What is the principle of stripping?
1 Answers
By allowing wastewater to come into direct contact with water vapor, volatile toxic and harmful substances in the wastewater diffuse into the gas phase in a certain proportion, thereby achieving the goal of separating pollutants from the wastewater. The following is relevant information: 1. The function of stripping: It is a unit operation used to recover absorbed solutes and separate the absorbent from the solutes for regeneration. 2. The principle of a stripping tower: Utilizing the fact that contaminated condensate water from evaporators and cooking devices contains methanol and degraded organic sulfides that are more volatile than water, the contaminated condensate water and steam come into contact on the trays inside the stripping tower. The condensate water flows horizontally along the trays, while the steam flows vertically upward through the holes on the trays. In the steam leaving the trays, the concentration of volatile compounds is higher. Correspondingly, the concentration of volatile components in the condensate water leaving the trays is lower than when it entered. The contaminated condensate water stripping device includes a stripping tower, feed preheater, overhead condenser, and equilibrium condenser.
