[

This will be described in more detail below for each configuration.

First, the drum 100 is a portion forming an outer appearance of the drum type fluid heating apparatus according to the embodiment of the present invention.

The drum 100 is installed in the oil tank (or an oil tank) (not shown) in the vessel while the upper and lower openings are formed as hollow cylinders.

In addition, the opened upper surface of the drum 100 is closed by the upper cover plate 110, and the opened bottom surface of the drum 100 is closed by the lower cover plate 120.

A plurality of through holes 111 and 121 are formed in the cover plates 110 and 120 so that the upper end and the lower end of each fluid pipe 200 to be described later penetrate through the cover plates 110 and 120. In the center of the lower cover plate 120, A first coupling hole 122 is formed through the first cover plate 120 and a second coupling hole 123 is formed through the other side of the lower cover plate 120.

Here, the first coupling hole 122 is a portion for installing the injection pipe 300 to be described later, and the second coupling hole 123 is a portion for installing the steam outlet pipe 500 to be described later .

In addition, it is further provided that at least one heat transfer plate 600 is formed on the outer circumferential surface of the drum 100 in the form of a ring that surrounds the periphery of the drum 100. That is, through the additional provision of the heat transfer plate 600, it is possible to improve the heat conduction performance with the oil in the oil tank existing around the drum 100, thereby further heating the oil, .

Reference numeral 130 denotes a base for mounting the drum 100 in the oil tank.

Next, each fluid pipe 200 is a portion forming a flow path for guiding the flow of oil in the oil tank.

That is, oil flowing through the fluid pipes 200 through the fluid pipes 200 can be heated by the high-temperature steam existing in the drum 100 while passing through the inside of the drum 100.

At this time, the oil flow into each fluid pipe 200 is naturally performed by the convection phenomenon depending on the temperature difference between the oil present in the oil tank and the oil present in each fluid pipe 200.

Each of the fluid pipes 200 is installed along the circumferential portion of the drum 100. The upper end and the lower end of the fluid pipe 200 are connected to the upper cover plate 110 of the drum 100, 121 and the fluid pipe 200 are welded to each other through the through holes 111 and 121 formed in the upper cover plate 120 and the lower cover plate 120. The joints between the through holes 111 and 121 and the fluid pipe 200 are welded and tightly sealed .

Next, the injection pipe 300 is a portion configured to inject steam into the drum 100.

The injection pipe 300 is composed of a hollow pipe, and a perforated pipe having a plurality of injection holes 310 penetrating the peripheral surface thereof. In addition, the injection pipe 300 is vertically installed in the drum 100, and the lower end of the injection pipe 300 passes through the first coupling hole 122 formed at the center of the lower cover plate 120.

At this time, each fluid pipe 200 is configured to be disposed along the periphery of the injection pipe 300 around the injection pipe 300.

That is, the steam flowing into the injection pipe 300 is uniformly sprayed to all the parts of the drum 100 through the injection holes 310, so that the heating of each fluid pipe 200 can be performed uniformly So that thermal shock to each fluid pipe 200 can be prevented.

Particularly, in the embodiment of the present invention, it is shown that the vertical height of the injection pipe 300 is lower than the vertical height of the drum 100. Considering that the injection pipe 300 simply supplies the steam into the drum 100, the upper cover 110 is formed so as not to penetrate through the upper cover 110, And the welding work for maintaining confidentiality can be omitted.

In addition, the upper surface of the injection pipe 300 is formed to be closed and the bottom surface thereof is opened. The reason for closing the upper surface of the injection pipe 300 is that when the upper surface of the injection pipe 300 is opened, most of the steam is discharged through the corresponding part, It is most preferable to close the top surface of the injection pipe 300 for injection.

At this time, the open bottom surface of the injection pipe 300 is installed to penetrate through the first engagement hole 122 of the lower cover plate 120.

Next, the steam inlet pipe 400 guides the steam to the injection pipe 300.

