The dust generated in the production process of some factories, especially the dust generated in the processing of certain organic matter, can cause explosive combustion accidents under certain specific conditions. Laser dust extractor manufacturer.

Research results at home and abroad show that there are generally three conditions: (1) Combustible dust is suspended in the air of appropriate concentration to form a dust cloud; (2) There is sufficient air and oxidant; (3) There is a fire source or strong vibration and friction. It is generally believed that as long as the explosive dust meets the conditions (1) and (2), it means that an accident may occur. laser engraver 4060 manufacturer

The formation and development process of powder explosion: a large amount of powder and dust produced in closed industrial equipment are mixed with oxygen in the air. If the proper concentration is reached, if a spark is generated, it will develop from a spark into a small fireball. If it is not suppressed, it will develop from a small fireball to a large fireball, accompanied by high temperature and high pressure. When the pressure rises to a certain level, exceeding the compressive strength of the equipment, an explosion will occur. In this process, the increased pressure will produce shock waves, and the propagation speed of the shock waves is much greater than the flame propagation speed. laser engraver 4060 fume extractor for strong odor

Using this principle, the sensor of the explosion suppression system can detect the shock wave in time. When the flame has no time to develop into an explosion, the launcher sprays an explosion suppressant (sodium bicarbonate) to spray the flame to prevent the small fireball from evolving into a large fireball or even an explosion, which may damage the equipment and even endanger personal safety.
