Vortex type liquid disperser

The invention discloses a vortex type liquid disperser which is provided with a cylindrical inner cavity main body; a main flow inlet is formed in the axial front end of the inner cavity main body, an outlet is formed in the axial rear end of the inner cavity main body, and the diameter of the section of the main flow inlet is smaller than that of the section of the inner cavity main body; and a branch flow inlet is formed in the pipe wall of the disperser and is positioned at one end, close to the main flow inlet, of the inner cavity main body. Water enters from the main flow inlet and chemical liquid is added from the branch flow inlet, so that vortexes are generated at the joints of the main flow inlet, the branch flow inlet and the inner cavity main body, and the chemical liquid is added to a vortex area from the tangential direction of the bottom surface of the vortex area; and a small part of water is shunted from the main water flow path by utilizing an external bypass pipeline, and the water and the c
