Detailed Description

The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in FIG. 1, a liquid redistributor with a supporting function is installed in a packed tower and comprises a liquid collecting component 100 and a liquid redistributing component 200.

The liquid collecting assembly 100 comprises at least two layers of collecting trays, the upper layer collecting tray 110 and the lower layer collecting tray 120 are connected through at least two sets of flow distribution supporting pieces 130, filtering holes 111 are formed in the upper layer collecting tray 110 and the lower layer collecting tray 120, and axial drainage grooves 112 are formed in the side faces of the filtering holes 111. Each set of branch supporting members 130 comprises two branch supporting rods 131, one ends of the two branch supporting rods 131 are connected with each other at the bottom of the upper layer collecting tray 110 to form an angle of 60-90 degrees, and the included angle between each branch supporting rod 131 and the upper layer collecting tray 110 is 45-60 degrees. As shown in fig. 2, the shunt support rod 131 is sleeved with the shunt sleeve 132, and the side surface of the shunt sleeve 132 has a spiral line or a comb-tooth line.

The liquid redistribution assembly 200 comprises a liquid collecting tray 210, the liquid collecting tray 210 is connected with the lower collecting tray 120 through a plurality of supporting columns 220, two ends of each supporting column 220 respectively penetrate through the upper collecting tray 120 and the liquid collecting tray 210, and overflow through holes are formed in the side faces of the supporting columns 220. A liquid redistribution structure 230 is arranged between two adjacent support columns 220, the liquid redistribution structure 230 comprises a plurality of first downcomers 231 and a plurality of second downcomers 232, the upper ends of the first downcomers 231 extend into the filtering holes of the lower-layer collecting tray 120, and the lower ends of the first downcomers 232 penetrate through the collecting tray 210; the pipe wall of the second downcomer 232 is connected with the column wall of the support column 220, the upper end of the second downcomer 232 is lower than the bottom surface of the lower collection tray 120 by 5-8cm, and the lower end of the second downcomer 232 penetrates through the collection tray 210. The bottom surfaces of the first downcomer 231 and the second downcomer 232 are flush.

The working principle of the liquid redistributor is as follows: the liquid redistributor is installed in the packed tower together with the packing layer, the liquid distributor is installed below the packing layer, and the upper collection tray 110 is used as a packing support plate to support the packing. Because the shunting support rods 131 are arranged between the upper-layer collecting tray 110 and the lower-layer collecting tray 120, and a stable triangular structure is formed between every two shunting support rods 131 and the upper-layer collecting tray 110 or the lower-layer collecting tray 120, stress is dispersed, and the supporting effect is good.

When liquid flows out from the gaps of the filler layer, the liquid is firstly redistributed for the first time through the filtering holes 111 in the upper collecting tray 110 and the action of the drainage grooves 112, when the liquid flows out from the filtering holes 111 and falls on the lower collecting tray 120, part of the liquid falls on the flow-dividing supporting rods 131, and is redistributed for the second time through the separating sleeves 132 with special shapes. The liquid falling onto the lower collection tray 120 is third redistributed by the action of its perforations 111 and drainage slots 112. The liquid filtered from the lower collection tray 120, some of which flows directly into the first downcomer 231; some of the liquid falls onto the liquid collecting tray 210, and flows into the top end of the second downcomer 232 after being accumulated to a certain height; some overflow through holes passing through the support column 220 flow from the outside of the support column 220 to the inside of the liquid redistribution structure 230, partially flow directly into the second downcomer 232, partially fall onto the drip pan 210, and accumulate to a certain height to flow from the top end of the second downcomer 232. Finally, the liquid uniformly flows out from the bottom ends of the first downcomer 231 and the second downcomer 232 to obtain the fourth redistribution.

The liquid redistributor has the advantages that the liquid redistributor improves the liquid redistributing effect and simultaneously has the supporting function of the packing layer, and the cost is saved.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
