NMP & Heat Recovery
NMP treatment system can achieve the purpose of energy saving and consumption reduction, NMP treatment and gas purification of the air supply and exhaust system, through heat recovery, dehumidification and filtration.It can meet the requirements of temperature, cleanliness, NMP concentration and pressure in the oven during the coating and drying process of lithium battery production. In order to prevent NMP leakage, it is necessary to strictly control the air tightness of pipes and equipment.
Solutions
Megaunity NMP and waste heat recovery device achieve energy conservation and consumption reduction of ventilation system, NMP purification through heat recovery, dehumidification, and filtration, meeting the requirements of temperature, cleanliness, NMP concentration and pressure inside the oven during the coating and drying process in the cathode electrode production of lithium batteries.
Megaunity independently developed modular unit can achieve precise control of the NMP concentration inside the oven by automatically adjusting the exhaust air volume according to the change in NMP concentration inside the oven, reducing the circulating air volume, and saving more than 30% energy compared to existing technologies.
Product Advantages
• Revolutionary new product manufacturing process, with heat recovery efficiency reaching up to 90%.
• Meet European emission standards ≤1mg/m³.
• Highly modular integration for rapid assembly.
• Low operational energy consumption, high recovery purity, and notable return on investment.
NMP Recovery System Exhaust Gas Purification Equipment
Modular Processing Unit for Negative Electrode
The high-temperature and high-concentration NMP gas emitted from the coating oven has undergone heat recovery and NMP recovery through heat exchangers, cooling and condensers, with approximately 90% of the air returning to the oven. The remaining 10% undergoes adsorption purification using molecular sieve wheels to reach emission standards for NMP concentration before being released into the atmosphere.
Megaunity's double rotary wheel exhaust gas purification device meets the emission standards of Europe and the United States. After the first-stage rotary wheel adsorption purification, it undergoes secondary rotary wheel deep adsorption purification, reducing the NMP content in the exhaust gas to ≤1 mg/Nm³ for standard discharge. The overall purification rate of the system can reach 99.7%.
The NMP recovery system uses Megaunity developed high efficiency heat exchangers, allowing the high temperature gas emitted by the coating machine to undergo heat exchange with the low temperature gas after NMP condensation treatment, maximizing the recovery of emitted heat energy. The heat exchange efficiency can reach up to 90%.
