Abstract

The invention provides a three-dimensional film spraying and perforating tray belonging to the field of mass transfer and heat transfer equipment in chemical engineering. The three-dimensional film spraying and perforating tray comprises a tower body and a tower plate arranged inside the tower body, and spraying covers arranged on the tower plate. The three-dimensional film spraying and perforating tray is characterized in that a plurality of fixing holes are formed in the tower plate, a guide cylinder is fixed in each fixing hole, a liquid seal trough is arranged at the outer ring of the side wall of each guide cylinder, a gas raising hole is formed at the bottom of each liquid seal trough and is concentric with each fixing hole, the spraying cover is arranged at the inner ring of the side wall of each guide cylinder, the lower end face of the side wall of each spraying cover is welded with the bottom of each liquid seal trough, a plurality of spraying holes are formed in the side wall of each spraying cover, a top cover is arranged at the top of each spraying cover, a liquid receiving trough is arranged at the upper end of each spraying cover, the side wall of each guide cylinder is coaxially connected with the outer wall of each spraying cover and the side wall of each liquid seal trough, gaps are reserved between the side wall of each guide cylinder and the outer wall of each spraying cover and between the outer wall of each spraying cover and the side wall of each liquid seal trough, and a gap is reserved between each top cover and each spraying cover. According to the three-dimensional film spraying and perforating tray, by adopting a perforating technology, on the one hand, the problem caused by liquid streaming and mixing is solved, and on the other hand, the gas-liquid contact time is increased and through perforation, and thus the mass transfer efficiency is increased.

Description

technical field [0001] The invention relates to the field of mass transfer and heat transfer equipment in chemical engineering, in particular to a three-dimensional membrane spray through-flow tray. Background technique [0002] Chinese utility model patent ZL01221920.7 discloses a guided jetting tower. A guided jetting separation plate is installed above the jetting hood to reduce entrainment of mixture foam and improve tray efficiency. Chinese utility model patent ZL01224885.1 discloses a nozzle baffle type tray, in which two separation plates are installed below the gas lift hole to reduce the entrainment of foam. Chinese utility model patent ZL99200122.6 discloses a radial side-guiding injection tray. Guide plates are installed around the injection cover and on the liquid seal cover to prevent liquid back-mixing and reduce tray resistance. Although the above methods have played a role in improving the mass transfer efficiency to a certain extent, the three-dimensional i...
