The word dust explosion may seem very far away to ordinary people, but in daily life, many people encounter environments prone to dust explosions and do not know why. To give a typical example, there is a lot of dust in the workshop for making toast. Can flour cause an explosion?
Mr. Liu, a citizen who has been in the noodle production industry for many years, was consulted, and with the help of Mr. Liu, the experimental props were equipped, including a plastic hose, a plastic bottle (the upper part was intercepted), a candle, a lighter and A small pile of flour, while doing pre-test preparations.
According to Mr. Liu's instructions, we connected one end of the plastic hose to the upper part of the plastic bottle and filled the plastic bottle with flour. After lighting the candle, blow air from the other end of the plastic hose to check, and the flour filled in the plastic bottle will fall around. A few seconds later, the flour dust above the candle ignited instantly, and the fire was very intense. Everyone finds it hard to believe the conclusion of the experiment. "Flour is flammable. When it is usually piled up there, only the outer layer is in contact with the air. Because the contact surface is small, it is difficult to ignite." Mr. Liu explained, "Once the flour turns into fine floating dust When in mid-air, every particle of dust can have enough contact with the air, and it can be ignited quickly and may explode in case of fire or sustained high temperature. There is a professional term for this situation called dust explosion.” Mr. Liu said that, therefore, open flames are prohibited in the processing areas of his bakery.
In that way, there is such a high level of damage in ordinary pastry production and processing sites, let alone other dust environments. Dust explosions are very harmful, so many people will doubt that smoke and dust may explode when they encounter continuous high temperatures So how to choose lighting fixtures? In places prone to dust, general lighting fixtures must not meet the standards, so you can choose LED explosion-proof lamps instead of general lighting fixtures. The luminous effect of 50W LED explosion-proof lamp can reach 6000lm in actual use. Compared with 80W general lighting fixtures, it cannot achieve this kind of luminous effect.
Most of the general places prone to dust accidents will choose LED explosion-proof lamps. Explosion-proof lamps are used in risky places where flammable gases and dust exist, which can prevent electric arcs, sparks and high heat that may occur in the internal structure of the lamp from igniting combustible lights in the surrounding environment. Non-toxic gas and dust, in order to meet the requirements of explosion-proof lighting. LED explosion-proof lamps are solid cold light lamps, which have the characteristics of high silver-to-electricity conversion efficiency, low calorific value, low power consumption, and durability. LED explosion-proof lights have a more professional design scheme, good overall design and surface sealing, durable, anti-fouling and anti-corrosion, and you can't have a fluke mentality for dust explosions in production activities. Choosing a suitable LED explosion-proof light can help you Bring an extra layer of protection.
