Seawater desalination device

Abstract

The invention discloses a seawater desalination plant, and relates to the technical field of seawater treatment. The seawater desalination plant comprises a first heat exchanger, a flash chamber and an absorption heat pump, wherein seawater is introduced into an inner pipe of the first heat exchanger; the absorption heat pump is used for providing a heating medium for the first heat exchanger; and the heating medium is used for heating seawater in the first heat exchanger; an inner pipe outlet of the first heat exchanger communicates with the flash chamber and is used for introducing heated seawater into the flash chamber; the flash chamber can perform flash evaporation on the seawater to form vaporous water and concentrated seawater; the vaporous water is introduced into the condensation heat exchange pipe; the condensation heat exchange pipe is located in the flash chamber; and the vaporous water in the condensation heat exchange pipe can heat the seawater in the flash chamber; meanwhile, the gaseous water is condensed to form liquid fresh water; an outlet of the condensation heat exchange pipe is communicated with the absorption heat pump; and the absorption heat pump can absorb waste heat of the liquid fresh water. The seawater desalination device can improve the energy utilization rate in the seawater desalination process and reduce the production cost.

Description

technical field [0001] The invention relates to the technical field of seawater treatment, in particular to a seawater desalination device. Background technique [0002] The traditional freshwater production method needs to consume a lot of electric energy and fossil energy, and in the process of seawater desalination, the waste heat of freshwater and concentrated seawater cannot be fully utilized, which will not only affect the ecological environment but also is not suitable for the development of the current resource-saving society. Therefore, A new way of exploiting freshwater resources is urgently needed to resolve the current crisis. Contents of the invention [0003] The object of the present invention is to provide a seawater desalination device to solve the above-mentioned problems in the prior art, improve the energy utilization rate in the seawater desalination process, and reduce the production cost. [0004] To achieve the above object, the present invention p...
