Working principle:
Membrane separation nitrogen equipment is a kind of device that uses gas-permeable membrane technology to produce nitrogen. It delivers compressed air or other gas mixtures to a specially designed membrane module and realizes the separation of nitrogen from other gases (mainly oxygen) by utilizing the difference in diffusion rates of different gases in the membrane material. This kind of equipment is widely used in industries such as chemical engineering, petroleum, electronics, food processing, medicine, and metal processing
Membrane separation nitrogen equipment completes this separation process by using membrane sheets composed of tens of thousands of hollow polymer fibers. These fibers, with their special structure, only allow oxygen and the residual water vapor in the air to pass through the fiber walls. This process is called “permeation“. After oxygen passes through the fibers, it is discharged from the membrane chamber and then released to the outside or a safe area. Nitrogen remains in the hollow fibers and awaits collection at the gas outlet. By removing water vapor, the produced nitrogen is very dry, which is also an advantage for some professional applications.
Advantages:
- Saving energy through purity adjustment: The membrane separation nitrogen generator allows customers to set the specific purity required for their application, ranging from 95% to 99.5% (if the required purity is higher than 99.5%, the PSA nitrogen machine is not a more efficient choice). Through setting a reasonable nitrogen purity allows most users to control their energy consumption and expenses.
- Stable quality: Membrane separation nitrogen generator provides a continuous supply of pure and stable nitrogen gas for the production process and production quality.
- Low maintenance requirements and long service life: Membrane separation nitrogen generator has the advantage of simple construction. The separation process minimizes maintenance requirements because it has no moving parts. This also allows the membrane separation nitrogen generator to operate reliably in areas of high vibration.
- Space saving: The membrane separation nitrogen generator takes up little space, is very quiet during running, and can be installed directly in the production shop.
- Easy to operate: The startup and debugging process is quick and simple.
