Device introduction

The hot aerosol fire extinguishing device produced by our company is a new type of environmentally friendly fire-fighting product. It uses S-type aerosol generators. All technical indicators have passed the "type inspection" of China's fixed fire extinguishing system and refractory component quality inspection center. One of the ideal replacement products for the device.

2. Working principle and characteristics

Working principle: After receiving the start signal of the fire alarm gas controller (panel), the aerosol generating agent in the device is activated, and the fire extinguishing gas (aerosol) is quickly generated. The gas is ejected from the nozzle of the device, completely flooding the protective area. To achieve the purpose of fire fighting.

Fire extinguishing mechanism: chemical fire extinguishing mainly interrupts the combustion chain reaction, and also has a certain suffocating effect.

Main features: The medicament is stored under normal pressure, with high safety performance; no pipe network is needed, easy installation and maintenance; no loss of atmospheric ozone layer, and it is a green product.

3.Main uses and scope of application

1. S-type hot aerosol fire extinguishing device is mainly used for fire extinguishing in communication, post and telecommunications, metallurgy, power, finance and other industries; it is suitable for extinguishing the following fires under relatively closed conditions:

a) Electrical fire in communication room, computer room, transformer (distribution) room, generator room, cable mezzanine, cable well, cable trench, etc.

b) Fires in various C-flammable liquid places such as diesel oil (except No.-35 diesel oil), heavy oil, transformer oil, lubricant oil, animal oil, vegetable oil, etc .;

c) Fires on the surface of flammable solid materials where flammable solid materials are produced, used or stored;

d) A gas fire that can cut off the gas source before extinguishing the fire.

2. S-type hot aerosol fire extinguishing device cannot be used to extinguish the fire of the following substances:

a) Chemicals (such as nitrocellulose, gunpowder, etc.) that can rapidly oxidize without air, and chemical substances (such as hydrazine, certain metal peroxides) that can decompose by themselves;

b) active metals (such as potassium, sodium, etc.), metal hydrides (such as potassium hydride, sodium hydride, etc.), strong oxidants (such as nitrogen oxide, fluorine, etc.) and substances that can spontaneously ignite (such as phosphorus)

c) Deep fire of combustible solid matter.

4.Safety warning

1. The user unit should set obvious warning signs in the following places, and the terms of the signs are suggested as follows:

a) Protected area: Warning! This is a S-type hot aerosol gas fire protection area. After hearing the on-site alarm, personnel should immediately withdraw;

b) At the emergency start button: Warning! Make sure there are no people in the protective area during emergency start.

c) Outside the protection zone: This protection zone is an aerosol gas fire protection zone.

2. According to the "Code for Design of Gas Fire Extinguishing System" (GB50370-2005): If it is used in a place where people work, a delay in spraying is required, and personnel must be withdrawn within the delay time;

3. According to the "Code for Design of Gas Fire Extinguishing System" (GB50370-2005): within 1.0m in front of the nozzle of the hot aerosol fire extinguishing system device, no equipment or appliances should be installed or stored within 0.2m of the back, side and top of the device. The user unit shall strictly abide by the implementation.

4. After the fire extinguishing agent is sprayed, a suspension system (aerosol) of solid particles in the air will be formed. The main fire extinguishing components such as metal salts and metal oxides will be in the form of solid particles, which will precipitate and adhere to the object after a long time. surface. After the aerosol is sprayed, the equipment should be cleaned in time to prevent pollution and damage to the equipment.
