Dialyzate flow improved dialyzer

The utility model discloses a dialysate flow improved dialyzer which comprises a dialyzer shell internally provided with membrane filaments, and the dialyzer shell communicates with a liquid outlet pipe. The dialyzer shell is provided with a liquid inlet cavity communicated with the interior of the dialyzer shell, the liquid inlet cavity is in a hollow horn shape, the large-diameter end of the liquid inlet cavity is connected with the dialyzer shell, and a liquid inlet pipe is installed at the small-diameter end of the liquid inlet cavity. A liquid separation part is mounted in the liquid inlet chamber, is in a hollow spherical shape and is provided with a liquid inlet port communicated with the liquid inlet pipe and a spraying flow channel located on the spherical surface; when dialysate is introduced into the dialyzer shell, the dialysate enters the liquid separation part from the liquid inlet pipe through the liquid inlet port and then enters the liquid inlet cavity from the liquid separation part through
