Abstract

The present invention discloses an isoprobability type self-distributed filler tower. Fillers in the filler tower are divided into a plurality of longitudinal filler units by separation plates; the values of the cross section shapes of the fill units in the middle part the tower are the same; periphery filler units are engaged with circular arc surfaces of the internal walls of the tower, and the fillers are provided with hump support distributors at intervals of certain height. The filler tower can obstruct the radial flow of fluid, eliminate the boundary effect and weaken the amplification effect of the filler tower. Sections are not needed among the filler sections in the tower, and accordingly, the tower internals have compact structure, and the tower body space is saved.

Description

Isoprobability-type self-distributed filler tower
Technical field
The present invention relates to the packed tower that a kind of petrochemical industry project is used.
Background technology
Since the self filler tower came out, because its high column efficiency is developed rapidly, but " enlarge-effect " of packed tower perplexing people always.Such as, the number of theoretical plate of every meter filler (NTSM) is up to 50 in the minor diameter tower, and the NTSM of industrial tower has only 1--8, and the main cause that NTSM reduces significantly along with the tower diameter increase is mobile the causing of uneven distribution, " wall stream effect " and radial fluid of fluid.Simultaneously, experiment shows that also large-area uneven distribution is quite big to the separative efficiency influence of tower, and the uneven distribution of inner fluid is not too obvious to the separative efficiency influence of tower among a small circle.In order to address this problem, people design a lot of ways, heavy water knockout tower such as nineteen fifty University of Basel's physics research institute chief W. storehouse grace invention, be formed in parallel by a plurality of tubule type towers, after, people are by research various ways distributor, attempt to make as much as possible fluid to obtain uniform initial distribution, but can not get thorough solution for " the wall stream effect " around inhomogeneous mobile and the Radial Flow and the packing section of packing section inner fluid, the structure that can only depend on filler self reduces bad mobile degree.So just, divide a secondary segment again, leave certain space, redistributor is set, the interior gas-liquid phase logistics of tower is once redistributed in this space a natural packing section every 3--8 rice; To realize this process by location grid and supportive grid being set up and down respectively simultaneously in adjacent packing section.Waste the tower body space, increased manufacturing cost (as Fig. 1).Until recently, some domestic filler production firm is by dosing flow apron (as Fig. 2) at the packed tower wall, to reduce " wall stream effect ", by double-deck novel distributor is set in packing section, to save the tower body space, these measures have been played certain effect to improving NTSM, but all can not tackle the problem at its root.
Summary of the invention
The objective of the invention is: a kind of Isoprobability-type self-distributed filler tower is provided, and this packed tower can cut off the Radial Flow of fluid, eliminates wall effect, weaken the enlarge-effect of packed tower, and without segmentation, make the tower internals compact conformation between the inner-tower filling material section, save the tower body space.
Technical scheme of the present invention is: the filler in a kind of Isoprobability-type self-distributed filler tower, this packed tower is separated into several filler units longitudinally by dividing plate; The filler unit cross sectional shape size at middle part filler unit and inner wall of tower arc surface identical, the edge coincide in the tower.
The further technical scheme of the present invention is: the filler in a kind of Isoprobability-type self-distributed filler tower, this packed tower is separated into several filler units longitudinally by dividing plate; The filler unit cross sectional shape size at middle part filler unit and inner wall of tower arc surface identical, the edge coincide in the tower; Described filler unit is provided with several layers on short transverse, the lower edge of last layer dividing plate is divided into some fins, and per two adjacent fins are to the both sides formation prong that staggers, and the upper edge of following one deck dividing plate just is inserted in the prong.
The more detailed technical scheme of the present invention is: the filler in a kind of Isoprobability-type self-distributed filler tower, this packed tower is separated into several filler units longitudinally by dividing plate; The filler unit cross sectional shape size at middle part filler unit and inner wall of tower arc surface identical, the edge coincide in the tower; Described filler unit is provided with several layers on short transverse, the lower edge of last layer dividing plate is divided into some fins, and every two adjacent fins are to the both sides formation prong that staggers, and the upper edge of following one deck dividing plate just is inserted in the prong; Described filler is provided with hump every certain altitude and supports distributor; Described hump supports distributor and comprises a gripper shoe, the hump bar that it is isosceles triangle that the last plane parallel of gripper shoe is arranged with some the cross sections that are converted into by sheet material, the both sides on hump bar top are provided with the shutter that opening makes progress, gripper shoe between the two adjacent hump bars is provided with the distribution hole, the hump bar disconnects in the centre position, forms groove.
For the random packing tower, described dividing plate is the winding sheet that knuckle equates, several winding sheet splicings are divided into a plurality of cylinders with filler, and this cylinder is filler unit.
For regular packed tower, described dividing plate is to be wrapped in filler unit corrugated plating all around, and the ripple direction of any two contacted corrugated platings is opposite.
Advantage of the present invention is:
1. the present invention is applicable to random packing tower and regular packed tower.
2. the present invention is divided into a large diameter packed tower mass transfer unit tower composition that is equivalent to a plurality of little equivalent diameters.
3. the present invention can cut off the Radial Flow of fluid, eliminates wall effect, weakens " enlarge-effect " of packed tower.
4. the present invention has adopted hump to support distributor, and without segmentation, the tower internals more compact structure has been saved the tower body space between the packing section, and can realize between a natural packing section from distributing.
5. the present invention still has effect of mass transmitting between each mass transfer unit tower of regular packed tower.
6. the present invention has increased substantially the mass-transfer efficiency of big-and-middle-sized packed tower.
