FIELD: gas purification.
SUBSTANCE: invention relates to the field of flue gas purification. A method for controlling the desorption column hot air blower is proposed, which allows controlling the rotation frequency of the desorption column hot air blower, including the following steps: determining the heat exchange coefficient of the desorption column heating section in the current state when the desorption column is operating in a stable state; determining the target control temperature at the outlet of the desorption column heating section and determining the rotation frequency of the hot air blower based on the values of the heat transfer coefficient and the target control temperature at the outlet; starting the hot air blower in operation for a specified period of time with the speed of the blower determined at the previous stage; determining the actual temperature at the outlet of the heating section; when the actual outlet temperature does not correspond to the specified range of threshold values, the following steps are cyclically performed: determining the heat exchange coefficient of the desorption column heating section in the current state; re-determining the rotation frequency of the hot air blower based on the values of the heat exchange coefficient and the target control temperature at the outlet; starting the hot air blower in operation for a specified period of time with a repeated certain speed of rotation of the supercharger; as well as determining the actual temperature at the outlet of the heating section.
EFFECT: ability to accurately control the rotation frequency of the hot air blower in accordance with the target control temperature at the outlet of the heating section.
