Description

明 細 書 排ガス浄化装置 技術分野  Description Exhaust gas purification equipment Technical field
本発明は、 燃焼装置の排気ガスを浄化することにより、 大気中に有害物質が排 出されるのを防止して、 排ガス汚染を改善する排ガス浄化装置に係る。 背景技術  The present invention relates to an exhaust gas purifying apparatus that purifies exhaust gas from a combustion apparatus, thereby preventing harmful substances from being discharged into the atmosphere, and improving exhaust gas pollution. Background art
一般に、 ガソリンや軽油等の炭化水素を利用して動力を発生する内燃機関は、 完全燃焼が困難であるため、 その稼動によって種々の未燃成分や高温燃焼成分な どが含まれたガスが大気中に排出されることとなる。 特に、 ディーゼルエンジン は、呼吸器疾患の原因とされる浮遊粒子状物質(SPM: Su s p ende d P a r t i c u l a t e Ma t t e r )、 窒素酸化物 (NOx)、 硫黄酸化物 (S Ox) などの排出量が多く、 さらに、 酸化や NO Xとの反応でアルデヒド、 ナイ トレート強酸等の有害物質が発生する炭化水素 (HC) なども排出されるため、 排ガス汚染に深刻な影響を与えることとなる。  In general, since internal combustion engines that generate power using hydrocarbons such as gasoline and light oil are difficult to completely burn, gas containing various unburned components and high-temperature combustion components is generated by the operation. Will be discharged inside. In particular, diesel engines emit low amounts of suspended particulate matter (SPM), nitrogen oxides (NOx), and sulfur oxides (SOx), which can cause respiratory illness. In addition, hydrocarbons (HC), which generate harmful substances such as aldehydes and nitrate strong acids due to oxidation and reaction with NOx, are also emitted, which has a serious effect on exhaust gas pollution.
しかしながら、 自動車の中でも、特にディーゼル車は、 ガソリン車と比較して、 燃料 (軽油) が安価でエネルギー効率が良く且つその耐用年数が極めて長いとい う利点がある。 よって、 ディーゼルエンジンは、 上記のような排ガス汚染への影 響にも関わらず、 トラックやバスなどの大型車用のエンジンとして数多く採用さ れており、 産業分野の多方面に亘つてその利用台数は年々増加しているのが現状 である。  However, among automobiles, diesel cars in particular have the advantage that fuel (light oil) is inexpensive, energy efficient, and their service life is extremely long compared to gasoline cars. Therefore, despite their impact on exhaust gas pollution, diesel engines are widely used as engines for large vehicles such as trucks and buses, and the number of diesel engines used in various fields in the industrial field has been increasing. Is increasing year by year.
このような状況下で、 排ガス汚染が社会問題にまで至ったことから、 各国で排 出ガス規制が行われ、 特にその主要な発生源として指摘されたディ一ゼル車によ る排ガス対策として、 業務用ディ一ゼル車のガソリン車への代替ゃ排ガス浄化装 置の装着などが推進されていた。  Under such circumstances, exhaust gas pollution has become a social problem, and exhaust gas regulations have been implemented in various countries.Especially as a measure to reduce exhaust gas by diesel vehicles, which has been pointed out as a major source, Replacement of commercial diesel vehicles with gasoline vehicles and installation of exhaust gas purification equipment were being promoted.
ここで、 業務用ディーゼル車のガソリン車への代替とは、 ディーゼル車数自体 を減少させることによって、 有害物質の排出量を抜本的に削減しょうとするもの である。 しかし、 コストパフォーマンスなどの要請から、 ガソリン車への代替を 普及させることは非常に困難であり、 現実的といえるものではない。 Here, replacing commercial diesel vehicles with gasoline vehicles means drastically reducing harmful substance emissions by reducing the number of diesel vehicles. It is. However, it is very difficult to spread the alternative to gasoline vehicles due to cost performance and other demands, and it is not realistic.
