Description

本発明は、尿素を添加してＮＯｘを還元する触媒システム「尿素ＳＣＲ」に用いる高品位尿素水の簡易供給装置とその装置を用いた高品位尿素水供給方法に関する。   The present invention relates to a simple high-quality urea water supply device used in a catalyst system “urea SCR” for reducing NOx by adding urea, and a high-quality urea water supply method using the device.

ディーゼル自動車のエンジンから排出される排気ガスに含まれる粒子状物質（Ｐａｒｔｉｃｕｌａｔｅ Ｍａｔｔｅｒ；以下「ＰＭ」という。）及び窒素酸化物（以下「ＮＯｘ」という。）の大幅な低減のためには、エンジンから排出されるガス中のＰＭ及びＮＯｘを低減する技術の改善のみでは限界があり、排気後処理装置の導入が必要不可欠とされている。
排気後処理装置のうち、ＮＯｘを還元処理する触媒システム（以下「ＮＯｘ還元触媒」という。）としては、ＮＯｘを触媒に吸蔵又は吸着して還元する触媒システム（以下「吸蔵型ＮＯｘ還元触媒」という。）や尿素を添加してＮＯｘを還元する触媒システム（以下「尿素ＳＣＲ」という。）の導入が段階的に進められており、今後、硫黄分１０ｐｐｍ以下の軽油の普及に伴い、こうしたＮＯｘ還元触媒の浄化性能や耐久性の向上が図られると考えられている。 In order to significantly reduce particulate matter (Particulate Matter; hereinafter referred to as “PM”) and nitrogen oxide (hereinafter referred to as “NOx”) contained in exhaust gas discharged from the engine of a diesel vehicle, There is a limit to only improving the technology for reducing PM and NOx in the exhausted gas, and the introduction of an exhaust aftertreatment device is indispensable.
Among exhaust aftertreatment devices, a catalyst system that reduces NOx (hereinafter referred to as “NOx reduction catalyst”) is a catalyst system that stores NOx in the catalyst or reduces it by adsorption (hereinafter referred to as “storage type NOx reduction catalyst”). )) And a catalyst system that reduces NOx by adding urea (hereinafter referred to as “urea SCR”) is being introduced in stages, and with the spread of diesel oil with a sulfur content of 10 ppm or less, such NOx reduction It is considered that the purification performance and durability of the catalyst can be improved.

