Description
本発明は、水処理装置に係り、特に船舶内の純水製造装置に好適な水処理装置に関する。
The present invention relates to a water treatment apparatus, and more particularly to a water treatment apparatus suitable for a pure water production apparatus in a ship.
海洋を航行する船舶では、飲料水や生活用水等の水を確保することが重要となる。そこで船舶には、海水から蒸留等により淡水を造水する造水装置が搭載されていることが多い。造水装置で製造した淡水は飲料水等のほかボイラ給水としても使用されることがある(特許文献1)。
Securing water such as drinking water and domestic water is important for ships navigating the ocean. Therefore, a ship is often equipped with a fresh water generator that produces fresh water from seawater by distillation or the like. Fresh water produced by a fresh water generator may be used as boiler water as well as drinking water (Patent Document 1).
船内におけるボイラは例えば以下のような用途で用いられている。
(1) タービン船では過熱蒸気をタービンに供給する蒸気発生装置として主ボイラを設置する。
(2) ディーゼル船では、燃料、潤滑油、冷却清水の加熱、調理、給湯、暖房などのために大量の蒸気が必要であり、ディーゼル機関を補うために飽和蒸気を供給する補助ボイラを設置する。
(3) タンカー船では、カーゴタンク内の揮発性ガスを押し出すためのイナートガスとして酸素濃度≦5%のボイラ排気(不燃性)を供給するためのボイラを設置する。 Boilers in ships are used for the following purposes, for example.
(1) In the turbine ship, a main boiler is installed as a steam generator for supplying superheated steam to the turbine.
(2) Diesel ships need a large amount of steam for heating, cooking, hot water supply, heating, etc. for fuel, lubricating oil, cooling fresh water, and install an auxiliary boiler that supplies saturated steam to supplement the diesel engine .
(3) In a tanker ship, a boiler for supplying boiler exhaust (non-combustible) with an oxygen concentration ≦ 5% is installed as an inert gas for pushing out the volatile gas in the cargo tank.

(3) In a tanker ship, a boiler for supplying boiler exhaust (non-combustible) with an oxygen concentration ≦ 5% is installed as an inert gas for pushing out the volatile gas in the cargo tank.
従来はいずれの用途においても船内ボイラとして低圧・中圧ボイラが主に用いられている。この場合は、ボイラ給水として淡水を用いたときに淡水の水質が運転不良につながることは少ない。
Conventionally, low-pressure / medium-pressure boilers are mainly used as inboard boilers in any application. In this case, when fresh water is used as boiler feed water, the quality of the fresh water rarely leads to poor operation.
タービン船は蒸気タービンを稼働するための蒸気を主にボイラで製造する必要があり燃費へのボイラ稼働台数の影響が大きい。そこで近年、ボイラとして高圧ボイラを使用して1台の高圧ボイラで複数の蒸気タービンを稼働することで、ボイラ稼働台数を削減して燃費の改善を図る取組みが検討されている。
Turbine ships need to produce steam for operating steam turbines mainly in boilers, which greatly affects the number of boilers operating on fuel efficiency. Therefore, in recent years, an approach for reducing fuel consumption by reducing the number of operating boilers by using a high-pressure boiler as a boiler and operating a plurality of steam turbines with one high-pressure boiler has been studied.
船内ボイラとして高圧ボイラを使用する場合は、ボイラ給水が高温であるため水質の悪さ(例えば腐食性)がボイラの運転不良に繋がりやすい。ボイラが運転不良となったときの影響が甚大であることから、ボイラ給水の水質を淡水からさらに高度化し、脱塩処理した純水をボイラ給水として使用することが望ましい。
When a high-pressure boiler is used as an inboard boiler, since the boiler feed water is hot, poor water quality (for example, corrosiveness) tends to lead to poor operation of the boiler. Since the influence when a boiler becomes inoperable is enormous, it is desirable to further improve the quality of boiler feedwater from fresh water and use demineralized pure water as boiler feedwater.
ボイラ用純水製造装置として、UF膜装置とRO装置と電気膜イオンとを直列に設置したものが知られている(特許文献2)。
As a pure water production apparatus for boilers, an apparatus in which a UF membrane device, an RO device, and electric membrane ions are installed in series is known (Patent Document 2).
通常の場合、船内には交換部品が保管されていないので、航行中に純水製造装置が部品の劣化、損傷、閉塞等によって運転が不調になっても、部品を交換できず、不調を解消できない。

図1は実施の形態に係る水処理装置としての純水製造装置を示すものである。
FIG. 1 shows a pure water production apparatus as a water treatment apparatus according to an embodiment.
