MVR蒸發器概述/MVR evaporator overview
       MVR是蒸汽機械再壓縮技術(mechanical vapor recompression )的簡稱。
       MVR其工作過程是將低溫位的蒸汽經壓縮機壓縮,溫度、壓力提高,熱焓增加,然后進入換熱器冷凝,以充分利用蒸汽的潛熱。除開車啟動外,整個蒸發過程中無需生蒸汽從蒸發器出來的二次蒸汽,經壓縮機壓縮,壓力、溫度升高,熱焓增加,然后送到蒸發器的加熱室當作加熱蒸汽使用,使料液維持沸騰狀態,而加熱蒸汽本身則冷凝成水。這樣原來要廢棄的蒸汽就得到充分的利用,回收潛熱,提高熱效率,生蒸汽的經濟性相當于多效蒸發的30效。為使蒸發裝置的制造盡可能簡單和操作方便,可使用離心式壓縮機、羅茨式壓縮機。這些機器在1:1.2到1:2壓縮比范圍內其體積流量較高。 蒸發設備緊湊占地面積小所需空間也小。又可省去冷卻系統。對于需要擴建蒸發設備而供汽,場地不夠的現有工廠供水能力不足,特別是低溫蒸發需要冷凍水冷凝的場合,可以收到既節省投資又取得較好的節能效果。
MVR is the abbreviation of mechanical vapor recompression.
MVR its work is the low temperature of the steam by the compressor compression, temperature, pressure increases, increased enthalpy, and then into the heat exchanger condensation, in order to take full advantage of the latent heat of steam. In addition to the start of the car, the entire evaporation process without the need for steam from the evaporator out of the secondary steam, the compressor compression, pressure, temperature increases, the enthalpy increases, and then sent to the evaporator heating chamber as heating steam, So that the feed liquid to maintain the boiling state, while the heating steam itself is condensed into water. So that the original steam to be abandoned to be fully utilized, the recovery of latent heat, improve thermal efficiency, raw steam economy is equivalent to multi-effect evaporation of 30 effect. For the manufacture of the evaporator as simple as possible and easy to operate, a centrifugal compressor, a Roots compressor may be used. These machines have a higher volume flow in the 1: 1.2 to 1: 2 compression ratio range. The compact space for the evaporation equipment is also small. But also save the cooling system. For the need to expand the evaporation equipment for the steam, the site is not enough existing plant water supply capacity, especially low-temperature evaporation needs of frozen water condensation occasions, you can receive both to save investment and achieve better energy efficiency.

3, a high degree of automation: I designed the MVR evaporator automatic control system, the entire evaporator only in the control room can operate a person, reducing labor costs and improve product quality.
4、壓縮機選型:蒸發量0.2~2T一般選用低速羅茨壓縮機,2T以上選用高速離心式壓縮機。
4, the compressor selection: evaporation of 0.2 ~ 2T general selection of low-speed Roots compressor, 2T above the choice of high-speed centrifugal compressor.

MVR蒸發器應用行業/MVR evaporator application industry
       1、處理工業廢水(環保領域)
       工業廢水的濃縮和水的循環再利用。如電鍍行業、涂料生產行業、醫藥和農藥行業、金屬加工行業、造紙行業和原油生產行業等污水處理。從污水中去掉有機物和無機鹽。變廢為寶。如何低成本解決高含鹽工業廢水回用問題,是眾所知難題,MVR蒸發器是處理這類工業廢水的最佳方案。
       2、化工工業
       生產空心纖維分子的工藝用水的處理、香料的提純、亞氯酸鈉和過硫酸鈉等化工原料的生產、海水的淡化、有機添加劑的濃縮和結晶、提取液的精煉、把反應生成物分析成溶劑和產品。
       3、制藥工業
       我國的制藥行業,是個傳統的行業,使用了大量的老化、舊式蒸發器,不僅降低藥品質量,更是浪費了大量的能源,急需升級換代減少二氧化碳的排放。MVR還用于生產西藥的蒸發、濃縮、結晶和干燥,中藥的濃縮。
       4、食品行業
       在食品深加工行業,大量采用蒸發技術實現脫水的功能。如濃縮玉米漿和提取葡萄糖、氨基酸等。從果膠中提取的異丙醇的濃縮、芳香物的提取和濃縮、食品與發酵香料的分餾沉淀物、溶劑的精煉
       5、制酒工業
       制酒行業我國是個古老的行業。MVR蒸發器可以代替陳舊的蒸餾用的設備。
       6、牛奶行業
       因為牛奶行業需要的低溫、高度清潔、高度自動化等特點決定了傳統的蒸發器很難達到這些要求,所以才有MVR蒸發器的大力發展的機遇。
