How to deal with the reason why alkali can’t get in during mixed bed regeneration

Reasons:

  • The liquid level of the alkali metering tank is low;
  • The outlet door of the alkali metering tank is not opened;
  • The alkali inlet door of the mixed bed is not opened;
  • The alkali injector is defective;
  • The alkali pipeline is crystallized;
  • The level gauge of the alkali metering tank is faulty;
  • The alkali concentration meter is faulty;
  • The nylon mesh sleeve of the alkali main branch pipe into the mixed bed is fouled.

Treatment:

  • Check whether the actual level of the alkali metering tank is consistent with the level gauge of the alkali metering tank to ensure that the level of the alkali metering tank is normal;
  • When alkali is introduced, all the valves that should be opened are opened, such as valves If it is not open, contact the mechanical and electric control maintenance personnel for processing;
  • Contact mechanical maintenance personnel for all pipeline defects.
