Multilayered evaporation/distillation pot type liquid purification device

Abstract

The invention relates to a multilayered evaporation / distillation pot type liquid purification device. The device comprises a plurality of pot bodies, wherein the pot bodies are fixedly arranged in a laminated mode; annular groove-shaped evaporation chambers of which the heads and the tails are separated are formed in the radial directions of the pot bodies; center holes communicated with one another and a plurality of recirculation holes are formed in the axial directions of the pot bodies; radial liquid leading-in micropores are formed on the inner wall of the head end of the evaporation chamber of the pot body in the uppermost layer; a liquid outlet is formed at the tail end of the evaporation chamber of the pot body in an upper layer, which corresponds to a liquid inlet formed at the head end of the evaporation chamber of the adjacent pot body in a lower layer; the liquid outlet and a gas outlet are formed at the tail end of the evaporation chamber of the pot body in the lowermost layer; the pot body in the uppermost layer is sealed by an end cover; and every pot body in the lower layer is sealed by the bottom of the adjacent pot body in the upper layer. The multilayered evaporation / distillation pot type liquid purification device has a scientific and rational structural design and a small size, is convenient to install and maintain, can fulfill the aim of maximizing purification efficiency on the premise of minimizing the size, and can effectively remove various volatile impurities from liquid so as to fulfill the aim of purifying the liquid, and installation space is saved.

Description

technical field [0001] The invention relates to a purification device for engine oil, in particular to a multi-layer evaporation / distillation tank type liquid purification device for separating and removing volatile pollutants contained in the oil based on the principle of evaporation. Background technique [0002] At present, there are various liquid separation and purification devices based on the principle of evaporation, which can evaporate, separate and remove volatile impurities from contaminated liquid. Most of these devices use thin-film evaporation, which means that as the liquid passes over a heated thin-film surface (evaporator pan), volatile impurities have a boiling point below the surface temperature of the evaporator pan and are separated by evaporation. These devices have been used to purify engine oil. [0003] At present, the oil purification devices using the above methods all have the following disadvantages: 1. The oil purification device of this thin-f...
