The utility model relates to a novel emulsion uniform distributor suitable for crude oil emulsion electrostatic dehydrator, include by last liquid stream energy dissipation speed reduction chamber and the cloth sap cavity that sets gradually under to in electrostatic coalescence part outlet pipe below, liquid stream energy dissipation speed reduction chamber is the diameter by last under to crescent expander column structure, and its upper end connects electrostatic coalescence part outlet pipe lower extreme mouth of pipe department, the cloth sap cavity is the cylindric structure of upper end open -ended, and its open end is connected the lower extreme in liquid stream energy dissipation speed reduction chamber, a plurality of cloth liquid holes have been seted up respectively to cloth sap cavity lateral wall and bottom. The advantage: simple structure, reasonable in design, the dismouting is washd conveniently, and the efficiency effect is better, and cloth liquid homogeneity is better for the oil hydrosol can be fine by the play of this emulsion uniform distributor equipartition, can with the fine even combination of electric field of sedimentation part, improve the separation effect and the efficiency of whole oil hydrosol.
