Explosion proof solar lights: steel plant safety lighting off-grid solutions and energy efficiency breakthroughs
First, the core challenges of steel plant lighting and Explosion proof solar lamp suitability
Steel mill environment with high temperature, high dust, strong vibration, flammable gases [such as hydrogen, carbon monoxide] and complex terrain [such as raw material yards, steelworks, coking plant] and other characteristics of the traditional grid-powered lamps and lanterns there is the risk of sparks, high wiring costs, maintenance difficulties and other challenges.
Explosion proof solar lights approved the integration of Explosion proof technology [Ex dⅡC T6 certification] and solar off-grid power supply system, into the steel mill high-risk areas of the ideal lighting options.
Let’s say, a steel enterprise transformation, annual maintenance costs reduced by 50%, carbon emissions by 35%.
Second, Explosion proof solar lights in the steel plant core advantages
1. Intrinsically safe and Explosion proof certification Explosion proof solar lamps using Explosion proof shell design, surface temperature is strictly controlled in the T6 group [≤ 85 ° C], to isolate the internal arc and sparks, suitable for Ⅱ C explosive gas environment [such as hydrogen gathering area of steelmaking workshop].
Its IP66/IP67 protection level can withstand high dust, metal splash and rainwater washout in steel mills, prolonging the life of the equipment.
2. Off-grid power supply and zero-carbon solar system: Equipped with monocrystalline silicon panels (conversion efficiency ≥ 22%) and lithium batteries (cycle life ≥ 5,000 times), the single-day range can help with continuous rain and shine for 3 days, which is suitable for raw material yards without grid coverage or remote operation areas.
3. Energy-saving benefits: 150W Explosion proof solar lamp, for example, compared with the traditional 400W high-pressure sodium lamp, annual power savings of more than 2,500 kWh, reducing carbon emissions by about 1.2 tonnes.
4. Extreme environmental adaptability to withstand high temperatures and vibration: Aluminium alloy shell combined with copper-aluminium composite heat dissipation structure, to help -40 ℃ to +80 ℃ wide temperature range of operation, resistance to high temperature radiation in the steel workshop and vibration of lifting equipment.
5. Anti-corrosion design: Epoxy resin spraying process is approved for 1,000 hours of salt spray test, resisting acid mist and metal dust corrosion in steel mills.
6. Intelligent control and low-maintenance integrated IoT module to help remote dimming [such as night work brightness automatically reduced by 30%], fault warning and battery health monitoring, reducing the frequency of manual inspection.
Third. Typical scenes in steel mills and Explosion proof solar lights to handle the programme
1. Steelmaking workshop and high-temperature operation area
High-temperature resistance: configure temperature 80 ℃ LED light source module, light efficiency ≥ 140 lm / W, covering a radius of 25 metres, to avoid steel splash damage to the lamps.
Emergency lighting: switch the backup power within 0.5 seconds after power failure, continuous lighting ≥ 4 hours, in line with UL 924 guidelines.
2. Raw material dumps and open pit mines
Off-grid deployment: solar system eliminates cable laying, increasing the coverage area of a single light by 40%, reducing wiring costs and construction risks.
Dust protection: Sealed lens design prevents dust intrusion, light decay rate ≤3%/year, suitable for coal dust and iron ore dust environment.
3. Coking plant and gas purification area
Explosion proof enhancement: Ex dⅡC T6 certification for hydrogen and coke oven gas environments, built-in gas sensor linkage alarm system to reduce the risk of combustion and explosion.
Improved corrosion resistance: Nano-coated reflectors increase light transmission by 15% and resist corrosion by hydrogen sulphide and ammonia.
Modification case: a steel plant in the coking area after the deployment of 200 sets of Explosion proof solar lamps, the annual electricity bill savings of 780,000 yuan, equipment failure rate reduced by 70%.
Fourth, selection and installation specifications
Selection points Explosion proof level matching: according to the type of gas [Ⅱ C class] choose Ex d Ⅱ C T6 guidelines, dust environment additional Ex tD A21 certification.
Battery capacity calculation: average daily light 4 hours, for example, 150W lamps and lanterns need to configure 180Ah lithium batteries and 300W solar panels to ensure that the duration of redundancy.
Improved Installation and Maintenance Angle: The tilt angle of the solar panels is adjusted according to the local latitude +15° to enhance the efficiency of light energy capture.
Regular maintenance: quarterly cleaning of the panel surface dust, detection of battery capacity degradation [claim ≤ 15% / year].
Fifth. Future Momentum: Intelligent and Optical Storage Integration
AI and 5G integration: Approve environmental sensors to monitor gas concentration in real time, linkage lighting system to automatically alarm and start ventilation.
Optical storage system upgrade: lithium energy storage cycle life is increased to 8,000 times, suitable for steel mills with zero carbon intention.
Modular design: High-speed replacement of light source and battery module, reducing maintenance time by 50%.
FAQ: Explosion proof solar lights common problems
Q1: How to choose the Explosion proof solar lamp Explosion proof grade for steel mills?
A: According to the type of ambient gas [such as Ⅱ C hydrogen] to choose Ex d Ⅱ C T6 guidelines, dust areas need to be attached to the Ex tD A21 certification, advocating the implementation of the hazardous area classification by professional organisations.
Q2: Can the lighting be sustained under rainy weather?
A: Yes. Configuration of 180Ah lithium battery 150W lamps can maintain 6 hours of lighting per day under 3 consecutive days of cloudy and rainy environment.
Q3: Does the intelligent control system increase the cost?
A: The initial investment increases about 10%-15%, but approved energy saving and reduce the frequency of manual inspection, 1.5-2 years to recover the additional cost.
