一种蒸馏用斜孔塔盘
摘要：
本实用新型提供了一种蒸馏用斜孔塔盘，包括受液盘，受液盘上设置溢流堰，受液盘上开设多个舌孔，每个舌孔一侧均设置舌板，舌孔一侧的舌板包括倾斜舌板和水平舌板，倾斜舌板一端与受液盘连接，倾斜舌板另一侧与水平舌板连接，水平舌板与受液盘平行，倾斜舌板与受液盘之间的夹角α的角度为15°-30°，各舌孔在受液盘上排列成多列，每一列均与溢流堰的长度方向平行，受液盘上舌孔的列数为3的整数倍。本实用新型能够有效提升气液两相的接触效率，缩短气液两相达到平衡所需的时间，气流的阻力仍保持在相对较低的水平。
摘要（英）：

The utility model provides an inclined hole tray for distillation. The inclined hole tray comprises a liquid collection tray, wherein an overflow weir is arranged on the liquid collection tray; multiple tongue holes are formed in the liquid collection tray; a tongue plate is arranged on one side of each tongue hole; the tongue plate on one side of the tongue hole comprises an inclined tongue plate and a horizontal tongue plate; one end of the inclined tongue plate is connected with the liquid collection tray; the other side of the inclined tongue plate is connected with the horizontal tongue plate; the horizontal tongue plate is parallel to the liquid collection tray; an included angle alpha between the inclined tongue plate and the liquid collection tray is 15-30 degrees; the tongue holes are arranged in multiple columns on the liquid collection tray; each column of the tongue holes is parallel to a length direction of the overflow weir; the column number of the tongue holes in the liquid collection tray is integral multiple of 3. According to the inclined hole tray for distillation, the gas-liquid two-phase contact efficiency can be effectively improved, the time needed for achieving gas-liquid two-phase balance is shortened, and the airflow resistance is kept on a relatively low level.