一方、ＰＭ対策として用いられるディーゼル微粒子除去装置（以下「ＤＰＦ」という。）は、一部車種を除き、新長期目標に基づく規制に対応した車両において採用が予定されており、既に実用化されている技術である。今後、更なる技術の進展及び燃料・潤滑油の品質の改善等により、その浄化性能を一層向上させることが可能と考えられる。しかしながら、高温で高い燃焼効率を求めると、ＰＭが低減できる一方で、空気中の窒素が酸化してＮＯｘが生成される。そこで高温の排ガス中に尿素を噴射し、その混合気を尿素触媒に通すことでＮＯｘを窒素と水に還元する尿素ＳＣＲと呼ばれるシステムが実用化されている。
尿素ＳＣＲに使用される高品位尿素水については、日本自動車規格（ＪＡＳＯ）によって、「ディーゼル機関−ＮＯｘ還元添加剤ＡＵＳ３２−第１部：性状（ＪＡＳＯＥ５０２）」の規格が制定されている。
高品位尿素水の製品規格は、以下の通りである。
尿素濃度：３１．８〜３３．３ｗｔ％、密度（２０℃）：１．０８７０〜１．０９２０ｇ／ｃｍ3、屈折率（２０℃）：１．３８１７〜１．３８４０，アルカリ度（ＮＨ3換算）：＜０．２％、炭酸塩（ＣＯ2換算）：＜０．２％、ビゥレット：＜０．３％、ホルムア
ルデヒド：＜１０ｍｇ／ｋｇ、不溶解分：＜２０ｍｇ／ｋｇ、燐酸（ＰＯ4）：＜０．５
ｍｇ／ｋｇ、カルシウム：＜０．５ｍｇ／ｋｇ、鉄分：＜０．５ｍｇ／ｋｇ、銅：＜０．２ｍｇ／ｋｇ、亜鉛：＜０．２ｍｇ／ｋｇ、クローム：＜０．２ｍｇ／ｋｇ、ニッケル：＜０．２ｍｇ／ｋｇ、マグネシウム：＜０．５ｍｇ／ｋｇ、カリウム：＜０．５ｍｇ／ｋｇ、ナトリム：＜０．５ｍｇ／ｋｇ。 On the other hand, diesel particulate removal equipment (hereinafter referred to as “DPF”), which is used as a measure against PM, is planned to be used in vehicles that comply with regulations based on the new long-term goal, with some models already in use. Technology. In the future, it is considered that the purification performance can be further improved by further technological progress and improvement of the quality of fuel and lubricating oil. However, when high combustion efficiency is obtained at a high temperature, while PM can be reduced, nitrogen in the air is oxidized and NOx is generated. Therefore, a system called urea SCR that reduces NOx to nitrogen and water by injecting urea into high-temperature exhaust gas and passing the mixture through a urea catalyst has been put into practical use.
As for high-grade urea water used for urea SCR, a standard of “diesel engine-NOx reducing additive AUS32-part 1: property (JASOE502)” is established by the Japan Automobile Standard (JASO).
The product standards for high-grade urea water are as follows.
Urea concentration: 31.8 to 33.3 wt%, density (20 ° C.): 1.0870 to 1.0920 g / cm 3 , refractive index (20 ° C.): 1.3817 to 1.3840, alkalinity (NH 3 conversion) ): <0.2%, carbonate (CO 2 equivalent): <0.2%, violet: <0.3%, formaldehyde: <10 mg / kg, insoluble matter: <20 mg / kg, phosphoric acid (PO 4 ): <0.5
mg / kg, calcium: <0.5 mg / kg, iron: <0.5 mg / kg, copper: <0.2 mg / kg, zinc: <0.2 mg / kg, chrome: <0.2 mg / kg, nickel : <0.2 mg / kg, magnesium: <0.5 mg / kg, potassium: <0.5 mg / kg, sodium: <0.5 mg / kg.

高品位尿素水はディーゼル自動車の走行中に消費されるので、定期的に供給・補充する必要がある。現在、以下の高品位尿素水の供給方法が提案されている。
１）容量５Ｌ、１０Ｌ及び２０Ｌの使い捨て容器（Ｂａｇ ｉｎ Ｂｏｘ）による供給方法。
２）トラックターミナルに、容量１０００ＬのＩＢＣ（Ｉｎｔｅｒｍｅｄｉａｔｅ Ｂｕｌｋ ｃｏｎｔａｉｎｅｒ）タンク（１０７０Ｌの実容量を有するＩＢＣタンク）を設置し、使用に応じて、容量１０００ＬのＩＢＣタンクを交換する供給方法。
３）トラックターミナルに、容量６００Ｌ以上のディスペンサーを設置し、使用に応じて、タンクローリーから、高品位尿素水を計量・充填する供給方法。 Since high-grade urea water is consumed while the diesel vehicle is running, it needs to be supplied and replenished regularly. Currently, the following high-grade urea water supply methods have been proposed.
1) Supply method using 5L, 10L and 20L disposable containers (Bag in Box).
2) A supply method in which an IBC (Intermediate Bulk container) tank (an IBC tank having an actual capacity of 1070 L) is installed at a truck terminal, and an IBC tank having a capacity of 1000 L is replaced according to use.
3) A supply method in which a dispenser with a capacity of 600L or more is installed in the truck terminal, and high-grade urea water is measured and filled from a tank lorry according to use.

