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.
