It achieves rapid fire suppression by chemically reacting with cooking oil to generate a non-flammable foam layer, thereby cutting off the oxygen supply. This extinguishing agent is characterized by being non-toxic, odorless, non-polluting, and easy to clean, meeting the high standards of environmental protection and safety required in modern kitchens.

*** Components of Kitchen Fire Suprresion System

The kitchen equipment fire extinguishing device is a complete set of devices installed in high humidity and heat environments such as industrial kitchens, commercial kitchens, and civilian kitchens, including:

lFire extinguishing agent storage container components

lDriving gas storage container components, and their driving devices

lPipelines

lNozzles

lValves

lTemperature sensors

lControl devices etc.

*** Working principle of kitchen Fire Suprresion System

 ** Flame Detection and Activation

1. Thermal Fusible Metal Cable Release Device: When the oil pot on the kitchen stove catches fire, the intense heat from the flames will cause the thermal fusible metal cable release device to heat up and detach.

2. Thermal Detection System: Simultaneously, the thermal detection system will detect the flames or high temperature, triggering the release mechanism of the kitchen fire suppression system. During this step, the system pressurizes the fire extinguishing agent storage container and activates all auxiliary electric shut-off devices (such as gas shut-off valves) and alarm linkage devices.

** Fire Extinguishing Agent Release

1. Fire Extinguishing Agent Spray: Once the release mechanism is activated, liquid fire extinguishing agents (such as foam, dry powder, or other specialized agents) are sprayed through nozzles onto the surfaces of kitchen stove equipment, as well as inside the exhaust hood, grease filter, and exhaust ducts. These specialized agents can quickly extinguish flames in the oil pot and form a covering layer to suppress the combustion of oil vapors, thereby preventing re-ignition.

2. Type of Fire Extinguishing Agent: Some kitchen fire suppression systems use high-pressure gas to propel the fire extinguishing agent. In this case, a mechanical actuator pierces the high-pressure gas cylinder, releasing high-pressure gas into a pressure-reducing valve. The gas then enters the top of the fire extinguishing agent cylinder, pushing the agent through delivery pipes to the nozzles for spraying. 

** Cooling and Flushing

1. Water Spray Valve Activation: After the system's extinguishing agent is sprayed, the water spray valve on the system will automatically open after approximately 3 to 8 seconds.

2. Water Flow Flushing: Water flows through the fire extinguishing agent pipes and nozzles, rapidly cooling and flushing the oil and stove equipment surfaces, ensuring the fire source is completely extinguished and preventing re-ignition.

** System Reset and Inspection

1. Manual Reset: Some kitchen fire suppression systems require manual reset after extinguishing a fire, such as manually resetting the gas emergency shut-off valve to reopen.

2. System Inspection: After each use or periodically, conduct system inspections to ensure the device is in good working condition, the fire extinguishing agent is sufficient, and all components are tightly connected without leaks.
