A high throughput tray tower

Abstract

The invention discloses a high-flux plate-type tower. A tray plate is inclined downwards along the liquid flowing direction. A gas guide plate is fixed below the tray plate, and is obliquely arranged, and the inclination direction of the gas guide plate is opposite to that of the tray plate. A down-flow plate of a down-flow pipe is obliquely arranged, and is arranged below the gas guide plate, the upper end of the down-flow plate is fixedly connected with the gas guide plate, and a gap is formed between the lower end of the down-flow plate and a lower liquid receiving disc. The structure of the high-flux plate-type tower can be used for a single-overflow, double-overflow or multi-overflow plate-type tower. By inclining the tray plate, the liquid runner is lengthened, and the area of a bubbling region is increased; by changing the liquid flowing state on the tray plate, the gradient of a liquid surface and the thickness of a liquid layer can be reduced, the pressure drop is reduced, and the transferring efficiency and the machining capacity can be improved. By installing the gas guide plate, the flowing direction of the airflow ascending from the lower tray can be changed, the length of the runner is increased, the mist foam can be reduced, and the operation upper limit of the tray plate can be improved. By adopting the oblique down-flow plate, the volume of the down-flow pipe is increased.

Description

technical field [0001] The invention relates to a plate type fractionation or rectification tower, in particular, relates to a plate type tower internal part structure, which is mainly used in technical fields such as petroleum and petrochemical industry, environmental protection, food and medicine. Background technique [0002] As an important mass transfer and separation equipment in petroleum, petrochemical, pharmaceutical and other fields, plate fractionation / rectification tower is widely used. Tray column internals mainly include tray plates, downcomers, feed distributors or distribution pipes, oil collection tanks, gas distributors, liquid extraction and other structures. Tray plates and downcomers are the main internal components of the plate column, and their type and structure determine the processing capacity and product separation accuracy of the plate column. Over the years, the development of mass transfer and separation technology has driven the progress of va...

Problems solved by technology

However, although the special structure of the suspended downcomer increases the area of ​​the bubbling area of ​​the tray, it affects the operating flexibility and separation efficiency; The processing capacity of the liquid load, but the short flow of the liquid on the tray plate also affects the mass transfer efficiency

Therefore, although the MD plate column technology can effectively improve the processing capacity of the high liquid load fractionation column, the mass transfer efficiency will be slightly reduced, and the operating flexibility will be greatly affected
