Cellulose wastewater evaporation crystallization device, Kang Jinghui evaporator editor and talk about cellulose wastewater evaporation crystallization device.
The cellulose wastewater evaporation crystallization device is mainly used to treat cellulose salty wastewater. The key problem of cellulose wastewater treatment is to reduce energy consumption and operating costs, so when designing a cellulose wastewater treatment plan, the equipment selection is generally based on the actual situation of the manufacturer and the actual situation of the plant. Whether the multi-effect evaporation process or the MVR evaporation process is used, it is to treat the cellulose wastewater to meet the wastewater discharge index.
Hydroxypropyl methyl cellulose wastewater mainly contains sodium chloride, high COD, and contains product cellulose and polyols in the organic components, etc., and the wastewater has a high endpoint boiling point and is difficult to treat. According to the characteristics of cellulose salty wastewater, Kang Jinghui designed a vaporization and crystallization device for HPMC (hydroxypropyl methylcellulose) salty wastewater, and adopted MVR evaporation process.
The MVR evaporator of the whole set of cellulose salty wastewater carries out MVR evaporation and crystallization treatment on the by-product salty wastewater of the workshop, and the sodium chloride is removed in solid form, and the obtained secondary condensate can be used for reuse in the workshop without supporting biochemical treatment processes.
After many improvements and upgrades, this device has successfully solved the problem of MVR evaporation residual liquid reduction, the residual liquid volume is extremely low, the residual liquid treatment method is improved, the system energy and heat recovery is sufficient, and the steam consumption of the system is not increased.
Cellulose wastewater evaporation crystallization unit
The emergence of cellulose wastewater evaporation crystallization device not only solves the problem of cellulose wastewater treatment, but also provides valuable by-products for industrial production, achieving a win-win situation of economic and environmental benefits. With the continuous improvement of environmental protection requirements, evaporation crystallization units will play a more important role in the field of wastewater treatment in the future.
