Feeding distributor with anti-eddy flow baffle plate

Abstract

The invention provides a feeding distributor with anti-cyclone baffle plate, which comprises an inner muffle, a cover plate, a guide plate and an anti-cyclone baffle plate. Wherein, the guide plate is arranged between the tower wall and the inner muffle; the surface of guide plate that back to the inlet has a strengthen bar; the anti-cyclone baffle plate is arranged at the inner side of inner muffle whose side surface has a tie-bar; another end of tie-bar is fixed on the inner muffle; the cover plate is annular at the top of inner muffle whose one end is fixed on the tower wall and another end is fixed on the inner muffle; the baffle plate is used to resist the revolution of ascending airflow to reduce the entrainment on the liquid and distribute the ascending airflow. The invention has the advantages that: it can eliminate the airflow revolution caused by cyclone material feeding and eliminate the entrainment on the liquid drops, to avoid the non-uniformity of gas caused by the break of flow area and speed.

Description

technical field [0001] The invention relates to a gas-phase and gas-liquid two-phase feeding device for a tower, and more specifically relates to a single-tangential or double-tangential feed distributor with an anti-swirl flow baffle. Background technique [0002] The tower is a gas-liquid, liquid-liquid contact mass transfer equipment widely used in the petroleum and chemical industry. In the past ten years, with the large-scale development of packed towers and plate towers, the uniform distribution of liquid and gas in the tower is a key issue in the expansion of the tower, especially the initial distribution of the inlet fluid has a significant impact on the separation efficiency of the tower . At present, most of the tower feed distributors used in the industry are mostly straight pipes with holes or other different feed flow guide devices to achieve uniform distribution of the flow in the tower. The rate of flow out of the openings is d...

AI Technical Summary

Problems solved by technology

At present, most of the tower feed distributors used in the industry are mostly straight pipes with holes or other different feed flow guide devices to achieve uniform distribution of the flow in the tower. The rate of outflow from the openings is different, so it is difficult for this kind of distributor to achieve the purpose of evenly distributing the material

However, the deflectors of other feed distributors have disadvantages such as large pressure drop of gas flow and uneven distribution of gas vortex above the distributor.
