Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?
Dust produced in the process of production of some factories and mines, especially the dust produced in the processing of some organic matters, will explode and burn under certain conditions.(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction.Such as effective ventilation and biological film, dust suppression technology, integrated dust suppression technology, dust removal measures, smoking and fire operations are prohibited. A pressure relief valve or other device is arranged in the outer shell of the equipment, and an explosion containment system is adopted. For factories with dust explosion hazards, the design must be strictly carried out according to the technical grade of explosion protection, and ventilation and dust removal systems shall be installed separately. Often wet cleaning workshop floor and equipment, to prevent dust flying and gathering. Ensure that the system has a good airtight, if necessary, in airtight containers or pipes in the flammable dust filled with nitrogen, carbon dioxide and other gases, in order to reduce the content of oxygen, dust suppression explosion.
Flammable dust is suspended in the air at an appropriate concentration to form dust clouds that are commonly called;All the solid matter which is fine powder is called dust. The dust that burns and explodes is called combustible dust; the dust floating in the air is called suspended dust; the dust deposited on the solid wall is called sedimentary dust.With explosive dust: metal (such as magnesium, aluminum); coal; grain (such as wheat, starch); feed (such as blood meal, fish meal); agricultural and sideline products (such as cotton and tobacco); forest products (such as paper powder, wood flour); synthetic materials (such as plastics, dyes).
The graphite powder will cause an explosion. The production of graphite products in the workshop by means of centralized collection and fire protection to avoid explosion.The combustible dust explosion, dust explosion limits in encountered heat (fire or high temperature), flame spread instantly throughout the mixing space dust, fast chemical reactions, while releasing large amounts of heat, resulting in high temperature and high pressure, the system of energy into mechanical energy and light and heat radiation, has a strong destructive power. In the dust explosion with aluminum powder, zinc powder, aluminum powder, grinding a variety of plastic powder, organic synthesis of drug intermediates, wheat flour, sugar, wood, dyes, bakelite ash, milk powder, tea powder, tobacco powder, coal dust, dust and other plant fibers to produce production and processing places.