海水を蒸留して得られた淡水が淡水タンク1内に導入される。淡水タンク1内の淡水の一部は、低圧ボイラ又は中圧ボイラの給水として用いられる。淡水タンク1内の淡水は、主系列10を構成する配管2、バルブ3、給水ポンプ4及びMF(精密濾過)膜装置5を介してRO(逆浸透)装置6へ供給される。RO装置6の濃縮水は、配管7を介して淡水タンク1に返送され、その一部は配管7から分岐したブロー配管8及びブロー弁9を介して系外に排出される。
Fresh water obtained by distilling seawater is introduced into the fresh water tank 1. A part of the fresh water in the fresh water tank 1 is used as water supply for a low pressure boiler or an intermediate pressure boiler. Fresh water in the fresh water tank 1 is supplied to an RO (reverse osmosis) device 6 via a pipe 2, a valve 3, a feed water pump 4 and an MF (microfiltration) membrane device 5 constituting the main series 10. The concentrated water of the RO device 6 is returned to the fresh water tank 1 through the pipe 7, and a part thereof is discharged out of the system through the blow pipe 8 and the blow valve 9 branched from the pipe 7.
RO装置6の透過水は、電気脱イオン装置11に供給される。電気脱イオン装置11は、特許文献2の通り、陰極及び陽極と、該陰極と陽極の間に配列された複数のカチオン交換膜及びアニオン交換膜と、これらの膜同士の間に形成された濃縮室及び脱塩室と、該脱塩室に充填されたイオン交換体と、該陽極と陰極との間に電圧を印加する電源装置とを有する。RO透過水は、該脱塩室を通過する間に脱イオン処理され、純水となる。この純水は、配管12及びバルブ13を介して一部が取り出され、高圧ボイラ等の給水として使用される。純水の残部は、配管15を介して淡水タンク1へ返送される。電気脱イオン装置11の濃縮水は配管16を介して淡水タンク1に返送される。
The permeated water of the RO device 6 is supplied to the electrodeionization device 11. As in Patent Document 2, the electrodeionization apparatus 11 includes a cathode and an anode, a plurality of cation exchange membranes and anion exchange membranes arranged between the cathode and anode, and a concentration formed between these membranes. A chamber, a desalting chamber, an ion exchanger filled in the desalting chamber, and a power supply device for applying a voltage between the anode and the cathode. The RO permeated water is deionized while passing through the desalting chamber to become pure water. Part of this pure water is taken out via the pipe 12 and the valve 13 and used as water supply for a high-pressure boiler or the like. The remaining pure water is returned to the fresh water tank 1 via the pipe 15. The concentrated water of the electrodeionization apparatus 11 is returned to the fresh water tank 1 through the pipe 16.
この純水製造装置において、電気脱イオン装置11からの純水の水量が規定値よりも少なかったり、電気脱イオン装置11からの純水の水質が悪い(具体的には、例えば電気伝導度やTOC値が規定値よりも高い)などの不調が生じたときには、不調原因となる部品を管理部門のサーバに送信手段(例えば衛星通信システム)によって送信する。該サーバは、該交換部品情報と次の寄港地情報(場所、時期)とを交換部品納入部門に送信(発注)し、次の寄港地で直ちに部品を交換できるように手配しておく。
In this pure water production apparatus, the amount of pure water from the electrodeionization apparatus 11 is less than a specified value, or the quality of pure water from the electrodeionization apparatus 11 is poor (specifically, for example, electric conductivity or When a malfunction such as a TOC value higher than a specified value occurs, the component causing the malfunction is transmitted to a server in the management department by a transmission means (for example, a satellite communication system). The server transmits (orders) the replacement part information and the next port information (location, time) to the replacement part delivery department, and arranges the parts so that the parts can be immediately replaced at the next port.
図2を参照して別の実施の形態について説明する。
この実施の形態では、図1に示した純水製造装置を主系列として備えると共に、これとは別にさらに予備系列20を備える。 Another embodiment will be described with reference to FIG.
In this embodiment, the pure water production apparatus shown in FIG. 1 is provided as a main series, and aspare series 20 is further provided separately from this.
この実施の形態では、図1に示した純水製造装置を主系列として備えると共に、これとは別にさらに予備系列20を備える。 Another embodiment will be described with reference to FIG.
