Embodiment Construction
[0033] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0034] A rectification tower for improving heat and mass transfer performance, with a tower height of 10 meters and a tower diameter of 2 meters, including 40 rectification tower trays, and all rectification tower trays are arranged along the same vertical line. Such as figure 1 As shown, the rectification column tray includes a tray body 1, the tray body 1 is a spiral structure, the top is provided with a liquid inlet 2, and the bottom is provided with a liquid outlet 3, and the upper rectification column tray The liquid outlet is connected with the liquid inlet of the next rectification column tray.
[0035] The helical diameter of the helical structure gradually decreases from the middle to both ends, presenting a top shape in three-dimensional space. Each tray unit is composed of 8 spirals, the diameter of which increases gradually along the heigh...
