According to the Building Design Fire Prevention Code GB 50016-2014 (2018 edition) 8.3.11 regulations
8.3.11 Restaurant or cafeteria with a dining room floor area of more than 1,000m2, the exhaust hood of the cooking operation room and the cooking parts should be equipped with automatic fire extinguishing devices, and gas or fuel piping should be Set up with automatic fire extinguishing devices linked to the automatic cut-off device.
See, the kitchen fire extinguishing equipment only for the area of more than 1,000 square feet above the restaurant cafeteria to do a clear requirement needs to be equipped for the general catering enterprises and institutions, and did not make clear provisions must be installed.
No clear requirements = do not have to install? NO
Restaurant cafeteria less than 1,000 square feet, there is no clear provisions for the installation, is not necessary to install?
The answer is no, once the fire, never because the area is too small and the fire is reduced. As the saying goes, water and fire, in front of the fire, everything is ashes! With the continuous development of the catering industry, people for cooking requirements is also more and more very high, a variety of cooking methods are also endless, but all changes are not the same, cooking is the fundamental food cooked, then can not be separated from the source of heat, whether it is an open fire or electric heat, there is a certain amount of safety hazards.
In recent years, due to improper operation of the catering kitchen caused by fire cases are common, light property damage, to bear the compensation, ten years of hard work, savings, savings of the family business, a return to the liberation of the former, and even the family property is not enough to pay; heavy casualties, may also need to bear civil or criminal liability, it is too late to regret.
In fact, 90% of the fire can be in the early stages of the fire through the correct method to extinguish, and most of the situation is the scene of a serious lack of awareness of the fire, can not make the right disposition in a timely manner, resulting in the fire continues to accelerate the spread of the fire, and miss the best time to extinguish the fire!
Kitchen equipment automatic fire extinguishing device, referred to as the kitchen self-extinguishing device, code: CM, is a commercial kitchen stove pot accidental fire effective self-starting fire extinguishing device, can do in the early stages of the fire 3-8 seconds to quickly extinguish the pot fire, synchronized with the opening of the valve of the flow of water, to play a cooling to prevent the recombustion of the effect. Is currently on the market for commercial kitchen fire fighting more choice of equipment and devices.
Kitchen equipment automatic fire extinguishing device composition:
Nitrogen drive device: drive agent injection; 158
Cooking oil fire extinguishing agent storage device: environmentally friendly cooking oil extinguishing agent, 3-8 seconds to extinguish the fire; 1097
Temperature sensing device: after the fire the temperature rises rapidly, exceeding the normal temperature range, the temperature sensing piece melted, triggering the fire extinguishing device; 5915
Pipeline injection device: spray extinguishing agent, while triggering the water flow valve, after extinguishing the fire cooling;
Kitchen equipment, automatic fire extinguishing device principle:
According to the characteristics of cooking oil, in 400 degrees Celsius or so will start a fire, the flame will make the upper stove within the temperature rises rapidly, when placed in the hood above the pot stove temperature of the temperature-sensitive piece reaches 183 °, the temperature-sensitive piece fuses, through the fire extinguishing device. When the temperature of the temperature-sensitive piece above the stove in the hood reaches 183 °, the temperature-sensitive piece fuses, and is passed through the steel wire guide, triggering the opening of the high-pressure nitrogen device, the nitrogen bottle releases 12Mpa pressure, and through the device decompression valve to drive the fire extinguishing agent for spraying, 1-3 seconds to extinguish the fire. The agent is sprayed quickly, from the temperature-sensitive piece of fusion, to spray the special agent only 1-2 seconds. After the fire extinguishing agent is sprayed to prevent recombustion, the equipment automatically starts the water jet, the second cooling.
Kitchen equipment installation of automatic fire extinguishing devices:
1, host: the back of the kitchen hood near the wall hanging installation
2, piping: connect the kitchen fire extinguishing device host and hood nozzle
3, nozzle: installed in the hood, connecting the piping, aligned with the pots and pans and the exhaust flue
4, temperature sensing piece of equipment: installed above the pots and pans to monitor, the height of the general height of the special agent. Monitoring of the pots and pans above, the height of the general distance from the pots and pans 1.2 meters - 1.5 meters
5, near the location of the installation of the host, reserved power supply and 4-point tap water interface
Kitchen equipment automatic fire extinguishing device configuration:
Equipment according to the different manufacturers, generally divided into a single-bottle group and a double-bottle group, the production and testing of equipment is strictly enforced by the "GA 498-2012 Kitchen Equipment Fire extinguishing device" production specifications;
Equipment configuration according to the actual situation of the construction site, in accordance with the equipment configuration standards for combination and matching, strictly prohibit the reduction of allocation!
Kitchen equipment automatic fire extinguishing device model differentiation:
Common model CMJS9-1-CD and CMJS18-2-CD, many people do not know the meaning of the model, the kitchen self-extinguishing device model is not just randomly written, there is a standard based on the product standards and technical requirements: GA498-2012, CM is the kitchen equipment fire extinguishing devices CM is the code name of the kitchen equipment fire extinguishing device, to be written at the forefront; according to the start-up mode is divided into mechanical start, code J, electric start, code D, according to the cooling mode of differentiation, S is a function with water cooling, if there is no water cooling, it is not written; the first group of figures is the number of configured nozzles, the second group of figures is the number of containers of extinguishant, and the last group of letters is left to the enterprise customization, generally for the initials of the abbreviated name of the enterprise brand.
Summary: kitchen fire extinguishers are like a piece of insurance, a piece of insurance that everyone thinks is useless, but who knows when the accident comes back? With a small amount of money, four or two is the meaning of the kitchen automatic fire extinguishing device!
