Overview

The MVR wastewater evaporation crystallizer mainly evaporates and crystallizes wastewater, separates saltwater, and adopts different evaporation processes according to different types of wastewater, such as MVR multi effect evaporation process, MVR forced circulation evaporation process, MVR falling film evaporation process, or MVR falling film evaporation process.

Product Details

　　1、 Application of MVR wastewater evaporation crystallizer:

A large amount of mixed high salinity water is generated in methanol plants and methanol to olefin projects in the chemical industry, and pre-treatment is needed to reduce the calcium and magnesium ion content to ensure the stability of MVR evaporator operation. In addition, organic matter has a significant impact on the system and needs to be reduced to below 300 to ensure system stability.

　　2、 MVR wastewater evaporation crystallizer process:

MVR evaporator is different from ordinary single effect falling film or multi effect falling film evaporators. MVR is a single evaporator that integrates multiple effect falling film evaporators. It adopts segmented evaporation according to the required product concentration. That is, when the product cannot reach the required concentration after the first pass through the effect, it is pumped by the vacuum pump at the lower part of the effect through the external pipeline of the effect to the upper part of the effect, and then repeatedly passes through the effect to achieve the required concentration.

　　3、 Working principle:

The MVR evaporator uses a compressor to increase the energy of the secondary steam, and utilizes the increased energy of the secondary steam to recover its latent heat. Specifically, the secondary steam generated by the evaporator is adiabatically compressed by a compressor to increase its pressure and temperature, and then sent as heating steam into the heating chamber of the evaporator for condensation and heat release. Therefore, the latent heat of the steam is recovered and utilized. Before entering the evaporator, the cold material absorbs the heat of the condensed water through a heat exchanger, causing its temperature to rise, while also cooling the condensate and completion liquid, further improving the utilization rate of heat.

Wastewater evaporation crystallizers are widely used for the evaporation, concentration, and crystallization of water or solutions in industries such as medicine, food, chemical, and light industry, and can be widely used for wastewater treatment in these industries.

The wastewater evaporation crystallizer is low-carbon and environmentally friendly, with materials that can be recycled, high thermal efficiency, low energy consumption, and energy savings, greatly reducing operating costs; Small temperature difference, less prone to scaling and corrosion, and extended equipment service life.
