Detailed Product Description:
Oxygen Generator Capacity :
90% - 95%
Energy consumption of equipment :
VPSA Oxygen Gas Generation Maker
Compenents of VPSA Oxygen Generator
Air Fan and Vacuum Pump :
Air fan provide air source for the whole system. Based on VPSA oxygen
generator design condition and customer requirements, fan with proper outlet
air pressure is to be provided. Vacuum pump ensures correct system operation
and keeps the system in ideal vacuum state, which ensures equipment
constantly adsorb nitrogen and produce oxygen.
Temperature Regulating System :
Air temperature regulating system is made up of a water cooler and an
electric heater. The temperature of air compressed by fan is around 70 deg.
Cent , passing the water cooler, its temperature is reduced to meet the
requirements of process operation. Then it is sent into the adsorption
towers. In winter, the temperature of air is to be increased by the electric
heater and reaches the requirements of process operation.
Adsorption System :
The adsorption system mainly consists of two towers filled with zeolite
molecular sieve adsorbents and piping valves etc. Air enters into the bottom
of one tower, when passing through the adsorbent layer, N2
oxygen, Vapor are adsorbed by molecular sieve and oxygen passes through the
adsorbents and gathers at the top of tower, flowing out as produced gas,
meanwhile the other tower is in the process of regeneration. When the
adsorbing tower almost reaches saturation, by the operation of control
system, the processing air flows into the regenerated tower and begins to
produce oxygen.Two towers alternately adsorb and constantly produce oxygen .
Oxygen Buffer Tank :
Compared with three-tower process, oxygen generator with two towers can not
produce consecutive oxygen, therefore, a buffer tank with large volume is
needed for stable oxygen output.
Control System :
Technical Specification :
- System process is achieved by DOS control system. In this system,
valves switches are independently controlled by PLC (Programmable Logic
Controller). Analog signals of test sensors communicate with the main
control system through specific communication protocols. Relevant data
of specific unit can be sent to main control system and remote control
signals of main control system can be accepted by specific unit.
- In order to ensure safe oxygen supply, functions of interlink,
protection, alarm, print, record etc can be provided.
- The output variation of oxygen supply can be adjusted by DCS control
system. System operating parameters can be adjusted to save energy.
- The main control system adopts industry computer, provided with
specific software and convenient human-machine touching screen,
Start/stop and operating parameter collection can be realized on control
panel. Remote monitor and print of running status record can be easily
||200-500 Nm3 / hr
- Quick and convenient start and stop
- Low investment and energy consumption
- High automation
- Simple operation and maintenance
- Short installation period and small ground treatment workload
