The invention relates to a gas phase distribution device of a baffle plate tower. The gas phase distribution device is characterized by comprising an automatic liquid-level control system, a gas distributor, a pressure dropping adjusting plate and a tower plate with gas raising pipelines, wherein the tower plate with the gas raising pipelines is arranged in the baffle plate tower and is located below tower filling; the pressure dropping adjusting plate is located above the tower plate with the gas raising pipelines; the edge of the tower plate with the gas raising pipelines is connected to the tower wall of the baffle plate tower in a sealing manner; gaps are formed at two sides between the gas distributor and the tower wall of the baffle plate tower and between the pressure dropping adjusting plate and the tower wall of the baffle plate tower; the automatic liquid-level control system is arranged between the pressure dropping adjusting plate and the tower plate with the gas raising pipelines and is located on the external of the baffle plate tower; long holes are formed in a baffle plate located between the pressure dropping adjusting plate and the tower plate with the gas raising pipelines; a plurality of openings are formed in an area, located at a prefrationation section of the baffle plate tower, of the tower plate with the gas raising pipelines; and a gas raising pipeline is arranged at each opening.
Description
technical field [0001] The invention relates to the field of rectification and separation of chemical engineering, in particular to a gas phase distribution device of a clapboard tower. Background technique [0002] Distillation is a unit operation with high energy consumption in chemical production. According to statistics, its energy consumption accounts for about half of the total energy consumption in the petrochemical industry. Therefore, the research on energy saving in the distillation process is of great significance. In recent decades, the divided wall column developed based on the fully thermally coupled distillation principle has been successfully applied in industry. The main feature of the partition tower is that there are one or more partitions in the tower, which divide the tower into several independent gas-liquid contact areas or spaces, and each area completes different separation tasks for different key components (mainly controlling this The concentrati...
