Abstract

The invention relates to a plate-type vacuum membrane distillation evaporator and application thereof. The evaporator comprises a steam inlet side end plate on the left side and a steam outlet side end plate on the right side, wherein modules composed of a secondary steam channel sealing ring, a plate-type membrane frame, a feed liquid channel sealing ring, a heat exchange plate frame, a heater steam channel sealing ring, a heat exchange plate frame, a feed liquid channel sealing ring and a plate-type membrane frame are sequentially arranged and mounted between the steam inlet side end plate and the steam outlet side end plate from the left to right; and the multiple modules are sequentially connected to form a membrane stack by the secondary steam channel sealing ring. According to the application, multiple evaporators are combined into a high-efficiency and compact multiple-effect plate-type membrane distillation sea water desalination system. According to the plate-type vacuum membrane distillation evaporator and application thereof disclosed by the invention, gradient utilization ratio and thermal efficiency of membrane distillation vaporization latent heat are greatly improved, and the device has the advantages of compactness, high efficiency, high thermal efficiency, great water producing ratio and the like.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination and membrane separation, in particular to a plate-type vacuum membrane distillation evaporator and its application. Background technique [0002] Fresh water is one of the basic materials for the survival and development of human society. With the development of economy, the increase of population and the increasingly serious water pollution, many countries and regions have different degrees of water shortage problems, and the world is facing increasingly serious water problems. Resource crisis. [0003] Seawater desalination is one of the important ways to solve the crisis of freshwater resources. Technologies such as multiple-effect distillation, multi-stage flash evaporation, reverse osmosis, and freezing are often used for seawater desalination. As an emerging membrane separation technology, membrane distillation (MD) has attracted much attention in the field of seawater desali...
