Overview

The principle of MVR evaporator is the mechanical re compression of secondary steam, which uses a steam compressor to re compress the evaporated secondary steam to increase its temperature and reuse it. In theory, MVR evaporators do not require the consumption of steam, only electricity. The MVR wastewater evaporator is developed for the treatment of difficult to treat wastewater such as high salt, high COD, and high boiling point generated in the production processes of chemical, smelting, and pharmaceutical industries.

Product Details

There are three types of industrial waste: wastewater, waste liquid, and exhaust gas. Untreated wastewater can cause chemical pollution when discharged directly, leading to eutrophication of water bodies, air pollution, and a series of impacts on water sources. It poses a threat to human safety and seriously affects people's living and health levels. Therefore, environmental governance is urgently needed.

In many chemical production processes, salt containing wastewater is generated, mainly composed of sodium chloride, sodium sulfate, ammonium sulfate, ammonium chloride, etc. If discharged directly without treatment, a large amount of sewage will seep into the groundwater layer, causing serious pollution to the groundwater source, damaging the ecological environment, and endangering human health.

The evaporation of chemical wastewater evaporator is a process that uses heating to keep non-volatile impurities in the solution for evaporation and concentration. It is widely used in pharmaceutical production, and the evaporation equipment is generally called chemical wastewater evaporator. It has a wide range of structures and types, and has a long history of development. Chemical wastewater can also be treated by other methods, thus forming a specialized chemical wastewater evaporator for treating chemical wastewater. It can remove impurities and obtain pure solvent or semi-finished products, such as seawater desalination, and can also treat industrial wastewater. Its operating principle is simple and easy to use, and chemical wastewater evaporators are also a good choice for treating industrial wastewater.

Due to the high salt content in wastewater, methods such as biochemical treatment and catalytic oxidation cannot achieve desalination effect. However, desalination methods such as membrane filtration and ion exchange have poor desalination effect and operability for saltwater containing a large amount of organic matter and high concentration; Although traditional kettle type evaporation desalination or multi effect evaporator can crystallize sodium chloride, ammonium sulfate, etc. through evaporation, the operating cost is high and it is difficult for enterprises to afford. Therefore, the key issue in the treatment of high salt wastewater in the chemical industry is to reduce energy consumption and operating costs.

Based on the salt content of chemical production wastewater, we adopt the method produced by our companymvrWastewater evaporatorBy using the MVR evaporation principle, sodium chloride, ammonium sulfate, sodium sulfate, and other substances in wastewater can be evaporated and crystallized at the lowest possible cost. The salt obtained through solid-liquid separation can be sold as a by-product, and the condensed water evaporated can be reused as production water, achieving the effect of closed-loop water circulation and sewage treatment. After actual operation in the factory, the effect is ideal and the operating cost is low, which has been recognized by the using enterprises.
