Explosion proof exit light in the refinery applications

First, the refinery environment on the Explosion proof exit light rigid demand

Refinery as the core scene of the petrochemical industry, there are a large number of flammable and explosive gases [such as methane, propane], dust, accompanied by high temperature, humidity, corrosive environment and other characteristics.

Ordinary lighting equipment can not meet the safety requirements of such high-risk places, and Explosion proof exit light with its special design and performance, into the protection of personnel evacuation, production safety core equipment.

1.1 Explosive environment suitability: refineries often belong to the explosive gas environment Zone 1, Zone 2 and combustible dust environment Zone 20-22, Explosion proof exit light need to comply with Exd IIB/IIC T6 and other high-level Explosion proof certification to ensure that the extreme conditions do not cause sparks or high-temperature ignition risk.

1.2 Emergency lighting function: In case of sudden power failure or accident, the Explosion proof exit light with built-in nickel-metal hydride batteries or lithium batteries can be automatically switched to the emergency mode, supplying up to 90-180 minutes of continuous lighting and guiding the personnel to evacuate at high speed.

1.3 Tolerance of harsh environments: the shell is made of aluminum alloy die-casting + high-pressure electrostatic plastic spraying process, with a protection level of IP65, corrosion-resistant, dust-proof and waterproof, and adapts to the temperature range of -20 ℃ to +50 ℃ and 95% humidity environment.

Second, Explosion proof Exit lys Core Technical Advantages

1. High safety design

Explosion proof structure: the lamp adopts Explosion proof shell and thread sealing technology, which effectively isolates the internal circuit from the external explosive gas and conforms to Exd IIB/IIC T6 Explosion proof standard, applicable to IIA/IIB/IIC gas environment in oil refineries.

Low power consumption and long life: adopting high brightness LED light source, the power is as low as 2W-5W, and the life time can reach 100,000 hours, which reduces the maintenance frequency and cost.

2. Intelligent emergency function

Automatic switching and charging: automatic charging during normal power supply, switching to emergency mode within 0.3 seconds after power failure, ensuring that the evacuation sign is continuously visible. Multi-mode installation: support ceiling, wall mounting and other installation methods, adapting to the complex spatial structure of the refinery.

3. Ergonomics improvement

Wide-angle lighting design: the irradiation angle reaches 220 degrees, the light is uniform and glare-free, avoiding visual fatigue and improving evacuation efficiency.3. Customized signage: the user can choose electronic light-emitting boards or piezoelectric effect markers to meet the needs of different scenarios.

Third, the refinery in the Explosion proof exit lys selection and configuration proposition

1. Selection of the basic parameters

Explosion proof grade: Exd IIB/IIC T6 is preferred, covering most of the explosive gas environment in the refinery.

Emergency duration: according to the size of the plant to choose 90 minutes or 180 minutes emergency model, to ensure sufficient evacuation time.

Protection performance: IP65 protection grade and WF1/WF2 anti-corrosion grade are the basic requirements to cope with the highly corrosive environment in the refinery.

2. Configuration strategy

High-density area coverage: Bidirectional signs are set up every 15 meters in the core areas of oil storage tanks, reaction devices and other explosion risk areas.

Multi-scene adaptation: wall-mounted in narrow channels, ceiling-mounted in open areas, combined with yellow or green high-contrast light source to enhance recognition.

Fourth, application cases: Explosion proof exit light actual performance verification

After upgrading the lighting system of a large oil refinery, the following results were achieved by using Explosion proof exit light:

Accident response efficiency: 2024 a sudden power outage, the emergency lighting system automatically started within 180 minutes to guide the safe evacuation of more than 300 employees.

Operation and maintenance cost reduction: LED light source and maintenance-free design makes the annual maintenance cost reduced by 40%, equipment failure rate decreased by 70%.

Compliance guarantee: approval of ISO9001 quality management system certification, in line with national guidelines for Explosion proof appliances, to avoid the risk of penalties due to equipment non-compliance.

Fifth, the future momentum: intelligent Explosion proof exit lys innovation direction

Internet of things integration: approved sensors real-time monitoring of the state of the lamps and lanterns, remote warning of battery failure or light source abnormalities, to enhance management effectiveness.

Green energy-saving upgrades: combined with solar power supply system to further reduce energy consumption, adapting to the refinery’s sustainable development intentions.

Dynamic guidance function: Develop programmable LED panels to intelligently adjust evacuation path instructions according to the location of the fire source, maximizing the escape success rate.

Konklusion

Explosion proof exit light is an indispensable part of the refinery safety system. Its high Explosion proof performance, long-lasting emergency response capability and intelligent design not only safeguard the lives of personnel, but also provide technical support for the enterprise to reduce costs and increase efficiency.

Along with the upgrading of industry standards and technology iteration, the future Explosion proof exit light will be more deeply integrated into the Industry 4.0 framework, becoming the core safety node of the intelligent refinery.
