Product Description
Product ParameterPrinciple picture
Product DescriptionTheory After the exhaust air in the process of anode coating passes through the heat exchanger, and then after the cooling water at room temperature and the chilled water at low temperature are condensed at the second level, more than 90%~95% of the winds with NMP content<280PPM pass heat exchanger and warmed up and then return to the coating machine, And the remaining 5%~10% or so of the exhaust winds are discharged at high altitude after being treated by the rotor absorbing and the concentration of NMP is reduced below the permissible environmental protection emission concentration. The recovered NMP flows into the waste liquid storage tank, The equipment is fully automated. Not only can maintain high-efficiently NMP and heat recovery, but meeting the safe and efficient operation ofthe coating machine and national andlocalenvironmentalrequirements.
Highly-Efficient NMP Recovery System(Overviews)
NMP rotor recycling, equipment is a kind of environmental protection equipment specially designed for there covery of NMP (N-methylpyrrolidone). This type of equipment usually adopts a rotor-type structure, utilizinga combined structure of a cooling, system, a special rotor and a regeneration system to achieve solvent recovery and treatment of NMP exhaust gases of various air volumes to meet emission standards.NMp is a common organic solvent, widely used in lithium batteries, electronics, pharmaceuticals and other fields.However, the treatment and recovery of NMP exhaust has always been a difficult problem. Traditional treatment methods are often inefficient and prone to secondary pollution. The emergence of NMP rotor recovery equipment provides an effective solution to this problem.In addition, NMP rotor recycling equipmentis environmentally friendly and reliable.The equipment is able to convert waste into renewable resources.reducing the pollution of waste to the environment, in line with environmental requirements. Under longterm stable operation, the equipment has a long lifespan and is highly reliable. in conclusion, NMP rotorrecovery equipment is an efficient, environmentally friendly and safe equipment, which can effectively recover and treat NMP waste gas and make positive contributions to industrial production and environmental protection.
Heat exchanger
Heat exchanger , is a device used to transfer heat from one medium to another, occupies an important position in the chemical industry, petroleum, power, food and many other industrial production. The advantages of heat exchangers mainly include high efficiency, energy saving, safety, reliability and easy maintenance,etc. Compared with the traditional heating and cooling methods, heat exchangers can achieve more precise temperature control, energy saving and cost reduction to improve production efficiency.
Research and Development Background
As the core of the heat transfer field, heat transfer technology plays an important role in many fields such as industrial production, energy use and environmental protection. With the continuous development of industrialization and urbanization, the cost of energy use has risen sharply. Lithium battery coating machine heating requirements of energy consumption in the entire process accounted for a large portion, if the heat exchanger improve efficiency of each 1%, can greatly savethe operating costs ofthe coating machine.
Process
We upgraded the original heat exchanger core by deep disassembling and analysing the core style,runner structure, heat exchanger fins, etc. By changing the flow direction of the air ducts, we achieved that the hot and cold runners flow in the opposite direction to each other and the wind resistance of the two runners can be the same, After continuous simulation and analysis, and testing of small air volume samples, Our heat exchanger has achieved 90% high efficiency heat transfer rate, leading industry, andit is achieved on mass production.
Rotor adsorption theory
VOCs is the acronym of Volatile Organic CompoundS (VOLATILEORGANIC COMPOUNDS), following s02Freon, the pollution of VOCs has become another focus of attention for countries around the world.With the continuous development of new energy lithium industry, lithium battery production process contains a high concentration of exhaust gas,which needs to be purified to meet the emission standards. For example, china's VOCs emission standard is 12.5PPM (50mg/m'), if the exhaust gas isprocessed by the NMP rotor recycling equipment, the treated exhaust gas can meet the domestic and international emission standards (specific reference to the battery industry pollutant emissionstandards GB-304842013).
The rotor is divided into three zones, namely, treatment area, regeneration area, preheating area. NMP gas adsorption through the treatment area, After that the NMP concentration from 280PPM down to5PPM and then directly discharged to the atmosphere. At the same time there is a small amount of wind to provide for the regeneration of the rotor to use, the treatment area after adsorption to there generation area, the adsorption of NMP gas inside the rotor through the principle of heating and drying out ofthe concentration, and then after condensation into a liquid discharged to the storage tankAfter the regeneration of the rotor is completed, it is transferred to the preheating area to recover there sidual heat after regeneration. The air in the preheating zone is taken from the air after the treatment,which can improve the processing efficiency of the runner due to the low content of NMP gas after treatment, After the preheating zone, the rotor is transferred to the treatment zone, forming a cycle. Asthe VOCs rotor continues to circulate, the NMP gas is continuously treated and discharged. The VOCs content can be as low as 1PPM (depending on the regeneration temperature and airflow) after treatmentwith a single rotor.Local structure of equipmentProduct Advantageheat exchange efficiency is up to 90%,NMP recovery rate is ≥99.9%,NMP recovery concentration is ≥90%,The ability to handle NMP emissions can reach below 1ppm,digital control.
1.With a high heat exchange rate, the current heat exchange efficiency has reached 90% through independent research and development, significantly saving on the operating costs of the coating machine.
2. The NMP recovery efficiency is high, able to recover 99.9% of NMP, and the recovery concentration can also reach over 90%.
3.The equipment is highly stable, with 304 stainless steel plates as the material, self-developed welding equipment, and beautiful molding. Various detection and prevention measures have been adopted. For example, pipelines are reserved at places where NMP is likely to precipitate, and each equipment with NMP precipitation is equipped with a liquid receiving tray. Differential pressure gauges are set at necessary parts for real-time monitoring.
4. Digital control, with high freedom. Various operating conditions are visually displayed. You can clearly understand the operation status of the equipment, saving you time and effort.FAQ | FAQ |
