Description

本発明は、建物の冷暖房装置や分散型電源用原動機から排出される排気ガスを、ガス清浄装置を介して、閉鎖型の植物育生設備に供給する排気ガス供給植物育生システムに関するものである。   The present invention relates to an exhaust gas supply plant breeding system that supplies exhaust gas discharged from a building air conditioner or a distributed power source prime mover to a closed plant breeding facility via a gas cleaning device.

従来、図１に示すように、建物Ｂの冷暖房装置１からは、大量の二酸化炭素と排熱が大気中に放出されている。また、近年では、電力市場の自由化に伴い、図２に示すように、ディーゼルエンジン、ガスエンジンあるいはガスタービンといった分散型電源用原動機２による発電が多くの工場やホテル等で行われており、その原動機２からも大量の二酸化炭素と排熱が放出されている。   Conventionally, as shown in FIG. 1, a large amount of carbon dioxide and exhaust heat are released from the air conditioner 1 of a building B into the atmosphere. Moreover, in recent years, with the liberalization of the electric power market, as shown in FIG. 2, power generation by the distributed power source prime mover 2 such as a diesel engine, a gas engine or a gas turbine is performed in many factories and hotels, A large amount of carbon dioxide and exhaust heat are also released from the prime mover 2.

この大気中に大量に放出される二酸化炭素等の影響で、ヒートアイランド現象等の環境汚染が進んでおり、近年、これを抑制するために、建物Ｂの屋上に草木を繁茂させる緑化設備２０を設けるといった方策が講じられている。   Environmental pollution such as the heat island phenomenon has progressed under the influence of carbon dioxide released in large quantities into the atmosphere. In recent years, a greening facility 20 for planting vegetation is provided on the roof of the building B. The following measures are taken.

しかし、一旦、大気中に放出された二酸化炭素は、大気の流れに従って長い時間対流し、その後、その一部が緑化設備２０の植物に吸収されるのであり、大部分は大気中に残存し、これが環境汚染の原因となる。   However, once the carbon dioxide released into the atmosphere convects for a long time according to the atmospheric flow, a part of it is absorbed by the plant of the greening facility 20, and most of it remains in the atmosphere. This causes environmental pollution.

本発明は、こうした点に鑑み創案されたもので、冷暖房装置や分散型電源用原動機から放出される二酸化炭素を含む排気ガスを、緑化設備を初めとする植物育生設備に効果的に供給して、環境汚染を抑制し、かつ、植物の育生を促すことのできる排気ガス供給植物育生システムを提供することを課題とする。   The present invention has been devised in view of these points, and effectively supplies exhaust gas containing carbon dioxide released from an air conditioner or a power generator for a distributed power source to plant growth facilities such as a greening facility. Another object of the present invention is to provide an exhaust gas supply plant breeding system that can suppress environmental pollution and promote plant breeding.

Since it is connected to the closed plant growth facility 3, the carbon dioxide and exhaust heat in the exhaust gas discharged from the air conditioner 1 and the like are directly supplied to the plant growth facility 3 without being released into the atmosphere. can do. Thereby, while being able to promote the growth of a plant, environmental pollution can be suppressed.

請求項２に記載の発明は、ガス清浄装置５を、アンモニアタンク７に連結した混合機ユニット６と、触媒ユニット８と、酸素タンク１０に連結した脱酸ユニット９とで構成しているので、排気ガスに含まれる植物に有害な物質を効果的に除去し、植物の生育に必要な二酸化炭素を植物育生設備３に効果的に供給することができる。   Since the invention according to claim 2 comprises the gas cleaning device 5 by the mixer unit 6 connected to the ammonia tank 7, the catalyst unit 8, and the deoxidation unit 9 connected to the oxygen tank 10, Substances harmful to plants contained in the exhaust gas can be effectively removed, and carbon dioxide necessary for plant growth can be effectively supplied to the plant growth facility 3.