In this embodiment, the pure water production apparatus shown in FIG. 1 is provided as a main series, and a
予備系列20は、淡水タンク1からの淡水を配管21、バルブ22、配管23及び給水ポンプ24によってMF膜装置25に通水し、MF濾過水をイオン交換樹脂装置26に通水して脱イオン処理して純水を製造するよう構成されている。予備系列20からの純水は配管27からバルブ29A、前記配管12,15を介して淡水タンク1へ返送され、使用時はバルブ13を開きバルブ13を介して一部が取り出される。
In the preliminary series 20, fresh water from the fresh water tank 1 is passed through the MF membrane device 25 by the pipe 21, the valve 22, the pipe 23, and the water supply pump 24, and the MF filtered water is passed through the ion exchange resin device 26 for deionization. It is configured to produce pure water by processing. Pure water from the preliminary line 20 is returned from the pipe 27 to the fresh water tank 1 through the valve 29A and the pipes 12 and 15, and when used, the valve 13 is opened and a part is taken out through the valve 13.
電気脱イオン装置11からの純水の水質(比抵抗又は電気伝導度など)が比抵抗計、電気伝導度計などのセンサで計測されると共に、電気脱イオン装置11からの純水流量が流量センサで計測され、これらのセンサの検出信号が制御器(図示略)に入力される。該制御器は、以上の主系列10の運転の間中、純水の水質及び水量を監視しており、水質及び水量の少なくとも一方が所定期間以上、設定値を下回る(水質が悪い又は水量が少ない)場合には、主系列10に何らかの異常が生じたものと判断し、図3のように、純水製造装置の管理部門に衛星通信システム等を利用して異常を通知すると共に、予備系列20による純水製造を開始させる。また、管理部門に交換部品を通知する。
The quality of pure water (such as specific resistance or electrical conductivity) from the electrodeionization device 11 is measured by a sensor such as a resistivity meter or an electric conductivity meter, and the flow rate of pure water from the electrodeionization device 11 is a flow rate. Measurement is performed by sensors, and detection signals from these sensors are input to a controller (not shown). The controller monitors the quality and quantity of pure water during the operation of the main series 10 described above, and at least one of the quality and quantity of water falls below a set value for a predetermined period or longer (poor water quality or water quantity is low). 3), it is determined that some abnormality has occurred in the main series 10, and the management department of the pure water production apparatus is notified of the abnormality using a satellite communication system as shown in FIG. 20 starts pure water production. In addition, the replacement part is notified to the management department.
予備系列20を作動させる場合、主系列10を停止し、純水製造装置で製造する純水の全量を予備系列20で製造してもよく(バルブ3,29Bを閉、バルブ22,29Aを開、バルブ13は使用時のみ開とする。)、主系列10及び予備系列20の双方を作動させ、主系列10からの純水と予備系列20からの純水とを合流させて取り出してもよい(バルブ29Bを閉、バルブ3,22,29Aを開、バルブ13は使用時のみ開とする。)。
When the standby system 20 is operated, the main system 10 may be stopped and the entire pure water produced by the pure water production apparatus may be manufactured by the preliminary system 20 ( valves 3 and 29B are closed and valves 22 and 29A are opened). The valve 13 is opened only during use.) Both the main series 10 and the standby series 20 are operated, and the pure water from the main series 10 and the pure water from the backup series 20 may be merged and taken out. (Valve 29B is closed, valves 3, 22, 29A are opened, and valve 13 is opened only when in use.)
上記説明の図2では、主系列10と予備系列20とを並列に設置しているが、図2中に二点鎖線で示される直列接続用配管30を設けてもよい。電気脱イオン装置11からの純水の水量は十分であるが、水質が不良の場合には、電気脱イオン装置11からの純水を予備系列20に通水して仕上げ処理し、良好な水質の純水を配管27,12を介して取り出す。
In FIG. 2 described above, the main series 10 and the backup series 20 are installed in parallel, but a series connection pipe 30 indicated by a two-dot chain line in FIG. 2 may be provided. Although the amount of pure water from the electrodeionization apparatus 11 is sufficient, if the water quality is poor, the pure water from the electrodeionization apparatus 11 is passed through the preliminary series 20 for finishing treatment, and good water quality is achieved. The pure water is taken out through the pipes 27 and 12.
このように、主系列10と並列又は直列に通水可能な予備系列20を設置しているので、主系列10にトラブルが生じた場合でも純水を安定して製造することができる。また、高圧ボイラに純水が安定して供給されるので、船舶を次の寄港地まで航行させることができる。
As described above, since the standby series 20 that can pass water in parallel or in series with the main series 10 is installed, even when a trouble occurs in the main series 10, pure water can be stably produced. In addition, since pure water is stably supplied to the high-pressure boiler, the ship can be navigated to the next port of call.
