Downcomer Buffer Device for Multiple Downcomer Trays

Abstract

The invention relates to a multi-downcomer tray, in particular to a downcomer buffer device for a multi-downcomer tray. It includes a first side baffle, a second side baffle, an intermediate connecting plate and an anti-shock plate. The first side baffle and the second side baffle are welded together through four intermediate connecting plates arranged parallel to each other. The two intermediate connecting plates are respectively located at the four corners of the first side baffle and the second side baffle; multiple anti-shock plates are arranged between the first side baffle and the second side baffle, and a plurality of anti-shock plates are arranged between the first side baffle and the second side baffle. The punching plates are distributed sequentially from the first side baffle to the second side baffle, and the two ends of the anti-shock plates are respectively welded to the two intermediate connecting plates; The direction of inclination is opposite; the anti-scouring plate is provided with a plurality of downholes. The invention can reduce the impact of the liquid in the downcomer on the bubbling structure on the liquid receiving plate through the arrangement of the anti-scouring plate and the downcomer hole, and the arrangement of the downcomer buffer device does not affect the liquid separation and treatment efficiency of the entire column.

Description

technical field [0001] The invention relates to a multi-downcomer tray, in particular to a downcomer buffer device for a multi-downcomer tray. Background technique [0002] In oil refining, chemical industry, petrochemical industry and light industry, a large number of towers are used to separate mixtures to high-purity products or to remove harmful substances in gas and water to protect the environment. With the rapid development of the petroleum and chemical industry, energy is becoming increasingly scarce, equipment is larger and capacity is continuously expanded to increase production, improving the processing capacity and effect of towers, and reducing energy consumption have become the mainstream of tower development today. [0003] Multiple downcomer trays have been used in chemical towers. The multi-downcomer tray hangs the downcomer in the gas phase space. The bottom of the downcomer is provided with a bottom plate, and a bottom hole is opened on the bottom plate f...

Problems solved by technology

[0005] However, in the actual use process, in order to achieve the purpose of avoiding the bubbling area of ​​the liquid receiving position, the setting area of ​​the downcomer is limited, and the setting number of the bubbling area of ​​the receiving liquid is also limited, which affects the operation of the entire column. Liquid separation treatment efficiency
