Description

Structure improved seawater evaporation device {SEAWATER EVAPORATOR OF STRUCTURAL IMPROVEMENT TYPE}

The present invention relates to a seawater evaporation device using wind and solar energy. In particular, the evaporation of seawater can be further accelerated by repeating the process of forcibly rotating the evaporation ropes and automatically releasing them when the rotation is released in a twisted state. This is a technology for a structurally improved seawater evaporation device.

In general, the salt production method employs a method of drawing seawater into a salt farm and then drying (evaporating) it to precipitate natural salt. In other words, seawater (seawater) is pumped into a roughly rectangular salt pan made by attaching a tile, plastic pallet, or ceramic pallet to the floor. Then, when the seawater evaporates under natural conditions by solar heat, the salt precipitates in the crystals of the salt pan. Salt is produced by collecting table salt and natural salt precipitated by evaporating seawater. Natural salt or table salt precipitated through evaporation of seawater contains calcium, magnesium and various trace minerals, which are good for human health. It is known to be beneficial.

However, the method of producing salt by drawing seawater into a salt farm and evaporating it is to install salt farms of approximately square area continuously, and the seawater drawn into the salt farm passes from one salt farm to the next salt farm and goes through the process of evaporation to produce salt. In the case of this method of producing salt from seawater, a relatively large area of salt farm land must be secured taking into account the evaporation rate of seawater, etc., so it may be difficult to install a salt farm in areas with limited salt farm land, and it may be difficult to install salt farm land on the coast. It is becoming increasingly difficult to secure land for salt farms due to development, and due to restrictions on the land for salt farms, salt farms cannot be suddenly increased when demand for salt is high, and salt farms cannot be suddenly reduced when demand decreases, so salt production Management is inefficient and salt productivity (production per unit time) is reduced due to a delay in the evaporation rate of seawater.

Technologies related to seawater evaporation devices to solve these problems include:

The structurally improved seawater evaporation device according to the present invention,

As seawater flows down the rope by gravity, moisture evaporates. Since the rope is formed in a three-dimensional shape by the holder and gripper, the evaporation surface area exposed to air and sunlight is maximized when seawater flows down the rope. The evaporation rate of moisture becomes as fast as possible, and as the evaporation rate of seawater becomes as fast as possible, the seawater concentration (i.e., the ratio of the amount of salt mixed in seawater) increases quite quickly, which causes salt to precipitate in the crystallization pond. The time can be shortened as much as possible, and as the salt precipitation time is shortened, it has the greatest advantage in salt productivity.

In addition, it has the effect of accelerating the evaporation rate of seawater by repeating the process of forcibly twisting the rope and releasing it upon release of the twisting motion.

In addition, the power to forcibly twist the rope is provided by using the discharge pressure of seawater, and the discharged seawater is supplied to the rope, which has the effect of maximizing efficiency while simplifying the driving structure.

Ultimately, the ropes 13 are inserted and fixed in the form of passing through each through hole 112, and the ropes 13 fixed in this way form a three-dimensional shape of approximately a diamond shape by each gripper 12.

And as shown in FIGS. 3 and 5, each gripper 12 has a circular ring structure and functions to bind the ropes 13 together. At this time, each gripper 12 may be made of a string or a metal C-shaped ring structure.

It wets the ropes 13, and in particular wets the upper side of the ropes 13, gradually flowing down the ropes 13 and evaporating.

As the seawater evaporates, it becomes concentrated water with a high salt concentration. By going through this evaporation process several times, concentrated water with an optimal salt concentration is obtained. The concentrated water thus obtained is transported along the drainage line 50, which will be described later, and is determined. It drains to the ground (60) side.

The twist unit 30 is

As shown in Figures 5 to 9,

By rotating each evaporation unit 10 in one direction to twist the ropes 13 and then releasing them, when released, the ropes 13 are unwound in the other direction and the seawater flowing down the ropes 13 is evaporated. In order to accelerate

Holding means (31) for fixing the lower ends of the ropes (13) of each evaporation unit (10),

A post (32) erected at both ends of the salt farm (1), arranged in every m row of each evaporation unit (10), and having a ┌┐ shape;

A rod 33 connected to the upper end of the ropes 13 of each evaporation unit 10 and rotatably mounted on the post 32, and
