3 is another embodiment of the seawater warming system of the present invention.

The seawater heating system (100) of the present invention comprises an oil tank (110) in which oil is stored, a boiler (120) for heating the oil, a heat exchange And an outlet for discharging seawater heated by the oil, which is an object to be heated, in the heat exchanger (130) is formed in the heat exchanger (130), and the inlet and the outlet An inlet pipe 131 and a discharge pipe 132 are installed and magnets are installed in the inlet pipe 131 and the outlet pipe 132, respectively.

In addition, the venturi pipe 140 is installed in the discharge pipe 132 so that the sea water heated by the heat exchanger 130 includes air.

Hereinafter, the seawater heating system of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of a seawater heating system of the present invention.

The seawater heating system 100 according to the present invention includes an oil tank 110 in which oil is stored, a boiler 120 for heating the oil, and an oil- And a heat exchanger (130).

The oil stored in the oil tank 110 flows into the boiler 120 and then is heated and then flows into the heat exchanger 130 and is transferred to the oil tank 110. That is, (110), the boiler (120), and the heat exchanger (130).

The boiler 120 used in the present invention generally comprises a boiler body, a combustion chamber, a combustion device, a control device, and the like, and is an apparatus for generating hot water by flame, combustion gas or the like.

The heat exchanger 130 used in the present invention is a device for exchanging heat between two fluids. The heat exchanger 130 exchanges heat with a fluid having a low temperature through a heat transfer wall from a fluid having a high temperature.

Meanwhile, the heat exchanger 130 is formed with an inlet through which the seawater flows and an outlet through which the seawater heated in the heat exchanger 130 is discharged. The seawater introduced into the heat exchanger 130 is heat- And then fed into the aquarium.

The inlet of the heat exchanger 130 is provided with an inlet pipe 131 for introducing seawater from the outside, and a magnet is coupled to the inlet pipe 131.

The seawater has higher electrical conductivity than clean water. In the present invention, the N pole magnet is coupled to the outer circumferential surface of the inflow pipe, and the S pole magnet is coupled to correspond to the N pole magnet. So that attraction force acts between the N pole magnet and the S pole magnet.

Accordingly, the water molecules of the seawater transferred into the inflow pipe are subdivided by receiving the magnetic force while passing through the inflow pipe, and have effects on purification power, sterilization power, corrosion inhibition and the like.

In addition, a zinc ring is connected to the outer circumferential surface of the inflow pipe as an anode for preventing rust, and when the current flows between the two electrodes with the electrolyte solution in between, the current flows out to the electrolyte solution The zinc ring is first corroded when it comes into contact with the electrolytic solution in a state of being electrically connected to other metal, thereby delaying the corrosion of the inlet pipe.

That is, the zinc ring prevents corrosion of ions between dissimilar metals and prevents corrosion of the outer circumferential surface of a transfer pipe (not shown) through which the seawater introduced into the heat exchanger 130 directly contacts through the inlet pipe, Is prevented from being contaminated by heavy metals.

It is preferable that the inflow pipe, the discharge pipe, the oil transfer pipe and the like are made of a material having excellent corrosion resistance in order to prevent corrosion by seawater.

Meanwhile, the sea water discharged to the discharge pipe 132 of the heat exchanger 130 passes through the venturi pipe 140 to generate bubbles due to turbulence.

2 (b) is a side sectional view of the venturi tube, and FIG. 2 (c) is a cross-sectional view of the venturi tube. FIG. 2 1 is a front sectional view of a venturi pipe.

2, the venturi tube 140 of the present invention includes a seawater inlet 141 connected to the discharge pipe 132 of the heat exchanger 130 and an air inlet 142, and a discharge port 143 through which air is discharged together with seawater.

The inside of the venturi tube 140 has a shape gradually increasing toward the discharge port 143 side so that the inside diameter of the venturi tube 140 gradually increases. On the side of the other end of the discharge port 143, The venturi tube 140 is connected to the discharge pipe 132 of the venturi pipe 140 and the seawater inlet port 141 is connected to the venturi pipe 140. The other end of the venturi pipe 140 is connected with the seawater inlet port 141, And an air inlet 142 into which air flows is formed.

The air inlet 142 is preferably provided with a compressor to smoothly supply air into the venturi tube 140.

Accordingly, as described above, the diameter of the passage hole through which the fluid passes is formed to be wider from the front to the back, due to the characteristics of the venturi pipe (140).

Therefore, when the inflow air is directed toward the discharge port 143, the seawater introduced into the seawater inflow port 141 is sucked together, and bubbles are generated in a state where the seawater and the air are mixed, .

Particularly, the seawater inlet port 141 is installed on the upper part of the venturi pipe 140, and is installed eccentrically to the left and right, rather than the direct part of the diameter of the venturi pipe 140.

Therefore, when the seawater is drawn into the interior of the venturi pipe 140 through the seawater inlet 141, it strikes against one wall surface of the passage hole formed in the venturi pipe 140, and turbulence is generated in the incoming seawater.

3 is another embodiment of the seawater heating system of the present invention.

3, a protruding member 144 is formed on the inner surface of the venturi pipe 140 in the downward direction of the seawater inlet 141 so that seawater received from the seawater inlet 141 directly hits the protruding member 144 So that more turbulence is generated.

Particularly, the shape of the protruding member 144 is triangular in shape, so that the area of the protruding member 144 increases toward the discharge port 143 side of the venturi pipe 140 so as not to interfere with the flow of air flowing from the air inlet 142.

A plurality of the projecting members 144 may be formed along the inner circumferential surface of the venturi tube 140 while being spaced apart from each other by a predetermined distance.

With this configuration, bubbles are further generated.

A turbulence inducing member having the same shape as that of the projecting member 144 is provided on the inlet side of the inflow pipe 131 so as to cause turbulence in the seawater flowing into the heat exchanger 130 in the heat exchanger 130 .

This is to prevent turbulence from being induced in the heat exchanger 130 so as to reduce the accumulation of floating matter on the outer surface of the oil transfer pipe installed in the heat exchanger 130, thereby preventing corrosion.

Accordingly, the present invention has a remarkable effect in preventing corrosion of the heat exchanger to prevent contamination of marine organisms from heavy metals, reducing facility cost, and heating seawater efficiently and hygienically.
