Summary of the invention
In above-mentioned known Ballast Water manufacturing installation, the filter pore size of filtering usefulness is bigger, is about 50 μ m.The aperture is less then stop up easily if this is, for fear of this problem, needs the filter area of increasing filter, is unfavorable for being equipped on the ship so can make the device maximization.So the planktonic organism below the 50 μ m can be handled to clean plate the seawater winding-up through high speed and high pressure with the planktonic cavitation of fragmentation or through dropping into reagent.
But, because the processing of cavitation is with high speed and high pressure winding-up seawater, not only need sizable power, and cause the minimizing of planktonic organism number to surpass necessary amount, might influence the marine ecosystems that Ballast Water loads side.In addition, under the planktonic situation of processing such as use reagent, need a large amount of reagent, cause each disposal cost to uprise.
The present invention accomplishes in view of the above problems; Its purpose is to provide a kind of microparticle of removing; And can import expense and the filter element of keeping administrative expenses the reduction initial stage; And a kind ofly under not injuring the planktonic situation of surviving in the seawater as far as possible, can it not flow back to outboard, and can reach the Ballast Water manufacturing installation of miniaturization reduction process cost.
In order to reach above-mentioned purpose, filter element of the present invention is made up of filter material and the framework of taking in this filter material, and this framework comprises: former water supply port, and Jiang Yuanshui is supplied to this filter material; The filtered water stream outlet; The fluid supply port, the fluid that back washing is used is supplied to this filter material; Outlet, will to this filter material carry out after the back washing fluid and should former water discharge, wherein, this filter material is the deep filter of aperture 1～25 μ m.But fluid using gases or liquid that back washing is used are preferably gas, more preferably inactive gas such as air, nitrogen.
The aperture is done as giving a definition.In water, add the particle comprise certain diameter, preferably in water, add spherical polystyrol or the bead of 10000/L, with this liquid in 25 ℃, 1.0m
3Under the condition of/hr; Through deep filter (external diameter 60mm, internal diameter 30mm, length 250mm); Pass the amounts of particles of deep filter with the measurement of optical counting device, the resulting capture rate of amounts of particles (R%) that the difference of the amounts of particles that exists in the liquid before and after the water flowing exists in the liquid before divided by water flowing is measured a plurality of particles, according to its measured value in following approximate expression (1); Obtain the value of the diameter (S) that R equals 80 o'clock particles, it is made as the aperture.
R＝100/(1-m×exp[-a×log(S)]) (1)
M, a are the constants that determines according to the characteristic of deep filter here.
For example, be under the situation of 1 μ m at particle diameter, through above-mentioned condition, can make and add spherical polystyrol microparticle (10000/L) liquid flow through deep filter (external diameter 60mm, internal diameter 30mm, length 250mm) and measure.
Constitute according to this,, not only can remove small-sized floating material, and compare, can suppress the importing expense at initial stage with the situation of using surface filter because filter material has used the deep bed filter of aperture 1～25 μ m.In addition, can recover the strainability of filter material,, can suppress to keep administrative expenses so reduce the frequency of filter material replacement through carrying out countercurrent washing.
In the present invention, preferably this fluid supply port is identical with this filtered water stream outlet.According to this formation, universal fluid supply port and filtered water stream outlet can be simplified formation.
In the present invention, this filter material preferably fixes the two ends of a plurality of filters with fixed head and is integrally formed.According to this formation, through making up a plurality of deep filters, filter area is increased, be integrally formed and make a plurality of deep filters form a unit combination, make the replacement filter material become easy.
In the present invention, also can tilt towards the outlet of this filtered water stream and towards the oblique below mode at 20～70 ° of inclinations angle of this filter material is provided with.Constitute according to this, because the opposition side of the filtered water stream of filter element outlet uprises, for example, when carrying out raw water filtration again after the gas back washing, because the gas in the framework can discharge from this opposition side easily, so air is sneaked into the possibility minimizing of filtered water.In addition, if the inclination angle is excessive, then the size of filter element above-below direction becomes big, when taking off maintenance, and the space of taking out the required broad of filter material from the filter element top, if the inclination angle is too small, then the fluid in the filter element is difficult to flow out.
In the present invention, this filter material also can be provided with towards the outlet of this filtered water stream and towards the tilt mode at 20～70 ° of inclinations angle of oblique upper.According to this formation; The openend that is positioned at the deep filter of filtered water taking-up side forms opening towards oblique upper; And near the air the blind end of the deep filter of lower position can be discharged from openend; Therefore can prevent that air from residuing in the deep filter, can utilize the integral body of deep filter, filter effectively.
In the present invention, preferably this outlet is arranged at this former water supply port top.According to this formation, carry out back washing when starting first or with gas after, Jiang Yuanshui is supplied in the filter element, carries out so-called in the unit " exhaust operation ", this moment can successfully the gas in the filter element be discharged.

Drain passageway is connected to the outlet of this filter element, will discharge towards boats and ships are outside to the former water of fluid in filter element that this filter material has been cleaned.
According to this formation; The aperture that forms the deep filter of filter material is 1～25 μ m; Therefore can make most of planktonic organism survival and, not only can not destroy the marine ecosystems that Ballast Water loads side, and not need as known with its seizure and discharge outboard; Carry out cavitation or drop into reagent being used for handling planktonic organism, so can reduce the electric weight that power consumes or the use amount of reagent.Its result can constitute the cheap system of miniaturization and disposal cost.In addition, because the back washing filter material reuses so can recover the strainability of this filter material, can further cut down disposal cost.
In Ballast Water manufacturing installation of the present invention, preferably further comprise ultraviolet irradiation unit, it carries out irradiation ultraviolet radiation to the filtered water after filtering through this filter element.Handle under the planktonic situation at irradiation ultraviolet radiation,,, then be necessary to increase the quantity that is provided with of ultraviolet lamp, cause the maximization of device and the increase of consumes electric power as its countermeasure because the particle that swims in the seawater etc. can cause uitraviolet intensity to reduce.According to this formation; Through deep filter, remove the most of planktonic organism in the above-mentioned seawater earlier, therefore can suppress uitraviolet intensity and reduce; Reduce the ultraviolet irradiation amount also can, so can reach the miniaturization of device and the minimizing of consumes electric power through the radical that is provided with that for example reduces ultraviolet lamp.
State in the use under the situation of ultraviolet irradiation unit, preferably this filter material is the deep filter of aperture 1～10 μ m.The bigger ultraviolet energy that just need be a large amount of more of the planktonic organism that generally will eliminate, the eliminating bacteria class of comparing, wanting to eliminate the planktonic organism class then needs very a large amount of irradiation energies.Therefore, as much as possible the planktonic organism class is removed extremely important carrying out ultraviolet pre-irradiation for the miniaturization of ultraviolet irradiation unit and the minimizing of consumes electric power etc.The filter element of this structure almost can all be removed the macroplankton more than the 50 μ m, and microplankton that can most 10 μ m are above is removed.In addition, be not planktonic organism, even can the particle that swim (SS composition) of size about 1 μ m be removed yet.Thus, can reduce the turbidity in the former water significantly, and increase substantially transparency.Its result when carrying out the ultraviolet ray irradiation, can promote the transmission of ultraviolet ray in former water significantly, can reduce the ultraviolet irradiation amount through improving ultraviolet transmission, so can reach the miniaturization of unit and reduce consumes electric power.In addition, can reduce the dirt that is attached to the ultraviolet lamp surface significantly, so can improve the maintainability of unit.
