Distillation tower is an important mechanical equipment for distillation tower work, which is selected in the production and manufacturing of petroleum and chemical enterprises. According to the chemical reactions of distillation tower, new compounds will be generated, many of which contain air pollution sources and can have adverse effects on the geographical environment without treatment. Therefore, to maintain the treatment of this gas, the sewage treatment of distillation tower must be maintained first.
In the manufacturing of petrochemical equipment, continuous sewage treatment is widely used. The professional capabilities of distillation towers are applied to carry out simple technological transformations with minimal investment projects, thereby extracting condensable and non condensable substances, recovering condensable organic matter to 99 ℃, and ensuring the basic moisture content of organic waste gas to maintain the resource regeneration of VOCs in environmental monitoring.
The extensive gas-liquid contact of the distillation column can be divided into foam plastic contact and eruption contact. When the gas velocity rises again, the number of bubbles increases, and bubbles cause collision and cracking. At this time, most of the liquid on the board exists in the middle of the bubbles by means of boundary layer, resulting in some dynamic foams with smaller diameter. Because the total area of the foam touch is large, it is a very good touch situation.
And when the gas velocity rises again, the liquid on the plate is coated with liquids of different sizes. The liquid with a very large diameter falls back onto the tray under the interaction force, while the liquid with a smaller diameter is carried away by the gas, causing liquid droplets to be carried away. The liquid returns to the tray and is dispersed again. This type of liquid continues to cause and accumulate, increasing the heat transfer area for a wide range of flows, which is a very good contact situation.
