The ballast water treatment system 100 of third embodiment according to the present invention may include that ballast water treatment system above-mentioned is used Filter construction 10, fluid flow into pipe 60, fluid discharge pipe 70, the first bypass pipe 65, perfusion and enter pipe 90, backwashing water discharge Pipe 80, the second bypass pipe 75.

In the third embodiment of the present invention, it can be performed according to first embodiment or the ballast water treatment system of second embodiment The system urgent backwash process of filter construction.This is only just sharp in the case where needing quickly backwashed strainer 22 With, therefore by its aftermentioned detailed process.

As shown in Fig. 7 a and Fig. 7 b to Fig. 9 a and Fig. 9 b, fluid flows into pipe 60 and is fluidly coupled to ballast water treatment from external System filter construction 10, the fluid of filtered outside can flow into the supply of pipe 60 to ballast water treatment system by fluid System filter construction 10.

Ballast water treatment system filter construction 10 is applied the fluid at this point, can be formed in fluid inflow pipe 60 Liquid feed pump 210, the first valve 310 can be formed in the inflow entrance side of filter construction.

Fluid discharge pipe 70 enters pipe from the perfusion that ballast water treatment system filter construction 10 is connected to ballast water pot 90, the fluid filtered by ballast water treatment system filter construction 10 is mobile to ballast water pot side, or passes through The fluid of first bypass pipe 65 not filtered can be moved.

At this point, the outlet side of ballast water treatment system filter construction 10 is formed in fluid discharge pipe 70 Two valves 320.

First bypass pipe 65 is to flow into pipe 60 without ballast water treatment system filter construction 10 from fluid and connect It is connected to the pipe of fluid discharge pipe 70.At this point, third valve 330 is formed in the first bypass pipe 65, thus adjustable without ballast The fluid without filtering of water treatment system filter construction 10 is supplied to 70 side of fluid discharge pipe.

Backwashing water discharge pipe 80 is used in the case where ballast water treatment system is backwashed with filter construction 10 It is discharged, can connect from ballast water treatment system filter construction 10 to outside in backwashing water of the discharge comprising filter foreign matter It is connected to external fluid.

At this point, can be formed in backwashing water discharge pipe 80 for forming the anti-of acoustic pressure in back flushing nozzle in backwash Flushing pump 220.

Second bypass pipe 75 can be connected to backwashing water discharge pipe 80 from fluid discharge pipe 70.At this point, in the second bypass pipe 75 can be formed with the 5th valve 350.

Perfusion enters pipe 90 and is connected to ballast water pot from fluid discharge pipe 70, and can be formed with and flow into ballast water pot for adjusting Fluid the 4th valve 340.

That is, as shown in Figure 7a, ballast water treatment system 100 may include that pipe, a fluid that fluid from outside flows into are outside One pipe of portion's discharge and a pipe for flowing into ballast water pot.

Illustrate filter process, backwash process and urgent backwash process referring to Fig. 7 a and Fig. 7 a to Fig. 9 a and Fig. 9 b The movement of ballast water treatment system 100.

Firstly, Fig. 7 a be according to the circuit diagram of the filter process of the ballast water treatment system of the third embodiment of the present invention,

Fig. 7 b is to show the fluid of the inside of ballast water treatment system filter construction during the filtration process to flow Figure.

External fluid can be supplied to fluid by liquid feed pump 210 and flow into pipe 60.At this point, the first valve 310 is opened, But third valve 330 is closed.Therefore, supplying can be to ballast water treatment system filter to the external fluid that fluid flows into pipe 60 Structural body 10 is mobile.This is to flow into ballast water pot without the fluid of filtering in order to prevent.

Later, since the second valve 320 is opened, the fluid filtered by ballast water treatment system with filter construction 10 It can be mobile to ballast water pot side by fluid discharge pipe 70.At this point, without being backwashed, therefore backwashing pump 220 is inactive, And filtered flow graph is mobile without normal direction backwashing water discharge pipe 80.

As a result, as shown in Figure 7b, filtered fluid can enter the supply of pipe 90 extremely by the 4th valve 340 and perfusion being opened Ballast water pot.

Fig. 8 a is according to the circuit diagram of the backwash process of the ballast water treatment system of the third embodiment of the present invention, Fig. 8 b To show the figure that the fluid of the inside of ballast water treatment system filter construction during the backwash process flows.

As shown in Figure 8 b, external fluid can be supplied to body by liquid feed pump 210 and flow into pipe 60.At this point, with filtering Similarly, the first valve 310 is opened process, but third valve 330 is closed.Therefore, it supplies to fluid and flows into the external stream of pipe 60 Body can be mobile to ballast water treatment system filter construction 10.Since third valve 330 is closed, the fluid by filtering without Normal direction fluid discharge pipe 70 is mobile.

Later, the fluid filtered by ballast water treatment system filter construction 10 can be by the second open valve 320 and mobile to ballast water pot side by fluid discharge pipe 70.

