Abstract

The present invention relates to a basket-type filtering system in which back washing is performed only by rotating movement of a back washing nozzle. In the basket-type filtering system, a hole-type back washing nozzle is formed in a body into and from which ballast water enters and exits. The basket-type filtering system is a filtering system which processes ballast water entering from a sea chest in a vessel. In the vessel, the sea water entering into the body having an inlet and an outlet through the sea chest is transferred to a ballast tank by a ballast pump, large particles and microorganisms are filtered out through primary filtering by an automatic back washing filter, secondary filtering is performed by a sterilization device, and sterilized ballast water is stored in the ballast tank. The back washing nozzle inside the basket-type filtering system does not perform vertical movement, but performs only rotating movement. Furthermore, the back washing nozzle is formed to be of a hole type, and thus back washing efficiency is improved. As described above, the basket-type filtering system, in which back washing is performed only by rotating movement of the back washing nozzle, according to the present invention is advantageous in that vertical movement is not performed and only rotating movement is performed and, thus, the system is simplified and efficiency of the filtering system is increased, and in that the back washing nozzle is formed to be of a hole type and, thus, sea water for back washing sucked via an individual hole enters at a flow velocity ranging from 5 to 20 m/sec and back washing efficiency of the filter is increased.

Description

Technical Field [0001] The present invention relates to a filter for a ballast water treatment apparatus having a backwash nozzle having improved backwashing performance,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basket-type filtering system in which a back-washing nozzle of a hole type is formed in a body through which a ball equilibrium water flows in. More specifically, The filter element is characterized in that the backwash nozzle of a hole type is only rotated in the body through which the ball equilibrium water flows in and does not move up and down, To a filter for a ship ballast water treatment apparatus.

With the rapid increase in trade and traffic volume using maritime, environmental destruction caused by foreign invasive species included in ship equilibrium has been constantly reported, and economic damage is reported to be more than 10 billion dollars annually worldwide . More than 5 billion tons of ballast water per year will move across the border and 7,000 kinds of marine life will be transferred together with harmful organisms such as daphnia, toxic algae, and cholera. In many waters, ecosystem disturbances are increasing at an alarming rate due to the influence of these invasive species, and the problem of these invasive species is expected to continue due to increased maritime trade volume.

In 1988, Canada and Australia experienced problems with the emergence of harmful species in their waters, and for the first time posed a question to the Maritime Environmental Protection Committee of the International Maritime Organization, the IMO General Assembly in 1993 urged it to prevent the introduction of an aquatic organism In 1997, the 20th General Assembly of the IMO adopted for the control and management of ship ballast water to minimize the transfer of harmful aquatic organisms and pathogens. As a result of these efforts, the BWM Convention (2004) was adopted at the Hong Kong diplomatic conference in 2004 and discussions and measures for ship ballast water treatment and management are being carried out internationally.

Conventional ship equilibrium water treatment has been carried out in accordance with the Convention for the Management of Ballast Water by using filters, ultraviolet irradiation apparatus, electrolysis apparatus designed to satisfy ship ballast water treatment regulations, And the living organisms contained in it. Ship ballast water treatment technology takes into account various seawater conditions such as turbidity, temperature, and salinity, to ensure adequate performance to meet the processing requirements of the Management Guidelines of the [Ballast Water Management Convention] .

Hereinafter, a filter for a conventional ship ballast water treatment apparatus will be briefly described.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a system for a conventional ballast water treatment apparatus. FIG.

2 is a schematic diagram of an automatic backwashing filter system for a conventional ballast water treatment apparatus.

3 is a front view of a filter for a ship ballast water treatment apparatus according to the present invention and its interior.

1, the overall system of the filter for a conventional marine ballast water treatment apparatus is such that the seawater introduced through the seed chest 100 from the ship is sent to the ballast tank 700 by the ballast pump 200, A ballast water treatment system is a system in which 50 or more large particles and microorganisms are usually filtered by a filter, and sterilized by a sterilization treatment device and stored in a ballast tank.

As shown in FIGS. 2 and 3, generally, the filter for a ship ballast water treatment apparatus is provided with an inlet and an outlet so that the ballast water can flow in and out, and one or a plurality of A filter element 330 is provided. Here, the filter element 330 forms fine pores of about 40 to 50 on the surface thereof, thereby filtering the organisms or solids contained in the equilibrium water of the ship. Therefore, the ship ballast water is filtered through the filter element 330 and then filtered through the fine voids to filter the organisms or solid matter.

In this filtering process, foreign matter is accumulated inside the filter element 330, and the filter element 330 is subjected to backwashing to prevent the clogging of the air gap. Backwashing is automatically performed by the differential pressure between the pre-set filter PT1 (Pressure Transmitter) 310 and the downstream pressure transmitter PT2 320. In addition, And spacing. When the backwashing operation is performed, a separate drain pipe is connected to the lower end of the backwash pipe so that the backwash pipe is exposed to the atmospheric pressure, and the ballast water filtered by the backwash nozzle 340 flows backward by the pressure difference between the pressure inside the filter and the atmospheric pressure So as to clean the pores of the filter element 330. The backwashing valve 800 of FIG. 2 is opened when the control valve 400 of FIG. 1 is closed to a certain angle. The backwashing valve 800 of FIG. 2 and the geared motor (GM) The backwash pump 900 is operated and the foreign matter accumulated inside the filter element 330 of FIG. 3 is sucked by the backwash nozzle 340 and discharged to the backwash line. The filter element 330 of the prior art is a basket type. In general, the basket type filter is backwashed while the backwash nozzle is rotating and moving up and down.

4 is a view showing an example of a slit type backwash nozzle of a conventional basket type filter.

5 is a graph showing a result of a performance test on the shape of a slit type backwash nozzle according to the prior art;

As shown in FIG. 4, when the backwash nozzle has a slit-type backwash nozzle 360 having a vertical movement and a rotational movement, the flow rate of the backwash water sucked into the slit When a large amount of solid matter flows into the filter element 330, the backwashing of the filter is not properly performed and the filter element 330 is frequently clogged. This is also shown in the test results of FIG. Looking back at the graph, we can see backwashing, but the differential pressure continues to rise and the filter clogs up.