In Ballast Water manufacturing installation of the present invention, preferably further comprise chemical treatment, to dropping into solid calcium hypochlorite in the filtered water after filtering through this filter element.Dropping into chlorine or hypochlorous acid reagent such as receives and produces hypochlorous acid to handle planktonic situation; Not only need use a large amount of reagent to eliminate planktonic organism; When Ballast Water is expelled to the ocean, also need drop into reducing agents such as sodium thiosulfate neutralizes; Not only can increase burden, each disposal cost is improved the environment aspect.According to this formation; Because the aperture of deep filter is 1～25 μ m; So most of planktonic organism can be hunted down under the state of survival and discharge outboard; The a large amount of reagent of input that need not as all the time are handled planktonic organism, and the use amount that can reduce calcium hypochlorite thus gets final product, in also need not when Ballast Water is drained back to seawater to carry out with reducing agent and operation.Its result can constitute the cheap system of miniaturization and disposal cost.
Use the situation of chemical treatment, preferably this chemical treatment will let the concentrate that takes out after the solid calcium hypochlorite dissolving of this container drop in this filtered water, carry out microbiological treatment through the hypochlorous acid that produces, and this container has been taken in solid calcium hypochlorite.Constitute according to this, owing to used the calcium hypochlorite of solid, they are different with liquid reagent, and are on land or the sea can be transported easily and economy comparatively, comparatively loose about the regulation limitations of transportation aspect.In addition, the fusing point of calcium hypochlorite is higher, so in the hull that becomes high temperature easily, preserve than being easier to.Moreover owing to be solid, its volume is little, only needs less preservation place to get final product, and also can make device self miniaturization simultaneously, and is comparatively favourable for situation about being arranged in the limited hull in space.
Use the situation of chemical treatment; Preferred this chemical treatment is for to be dissolved to this solid calcium hypochlorite: from a part of filtered water that the water delivery forehearth limb that supplies with this filtered water takes out; It is confluxed in this water delivery path; Wherein between this bifurcation and this river outlet throttle mechanism is set, in order to the flow of the filtered water that reduces this water delivery path.Constitute according to this, from bifurcation solid calcium hypochlorite is supplied to and reduces the filtered water that flow causes being left, therefore need not to be provided with feed mechanisms such as dedicated pump, not only simplified structure also can reduce necessary power consumption.The pony pump that low capacity also can be set replaces this throttle mechanism, from this water delivery path, the filtered water of a part is taken out.
Use the situation of chemical treatment, preferably this solid calcium hypochlorite is accommodated in the closed container.Constitute according to this, the smell that can suppress chlorine leaks in the hull.In addition, during the exchange solid calcium hypochlorite, can exchange, avoid calcium hypochlorite directly to contact with human body or the interior air of hull together with container.
Filtered water manufacturing approach of the present invention; It utilizes the deep filter of aperture 1～25 μ m to filter former water to make the method for filtered water; Comprising the back washing operation: former water is supplied to this deep filter on one side; Supply with fluid to deep filter from the filtered water side on one side, and this fluid is discharged with this former water.
Constitute according to this, reuse, therefore can suppress to keep the expense of management through carrying out the strainability that back washing can recover filter material.In addition, carry out also often former water being supplied to filter element in the back washing, thus back washing with fluid can adverse current to former water supply side, can successfully carry out draining.In addition, with only to catch the filter on the surface that is filtered material through filter surfaces different, deep bed filter can be caught through filter thickness direction integral body and is filtered material, so its seizure amount is more, can not cause the long-time obstruction of filter.
Ballast Water manufacturing approach of the present invention, the Ballast Water manufacturing approach that it uses Ballast Water manufacturing installation of the present invention comprises following operation:

The specific embodiment
Below, with reference to accompanying drawing the preferred embodiment of the invention is described.Fig. 1 is the roughly system diagram of ballast for cruising water making device with filter element of the present invention's the 1st example.Ballast Water manufacturing installation 1 is arranged in the boats and ships S, and it has puts into the ballast pump 2 of boats and ships S and the filter element 4 that the former water RW that puts into boats and ships is filtered with former water RW.Filter element 4 is connected with: former water passage 5, supply with former water RW through ballast pump 2; Water delivery path 8, the filtered water FW of the unit of inherent filtration in the future 4 is supplied to the ballasting jar 6 that is arranged in the boats and ships S; Drain passageway 14, with the former water RW in the filter element 4 with after the compressed air A that states discharge towards boats and ships are outside.And water delivery path 8 is connected with the gas supply passageway 12 that compressed air A is supplied to filter element 4.Thus; With respect to the existing Ballast Water manufacturing installation that carries on boats and ships S; Change its filter element into filter element 4 of the present invention, and gas supply passageway 12 is connected to existing water delivery path, just can apply the present invention to existing Ballast Water manufacturing installation easily.
Each path 5,8,12,14 is formed by pipe arrangement.Take in the deep filter 10 of the material that forms filter membrane in the tubular cabinet 9 of filter element 4.In this example, though ballast pump 2 carries on boats and ships, it also can be arranged on the boats and ships outside, for example, also can be arranged on the harbour.
In former water passage 5, connect the 1st automatic switch valve MV1 that brings into play function as the adjustment valve of raw water flow, and between the 1st automatic switch valve MV1 and filter element 4 of former water passage 5, promptly the primary side of filter element 4 is provided with pressure sensor P1 No. one time.In water delivery path 8, connect the 2nd automatic switch valve MV2 that brings into play function as the induction valve of filtered water FW, and between the 2nd automatic switch valve MV2 and filter element 4 of water delivery path 8, promptly the secondary side of filter element 4 is provided with secondary pressure sensor P2.Moreover ballasting jar 6 upstream sides of water delivery path 8 are provided with blender 26, can stir the sterilization that drops into from reagent trough 28 with reagent and filtered water FW through this blender 26.The reagent that drops into is hypochlorous acid salt, peroxide for example.In addition, in order to make the processing water of the benchmark that meets Ballast Management treaty regulation, also can use other known method for disinfection to substitute and drop into compositions and methods.Object lesson has method that makes its method that contacts with ozone, irradiation ultraviolet radiation etc.
In gas supply passageway 12, connect the 3rd automatic switch valve MV3 that brings into play function as compressed air importing valve, in drain passageway 14, connect the 4th automatic switch valve MV4 that brings into play function as draining valve.The air compressor that does not show in the one end connection layout of this gas supply passageway 12, and the other end connects the secondary side of filter element 4 bottoms.In addition, the other end of gas supply passageway 12 also can connect water delivery path 8 filter element 4 near, more specifically, also can be connected between filter element 4 and the secondary pressure sensor P2.The driving of ballast pump 2 and the 1st～4 automatic switch valve MV1～MV4 is by controller 30 controls.In addition, the output of pressure sensor P1 and secondary pressure sensor P2 is by controller 30 inputs.
