The absorption tower device is a core environmental protection equipment for realizing gas-liquid mass transfer reactions, mainly used in industrial waste gas treatment, pollutant absorption, and energy recovery scenarios. Here is a summary of its key information:

1、 Basic types and structures

1. ‌Classified by contact form‌

• ‌Packing absorption towerGas liquid counter current contact on the packing surface, high mass transfer efficiency, suitable for low concentration and atmospheric treatment

• ‌Plate towerStep by step contact through trays, such as sieve tray towers and bubble cap towers, suitable for high liquid to gas ratio conditions

• ‌Spray tower/Venturi towerLiquid is dispersed in the gas phase as droplets, with a simple structure but high energy consumption

2. ‌typical structure‌

• Including tower body, packing layer, spray system, defogging device and liquid sealing device (such as U-shaped pipe or liquid sealing tank)

• The material can be selected from carbon steel, PP or stainless steel, and anti-corrosion design is required

2、 Core functions and design points

1. ‌function‌

Distillation tower is the core equipment for component separation in chemical production, which purifies the mixture by boiling point difference through gas-liquid mass transfer. Here is a summary of its key information:

1、 Basic Structure and Types

1. ‌core component‌

• Including the distillation tower body, reboiler (providing rising steam), condenser (generating reflux liquid), and reflux ratio control system.

• The tower is divided into a distillation section (upper purification of light components) and a distillation section (lower concentration of heavy components).

2. ‌main types‌

• ‌Plate towerSuch as sieve plate tower and float valve tower, which are suitable for high liquid to gas ratio conditions by gradually contacting the trays.

• ‌packed columnGas liquid counter current mass transfer on the packing surface, high efficiency and low pressure drop, suitable for laboratory or small-scale production

2、 Working principle

• Separation is achieved by utilizing the difference in boiling points of components through multiple partial gasification (reboiler) and condensation (condenser) processes

• Reflux ratio control is a key parameter that affects separation efficiency and energy consumption

3、 Application and Optimization

1. ‌industrial applications‌

• Methanol distillation, ethanol recovery, etc

• The commonly used glass distillation tower in the laboratory supports operations such as vacuum distillation and reflux ratio control

2. ‌technology upgrade‌

• AI optimization model can adjust parameters in real-time

4、 Market and Equipment

• The price range of laboratory equipment is wide (such as ¥ 23000~68000), and materials can be selected from glass or stainless steel

• Industrial grade non-standard customization needs to consider tower internals design and anti-corrosion requirements
