Explosion-proof Inspection Robot Successfully Alerts to Hydrogen Sulfide Leak

Hazardous chemicals, due to their flammable, explosive, toxic, harmful, and highly corrosive properties, are ubiquitous throughout the production, operation, storage, and usage phases of chemical manufacturing. Improper management or handling can readily trigger major safety incidents, causing irreversible damage to human life, facilities, equipment, and the ecological environment. According to public reports, a wastewater treatment station at a battery company's industrial park once experienced a major poisoning incident due to hydrogen sulfide (H₂S) accumulation in the hydrolysis acidification tank. The incident resulted in three deaths, one injury, and direct economic losses exceeding 320 million yuan.

Against this backdrop, intelligent and unmanned inspection technologies are emerging as critical tools for risk prevention and control in the hazardous chemicals sector. A publicly listed pump manufacturer partnered with Xspirebot to successfully integrate an explosion-proof inspection robot chassis into its proprietary intelligent recognition system. This system was deployed at a gas gathering station operated by a petroleum enterprise in Yulin. During routine inspections, the system accurately detected a trace hydrogen sulfide leak at the pipe connection of Reactor No. 3. The timely warning successfully prevented poisoning risks for four inspection personnel.

This project has not only significantly enhanced the inherent safety level on-site but also redefined traditional safety management models:

By implementing an “8-hour manned monitoring + 4-hour comprehensive patrol” mechanism, it achieves round-the-clock dynamic surveillance of high-risk areas;

It breaks away from outdated processes reliant on manual coordination for inspections, driving the transformation of safety oversight toward “proactive prevention”;

It effectively reduces operational intensity and exposure risks for frontline personnel, lowering the annual accident rate from 5% to a remarkable 0.2%.

This case study fully demonstrates that explosion-proof inspection robot chassis (equipped with intelligent recognition systems) have become a crucial pillar for the hazardous chemicals industry to achieve precise risk management and enhance safety production efficiency.

Explosion-proof inspection robots have extensive applications across numerous hazardous environments and industries. The following are the primary industrial application areas:

In the oil and gas industry, across exploration, extraction, and processing operations, explosion-proof inspection robots can be deployed to patrol pipelines, storage tanks, drilling platforms, and chemical facilities, monitoring for leaks, fire hazards, and equipment conditions.

Safety inspections and monitoring at hazardous chemical production and storage sites within the chemical industry help reduce the risk of personnel exposure to harmful substances.

In metallurgical plants and steel mills, robots can be deployed to inspect equipment and facilities in high-temperature, high-pressure, and hazardous gas environments, ensuring workplace safety.

Equipment inspections in the power industry for power plants, substations, and cable ducts to detect faults in the power system and potential fire hazards.

Pharmaceutical industry: Hygiene and safety inspections for drug production and storage facilities to ensure compliance with stringent pharmaceutical manufacturing requirements.

Mining industry: Safety monitoring and inspections for underground and open-pit mines to help reduce risks of explosions and harmful gas exposure.

Equipment and material monitoring for aerospace factories and laboratories within the aerospace industry to ensure a highly clean and safe production environment.

In the food processing and manufacturing industries, this robotic chassis is used for sanitation and safety inspections in food processing plants to ensure food production meets safety and quality standards.

In the nuclear energy industry, it is employed for equipment monitoring and inspection at nuclear power plants and nuclear facilities to ensure radiation safety and environmental protection.
