Y-shaped baffle with opening and in-tower arranging mode thereof

Abstract

The present invention relates to a Y-shaped baffle which has an opening and is used for the easy-obstructed large-scale tower with high heat exchange capacity of steam-liquid. According to the Y-shaped baffle with the opening, two liquid folding plates (1) are connected with an inclined beam (2) through the form of welding or movable connection for forming the Y-shaped baffle. Two end of baffle are installed with a support (3) and a tower wall welded part (4). The opening rate of liquid folding baffle is 1-50%. The in-tower arranging mode is that two supports and tower wall welded parts at twoends of baffle are welded on the inner wall of tower. The horizontal edge distance L2 between adjacent baffles of the Y-shaped baffle at the same layer is less than the width L1 of the liquid foldingplate. The invention provides a technique with low pressure reduction, efficient heat transmission and obstruction prevention, and a device thereof. When the technique is applied in the easy-obstructed large-scale tower with high heat exchange capacity, the problems of high pressure reduction, easy obstruction and low heat transmission efficiency of empty tower are overcome. The efficiency heat exchange and long-period operation of tower device are realized.

Description

field of invention [0001] The invention mainly relates to tower internals, in particular to a herringbone baffle plate with openings for a large-scale tower that is easy to block and has high vapor-liquid high heat exchange heat and its arrangement in the tower. Background technique [0002] In the departments of oil refining, petrochemical, fine chemical, food, medicine and environmental protection, towers are important unit equipment with a large volume and wide range, and their investment generally accounts for about 20% of the total investment, and some even as high as 50%. Columns 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 issue that scholars at home and abroad have generally paid attention to. [0003] In recent years, with the continuous development of tower technology, especially the increasing requirements for long-term operation of large...

Problems solved by technology

[0004] The object of the present invention is to provide a low-pressure drop, high-efficiency heat transfer, and anti-clogging technology and equipment. This technology is applied to large-scale rectification towers with high gas-liquid heat transfer and easy-to-block materials, and overcomes the high pressure drop of traditional internal parts. The problems of easy blockage and low heat transfer efficiency of the empty tower have realized efficient heat transfer and long-term operation of the tower equipment