It at the same time, can be by starting back flushing pump 220 come in backwashing water discharge pipe 80 and back flushing nozzle formation sound Pressure.At this point, the filtered fluid in part for being moved to fluid discharge pipe 70 and foreign matter one can be made by starting back flushing pump 220 Act the back flushing nozzle for back flowing back into the inside of filter house.

Also, control unit drives the motor of driving portion, thus the rotary shaft of the inside of filter house, back flushing nozzle and connection Pipe rotation, moreover, the foreign matter for filtering and being located at the inner peripheral surface of filter house by filter house can be inhaled by back flushing nozzle.

That is, substantially may include two kinds of process fluid flows in backwash process.In the same manner as filter process, filtered stream Body can be mobile to ballast water pot side, and at the same time, a part of filtered fluid can move together with foreign matter to back flushing nozzle It is dynamic.

At this point, the diameter of back flushing nozzle, connecting tube, backwashing water discharge pipe 80 is smaller than the straight of fluid discharge pipe 70 Diameter, therefore, the main flow direction of filtered fluid can be ballast water tank side.

Finally, Fig. 9 a is the electricity according to the urgent backwash process of the ballast water treatment system of the third embodiment of the present invention Lu Tu, Fig. 9 b are the fluid flowing for showing the inside of ballast water treatment system filter construction in urgent backwash process Figure.

The fluid of the outside supplied by liquid feed pump 210 can flow into the first valve 310 of the closing of pipe 60 by fluid It is mobile to the first bypass pipe 65.It therefore, can be by the first bypass pipe 65 without ballast water treatment without the fluid of filtering System is mobile to fluid discharge pipe 70 with filter construction 10.

It at the same time, can be by starting back flushing pump 220 come in backwashing water discharge pipe 80 and back flushing nozzle formation sound Pressure.Therefore, as shown in figure 9b, can be passed through by the fluid without filtering that the first bypass pipe 65 is moved to fluid discharge pipe 70 Fluid discharge pipe 70 is simultaneously mobile to connecting tube by back flushing nozzle.That is, from the flows outside of filter house to the inside of filter house And it can be mobile to backwashing water discharge pipe 80 by back flushing nozzle together with the foreign matter filtered from filter house.

Also, control unit drives the motor of driving portion, thus the rotary shaft of the inside of filter house, back flushing nozzle and connection Pipe rotation, moreover, can be inhaled by back flushing nozzle by the foreign matter that filter house filters.

At this point, since the 4th valve 340 is closed, by the first bypass pipe 65 be moved to fluid discharge pipe 70 without mistake A part of the fluid of filter can not flow into ballast water pot, but can be by the 5th valve 350 of the opening of the second bypass pipe 75 to recoil Wash water discharge pipe 80 is mobile.

That is, urgent backwash process substantially may include two kinds of process fluid flows also in the same manner as backwash process, that is, Come backwash filter portion and the flowing mobile to backwashing water discharge pipe 80 by the first bypass pipe 65 fluid discharge pipe 70 that drives in the wrong direction What the first bypass pipe 65 of process and process, fluid discharge pipe 70 and the second bypass pipe 75 were moved to backwashing water discharge pipe 80 Flow process.

At this point, as previously mentioned, if the diameter of back flushing nozzle, connecting tube, backwashing water discharge pipe 80 is discharged less than fluid Pipe 70, then the main flow direction of fluid can be the direction mobile to backwashing water discharge pipe 80 via the second bypass pipe 75.

As a result, urgent backwash process can largely be accumulated in the foreign matter filtered by filter house and need quickly to backwash it Be in emergency circumstances utilized.In the case, filtered fluid can flow into ballast water pot side.

As previously mentioned, in the third embodiment of the present invention, control unit may need the volume for urgent backwash process Outer control algolithm.

As previously mentioned, backwash process may depend on and be measured by first pressure sensor 62 and second pressure sensor 72 Differential pressure.At this point, can the case where the shorter than stipulated time is repeated in backwash process or even if all drive the first motor 42a and Second motor 42b come carry out backwash but measured differential pressure is more than proper range in the case that execute it is urgent backwashed Journey.

As an example, even if the sequential control by driving portion carry out backwash differential pressure still continue growing and reach In the case where 0.7bar, urgent backwash process can be performed.Also, the feelings more than the pressure of 0.8bar or more clock for 2 seconds It under condition, alarms, so as to all devices are out of service and execute urgent backwash process.

That is, in the exception by limiting the filtered 400 backwashed strainer 22 of ability of fluid net inflow ballast water tank In the case of, urgent backwash process can be performed.

More than, although the description of various embodiments of the present invention, but thought of the invention is not limited in this specification Middle revealed embodiment understands that the those skilled in the art of thought of the invention can be in identical thought range By the additional of structural element, change, the easy proposition other embodiments such as delete, increase, also, these should belong to it is of the invention Protection scope.
