PSA Nitrogren Generator for 20ft and 40ft CA Cold Container
Pressure Swing Adsorption Nitrogen Generator
2, Functional Principle
1. Air compressing system, this system includes air compressor, air buffer tank, the purpose of this system is to compress the normal pressure air to high pressure air.
2. Air purification system, this system includes degreaser, refrigerated(adsorption)dryer,ultrafilter,active carbon filter,the purpose of this system is to remove dust,water and oil in the compressed air to make sure the compressed air will be clean and dry in the following steps.
3. Air buffer tank. This system includes air compressing buffer tank,the purpose of this system is to store the compressed gas to make sure the stable supply of gas for O2/N2 separation system,mainly composed of air tank and valves.
4. Adsorption separation system,this system includes adsorber tower,Program control valve,controller,analysis meter, also this is the most important system for all the production line, the purpose of this system is to produces N2 through PSA technology,composed of two adsorption towers filled with carbon molecular sieve and automatic control valves.
PSA nitrogen technology utilizes two towers which are filled with carbon molecular sieve (CMS). Compressed air enters the bottom of one tower. While the smaller oxygen molecules are adsorbed by the CMS, the larger nitrogen molecules pass through the sieve and are stored. Once the CMS of the working tower is saturated with oxygen, the regeneration of the CMS in the tower starts to work by depressurizing, and while another tower is switched to start the process over again.
5. Buffering and emptying system,this system includes Nitrogen gas buffer tank,filter,pressure regulating valve,flow gauge, emptying system.the purpose of this system is to store the finished N2 and regulate the pressure for the request,and change the flow of the N2.
