<p>The operating principle of the sea-water salt-plant with overflowing slabs is constant exposure of a thin layer of sea water to air streams, aimed to obtaining larger quantities of salt in as short period of time as possible. The sea-water salt-plant consists of the pool (1). Above the pool is the vertical column made of two or more overflowing slabs (4) and (8). The overflowing slabs may be positioned, mutually and relative to the pool, parallel or at mutually opposite angles. Using several tiers of overflowing slabs enables larger and longer contact of the sea water with wind streams. The overflowing slabs have hinged side covers (6) and (10) to take rain water (13) away from the pool. New sea water is supplied and its constant circulation over the overflowing slabs is maintained by pumps and distribution piping. Given the plant location, the most economic pump powering would be by wind. The embodiment of a sea-water salt-plant with overflowing slabs depends on the terrain relief, aimed to the best possible utilisation of the direction and force. Hence, the best locations are steep coastlines and cuttings. The entire salt production process in sea-water salt-plant with overflowing slabs may be automated by means of known electronic and automation elements.</p> |
