as shown in fig. 1-3, the staggered inner-extending tongue blade ring intalox saddle packing comprises an upper saddle wall 1, an upper tongue blade 2, a standard transverse tongue blade 3, a lower tongue blade 4, a lower saddle wall 5, a middle arc-shaped transition section and a support column 6, wherein the upper saddle wall 1, the lower saddle wall 5 and the middle arc-shaped transition section are of a saddle-shaped integrated structure, the three upper tongue blades 2 are connected with the upper saddle wall 1, the three upper tongue blades 2 are uniformly distributed along the arc section of the upper saddle wall 1, the three lower tongue blades 4 are connected with the lower saddle wall 5, the three lower tongue blades 4 are uniformly distributed along the arc section of the lower saddle wall 5, the two ends of the standard transverse tongue blades 3 are connected with the middle arc-shaped transition section, and the support column 6 penetrates through the upper tongue blades 2 and the lower tongue blades 4 along the axis; the middle arc transition section is provided with an upper layer window hole 8 and a lower layer window hole 10 along the arc direction, and a transverse runner groove 7 is arranged on the barrier between the upper layer window hole 8 and the lower layer window hole 10. When the load is arranged on the structure, the upper and lower layers of tongues and the standard transverse tongues 3 can improve the distribution of gas and liquid, and the wall flow trend is changed. The standard transverse tongue blade 3 can well concentrate and redistribute gas and liquid to prevent the phenomenon of stress concentration, the transverse diversion trench 7 of the middle arc-shaped transition section further increases the porosity of the filler, has larger mass transfer contact area, increases the separation flow, improves the separation efficiency and realizes the self-fluid regulation of the filler.
The two standard transverse tongues 3 are arranged at intervals; an upper short arc piece 11 is formed by an inward extending branch at one end of the lower part of the upper standard transverse tongue blade 3, an upper long arc piece 12 is formed by an inward extending branch at the other end of the lower part of the upper standard transverse tongue blade 3, the upper short arc piece 11 extends to be fixedly connected with the supporting column 6, an inward bend of the upper long arc piece 12 is fixed with the supporting column 6 in a tangent way, a lower long arc piece 14 is formed by an inward extending branch at one end of the upper part of the lower standard transverse tongue blade 3, a lower short arc piece 13 is formed by an inward extending branch at the other end of the upper part of the lower standard transverse tongue blade 3, the lower short arc piece 13 extends to be fixedly connected with the supporting column 6, an inward bend of the lower long arc piece 14 is fixed with the supporting column 6 in a tangent way, the upper short arc piece 11 and the lower short arc piece 13 are fixed on the supporting column 6 in an up-down staggered way, and the upper long arc piece 12, the lower long arc pieces 14 are staggered up and down to gather the supporting column 6 in the inner wall of the inner standard transverse tongue leaf to form a short tongue leaf, and the short tongue leaf points to the supporting column 6. A middle window hole 9 is formed between the two standard transverse tongue blades 3, and the upper layer window hole 8, the middle window hole 9 and the lower layer window hole 10 are arranged in a staggered mode along the vertical direction.
The invention adopts a double-layer tongue leaf layer structure, pall ring packing and intalox saddle packing are combined, the upper and lower layers are tongue leaf layers with opposite rotation directions, and tongue leaves of each layer are uniformly distributed on the saddle wall and are intersected with the support column 6. When the load is arranged in the structure, the gas-liquid collecting and redistributing function can be realized, and the wall flow trend is changed.
The diameter of the upper saddle wall 1 is smaller than that of the lower saddle wall 5 in the embodiment, the bridging phenomenon can be effectively prevented due to the fact that the outer diameters of the upper saddle wall and the lower saddle wall are different, the middle arc transition section ensures the void ratio of the filler, and the gas-liquid distribution performance can be improved.
The gas phase and the liquid phase are uniformly distributed in the filler, the working efficiency of the filler tower is high, and if the gas phase and the liquid phase are uniformly distributed all the time, the high mass transfer efficiency of the filler can be ensured. The invention realizes the concentration and redistribution of gas and liquid by arranging two layers of tongue blades with opposite rotation directions and staggered distribution up and down; the arc transition section is arranged to reduce stress concentration, improve a stress structure and prolong the service cycle.
Numerous practices have shown that the packing plays a crucial role in the normal operation of the packed column. The packed tower needs to be produced with high efficiency all the time, and not only needs to reduce bridging and wall flow in the working production of the packing, but also needs to change various loads to solve the problem of superposition in the random stacking process, thereby prolonging the service life. Therefore, the invention effectively makes up for a plurality of defects existing in the current packing, ensures the mass transfer process of the packing to be more stable from the source and has better working effect.
The analysis of two fluids flowing across the surface of the packing of the unit cell was performed using the software CFX as follows:
two-phase longitudinal simulation analysis:
the bulk flow rate of the fluid flowing over the standard packing surface in a two-phase longitudinal flow field is 5.443e-001m/s, and the bulk flow rate of the fluid flowing over the packing surface of the present invention is 2.352e +000 m/s. The maximum pressure of the standard packing is 5.139e +002Pa, and the fluid pressure of the surface of the packing of the invention is 3.125e +002 Pa. The flow rate situation is increased over the standard configuration due to the influence of the collection and redistribution effect of the blades of the structure. The maximum pressure condition is reduced slightly from the standard configuration because the configuration reduces the outer diameter of the upper and lower saddle walls compared to the standard packing configuration, thereby reducing the pressure of longitudinal fluid flow across the surface. Compared with the standard packing, the novel packing has the advantages that the upper and lower layers of tongues added by the novel packing have the functions of collecting and redistributing fluid, the influence of wall flow is reduced, and the liquid spreading capacity is greatly improved compared with that of the standard intalox saddle packing.
Two-phase transverse simulation analysis:
the bulk fluid flow rate through a standard packing surface was 2.658e +000m/s for a two-phase transverse flow field, and 1.656e +000m/s for the packing surface of the present invention. The maximum pressure of the standard packing is 1.788e +003Pa, and the fluid pressure of the surface of the packing of the invention is 9.588e +002 Pa. The flow rate is somewhat reduced from the standard configuration due to the structural support that enhances the column's barrier effect on fluid flow under two-phase flow. The maximum pressure conditions are slightly reduced from the standard configuration because of the reduced outer diameter of the saddle walls and the open cross-flow channel effect. Compared with the standard filler, the novel filler has the advantages that the supporting reinforcing column added in the novel filler and the standard transverse tongue blade connected with the supporting reinforcing column generate the collection and redistribution effects on fluid under the flow field of two-phase fluid, and the transverse runner groove formed in the novel filler enables the flow line of the fluid runner to be smoother, so that the fluid resistance influence caused by the supporting column is alleviated to a certain extent.