現在、尿素ＳＣＲに使用される高品位尿素水の効率的な供給体制の確立が要請されているが、提案されている前記の供給方法には、以下の課題がある。
１）使い捨て容器（Ｂａｇ ｉｎ Ｂｏｘ）による供給方法では、使い捨て容器による包装費用と後処理費用がかかり、経済的に好ましい供給方法とはいえない。
２）容量１０００ＬのＩＢＣタンクを交換する供給方法では、ＩＢＣタンク内に残液があるので、ＩＢＣタンクを交換する毎に、タンクの洗浄充填が必要になると共に、廃液処理費用がかかる。また、使用中のＩＢＣタンクの他に予備のタンクを設置する必要が生じて、経済的に好ましい供給方法とはいえない。
本発明は、前記課題を解決するためのものである。即ち、本発明は、高品位尿素水の取扱いが簡便な簡易供給装置と、その装置を用いた高品位尿素水の効率的な供給方法を提供することを目的とする。 Currently, establishment of an efficient supply system of high-grade urea water used for urea SCR is required, but the proposed supply method has the following problems.
1) The supply method using a disposable container (Bag in Box) is not an economically preferable supply method because of the packaging cost and post-processing cost of the disposable container.
2) In the supply method in which the IBC tank having a capacity of 1000 L is replaced, since there is residual liquid in the IBC tank, each time the IBC tank is replaced, the tank needs to be cleaned and filled, and the waste liquid processing cost is required. Further, it is necessary to install a spare tank in addition to the IBC tank in use, which is not an economically preferable supply method.
The present invention is for solving the above-mentioned problems. That is, an object of the present invention is to provide a simple supply device that is easy to handle high-grade urea water and an efficient supply method of high-grade urea water using the device.

本発明の第四観点は、
１０００Ｌに定量された高品位尿素水を充填する１０５０Ｌ乃至１５００Ｌの実容量を有する高密度ポリエチレン製ＩＢＣタンクを備えた高品位尿素水の移送装置を用いて、
１０００Ｌの高品位尿素水を、第二観点記載の高品位尿素水の簡易供給装置の上部タンクの高品位尿素水注入口に流入し、その後、上部タンクより下部タンクに流し送り、そして下部タンクの高品位尿素水供給口より供給することを特徴とする、高品位尿素水の供給方法である。 The fourth aspect of the present invention is:
Using a high-grade urea water transfer device equipped with a high-density polyethylene IBC tank having an actual capacity of 1050 L to 1500 L filled with high-quality urea water quantified to 1000 L,
1000 L of high-grade urea water flows into the high-grade urea water inlet of the upper tank of the simple supply device for high-grade urea water described in the second aspect, and then flows from the upper tank to the lower tank, A high-grade urea water supply method characterized by supplying from a high-grade urea water supply port.

本発明の第五観点は、
１０００Ｌないし１００００Ｌの実容量を有するタンクローリーより、１０００Ｌ定量の高品位尿素水を、第一観点記載の高品位尿素水の簡易供給装置の上部タンクの高品位尿素水注入口に流入し、その後、上部タンクより下部タンクに流し送り、そして下部タンクの高品位尿素水供給口より供給することを特徴とする、高品位尿素水の供給方法である。 The fifth aspect of the present invention is:
From a tank lorry having an actual capacity of 1000L to 10000L, 1000L fixed amount of high-grade urea water flows into the high-grade urea water inlet of the upper tank of the high-grade urea water simple supply device described in the first aspect, The high-grade urea water supply method is characterized by flowing from the tank to the lower tank and supplying from the high-grade urea water supply port of the lower tank.

本発明の第六観点は、

From a tank lorry having an actual capacity of 1000L to 10000L, 1000L fixed amount of high-grade urea water flows into the high-grade urea water inlet of the upper tank of the high-grade urea water simple supply device described in the second aspect, The high-grade urea water supply method is characterized by flowing from the tank to the lower tank and supplying from the high-grade urea water supply port of the lower tank.

