Detailed description of the invention
As it is shown in figure 1, a kind of swing adsorption nitrogen producing apparatus, including air tank 1, pressure-variable adsorption
Nitrogen making machine 4 and nitrogen pot 5, air tank 1 delivers the air to varying-voltage adsorption nitrogen machine 4 to be carried out
Nitrogen processed processes and the nitrogen made is stored in nitrogen pot 5.It is positioned at varying-voltage adsorption nitrogen machine 4 He
It is provided with pressure transmitter 6 on pipeline between nitrogen pot 5, is positioned at air tank 1 and transformation is inhaled
Controlled intake valve 2, described pressure transmitter 6 it is provided with on pipeline between attached nitrogen making machine 4
All it is connected with PLC control system 3 with described intake valve 2.
Further, except being provided with air intlet, air outlet slit and sewage draining exit on described air tank,
The pressure controller one for measuring its internal pressure, described pressure control also it is provided with at its top
Device one processed is connected with PLC control system.Except being provided with nitrogen inlet, nitrogen on described nitrogen pot
Gas outlet and sewage draining exit, be also provided with the Stress control for measuring its internal pressure at its top
Device two, described pressure controller two is connected with PLC control system.
Further, in order to ensure the nitrogen temperature that varying-voltage adsorption nitrogen machine is made, Ke Yi
It is enclosed with heat-preservation cotton on pipeline between varying-voltage adsorption nitrogen machine and nitrogen pot.
The technical program adds a pressure transmitter 6 on nitrogen outlet pipeline, according to user's gas
Pressure limit arranges upper and lower bound, and pressure transmitter 6 exports 4-20mA signal and controls to PLC
System processed, when nitrogen outlet pipeline pressure is higher than the upper limit, PLC plug-in break-off, PLC
Plug-in controls intake valve 2 and is closed, and varying-voltage adsorption nitrogen machine no longer consumes compression
Air and output nitrogen, when nitrogen outlet pipeline pressure is less than lower limit, PLC plug-in is extensive
Multiple normal work, continues with compressed air output nitrogen until pressure reaches the upper limit, circulation industrial
Make.
Above-described is only preferred implementation of the present utility model, it is noted that for this
For the those of ordinary skill in field, on the premise of creating design without departing from this utility model,
Can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
