Problems solved by technology
Plate towers are widely used in petrochemical, chemical, brewing, pharmaceutical and other industries, but these traditional plate towers have insufficient energy efficiency
Especially when the industrial production capacity increases or decreases, the pressure drop changes greatly, it is difficult to automatically adjust the tray, and the tray is easily blocked, which makes it difficult to adjust the entire distillation column to an economical energy efficiency level, resulting in energy waste and subsequent equipment maintenance. rising costs

The invention relates to a composite rectifying tower plate. The composite rectifying tower plate comprises a plate body, wherein the plate body is provided with more than one hollow cavity which is protruded upwards, an opening is formed in the bottom surface of the hollow cavity, and a plurality of water through holes are formed in the side surfaces of the plate body and the hollow cavity. The composite rectifying tower plate is characterized in that more than one large vent hole is formed in the top surface of the hollow cavity, each large vent hole is respectively covered with a large top plate, and one side edge of the large top plate is hinged to the top surface of the hollow cavity.
Description
technical field [0001] The invention relates to a rectification tower, in particular to a composite rectification tray. Background technique [0002] Tray tower is a large class of separation equipment widely used in industry at present. Plate towers are widely used in petrochemical, chemical, brewing, pharmaceutical and other industries, but these traditional plate towers have insufficient energy efficiency. Especially when the industrial production capacity increases or decreases, the pressure drop changes greatly, it is difficult to automatically adjust the trays, and the trays are easily blocked, which makes it difficult to adjust the entire distillation column to an economical energy efficiency level, resulting in energy waste and subsequent equipment maintenance. rising costs. Contents of the invention [0003] The object of the present invention is to provide a compound rectification tray capable of automatically adjusting the pressure drop and improving the effic...