本発明によれば、高品位尿素水のディーゼル車への供給途中で下部タンクの高品位尿素水がたとえ空になったとしても、上部タンクより直ちに一定量の高品位尿素水を下部タンクに供給することができるため、ディーゼル車への高品位尿素水の供給が中断することなく、安定供給されるという利点を有する。なお且つ、本発明の高品位尿素水の簡易供給装置は、２つのタンクが互いに上下に設置されるものであるため、２つのタンクが横に並列して設置されるものよりも、設置面積が小さくて済むという利点もある。これに対し、例えば一段式タンクからなる高品位尿素水の簡易供給装置の場合においては、タンクが実質的に空でなければ、一定量の高品位尿素水を供給するとタンク容量を超えてしまう上に、空になったときに直ちに供給できる手段を有していないため、ディーゼル車への高品位尿素水の供給が中断してしまうという不利さを有する。
また本発明において、移送装置として１０００Ｌないし１００００Ｌの実容量を有するタンクローリーを用いる場合、それぞれのトラックターミナルを順次周回しながら各トラックターミナルに設置した高品位尿素水の簡易供給装置に供給できるため、各トラックターミナルへの高品位尿素水の供給が円滑に行われる。 According to the present invention, even if the high-grade urea water in the lower tank becomes empty during the supply of high-grade urea water to the diesel vehicle, a certain amount of high-grade urea water is immediately supplied to the lower tank from the upper tank. Therefore, there is an advantage that the supply of high-grade urea water to the diesel vehicle is stably supplied without interruption. In addition, since the simple supply device for high-grade urea water of the present invention has two tanks installed one above the other, the installation area is larger than that in which two tanks are installed side by side. There is also an advantage of being small. On the other hand, for example, in the case of a simple high-quality urea water supply device composed of a single-stage tank, if the tank is not substantially empty, supplying a certain amount of high-quality urea water will exceed the tank capacity. In addition, since there is no means that can be supplied immediately when it is empty, there is a disadvantage that the supply of high-grade urea water to the diesel vehicle is interrupted.
Further, in the present invention, when a tank lorry having an actual capacity of 1000L to 10000L is used as the transfer device, each tank terminal can be supplied to a simple high-quality urea water supply device installed at each truck terminal while sequentially circling each truck terminal. High quality urea water is smoothly supplied to the truck terminal.

