Abstract

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.

Description

SEA-WATER SALT-PLANT WITH OVERFLOWING SLABS
INVENTION DESCRIPTION
1. FIELD OF APPLICATION
The invention relates to sea-water salt-plant with overflowing slabs, intended for yielding of larger quantities of sea salt by benefitting from horizontal air streams. In the International Patent Classification, it is classified as Section E - Fixed Constructions; Class E04 - Building; Subclass E04H - Pools; Group 4/00, that includes various pools.
2. TECHNICAL PROBLEM
Since the wind power is taking a special place in the development of new technologies, the wind streaming is to be used to the maximum in salt production as well.
The technical problem solved by this invention relates to the structure and position of salt-plant slabs aimed to better utilisation of natural wind flow, enabling thus larger, more economic and efficient sea-salt production.
3. STATE OF THE ART
The sea salt (NaCI) is still being produced in salt-plants built in the Middle Ages or even earlier, their structure and location corresponding to the then state of technology. The pools have been built on flat grounds, with no protection against rain. A rain will decrease the quantity of the crystallised sea-salt, productivity and product quality. In the current endeavours to increase the sea-plant production, the air flow has not been used to the fullest extent possible. Such salt plants are usually built protected from the wind.
4. ESSENCE OF THE INVENTION
The essence of the invention is a salt-plant with a pool and one or more horizontal or titled overflowing slabs, placed in one or more columns above the pool. Mutually and relative to the pool, the overflowing slabs may be parallel or under opposite angles. The operating principle of the sea-water salt-plant with overflowing slabs is the constant exposure of a thin layer of sea water to wind streams that evaporate the water aimed to obtaining larger quantities of salt over a shorter period of time, the salt settling in the pool.
The sea water is supplied to the slabs and its constant circulation over the overflowing slabs is obtained by a piping distribution equipped with valves and a pump. Given the plant location, the most economic pump powering would be by wind.

6. DESCRIPTION OF THE INVENTION EMBODIMENT AND FUNCTIONING
The sea-water salt-plant with overflowing slabs utilises wind stream to evaporate the sea water. Sea water is taken from the pool and flows in a thin layer continuously down one or more overflowing slabs mutually distanced and placed one above the other, in a vertical column above the pool. Wind flows between the slabs, evaporating the sea water. The process is continued as long as the entire sea water from the pool is crystallised into salt and set at the bottom of the pool. This way, the time required to obtain alt is significantly shorter.
The embodiment of the sea-water salt-plant with overflowing slabs depends on the terrain relief, aimed to the best possible utilisation of wind direction and force. Hence, the best locations are steep coastlines and cuttings.
Figure 1. shows schematically the operating principle of the sea-water salt-plant with overflowing slabs.
With regard to the number of pools, vertical columns and overflowing slabs in each of them, the sea-water salt-plant with overflowing slabs can be embodied in several variants. Here are shown only two variants:
Variant A, Figures 2., 3. and 4., is the sea-water salt-plant consisting of one pool and one vertical column of two overflowing slabs.
Variant B, Figure 7., is the sea-water salt-plant consisting of one pool and two vertical columns of two overflowing slabs each.
The overflowing slabs are situated and above the other in a vertical column, positioned horizontally or slanted. The overflowing slabs may be mutually parallel or slanted in opposite directions. This invention description illustrates mutually slanted overflowing slabs.
Pool is to accumulate water taken from the sea, where water evaporates and salt sets. The pool is filled with new sea water by a pump.
Where the salt-plant has only one overflowing slab, the sea water, after passing over the slab, flows into the pool. Where the salt-plant has several overflowing slabs, the sea water flows from one to another slab and, after that, into the pool.
Functioning of the invention by the variant A
The sea water 2 is pumped by the pump P1 into the pool 1, and by the pump P2, through the piping system 3, to the upper overflowing slab 4 that has side walls 5 directing the sea water to the transversal opening 7 across the bottom of the slab 4. The sea water 2 flows by free fall in a thin payer, over the overflowing slab 4, while so flowing exposed to the wind stream that evaporates a part of the water, whereas the remaining sea water passes through the opening 7 and falls to the overflowing slab 9, so that the thin layer of water is still exposed to the wind stream. On this slab too, effected by the wind stream, another part of water evaporate. After passing over the tilted overflowing slab 8, water flows through the opening 11, as a thin waterfall, into the pool 1 , where a part of the salt contained in the falling sea-water crystallises. The pump P2 continuously pumps the remaining sea water from the pool onto the upper overflowing slab 4, as long as all the sea water evaporated and the sea salt 12 from it crystallised and set in the pool 1.
After this, the set salt is collected from the pool, and the pool is filled with new sea water for the new salt production cycle.
The pool and the overflowing slabs may be of different shapes. The pool volume is dimensioned according to the volume of the sea water that is planned to be turned into salt in a single cycle.
Productivity of a salt plant with overflowing slabs is much greater than in classic salt plants. The uppermost overflowing slab has the hinged side covers 6 that may be lowered down into horizontal position. The lowest overflowing slab in the column may also have hinged side covers 6, removing any rain water that entered the system above and preventing its mixing with the crystallised salt.
In rainy weather, the pump P2 and supply of the sea water from the pool to the overflowing slab 4 are stopped, and the hinged side covers 6 and turned down, thus taking rain water out of the pool. This protects the already achieved degree of salt crystallisation in the pool, whereas rain makes no harm.
A larger number of overflowing slabs in a vertical column achieves larger and longer contact of the sea water with sea streams, this, in turn, enhancing the effect of horizontal air streams to water evaporation and yielding of larger quantities of salt. The entire salt production process, from starting the pump P1 to fill the pool with new sea water, starting the pump P2 to lift sea water from the pool onto the upper overflowing slab, turning the hinged covers 6 and 10 to take rain water away, and continuous lifting of the remaining sea water onto the overflow slabs until the entire sea water evaporated and crystallised salt is set in the pool, may be automated by means of known electronic and automation elements.

7. INVENTION APPLICATION
The invention application is made obvious in its description. Sea-water salt-plant with overflowing slabs is particularly economic if located in areas abounding in winds, regardless of the number of sunny days. These are various cuttings and steep coastlines.
The most economic powering of pumps at such locations is by wind or combined powering.
Experts will find obvious possibilities of numerous modifications and changes in the sea-water salt-plant structure according to this invention, without leaving the scope and spirit of the invention.
