The specific implementation mode is as follows:

referring to fig. 1-7, a rectifying tower distributor comprises a liquid inlet pipe 1, a buffer cylinder 2 and a liquid separating disc 3; the liquid separating disc 3 comprises a groove disc 31 and a plurality of ring groove discs 32 of ring sleeves, wherein the ring groove discs 32 of the inner ring are connected with the groove disc 31 through ribs or ribbed plates which are uniformly distributed on the circumference, the ring groove discs 32 of the ring sleeves are connected through the ribs or ribbed plates which are uniformly distributed on the circumference, overflow holes 34 which are uniformly distributed on the circumference are arranged at the upper parts of the groove disc 31 and the ring groove discs 32, liquid separating pipes 33 which are uniformly distributed on the circumference are welded in the groove disc 31 and the ring groove discs 32, the top ends of the liquid separating pipes 33 are lower than the overflow holes 34, the bottom ends of the liquid separating pipes extend to the outside of the disc bottom, and the bottom ends of the; the buffer cylinder 2 comprises a cylinder body 21 and a plurality of liquid distribution pipes 22 which are uniformly distributed on the circumference, and the liquid distribution pipes 22 are positioned on the upper part of the cylinder body 21; the bottom end of the liquid inlet pipe 1 extends to the lower part of the buffer cylinder 2, the buffer cylinder 2 is arranged above the liquid separating disc 3 and is connected with the groove disc 31 through support rods which are uniformly distributed on the circumference, and a liquid distribution pipe 22 is respectively arranged above the groove disc 31 and each annular groove disc 32; the liquid outlet of the liquid distribution pipe 22 is higher than the top ends of the groove disc 31 and the ring groove disc 32; the end part of the liquid inlet pipe 1 is provided with a connecting flange or connecting threads; the groove disc 31 is flush with the top ends of the liquid distributing pipes 33 in the plurality of annular groove discs 32; the height of the groove disc 31 is consistent with that of the overflow holes 34 at the upper parts of the plurality of ring groove discs 32; the liquid inlet pipe 1, the buffer cylinder 2 and the liquid separating disc 3 are made of plastic or stainless steel.

The initial liquid inlet has large and unstable flow rate, and liquid enters the liquid inlet pipe and then flows into the buffer cylinder for buffering instead of being directly separated by the liquid separating disc. The liquid flows into the bottom of the buffer cylinder firstly, the buffer cylinder is filled with the liquid, and the liquid after the flow stabilization in the buffer cylinder overflows into each annular groove disc for liquid separation through the liquid distribution pipes with the same height. The liquid entering the ring groove disc flows downwards after being separated by the liquid separating pipes with the same height in an overflow mode. Liquid distributing pipes of all the annular groove discs on the liquid distributing disc are uniformly distributed on the whole in a circumferential mode, so that liquid can be uniformly distributed. And the bottom of the liquid distribution pipe is provided with the circumferential wave teeth, so that the liquid distributed in the downflow mode is more uniformly distributed, and the phenomenon of small pipe radial flow wall can not be caused.
