Abstract
The utility model relates to an internal structural component for distillation, absorption and other vapor-liquid mass transfer processes, in particular to a plate-type tower fixing valve element which can effectively increase the gas-liquid two-phase contact surface area. The fixing valve is formed by punching a tower tray by one time and comprises a valve cover and four supporting feet which are averagely distributed at an angle of 90 degrees annularly; the shape of the valve cover and the section shape of a valve hole on the tower tray are crosses which are formed by two orthogonal rectangles; the valve cover and the edges of the supporting feet are punched into semicircular arc toothed structures; and a tongue-shaped guiding hole is formed above the valve cover. Through the adoption of the structure, the wetting edge of the fixing valve is larger, and an outlet of a gas passage is larger on the premise of ensuring the same opening area of the tower tray, so as to effectively increase the gas-liquid two-phase contact surface area and strengthen the mass transfer; and furthermore, through the unique cross-shaped orthogonal structure, an aim of improving the liquid phase flowability of an arched area of a plate-type tower can be achieved by changing the included angles of the normal planes of the two opposite supporting feet of the fixing valve and the liquid flowing direction.
