Working
principle:
Hydrogen containing gas
mixture into the PSA adsorption tower, the adsorption bed adsorbent on
adsorption capacity of each gas mixture in the with the change of pressure
difference, pressure when the adsorption of impurities in the raw material gas,
is not easy to absorb the components of hydrogen from the outlet end of the
adsorption bed as the product output, decompression. The adsorption of
impurities The components were desorbed and desorbed while the adsorbent was
regenerated. At least four adsorption beds are used to achieve continuous
hydrogen output。
Control
mode and characteristics:
Control
mode: The SPA device is
controlled by the controller and meter. The controller can select DCS, FCS and
PLC control system according to the scale and control requirements of the SPA
device。
Characteristics: It not only realizes the conventional control of the system, but also
realizes the expert control and adaptive optimization control of arbitrary
combination and switching of multiple towers, which not only improves the
operational flexibility of the device, but also ensures the long-term, stable
and safe operation of the PSA device。