Air compressor also can use for other purposes and be equipped on the equipment on the boats and ships, also can be provided with specially.In addition, each automatic switch valve MV1～MV4 can use pneumatic operated valve, motor-driven valve, magnetic valve or not use the hand-operated valve etc. of controller.
Shown in Figure 2 like the profile of filter element 4; One end wall 9a of framework 9 downsides of the filter element 4 that tilts is provided with filtered water stream outlet 16; Near the end wall 9a among the peripheral wall 9b of the framework 9 of filter element 4 place, bottom is provided with former water supply port 18; Above former water supply port 18, near the place, top another end wall 9c among the framework 9 peripheral wall 9b is provided with outlet 22.
This former water passage 5 connects former water supply port 18, and water delivery path 8 connects filtered water stream outlet 16, and drain passageway 14 connects outlet 22.Because filtered water stream outlet 16 connects gas supply passageway 12; Filtered water stream outlet 16 is held concurrently and is the gas supply port 24 of the compressed air A of filter element 4, is the lower position of the outlet of compressed air A and former water RW export mouth 22 so gas supply port 24 is arranged to liken to.Thus, utilize the air lift effect of the pressure of compressed air A, promptly utilize air that the former water RW in the drain passageway 14 is up pushed away, discharge former water RW, so can former water RW and compressed air A successfully be discharged.Former water supply port 18 and outlet 22 are arranged at the primary side of deep filter 10, and filtered water stream outlet 16 is arranged at secondary side.
The aperture of filter membrane is 1～25 μ m, more preferably 1～10 μ m.Meeting cause clogging when the aperture is too small, it is big that the pressure loss becomes.Because the aperture is excessive, and less planktonic organism is passed through,, make the Ballast Water manufacturing expense uprise for reducing the necessary extra use air pocket generating mechanism of this problem etc.
Secondly, use Fig. 1 and Fig. 3, the method for operation of relevant Ballast Water device is described, that is, and the Ballast Water manufacturing approach of the filter element of this example.As shown in Figure 3, the method for operation of Ballast Water manufacturing installation is by forming as the deairing step that filters preparatory process, the 1st conversion operation, filtration operation, the 2nd conversion, the 3rd conversion and back washing operation.
Start button (not shown) to being arranged on the controller 30 is operated, and makes 1 action of Ballast Water manufacturing installation, and then at first ballast pump 2 starts, and opens the 1st automatic switch valve MV1 and the 4th automatic switch valve MV4 and gets into deairing step.In deairing step; Close the 2nd automatic switch valve MV2 and the 3rd automatic switch valve MV3; 6 supply filtered water FW supply with under the state of compressed air A towards deep filter 10 with stopping stopping from deep filter 10 towards the ballasting jar; Via filter element 4 former water RW is expelled to drain passageway 14, and discharges, carry out the exhaust of former water passage 5 and filter element 4 thus towards outboard.
Then, open the 2nd automatic switch valve MV2, get into the 1st conversion operation.The 1st conversion operation is supplied with filtered water FW to water delivery path 8 stopping under the state of deep filter 10 supply compressed air A, supplying with former water RW respectively to drain passageway 14 via filter element 4.
, close 4th automatic switch valve MV4, get into and filter operation thereafter.Filter operation stopping from deep filter 10 drainings, stopping to supply with under the compressed-air actuated state, former water RW is supplied to filter element 4, filtered water FW is delivered to water delivery path 8 towards deep filter 10.At this moment, former water RW flows into hollow bulb 11 from deep filter 10 outsides via the filter membrane of deep filter 10, and the foreign matter of removing thus among the former water RW filters.Filtered water FW supplies with towards ballasting jar 6 through water delivery path 8.
Secondly, open the 4th automatic switch valve MV4, get into the 2nd conversion operation.The 2nd conversion operation is stopping under the state of deep filter 10 supply compressed air A, supplying with former water RW to filter element 4, and filtered water FW flow to water delivery path 8 thus, and former water RW flow to drain passageway 14.
Then, close the 2nd automatic switch valve MV2, get into the 3rd conversion operation.The 3rd conversion operation is supplied with filtered water FW and is stopped to supply with under the state of compressed air A towards depth-type filtration gas 10 stopping from deep filter 10 towards the ballasting jar 6, and former water RW flow to drain passageway 14.So, through stopping to supply with filtered water FW, prepare beginning thus and supply with compressed air A towards the opposite direction of the filtered water FW flow direction of follow-up back washing operation from deep filter 10.
Secondly, under the state of closing the 2nd automatic switch valve MV2, open the 3rd automatic switch valve MV3, get into the back washing operation.The back washing operation is stopping under the state of ballasting jar 6 supply filtered water FW, on one side former water RW is supplied to filter element 4, supplying with compressed air A towards the hollow bulb 11 of deep filter 10 on one side, this compressed air A flow to drain passageway 14 with former water RW.Thus, compressed air A and the opposite direction of filtering operation be via deep filter 10, be attached on the deep filter 10 foreign matter be piled up in foreign matters in the framework 9 toward filter element 4 outer derivation, and discharge the outside from drain passageway 14 toward boats and ships S.
In case accomplish the back washing operation, then close the 3rd automatic switch valve MV3, turn back to deairing step.Repeat this circulation then.The duration of deairing step can be carried out variable setting through time-limit attachments such as timers.The time that sets is different with the scale of the equipment of processing, for example about several seconds to 1 minute.1st, the 2nd and the 3rd conversion operation is the very short time, for example about several seconds, also can carry out variable setting through time-limit attachments such as timers.So, before getting into filtration operation and back washing operation,, can avoid producing in the path pressure oscillation rapidly via the 1st, the 2nd and the 3rd conversion operation.The time of filtering operation and back washing operation, and different, for example about 10 minutes, it also can carry out variable setting through time-limit attachments such as timers according to the scale of the water quality of former water and equipment.Also can work as pressure sensor P1 and secondary pressure sensor P2 pressure differential Δ P (=P1-P2) greater than the time point of setting, switch to the 2nd conversion operation from filtering operation.
In filtering operation, controller 30 is monitor pressures difference Δ P often, when pressure differential Δ P surpasses alarm value H1, for example can send alarm such as buzzer and arouse attention.Water treatment facilities 1 still remains in operation at the moment.And then, when pressure differential Δ P increases and surpasses when promptly stopping to be worth H2, for example sending the tinkle of bells alarm, water treatment facilities 1 promptly stops.Particularly, controller 30 stops ballast pump 2, closes all automatic switch valve MV1～4.
