Description

PFA self-distribution composite filler structure in filler tower

Technical Field

The utility model relates to an oil refining, chemical industry equipment internals technical field especially relates to a PFA is from compound filler structure of distribution in packed tower.

Background

In recent years, research and development and application of the filler are increased at home and abroad, and the filler with excellent performance is widely applied to a gas-liquid mass transfer device. The filler tower is filled with filler with a certain height in the tower body, a support grid or hump is arranged below the filler tower, and internal parts such as a grid gland and a liquid distributor are arranged above the filler tower.

The main factor influencing the efficiency of the packing tower in the packing tower is the poor distribution of liquid, and the bias flow of the liquid further influences the uniform distribution of gas and causes the bias flow of gas and liquid due to the wall approaching, channeling distribution and other reasons of the liquid in the packing layer. The deviation of the gas-liquid flow rate can cause that the local liquid-gas ratio is less than the minimum liquid-gas ratio, thereby failing to achieve the purpose of gas-liquid mass transfer separation. In order to avoid the influence of channeling and wall flow on the performance of the packing, a liquid collector and a redistributor are required to be arranged between every two sections of packing.

In order to eliminate the influence of channeling and wall flow effect, a liquid collector and a redistributor are arranged at intervals of 3-5m, the height of the space is 1.0-2.5m, and therefore, the spatial inefficiency is about 25-35%.

Therefore, we propose a PFA self-distribution composite filler structure in the filler tower to solve the above problems.
