Abstract

The invention provides an evaporating purification device. The evaporating purification device comprises a main body, a heat exchange part and a liquid distribution part, wherein the interior of the main body is provided with an accommodation space; a waste liquid inlet is arranged on the main body; the waste liquid inlet communicates with the upper part of the accommodation space; the heat exchange part is arranged inside the accommodation space and used for supplying heat for a waste liquid in the accommodation space; and the liquid distribution part is arranged at the waste liquid inlet and used for uniform liquid distribution. When the evaporating purification device works, the waste liquid enters the accommodation space from the waste liquid inlet, and uniform liquid distribution is realized through the liquid distribution part arranged at the waste liquid inlet, so the waste liquid uniformly contacts with the heat exchange part and is evaporated in real time; the phenomenon of scaling of partial positions of the heat exchange part due to nonuniform liquid distribution is effectively avoided; and the efficiency of purifying wastewater is improved.

Description

technical field [0001] The invention relates to the technical field of purification equipment, in particular to an evaporation purification device. Background technique [0002] Non-ferrous smelting wastewater is a high-hardness wastewater containing high salt content. The non-ferrous smelting wastewater also contains complex components such as organic matter, microorganisms, suspended solids, and heavy metal ions. Generally, membrane method + MVR technology (mechanical vapor recompression technology) is often used for purification. Among them, the membrane method has problems such as complicated pretreatment, high investment, low water production, and short membrane life. MVR technology has problems such as high energy consumption, high cost, and easy scaling. After a period of use, serious scaling, blockage and local corrosion will occur, which will reduce the water production rate of the evaporator and even fail to operate normally. Contents of the invention [0003] ...
