Abstract

The invention discloses an MVR heat pump evaporation system, which comprises a water vapor compression system, an evaporator, a separator, an energy storage water tank and a waste heat recovery system. The vapor outlet of the energy storage water tank and the vapor outlet of the separator are both in connection with the vapor inlet of the water vapor compression system, the vapor outlet of which is connected to the vapor inlet of the evaporator. The vapor outlet of the evaporator is connected to the vapor inlet of the separator, and the stock solution inlet and the concentrated solution outlet of the evaporator are both in connection with the waste heat recovery system. The MVR heat pump evaporation system provided by the invention recovers low grade waste heat, i.e. makes use of the energy storage water tank to convert hot water sensible heat into low-pressure vapor latent heat for recycling during starting, thus enhancing the start-up speed of the system, avoiding the influence of non-condensable gas air circulation in the system on compressor performance, recovering all the latent heat of secondary vapor generated in a solution evaporation process, saving primary energy, greatly reducing the energy consumption during solution evaporation, and avoiding pollution.

Description

technical field [0001] The invention relates to the technical field of industrial heat pump evaporation, in particular to an MVR heat pump evaporation system. Background technique [0002] With the growth of energy consumption, especially the strong growth of primary energy consumption, global carbon dioxide emissions continue to increase, and by 2030 the emissions will be 27% higher than today. Carbon dioxide emissions caused by primary energy consumption are the main cause of global warming. In order to alleviate the excessive consumption of fossil energy and the climate problems caused by it, many measures have been taken internationally to reduce carbon emissions. As the world's largest energy-consuming country, my country's energy-saving and emission-reduction tasks are arduous. In order to realize the promise of reducing carbon emissions, in the "Twelfth Five-Year Plan", my country has included energy-saving and environmental protection technologies as the main content...
