The invention provides an electric dehydrator inlet liquid-dispensing member. The electric dehydrator inlet liquid-dispensing member comprises a main flow guide tube, wherein the main flow guide tubeis communicated with a first-stage sub-flow guide tube; the first-stage sub-flow guide tube is communicated with a second-stage sub-flow guide tube through a plurality of branches of different tube diameters, and the second-stage sub-flow guide tube is communicated with distribution pipes through a plurality of branches; the distribution tubes are provided with a plurality of tube flow outlets with different values of tube spacing. The electric dehydrator inlet liquid-dispensing member can make liquid uniformly distributed in each tube flow outlet, reduce impact and disturbance of flowing liquid to the liquid in a separation device, and improve the electric dehydration efficiency.
