Chinese patent 200420047531.8 discloses a kind of honeycomb tougue regular tower filling, as depicted in figs. 1 and 2, by polylith grille strip 1 '-4 ' form filler body, and tongue piece 5 ' is had on every block grille strip, angle α between tongue piece 6 ' and grille strip is between 30 ° to 70 °, tongue piece 5 ' can be many rows, and the edge that grille strip contacts with tower wall is processed into the camber line identical with tower wall, when making it be stacked in tower can with tower wall no-float.
In this patent, although tongue piece 5 ' effectively can promote the mass exchange of fluid between filler, and the fragmentation of drop can be promoted, be conducive to improving mass-transfer efficiency, and percent opening be higher, more be conducive to improving mass-transfer efficiency.But meanwhile, because tongue piece 5 ' is horizontal direction or close to horizontal direction in tower, when fluid flow to tongue piece 5 ' place, part is blocked, and can only flow to the periphery of tongue piece 5 ', do perpendicular flow down or up again, also namely the structure of tongue piece 5 ' creates larger inhibition to the two-phase flowed up and down in tower, and percent opening is higher, and this obstruction is larger, and then reduce flux, that is, this kind of filler, while effectively improving mass-transfer efficiency, sacrifices flux.
Utility model content
Technical problem to be solved in the utility model is to provide has higher flux, also has the guide grid structured packing of higher mass-transfer efficiency and very strong anti-coking and blocking ability simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Guide grid structured packing, by arranging grille strip group I more and coming vertical direction more, to be symmetrical in the grille strip group II of grille strip group I assembled in this structured packing, and be filled in packed tower in the mode of whole block, often arrange grille strip group I or grille strip group II to be made up of the grille strip that polylith is arranged in parallel in same plane, every block grille strip upper punch is pressed with pilot hole, and pilot hole opening direction on the grille strip be parallel to each other is consistent, the pilot hole opening direction on adjacent grille strip is symmetrical in vertical direction.
Further, the pilot hole on the grille strip be parallel to each other is corresponding or be staggered.
Further, the pilot hole on every block grille strip is at least two rows.
Further, the perforate face of pilot hole is circular, square or trapezoidal.
Further, the percent opening of the pilot hole on every block grille strip is 5-40%.
The utility model has the advantages that: compared with existing structured packing, structured packing of the present utility model is when mass-transfer efficiency is suitable, processing flux improves more than 50%, theoretical stage equivalent altitude reaches more than 0.7m, there is very strong anti-coking and blocking ability, and processing and fabricating is convenient, mechanical strength is high, and installation and maintenance are simple.

Detailed description of the invention:
As shown in Figures 3 to 6, guide grid structured packing, by arranging grille strip group I1 more and coming vertical direction more, to be symmetrical in the grille strip group II2 of grille strip group I1 assembled in this structured packing, and be filled in packed tower in the mode of whole block, often arrange grille strip group I1 or grille strip group II2 to be made up of the grille strip 3 that polylith is arranged in parallel in same plane, every block grille strip 3 upper punch is pressed with the pilot hole 4 of a row or more, and pilot hole 4 opening direction on the grille strip 3 be parallel to each other is consistent, pilot hole 4 opening direction on adjacent grille strip 3 is symmetrical in vertical direction, pilot hole 4 on the grille strip 3 be parallel to each other is staggered, also can be corresponding setting, the percent opening of the pilot hole 4 on every block grille strip 3 is 5-40%.
As shown in Figure 7, the perforate face of pilot hole 4 is can for circular, also can be square or trapezoidal, and the perforate face of pilot hole 4 is separated with grille strip 3, its lap is still connected with grille strip 3, little on the perpendicular flow impact of fluid, therefore, the pilot hole 4 of above-mentioned structured packing both can cut fluid decentralized photo, improve the effective actual internal area of fluid in tower, simultaneously do not hinder again fluid flowing in the vertical direction, even if also do not affect flux when percent opening is higher, and percent opening more high being more conducive to improve mass-transfer efficiency.
Adopt above-mentioned structured packing, and percent opening is set to 21%, between the grille strip 3 that is parallel to each other distance h is set to 20mm, voidage is set to 94.8%, be respectively used to coal oil-water system, 30%TBP(kerosene)-acetic acid-water system and heavy-oxygen-enriched water-air system time test result as follows:
As shown in Figure 8, this structured packing carries out extraction water mechanical test at coal oil-water system, and its liquid flooding flux is relatively large, and when velocity ratio is 1:1, liquid flooding flux is 109m
3/ m
2h; When velocity ratio reaches 1:5, liquid flooding flux reaches 150 m
3/ m
2h;
As shown in Figure 9 and Figure 10, this structured packing is at 30%TBP(kerosene)-acetic acid-water system carries out extraction ability test, and when velocity ratio is 1:1, liquid flooding flux is 112 m
3/ m
2h; When velocity ratio reaches 1:5, liquid flooding flux reaches 146 m
3/ m
2h; Theoretical stage equivalent altitude increases with velocity ratio and reduces, the minimum 0.7m that reaches, and has higher mass-transfer efficiency;
As shown in figure 11, this structured packing carries out oxygen desorb test in heavy-oxygen-enriched water-air system, take water as continuous phase, air is decentralized photo, concurrent flow in packed tower, height of transfer unit, with the existing decline necessarily of increase of velocity ratio, then rises, totally remain on 0.2-0.25m, mass-transfer efficiency is higher.Owing to there is no liquid flooding problem, therefore there is not the graph of a relation that liquid flooding flux changes with velocity ratio.This structured packing can be used for gas-liquid mass transfer, as systems such as the oxidizing towers in Hydrogen Peroxide Production.
