What is the working principle of a stripping tower?
1 Answers
The working principle of a stripping tower: Inside the stripping tower, contaminated condensate comes into contact with steam on the trays. The condensate flows horizontally across the trays, while the steam moves vertically upward through the holes in the trays, resulting in a higher concentration of volatile compounds. Correspondingly, the concentration of volatile components in the condensate leaving the trays is lower than that entering the trays. The contaminated condensate stripping device includes a stripping tower, a feed preheater, a top condenser, and a balance condenser. Below is an extended introduction: 1. The function of the stripping tower: It is used to recover the absorbed solute and separate the absorbent from the solute to achieve regeneration. 2. The form of the stripping tower: It can be a plate tower or a packed tower. Regardless of the form of the tower, the feed enters from the top of the tower and exits from the bottom; the desorbent enters from the bottom of the tower, countercurrently contacts the liquid feed inside the tower, and exits the tower together with the stripped components at the top.