Next, the steam outflow pipe 500 is a portion for guiding the steam flowing in the drum 100 to flow out.

One end of the steam outflow pipe 500 is connected to the space inside the drum 100 through the second coupling hole 123 formed in the lower cover plate 120 and the other end is connected to the steam flow Lt; / RTI >

Of course, the steam outlet pipe 500 may be configured to communicate with the space inside the drum 100 through the lowermost peripheral surface of the drum 100.

Meanwhile, when the drum type oil heating apparatus according to the embodiment of the present invention is provided in a plurality of oil tanks, the steam inlet pipe 400 and the steam outlet pipe 500 described above must be provided to both the drum type oil heating apparatuses It is not. That is, the steam inlet pipe 400 of any one of the drum-type oil heating apparatuses constitutes the steam outlet pipe 500 of the other drum-type oil heating apparatus, so that the number of the steam inlet pipe 400 and the steam outlet pipe 500 May be minimized.

Hereinafter, the operation of heating the oil in the oil tank by the drum type oil heating apparatus according to the embodiment of the present invention will be described in more detail as follows.

First, the drum type oil heating apparatus according to the embodiment of the present invention is installed in the oil tank.

In this state, since the internal space of each fluid pipe 200 constituting the drum type oil heating apparatus is in communication with the internal space in the oil tank, the oil present in the oil tank is also present in each fluid pipe 200 .

In this initial state, when high temperature steam is supplied through the steam inlet pipe 400, the steam is guided by the steam inlet pipe 400 and flows into the injection pipe 300 connected to the steam inlet pipe 400, And is sprayed into the space inside the drum 100 through the injection holes 310 formed in the injection pipe 300 in the course of the injection.

Therefore, the interior of the drum 100 gradually becomes a high temperature environment due to the influence of the steam, thereby heating the oil present in each fluid pipe 200.

When the oil in each fluid pipe 200 is heated by the above process, the fluid heated in each of the fluid pipes 200 flows into the oil tank, and the oil in the oil tank flows into the respective fluid pipes 200 200, the oil in the oil tank is gradually heated to maintain a constant viscosity.

In addition, when the high-temperature steam is supplied into the drum 100, the drum 100 is also gradually heated by the high-temperature steam, so that the oil in the oil tank is supplied to the respective fluid pipes 200 The temperature of the drum 100 can be increased by heat exchange without passing through the drum 100. Considering that a plurality of heat transfer plates 600 are further provided on the outer circumferential surface of the drum 100, heating of the oil in the oil tank is more smoothly performed due to the increase in the heat conduction area between the drum 100 and the oil .

On the other hand, the drum type oil heating apparatus of the present invention is not limited to the structure of the foregoing embodiment.

That is, although not shown, a jet pipe 300 constituting a drum-type oil heating apparatus of the present invention is formed to penetrate through the center of the upper cover plate 110, a bottom surface of the jet pipe 300 is formed to be closed In addition, the upper surface may be open and the steam inlet pipe 400 may be connected to the open upper surface of the injection pipe 300.

As a result, the drum type oil heating apparatus of the present invention is configured such that the high-temperature steam injected into the drum 100 through each of the spray holes 310 of the spray pipe 300 is concentrated and supplied to the fluid pipe 200 The fluid pipe 200 is uniformly sprayed toward all the fluid pipes 200 so that the thermal shock provided by each fluid pipe 200 is insignificant and the durability is not reduced due to such thermal shock.

In addition, as all of the fluid pipes 200 are uniformly heated, the oil in the oil tank flows uniformly to all of the fluid pipes 200, thereby intensively heating the fluid pipe 200, resulting in an excessively low viscosity The phenomenon of losing can be prevented.

In addition, the drum type oil heating apparatus of the present invention can further improve the heating performance against the oil in the oil tank by the additional structure of the heat transfer plate 600 provided on the outer peripheral surface of the drum 100.
