HRP20090001A2 - Salt evaporation pond with spillway cascade basins - Google Patents

Abstract

The way saltwater with overflow cascade basins is constructed depends on the configuration of the terrain for the best use of wind direction and strength. The best locations are steep shores and cuttings. A saltwater basin with overflowing cascade basins may have two or more pools lined up in a column. Overflow walls between adjacent pools in a column can be made under different oblique and vertical slopes. Sea salt pans, which are made in three variants, are described in more detail: Option A - Sea salt pans with overflow cascade basins with sloping overflow wall, Option B - Sea salt pans with cascade overflow cascades with vertical overflow ponds, and Variant C - Sea salt pans with overflow cascade pools with hair underlined by overflow wall. For the water supply to the pool, a pipeline (D) with non-return valves and a pump is used. The use of sloping and vertical overflow walls between multiple pools allows for greater and more frequent contact of the sea with wind currents, thus increasing the effect of horizontal air currents on the evaporation of water to produce larger amounts of salt.

Description

The field of technology

The invention relates to sea salt pans with overflow cascade basins for obtaining larger quantities of sea salt using horizontal air currents.

According to the International Patent Classification, the subject of the invention belongs to area E - construction, class E04 - high construction, subclass E04H - swimming pools and group E04H 4/00, which includes various swimming pools.

Technical problem

Since wind energy has a special place in the development of new technologies, this invention also proves how wind can be used as energy in the production of salt.

The technical problem that is solved by this invention relates to the construction and location of the basin for the salt pans, which will make better use of the natural flow of the wind and thus enable greater, more economical and more efficient production of sea salt.

State of the art

The production of sea salt /NaCl/ still takes place in salt pans that were built in the Middle Ages and earlier, and their construction and location were adapted to the state of the art of that time. The pools are built on flat ground.

In previous efforts to increase the productivity of salt pans, horizontal air currents were not fully utilized. Such salt pans are usually built in leeward areas.

The technological problem of such salt pans is the poor use of air currents, which can increase salt production.

The essence of invention

The essence of the invention is a sea salt pan with overflowing cascading pools.

There are overflow walls between adjacent pools that can be made at different slants and vertical slopes.

A sea salt house with overflowing cascade pools can be constructed with two or more pools in a column, most suitable on a steep coast and cuts.

Pipe distribution with valves and a pump is used to supply the sea to the pool and maintain constant circulation of the sea through the overflow walls. The most economical drive for the pumps, given the location of the salt pan, would be wind.

The use of sloping and vertical overflow walls between several basins enables a greater and more frequent contact of the sea with air currents of the wind, which increases the effect of horizontal air currents when evaporating water to obtain larger amounts of salt.

Description of the performance and way of functioning of the invention

The method of execution of the sea salt pan with overflowing cascading pools depends on the configuration of the terrain in order to make the best possible use of the direction and strength of the wind. For this purpose, the most favorable locations are steep banks and cuts.

A sea salt pan with overflow cascade basins must have two or more basins arranged stepwise in a column.

The pool in the sea salt works for the accumulation of sea water where the process of sea evaporation and salt deposition as the final product of production takes place.

Although sea salt pans with overflow cascade basins, due to the shape of the overflow walls between adjacent basins in the column, can be constructed at different slopes, in this description, sea salt pans constructed in three variants will be described in more detail, namely:

Variant A - sea salt pan with overflowing cascade pools with an inclined protruding overflow wall,

Variant B - sea salt pan with overflow cascade basins with a vertical overflow wall, and

Variant C - sea salt flat with overflowing cascade pools with a slope underlined by an overflowing wall.

The use of sloping and vertical overflow walls between several basins enables a greater and more frequent contact of the sea with air currents of the wind, which increases the effect of horizontal air currents when evaporating water to obtain larger amounts of salt. Pipe distribution D with non-return valves and a pump is used to supply the sea to the pool and maintain constant circulation of the sea through the overflow walls. The most economical drive for the pumps, given the location of the salt pan, would be wind. In the description of the invention, sea salt pans with overflow cascading basins in variants A, B and C with two basins and three forms of overflow walls are schematically shown.

On Fig. 1. and 2., variant A is shown - sea salt flats with overflow cascade basins with a slanted protruding overflow wall between the two basins. Sea salt pan A consists of: first pool 1, overflow partition 2, oblique projecting overflow wall 3, second pool 6, final partition 7, pipe distribution D for sea supply, which includes: suction basket 8, supply pipe 9 to non-return valve, non-return valve 10 , drain pipe 11 from the second pool, supply pipe 12 from the check valve to the pump, pump 13 and supply pipe 14 from the pump to the first pool.

On Fig. 3. and 4., variant B is shown - a sea salt pan with an overflow cascade basin with a vertical overflow wall between two basins. Sea salt pan B consists of: first pool 1, overflow partition 2, vertical overflow wall 4, second pool 6, final partition 7, pipe distribution D for sea supply which includes: suction basket 8, supply pipe 9 to the non-return valve, non-return valve 10, drain pipe 11 from the second pool, supply pipe 12 from the non-return valve to the pump, pump 13 and supply pipe 14 from the pump to the first pool.