本発明の第一観点における高品位尿素水の簡易供給装置は、ＩＢＣタンクである上部タンクと下部タンクとの二段式タンクを備える。このうち、上部タンクは、エア抜き口及び高品位尿素水注入口、並びにタンク底部に高品位尿素水流出口を有する一方で、下部タンクは、エア抜き口、高品位尿素水流入口、及び高品位尿素水供給口を有する。そして上部タンクの高品位尿素水流出口と下部タンクの高品位尿素水流入口とは、着脱バルブ付接続
ホースにより連結されている。さらに下部タンクの高品位尿素水供給口には、電動ポンプ駆動のガンノズル付供給ホースが接続されており、このガンノズル付供給ホースを介して高品位尿素水がディーゼル車へと供給される。また、用いられる上部タンクは１０５０Ｌ乃至１５００Ｌの実容量を有する高密度ポリエチレン製であり、下部タンクは１２００Ｌ乃至１５００Ｌの実容量を有する高密度ポリエチレン製である。
また、高品位尿素水の流出時における、外部よりのダストの混入を防ぐため、エア抜き口には気体用フィルタを備えていることが好ましい。気体用フィルタとしては、ステンレス製メッシュ又はポリプロピレン製不織布が使用可能である。電動ポンプは、ＩＢＣタンクの天板部分に竪形の電動ポンプを据え付けるのが好ましい。また、使用の便利さから、ガンノズル付供給ホースには、さらに流量計が接続されていることが好ましい。
本発明の第二観点における高品位尿素水の簡易供給装置は、下部タンクに電動ポンプを有していない他は上記第一観点における高品位尿素水の簡易供給装置と同様の構成を有するものであり、電動ポンプを必要とせずに、ヘッド差（高低差）を用いて自重により、高品位尿素水がディーゼル車に供給されることにある。かかる第二観点の高品位尿素水の簡易供給装置においても、エア抜き口には、さらに気体用フィルタが備えられていることが、ダストの混入防止の点で好ましい。
本発明の第三観点における高品位尿素水の供給方法によれば、例えば工場において１０００Ｌに定量された高品位尿素水を充填する１０５０Ｌ乃至１５００Ｌの実容量を有する高密度ポリエチレン製ＩＢＣタンクを備えた高品位尿素水の移送装置を用いて、上記第一観点における高品位尿素水の簡易供給装置の上部タンクの高品位尿素水注入口に流入し、その後、上部タンクより下部タンクに流し送り、そして下部タンクの高品位尿素水供給口より供給される。このように、高品位尿素水は、一定量の高品位尿素水を充填するＩＢＣタンク等の移送装置を積載した小型トラック、大型トラック等の運搬手段を用いて、トラックターミナルに運搬され、一旦、上部タンク内に充填される。そしてその後、上部タンクより下部タンクに流し送られ、そして下部タンクよりディーゼル車に供給される。
また、本発明の第四観点における高品位尿素水の供給方法によれば、上記第三観点における高品位尿素水の供給方法において、第一観点の代わりに第二観点における高品位尿素水の簡易供給装置を用いる他は、同様であり、電動ポンプを必要としない。
一方、本発明の第五観点における高品位尿素水の供給方法によれば、高品位尿素水の移送装置としてタンクローリーが用いられる他は、上記第三観点における高品位尿素水の供給方法と同様である。タンクローリーは１０００Ｌないし１００００Ｌの実容量を有することが好ましい。また、タンクローリーは、計量装置（計量検定合格済み）を備えて、１Ｌ単位にて供給することが好ましい。
本発明の第六観点における高品位尿素水の供給方法によれば、高品位尿素水の移送装置として第五観点における１０００Ｌないし１００００Ｌの実容量を有するタンクローリーを用いた他は、上記第四観点における高品位尿素水の供給方法と同様である。 The high-quality urea water simple supply device according to the first aspect of the present invention includes a two-stage tank including an upper tank and a lower tank, which are IBC tanks. Of these, the upper tank has an air vent and a high-grade urea water inlet, and a high-grade urea water outlet at the bottom of the tank, while the lower tank has an air vent, a high-grade urea water inlet, and a high-grade urea. Has a water supply port. The high-grade urea water outlet of the upper tank and the high-grade urea water inlet of the lower tank are connected by a connection hose with a detachable valve. Further, a high-grade urea water supply port of the lower tank is connected to a supply hose with a gun nozzle driven by an electric pump, and high-grade urea water is supplied to the diesel vehicle via the supply hose with a gun nozzle. The upper tank used is made of high density polyethylene having an actual capacity of 1050L to 1500L, and the lower tank is made of high density polyethylene having an actual capacity of 1200L to 1500L.
Further, it is preferable that a gas filter is provided at the air vent in order to prevent dust from entering from the outside when the high-grade urea water flows out. As the gas filter, stainless steel mesh or polypropylene non-woven fabric can be used. The electric pump is preferably installed in a bowl-shaped electric pump on the top plate portion of the IBC tank. Moreover, from the convenience of use, it is preferable that a flow meter is further connected to the supply hose with a gun nozzle.
The simple high-quality urea water supply apparatus in the second aspect of the present invention has the same configuration as the high-quality urea water simple supply apparatus in the first aspect except that the lower tank does not have an electric pump. There is a need to supply high-grade urea water to a diesel vehicle by its own weight using a head difference (height difference) without requiring an electric pump. Also in the simple high-quality urea water supply apparatus according to the second aspect, it is preferable that a gas filter is further provided at the air vent in terms of preventing dust from being mixed.

