Nitrogen Generation Equipment
High Purity Nitrogen Gas Separation Equipment Psa System Low Noise For SMT
I, Nitrogen generator system design
1. Compressed air system
Air compressor supply the raw material air for the nitrogen generator. The nitrogen making system need high quality,stable pressure and enough air consumption.Air compressor should use the reliable, maintenance easily,low noise,screw air compressor.
Remark:We suggest air compressor prepare a spare set,to confirm the produce stable.
2. Compressed air clarification system
Compressed air pass through 9 grade filters,then pass through cooling type dryer.let the compressed air cooling,let the vapour in the air condensation into water,along with dust,oil drain out the machine.It’s better to put the cooling dryer in the compressed room.
After the cooling dryer is the filters,there are two group filters,one is 7 grade main pipeline filters,another is 5 grade high quality oil removing filter.7 grade main pipeline filter precision is 1um,filter out 1um and larger solid state and liquid particle,vestigital oil content 1ppm w/w.5 grade high quality oil removing filter filtrate precision 0.01um,remove 0.01um and larger solid state and liquid particle, 99.9999+% oil,the rest oil content 0.001 ppm w/w. Compressed air quality can reach 1 class according to ISO8573.1. Such clean and dry compressed air can inlet active carbon filter,air buffer tank then inlet nitrogen generator part,after PSA device make out the nitrogen purity ≥99%.
3. Pressure Swing Adsorption Nitrogen making system
Pressure swing adsorption (PSA) is an advanced gas separate technique,it is widely used in gas supply field in the world.
3 .1 Adsorbing material
Adsorbing material is the center part of PSA nitrogen generator,Normally use the the Carbon Molecular Sieve,it can adsorb the oxygen,CO2,water in the air,but can’t adsorb the nitrogen..
3.2 PSA principal
Because O2 and N2 these two gas molecule have diffusion rate difference on the molecule sieve surface,O2 smaller diameter can diffuse faster,most of them inlet micropore of CMS,the large diameter N2 diffuse slowly,less of them can inlet ,use this adsorption difference come true O2 and N2 separate.
All systems are designed for unattended operation and automatic Nitrogen demand adjustment.
Low Electric Energy Consumption
All systems are designed for Energy-Efficient.
Lower Space Requirement and Short installation period
The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and supplied from factory. Tongyue Machinery has own TRUE brand of gas separation equipments.
Installation is very easy and convenient.
Start-up time is about 30 minutes to get desired Nitrogen purity. So these units can be switched ON & OFF as per Nitrogen
Very reliable for continuous and steady operation with constant Nitrogen purity. Plant availability time is better than 98% always.
Molecular Sieves Life
Expected Molecular sieves life is more than 10-years i. e. Whole life time of Nitrogen plant. So no replacement costs.
Simple operation and maintenance
All systems are designed by integrated solution for easy-operation and easy-maintenance.
