[0002] A dehydration tower is a tower-type vapor-liquid contact device for distillation, also known as a distillation tower. According to the operating method, it can be divided into a continuous dehydration tower and an intermittent dehydration tower. The basic principle of a dehydration tower is that steam enters from the bottom of the tower and contacts the descending liquid in countercurrent. During the two-phase contact, the volatile components in the descending liquid are continuously transferred to the steam, and the non-volatile components in the steam are continuously transferred to the descending liquid. The closer the steam is to the top of the tower, the higher the concentration of its volatile components, and the closer the descending liquid is to the bottom of the tower, the more concentrated its non-volatile components are, thereby achieving the purpose of component separation. Therefore, the use of high-efficiency dehydration towers is becoming more and more widespread.

[0003] Hydrofluoric acid is a colorless liquid with strong corrosiveness and toxicity. It is an aqueous solution of hydrogen fluoride gas and is widely used in glass engraving, petroleum refining, metal cleaning, organic synthesis, refrigerant manufacturing and pharmaceutical intermediates. After the use of hydrofluoric acid, it is necessary to remove the water from the hydrofluoric acid containing water by a certain method to obtain anhydrous or low-water hydrofluoric acid. In the use process of the existing dehydration tower, the volatile components evaporate as the steam rises, and then, the descending liquid in the existing dehydration tower is in a flowing state, so the contact area of ​​the flowing rising steam is fixed, resulting in a decrease in dehydration efficiency. For this reason, a hydrofluoric acid dehydration tower is proposed. Utility Model Content
