Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultraviolet reactor,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultraviolet reactor for sterilizing ultraviolet (UV) water in a ballast water treatment apparatus of a ship. More specifically, the present invention relates to an ultraviolet And more particularly to a plurality of ultraviolet reactor connection structures for reducing the installation area.

In general, ballast tanks installed on ships are to minimize the center of gravity of the ship by loading and unloading of cargo to help safe navigation. In other words, if the ship is loaded full of cargo, the vessel's center of gravity is located below sea level even if the ballast tank is not filled with ballast water, so that the ship can safely navigate even if external force is applied. However, The ballast tanks are filled with ballast water so that a certain portion of the vessel can be positioned below the sea level.

As described above, the ballast water used for safe navigation of a ship has a problem in that it is used as a medium for propagating a creature or pathogen in a specific sea area to another sea area.

The ballast water filled in the ballast tank may contain various kinds of marine life and pathogens. Since the inflow and outflow of the ballast water occur in different areas, when the ballast water is introduced, As it flows out to other waters, causes side effects that disturb the environment and the ecosystem.

Therefore, introduction of facilities for treating marine organisms or pathogens contained in ballast water at the time of leakage of ballast water is obligatory.

Fig. 1 shows the construction of a general ballast water treatment apparatus.

As shown in FIG. 1, the ballast water treatment apparatus 1 is provided with a pretreatment filter 10 and an ultraviolet reactor 20, and is configured to sterilize the inflow or outflow of ballast water.

First, the inflow process of the ballast water will be described. In FIG. 1, the configuration indicated by "A" becomes the ocean, and the configuration indicated by "B" becomes the ballast tank.

When the ballast water is introduced, the valve 21 of the inlet pipe 11 and the valve 22 of the connection pipe 12 are opened and the valve 23 of the branch pipe 13 is closed. The seawater introduced from the ocean A flows into the pretreatment filter 10 through the inflow pipe 11 and is removed through the ultraviolet reactor 20 through the connection pipe 12, 14 to the ballast tank B.

Conversely, if the ballast water outflows, the configuration indicated by "B" in FIG. 1 becomes the ocean, and the configuration marked "A" becomes the ballast tank (ocean and ballast tanks are connected by a common line ). When the ballast water flows out, the valve 21 of the inlet pipe 11 and the valve 22 of the connecting pipe 12 are closed, and the valve 23 of the branch pipe 13 is opened. The seawater flowing out of the ballast tank A flows into the ultraviolet reactor 20 through the branch pipe 13 and is subjected to a sterilization treatment process and then discharged to the sea B through the discharge pipe 14.

The ballast water used in ships in accordance with the recent IMO (International Maritime Organization) agreement requires sterilization treatment.

Various methods such as electrolysis, heat treatment, ultraviolet light irradiation, and membrane separation can be applied to the sterilization treatment for the ballast water treatment. However, since the ultraviolet light irradiation treatment does not require addition of a chemical substance and is easy to control, .

The ultraviolet reactor 20 described above is for irradiating ultraviolet rays to seawater and has a plurality of ultraviolet lamps for irradiating ultraviolet rays. The seawater passing through the ultraviolet reactor 20 is sterilized by the ultraviolet rays irradiated from the ultraviolet lamp.

2 and 3 show an example of an ultraviolet reactor of a ballast water treatment apparatus developed by the present applicant, wherein Fig. 2 is a plan view and Fig. 3 is a front view.

2 and 3, the ultraviolet reactor 20 includes a hollow rectangular column-shaped body 30 provided as a passage through which sea water flows in the longitudinal direction, A seawater inflow pipe 40 and a seawater inflow pipe 45 connected to each other in a form extending in parallel to the longitudinal direction of the body 30 and a plurality of ultraviolet lamps 50 arranged to penetrate across the body 30, .

When the ultraviolet reactor 20 is installed horizontally with the ultraviolet reactor 20 having a cylindrical body, the ultraviolet reactor 20 can not be horizontally installed, And the ultraviolet lamp 50 is installed across the width direction of the body so that the ultraviolet lamp 50 is always installed horizontally as shown in the drawing, It is a form.

As shown in the drawing, the ultraviolet reactor 20 has a structure in which the width of the middle portion of the body 30 is wide to match the length of the ultraviolet lamp 50 across the sea, And the seawater inlet pipe 40 and the seawater outlet pipe 45 are arranged in parallel to each other in the longitudinal direction of the body 30 so as to be narrowed toward the inlet and outlet portions in order to fit into the discharge pipe passage 47, to be.

Because of this, it is necessary to further connect the curved pipes 42 and 46 for connection to the sea water introduction duct 43 and the sea water discharge duct 47, so that the construction is very complicated and difficult to manufacture and the height is too high, do.

When the plurality of ultraviolet reactors 20 are to be connected and used due to the increase of the seawater treatment capacity, the seawater inlet conduit 43 and the seawater outlet conduit 47 of each ultraviolet reactor 20 are returned to the common inflow conduit (Not shown) and a common discharge pipe (not shown). Therefore, the ultraviolet reactor and its connection structure should be complicatedly constituted by the bends 42 and 46, the sea water introduction duct 43, the sea water discharge duct 47, the common inflow duct and the common discharge duct, It takes up too much.

