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

Embodiment 1

[0023] Such as figure 1 , 2 As shown, the new type of liquid trapping energy absorber is annular as a whole, and the upper layer of liquid trapping and energy absorbing plate 1 and the lower layer of liquid trapping and energy absorbing plate 2 are connected by the upper annular angle steel 3, the lower annular angle steel 5 and the annular rib 6 of the annular angle steel. One end of the supporting angle steel 4 is directly welded to the lower annular angle steel 5, the other end is welded to the tower wall, and the outer edge of the liquid-catching and energy-absorbing plate is directly welded to the tower wall.

[0024] The upper liquid-capturing and energy-absorbing plate 1 can be a rectangular plate or a trapezoidal plate, which is evenly distributed along the circumference. The upper liquid-capturing and energy-absorbing plate 1 forms a certain angle with the tower body, such as image 3 As shown, the effect of capturing liquid and energy can be better achieved.

[0025] Th...

Embodiment 2

[0028] The difference from Embodiment 1 is that the bottom end of the lower liquid-capturing and energy-absorbing plate 2 can be equipped with a horizontal folded plate when the gas flow rate is large to slow down the impact of high-speed gas on the kettle liquid, such as Figure 4 Shown.

Embodiment 3

[0030] The difference from Example 1 is that the upper liquid trapping and energy absorbing plate and the lower liquid trapping and energy absorbing plate are herringbone baffles, the angle of which is between 0 degrees and 180 degrees, such as Figure 5 As shown, they are uniformly distributed on the circumference, and the number can be converted from the flow area according to the gas flow rate, and the positions of the upper and lower chevron baffles are staggered.

[0031] The new liquid trapping energy absorber described in the present invention is applied to the bottom of a large tower in conjunction with a double tangential circulation gas distributor. At present, it has been practically applied in multiple towers. The application results show that:

[0032] The invention has the following characteristics:

[0033] 1. The new liquid trapping energy absorber can trap liquid droplets contained in the inlet air at the bottom of the tower;

[0034] 2. The new liquid trapping ene...

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 a rectification tower internal part, in particular to a liquid trapping energy absorber. technical background [0002] In the oil refining, petrochemical, fine chemical, food, medicine, and environmental protection sectors, towers are important unit equipment with a large volume and a wide range. The investment generally accounts for about 20% of the total investment, and some even as high as 50%. Towers 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 topic of general concern to scholars at home and abroad. [0003] With the development of tower equipment, the technology of tower internals has also been continuously developed and improved. Various new tower internals have emerged in an endless stream. In particular, the continuous improvement of gas distributors has promoted the optimizatio...