一方、 排ガス浄化装置とは、 一般に、 ディーゼル車の排ガス中の浮遊粒子状物 質を除去する装置を指す。 例えば、 マフラーの代わりに取り付けて、 黒煙を最燃 焼し、 浮遊粒子状物質の排出量を約 8割程度削減することによって、 結果的にデ イーゼル車の低公害ィ匕を図ろうとするものである。このような排ガス浄化装置は、 触媒を利用した構造を採用すると、 約 2 0万円程度で生産することができる。 しかし、 このような排ガス浄ィ匕装置の構造によると、 ディーゼル車の燃料の軽 油中に含まれる硫黄によって、 排ガス浄化装置 (D P F) 自体の金属部分が腐食 してしまうため、 実用化に際しては非常に高価格のセラミック製のものとせざる を得ない。 なお、 硫黄による腐食を防止するために軽油中の硫黄成分を削減する ことも考えられるが、 このような燃料成分の改良には多額な設備投資が必要とな る。  On the other hand, an exhaust gas purification device generally refers to a device that removes suspended particulate matter in exhaust gas from diesel vehicles. For example, installing a muffler instead to burn black smoke to the maximum and reduce the amount of suspended particulate matter by about 80%, resulting in low pollution of diesel vehicles It is. Such an exhaust gas purification device can be manufactured for about 200,000 yen if a structure using a catalyst is adopted. However, according to the structure of such an exhaust gas purifying device, the sulfur contained in the diesel diesel fuel corrodes the metal part of the exhaust gas purifying device (DPF) itself. It must be made of very expensive ceramic. Although it is conceivable to reduce the sulfur component in light oil in order to prevent corrosion due to sulfur, such a fuel component improvement requires a large capital investment.
これに対処するため、排ガスを水や特別な水溶液等の液体に通すことによって、 有害物質を分離、 除去する装置が提案されている。 例えば、 特開平 7 — 1 8 9 6 5 8号公報、 特開平 6— 1 2 3 2 1 7号公報、 特開平 7— 2 2 4 6 3 8号公報に は、 排ガスを液体中で気泡化させることによって、 液体に対する排ガスの接触面 積を大きくして、 排ガス中の S P M、 N O X等を除去する排ガス浄ィ匕装置が開示 されている。  To cope with this, a device has been proposed to separate and remove harmful substances by passing exhaust gas through liquids such as water and special aqueous solutions. For example, Japanese Patent Application Laid-Open Nos. 7-189658 / 1994, 6-12 / 32/17 and 7-224648 / 1994 disclose that exhaust gas is bubbled in a liquid. An exhaust gas purifying apparatus that removes SPM, NOX, and the like in the exhaust gas by increasing the contact area of the exhaust gas with the liquid by performing the operation is disclosed.
しかしながら、 特開平 7— 1 8 9 6 5 8号公報ゃ特開平 6— 1 2 3 2 1 7号公 報に開示された排ガス浄化装置は、 有害物質のうち S P Mを含む粉塵等の分離回 収は可能であっても、 他の有害物質である N〇x、 S O x、 H C等に対する除去 能力は十分ではない。 一方、 特開平 7— 2 2 4 6 3 8号公報に開示された排ガス 浄化装置は、 N O x、 S O xの除去は可能であるが、 特別な水溶液を用いる必要 があるので、 取扱いが面倒であり、 維持管理にコストがかかる。 さらに、 両者を 単純に組み合わせたとしても、 特別な水溶液を用いる限り、 取扱いの困難性は残 る。  However, the exhaust gas purifying apparatus disclosed in Japanese Patent Application Laid-Open No. 7-189658 / 1994 and Japanese Patent Application Laid-Open No. 6-123217 separates and collects harmful substances such as dust containing SPM. Is possible, but its ability to remove other harmful substances such as N〇x, SOx, and HC is not sufficient. On the other hand, the exhaust gas purifying apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 7-224648 can remove NOx and SOx, but requires the use of a special aqueous solution, and is therefore troublesome to handle. Yes, maintenance costs are high. Furthermore, even if the two are simply combined, handling remains difficult as long as a special aqueous solution is used.
このように、 ディーゼル車に対する実用的で有効な排ガス対策が見つからない にも関わらず、 特に大都市圏での交通量は増大する一方であるため、 排ガス汚染 はますます深刻な状況に至っていた。 In spite of the fact that no practical and effective emission control measures for diesel vehicles have been found, the traffic volume, especially in metropolitan areas, is increasing. Had come to an increasingly serious situation.
