The purpose of this invention is to propose an oxygen depressurization explosion-proof electrostatic vacuum noise silencing device, belonging to the field of safe handling of flammable and explosive industrial gases. The device includes a vertical cylindrical body, a bottom air inlet, a top exhaust outlet, supporting legs, and inside the cylinder, a bottom flame arrester, a multi-stage pressure reduction and deceleration assembly, an electrostatic elimination sound-absorbing layer, and a top flame arrester. Through multi-stage U-shaped microporous baffles, progressive pressure reduction and deceleration are achieved; the metal wire sound-absorbing layer eliminates static electricity and absorbs noise; and the upper and lower double-layer flame arresters block the backfire path, completely solving the problems of electrostatic explosion, backfire, and noise pollution during oxygen depressurization. This invention is suitable for high-risk scenarios such as liquid oxygen stations, ensuring the safe production of flammable and explosive chemical facilities, avoiding personal injury and property damage, while meeting environmental protection and noise reduction requirements.

The invention provides an unmanned aerial vehicle routing inspection method and system based on semantic guidance and an asset value cost graph, and the method comprises the steps: reasoning a possible distribution region of a target when the target is not directly observed through analyzing the structure law of semantic information, such as an equipment number, a function partition identifier and the like, in a transformer substation; generating a confidence map to guide the unmanned aerial vehicle to efficiently inspect; constructing a semantic cost graph fusing the static asset value and the dynamic operation risk, and quantifying potential loss of different regions when collision or falling occurs; according to the real-time health state of the unmanned aerial vehicle, semantic guidance is emphasized during normal inspection through a dual-guidance function fusion and switching mechanism, and the unmanned aerial vehicle is automatically switched to asset value cost minimization guidance in an abnormal or emergency state to realize safe disposal; the system adopts a framework of semantic reasoning, cost evaluation and flight control module decoupling, and guidance intelligence and control reliability are ensured. According to the invention, the inspection blindness of the unmanned aerial vehicle is obviously reduced, and the abnormality handling risk is reduced.

This invention discloses a method and system for removing hazardous gases from a special gas supply equipment, relating to the field of hazardous gas removal technology. The method includes: numerically simulating the gas flow path inside the equipment to identify hazardous gas retention areas; applying a magnetoacoustic coupling field to the retention areas to desorb the hazardous gases and migrating the desorbed gases to a preset safe treatment area; extracting and fusing optical and spectral features using a learnable encoder to obtain the physicochemical characteristics of the residual hazardous gases; constructing a digital twin model to simulate the residual diffusion behavior and retention risk of the residual hazardous gases within the equipment; optimizing the parameters of the magnetoacoustic coupling field and iteratively optimizing it until the hazardous gases are completely removed from the equipment. This invention improves the efficiency and directionality of hazardous gas removal, reduces the safety risks caused by residues, and thus ensures the stability of the special gas supply equipment operation and the safety of the operating environment.

This application provides an integrated control system and method for the safe storage and use of liquid ammonia. The system, by setting up an emergency unit for liquid ammonia storage, automatically lowers the liquid ammonia cylinder into a water tank using a lifting support frame upon detection of an ammonia leak. This achieves rapid and automatic submersion cooling and dilution absorption of the leak source at its source, significantly shortening emergency response time and substantially improving the system's inherent safety level and the efficiency of leak emergency handling. By incorporating a waste gas purification unit including an ammonia cracking tank, ammonia-containing tail gas is efficiently decomposed under high temperature and catalyst conditions, achieving thorough purification and safe treatment of the waste gas. Through a safety interlock control unit, multiple safety aspects, including explosion-proof isolation, leak detection, emergency response, pipeline shut-off, and waste gas purification, are organically integrated into a coordinated whole, achieving automated safety management throughout the entire process. This improves the reliability and efficiency of the overall emergency response and realizes integrated and coordinated control of the system.

This application discloses a method, apparatus, electronic device, medium, and product for determining the safe handling method for unmanned aerial vehicles (UAVs). The method includes: collecting multi-source perception data from the UAV; extracting features from the multi-source perception data to obtain an event feature vector; performing real-time calculation on the event feature vector to obtain a comprehensive risk value; using the comprehensive risk value to characterize the overall degree of danger currently faced by the UAV; determining the software risk level and hardware risk level based on the comprehensive risk value; and making a comprehensive decision based on the software risk level and hardware risk level to obtain a graded safe handling method. This method can solve the problem of poor flexibility caused by direct judgment in current UAV emergency handling.
