Process flow

The air compressor compresses the raw air into high-pressure air, sends it to the air buffer tank to stabilize the pressure, and then further removes moisture, oil mist, etc. through the filter, and freezes and dehydrates through the refrigerated dryer to remove a large amount of moisture, and then enters the third stage. The filter further filters harmful substances, and then the clean compressed air enters from the bottom of the adsorption tower. After the air flow is diffused through the air diffusion device (universal spiral or porcelain ball), it evenly enters the adsorption tower for oxygen and nitrogen adsorption and separation, and then exits from the outlet end. The nitrogen flows out and enters the nitrogen storage tank. This nitrogen production process takes about 1 minute. Afterwards, through pressure equalization and pressure reduction (to normal pressure), the adsorbed impurity components (mainly oxygen) are removed, and the regeneration of the adsorbent is completed. The two adsorption towers operate in alternating cycles, continuously feeding raw air, and continuously producing qualified nitrogen.

Application

Inert Gas Protection Lithium battery production involves several stages where materials and reactions are sensitive to oxygen. These processes require an inert atmosphere to prevent oxidation and other detrimental reactions that could compromise the battery's performance and safety. Nitrogen generators are capable of supplying high-purity nitrogen, creating the necessary inert environment to protect these sensitive materials and reactions.

Atmosphere Control Precision in controlling the atmospheric composition within the reaction environment is crucial for certain steps in lithium battery manufacturing. This control ensures the stability of the reactions taking place and the quality of the final product. A nitrogen generator is an essential tool in achieving this, as it can provide a regulated nitrogen atmosphere tailored to the specific needs of each production step.

Cleaning and Drying In the lithium battery manufacturing process, various components and materials require thorough cleaning and drying to ensure they are free from contaminants that could affect performance or induce failure. Nitrogen generators provide dry nitrogen, which is instrumental in these cleaning and drying stages, ensuring that components are pristine and moisture-free before assembly.

Conclusion Nitrogen generators play a pivotal role in the lithium battery production industry. By providing high-purity nitrogen, they offer inert gas protection, atmosphere control, and support in cleaning and drying processes. These functions are critical in ensuring the stability and quality of the production process, ultimately leading to higher quality and more reliable lithium batteries.
