Sleeve type fresh water sea salt coproduction system

Abstract

The invention discloses a sleeve type fresh water sea salt coproduction system, which comprises a heating cylinder (5), a seawater storage layer (3) and a fresh water storage layer (2) in sequential arrangement from inside to outside, wherein a sealing piston (15) capable of doing vertical and reciprocating movement is arranged inside the heating cylinder (5); a piston rod of the sealing piston (15) sequentially passes out of the top ends of the heating cylinder (5), the seawater storage layer (3) and the fresh water storage layer (2) to be connected with a mechanical transmission mechanism (14); the bottom of the heating cylinder (5) is of a funnel-shaped structure; the funnel-shaped structure sequentially passes through the back ends of the seawater storage layer (3) and the fresh water storage layer (2), and then, an opening is right aligned with a salt storage tank (9); a sweater inlet and a water vapor outlet (7) are formed in the wall of the heating cylinder (5). The sleeve type fresh water sea salt coproduction system provided by the invention has the advantages that materials are taken in site; reproducible energy sources are used in a way of taking actions that suit local circumstances to realize the combined production of fresh water and sea salt; the structure is compact; the cost is low; the energy is saved; the environment is protected.

Description

technical field [0001] The invention relates to a sleeve-type freshwater and sea-salt cogeneration system, which belongs to the technical field of renewable energy utilization. Background technique [0002] With the development of society and economy, traditional fossil energy is becoming increasingly exhausted, and environmental pollution is becoming more and more serious. The use of clean and pollution-free renewable energy for production and life has been vigorously advocated and practiced. At present, there are various seawater desalination technologies, including reverse osmosis, electrodialysis, pressure steam distillation, point evaporation, etc. Each of these methods and technologies has its own advantages and disadvantages, and most of them are only used for a single purpose. Produce fresh water to solve the dilemma of fresh water shortage, while ignoring the utilization of sea salt. The preparation of sea salt has a promising industrial application prospect, which...
