Description
technical field [0001] The invention relates to the technical field of rectification, in particular to a high-gravity MVR heat pump rectification system. Background technique [0002] Heat energy consumption accounts for the largest proportion of energy consumption, and the temperature of most heat energy consumption in actual industry is lower than 100°C. Rectification is the main part of heat energy consumption. Due to the rise of energy prices, the advantages of traditional rectification are becoming less and less obvious. Moreover, commonly used energy-saving methods such as reducing the reflux ratio, changing trays and packing, and preheating raw materials are subject to various restrictions. [0003] The principle of heat pump rectification is to directly compress the vapor at the top of the rectification tower to obtain the vapor at the top of the tower with high temperature and pressure. At the same time, the use of high-pressure steam and cooling water is reduced....