上記図1,2の実施の形態では、淡水タンク1内の淡水を予備系列20へ供給する配管21は淡水タンク1に直接に接続されているが、該配管21は配管2から分岐されてもよい。
In the embodiment shown in FIGS. 1 and 2, the pipe 21 for supplying the fresh water in the fresh water tank 1 to the standby system 20 is directly connected to the fresh water tank 1, but the pipe 21 may be branched from the pipe 2. Good.
上記実施の形態ではMF膜装置5が用いられているが、UF膜装置が用いられてもよい。これらの膜装置は省略されてもよい。図1,2では、RO装置6は1段だけ図示されているが、2段以上に設置されてもよい。
In the above embodiment, the MF membrane device 5 is used, but a UF membrane device may be used. These membrane devices may be omitted. 1 and 2, only one stage of the RO device 6 is shown, but it may be installed in two or more stages.
イオン交換樹脂装置26は、省スペースである;立ち上がりが早い;原水水質の変動に耐えられる;メンテナンス作業が簡易または不要である等の特徴を有している。イオン交換樹脂装置は、電気脱イオン装置等に比べて、破過までの寿命が短いが、次の寄港地まで短期間だけ安定して脱塩処理できればよいので、予備系列20にイオン交換樹脂装置を用いることができる。特に装置の単純化による省スペース化を図るため非再生型のイオン交換樹脂装置とすることが好ましい。
The ion-exchange resin device 26 is space-saving; has a fast start-up; can withstand fluctuations in the quality of raw water; and has features such as simple and unnecessary maintenance work. The ion exchange resin apparatus has a shorter life until breakthrough compared to an electrodeionization apparatus or the like, but it is only necessary to stably demineralize for a short period until the next port of call. Can be used. In particular, in order to save space by simplifying the apparatus, it is preferable to use a non-regenerative ion exchange resin apparatus.
イオン交換樹脂装置としては1塔のみ、または2塔直列で配置すればよい。2塔の場合、カチオン交換→アニオン交換、アニオン交換→カチオン交換、アニオン・カチオン混合→アニオン・カチオン混合など各種の組み合わせを採用することができる。また、塔内に層状態でカチオン交換樹脂とアニオン交換樹脂を充填する方式や、塔内に水平遮水板で上室・下室に区分すると共に上室から排水して下室に導入する配管を設ける方式など1塔でカチオン交換・アニオン交換の2段処理を行うようにしてもよい。
As the ion exchange resin apparatus, only one tower or two towers may be arranged in series. In the case of two towers, various combinations such as cation exchange → anion exchange, anion exchange → cation exchange, anion / cation mixture → anion / cation mixture can be employed. In addition, the cation exchange resin and anion exchange resin are packed in the tower in a layered state, and the pipe is divided into the upper and lower chambers with horizontal water shielding plates in the tower and drained from the upper chamber and introduced into the lower chamber A two-stage treatment of cation exchange / anion exchange may be performed in one tower, such as a method of providing a cation.
より安定処理が求められる場合には、図2の通り予備系列においてMF膜装置25やUF膜装置などにより膜濾過処理を行うことが好ましい。
When more stable treatment is required, it is preferable to perform membrane filtration treatment with the MF membrane device 25 or the UF membrane device in the preliminary series as shown in FIG.
主系列10とは異なる除去メカニズムの予備系列20を設置することにより、主系列と同じ原因でのトラブルを回避できるというメリットもある。
There is also an advantage that troubles caused by the same cause as that of the main series can be avoided by installing the preliminary series 20 having a removal mechanism different from that of the main series 10.
図2の場合、主系列10が正常運転している間は、予備系列20は基本的に脱塩には使用せず、浸漬状態で通水停止してもよいが、菌の発生を抑制して、切替え後にすぐに採水できるように、配管28を用いて予備系列20内で水を循環させてスタンバイしておくことが好ましい(バルブ22,29Aを閉、バルブ3,29Bを開、バルブ13は使用時のみ開とする。)。この場合、予備系列内の水温の上昇(50℃超)やイオン交換樹脂からの溶出有機物の蓄積が懸念されるため、定期的に系外にブローするなどして水温や水質が所定範囲内になるよう制御するのが好ましい。また、配管28からの戻り水を淡水タンク1に戻すと、大気中のCO2が溶解した水を取込むことになりイオン交換樹脂に負荷がかかるので、配管23に返送するのが好ましい。
In the case of FIG. 2, while the main line 10 is operating normally, the preliminary line 20 is basically not used for desalination and may be stopped in the soaking state, but the generation of bacteria is suppressed. Therefore, it is preferable that the pipe 28 is used to circulate water in the standby system 20 so that water can be collected immediately after the switching (the valves 22 and 29A are closed, the valves 3 and 29B are opened, the valves are opened). 13 is open only during use.) In this case, since there is a concern about an increase in the water temperature (over 50 ° C.) in the preliminary system and accumulation of organic substances eluted from the ion exchange resin, the water temperature and water quality are kept within a predetermined range by, for example, periodically blowing out of the system. It is preferable to control so that it becomes. In addition, when the return water from the pipe 28 is returned to the fresh water tank 1, it takes in water in which atmospheric CO 2 is dissolved, and a load is applied to the ion exchange resin. Therefore, it is preferably returned to the pipe 23.
