Anti explosion proof lamp in the fertilizer plant lighting in the fundamental application and safety innovation

Introduction: fertilizer plant lighting special needs and the core value of Anti explosion proof lamp

Fertilizer plant as a typical chemical production scenario, its production environment often exists ammonia, methane and other flammable and explosive gases, as well as fertilizer dust, high humidity, chemical corrosion and other risks.

Traditional lighting equipment in the high temperature, humidity or corrosive environment is prone to short-circuit, leakage or even explosion, threatening the safety of personnel and equipment. Anti explosion proof lamp with its explosion-proof structure, corrosion resistance and high stability, into the fertilizer plant safety lighting core solution.

In this paper, from the application scenarios, technical advantages, selection specifications and industry momentum and other dimensions, a comprehensive analysis of Anti explosion proof lamp in the fertilizer plant in the fundamental role of helping enterprises to implement safe production and cost reduction and efficiency.

First, the fertilizer plant explosion-proof lights core application scenarios

1 ammonia workshop and gas processing area

Ammonia process involves hydrogen, nitrogen and high temperature and pressure environment, leakage is easy to form explosive gas mixtures. Anti explosion proof lamp using Exd II CT6 explosion-proof certified design, approved to strengthen the shell and the internal circuit isolation, to ensure that the lamps and lanterns inside the spark will not ignite the external hazardous gases.

For example, 100W LED explosion-proof floodlight using high-strength aluminum alloy shell and tempered glass shield, impact strength of 7J, protection level of IP67, can withstand high-pressure gas impact and chemical vapor erosion.

2. Pelletizing workshop and dusty work area

Fertilizer granulation process generates dust [such as ammonium phosphate particles] to reach a certain concentration of explosive. Anti explosion proof lamp approved fully sealed structure and dust filter design [in line with IP65/IP66 guidelines], effectively blocking the dust into the lamp body.

For example, 30W explosion-proof ceiling light adopts double-layer silicone seals and stainless steel fasteners, and the surface is electrostatically sprayed, so it can be operated stably in the environment with dust concentration up to 200g/m³, and reduce the risk of dust explosion.

3. Raw material storage area and corrosive environment

Fertilizer raw materials [such as sulfuric acid, nitric acid] storage area there is a risk of corrosion of strong acid vapor. Anti explosion proof lamp using WF2 anti-corrosion coating [epoxy resin + fluorocarbon spray] and 316L stainless steel material, resistance to acid and alkali corrosion.

Wall-mounted 60W LED explosion-proof lights, for example, its shell salt spray test over 3000 hours, in the pH 2-12 corrosive environment life of up to 10 years or more, significantly reducing the frequency of equipment replacement.

Second, explosion-proof light technology advantages and performance breakthroughs

1. Explosion-proof safety and high reliability

Explosion-proof structure: explosion-proof cavity design approved stop engagement and threaded explosion-proof technology to ensure the effective release of explosive pressure, in line with IEC 60079-1 international standards.

Temperature control: the surface temperature of the lamps and lanterns is strictly controlled in the T4-T6 group [≤ 135 ℃], to avoid ignition of combustible gases.

2. Energy efficient and long life design

LED Anti explosion proof lamp luminous efficacy up to 120lm / W or more, compared with the traditional high-pressure sodium lamp energy saving 70%.

For example, a fertilizer plant will be upgraded to 50W LED explosion-proof lighting granulation workshop, the annual power consumption by 40%, the light source life of more than 60,000 hours, the light failure is less than 5%, reducing maintenance costs and downtime losses.

3. Improved environmental adaptability

Corrosion resistance: nano-ceramic coating and aluminum alloy anodic oxidation process, adapting to the acidic and alkaline environment of the fertilizer plant.

Intelligent heat dissipation: honeycomb heat dissipation structure with thermal conductive silicone grease, to ensure that the lamps and lanterns in the -40 ℃ to 60 ℃ range of stable work.

Fertilizer plant Anti explosion proof lamp selection and maintenance guidelines

1. Selection of basic parameters

Explosion-proof grade: Exd II CT6 grade is preferred, covering hydrogen [IIC class] and ammonia [IIA class] explosive environment.

Protection level: IP65 or above for dusty areas, IP67/WF2 for liquid corrosive areas.

Luminous flux adaptation: according to the area of the region to choose 30W-200W power, such as long and narrow channel selection of 40W, large synthetic workshop selection of 150W floodlights.

2. Installation and maintenance specifications

Installation method: wall-mounted, boom or flange mounted to avoid gas leakage points and mechanical collision areas.

Regular inspection: check the elasticity of the sealing ring and the corrosion of the surface of the lamp body every quarter, and replace the seals once every 2 years.

Safe operation: maintenance needs to cut off the power supply and wait for the lamps and lanterns to cool down, to avoid high temperature caused by scalding or gas explosion.

Fourth, the industry case: Anti explosion proof lamp practical application benefits

Case 1: a fertilizer plant synthesis workshop lighting transformation

The workshop used 80W LED explosion-proof floodlights to replace the traditional metal halide lamps, lighting uniformity increased by 50%, the annual failure rate from 12 times to 1 time, and successfully approved ISO 80079-36 explosion-proof safety certification.

Case 2: Southeast Asia fertilizer plant accident warning

In 2023, a fertilizer plant in Indonesia due to the use of non-explosion-proof lighting led to ammonia leakage explosion, resulting in three people seriously injured. This case highlights the need for explosion-proof lights in the chemical industry in high-risk environments.

Fifth. Future momentum: the integration of intelligent and green technology

1. Internet of Things integration: the approval of intelligent sensors to implement Anti explosion proof lamp remote brightness adjustment, fault warning and energy consumption monitoring to improve management efficiency. 2.

2. light environment improvement: adaptive optics technology can be dynamically adjusted according to operational requirements of the beam angle, reduce glare and improve energy efficiency.

3. Material innovation: carbon fiber composite materials and graphene heat dissipation technology applications, will further reduce the weight of the lamp and enhance corrosion resistance.

Conclusion: Anti explosion proof lamp – fertilizer plant production safety core security

Anti explosion proof lamp is not only the fertilizer plant compliance operation of rigid demand, but also to enhance production efficiency and reduce the overall cost of the fundamental equipment.

Enterprises need to be based on the production process, environmental risks and maintenance of the ability to choose the appropriate Anti explosion proof lamp models, and lay the scientific inspection and replacement mechanism.

In the future, with the popularization of intelligent technology and green materials, explosion-proof lights will continue to promote the fertilizer industry to a safer, more sustainable direction.