本発明は、 以上のような従来技術の問題点を解決するために提案されたもので あり、 安価且つ簡易な構成で、 種々の有害物質の排出量を確実且つ効率的に削減 することができ、 取扱いが容易な排ガス浄化装置を提供することにより、 早急に 排ガス汚染を改善し、 環境保護に資することを目的とする。 発明の開示  The present invention has been proposed in order to solve the above-mentioned problems of the prior art, and it is possible to reliably and efficiently reduce the emission of various harmful substances with an inexpensive and simple configuration. The aim is to improve exhaust gas pollution promptly and contribute to environmental protection by providing easy-to-handle exhaust gas purification equipment. Disclosure of the invention
本発明の排ガス浄化装置は、 上記の目的を達成するために、 内部に水を封入し たタンクと、燃焼装置からの排ガスを、前記タンク内の水中に送り込む連結管と、 前記タンク内の水中に配置され、 前記排ガスを中和する石灰石と、 前記タンク内 の水中に配置され、 前記排ガスの気泡を小さくする網部と、 前記タンクと外部を 連通する排気筒とを備えたことを特徴とする。  In order to achieve the above object, an exhaust gas purifying apparatus of the present invention includes a tank in which water is sealed, a connecting pipe for sending exhaust gas from a combustion device into the water in the tank, and a water pipe in the tank. A limestone that is disposed in the tank and neutralizes the exhaust gas, a net portion that is disposed in water in the tank and reduces bubbles of the exhaust gas, and an exhaust pipe that communicates the tank with the outside. I do.
以上のような本発明によれば、 燃焼装置からの排ガスが、 連結管から水中に送 りこまれ、 強酸性の NO Xや S O X等の有害物質が、 アル力リ性の石灰石に接触 して中和、 除去される。 さらに、 排ガスが網部を通過する際に、 気泡が細かくな り水との接触面積が大きくなるので、 排ガス中の S P M等の粉塵が効率良く水中 に捕捉される。 浄化された排ガスは、 排気筒を介して外部へ排出される。  According to the present invention as described above, the exhaust gas from the combustion device is sent into the water from the connecting pipe, and harmful substances such as strongly acidic NO X and SOX come in contact with the alkaline limestone and become harmful. Sum, removed. Furthermore, when the exhaust gas passes through the mesh, the bubbles become finer and the contact area with water increases, so that dust such as SPM in the exhaust gas is efficiently captured in the water. The purified exhaust gas is discharged to the outside via the exhaust stack.
また、 網部を、 目の粗い第 1の網と、 排ガスにより振動する目の細かい第 2の 網とを有する構成とすれば、 目の細かい第 2の金網の振動によって、 水と排ガス との接触が促進され、 粒子状物質をより効率良く捕捉することができる。  In addition, if the net has a first mesh having a coarse mesh and a second mesh having a fine mesh vibrating due to exhaust gas, the vibration of the second metal mesh having a fine mesh allows water and exhaust gas to be separated. Contact is promoted and particulate matter can be trapped more efficiently.
また、 タンクの内底部に活性炭を配設することによって、 水中へ捕捉された S P M等の粉塵を吸着させることができる。  In addition, by arranging activated carbon on the inner bottom of the tank, dust such as SPM captured in water can be adsorbed.
また、 排気筒に活性炭フィルターを接続することによって、 排気に残留する有 害物質を捕捉することができる。  By connecting an activated carbon filter to the exhaust stack, harmful substances remaining in the exhaust can be captured.
また、タンク内を複数の区画に分ける隔壁板を設けることによって、車の発進、 停止の際に水の浪打ちが防止される。 図面の簡単な説明  In addition, by providing a partition plate that divides the inside of the tank into a plurality of compartments, it is possible to prevent water from being swamped when the vehicle starts and stops. BRIEF DESCRIPTION OF THE FIGURES

( 2 ) 実施の形態の作用  (2) Operation of the embodiment
本発明の排ガス浄化装置は、 一例として前記のような構成を有し、 内燃機関 A の排気口から排出された排ガスを連結管 2によってタンク 1内へ導入し、 これを 排気筒 3から大気中へ排出するものである。 以下にその詳細を説明する。  The exhaust gas purifying apparatus of the present invention has the above-described configuration as an example. To be discharged to The details will be described below.
