(1-安徽中烟工业有限责任公司蚌埠卷烟oration temperature. The power of MVR compressor was increased from 120 kW to 151 kW online, the temperature
difference of the secondary steam was increased from 0. 6 弋 to 1. 6 , and the steam consumption was decreased from 267 kg/h to 0 kg/h.
It was more economical than the use of steam to increase the compressor power, and the steam consumption could be decreased. The standard
coal could be saved 160 tons each year, the energy saving effect was remarkable.
Key words Reconstituted tobacco leaves by paper-making ; Evaporation temperature; Compressor power ; Energy-saving
机械蒸汽再压缩(MVR)技术是利用少量的电能将系统 蒸汽热量,汽化并产生二次蒸汽,进入上述循环过程。目前,
内产生的二次蒸汽升温升压反复利用,具有节能减排、工艺 对造纸法再造烟叶MVR蒸发系统的节能技术研究较少,
