Efficient lithium battery production waste gas treatment method!

With the rapid growth of the new energy vehicle market, the demand for lithium batteries has also increased. However, inLithium battery production In the process, electrolyte and N-methylpyrrolidone (NMP) [expansion:NMP Recovery Technology The use of organic solvents such as] can produce volatile organic compounds (VOCs). The direct discharge of VOCs causes serious pollution to the environment. The development of efficient VOCs treatment technologies is essential for achieving sustainable development. Combined with the characteristics of VOCs waste gas in each section of the lithium battery production process, the Megaunity has launched a comprehensive and efficient comprehensive treatment plan to help customers meet strict environmental protection standards.

Characteristics and hazards of VOCs waste gas from lithium battery production

In the lithium battery manufacturing process, the electrolyte is one of the key components, which is usually composed of lithium salt, solvent and other additives. Due to its complex chemical structure, the electrolyte is easy to volatilize to form VOCs waste gas. In addition, NMP, as an important solvent in the coating process of the battery pole piece, also releases a large amount of VOCs in the drying process. If these harmful substances are directly discharged into the atmosphere without proper treatment, it will lead to the deterioration of air quality, aggravate the greenhouse effect, and pose a threat to the living environment of animals and plants.

Summary of VOCs treatment scheme for lithium battery production

In view of the above problems,Megaunity A set of comprehensive VOCs control scheme is proposed. The program is personalized according to the characteristics of VOCs generated in each production stage, through pretreatment filtration, acid gas special treatment and advanced.Regenerative Oxidation Furnace (RTO) A combination of various technical means, such as the effective removal of harmful substances in the exhaust gas, to meet the national emission standards.

pre-treatment filter

The pre-processing stage is the first line of defense for the entire system. The Megaunity is specially equipped with a high-efficiency filter device that can capture and separate dust particles, oil mist and other impurities in the exhaust gas to prevent them from causing damage to the equipment after entering the subsequent treatment unit. More importantly, this filter adopts an innovative online filter replacement design, which greatly simplifies the maintenance process, reduces downtime, and ensures the continuity and stability of production. At the same time, the fan part also adopts a one-use-one-standby strategy. When one fails, the other can immediately take over the work, realizing the real unattended automatic management.

Special treatment process

Considering that in some specific cases, such as the presence of strong corrosive acid gases such as hydrogen fluoride, the regular treatment method is difficult to work, the Megaunity has specially developed a targeted purification process for this purpose. This process can not only effectively convert hydrogen fluoride into harmless substances for discharge, but also protect other equipment from erosion and extend its service life.

RTO regenerative oxidation furnace

As the core processing equipment, RTO has won wide recognition for its excellent performance. Megaunity self-developed RTO has the following significant advantages:

High purification efficiencyAll types of VOCs can be almost completely removed.
high heat recovery rateThe unique structural design makes the heat recovery and utilization to the maximum extent, which greatly reduces the energy consumption.
Flexibility: Support a variety of heating options, including electric drive, combustible gas combustion or direct use of organic solvent itself as a fuel source, can be flexibly adjusted according to the actual situation to meet the needs of different application scenarios.
Self-sustaining operation: When the intake air concentration reaches a certain level, the system can maintain high temperature operation without adding additional auxiliary fuel, further saving costs.

The VOCs waste gas treatment scheme provided by the Megaunity not only solves the environmental pollution problems faced by lithium battery manufacturers, but also saves a lot of operating costs for enterprises. Through careful consideration and optimized design of each link, the Megaunity is committed to creating a cleaner and healthier industrial ecological environment, and helping my country's new energy industry to move towards a greener and environmentally friendly direction.
