摘要/Abstract

摘要： 机械蒸汽再压缩(MVR)蒸发系统是一种高效节能的蒸发体系。本文采用降膜蒸发器为蒸发主体、罗茨压缩机为蒸汽压缩机, 并以水为实验原料研究了一套MVR蒸发装置。实验中以总蒸发水量和单位能耗蒸发水量(SMER)作为MVR蒸发系统的性能指标, 分别研究了进料温度、蒸发压强、压缩机频率对其影响。结果表明:最佳进料温度是蒸发压强下的饱和液体温度;最适蒸发压强与具体系统的蒸发能力和压缩机效率密切有关, 在压缩机效率保持较高水平的前提下, 适当降低蒸发压强有利于系统的节能;压缩机的频率直接影响系统的蒸发量和压缩机的功耗, 在压缩机允许的范围内增大压缩机频率, 单位能耗蒸发量是增加的。

关键词: 机械蒸汽再压缩, 进料温度, 蒸发压强, 压缩机频率

Abstract: Mechanical vapor recompression(MVR) evaporation system is a new energy efficient evaporation technology. This paper established a set of MVR evaporator device using water as raw material, falling-film evaporator as evaporating body, and roots compressor as steam compressors. This paper investigated the effects of feed temperature, evaporation pressure and compressor frequency on the evaporation of the total amount of water and specific moisture extraction rate(SMER), which is considered performance indicator of MVR. The results showed that the optimum temperature of the feed was the saturated liquid temperature at the evaporator pressure;the optimum evaporation pressure was closely related to evaporation capacity and compressor efficiency in specific systems;lower the evaporator pressure was beneficial to energy saving when maintaining a high level of efficiency of the compressor;frequency of the compressor directly affected evaporation of the total amount of water and compressor power; SMER increased with the increase of the frequency of the compressor within the allowable range.

Key words: mechanical vapor recompression(MVR), feed temperature, evaporation pressure, compressor frequency
