The mass transfer process of the new vertical sieve tray, which uses the gas phase as the continuous phase and the liquid phase as the dispersed phase, is as follows:: 1. The liquid is lifted, pulled, broken, and broken. 2. The gas and liquid hit the top of the cover, turn back, and are sprayed. The gas and liquid are violently turbulent and mixed in the cover, and the liquid surface is constantly updated. 3. The gas and liquid are ejected from the cover hole, and the liquid is dispersed into droplets, providing a larger mass transfer surface area for gas-liquid contact. 4 .The liquid droplets fall back to the tray, and the gas rises into the upper tray. The vertical sieve trays are also known as radial side guide injection trays, vertical mass transfer trays, three-dimensional space mass transfer trays, New-vst, new-VST, New-VST, new vertical sieve trays, etc., which are all one type. There are round caps, square caps, rectangular caps, trapezoidal caps, and pagoda-shaped caps. The names are different, but there is no obvious difference in essence. The vertical screen plate technology was first invented by Mitsui Company of Japan, and the latest introduction in China was Hebei University of Technology. For pictures of vertical screen plates, please refer to the company website Tangshan Honglin Technology Co., Ltd.