Pressure rapidly changes and change in flow not only can be damaged to planktonic organism; Also can produce water hammer effect (water hammer) at ballast pump 2, each automatic switch valve MV1～4 and each path 5,8,12,14; As the method for operation of Fig. 3; Ballast pump 2 turns round often and does not stop from ballast pump 2 supplying with former water RW, and regulates each automatic switch valve MV1～4 switch opportunity, therefore can turn round reposefully.In addition, on one side owing to flow former water RW and carry out back washing, thus the air pressure draining successfully of spue pressure and compressed air A that not only can be through ballast pump 2, and need not extra other draining pump and the drainage piping of being provided with, ability simplification system.
In this constitutes, be 1～25 μ m owing to form the aperture of the filter membrane of deep filter 10, so in the pressure loss that the inhibition filter blocks causes; Can make most of planktonic organism survival, and it is caught, not only can not destroy the marine ecosystems that Ballast Water loads side; Also need not as known; Carry out cavitation and drop into reagent, handle planktonic organism, the consumes electric power amount of power or the use amount of reagent have tailed off.Its result can constitute the Ballast Water manufacturing installation of the cheap and miniaturization of disposal cost.In addition, because back washing deep filter 10, can recover the filterability of deep filter 10 and use, can further reduce disposal cost.Moreover, owing to use cheap deep filter 10,, can the control initial stage import expense so compare the surface filter of catching foreign matter with the such filter surfaces of flat film.
Because gas supply port 24 is same with filtered water stream outlet 16, so gas supply port 24 and filtered water stream are exported 16 generalizations, can simplify formation.
Moreover; Since filter element 4 with filtered water stream outlet 16 down square neck tiltedly be provided with; So the opposition side position of the filtered water stream of filter element 4 outlet 16 uprises; After the gas back washing, carry out former water RW when filtering, the air A in the filter element 4 can discharge easily, reduce the situation that air is sneaked into filtered water FW.In addition; When excessive, because the size of filter element 4 above-below directions becomes big, so taking off etc. when keeping in repair with respect to the inclined angle alpha of this horizontal direction; In order to take out from filter element 4 tops with deep filter 10; Need bigger space, when too small, the air A in the filter element 4 then is difficult to discharge.Therefore, this inclined angle alpha is preferably 20～70 °.
Because discharge outlet 22 is arranged on more top of former water supply port 18, so in order to filter running when beginning to supply with the initial stage of former water, when perhaps beginning to supply with former water after the back washing again and discharging the air in the filter element 4 thus, the air A in the filter element 4 are discharged smoothly.
Moreover as shown in Figure 3 according to above-mentioned method of operation, in the system works running, ballast pump 2 is turning round always, that is, owing to supply with former water RW towards filter element 4 always, can avoid causing pressure variation rapidly in the path, and prevent the generation of impact of water hammer.In addition, in the back washing operation, also supply with former water RW,, can make not adverse current in former water passage 5 of compressed air A, and discharge smoothly with former water current through the supply pressure of compressed air A and the supply pressure of former water RW towards filter element 4.
In addition, with only to catch the surface filter that is filtered material at filter surfaces different, deep filter is filtered material because the whole thickness direction of filter can both be caught, so quantity of the catch is big, and can not cause the filter long-term blockage.
Use the deep filter 10 of this example to carry out confirmatory experiment.Former water is seawater, and the supply pressure of former water and flow are respectively 0.03MPa, 0.037m
3/ min.The fluid that back washing is used uses compressed air, and compressed-air actuated supply pressure and flow are respectively 0.13MPa, 0.4Nm
3/ min.Employed deep filter specification is length 25cm, aperture 1 μ m, 25 μ m.In addition, the axle center of deep filter is horizontal by the miter angle tilted configuration.
Checking 1: the initial stage pressure loss
In the deep filter of aperture 0.5 μ m, 1 μ m and 25 μ m when table 1 is presented at 25 ℃ of former coolant-temperature gages, deep filter primary side when supplying with former water and the pressure differential between secondary side.Fig. 4 is the supply flow rate of the former water of demonstration and the relation of the pressure loss.Can be known that by table 1 and Fig. 4 the pressure loss in the deep filter of 1 μ m and 25 μ m is less, but the pressure loss in the deep filter of 0.5 μ m is very big, nearly all former water all can not flow.Therefore, the aperture of deep filter is preferably more than the 1 μ m.
[table 1]
| The aperture | The pressure loss |
| 0.5μm | 0.03MPa |
| 1μm | 0.017MPa |
| 25μm | 0.012MPa |
Checking 2: back washing effect
The state (situation of pressure differential) of deep filter when the situation of table 2 demonstration in the deep filter of aperture 1 μ m and 25 μ m, carrying out respectively continuous filtration running and the filtration running that hockets, back washing running.Filter, the alternate-running of back washing refers to repeatedly replace in per 5 minutes and filters running and turn round with back washing.In the situation of continuous filtration running, the deep filter of 25 μ m can carry out 2 hours approximately, and the deep filter of 1 μ m in the time of about 40 minutes pressure differential just can rise, and then block deep filter.Filter, during the back washing alternate-running, no matter be 1 μ m or the deep filter of 25 μ m, pressure differential does not rise yet after turning round continuously 5 hours, and deep filter can not block yet.
[table 2]
| The aperture | The continuous filtration running | Filtration/back washing alternate-running |
| ?1μm | Pressure differential rises in the time of about 40 minutes, filter blocks | Later also not rising of pressure differential in 5 hours |
| ?25μm | Pressure differential rises in the time of about 2 hours, filter blocks | Later also not rising of pressure differential in 5 hours |
Checking 3: the water quality of filtered water
Table 3 demonstration aperture respectively is in the deep filter of 1 μ m, 10 μ m and 25 μ m, the sized particles quantity at different levels (granule number in the water) and the clearance that are contained among former water and the filtered water 1ml.The denominator of each data is a granule number in the water in the former water, and molecule then is a granule number in the water in the filtered water, and the numerical value in the bracket is then represented clearance).In the deep filter of aperture 25 μ m, can remove above particle of the above particle of about 96% particle diameter 25 μ m, about 88% particle diameter 10 μ m and the 60% above above particle of particle diameter 1 μ m.Moreover, in the deep filter of aperture 1 μ m, can remove the particle more than the particle diameter 25 μ m more than 99%, about 94% the above particle of particle diameter 10 μ m, also removed the above particle of the particle diameter 1 μ m more than 90%.
[table 3]
| Particle diameter | Aperture: 1 μ m | Aperture: 25 μ m |
| More than the 1 μ m | More than 1985/20000 (more than 90%) | More than 7634/20000 (more than 61%) |
| More than the 10 μ m | 111/1829(94％) | 139/1153(88％) |
| More than the 25 μ m | 1/249 (more than 99%) | 4/94(96％) |
Checking 4: the input amount of reagent
Table 4 be shown as handle through the filtered water behind this deep filter 10 the concentration of the required reagent (hypochlorite) of residual bacterium and microorganism." nothing " refers to not filter, and promptly primary seawater, the deep filter 10 of aperture 50 μ m are that known Ballast Water uses when making.Can know from table 4, compare with the deep filter of known 50 μ m, when the aperture is 30 μ m effect a little less than; But when using the deep filter 10 of 25 μ m; Only need 1/3rd concentration of known 50 μ m, and under the condition of 1 μ m, only need 1/8th known following concentration to get final product.Therefore, the aperture of deep filter is preferably below the 25 μ m.
