In the current era of profound changes in the energy landscape,Energy storage equipment serves as a key hub for energy storage and allocation,Its importance is increasingly prominent。Whether it is a large-scale grid level energy storage power station,Still a distributed home energy storage system,The stable operation of energy storage equipment is crucial for ensuring energy supply、Improving energy efficiency is crucial。however,Energy storage equipment during long-term operation,Will be affected by dust、Oil pollution、Invasion of various types of dirt such as corrosive substances,These dirt not only affect the performance and lifespan of the equipment,It may also cause safety hazards。Dry ice cleaning machine with its unique advantages,Plays a critical role in cleaning energy storage equipment。

Dirt hazards and cleaning difficulties of energy storage equipment

The multiple hazards of dirt on energy storage devices

• Reduce heat dissipation efficiency:Energy storage devices generate a large amount of heat during the charging and discharging process,A good cooling system is needed to maintain normal operating temperature。Dirt will adhere to the heat sink、On cooling components such as fans,Obstructing air circulation,Reduce heat dissipation efficiency。for example,If thick dust accumulates on the heat sink of the battery energy storage system,Will cause an increase in battery temperature,Accelerate battery aging,Shorten battery life,It may even cause thermal runaway of the battery,Causing safety accidents。
• Affects electrical performance:Conductive substances in dirt may form conductive pathways at the electrical connection points of energy storage devices,Causing a short circuit、Leakage and other issues。meanwhile,Dirt may also affect the insulation performance of electrical components,Increase the risk of electrical failures in equipment。In supercapacitor energy storage devices,Dirt may cause a decrease in insulation performance between electrodes,Affects the charging and discharging performance and stability of capacitors。
• Accelerate equipment corrosion:Some dirt contains corrosive substances,Like acidic gases、Salt content, etc,These substances will undergo chemical reactions with the metal components of energy storage devices,Causing equipment corrosion。Corrosion can cause a decrease in the mechanical strength of equipment,Affects the sealing and reliability of equipment,Increase the cost of equipment maintenance and replacement。

Limitations of traditional cleaning methods

• Manual wiping:Low efficiency and poor effectiveness:Manual wiping requires a significant amount of manpower and time investment,For some large energy storage devices,Like an energy storage container,Extremely difficult to clean。Cleaning personnel need to use brushes、Cleaning cloth and other tools,Effortlessly wiping away dirt from the surface of the equipment,Not only is the labor intensity high,And it is difficult to completely remove dirt from gaps and corners。in addition,Manual wiping can easily leave scratches on the surface of the equipment,Affects the appearance and accuracy of the equipment。
• Wash and clean with water:There are safety hazards present:Although washing and cleaning can remove some dirt,But for energy storage devices,Washing with water may cause a short circuit in the equipment、Damage to electronic components and other issues。Energy storage devices typically have a large number of electrical circuits and electronic control systems inside,Once in contact with water,May cause serious safety accidents。not only ... but,After washing with water, the equipment takes a long time to dry,Easy to breed dirt again in humid environments。
• chemical cleaning:Environmental protection and compatibility issues:Chemical cleaning uses chemical agents to dissolve dirt,But chemical agents are usually corrosive and irritating,May cause damage to the materials of energy storage devices,Affects the performance and lifespan of equipment。meanwhile,The waste liquid after chemical cleaning contains a large amount of harmful substances,Improper handling can cause serious pollution to the environment。in addition,Energy storage devices made of different materials have varying compatibility with chemical agents,Choosing the appropriate chemical agents also poses certain difficulties。

Working principle and core advantages of dry ice cleaning machine

Deep analysis of working principle

Dry ice cleaning machineUtilizing extremely low temperature dry ice pellets,Driven by compressed air,Spray at high speed onto the dirt on the surface of the energy storage device。When dry ice particles collide with dirt,Due to the low-temperature characteristics of dry ice,Dirt will quickly become brittle。meanwhile,Dry ice sublimates into carbon dioxide gas at the moment of impact,Rapid expansion of volume,Generate strong impact force,Peel the brittle dirt off the surface of the equipment。The entire cleaning process does not require the use of water or chemicals,It is a dry type、Non destructive cleaning method。
