Closed coal storage yard lighting design

The closed coal storage yard covers the coal yard with a large-span steel frame structure and color steel plates to build a stable, safe and environmentally friendly building. Today\'s coal storage yards generally have three types of closed coal storage yards, open coal storage yards and semi-open coal storage yards. Due to environmental protection safety requirements and strict control of construction land, the way of loose coal has been replaced by closed storage methods, so the construction of closed coal storage has gradually developed in China in recent years.

Because the closed coal storage yard has many coal ash and is easy to start burning, the closed coal storage yard lighting should choose lamps that meet the requirements of explosion-proof, moisture-proof, dust-proof and anti-corrosion. On the light source of the lamp, high-color sodium lamp, metal halide lamp or LED lamp is used; the lighting circuit should be installed in accordance with the installation requirements of the explosion-proof lamp; the material and the junction box should be made of high-quality explosion-proof materials.

Due to the high requirements of the coal storage yard for a good lighting environment, the following points should be noted in the selection of lamps:

1. First, choose a series of safety lamps with national explosion-proof certification.

2, the light transmittance, illumination, life and protection level of the lamps should be clearly seen. Different protection levels have different requirements on the environment. When choosing, we must pay attention to it, and resolutely put an end to the inferior and cheap cottage products;

3. The luminous efficacy of the luminaire cannot change with fluctuations in voltage;

4. Whether the joint sealing treatment of the luminaire is perfect;

5. Whether the lamp can reduce the temperature rise of the LED drive power supply and prolong the service life of the drive power supply;

6. Whether the lamps have excellent explosion-proof and anti-static ability, and whether they can work safely in various places with inflammable, explosive and strong corrosive gases.
