Description

Apparatus for sample monitoring of ballast water for a ship}

The present invention extracts the ballast water sample from the main supply pipe for supplying the ballast water to the ballast tank of the ship and supplies the sample to the sample measuring device installed on the deck to measure various pollutants and microorganisms contained in the ballast water. The present invention relates to preventing the inspection apparatus from being exposed to weather conditions that are frequently changed during the operation of the ship or a poor external environment, and effectively preventing the backflow of the ballast along the discharge path of the sample, thereby preventing failure or malfunction of the inspection apparatus. The present invention relates to a sampling inspection apparatus for ship ballast water.

In general, ballast water is installed on both sides of the bottom of the ship to prevent the ship from being unbalanced when the ship is operated when the ship is unloaded from the ship or when the amount of cargo loaded on the ship is very small. It refers to the buoyancy adjustment freshwater or seawater filled inside the ballast tank.

Such ballast water contains various microorganisms such as pathogenic bacteria and plankton contained in freshwater or seawater filled with ballast water. Therefore, if it is discharged into the water of another region without any treatment, serious marine pollution And the destruction of ecosystems.

Based on this situation, in 1996, in the United States, the national invasive species law was enacted, requiring the management and control of the ballast water by stipulating the exotic species as the intruder. In Australia, the quarantine law was amended to import the ballast water As well as direct quarantine.

On the other hand, the International Maritime Organization (IMO) concluded an international agreement in February 2004, and from 2009, the ship was required to install the necessary equipment for the sterilization and purification treatment of ballast water sequentially. In case of violation, Of the total number of vessels.

Accordingly, various techniques for treating ship ballast water have recently been developed, and a representative example thereof is sterilization and purification treatment of ballast water using ozone (O ₃ : 0 ₃ ). In addition, Ballast water purifiers have been developed or are under development.

The ballast water purification device mounted on the vessel as described above, after receiving the certificate through the land test and the shipboard test in accordance with the standards of the International Maritime Organization (IMO), the certificate is carried on the ship, the ballast water purification device Sampling inspection devices have been installed and used on board ships to ensure that the ballast water treated in accordance with the system can meet the emission standards at any time.

The buffer chamber 12 is installed to adjust the flow rate and flow rate of the sample ballast water flowing into the sample measuring unit 11 to an appropriate level, and the overflow to return the excess ballast water to the ballast tank (1) The flow line 15 is installed at the upper end side, and the main supply pipe 3 has a supply pump 3a for supplying seawater from the sea-chest to the ballast tank 1 and a flow meter 3b. It is provided together, and the supply line 6 is provided with a strainer 6a, preferably a Y-strainer, for removing suspended matters contained in the ballast water.

In the drawing, two sampling pipes 4 are shown, which are arranged in two rows with a plurality of ballast tanks 1 arranged on the left and right sides of the ship, for supplying ballast water to each ballast tank 1. This is because the main supply pipe (3) is also divided into two places, the sample measuring instrument (11) forming a sampling pump (5), supply line (6) and sampling inspection apparatus (10) in accordance with the number of such sampling pipe (4) and Two buffer chambers 12 are also provided.

In addition, each sampling pump 5 for supplying a sample of ballast water to the sample measuring unit 11 is installed together with the drain pump 8 inside the pump casing 7 of the ballast tank 1. (8) is connected to the drain pipe (8a) for discharging the ballast water introduced into the pump casing (7), while operating the drain pump (8) by detecting the water level of the ballast water introduced into the pump casing (7) Level switch 9 is connected.

Therefore, by extracting a sample of the ballast water from the main supply pipe (3) and sending it to the sample measuring instrument (11) to measure various contaminants or microorganisms contained in the sample, the failure or malfunction of the sample measuring instrument (11) may occur. In this case, the valve mechanism V installed at the inlet of the measuring instrument is locked, and the three-way valve 16 installed at the injection line 13 of the measuring instrument is operated to send a sample to the preliminary measuring instrument 11a.

