MVR Evaporator for RO wastewater concentration, potassium chloride

MVR Technology
MVR applied mechanical vapor recompression unit for compressing the secondary vapor so that recycle the secondary vapor completely in a closed-loop circulation system. As a result of the vapor compressor, temperature and pressure of the secondary vapor raised, the heat efficiency boosted. The effectiveness of live steam is equal to 30 effects of multiple effect evaporator. Thus reducing the demand for external live vapor and cooling resources, energy conservation and less pollution attained.

Application Range

Concentration, crystallization, Industrial wastewater treatment, ZLD system, Juice/Jam/diary concentration, Chemical crystallization etc.

System components

Evaporator, separator, condenser, vacuum and discharging system, delivery pump, groundwork, PLC, electrical appliance and instruments, valves, pipelines etc.

Features

• MVR energy conserving evaporator is the advanced evaporation technology in nowadays. It only consumes a few vapors in the first two hours of the evaporator operation, almost no vapor consumption after then.
• As a compressor provided with thermal energy, compared with the traditional evaporator, MVR evaporator got a low temperature-trip, which is good for feeding material quality and avoiding scale forming.
• Not required a condenser or required a very small condenser
• CIP cleaning system
• Evaporation temperature: 50-100 C, less effect on feeding material nature
• Energy consumption: Evaporating 1-ton water shall consume 15-27 degree power, while the material with low boiling point, the consumption shall be below 20 degrees.  About the energy consumption depends on local vapor and power cost. We suppose the vapor supply cost 180 RMB/T, electricity supply cost 0.7 RMB per degree. Evaporating one-ton water will conserve 0.23*180-20*0.7=27.4 RMB. If you evaporating 100Tons, the evaporator is supposed to run 330 days every year, 24hours per day, MVR will save 27.4*100*24*330=21700800 RMB. The energy conservation efficiency is 60% more than five-effect evaporator.

Evaporator selection notice

• 2. MVR invest more than multi-effect evaporator at the early stage, but the cost shall be covered after 300days service.
