Lithium battery production line waste gas waste heat recovery solution

As an emerging clean energy industry, the lithium battery industry's waste gas treatment and waste heat recovery are crucial to environmental protection and resource utilization. During the lithium battery production process, some waste gas and waste heat may be generated. The following are common treatment and recovery solutions for these two aspects:
Exhaust gas treatment solution:
1. Exhaust gas collection system: Establish an exhaust gas collection system to collect the generated exhaust gas in a centralized manner. This can prevent the exhaust gas from being emitted into the environment and reduce environmental pollution.
2. High-efficiency purification device: Use high-efficiency purification devices, such as activated carbon adsorption, wet desulfurization, denitrification and other technologies to treat the collected exhaust gas and remove harmful components and pollutants to meet emission standards.
3. Recycling: Some recyclable waste gas components can be recycled. For example, some organic solvent waste gas can be recycled and reused to reduce the loss of raw materials.
Waste heat recovery solution:
1. Heat recovery heat exchanger: During the production of lithium batteries, a certain amount of waste heat may be generated. Through heat recovery heat exchanger technology, the waste heat can be recovered and used to heat other equipment that requires thermal energy or heat water supply, thus realizing energy reuse.
2. ORC system: Organic Rankine Cycle system can use low-temperature waste heat and convert it into useful electrical energy. This system is suitable for processing low-temperature waste heat, such as the heat generated during the production of lithium batteries.
3. Evaporation and concentration: In the process of lithium battery manufacturing, aqueous solutions are produced in some processes. The waste heat can be recovered through the evaporation and concentration process to evaporate the water to obtain a more concentrated solution and recover heat energy at the same time.
The above solutions are just some common methods of waste gas treatment and waste heat recovery. In actual application, specific planning and implementation are required according to the production process and waste gas and waste heat characteristics of different enterprises, combined with environmental protection laws and technical requirements. The comprehensive use of multiple technical means will help the lithium battery industry achieve a cleaner and more efficient production process and reduce the impact on the environment.
