An automated continuous diesel anti-wear additive post-treatment system

Abstract

This utility model discloses an automated continuous diesel anti-wear agent aftertreatment system, including a steam-jacketed heated washing and stirring vessel, a first centrifugal pump, a shell-and-tube heat exchanger, a continuous liquid-liquid phase separator, a second centrifugal pump, and a third centrifugal pump. The steam-jacketed heated washing and stirring vessel is connected to the first centrifugal pump. The outlet of the first centrifugal pump is connected to the inlet of the shell-and-tube heat exchanger and the inlet of the continuous liquid-liquid phase separator, respectively. The shell-and-tube heat exchanger is connected to the steam-jacketed heated washing and stirring vessel. The oil phase outlet of the continuous liquid-liquid phase separator is connected to the second centrifugal pump, and the water phase outlet of the continuous liquid-liquid phase separator is connected to the third centrifugal pump. The shell-and-tube heat exchanger and the steam-jacketed heated washing and stirring vessel are combined with a circulation loop design, which improves heat transfer efficiency, accelerates the demulsification process, reduces water washing time, and uses the continuous liquid-liquid phase separator to replace the traditional static sedimentation, realizing dynamic continuous separation of oil and water phases and significantly shortening the phase separation time.
