Centrifugal type MVR (Mechanical Vapor Recompression) heat pump evaporation system

Abstract

The invention discloses a centrifugal type MVR (Mechanical Vapor Recompression) heat pump evaporation system. The centrifugal type MVR heat pump evaporation system comprises an evaporation device, a first-stage vertical cyclone separator, an MVR heat pump, a compressor and a condensing device, wherein the compressor is connected to the middle part of the evaporation device through a second-stage horizontal cyclone separation device; a stock solution inlet is formed in the top position of the evaporation device; the top part of the stock solution inlet is also connected with a preheater; a temperature control device is also connected between the preheater and the second-stage horizontal cyclone separation device; the bottom position of the second-stage horizontal cyclone separation device and the position, which is close to an air outlet part, of the compressor are commonly connected with a residual solution collector; the top position of the residual solution collector is connected to an inlet position of the compressor; the bottom position of the residual solution collector is connected to the condensing device through a reflux pipe; the condensing device is connected with the evaporation device through a spraying device arranged in the evaporation device. According to the centrifugal type MVR heat pump evaporation system disclosed by the invention, the evaporation efficiency is high, meanwhile, warm start is fast, and repairing and maintaining are convenient.

Description

technical field [0001] The invention relates to the technical field of MVR evaporation, in particular to a centrifugal 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 will continue to increase, and by 2030 the emissions will be 27% higher than the current level. 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 takes energy-saving and environmental protection technology as the main conte...
