The domestic mechanical processing industry extensively uses emulsions, and their waste liquid has always been a serious environmental pollution problem that has not been effectively solved. In the past, domestic research on the treatment of waste liquids mainly focused on oil-based emulsions, with a focus on addressing COD and oil discharge pollution issues. At present, the commonly used waste lotion treatment processes are mainly oil separation, air flotation, aeration, microbial oxidation and other processes. These processes often have slow treatment speed, complex process, long process, large area, and difficult treatment effect to meet the national purified water discharge standards. With the increasing popularity of water-based cutting fluids, existing treatment technologies are becoming more difficult to meet the needs of new waste liquid treatment.

In order to overcome the shortcomings of the existing technology, Jetcrystal Energy provides a MVR treatment technology for waste emulsion, which realizes the separation of waste lotion through the self circulation of equipment. The specific process is as follows: the preheated emulsion enters the main heat exchanger, and after heating, evaporation, and concentration, the distilled water formed by steam condensation flows into the distilled water tank. The secondary steam and concentrated liquid enter the gas-liquid separator together, and the separated secondary steam is introduced into the mechanical compressor. The secondary steam is compressed, heated, pressurized, and introduced into the main heat exchanger for repeated circulation, thereby saving energy, reducing costs, improving production efficiency, and reducing environmental pollution.

The emulsion MVR evaporation and concentration equipment provided by Jiejing Energy separates water emulsion through system self circulation, and the concentrated emulsion can be recycled as fuel. The separated water can be discharged in compliance with standards after simple post-treatment. Jiejing Energy's emulsion MVR evaporation and concentration equipment has been successfully put into operation for more than two years, with stable operation, meeting design requirements, and achieving good economic benefits.