本発明で取り扱う高品位尿素水は、尿素ＳＣＲに用いるために、移送時及び保管において、金属汚染を防止する必要がある。
高品位尿素水の金属汚染を防止するため、ＩＢＣタンクにおいては、そのインナータンク材質は高密度ポリエチレンが好ましい。なお、ＩＢＣタンクでは、通常、インナータンクの保護のためケージが採用されている。ケージは、例えば、頑丈な亜鉛メッキ鋼管のフレーム構造性ケージとなっている。
下部タンクのケージは、上部タンクのケージと異なり上部タンクに高品位尿素水を充填した加重に耐えられるように強固に設計される。
電動ポンプとしては、下部タンクの底部より高品位尿素水を抜き出すことができるのであればそのポンプの形式は問わない。設置例としては、下部タンクに高品位尿素水供給口を設置し、下部タンクのケージに電動ポンプを固定する。又はタンク底部の高品位尿素水供給口にガンノズル付供給ホースを介して電動ポンプを設置する方法がある。
材質から強化プラスチック製電動ポンプが好ましい。強化プラスチック製電動ポンプは
、酸・アルカリ用途に用いられるほど耐性が優れている。構造（パイプ・プロペラ）材質には、強化プラスチックとしてポリプロピレンが好ましい。また、シャフト材質には、高耐熱耐食合金であるステンレス合金（ＳＵＳ３０４）、ハステロイ（登録商標）合金、インコネル（登録商標）合金などが好ましい。シール材質は、セラミック、フッ素樹脂、フッ素ゴム、ハステロイ（登録商標）合金、インコネル（登録商標）合金などを、特性に応じて使用するのが好ましい。ホース材質は、軟質塩化ビニルが好ましい。ガンノズル材質も、強化プラスチックとしてポリプロピレンが好ましい。
また、本発明の高品位尿素水の供給方法で使用する、高密度ポリエチレン製ＩＢＣタンクからなる高品位尿素水の移送装置は、第一観点の高品位尿素水の簡易供給装置の上部タンク又は下部タンクと実容量が異なるのみで、材質は同じものである。実際、１０００Ｌの実容量の高品位尿素水を移送できれば良く、例えば１０５０〜１５００Ｌの実容量を有する高密度ポリエチレン製ＩＢＣが用いられる。 Since the high-grade urea water handled in the present invention is used for the urea SCR, it is necessary to prevent metal contamination during transportation and storage.
In order to prevent metal contamination of high-grade urea water, in the IBC tank, the inner tank material is preferably high-density polyethylene. In the IBC tank, a cage is usually employed to protect the inner tank. The cage is, for example, a sturdy galvanized steel tube frame structural cage.
Unlike the upper tank cage, the lower tank cage is firmly designed to withstand the load of the upper tank filled with high-grade urea water.
The electric pump may be of any type as long as high-grade urea water can be extracted from the bottom of the lower tank. As an installation example, a high-grade urea water supply port is installed in the lower tank, and the electric pump is fixed to the cage of the lower tank. Alternatively, there is a method of installing an electric pump through a supply hose with a gun nozzle at a high-grade urea water supply port at the bottom of the tank.
The material is preferably an electric pump made of reinforced plastic. Reinforced plastic electric pumps are more resistant to acid and alkali applications. For the structural (pipe / propeller) material, polypropylene is preferred as the reinforced plastic. The shaft material is preferably a high heat resistant and corrosion resistant alloy such as stainless steel (SUS304), Hastelloy (registered trademark) alloy, Inconel (registered trademark) alloy, or the like. As the seal material, ceramic, fluororesin, fluororubber, Hastelloy (registered trademark) alloy, Inconel (registered trademark) alloy or the like is preferably used according to the characteristics. The hose material is preferably soft vinyl chloride. The gun nozzle material is also preferably polypropylene as the reinforced plastic.
Further, the high-grade urea water transfer device comprising the high-density polyethylene IBC tank used in the high-grade urea water supply method of the present invention is the upper tank or lower part of the simple high-quality urea water supply device according to the first aspect. The material is the same, only the actual capacity is different from the tank. Actually, it is only necessary to transfer 1000 L of actual high-quality urea water. For example, IBC made of high-density polyethylene having an actual capacity of 1050 to 1500 L is used.
