Distillation tower lift tray

The operating stability range is wide. There is little pressure loss. Distillation column lift tray.

The "lift tray" is a tray with an automatically adjustable opening ratio due to its lift mechanism, resulting in low pressure loss and a wide stable operating range. The tray element consists of a fixed perforated plate, a movable perforated plate, a stop for the movable perforated plate that also serves as a lift upper limit stop, and a casing. The opening ratio ranges from 0 to 20% at no ventilation (minimum opening ratio) and from 20 to 60% at maximum lift (maximum upper opening ratio), with hole shapes including round, square, triangular, and elongated. The diameter of the holes, opening ratio, and hole shapes are designed based on the processed material, operating conditions, and intended use.

basic information

**Main Features** - The lift mechanism automatically adjusts the opening ratio, resulting in low pressure loss and a wide stable operating range for the tray. - The tray element consists of a fixed perforated plate, a movable perforated plate, a stop for the movable perforated plate that also serves as a lift upper limit stop, and an outer casing. - The opening ratio ranges from 0-20% at no ventilation (minimum opening ratio) to 20-60% at maximum lift (upper limit maximum opening ratio). - The diameter of the holes, opening ratio, and hole shape are designed based on the processed material, operating conditions, and intended use. **Other Features** - Wide operational stability range → The lift mechanism automatically adjusts the opening ratio, allowing for complete continuous operation within an air tower speed range of 0.5 m/s to 3.0 m/s. - Low pressure loss → Shows almost constant values across a wide range of air tower speeds. → Pressure loss of 15-20 mm water column is not significantly different compared to packed towers. - High processing capacity → Processing capacity can be increased by more than twice compared to conventional trays. - High efficiency → The two perforated plates cause bubble re-distribution, increasing the contact surface area and ensuring sufficient gas-liquid contact. - Simple structure and easy maintenance → Does not require a downcomer, making it very easy to manufacture due to its simple structure. ● For more details, please download the catalog or contact us.