[table 4]
| Aperture (μ m) | Required reagent (hypochlorite) concentration (ppm) | Remarks |
| Do not have | More than 10 | Primary seawater |
| 50 | 8 | Known |
| 30 | 5 | |
| 25 | 3 | |
| 10 | Below 1 |
From verifying that 1 result can know, even the aperture of employed deep filter 10 is 1 μ m in this example, almost there is not the pressure loss yet, so the projected area of deep filter 10 can be implemented less, can suppress the maximization of filter element 4.In addition, can know,, can reuse through carrying out back washing from verifying 2 result.Life-saving greatly thus.Moreover, can know from verifying 3 result, when the aperture is 25 μ m, removed above planktonic organism, the above planktonic organism of 10 μ m more than 80% of 50 μ m more than 90%.In addition, can know that with the filter in comparison of known use aperture 50 μ m, the filter of aperture 25 μ m only needs the reagent of 1/3rd concentration from verifying 4 result.Therefore, the aperture of deep filter 10 can be made as 1～25 μ m.
Fig. 5 is the stereogram that shows the filter element 4A of the present invention's the 2nd example that possesses a plurality of deep filters 10.Identical with the 1st example; Filter element 4A is made up of with the tubular cabinet 9A that takes in this filter material filter material 38; This framework 9A has filtered water stream outlet 16A, former water supply port 18A, outlet 22A, gas supply port 24A, and filtered water stream exports 16A and gas supply port 24A is common.The configuration of these filtered water stream outlets 16A, former water supply port 18A, outlet 22A, gas supply port 24A is identical with the 1st example with function.
The cap 9Ac of free switch is set on the top of framework 9A, base plate 9Ad is set in the bottom.On base plate 9Ad, each deep filter 10 corresponding position is provided with circular through hole 52, and the hollow bulb 11 of each deep filter 10 is communicated with filtered water stream outlet 16A and gas supply port 24A.In the 2nd example, use with fixed head 40 fixing a plurality of deep filters 10 two ends incorporate adjunct unit as filter material 38.Fixing means for example bonds with binding agent, but is not limited to this mode.With closure member 13 (Fig. 2) sealing one end, that is, except two ends are the hollow cylindrical of opening, other is not identical with the 1st example for each deep filter 10.In this example, used 19 deep filters 10, but the quantity of deep filter 10 is not limited thereto.
Fig. 6 is the plane of fixed head 40.Fixed head 40 for example is made up of resinous sheet material, and forms circular open 46 in each deep filter 10 corresponding position.The diameter of opening 46 is set littler than the external diameter of deep filter 10.In this example,, also can be other polygonal or circle though fixed head 40 is a hexagon.One sidepiece of fixed head 40 forms by chimeric groove 48, is entrenched on the enchasing plate 44 of framework 9A, with the position of location filter material 38 peripheral direction with respect to framework 9A.
Secondly, use Fig. 5 that the installation method of the filter element 4A of the 2nd example is described.At first, use binding agent etc. are fixed in fixed head 40 with the two ends and the opening 46 involutory modes of deep filter 10 with each deep filter 10, and filter material 38 is accomplished as adjunct unit in integrated back.
Then, as shown in Figure 5, under the state of chimeric enchasing plate 44 to framework 9A, filter material 38 is inserted framework 9A by chimeric groove 48 with fixed head 40.Close cap 9Ac, seize on both sides by the arms to support filter material 38 securely through cap 9Ac and base plate 9Ad thus.
Here, because the top of deep filter 10 is through cap 9Ac sealing, so the through hole 52 of the base plate 9Ad that the filtered water FW in the hollow bulb 11 of deep filter 10 will be through the bottom, from filtered water stream outlet 16A discharge.In addition, introduce the back washing of filter element 4A from gas supply port 24A and use compressed air A, introduce the hollow bulb 11 of deep filters 10, clean deep filter 10 from the through hole 52 of base plate 9Ad.
According to the 2nd example, except having the effect identical, form filter material 38 because making up a plurality of deep filters 10 with the 1st example, so increased filter area, can filter effectively.Further, because with a plurality of deep filter 10 integrated formation adjunct units, so the filter material 38 through replacing integrated can easily be replaced a plurality of deep filters 10.

In this example; Ballast pump 2, ballasting jar 6, blender 26, reagent trough 28 and former water passage 5, water delivery path 8, air supply passageway 12 and drain passageway 14; Also can use existing equipment in the boats and ships; Can exchange with existing assembly only with filter element 4B, 4C of this example and the part that connects each branch's pipe arrangement.In addition, each valve B1～B4 and C1～C4 can use pneumatic operated valve, motor-driven valve, magnetic valve or not use the hand-operated valve etc. of controller.
Secondly, use Fig. 8 and Fig. 9 that the method for operation of the Ballast Water manufacturing installation of this example is described.Fig. 8 is the 1st filter element 4B when filtering, the system diagram when the 2nd filter element 4C is carrying out back washing.At this moment, it is opening that the 1st former water flows into valve B1, the 1st filtered water induction valve B2, the 2nd former water inflow valve C1, the 2nd air supply valve C3 and the 2nd dump valve C4, and the 1st air supply valve B3, the 1st dump valve B4 and the 2nd filtered water induction valve C2 are closed condition.Former water RW through ballast pump 2 is supplied with through the 1st and the 2nd former water branch path 5B, 5C, is supplied to the 1st and the 2nd filter element 4B, 4C.Be supplied to the former water RW of the 1st filter element 4B, filter, send water branch path 8B to deliver to ballasting jar 6 through water delivery path 8 from the 1st through deep filter 10.On the other hand; Pass through the 2nd air tributary circuit 12C from air compressor (not shown) compressed and supplied air A; Be supplied to the 2nd filter element 4C, deep filter 10 is carried out back washing, and discharge tributary circuit 14C from the 2nd and discharge outside boats and ships through drain passageway 14 with former water RW.The arrow RA that representes among the figure is the flow direction of former water RW, and arrow FA is the flow direction of filtered water FW, and arrow A A is the flow direction of compressed air A.
Fig. 9 is that the 2nd filter element 4C filters, the system diagram when the 1st filter element 4B is carrying out back washing.At this moment, the 1st former water flows into valve B1, the 1st air supply valve B3, the 1st dump valve B4, the 2nd former water flows into valve C1 and the 2nd filtered water induction valve C2 is an opening, and the 1st filtered water induction valve B2, the 2nd air supply valve C3 and the 2nd dump valve C4 are closed condition.Former water RW through ballast pump 2 is supplied with through the 1st and the 2nd former water branch path 5A, 5B, is supplied to the 1st and the 2nd filter element 4B, 4C.The former water RW that is supplied to the 2nd filter element 4C filters through deep filter 10, and send water branch path 8C to deliver to ballasting jar 6 through water delivery path 8 from the 2nd.On the other hand; From air compressor (not shown) compressed and supplied air A; Be supplied to the 1st filter element 4B through the 1st air tributary circuit 12B, deep filter 10 is carried out back washing, and discharge tributary circuit 14B from the 1st and discharge outside boats and ships through drain passageway 14 with former water RW.