4 through 7, the ultraviolet reactor 100 includes a body 200 provided as a passage through which seawater flows, and an ultraviolet reactor 200 for introducing seawater into the body 200 from a marine or ballast tank (not shown) And includes a seawater inflow pipe 300, a seawater discharge pipe 400 for discharging the seawater passing through the body 200, and an ultraviolet lamp 500 for sterilizing the seawater passing through the body 200 by irradiating ultraviolet rays do.

Specifically, the body 200 is formed in the form of a hollow rectangular column in which both end portions in the longitudinal direction are opened.

The seawater inflow pipe 300 and the seawater inflow pipe 400 are disposed at both ends in the longitudinal direction of the body 200 in a direction parallel to the width direction of the body 200.

In the present specification and claims, the 'longitudinal direction' of the body 200 is a direction in which sea water flows or a direction connecting the sea water inflow pipe 300 and the sea water outflow pipe 400, Is a direction parallel to the long side when the cross section of the passage is rectangular, and the direction " height direction " is the direction parallel to the short side when the cross section of the passage is rectangular. In the case where the cross section of the passage is a square, any pair of opposite sides of the two pairs of opposing sides is in the width direction, and the other pair of opposite sides in the vertical direction is the height direction.

According to one embodiment, the seawater inlet pipe 300 and the seawater outlet pipe 400 are disposed in parallel with the width direction of the body 200 for stabilizing the flow of seawater, while considering connecting multiple ultraviolet reactors.

The plurality of ultraviolet lamps (500) are disposed in such a manner as to penetrate the hollow square columnar body (200) across the width direction, and sterilize by irradiating ultraviolet rays to seawater flowing in the body (200). The ultraviolet lamp 500 has a cylindrical discharge tube, and a protective tube made of quartz tube or the like is wrapped around the discharge tube, and both ends of the tube are fixed to a boss formed on the body 200. In the drawing, a portion visible to the outside of the body 200 is a boss, and a discharge tube and an end portion of a protective tube are coupled to the inside of the boss.

A plurality of ultraviolet reactors (100) are connected in parallel with each other in a state in which the respective bodies (200) are arranged side by side in the width direction. In other words, the sea water inflow pipe 300 and the sea water outflow pipe 400 of a plurality of ultraviolet reactor 200 are arranged in parallel with each other.

The central portion of the respective ultraviolet reactor 100 in the longitudinal direction of the seawater inlet pipe 300 is connected to a central portion extending vertically toward the seawater inlet pipe 300 or the seawater inlet pipe 650 of the neighboring ultraviolet reactor 100, And a connecting flange (not shown) for connecting the central distribution pipe of the neighboring ultraviolet reactor or the flange 652 of the sea water introduction pipe 650 to the end of each central distribution pipe 600 602 are formed.

Therefore, the seawater introduced through the seawater introduction pipe 650 is distributed to the seawater inflow pipe 300 of each ultraviolet reactor 100 through one common inflow passage, that is, the central distributor pipe 600.

Similarly, a central collecting pipe 700 extending vertically toward the adjacent ultraviolet reactor 100 or toward the seawater discharge line 750 is provided in the longitudinal middle portion of each of the ultraviolet reactor 100, And a connecting flange 702 is formed at the end of each central collecting pipe 700 for connecting the central collecting pipe of the neighboring ultraviolet reactor or the flange 752 of the sea water discharging pipe 750.

In this case, the second body 220 is integrated with the sea water inflow pipe 300, and the third body 230 is integrated with the sea water outflow pipe 400.

By combining the sea water inflow pipe 300 and the central distributor pipe 600 and the sea water outlet pipe 400 and the central collecting pipe 700 separately and assembling the body 200 with the body 200, Separation becomes easy. In addition, since the body 200, the sea water inflow pipe 300 and the sea water outflow pipe 400 can be separated from each other after the installation, the internal cleaning, maintenance, and replacement operations can be performed more easily.

Connection flanges 211 and 221 are formed at opposite ends of the divided first body 210 and the second body 220 and the end faces of the divided first body 210 and third body 230, And the coupling flanges 212 and 231 are formed so that the coupling flanges 211 and 221 facing each other are coupled to each other in a detachable state by fasteners (not shown) such as bolts and nuts.

Of course, although not shown in the drawings, a sealing member such as a gasket (including a liquid gasket) or a seal is interposed between the facing coupling flanges 211 and 221 (212 and 231).

In the ultraviolet reactor 100 shown in the figure, a flow stabilizing member 350 is disposed across the inlet of the body 200, which is a portion into which seawater flows from the seawater inflow pipe 300.

The flow stabilizing member 350 is composed of, for example, a perforated plate, so that the seawater entering the seawater inlet pipe 300 first collides against the perforated plate and is then passed through the inside of the body 200 Thereby stabilizing the intense flow of seawater.
