Oil Mist Purifier
An oil mist purifier eliminates the airborne particulates produced by CNC and other industrial machines when they use coolants or lubricants. It separates the oil molecules from the air, recovers them for reuse and returns clean air to the shop.
A top-rated industrial oil mist air cleaner protects your people from health risks and keeps expensive equipment running safely and efficiently. Here’s how it works:
3D Impact Principle
An oil mist purifier is an air filter designed to remove fine droplets of oil in the atmosphere created when metalworking fluids are used to cool and lubricate machines. These aerosols, called oil mist, can be harmful to health if inhaled. Air pollution also lowers productivity and can damage equipment. An oil mist separator filters out these particles, allowing for safe workplaces and efficient production.
An industrial oil mist separator uses a 3D impact process to oil mist purifier separate and recover up to 70% of the oil molecules in the atmosphere. The system can recycle the recovered oil and return pure air to the workspace. This reduces maintenance costs, helps preserve the environment and protects machinery.
The first layer of the air filter is a stainless-steel woven mesh that prevents iron chips from disrupting the oil mist separator machine. It can also help prevent the abrasion of the oil mist collector, which increases its service life. The second layer is a filtration material that uses progressively structured, non-breaking fibers to trap the oil droplets and coalesce them together. The oleophilic and hydrophobic properties of the filter material determine the effectiveness of this stage.
The third and final stage is a HEPA filter that filters out the remaining particulates. The oleophilic and hydrophobic characteristics of the filter again determine the effectiveness of this stage. The filter can be cleaned and reused to ensure consistent filtration performance.
Circular Pleated Filter Material
Using the 3D impact principle, the air is filtered through a thick filter of various grades of woven stainless-steel fibers. The fibers are randomly arranged to create irregular collisions that help the oil mist adhere to the filter, with the result being that it can be collected. The filter can be easily cleaned to extend its service life.
The air then goes through the second filter stage, which has a cyclone flow pattern that increases its collection efficiency. Here the contaminated air will be further separated into its component parts – the adsorbent oil and gaseous particles. This allows the oil to be recovered for reuse, while the clean air can be returned into the workshop.
An oil mist separator is the ideal solution for metalworking environments. It is important to keep the environment clear from oil droplets in order to guarantee the safety of employees, avoid unplanned disruptions and maintain production efficiency.
It is also essential to ensure optimal results in the work process and protect expensive capital machinery and products from contamination. In addition, prolonged or repeated exposure to the oil products can be harmful to health.
Cyclone Flow Pattern
The present invention provides an air cleaning system with a cyclone, which consists of a collection portion formed on a central position thereof and a plurality of guiding portions radially extending from the collection portion. The system further includes a bottom cover having a through orifice defined on a central position thereof and a conical filtering assembly. The bottom cover has a lower diameter than the collection portion. The guiding portions form an inner zone of the cyclone wherein a flow pattern differs depending on the size of the collection portion’s vortex finder. In particular, a distinct top zone of oil mist purifier relatively low velocity is observed in cyclones with a larger (cyclone IV) or smaller (cyclone V) outlet diameter. This is caused by the fact that the size of the inner vortex finder influences the way the cyclone’s inlet guide channels influence the entrance velocity into the main body of the cyclone.
This is an important aspect of a cyclone separator’s performance and, in particular, its minimum filtered particle size. This is the minimum particle size above which a cyclone can remove particles from a gas stream with a measurable efficiency. Typically, the actual efficiencies of a cyclone are much higher and depend on many other characteristics of a specific cyclone’s geometry and operating flow rate as well as gas and PM properties.
HEPA filters are the most effective air filters available. They meet and exceed high standards set through the United States Department of Energy and help to trap and prohibit particles as small as 0.3 microns from being exhausted or released back into your facility’s air by an air cleaner.
Particle pollutants include allergens such as mold spores, pet dander and dust mites. They also include irritants like smoke and other particulate matter. Inhaling these particles can lead to health issues, such as asthma and other respiratory problems. Often, they can even lead to infection.
A HEPA filter works in four different ways to trap these particles. First, the air flow carries a particle between two fibers and is sieved. Then, inertia causes the particle to collide and stick to the fiber. Finally, diffusion causes the particle to splinter into smaller particles, which are more easily trapped.
Nederman solutions for oil mist eliminator utilize a special HEPA filter designed to separate oil, coolant and other liquids from air in continuous operations. The filter media is made of PTFE or glass fiber, arranged as a mat of randomly positioned strands. This filter is ideal for separating and collecting oil mist, cooling oil and grinding dust. In addition to its high efficiency, the patented HEPA Filter provides long filter media life and reduced energy consumption.
