従来の車両で使用されている排気ガス清浄装置は、排気ガス通路内に触媒を使 った排気ガス清浄部を設けるものである。 この従来の排気ガスの清浄装置は、排気ガスを排気するパイプ・筒体の排気ガ ス通路内に設けられるので、圧損が大きくエンジン・燃焼装置に影響を与えてい た。又、エンジン・燃焼装置に後から清浄装置を取付けることが簡単に出来ない ものであった。 An exhaust gas cleaning device used in a conventional vehicle has an exhaust gas cleaning section that uses a catalyst in the exhaust gas passage. Since this conventional exhaust gas cleaning device is provided in the exhaust gas passage of the pipe / cylindrical body that exhausts the exhaust gas, the pressure loss is large and the engine / combustion device is affected. Moreover, it was not easy to attach a cleaning device to the engine / combustion device later.
【０００３】[0003]
本考案は、従来の装置のこれらの問題点を解消し、エンジン・燃焼装置に影響 を与えずに清浄化でき、又後からエンジン・燃焼装置に取付けることが容易にで き、しかも有効に排気ガス中の汚染ガス成分を除去する排気ガス清浄装置を提供 することにある。 The present invention solves these problems of the conventional device, can be cleaned without affecting the engine / combustion device, and can be easily attached to the engine / combustion device later, and the exhaust gas can be effectively exhausted. An object of the present invention is to provide an exhaust gas cleaning device that removes pollutant gas components in gas.

かかる課題を解決した本考案の要旨は、 １） 排気ガスの排出口に筒体を近接して配置し、筒体の一端開口部を排出口か ら排出される排気ガスの吸入口とし、同筒体内に吸気ファンを設け、同吸気ファ ン後の通気路を水等の液体を貯えた液槽の液中に延伸し、液中下方で通気路を開 放し、液槽の上方空間を吐出口に連通してなる排気ガス清浄装置 ２） 吸気ファンと液槽との間の通気路途中にフィルターを設けた請求項１記載 の排気ガス清浄装置 ３） 液槽の液体がアルカリ性水溶液である請求項１又は２記載の排気ガス清浄 装置 ４） フィルターがアルカリ性である請求項１〜３何れか記載の排気ガス清浄装 置 にある。 本考案の排気ガスは、車両・工場・トンネルいずれの排気ガスにも対応できる 。又、液槽の液体は水・アルカリ水等があり、好ましくはアルカリ水が良い。 The gist of the present invention which has solved such a problem is as follows: 1) A cylinder is disposed in the vicinity of an exhaust gas discharge port, and one end opening of the cylinder is used as an intake port for exhaust gas discharged from the discharge port. An intake fan is installed in the cylinder, and the air passage after the intake fan is extended into the liquid in the liquid tank that stores liquid such as water, and the air passage is opened below the liquid to discharge the space above the liquid tank. An exhaust gas cleaning device communicating with the outlet 2) An exhaust gas cleaning device according to claim 1, wherein a filter is provided in the air passage between the intake fan and the liquid tank 3) The liquid in the liquid tank is an alkaline aqueous solution Item 4. The exhaust gas cleaning device according to claim 1 or 2. 4) The exhaust gas cleaning device according to any one of claims 1 to 3, wherein the filter is alkaline. The exhaust gas of the present invention can be applied to exhaust gas from vehicles, factories and tunnels. The liquid in the liquid tank may be water, alkaline water, etc., preferably alkaline water.
【０００５】[0005]
本考案では、エンジン・燃焼装置の排気ガスは排気口から一旦大気に排出され るが、吸気ファンが作動されていれば吸引力が発生し、排気ガスのかなりの部分 は吸入口から筒体に吸入され、吸気ファンを通過して通気路を経て液槽の中に送 られ、液中下方から気泡となって排出される。排気ガスが液中を気泡となって上 昇する間に液体と接触し、汚染ガスが液に溶解又は反応して除去され、液面から 放出し、吐出口から大気へ吐出される。 In the present invention, the exhaust gas of the engine / combustion device is once discharged to the atmosphere from the exhaust port, but if the intake fan is operated, suction force is generated, and a considerable part of the exhaust gas is transferred from the intake port to the cylinder. It is sucked, passed through the intake fan, sent through the air passage and into the liquid tank, and is discharged as bubbles from below in the liquid. While the exhaust gas forms bubbles in the liquid and rises, it comes into contact with the liquid, dissolves or reacts with the liquid, is removed, is discharged from the liquid surface, and is discharged from the discharge port to the atmosphere.
【０００６】 通気路途中にフィルターがあればこれによっても汚染ガスの一部が除去される 。 上記液槽の液及びフィルターは、水酸化カルシウム・水酸化ナトリウム等の水 溶液の如くアルカリ性であれば汚染ガスの除去は化学反応して炭酸水等になって 効果的に除去できる。If there is a filter in the air passage, this also removes part of the polluted gas. If the liquid and the filter in the liquid tank are alkaline, such as an aqueous solution of calcium hydroxide, sodium hydroxide, etc., the pollutant gas is chemically reacted to form carbonated water, etc., and can be effectively removed.