上記説明では、純水製造装置の不調現象として、純水の水量と電気伝導度又はTOC値が示されているが、不調現象としては、RO装置の圧損の過度な上昇、純水の水温の過度な上昇なども例示される。
In the above description, the amount of pure water and the electrical conductivity or the TOC value are shown as a malfunction of the pure water production apparatus. However, as the malfunction, an excessive increase in the pressure loss of the RO apparatus, the water temperature of the pure water Excessive rise is also exemplified.
前記制御器のデータベースには、これらの水量、電気伝導度、圧損、水温、TOC濃度などの基準値が登録されていると共に、各測定値が基準値を超える不調現象の発生原因となる部品が登録されている。不調現象が生じたときには、不調現象をもたらす部品が管理部門に送信される。
In the database of the controller, reference values such as the amount of water, electrical conductivity, pressure loss, water temperature, TOC concentration and the like are registered, and parts that cause the malfunction phenomenon in which each measured value exceeds the reference value. It is registered. When a malfunction occurs, a part that causes the malfunction is transmitted to the management department.
上記の基準値や不調原因部品は、管理部門のサーバに登録されていてもよい。この場合、管理部門のサーバに上記各測定項目のデータが送信され、サーバが純水製造装置を監視している。現場での純水製造装置に不調が生じた場合には、該サーバから交換部品納入部門に発注データが送信される。
The above standard values and malfunctioning cause parts may be registered in the management department server. In this case, the data of each measurement item is transmitted to the server in the management department, and the server monitors the pure water production apparatus. When a malfunction occurs in the pure water production apparatus at the site, order data is transmitted from the server to the replacement parts delivery department.
本発明では、好ましくは、上記各項目を検出するための各センサの検知結果に基づいて必要な交換部品の候補を自動演算して管理者端末に送信する。例えば検知結果と交換部品の候補を紐付けるマスタを事前に作成しておくことで自動演算が可能となる。
In the present invention, it is preferable that necessary replacement part candidates are automatically calculated based on the detection results of the sensors for detecting the items described above and transmitted to the administrator terminal. For example, automatic calculation is possible by creating in advance a master for associating detection results with replacement part candidates.
航行する船の時間毎の位置と、部品在庫の位置と配送先の寄港地の位置、予備系列の残り運転可能予測期間を関連づけて、どの在庫拠点からどの寄港地に配送するのが効率的かを自動演算して結果を管理者端末に送信する。
It is efficient to deliver from which stock base to which port by associating the position of the ship to be navigated by time, the position of parts inventory, the location of the destination port of call, and the remaining operation forecast period of the spare series. Is automatically calculated and the result is sent to the administrator terminal.
これらの結果に基づいて管理者は発注手続を行う。
Based on these results, the administrator performs ordering procedures.
寄港地に配送するよりも海上に船で配送するのが効率的であれば寄港地に配送でなく船で海上に配送することを選択することもある。
If it is more efficient to ship to the sea than to the port, you may choose to ship to the sea instead of to the port.
図3では通知と発注を順次行うフローになっているが、通知を介さず発注処理することもできる。例えば、必要な交換部品を自動的に決定し、配送方法の選定から発注手続までを自動的に完了し、発注結果を管理者に連絡することもできる。このとき管理者が在庫拠点の配送準備と並行して内容確認、顧客承認などを事後処理として行うことで対応期間の短縮を図ることができる。
In FIG. 3, the notification and ordering are performed in sequence, but the ordering process can be performed without the notification. For example, it is possible to automatically determine necessary replacement parts, automatically complete the process from the selection of the delivery method to the ordering procedure, and notify the manager of the ordering result. At this time, the management period can be shortened by performing post-processing such as content confirmation and customer approval in parallel with preparation for delivery at the inventory base.
