Background

The spontaneous combustion refers to the phenomenon that combustible substances are combusted by self-heating or external heat without the action of an external fire source in the air, and the spontaneous combustion of the substances is divided into self-heating spontaneous combustion and heated spontaneous combustion according to different heat sources. Under normal conditions, generally, the contact between combustible substances and air can generate a slow oxidation process, but the speed is slow, the separated heat is little, and meanwhile, the combustible substances continuously dissipate heat to the surrounding environment and cannot emit light like combustion. If the temperature rises or other conditions change, the oxidation process is accelerated, the precipitated heat is increased and accumulated after being not completely dissipated, and the temperature is gradually increased. When the lowest temperature at which such a substance burns, i.e., the ignition point of the substance, is reached, it will self-ignite, and the explosive substances that can form explosive mixtures with air fall into three categories: class I is mine methane; class II is explosive gas, steam or mist; the class III is explosive dust and fiber, flammable solid refers to solid with low ignition point, is sensitive to heat, impact and friction, is easy to ignite by an external fire source, burns rapidly, and possibly emits toxic smoke or toxic gas, the safety of the dangerous goods and the goods with unknown ignition points needs to be detected, the conventional spontaneous combustion detection device only monitors and detects static dangerous goods, and is single in function, and is not provided with an alarm and a fire extinguishing device, so that the use is unsafe.
