Abstract
The present invention relates to a spiral tower which belongs to gas liquid mass transfer equipment. The spiral tower with high separation efficiency is suitable for rectification and absorption. The height equivalent to one theoretical plate is less than 25mm, so that the height of the tower is greatly reduced.
Description
The invention belongs to gas-liquid mass transfer (contact) equipment.
At present, widely used valve tower in distillation process, its distance between plates is 300-500mm.The wire netting ripple packed tower that separative efficiency is higher, its height equivalent to one theoretical plate (HETP) is also up to about 100mm.If design needs the rectifying column of 100 column plate separation requirement, select valve tower for use, then tower height reaches about 50m, selects wire netting ripple packed tower for use, and tower height also needs about 10m.Therefore, develop high efficiency knockout tower,, be convenient to operate positive effect for reducing tower height.
Reduce the height equivalent to one theoretical plate (HETP) of tower effectively, reducing tower height significantly is purpose of the present invention.
The present invention adopts helical structure, has helicoid 1 and spiral space 2 in the tower, and helicoid 1 is made up of the dictyosome material.During operation, gas rises along spiral space 2, and liquid descends along helicoid 1, forms gas phase and liquid phase contact interface thus, carries out gas-liquid mass transfer.
The present invention carries out the column efficiency test with ethanol-water solution under the infinite reflux condition,, in scope, in certain pitch scope, reach in certain gas speed scope at certain tower, record the height equivalent to one theoretical plate (HETP) of the present invention below 25mm, promptly the separating effect of every meter tower height reaches about 40 theoretical plates.In unit height, its separative efficiency is about 20 times of valve tower.Be about 4 times of wire netting ripple packed tower.In addition, void tower pressure drop of the present invention is little, has operating flexibility preferably.
The present invention is applicable to rectifying, absorbs.
In conjunction with the description of the drawings, narrate enforcement of the present invention: 1-helicoid, 2-spiral space, 3-outer cylinder body, 4-inner barrel.The helicoid of being made up of the dictyosome material 1 is connected on the cylindrical shell 3,4 that two diameters of coaxial line do not wait, and constitutes the spiral tower with helicoid 1 and spiral space 2.
Claims (1)
1, a kind of rectifying column is characterized in that the helicoid of being made up of wind body material (1) is connected on the outer cylinder body (3) and inner barrel (4) that two diameters of coaxial line do not wait, and constitutes the spiral tower with helicoid (1) and spiral space (2).
