Abstract

The present invention relates to the technical field of organic matter separation and purification. Disclosed are a mixer and an acid-hydrocarbon separation system and method. The mixer comprises: a housing, wherein a mixing cavity is provided inside the housing, a first liquid inlet through which a raw material liquid enters the mixing cavity is provided on the head end of the housing, and a liquid mixture outlet through which a liquid mixture flows out of the mixing cavity is provided on the tail end of the housing; and a conveying pipe, the conveying pipe running through the mixing cavity via the head end of the housing and extending to the tail end of the housing, wherein a first port of the conveying pipe located at the head end extends out of the housing and forms a second liquid inlet, a second port of the conveying pipe located at the tail end is closed, the part of the conveying pipe located in the mixing cavity forms a spraying section, a plurality of spraying holes distributed at intervals and configured to spray to the mixing cavity a dispersed phase inputted through the second liquid inlet are provided in the pipe wall of the spraying section, and a first helical blade and a second helical blade which are distributed at an interval in the axial direction of the spraying section are provided on the periphery of the spraying section, with the helical direction of the first helical blade being opposite to the helical direction of the second helical blade. During an acid-hydrocarbon separation process, by using the mixer of the present invention, the amount of alkali liquor used in an alkali washing process and the salt content in washing water produced after water washing can be greatly reduced.
