Today we will talk about why the dust workshop should install led explosion-proof lighting. Several recent explosions in workshops and factories were caused by dust. Why does dust cause accidents?
The term dust explosion may seem remote to most people, but many people in their lives encounter environments prone to dust explosions and do not know why. For a simple example, a place where bread is produced will be full of dust. Can flour cause an explosion?
We consulted Mr. Liu, a citizen who has been engaged in the pastry processing industry for many years, and prepared experimental props under the guidance of Mr. Liu, including a hose, a plastic bottle (the upper part of which was cut), a candle, a lighter and a A small pile of flour, and prepare for the experiment.
We follow Mr. Liu's instructions to connect one end of the hose to the upper part of the plastic bottle and fill the plastic bottle with flour. After lighting the candle, blow air from the other end of the hose, and the flour filled in the plastic bottle will then float around. Two seconds later, the flour dust above the candle ignited instantly, and the fire was not small. Everyone felt incredible about the results of the experiment. "Flour is combustible. When it is usually stacked there, only the outer layer is in contact with the air. Because of the small contact area, it is more difficult to burn." Mr. Liu explained, "Once the flour becomes very fine dust flying in the air Every particle of dust can be in full contact with the air, and it can be quickly ignited when exposed to an open flame or high temperature and may explode. This phenomenon is called dust explosion." Mr. Liu said, therefore, his bakery’s Open flames are prohibited in the pastry processing area.
So, there are such high hazards in ordinary pastry processing places, let alone other dusty environments? The hazard of dust explosion is huge, so some people will doubt that dust may explode when it encounters high temperature. So how to choose the lighting lamp? Ordinary lighting in places prone to dust is definitely not able to meet the requirements, so everyone can choose LED explosion-proof lights to replace ordinary lighting. Although the power of 50W LED explosion-proof lamp is only, its luminous effect can reach 6000lm in actual use. In comparison, ordinary lighting lamp 80W may not achieve this luminous effect.
Generally, most workplaces prone to dust accidents will choose LED explosion-proof lamps. Explosion-proof lamps are used in dangerous places where flammable gas and dust exist. They can prevent possible arcs, sparks and high temperature ignition in the surrounding environment. Gas and dust, so as to meet the requirements of explosion-proof lamps. LED explosion-proof lamps are solid-state cold light sources, which have the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, and long service life. LED explosion-proof lamps use imported LED light sources, which can save about 90% of electricity compared with incandescent lamps with the same brightness. Compared with the current energy-saving lamps on the market, it can save electricity by about 60%. Moreover, the laboratory life of the LED explosion-proof light source is as long as 100,000 hours, which can realize long-term maintenance-free. The LED explosion-proof lamp has professional design, excellent structural design and surface sealing treatment, sturdy and durable, dust-proof and corrosion-proof. There can be no fluke for dust explosion in production and life. Choosing the right LED explosion-proof lamp can provide you with an extra layer Assure.
