Product Description
Mechanical Vapor Recompression
Evaporator MVR evaporator<1>We are a scientific manufacturer specializing in "zero discharge".the company cooperates closely with many domestic universities and well-known institues of industry.the company takes"zeron discharge"of industrial wastewater as the leading factor and MVR evaporator as the core.at present,the company 's incomplete set of industrial waste water treatment equipment has been in pharmaceutical chemical industry,pesticide chemical industry,dyestuff chemcial industry,rubberand plastic chemical industry,food chemical,petrochemical industry,flame retardant chemical industry,mechanical system etc <2> Laboratory Testing:The company is equipped with water quality analysis laboratory and 200L/h medium-sized sample machine. All design projects need to be tested in the early stage of the project, and pilot-scale experiments are carried out when necessary to ensure the stable operation of the project design.<3>The company independently develops and manufactures steam compressors to ensure the quality of MVR core components<4>PROCRSS INTRODUCTIONR & D background: As per different production process, the kinds and chemical properties of organic matter in high salinity organic wastewater vary greatly, but most of the salts are Cl-, SO42-, Na+, Ca2+. If directly discharged,It would pollute the environment ; and the biochemical treatment process is more difficult to deal with. Although these ions are essential nutrients for microbial growth, they play an important role in promoting enzymatic reaction, maintaining membrane balance and regulating osmotic pressure in the process of microbial growth, but if the concentration of these ions is too high, they will inhibit and poison microorganisms. High salt concentration, high osmotic pressure and microbial cell dehydration in high-salt wastewater cause cell protoplasm separation; salting-out reduces dehydrogenase activity; high chloride ion is toxic to bacteria; high salt concentration and increased density of wastewater make activated sludge easy to float and drain, thus seriously affecting the purification effect of biological treatment system.High Salt Water Sources:High Salt Wastewater from Chemical Production Process

MVR evaporation chartTechnology Comapare:Conventional evaporation requires a lot of cooling water to cool the heat of secondary steam (make it condense), and then the heat of cooling water is released into the atmosphere through cooling tower, which not only consumes fresh steam, but also consumes a lot of circulating water and power (pump) operation, resulting in triple waste.
MVR technology can compress and reuse secondary steam which needs condensation to replace fresh steam. It not only avoids the use of fresh steam, but also completely abandons the cooling tower, greatly reduces operating costs, and truly achieves environmental protection, energy saving, water saving and cost saving.90%Compared with single effect, MVR can save 90% of the cost per tonTechnology Compare:No

| 6 | Application
| low boiling point arise,around 5-10ºC
| could evaporate higher boiling point material
|
| 7 | Effect on product quality
| Short stay time, low temperature differential evaporation, minimal impact on product quality
| The stay time is longer and the temperature is higher, which has little effect on the product quality.
