The present invention discloses a gas distribution structure for a distillation column. Pressure drop adjusting column tray assemblies are arranged in a left mass transfer region and a right mass transfer region along a column height direction. The gas distribution structure includes column trays, gas-rising pipes, downcomers and cover hoods, wherein a gas flow meter is arranged in a pipe of any gas rising pipe; a feeding port and a liquid collecting port are formed in a column wall; a liquid flow meter, an adjusting valve and a circulation pump are arranged on a circulation pipeline between each liquid collecting port and each feeding port; technological parameters are transmitted to a control system; and the circulation pumps and the adjusting valves are controlled by the control system
