Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-5, an evaporator distributor, including a pipe body 1, a first porous plate 2 is arranged inside the pipe body 1, and a second porous plate 3 is arranged above the first porous plate 2 inside the pipe body 1, a third porous plate 4 is arranged above the second porous plate 3 inside the pipe body 1, a plurality of first-level distribution holes 5 have been evenly opened on the first porous plate 2, a plurality of second-level distribution holes 6 have been opened on the second porous plate 3, and each first-level distribution hole 5 corresponds to three second-level distribution holes 6, a plurality of third-level distribution holes 7 have been opened on the third porous plate 4, and the third-level distribution holes 7 are distributed at the gap of the second-level distribution holes 6, the diameter of the first-level distribution holes 5 is greater than the second-level distribution holes 6, and the diameter of the second-level distribution holes 6 is greater than the third-level distribution holes 7.
The utility model discloses a set up first perforated plate 2 together, second perforated plate 3 and third perforated plate 4, and evenly set up a plurality of one-level distribution holes 5 on first perforated plate 2, through set up a plurality of second grade distribution holes 6 on second perforated plate 3, and every 5 bottoms in one-level distribution hole correspond three second grade distribution hole 6, through set up a plurality of tertiary distribution holes 7 on third perforated plate 4, and tertiary distribution hole 7 corresponds the space department of second grade distribution hole 6, establish to one-level distribution hole 5 through the size with distribution hole and be greater than second grade distribution hole 6 and be greater than tertiary distribution hole 7, the heat exchange tube equipartition that can make the feed liquid that gets into distributes at falling film evaporator's inner wall, and the film form flows down, reach vapour-liquid separation effect, reduce evaporimeter series connection quantity, and reach same separation effect.
