Problems solved by technology

At present, the cost of converting seawater into fresh water is basically very expensive, and the conversion process has a single goal. The traditional seawater desalination conversion method needs to consume a lot of electricity and fossil energy, and a lot of energy will be wasted in the conversion process, which cannot be fully realized. Use various energies
Under the energy strategy proposed in recent years, the single-target and costly seawater desalination technology is no longer enough to match the environment-friendly sustainable development strategy in the current economy

Abstract

The invention provides a solar self-sufficient fresh water and sea salt co-production system and an operation method thereof, and relates to the field of solar energy utilization and seawater desalination salt production, wherein the solar self-sufficient fresh water and sea salt co-production system comprises a double-pipe heat exchanger, a medium-high temperature focusing type solar heater, a flash tank, a small steam turbine, a power generator, a pressure pump, a salting-out pool and a refrigerant circulation pipeline. The system is a self-sufficient system, electricity consumption required by operation of various pumps and compressors in the whole system can be met through solar energy and seawater electricity generation, and salt can be separated out while seawater is desalted. The solar self-sufficient fresh water and sea salt co-production system can realize multiple capacities of power generation, fresh water and salt separation, greatly improves the energy utilization rate in the seawater desalination process, greatly reduces the production cost, and has high economic operation efficiency.

Description

technical field [0001] The invention belongs to the field of salt extraction by utilizing solar energy and desalination of seawater, and in particular relates to a self-supporting freshwater sea-salt cogeneration system utilizing solar energy and an operating method thereof. Background technique [0002] With global warming and population growth, human demand for fresh water continues to rise. At present, the cost of converting seawater into fresh water is basically very expensive, and the conversion process has a single goal. The traditional seawater desalination conversion method needs to consume a lot of electricity and fossil energy, and a lot of energy will be wasted in the conversion process, which cannot be fully realized. Harness various energies. Under the energy strategy proposed in recent years, the single-target and expensive seawater desalination technology is no longer enough to match the environment-friendly sustainable development strategy in the current eco...
