Liquid-collecting energy absorption device

Abstract

The invention relates to a liquid-catching power absorber. It comprises liquid-catching power absorbing plate and annular mounting plate; said liquid-catching power absorbing plate includes upper layer liquid-catching power absorbing plate 1 and lower layer liquid-catching power absorbing plate 2, between two said plates equipped with a annular plate 6, the upper of upper layer liquid-catching power absa orbing plate is connected with upper layer annular plate 3, while the one at lowe layer iconnected with lower layer annular plate 5; supporting stand 4 is installed on lower layer annular plate 5, the other end of supporting stand is welded on tower wall. The liquid-catching power absorber greatly reduces flowing speed of gas from circulating gas distributor, eliminates impact to liquid surface in tower bottom by gas and entrainment, and the liquid in gas is catched by said two liquid-catching power absorbing plate, which avoids back-mix-flow and increases operating efficiency.

Description

technical field [0001] The invention relates to an internal part of a rectification tower, in particular to a liquid-catching energy absorber. technical background [0002] In the departments of oil refining, petrochemical, fine chemical, food, medicine and environmental protection, towers are important unit equipment with a large volume and wide range, and their investment generally accounts for about 20% of the total investment, and some even as high as 50%. Columns are widely used in unit operations such as distillation, absorption, extraction, washing, and heat transfer. Therefore, the research on towers has always been an important issue that scholars at home and abroad have generally paid attention to. [0003] With the development of tower equipment, the technology of tower internals has also been continuously developed and improved. Various new structures of tower internals emerge in an endless stream, especially the continuous improvement of gas distributors has fu...

Problems solved by technology

[0004] However, after being applied in various large-scale towers in recent years, it is found that although the double tangential circulation gas distributor can obviously improve the initial distribution of the gas entering the tower, the high-speed gas entering the tower in the horizontal direction passes through the double tangential circulation. The gas distributor then turns downward, causing the liquid level at the bottom of the tower to fluctuate violently under the impact of the high-speed gas, and even part of the liquid is entrained by the high-speed flowing gas to the mass transfer area, and the high-speed droplet group also entrains part of the light gas into the mass transfer area. At the bottom of the tower, the content of light components at the bottom of the tower increases, and it is difficult to ensure the quality of the product at the bottom of the tower, resulting in a decrease in the operating efficiency of the tower, and this structure is also not conducive to the smooth flow of the liquid entrained in the gas entering the tower into the bottom of the tower, so , the double tangential circulation gas distributor cannot reasonably solve the problem of liquid entrainment in the inlet gas at the bottom of the tower
