What is automatic fire extinguishing equipment for kitchen stoves?

Automatic fire extinguishing device for kitchen equipment, referred to as kitchen self-extinguishing device for short, code name: cmjs, is an effective self-starting fire extinguishing device for accidental fire in the oil pan of commercial kitchen stoves, which can quickly extinguish the fire in the oil pan and open the water flow valve at the same time, thus playing the role of cooling down and preventing re-ignition. It is a kind of equipment with more fire extinguishing options in commercial kitchens on the market at present.

Composition of fire extinguishing device for kitchen equipment

Nitrogen drive device: drive the injection of chemicals.

Edible oil fire extinguishing agent storage device: environmental protection fire extinguishing agent, which can extinguish the fire in 3-8 seconds.

Temperature sensing device: after the fire, the temperature rises rapidly, exceeding the normal temperature range, and the temperature sensing piece melts, triggering the fire extinguishing device.

Pipeline spraying device: spraying fire extinguishing agent, triggering water flow valve at the same time, and cooling after fire extinguishing.

Principle:

According to the characteristics of edible oil, it will ignite and burn at about 400 degrees Celsius, and the flame will quickly increase the temperature in the smoke range. When the temperature of the temperature sensor placed above the cooker in the hood reaches 183, the temperature sensor will melt, which will trigger the high-pressure nitrogen device to open through the transmission of steel wire, and the nitrogen bottle will release the pressure of 12Mpa, which will drive the fire extinguishing agent to spray out through the pressure reducing valve 1 of the device. The spraying speed is fast, and it only takes 1-2 seconds from the melting of the temperature sensor to the spraying of special drugs.

First, which scenarios apply?

Kitchen of schools, kindergartens, hospitals, shopping malls, factories, institutions, restaurants, hotels, restaurants, airports, stations and other canteens.

Second, the installation method and location

1. host: near the smoke hood in the back kitchen, hung on the wall.

2. Pipeline: connect the main engine of the kitchen fire extinguishing device with the nozzle in the hood.

3. Nozzle: installed in the smoke exhaust hood, connected with the pipeline, aiming at the cooker and the smoke exhaust duct.

Install the pipes and nozzles in the smoke hood connected with the kitchen fire extinguishing device.

4. Temperature sensing device: it is installed above the monitored cooker, and its height is generally 1.2m- 1.5m away from the cooker.

Third, how to choose the configuration of kitchen fire extinguishing device?

According to the actual situation of the kitchen

Configuration selection can only be higher than the actual situation, and it is forbidden to select configurations with protection scope lower than the actual situation!

The distinction of verb (verb's abbreviation) model

Common models of kitchen fire extinguishing devices are cmJS9- 1-CD and CMJS 18-2-CD. Many people don't know the meaning of the model, but they don't know that the model is scribbled casually and has a standard basis. According to product standards and technical requirements: GA498-20 12, CM is the code name of fire extinguishing device for kitchen equipment, which should be written in the first place. According to the type of equipment, S has water cooling function. If there is no water cooling, I won't write. The first set of numbers is the number of nozzles configured, the second set is the number of fire extinguishing agent containers, and the last set of letters is reserved for enterprise customization, which is generally abbreviated as the initials of enterprise brand name.