Replace each valve B1～B4 and the on off state of C1～C4 among repetition Fig. 8 and Fig. 9 through time-limit attachments such as timers, when making the filter element 4B (4C) of a side carry out back washing, the filter element 4C (4B) of opposite side also can filter.Though in this example, be provided with two filter element 4B, 4C, also can be provided with more than three.
According to the 3rd example, owing to the 1st and the 2nd filter element 4B, 4C can carry out back washing, filtration simultaneously, therefore can usually continue to filter, can shorten the manufacturing time of Ballast Water.In addition, even suppose the filter element 4B (4C) of a side abnormality takes place, opposite side filter element 4C (4B) still can hocket filtration and back washing and use, and can make Ballast Water, has therefore promoted the reliability of total system.
Figure 10 shows the filter element 4D of the 4th example.In this example, the cylindric framework 9D of the filter element 4D of inclination is made up of another end wall 9Dc of an end wall 9Da, peripheral wall 9Db and the upside of downside, and axle center C tilts and is provided with towards oblique upper to another end wall 9Dc from an end wall 9Da.The center line C of the long side direction of deep filter 10 and the inclined angle alpha of the folded angle of horizontal H are preferably 20～70 °, more preferably 30～60 °.When inclined angle alpha is excessive; Because the size up and down of filter element 4D also can become big; Will deep filter 10D be taken out from filter element 4D top when maintenance activity such as dismantling then need the space of broad, and has served as hour, then is difficult to the air A in the framework 9D is discharged.
End wall 9Da place at framework 9D is formed with the outlet 22D that is connected to drain passageway 14; Near the end wall 9Da of peripheral wall 9Db, be formed with the former water supply port 18D that is connected to former water passage 5; Near another end wall 9Dc of peripheral wall 9Db, be formed with gas supply port 24D that is connected to gas supply passageway 12 and the filtered water stream outlet 16D that is connected to water delivery path 8.Filtered water stream outlet 16 is arranged at the topmost of Zhou Fangxiang of the peripheral wall 9b of inclination.
The axial lower side of gas supply port 24D on framework 9D peripheral wall 9Db and filtered water stream outlet 16D is provided with annular base plate 9Dd, and the openend 10Da of deep filter 10D is supported on this base plate 9Dd.Promptly; Between another end wall 9Dc on the framework 9D and base plate 9Dd, be formed with space S; And the openend 10Da of gas supply port 24D, filtered water stream outlet 16D and deep filter 10D is towards this space S, and hollow bulb 11D and the space S of deep filter 10D are interconnected.Also tilt with the deep filter 10D of framework 9D concentric, and openend 10Da is arranged at the top of blind end 10Db.Then identical about other structure with the 1st example.
According to the 4th example; Because the openend 10Da of deep filter 10D is towards the oblique upper opening; So when the back washing operation switched to deairing step, near the air the blind end 10Db of deep filter 10D can be discharged from openend 10Da, can prevent that air from residuing in the deep filter 10D; So when filtering operation, can use deep filter 10D integral body to filter efficiently.
In the 4th example, also can use a plurality of deep filter 10D, in addition, also can use 2 filter element 4D to constitute this device, further also can aforementioned structure be made up like the 3rd example like the 2nd example.
Figure 11 is the summary system diagram of the Ballast Water manufacturing installation of the present invention's the 5th example.The Ballast Water manufacturing installation 1A of this example is different with the Ballast Water manufacturing installation 1 of Fig. 1, possesses the ultraviolet irradiation unit 3 to filtered water FW irradiation ultraviolet radiation.In addition, filter element 4 has used the filter element 4D of the 4th example shown in figure 10, the filtered water stream that water delivery path 8 is connected to filter element 4 export 16 places be connected be communicated to drain passageway 14 exhaust with path 19.Exhaust is connected with the 5th automatic switch valve MV5 that plays a role as air bleeding valve with path 19, and controls driving the 5th automatic switch valve MV5 through controller 30.The 5th automatic switch valve MV5 can use pneumatic operated valve, motor-driven valve, magnetic valve or not use the hand-operated valve etc. of controller.Then the Ballast Water manufacturing installation 1 with Fig. 1 is identical about other structure.
Ultraviolet irradiation unit 3 is arranged at the upstream side of the ballasting jar 6 in the water delivery path 8.Ultraviolet irradiation unit 3 is handled with the mode of irradiation ultraviolet radiation to the planktonic organism and the mushroom that remain in filtering the filtered water FW after unit 4 filters, so have the unit housings 36 of taking in a plurality of ultraviolet lamps 34.Unit housings 36 is cylindric, is formed with the inflow entrance 29 of filtered water FW near the end of its peripheral wall, then is formed with flow export 31 near the other end.Each ultraviolet lamp 34 is for example by the such (not shown) that protection tube covers of quartz glass.Get into filtered water FW in the unit housings 36 when the path through 34 of ultraviolet lamps from inflow entrance 29, residual planktonic organism, mushroom are treated, send water delivery path 8 back to from flow export 31 again.
Secondly, use Figure 11 and Figure 12 that the How It Works of the Ballast Water manufacturing installation of the 5th example is described, promptly explain through the filter element of this example and make the method for filtered water and the method for handling through ultraviolet irradiation unit 3.Shown in figure 12, the How It Works of the Ballast Water manufacturing installation of the 5th example is identical with Fig. 1 example, by forming as the deairing step that filters preparatory process, the 1st conversion operation, filtration operation, the 2nd conversion, the 3rd conversion and back washing operation.
Operation setting makes Ballast Water manufacturing installation 1A start in the start button (not shown) of controller 30, and at first ballast pump 2 starts, and opens the 1st automatic switch valve MV1 and the 5th automatic switch valve MV5, gets into deairing step.In deairing step; Close the 2nd automatic switch valve MV2, the 3rd automatic switch valve MV3 and the 4th automatic switch valve MV4; 6 supply filtered water FW supply with under the state of compressed air A towards deep filter 10 with stopping stopping from deep filter 10 towards the ballasting jar; Filtered water FW is circulated to drain passageway 14 from the filtered water stream of filter element 4 outlet 16 through exhaust channel 19, and discharges towards outboard, carries out the exhaust of former water passage 5 and filter element 4 thus.Because filtered water stream outlet 16 is positioned near the topmost of filter element, so can let filter element 4 interior air be expelled to exhaust channel 19 smoothly from filtered water stream outlet 16.
Secondly, open the 2nd automatic switch valve MV2, get into the 1st conversion operation.In the 1st conversion operation, stopping under the state of deep filter 10 supply compressed air A, supplying with filtered water FW to drain passageway 14 and water delivery path 8 via filter element 4 respectively.