すなわち、 内燃機関 Aの排気口から連結管 2へ排出された排ガスは、 タンク 1 内の底部に配置された連結管 2の多数の排気穴 2 a力、ら、 タンク 1内の水 9の中 へ排出され、 石灰石 4に対して吹き付けられる。 すると、 アルカリ性の石灰石 4 によって、 強酸性の排気ガスが反応して中和される。 このとき、 石灰石 4の中の 酸化カルシウム ( C a O) と水とが反応して水酸化力ルシゥム (C a (OH) 2) ができ、 N O x、 S O x等の有害物質は、 この C a (OH) 2と反応することに よって、 排ガス中から除去される。 That is, the exhaust gas discharged from the exhaust port of the internal combustion engine A to the connecting pipe 2 is discharged from the many exhaust holes 2a of the connecting pipe 2 arranged at the bottom of the tank 1 and the water 9 in the tank 1. And is sprayed against limestone 4. Then, the strongly acidic exhaust gas reacts and is neutralized by the alkaline limestone 4. At this time, calcium oxide (C a O) in the limestone 4 reacts with water to form a hydroxide hydroxide (C a (OH) 2 ), and harmful substances such as NO x and SO x a Removed from exhaust gas by reacting with (OH) 2 .
例えば、 二酸化窒素 (N 02) が水酸化カルシウム (C a (OH) 2) と反応し て、 中性の硝酸カルシウム (C a (N 03) 2) となる式を、 以下に示す。 C a (OH) 2+ 2N02+ 1/202→C a (N〇3) 2 + H20 …式 1 また、 例えば、 二酸化硫黄 (S02) が水酸化カルシウム (Ca (OH) 2) と 反応して、 亜硫酸カルシウム (CaSO となる式を、 以下に示す。 For example, reacts with nitrogen dioxide (N 0 2) calcium hydroxide (C a (OH) 2) , an expression that the calcium nitrate neutral (C a (N 0 3) 2), shown below. C a (OH) 2 + 2N0 2 + 1/20 2 → C a ( N_〇 3) 2 + H 2 0 ... Formula 1 Further, for example, sulfur dioxide (S0 2) is calcium hydroxide (Ca (OH) 2 ) To react with calcium sulfite (CaSO) is shown below.
Ca (OH) 2+S02→C a S03+H20 …式 2 そして、 排ガスがタンク 1内を上昇すると、 目の粗い第 1の金網 6 aの網目を 通ることによつて気泡が小さくなり、水 9と排ガスの接触面積が大きくなるので、 水 9によって SPM等の粉塵が効率良く捕捉される。 さらに、 排ガスが、 折り曲 げた目の細かい第 2の金網 6 bを通過する際には、 第 2の金網 6 bが振動するの で、 水 9と排ガスとの接触がより一層促進され、 SPM等の粉塵の捕捉効果が増 す。 Ca (OH) 2 + S0 2 → C a S0 3 + H 2 0… Equation 2 Then, when the exhaust gas rises in the tank 1, bubbles are generated by passing through the mesh of the coarse first wire mesh 6a. Since the water becomes smaller and the contact area between the water 9 and the exhaust gas increases, dust such as SPM is efficiently captured by the water 9. Further, when the exhaust gas passes through the bent second wire mesh 6b, the second wire mesh 6b vibrates, so that the contact between the water 9 and the exhaust gas is further promoted, and the SPM The effect of trapping dust and the like increases.
次に、 排ガスは、 水 9の中から空間部 8へと移動し、 排気筒 3から活性炭フィ ルター 11内を通過する際に、 残留する有害物質が捕捉されて、 大気中へ排出さ れる。 一方、 水 9に捕捉された SPMなどの粉塵は、 排ガスの気泡で水 9が攪拌 されることによって、 タンク 1の底部に配置された活性炭 5の多数の細孔に吸着 される。  Next, the exhaust gas moves from the water 9 to the space portion 8, and when passing through the activated carbon filter 11 from the exhaust stack 3, the remaining harmful substances are captured and discharged to the atmosphere. On the other hand, dust such as SPM trapped in the water 9 is adsorbed on a large number of pores of the activated carbon 5 arranged at the bottom of the tank 1 by stirring the water 9 with bubbles of exhaust gas.
そして、 このように有害物質が溶け込んだ水 9は、 排水口 l bから排出され、 図示しない処理装置によって処理されるとともに、 新たに新鮮な水が吸水口 1 a からタンク 1内へ補給される。 また、 SPMなどの粉塵や反応により生成された 物質等が付着、 吸着した石灰石 4や活性炭 5は、 その汚れ具合に応じて適度に交 換される。  Then, the water 9 in which the harmful substances are dissolved is discharged from the drain port lb, is treated by a treatment device (not shown), and fresh water is newly supplied into the tank 1 from the water inlet port 1a. In addition, limestone 4 and activated carbon 5 to which dust such as SPM and substances generated by the reaction are attached and adsorbed are appropriately replaced according to the degree of contamination.
