Description

Technical Field [0001] The present invention relates to a manufacturing apparatus for high salinity seawater,

More particularly, the present invention relates to an apparatus for producing highly salted seawater having higher salinity than ordinary seawater.

Generally, water is sprinkled on the road by water spray or the like to remove dust generated by road work and the like.

However, when water is sprayed on the road in winter, there is a problem that the road is frozen and the vehicle or the pedestrian slips and a traffic accident occurs.

At this time, although the water is heated and sprayed on the road, since the outside temperature in winter is low, the temperature is lowered over time, and the road is finally frozen, so that the above problem can not be solved fundamentally.

On the other hand, when snow accumulates in winter, pedestrians and vehicles are difficult to drive, so snow is usually sprayed with chloride-based snow remover such as calcium chloride or sodium chloride for rapid snow removal. However, the conventional snow remover has a problem that raw material costs such as limestone and hydrochloric acid are required to produce calcium chloride.

Korean Patent Registration No. 10-1359996

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a method for reducing the cost of raw materials, The present invention is to provide a highly salt water producing apparatus capable of manufacturing seawater more rapidly, improving productivity, and preventing waste of resources by recirculating seawater.

According to another aspect of the present invention, there is provided an apparatus for manufacturing highly salted seawater, comprising: a main body having a seawater inlet formed at an upper side thereof for introducing seawater to produce highly salted seawater; A jetting portion formed below the seawater inlet and including a plurality of jetting nozzles for jetting inflowed seawater; A heat exchange unit provided below the jetting unit and heat-exchanged with seawater jetted from the jetting unit by receiving heat from the outside; And a horizontal partition plate having a plurality of through holes at a lower side of the heat exchange unit.

Here, the main body may be divided into an upper chamber and a lower chamber by the horizontal partition plate, and an outside air supply control unit may be formed at one side of the lower chamber to control the amount of air introduced into the lower chamber.

A salt meter may be disposed at a lower end of the lower chamber and an outer air supply control unit may be provided at one side of the lower chamber to adjust the amount of air flowing into the lower chamber by comparing the measured value of the salt meter with a reference value. have.

In this case, the injection unit is arranged horizontally with units having a plurality of spray nozzles arranged in a straight line spaced apart from each other by a predetermined distance, and the heat exchange units are horizontally arranged with a plurality of longitudinal heat exchange cells spaced horizontally .

The heat exchange unit includes a heat exchange pipe at the center and a plurality of heat radiation fins protruding radially outward from the circumferential surface of the heat exchange pipe and spaced apart from each other in the longitudinal direction, A bent end portion may be provided.

The heat exchange unit may include a plurality of inclined heat dissipation fins and a heat exchange pipe penetrating the center of the heat dissipation fin.

Here, a further circulation pipe connecting the main body and the seawater inlet may be provided, and a control valve controlled to open / close the circulation pipe according to the salinity value of the measured seawater may be provided.

A preliminary seawater evaporator is disposed at a front end of the main body, and may be connected to the seawater inlet.

Here, an auxiliary heat exchange unit for dividing the inside of the preliminary seawater evaporation tank into upper and lower parts may be formed, and an air injection part for spraying seawater in the form of droplets may be formed below the preliminary seawater evaporation tank.

As described above, according to the present invention, seawater can be manufactured into sea salt of high saltiness to be used for various purposes such as snow removal, sprinkling on the road, kimchi pickling, prevention of freezing of coal, and the like.

Since the freezing point of pure sea water is lower than that of pure water, there is less fear of freezing in winter. Therefore, the cost of raw materials such as limestone and hydrochloric acid is lowered to lower the production cost for the production of snow removing agent, Can be prevented more effectively and environmental pollution is prevented because the resources are circulated by utilizing seawater as it is without using any additive.

As the outside air is introduced into the main body by the outside air supply control unit and comes into contact with the seawater, the amount of evaporation is increased, so that seawater having high salinity can be obtained more quickly.

If the salinity of the seawater measured by the salinity meter is less than the standard value for the snow removal and the possibility of road icing is low, the inflow amount of the air can be controlled by the outside air supply control unit and the pressure difference between the upper and lower chambers So that the amount of evaporation increases as the time for which the seawater stays in the upper chamber is prolonged. Therefore, only highly salted seawater having a salinity equal to or higher than the above-mentioned standard value can be manufactured.

Accordingly, if sea water having a salinity less than the reference value is used, the snow removal may not be performed properly or the road may be frozen.

On the other hand, it is possible to obtain seawater having high salt resistance by setting the reference value of the salinity of the seawater according to the environmental conditions such as the snowfall amount and the temperature, thereby solving the problems such as re-icing and road icing during snow removal and reducing environmental pollution .

Since the upper and lower ends of the heat radiating fin protruding upward and downward of the heat exchanging unit are bent in opposite directions to each other so that the sea water injected by the radiating fin moves along the bent end of the radiating fin, Because of the extension, the amount of seawater evaporation can be increased and the salinity can be increased.

In addition, when the measured concentration of the salinity measuring device is less than the reference value, it is fed back to the heat exchange unit to prevent wasting of resources. Since the seawater having a salinity higher than the standard value is used, .
