Explosion proof solar led: metallurgical industry safety lighting green technology innovation

First, the metallurgical industry lighting special challenges and Explosion proof solar led suitability

Metallurgical industry production environment with high temperature, strong vibration, dust intensive, flammable gas mixture [such as hydrogen, carbon monoxide] and other complex characteristics, the traditional grid-powered lamps and lanterns are easy to spark or high temperature triggered by the risk of explosion, and high energy consumption, maintenance difficulties.

Explosion proof solar led approved the integration of explosion-proof technology and solar off-grid power supply system, into the steel mill, coking plant, raw materials yard and other high-risk areas of the ideal lighting programme.

Let’s say, a steel enterprise after the introduction of Explosion proof solar led, annual power cost reduction of 45%, maintenance frequency reduced by 60%.

Second, Explosion proof solar led in the metallurgical industry core advantages

1. Intrinsically safe and explosion-proof certified Explosion proof solar led using explosion-proof shell [Ex d IIC T6 Gb guidelines] and safety-enhancing circuit design, the surface temperature is strictly controlled in the T6 group [≤ 85 ° C], to prevent the ignition of explosive gases Ⅱ C [such as hydrogen].

Its IP66 protection level can withstand high dust and metal particles in metallurgical plants, ensuring long-term stable operation.

2. Off-grid power supply and energy-independent solar integration: Equipped with high-efficiency monocrystalline silicon panels [conversion efficiency ≥ 22%], with energy-storage colloidal batteries [life expectancy of 5-10 years], a single-day range of 3 consecutive days of cloudy and rainy illumination, suitable for raw material stockpiles without grid coverage or remote work areas.

3. Energy-saving benefits: 150W Explosion proof solar led, for example, compared with the traditional 400W high-pressure sodium lamps, annual power savings of more than 2,500 kWh, reducing carbon emissions of about 1.2 tonnes.

4. Extreme environmental adaptability to high temperatures and vibration: Aluminium alloy shell combined with copper-aluminium composite heat dissipation structure, to help -40 ℃ to +60 ℃ wide temperature range of operation, resistance to high temperature radiation and equipment vibration of the steelmaking workshop.

5. Anti-corrosion design: Epoxy resin spraying process approved 1,000 hours of salt spray test, resisting metallurgical acid mist and metal dust corrosion.

6. Intelligent control and low-maintenance integrated IoT module to help remote brightness adjustment, fault warning and battery health monitoring.

For example, a coking plant approved the intelligent system to implement night operation illumination adaptive adjustment, energy saving rate increased by 30%.

Third, the metallurgical industry typical scenes and Explosion proof solar led get the job done programme

1. Steelmaking workshop and high-temperature areas

High-temperature resistance: 80 ℃ LED light source module, light efficiency ≥ 140 lm / W, covering a radius of 25 metres, to avoid steel splash triggered equipment damage.

Emergency function: switch the backup power supply within 0.5 seconds after power failure, continuous lighting ≥ 4 hours, to ensure safe evacuation in case of sudden power failure.

2. Raw material dumps and open pit mines

Off-grid power supply: solar energy system is adapted to the area without power grid, reducing the cost of cable laying and increasing the coverage area of a single light by 40%.

Dust protection: sealed lens design prevents dust intrusion, light decay rate ≤ 3%/year, extending the service life.

3. Coking plant and gas purification area

Enhanced explosion-proof grade: Ex dⅡC T6 certification, adapting to hydrogen and coke oven gas environment, reducing the risk of combustion and explosion.

Improvement of corrosion resistance: nano-coated reflective panels increase the light transmission rate by 15%, resisting the corrosion of hydrogen sulphide and ammonia.

Modification case: a large metallurgical group deployed 200 sets of Explosion proof solar led in the raw material yard, saving 780,000 yuan in annual electricity costs and reducing the equipment failure rate by 70%.

Fourth, selection and installation specifications

1. Selection points explosion-proof level matching: according to the type of gas [Ⅱ C] choose Ex d Ⅱ C T6 guidelines, dust environment needs to be additional Ex tD A21 certification.

2. Battery capacity calculation: Take 4 hours of average daily light as an example, 150W lamps need to be equipped with 180Ah batteries and 300W solar panels to ensure that the duration of redundancy.

3. Improved installation and maintenance angle: The tilt angle of the solar panel is adjusted according to the local latitude +15°, which enhances the efficiency of capturing light energy.

4. Regular maintenance: quarterly cleaning of the panel surface dust, detection of battery capacity degradation [≤15%/year].

Fifth. Future Momentum: Intelligent and Optical Storage Integration

AI and 5G integration: approval of environmental sensors to monitor gas concentration in real time, linkage lighting system automatic alarm and start ventilation.

Optical storage system upgrade: lithium storage instead of gel batteries, cycle life increased to 8,000 times, suitable for zero-carbon metallurgical intentions.

Modularised design: High-speed replacement of light source and battery module, maintenance efficiency increased by 50%.