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

As shown in FIGS. 2 to 4, the sampling inspection apparatus 10 for ship ballast water according to the present invention has a sampling pump 5 in the sampling pipe 4 branched from the main supply pipe 3 of the ballast water. And a supply line 6 extending from the sampling pump 5 to the upper side of the deck 2 to be connected to the buffer chamber 12 and passing through the three-way valve 16 from the buffer chamber 12. An extending injection line 13 is installed in connection with the inlet of the sample meter 11.

In addition, the auxiliary injection line (13a) is further extended from the three-way valve 16 is connected to the inlet of the preliminary measuring device (11a), and the sample of the sample connected to the outlet of the sample measuring device (11) and the preliminary measuring device (11a) The recovery line 14, 14a extends to the deck 2 side, while the overflow line 15 of the sample connected to the upper end side of the buffer chamber 12 extends to the deck 2 side. And the function of each component is the same as that described in the prior art.

As the components corresponding to the first essential part of the present invention, the sample measuring unit 11, the preliminary measuring unit 11a, and the buffer chamber 12 include an injection line 13 and an auxiliary injection line (3). 13a) is inserted into and installed inside the device casing 20 disposed on the upper part of the deck 2, and the recovery line of the sample measuring device 11 and the preliminary measuring device 11a is installed at the bottom of the device casing 20. 14) 14a and a water chamber 17 as a buffer tank to which the overflow line 15 of the buffer chamber 12 is connected are installed.

3 and 4, the sample measuring unit 11, the preliminary measuring unit 11a, and the buffer chamber 12 are mounted on the mounting frame 22 provided at the inner center of the device casing 20. It is fixedly installed, and a carrying ring 20a is provided on the upper side of the device casing 20 for the convenience of carrying and installing the inspection device 10, and supports the inspection device 10 on the lower side of the device casing 20. Meanwhile, a framed lower frame 23 is provided to secure an installation space of the water chamber 17.

Therefore, the supply line 6 extending from the sampling pump 5 is inserted into the device casing 10 from the deck 2 via the bottom of the device casing 20 and then connected to the buffer chamber 12. , The return lines 14 and 14a of the sample measuring instrument 11 and the preliminary measuring instrument 11a and the overflow line 15 of the buffer chamber 12 are also connected to the water chamber 17 inside the device casing 20. It is installed, and the final discharge pipe (17a) of the sample from the water chamber 17 is extended and connected to the ballast tank (1).

In FIG. 3, a part of the auxiliary injection line 13a and a part of the recovery line 14 and 14a which connect the sample measuring device 11 and the preliminary measuring device 11a are not shown in the sample pipe line to avoid the complexity of the drawing. However, the overall structure and arrangement of the sample pipe line for the sample is to be understood that it can be sufficiently understood using the pipe diagram shown in FIG.

And, the internal structure of the device casing 20 shown in Figure 3 is one representative embodiment that can be applied to the present invention, it does not mean that it is limited to the structure of the form shown in Figure 3, and the water chamber 17 and As shown in the drawing, two discharge pipes 17a connecting the ballast tanks 1 may also be installed, or two discharge pipes 17a may be integrated into one pipe.

Therefore, the space heater 18, which is miniaturized and lightened, is applied to be used in a narrow inner space of the device casing 20, but has no external mechanical shock, vibration, or electrical hazard. It is most preferable to use a product that is made of a 304 material or the like, and is provided with an automatic temperature control function and an overheat prevention function, and of course, other types of heaters may be applied in addition to the space heater 18.

When the space heater 18 is installed inside the device casing 20 as described above, it is possible to prevent the inoperability of the sample measuring instrument 11 generated under low temperature conditions or freezing or freezing of the sample pipe line. This ensures the normal operation of the sampling inspection apparatus 10 even under conditions where the external temperature is very low, thereby ensuring a wide range of usability of the inspection apparatus 10.
