Description
Technical Field
The invention belongs to the field of salt recovery, and particularly relates to a salt-containing liquid salt recovery device utilizing gas heat energy. Meanwhile, the invention also relates to a recovery method of the salt-containing liquid salt recovery device by utilizing gas heat energy.
Background
Extraction of salt from aqueous solutions is often a highly energy-consuming and time-consuming process requiring removal of water and salt crystals. Zero Liquid Discharge (ZLD) eliminates any waste liquid leaving the plant or facility boundary, recovering most of the water for reuse. However, ZLD has been technically considered feasible, but economically unfeasible, and has been applied only in limited situations. In recent years, the more clear recognition of the dual challenges of water shortage and aquatic environmental pollution has renewed global focus on ZLD. Stricter regulations, increased wastewater treatment costs, and increased freshwater value are driving ZLD to be a beneficial or even necessary option for wastewater management.
Early ZLD systems were based on a separate thermal process in which the wastewater was typically evaporated in a brine concentrator, followed by a brine crystallizer or evaporation pond. The condensed distillate water from the ZLD system is collected for reuse, while the resulting solids are sent to landfills or recovered as valuable salt by-products. Reverse Osmosis (RO), a membrane-based technology widely used in desalination of sea water, has been incorporated into ZLD systems to improve energy and cost efficiency. However, while RO has a higher energy efficiency than thermal evaporation, it can only be applied to feed waters with a limited salinity range. Thus, while ZLD has great promise for reducing water pollution and increasing water supply, its feasibility depends on the balance between revenue, energy consumption and operating costs associated with ZLD.