Then, close the 5th automatic switch valve MV5, get into and filter operation.Filter operation and under the compressed-air actuated state of deep filter 10 supplies, former water RW is supplied to filter element 4 with stopping, filtered water FW is delivered to water delivery path 8 in the draining that stops from deep filter 10.At this moment, the filter membrane through deep filter 10 flows into hollow bulb 11 to former water RW from deep filter 10 outsides, removes the foreign matter among the former water RW thus, filters.Filtered water FW supplies with through inflow entrance 29 and towards ultraviolet irradiation unit 3.
In ultraviolet irradiation unit 3, get into the filtered water FW in the unit housings 36, in the ultraviolet ray irradiation that receives ultraviolet lamp 34 through unit housings 36 when inner, and after planktonic organism, mushroom etc. handled, resupply to ballasting jar 6.
Secondly, open the 4th automatic switch valve MV4, get into the 2nd conversion operation.The 2nd conversion operation is stopping under the state of deep filter 10 supply compressed air A, through supplying with former water RW to filter element 4, make filtered water FW be circulated to water delivery path 8, and former water RW being circulated to drain passageway 14.
Then, close the 2nd automatic switch valve MV2, get into the 3rd conversion operation.In the 3rd conversion operation, stopping under the state of depth-type filtration gas 10 supply compressed air A, making former water RW be circulated to drain passageway 14 with stopping towards ballasting jar 6 supply filtered water FW from deep filter 10.So, through stopping to supply with filtered water FW, prepare the opposite direction that filtered water FW flows in the follow-up back washing operation of beginning court and supply with compressed air A from deep filter 10.
Secondly, under the state of closing the 2nd automatic switch valve MV2, open the 3rd automatic switch valve MV3, get into the back washing operation.In the back washing operation; Stopping under the state of ballasting jar 6 supply filtered water FW; Former water RW is supplied to filter element 4 on one side, towards the hollow bulb 11 of deep filter 10 supplies with compressed air A on one side, and make this compressed air A and former water RW together flow to drain passageway 14.Thus, compressed air A with the opposite direction of filtering operation through deep filter 10, with the foreign matter that is attached to deep filter 10 be piled up in foreign matters in the framework 9 toward filter element 4 outer derivation, and discharge the outside toward boats and ships S from drain passageway 14.After accomplishing the back washing operation, close the 3rd automatic switch valve MV3 and the 4th automatic switch valve MV4, and open the 5th automatic switch valve MV5, get back to deairing step.After this repeat this circulation.
According to the 5th example, can obtain the effect identical with Fig. 1 Ballast Water manufacturing installation 1.Moreover, because most planktonic organism is removed through deep filter 10 in advance in the seawater, can suppress uitraviolet intensity and reduce, so a spot of ultraviolet lamp 34 only need be set, can reach ultraviolet irradiation unit 3 miniaturizations and reduce consumes electric power.
Moreover, when the aperture of filter membrane is 1～10 μ m, be not only planktonic organism, the particle that swims (SS composition) of size also can be got rid of about 1 μ m, so the turbidity among the former water RW is significantly reduced, improves its transparency significantly.Its result; When carrying out the ultraviolet ray irradiation; Can significantly improve the transmission of ultraviolet ray in former water RW, owing to can improve ultraviolet transmission, less the getting final product of then required ultraviolet irradiation amount; For example can reduce the number that is provided with of ultraviolet lamp 34, so can reach the miniaturization of ultraviolet irradiation unit 3 and reduce consumes electric power.For the dirt of removing protection tube is absorbed by dirt to prevent ultraviolet ray; So scaler is set on protection tube; But this example can significantly reduce the dirt that is attached to ultraviolet lamp 34 surfaces; So need not to be provided with scaler as before, not only can further suppress power consumption, also can improve the maintainability of ultraviolet irradiation unit 3.
Moreover; The openend 10a of deep filter 10 is towards the oblique upper opening; Therefore when the back washing operation switches to deairing step; Near the blind end 10b of deep filter 10 air can be discharged from openend 10a, can prevent that air from residuing in the deep filter 10, so in filtering operation, use the integral body of deep filter 10 to filter efficiently.When excessive with respect to the formed inclined angle alpha of this horizontal mode; Because it is big that the size of filter element 4 above-below directions becomes; When maintenance such as taking off; In order to take out the space that just needs broad from filter element 4 tops with deep filter 10, and the inclination angle is when too small, and near the compressed air A the blind end 10b in the filter element 4 then are difficult to discharge.Therefore, this inclined angle alpha is preferably 20～70 °.

Then, to the above particle of existing 10 μ m in the former seawater, in the filtered water of embodiment 1～6 and comparative example 1, measure separately, obtain its clearance with particle collector.Moreover, insert in the quartzy unit that optical path length is 30mm (quartz cell) this filtered water and irradiation ultraviolet radiation (20W lamp), measure uitraviolet intensity (wavelength 254nm) with the UV intensitometer again through quartzy unit.Its result is as shown in table 6.Can know that by table 2 then the ultraviolet (uv) transmission degree is high more to get rid of more particles that swims.
[table 6]
To in every 1L, containing 3.0 * 10
2The seawater of individual animality planktonic organism (least part is more than the 50 μ m), and in every 1cc, contain 1.5 * 10
4The seawater (25 ℃ of water temperatures) of individual vegetalitas planktonic organism (size is 8～12 μ m); Filter with the flow of 25L/ branch and through the embodiment 1～6 of table 5, the deep filter of comparative example 1 and the deep filter that the aperture is 50 μ m (comparative example 2), actual measurement is present in the planktonic organism number in the filtered water again.
Its result is as shown in table 7, and in embodiment 1～6, most animality planktonic organism all is removed, and the animality planktonic organism that comparative example is 2 residual about 40% is arranged more than 20% but comparative example 1 is still residual.In addition, about the vegetalitas planktonic organism, embodiment 1,2 almost all is removed, and embodiment 3 has removed more than 99%, and it is about 99% that embodiment 4 has removed, and embodiment 5 has removed more than 96%, and embodiment 6 has removed about 92%.To this, comparative example 1 is still residual to be had more than 60%, and 2 of comparative examples are residual to be had more than 90%.
[table 7]
Moreover viewed vegetalitas planktonic organism is 100/a situation more than the cc in filtered water, then inserts in the quartzy unit that optical path length is 10mm this filtered water and irradiation ultraviolet radiation lamp (20W).Irradiation ultraviolet radiation is below animality, vegetalitas planktonic organism existence number separately reaches one of percentage in the filtered water, and the ultraviolet ray amount that it shone is as shown in table 7.In the comparative example 1 and 2, owing to still residual in the filtered water a considerable amount of animality planktonic organisms are arranged, in order to reduce this planktonic number, so comparative example 1 needs more than 5 times of embodiment 6, the ultraviolet energy of 2 needs of comparative example more than 6 times.
