Explosion proof high bay led light in the chemical plant lighting in the fundamental role and application practice

Introduction: chemical plant lighting special needs and the importance of Explosion proof high bay led light

Chemical plants as a typical high-risk industrial environment, the presence of flammable and explosive gases, dust and corrosive substances, the safety, reliability and durability of the lighting equipment to put forward stringent requirements.

Traditional ordinary lamps and lanterns are difficult to meet the needs of such scenes, and Explosion proof high bay led light with its explosion-proof performance, high energy efficiency and intelligent adaptability, into a chemical plant to protect the safe production of core equipment.

First. Explosion proof high bay led light core technology advantages

1. Explosion-proof performance and safety design

Explosion proof high bay led light using explosion-proof [Exd] or increased safety [Exe] structural design, approved to strengthen the shell material [such as stainless steel], sealing process [IP66 and above protection level] and internal electrical isolation technology, effectively preventing sparks or high-temperature surfaces ignited by explosive environments.

For example, for IIA, IIB, IIC explosive gas explosion-proof lamps and lanterns, the surface temperature can be controlled in the T1-T6 group within the range [such as T4 group maximum temperature ≤ 135 ℃], significantly reducing the potential safety hazards.

2. Energy efficient and long life

LED light source Explosion proof high bay led lamp, energy consumption than traditional lamps and lanterns to reduce 40% -60%, life expectancy of up to 50,000 hours or more.

For example, a chemical plant to replace the LED explosion-proof lights, annual energy savings of more than 800,000 degrees, carbon emissions by about 260 tons, while significantly reducing the frequency of maintenance.

3. Environmental adaptability

Explosion-proof lamps with corrosion-resistant, waterproof and dustproof [IP66], shock-resistant and other characteristics, can be adapted to the chemical plant humid, dusty and chemically corrosive environment.

For example, stainless steel fasteners, casting process drive power to ensure stable operation in explosive dust environment [21, 22].

Second, Explosion proof high bay led light in the chemical plant typical application scenarios

1. Flammable and explosive area lighting

Tanks and reaction workshop: need to use explosion-proof grade Exd Ⅱ BT4 and above lamps and lanterns, to prevent volatile gases [such as benzene, ethylene] due to spark triggered by the explosion.

Pump room and compressor plant: closed space should be combined with standby lighting system [such as EPS power supply], to ensure that sudden power outages can still maintain 20% of the normal illumination, to help emergency operations.

2. Corrosive environment lighting

Acid and alkali storage area and wastewater treatment station: lamps and lanterns need to be approved WF2 anticorrosion certification, to resist chemical gas erosion, to extend the service life.

3. Emergency evacuation lighting

According to the “Fire Emergency Lighting, Evacuation Indicator System Technical Guidelines” [GB51309-2018], the Explosion proof high bay led lamp need to be integrated with the Class A emergency function, supplying ≥10% of the normal illumination in the event of a fire or power outage, and continue to be illuminated for more than 30 minutes, to ensure that the personnel can be safely evacuated.

Third, the chemical plant Explosion proof high bay led light selection and installation guidelines

1. Selection points

Qualification: Priority to the approval of ISO9001 certification and explosion-proof certificate [such as NEPSI certification] manufacturers.

Technical parameters: according to the explosive environment zoning [Zone 1 / Zone 2], gas type [IIA – IIC] and temperature group [T1 – T6] selection of lamps, for example, chemical pump room recommended Exd Ⅱ CT6 level.

Intelligent function expansion: With PLC or IOT control lamps and lanterns can implement brightness adjustment, fault alarm and other functions to improve management efficiency.

2. Improvement of installation method

Multi-scenario adaptation: supply ceiling-mounted, wall-mounted, boom-mounted and other installation options to adapt to the complex structure of chemical plants. For example, the tank area can be installed using guardrail type to avoid obstacles.

Fourth. Intelligent momentum: Explosion proof high bay led light and intelligent factory integration

1. Intelligent control system

Approved integrated light sensor, temperature and humidity sensors and PLC controllers, Explosion proof high bay led lamp can automatically adjust the brightness, color temperature. For example, refining and chemical plant area lamps and lanterns can be based on natural light intensity dynamic replenishment, saving more than 30% of energy consumption.

2. Remote operation and maintenance and safety monitoring

With the help of IoT platform, real-time monitoring of lamp status, fault warning and remote maintenance are implemented. A chemical plant approved the deployment of intelligent systems, annual maintenance costs reduced by 50%, the efficiency of accident response increased by 70%.

Fifth, application cases: Explosion proof high bay led light in the chemical plant practice results

Case 1: a petrochemical company tank area lighting renovation

Measures: Replace 200 sets of traditional metal halide lamps with LED Explosion proof high bay led lamp [ExdⅡBT4, IP66], and install intelligent control system.

Effect: annual power savings of 830,000 kWh, reducing carbon emissions by 266 tons; accident rate decreased by 40%, maintenance costs reduced by 60%.

Case 2: fine chemical workshop emergency lighting upgrade

Measures: Deploying explosion-proof Class A emergency lamps and lanterns, linking with the fire alarm system, and automatically lighting up after the main power supply is cut off.

Effect: 100% of the evacuation path illumination rate, one-time approval for fire acceptance.

Sixth, the future outlook: technological innovation and deepening of industry standards

Accompanied by the development of materials science and intelligent technology, Explosion proof high bay led lamp will be higher protection level [such as IP68], lower energy consumption [luminous efficacy > 200lm / W] and modular design evolution.

At the same time, the industry needs to further refine the chemical industry lighting guidelines [such as API RP 540], to promote explosion-proof lamps and lanterns and Industry 4.0 deep integration.

Conclusion

Explosion proof high bay led light are not only the cornerstone of chemical plant lighting safety, but also the implementation of green production and intelligent transformation of the fundamental equipment. Selection of highly adaptable, highly reliable products, combined with scientific operation and maintenance strategies, for chemical companies to continue to create safety and economic benefits.
