Problems solved by technology

[0006] However, the shortcomings of the compressed steam distillation device also restrict its further development: (1) the price of the steam compressor is extremely expensive, and the oil-free technology is relatively complicated, resulting in reduced product reliability and difficult maintenance; (2) the device is a large-scale chemical equipment, Therefore, it is difficult to realize miniaturization and household appliances; (3) neither can avoid the corrosion of the secondary steam to the water vapor compressor, nor can it avoid the corrosion of the water vapor compressor to the secondary steam, and cannot handle corrosive solutions an...

Abstract

The invention discloses a condensed steam source heat pump driven multi-effect distillation process. The system integrates the condensed steam source heat pump and the multi-effect distillation process and is a cross-border product in the heat pump industry and distillation industry. Tail-effect secondary steam condensed latent heat is directly recovered by the condensed steam source heat pump, so that the effects of independently providing a heat source needed by first-effect distillation by a condenser and gradually utilizing the secondary steam condensed latent heat are achieved. Moreover, a systematic design of the condenser, a multi-effect still and an evaporator is realized, and the condensed steam source heat pump driven multi-effect distillation process is realized.

Description

[0001] (1) Technical field [0002] The invention relates to a multi-effect distillation process driven by a condensing steam source heat pump used in seawater desalination, food processing, beverage production, sewage treatment, water purification treatment, reclaimed water treatment, chemical industry, household water purification, commercial water purification, and household appliances . [0003] (2) Background technology [0004] Compressed vapor distillation device: Seawater is heated on the evaporation side of the evaporative condenser to distill secondary steam, which is compressed by the water vapor compressor to increase the pressure and temperature, and then re-entered into the condensing side of the evaporative condenser to be condensed as heating steam. The latent heat of condensation of fresh water is recovered at the same time to provide seawater distillation latent heat for its evaporation side, so that the driving energy consumption of the device is minimized; i...