Embodiment 7, comparative example 3
Use the deep filter (hollow cylindrical of external diameter 60mm, internal diameter 30mm, length 250mm) of aperture 3 μ m; And assign to be directed against nature seawater (26 ℃ of water temperatures) with flow 25L/ and filter; The situation (embodiment 7) of at this moment, minute just carrying out air back washing (air pressure 100kPa, 5 seconds) to the situation of filtering continuously (comparative example 3) and every filter 23 each other relatively.The result is as shown in table 8.After this situation of filtering continuously because of filter blocks pressure differential in 30 minutes the time rises rapidly, and almost can't make the seawater circulation, but in the situation that is the free circulation of vital energy in the wrong direction to wash, still stable through pressure differential after 600 minutes.
[table 8]
Figure 13 is the summary system diagram of the Ballast Water manufacturing installation of the 6th example of the present invention.Be with the difference of the 5th example of Figure 11; The Ballast Water manufacturing installation 1B of the 6th example have calcium hypochlorite is dropped into filtered water FW chemical treatment 33 to replace the ultraviolet irradiation unit 3 of Figure 11, other formation, How It Works are all identical with the 5th example.
Between branch point 8a and confluence 8b, be provided with throttle mechanism 25, reduce flow through the filtered water FW of water delivery path 8 like flow controller.Throttle mechanism 25 can make the area of passage dwindle, and therefore, the pressure of throttle mechanism 25 porch can be higher than the pressure in exit.Its pressure differential is preferably about 1～10kPa.Through this pressure differential, the part of the filtered water FW of the branch point 8a of high pressure side can flow into tributary circuit 15, and via container 35 and conflux path 17 and get back to the confluence 8b of low-pressure side.Therefore, need not to be provided with the pump that filtered water FW is supplied to container 35 usefulness from water delivery path 8.
The path 17 that confluxes is provided with the 6th self regulating valve MV6 in order to the adjustment concentrated solution discharge; The downstream of the blender 39 of water delivery path 8 is to be provided with to measure the residual meter of the chlorine M that the chlorine residual concentration in the filtered water FW is used; Through the flow of the 6th self regulating valve MV6 adjustment concentrate, control makes the chlorine residual concentration in the filtered water FW become setting value.Through the driving of controller 30 controls the 6th self regulating valve MV6, the 6th self regulating valve MV6 can use pneumatic operated valve, motor-driven valve, magnetic valve or not use hand-operated valve of controller or the like.
In the 6th example, also can reach the effect identical like Fig. 1 Ballast Water manufacturing installation 1.Moreover; Can be with its seizure under the state that lets most of planktonic organism survive; A large amount of agent treated planktonic organisms are given in the throwing that need not thus as known, so can reduce the use amount of reagent, also need not the operation that neutralizes with reducing agent when Ballast Water is flow back to seawater.Its result, but the cheap Ballast Water manufacturing installation of construction miniaturization and disposal cost.
In addition, because chemical treatment 33 has been used solid calcium hypochlorite, they are different with liquid reagent, and transportation easily.In addition, the fusing point of calcium hypochlorite is higher, so preservation is easier in the hull that forms high temperature easily.
Moreover; Between the branch point 8a and confluence 8b of water delivery path 8; Be provided with the throttle mechanism 25 that filtered water FW flow is reduced, be supplied to the container 35 of taking in solid calcium hypochlorite from branch point 8a, therefore need not to be provided with feed mechanisms such as dedicated pump because of reducing the additional filtered water FW of flow; Not only simplify formation, also can reduce required electric power.
In addition, solid calcium hypochlorite is accommodated in the closed container 35, leaks in the hull so can suppress the smell of chlorine.Moreover, when changing solid calcium hypochlorite, can change, so calcium hypochlorite can directly not contact the air in human body or the hull together with container.
Figure 14 is the system diagram of the chemical treatment 33A in the Ballast Water manufacturing installation of the 7th example.The 7th example is that the chemical treatment 33 with the 6th example replaces with chemical treatment 33A, and constituting in addition is identical with the 6th example.In the 6th example; Employed granular solids calcium hypochlorite is all once dissolved and constitutes; Among the chemical treatment 33A in phase diagram; For most granular solids calcium hypochlorite is stored in the funnel 50 with graininess, becomes suitably and will be dissolved to dissolving tank 53 through the part after measuring 51 measurements of pipe and constitute.The measurement pipe 51 of this example has the weight sensor (not shown), can detect the granular solids calcium hypochlorite and whether reach desired weight.The structure that measures pipe 51 is not to be defined in this, and for example, whether it reaches specific volume also to can be detection.The measurement pipe 51 of the bottom of funnel 50 and its below interconnects through the 1st valve 54, and 53 warps of dissolving tank the 2nd valve 55 that measures pipe 51 and its below interconnects.
In the 7th example, funnel 50 is filled with the granular solids calcium hypochlorite of (for example 1000g) in a large number, opens the 1st valve 54 at any time, the granular solids calcium hypochlorite is imported measure pipe 51.Measure the amount (for example 45g) of required granular solids calcium hypochlorite by measuring pipe 51, close the 1st valve 54 backs and open the 2nd valve 55, and the amount of required granular solids calcium hypochlorite is imported dissolving tank 53.Close the 2nd valve 55 after the importing again.Make filtered water FW flow into dissolving tank 53 by the tributary circuit of paying in 8 minutes from the water delivery path 15; Stir through dissolving tank 53 set mixers 56 again; And make the granular solids calcium hypochlorite be dissolved in filtered water FW to process the calcium hypochlorite of high concentration (for example 3000mg/L); And conflux to water delivery path 8 through confluxing path 17, stir with blender 39, modulate the for example processing water of effective chlorine density 1mg/L.In this example, drop into the moment of granular solids calcium hypochlorite, the numerical value of the moment of promptly opening the 1st valve 54 by the residual meter of chlorine M determines, but also can set through timer, also can use other means.
According to the 7th example, not only can reach the effect identical, and only produce the high concentration hypochlorous acid calcium solution with aequum with the 6th example, so the high concentration hypochlorous acid calcium solution can not be stranded in the dissolving tank 53 for a long time, can alleviate the corrosion of dissolving tank 53.Moreover funnel 50 is for to be arranged in the space of bone dry, so can replenish the granular solids calcium hypochlorite easily.
Use the deep filter 10 of this example, carry out confirmatory experiment.Employed deep filter is the hollow cylindrical of long 250mm, external diameter 60mm, internal diameter 30mm; The aperture respectively is 1 μ m (embodiment 8), 3 μ m (embodiment 9), 10 μ m (embodiment 10), 15 μ m (embodiment 11), 25 μ m (embodiment 12), 30 μ m (comparative example 4), 50 μ m (comparative example 5), and the relative horizontal plane in the axle center of deep filter is provided with 45 ° the mode of tilting.As former water, in every 1L, containing 3.0 * 10
2The seawater of individual animality planktonic organism (least part is more than the 50 μ m), and in every 1cc, contain 1.5 * 10
