Description
The utility model relates to a kind of hump sieve plate regular tower filler, belongs to the plant equipment field of Chemical Engineering mass transfer separation process.
Packed tower is fields such as petroleum refining, chemical industry, medical environmental protection mass transfer apparatuses commonly used, is widely used in the unit operations such as rectifying, absorption, extraction.The performance of tower inner member and filler has decisive influence to the technical indicator of tower.Filler also is a kind of product that has a large capacity and a wide range, has great economic benefit, thereby many in the world countries have all carried out deep research to the structure and the performance of filler, have developed miscellaneous tower packing, but can be divided into granular filler and structured packing two big classes by its structure.Granular filler is a kind of granule with certain geometrical shape size, and structured packing then is to be made of a plurality of same geometry cell cubes, and is seated in the tower in whole mode of building.Because it is structured packing has simple in structure, excellent performance, convenient for installation and maintenance and be widely used.
The model and the kind of structured packing are a lot, and typical case's representative is that Switzerland's Suhl longevity China ink of (Sulger) company exploitation draws Parker (Mellapak) filler, and its structure as shown in Figure 1.It is by parallel to each other, the corrugated silk screen of arranged vertical or a kind of plate-like structured packing that the lath sheet is formed, the height of every dish filler is about the 40-200 millimeter, the inclination angle of ripple direction and tower axle is 30 ° or 45 °, adjacent two ripple directions are opposite, on corrugated plate, have aperture at a certain distance, the packing box diameter is littler several millimeters than tower diameter, closely fills tower section.This filler has in the rectification under vacuum of gas-liquid mass transferring operation that pressure drop is little, flux big, the efficient advantages of higher, but in the big operation of normal pressure or high pressure and liquid phase load, its pressure drop obviously increases, and flux significantly reduces.When using this filler, also liquid re-distributor must be installed, and the complex structure of liquid re-distributor, the space that occupies in tower is big, installs, overhauls all inconvenient.At these shortcomings of this filler, for improving the mass-transfer efficiency when the liquid phase load contacts with liquid-liquid greatly, must the excellent more new type high-efficient packing of exploitation performance.
The purpose of this utility model is a kind of hump sieve plate regular tower filler of design, improves the structure of structured packing in the prior art, so that the voidage of filler is big, pressure drop is low, and drop good dispersion degree, mass-transfer efficiency height.
The hump sieve plate regular tower filler of the utility model design is formed by the accumulation of 4-6 piece hump sieve plate rule, and adjacent two sieve plate position of opening stagger, and arrange at an angle of 90, and the height of filler is 60-300mm.Sieve plate is a hump shape, summit, peak valley and domatic on be arranged with the hole that the aperture is 8-20mm, pitch of holes is 16-40mm, the angle, peak is 60-90 °, peak valley is 10-30mm to the height of summit.
The utility model has not only increased the intensity of sieve plate greatly because horizontal sieve plate is washed into the hump type sieve plate, can adopt less than 1 millimeter steel plate and process, and sieve aperture is arranged in summit and peak valley wittingly.In the ordinary course of things, the tendency that the oriented trough of heavy phase (liquid phase) accumulates, light phase (gas phase) is then tended to pass from crest, the light of counter-current flow risen from the sieve aperture of summit in tower like this, the heavy phase then sieve aperture by peak valley descends, and the Kong Ze on domatic plays the effect of distribution certainly of regulating liquid level.Gas-liquid or liquid liquid two-phase with adverse current membrane type contact mass transfer, have so not only improved mass-transfer efficiency on every block of column plate, and have guaranteed that the flow resistance of full tower is little, pressure drop is low, flux is big.The flow mechanism of two-phase on every block of column plate as shown in Figure 4.I among the figure is represented heavy phase or continuous phase, and II is represented mutually light or decentralized photo, and two-phase is respectively with V
1, V
2Speed by sieve aperture, because the via hole speed V of decentralized photo
1Than its superficial linear velocity in a column V
3Much bigger, so by sieve aperture the time, disperse to be on good terms by the sieve aperture cutting, disperse very evenly, thereby the mass transfer surfaces that has increased in the unit volume is long-pending, improved the mass-transfer efficiency of full tower greatly.Because this filler good from distribution performance can promote the even distribution of gas-liquid and liquid liquid, need not to install again liquid distribution trough when therefore adopting this filler, thereby saved investment greatly and effectively utilized space in the tower, reduced the appearance and size of equipment.
Description of drawings:
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
Fig. 3 is the structural representation of monolithic sieve plate in the structured packing.
Fig. 4 is two-phase flow mechanism figure in the structured packing of hump sieve plate.
Below in conjunction with accompanying drawing, introduce in detail content of the present utility model.
Figure 1 shows that the structural representation of plate-like structured packing in the prior art. The hump that Fig. 2 designs for the utility model The sieve-plate regular tower packing structural representation, among Fig. 2 and Fig. 3, the 1st, the superiors' sieve plate of filler, the 2nd, summit, the 3rd, slope Hole on the face, the 4th, peak valley, the 5th, the hole on the summit.
As shown in Figure 2, every dish filler is piled up by 4-6 piece sieve plate 1 rule and is formed adjacent two sieve plates, position of opening mistake Open, and become 90 ° of arrangements, sieve plate from level to level consists of the filler of regular arrangement. The height of whole packing box is 60-300 Millimeter, the diameter of packing box is decided according to tower diameter, and is more smaller than tower diameter, so that it closely is seated in the tower. Every hump shape The structure of sieve plate has circular hole 5 at the summit 2 of hump as shown in Figure 3, and the diameter of circular hole is 8-20mm, between the hole Apart from being 16-40mm, have circular hole 3 on domatic, the diameter of circular hole is 8-20mm, pitch of holes 16-40mm, hump Peak valley 4 on also have circular hole, identical with circular hole 5, but not shown in FIG.. Adjacent two domatic angles are that the angle, peak is 60-90 °, summit 2 is 10-30mm to the height of peak valley 4. The hump shape sieve plate can be stamped to form by plate.
Introduce embodiment of the present utility model below:
Embodiment 1,
