New Regenerative Incinerator RTO in Waste Gas Treatment of Lithium Battery Coating Production Line

The lithium battery coating process is a key step in the manufacturing process of lithium-ion batteries, which involves the uniform application of active materials to the current collector (usually copper or aluminum foil). This process is essential to ensure the performance, consistency and reliability of the battery.

In the production process of lithium batteries, especially in the coating production line stage, a variety of volatile organic compounds (VOCs) will be produced, which will affect product quality, and even endanger the health of employees and pollute the atmospheric environment. The VOCs in the coating production line mainly come from the following aspects:

Solvent:In the preparation of the electrode slurry, an organic solvent such as NMP (N-methylpyrrolidone) is used to adjust the viscosity and fluidity of the slurry. These solvents volatilize during the coating and drying process, resulting in the generation of VOCs.
Adhesives and Additives:Certain binders and additives may contain organic compounds, which may also volatilize during processing and heating.
Membrane material:Organic compounds may also be volatilized if the membrane material needs to be heated or otherwise treated during processing.

The generation of these VOCs is mainly related to material properties and processing conditions (such as temperature, air flow, etc.).

MegaunityWith many years of research and development experience, a comprehensive VOCs treatment scheme is designed from the perspective of efficiency, safety, stability and economy for different exhaust gas composition, air volume and concentration. The system adopts a variety of process combination design to ensure targeted treatment of various organic waste gas components.

Key technical features

Pretreatment RTO Regenerative Oxidation Furnace：Through a series of pre-treatment measures, such as filtration, adsorption and cooling, the safety of exhaust gas into the RTO equipment is ensured, and the overall treatment efficiency is improved.
Multi-energy heating options:The RTO regenerative oxidation furnace can choose different heating energy sources according to the actual situation, including electric energy, combustible gas or organic solvent, etc., to meet the needs of different application scenarios.

Program Advantages

Efficient governance:According to the specific composition of the exhaust gas, the most suitable pretreatment and post-treatment process is adopted to ensure the high efficiency of VOCs removal rate.
Security:Multiple safety protection measures, including reliable valve control system, perfect HAZOP analysis and emergency plan in case of emergency, ensure the long-term stable operation of the system.
Energy-saving economy:The optimized exhaust gas collection system reduces transport resistance and reduces energy consumption; under appropriate conditions, RTO can achieve self-sustaining operation, further reducing operating costs.
Flexible configuration:The modular structure design allows flexible layout according to site conditions, maximizing the use of space and reducing the footprint.

Through this advanced VOCs governance system, Megaunity not only help companies meet strict environmental emission standards, but also provide companies with more economical and efficient solutions to promote sustainable development.

Case Introduction of VOCs Governance in Megaunity Lithium Battery Enterprises

Project Background

A lithium battery manufacturer is facing the problem of organic waste gas emission, which mainly comes from the volatilization of organic solvents such as N-methyl pyrrolidone (NMP), ethyl methyl carbonate (EMC) and dimethyl carbonate (DEC). In addition, the exhaust gas also contains oil mist and fluorinated inorganic substances. The enterprise's system is designed to have a total air volume of 15,000 cubic meters per hour.

Megaunity Solution Overview

According to the specific needs of customers and exhaust gas characteristics, Megaunity carefully designed a comprehensive VOCs treatment program. This scheme uses an electric heating regenerative thermal oxidizer (RTO) as the core processing equipment, and combines efficient pre-treatment and post-treatment processes to ensure the high efficiency, safety and energy saving of the whole system.

Program highlights:

Optimized exhaust gas collection system: Through careful design, the resistance in the exhaust gas collection process is reduced, and the operating cost is effectively reduced.
High stability and flexibility: choose high quality valve components, provide a variety of operating modes to adapt to different working conditions.
Compact and modular design: Modular structure makes full use of limited space and significantly reduces floor space.
Self-sustaining operation capability: Under the appropriate exhaust gas concentration conditions, the system can achieve self-sustaining operation without additional energy input, significantly reducing operating costs.
Comprehensive security: Multi-level security measures were implemented and HAZOP (Hazard and Operability Study) analysis was completed to ensure the long-term stable and safe operation of the system.

Case results

After Megaunity professional team construction commissioning, the project has been successfully put into operation. The treated exhaust emissions are in full compliance with relevant national standards, including but not limited to the Integrated Emission Standard for Air Pollutants (GB16297-1996), the Emission Standard for Battery Industry Pollutants (GB30484-2013) and the Emission Standard for Odor Pollutants (GB1454-93/draft for comments).

Through this advanced VOCs treatment system, the environmental performance of the lithium battery manufacturer has been significantly improved, not only to meet strict emission regulations, but also to lay a solid foundation for its sustainable development.
