Description

Technical Field

[0001] This invention relates to the field of high-pressure adaptable hyperbaric oxygen chamber air purification and filtration and intelligent operation and maintenance technology, specifically a high-pressure adaptable hyperbaric oxygen chamber air purification and filtration and intelligent operation and maintenance system. Background Technology

[0002] Hyperbaric oxygen chambers, as crucial medical and special environmental protection equipment, have extremely stringent requirements for air quality. They must not only maintain a stable oxygen concentration but also effectively remove harmful substances such as dust, gaseous pollutants, and microorganisms to prevent cross-infection and environmental degradation. Current air purification and filtration systems for hyperbaric oxygen chambers suffer from several shortcomings: First, their purification functions are limited, often consisting of simple particulate filtration, lacking the ability to deeply purify gaseous pollutants and microorganisms. Furthermore, the filter media is prone to saturation and frequent replacement, resulting in high maintenance costs. Second, the systems have poor adaptability, struggling to cope with pressure fluctuations under high-pressure environments, leading to leaks, decreased purification efficiency, and uneven flow distribution, resulting in air quality differences across different areas of the chamber. Third, their level of intelligence is low, lacking real-time and accurate monitoring of pollutant concentration, filter media status, and oxygen concentration. The purification strategy is fixed and cannot be dynamically adjusted according to actual operating conditions. Fourth, the safety assurance system is incomplete, lacking seamless switching between main and backup circuits and mechanisms for emergency leak handling, resulting in delayed fault response and potential safety hazards. Fifth, operation and maintenance are inconvenient, requiring on-site manual monitoring and maintenance, lacking remote monitoring, fault warnings, and firmware upgrades, leading to low operational efficiency.

[0003] Therefore, there is an urgent need for an air purification and filtration system with multi-stage deep purification, high-pressure adaptability, intelligent control, comprehensive safety assurance and remote operation and maintenance functions to solve the problems of incomplete purification, poor adaptability, insufficient intelligence, safety hazards and operation and maintenance difficulties of existing technologies, and to meet the stringent requirements of hyperbaric oxygen chambers.
