Analysis of fire protection device integrated with environmental protection stove

Basic working principle and function of integrated stove

The integrated environmental protection stove integrates the range hood, the stove, the disinfection cabinet and the basket, and adopts the deep well side suction surrounding cavity. The smoking hole is around the top of the cavity. The hood is based on the micro-aerodynamic principle. With a capacity of more than 1,100 cubic meters, the peripheral air flows to the wellhead, creating a barrier to rising soot. The distance between the smoking hole and the pot edge is only 2 or 3 cm. When the soot is formed, it is sucked away by the hood. It belongs to the zero distance and sucks away the fumes. The soot does not spread and is quickly and completely discharged. The left, right and rear of the integrated stove are three. The side is equipped with a flue mouth, suitable for installation in different locations. In the middle is the control panel, and multiple functions are effectively controlled through the panel. An overflow hole is also designed in the cavity, the central outer ring probe is an ignition electrode (also called an ignition needle), and the inner side curved probe is called a gas sensitive probe (also called an ion detecting probe), and the gas sensing probe functions as an accidental flameout. Automatically cut off the air supply.

How the existing kitchen fire extinguishing device works

Due to the severe situation of the kitchen fire and the impact on the safety of life and property in China, Article 8.5.8 of the Code for Fire Protection of Building Design stipulates that the catering hood and the cooking part of the cooking operation room in the public building with a business area of ​​more than 500m It is advisable to install an automatic fire extinguishing device and an emergency automatic shut-off device should be installed on the gas or fuel pipe.

The current kitchen equipment fire extinguishing device is mainly based on the kitchen equipment water mist fire extinguishing system. It monitors the kitchen hood, exhaust pipe and stove and other equipment around the clock. When the cooking equipment in the kitchen equipment and the oil and grease are exposed to open flames, it will burn. When the huge heat is generated, the temperature inside the exhaust hood is rapidly increased. When the temperature is set to the operating temperature of the temperature sensing unit of the temperature sensing mechanism, the temperature sensor is automatically disconnected, and the mechanical control valve in the device is opened. The mechanical drive automatically turns off the fan, automatically cuts off the fuel supply and the kitchen equipment power supply. The device will automatically emit an audible and visual alarm signal and send an alarm signal to the fire control center. And through the control valve striker to break the high pressure gas cylinder diaphragm to release high pressure gas, driving the fire extinguishing agent storage bottle to spray a fine water mist to extinguish the fire.

Multi-functional modular integrated fire-fighting function integrates environmental protection stove to improve fire protection function from hardware

The congenital scientific design of the integrated environmental protection stove will make it the main choice for the commercial and civilian use of the kitchen in the future. The integrated environmental protection stoves currently popular in the market have fully equipped with the automatic cut off of the gas source, the electric leakage automatically cuts off the power supply, and automatically detects the air leakage. The odor gas exceeds the standard automatic suction and discharge, the time reminder function, and because of the more scientific manufacturing structure, the lower exhaust fume is more efficient, even the oil on the attached vertical wall will be diverted by gravity to the oil collecting at the bottom of the integrated stove. Inside the box, it is easy to clean and effectively avoids the accumulation of soot. Needless to say, like the traditional smoking hood, the exhaust pipe in the large kitchen needs professional cleaning, which is economical and safe. In addition, the use of the process can play a safety protection role, so that the safety factor is further improved, effectively avoiding the occurrence of kitchen fires.

Through the functional modular implantation, the existing kitchen fire extinguishing equipment, such as high temperature temperature probe, water spray contact, etc., can effectively and rationally utilize the inherent advantages of the integrated stove in design, and meet the specifications of the kitchen equipment fire extinguishing device. At the same time, by strengthening its fire prevention function, it further enhances the practicability and scientificity of the integrated stove in the kitchen fire prevention.