【０００７】[0007]
以下、本考案の実施例を図面に基づいて説明する。 本実施例はディーゼルトラック１トン車の車両の排気ガスの清浄装置の例であ り、筒体１の吸入口２に煤よけネット３を設け、又フィルター４はアルカリ性の の水酸化カルシウムを含浸させたものを使用し、又液槽５の液体は水酸化カルシ ウム溶液を使用した。又吸気ファン６とフィルター４との間には逆流防止のコー ン７を設けている。 Embodiments of the present invention will be described below with reference to the drawings. This embodiment is an example of a device for cleaning exhaust gas of a vehicle of a 1-ton diesel truck, in which a soot-proof net 3 is provided at an inlet 2 of a cylinder 1, and a filter 4 is made of alkaline calcium hydroxide. The impregnated one was used, and the liquid in the liquid tank 5 was a calcium hydroxide solution. A backflow preventing cone 7 is provided between the intake fan 6 and the filter 4.
【０００８】 図１は実施例の縦断面図、図２は車両への取付状態を示す説明図である。 図中、８は通気路、９は吐出口、１０は液槽５の上部に設けたステンレス製の 金網で、気泡が液面から飛びはねないようにしている。１１は車両の排気ガスを 排出するマフラー、１２は車体、１３は吸気ファン６のモータである。 本実施例の装置を用いて、ディーゼルトラック１トン車でエンジンをスロー回 転状態でのマフラー１１から排出されるＣＯ2の除去の具合を試験した。FIG. 1 is a vertical cross-sectional view of the embodiment, and FIG. 2 is an explanatory view showing a state of attachment to a vehicle. In the figure, 8 is a ventilation path, 9 is a discharge port, and 10 is a metal wire net made of stainless steel provided on the upper part of the liquid tank 5 so that air bubbles do not fly from the liquid surface. Reference numeral 11 is a muffler that discharges exhaust gas from the vehicle, 12 is a vehicle body, and 13 is a motor of the intake fan 6. Using the apparatus of this example, the degree of removal of CO 2 emitted from the muffler 11 was tested in a 1-ton diesel truck with the engine running at slow speed.
【０００９】 マフラー１１から排出される排気ガスをゴミ袋０．０２ｍ3が一杯になるまで 収集する。約４秒かかったが炭酸ガス濃度は２．０％ＶＯＬであった。 これに対し、マフラー１１の後方に実施例の装置を配置し、その吐出口９から 吐出されるガスを同様にゴミ袋０．０２ｍ3が一杯になるまで収集した。The exhaust gas discharged from the muffler 11 is collected until the dust bag 0.02 m 3 is full. It took about 4 seconds, but the carbon dioxide concentration was 2.0% VOL. On the other hand, the device of the embodiment was arranged behind the muffler 11, and the gas discharged from the discharge port 9 was collected in the same manner until 0.02 m 3 of the dust bag was filled.
【００１０】 その結果、ゴミ袋一杯になるまで約３０秒かかったが、ＣＯ2濃度は０．６％ ＶＯＬとなった。４秒にして０．０８％ＶＯＬとなった。又、フィルター４は未 使用時のアルカリ性がｐＨ９．８であった所（フィルターを水で分解して測定す る）、約４時間使用後はｐＨ９．２に、約６時間使用後はｐＨ８．９となった。As a result, it took about 30 seconds to fill the dust bag, but the CO 2 concentration reached 0.6% VOL. It became 0.08% VOL in 4 seconds. Further, when the alkalinity of the filter 4 when not in use was pH 9.8 (measured by decomposing the filter with water), it was adjusted to pH 9.2 after about 4 hours of use and pH 8. 8 after about 6 hours of use. It became 9.
【００１１】 以上の様に、炭酸ガスはフィルター４と液槽５の液によって除去されて、１／ ２５程度に大巾に低下して空気中に再放出された。 尚、吸気ファンによる吸気力は、車種・車両の走行速度によって異なり、フィ ルター４・液槽５を極端に早い流速で通り抜けないようにして、適宜な速度が選 択される。排気ガスの風圧が強い場合によっては吸気ファンを強制回転させない で済ますこともできる。As described above, the carbon dioxide gas was removed by the liquid in the filter 4 and the liquid tank 5, dropped to about 1/25 and re-released in the air. The intake force by the intake fan varies depending on the vehicle type and the traveling speed of the vehicle, and an appropriate speed is selected so as not to pass through the filter 4 and the liquid tank 5 at an extremely high flow rate. In some cases, where the exhaust gas wind pressure is strong, the intake fan may not be forced to rotate.
【００１２】[0012]
以上の様に、本考案によれば、排気ガスを一旦大気に開放したものを吸引して 液槽・フィルターを通過させて汚染ガスを除去するので、エンジン・燃焼装置に 影響を与えずに汚染ガスを除去できる。又、液槽・フィルターで有効に汚染ガス を除去できる。特にアルカリ性とすることによって大巾に汚染ガスを低減できる 。 As described above, according to the present invention, the exhaust gas that has been once opened to the atmosphere is sucked and passed through the liquid tank / filter to remove the pollutant gas, so that the engine / combustor is not polluted. Gas can be removed. Also, the pollutant gas can be effectively removed by the liquid tank / filter. In particular, by making it alkaline, the pollutant gas can be greatly reduced.