On Fig. 5. and 6., variant C is shown - sea salt pan with overflow cascading basins and a sloping overflow wall between the two basins. Sea salt pan C consists of: first pool 1, overflow partition 2, sloped overflow wall 5, second pool 6, final partition 7, pipe distribution D for sea supply, which includes: suction basket 8, supply pipe 9 to non-return valve, non-return valve 10 , drain pipe 11 from the second pool, supply pipe 12 from the check valve to the pump, pump 13 and supply pipe 14 from the pump to the first pool. In order to increase the capacity, all three designs of sea salt pans, A, B and C, can have two or more basins in one column or a sea salt pan with several columns in a horizontal row.

Figure 7 shows Variant A – a sea salt pan with overflow cascade basins and slanted projecting overflow walls with five basins in a stepped column.

Figure 8 shows variant A – a sea salt pan with four vertical columns in a horizontal row. The most favorable locations for such sea salt pans are steep coasts 17 and cuts where there is always enough wind. The use of overflow cascade basins with overflow walls between several basins enables greater and more frequent contact of the sea with air currents of the wind, which increases the effect of horizontal air currents when evaporating water to obtain larger amounts of salt.

Mode of operation of the invention

The way the sea salt works, according to this invention, is explained on the design of the sea salt according to variant A, Fig. 1. and 9.

The procedure can be carried out in two ways:

The first method - After switching on, the pump 13 draws fresh sea 15, through the suction basket 8, supply pipes 9, 12 and 14 and enters it into pool 1. The non-return valve 10 is set so that the sea cannot enter pool 6 through pipe 11. When pool 1 is full, the sea flows into pool 6 via overflow barrier 2 and overflow wall 3. When pool 6 is filled with sea, non-return valve 10 closes the sea supply through pipe 9, and opens the sea supply through pipe 11 from pool 6. Now the pump 13 sucks the sea only from the pool 6 and through the pipes 12 and 14 it enters into the pool 1. This action is performed as long as there is fresh sea 15 in the pool 6. The air current passing over the layer of the sea 15, while overflowing over the overflow wall 3, contributes faster evaporation of the sea, and thus to a faster deposition of salt 16 at the bottom of basins 1 and 6. The described action stops when the entire amount of suctioned sea turns into salt. A smaller amount of salt also accumulates in pool 1.

Another way - the non-return valve 10 is set so that the pump 13 brings fresh sea 15 simultaneously to pool 1 and pool 6. When both pools are full, the fresh sea supply is closed, and the non-return valve 10 is turned to a position that allows it to pump through the pipe 11 it drains the sea from pool 6 into pool 1. After that, the sea will flow into pool 6 via overflow barrier 2 and overflow wall 3. This operation will be carried out as long as there is sea in pool 6, that is, until the entire amount of sea crystallizes into salt.

In the same way, the process of obtaining salt takes place in sea saltpans, which are designed according to variant B, with a vertical overflow wall 4, Fig. 2. and 10., and the sea salt pan according to variant C, with overflow wall 5 underlined, Fig. 3. and 11.

In the case of a salt pan with more than two pools in a column, Fig. 7., the non-return valves 10 are set so that the pump 13 first brings fresh sea 15 into the first pool at the top of the column, from which the sea flows into the next pool through overflow partitions and overflow walls, then through the next overflow partition and overflow walls into the next pool and so on until the last pool at the foot of the column. When the last pool is full, its non-return valve closes the fresh sea supply and opens the sea drain from that pool to the first pool. The same happens when the penultimate pool is filled, and so on until the second pool from the top of the column. When all the basins are full, the sea from the first and neighboring basins pours into the neighboring basins via overflow partitions and overflow walls. This cycle is repeated until the entire amount of fresh sea is turned into salt.

Even with such columns, the process can be carried out by first filling all the pools with fresh water and then closing the fresh sea supply, and continuing the process of draining the sea from the last to the first pool until all the amount of sea has turned into salt in all the pools.

The entire described procedure, from turning on the pump, suctioning fresh seawater, transferring seawater from pool to pool, filling with fresh water and other necessary actions, can be performed manually or fully automated with known automation elements.

Given that the mass of the sea, which has a certain potential energy, accelerates when pouring over the spillway walls, there is a possibility to place water turbines with blades at the base of the spillway walls that would turn the shafts of electric generators.

Application of the invention

The application of the invention is obvious from the description itself. Sea salt flats with overflow cascade basins with overflow walls will be very economical if located in an area with a lot of wind, regardless of the number of sunny days. These are various cuts and steep banks.

Concrete will be used to build the pool, although other materials are not excluded. The automation mode is fully possible.

To drive the pump in such locations, it is most economical to use wind or combined drive.