すなわち、排気ガスを、高温下における混合機ユニット６でアンモニアガスと化合させて、それに含まれる窒素酸化物（ＮＯＸ）をアンモニアと二酸化炭素に分解する。次に、触媒ユニット８において、窒素ガスと水に分解する。そして、脱酸ユニット９において酸素と接触させ、それに含まれるエチレンガス（Ｃ２Ｈ４）を二酸化炭素と水に分解する。こうして、有害物質を除去し、二酸化炭素を植物育生設備３に供給する。 That is, the exhaust gas is combined with ammonia gas in the mixer unit 6 at a high temperature, and the nitrogen oxide (NO x ) contained therein is decomposed into ammonia and carbon dioxide. Next, the catalyst unit 8 is decomposed into nitrogen gas and water. Then, the deoxidation unit 9 is brought into contact with oxygen, and the ethylene gas (C 2 H 4 ) contained therein is decomposed into carbon dioxide and water. In this way, harmful substances are removed and carbon dioxide is supplied to the plant growth facility 3.

本発明に係る排気ガス供給植物育生システムの第一実施形態を、図３および図４に示す。これは、建物Ｂの冷暖房装置１から排出される排気ガスに含まれる二酸化炭素および排熱を、当該建物Ｂの屋上に設けた閉鎖型の植物育生設備３に供給するシステムである。この植物育生設備３は、草木を繁茂させた緑化設備である。   3 and 4 show a first embodiment of an exhaust gas supply plant breeding system according to the present invention. This is a system that supplies carbon dioxide and exhaust heat contained in the exhaust gas discharged from the cooling / heating device 1 of the building B to the closed plant growth facility 3 provided on the roof of the building B. This plant growth facility 3 is a planting facility in which vegetation is grown.

このシステムは、冷暖房装置１から延出された排気ダクト４を、ガス清浄装置５を介して、植物育生設備３に接続している。ガス清浄装置５は、排気ガス中に含まれる植物に有害な物質を除去するはたらきを行うもので、アンモニアタンク７に連結した混合機ユニット６と、触媒ユニット８と、酸素タンク１０に連結した脱酸ユニット９とで構成される。   In this system, an exhaust duct 4 extended from an air conditioner 1 is connected to a plant breeding facility 3 via a gas purifier 5. The gas purifier 5 serves to remove substances harmful to plants contained in the exhaust gas. The gas purifier 5 is a mixer unit 6 connected to the ammonia tank 7, a catalyst unit 8, and a desorber connected to the oxygen tank 10. It is comprised with the acid unit 9.

当該排気ガス供給植物育生システムは、冷暖房装置１から排出される排気ガスを、ガス清浄装置５によって植物の生育に有害な物質を除去し、植物の生育に必要な二酸化炭素を植物育生設備３に供給するので、植物の生育を効果的に促すことができる。   The exhaust gas supply plant breeding system removes substances harmful to the growth of plants from the exhaust gas discharged from the air conditioner 1 by the gas cleaning device 5 and supplies carbon dioxide necessary for the growth of plants to the plant breeding equipment 3. Since it supplies, the growth of a plant can be promoted effectively.

すなわち、冷暖房装置１から排出される排気ガスを、高温下において、混合機ユニット６でアンモニアタンク７から供給されるアンモニアガスと化合させて、それに含まれる窒素酸化物（ＮＯＸ）をアンモニアと二酸化炭素に分解する。次に、続く触媒ユニット８において、窒素ガスと水に分解する。そしてさらに、脱酸ユニット９において酸素と接触させ、エチレンガス（Ｃ２Ｈ４）を二酸化炭素と水（Ｈ２Ｏ）に分解する。こうすることによって、排気ガスから有害物質を除去し、植物に有益な二酸化炭素を植物育生設備３に供給する。   That is, the exhaust gas discharged from the air conditioner 1 is combined with the ammonia gas supplied from the ammonia tank 7 by the mixer unit 6 at a high temperature, and the nitrogen oxide (NOX) contained therein is combined with ammonia and carbon dioxide. Disassembled into Next, in the subsequent catalyst unit 8, it is decomposed into nitrogen gas and water. Further, the deoxidation unit 9 is brought into contact with oxygen to decompose ethylene gas (C2H4) into carbon dioxide and water (H2O). In this way, harmful substances are removed from the exhaust gas, and carbon dioxide useful for plants is supplied to the plant breeding facility 3.

また、このシステムは、冷暖房装置１から排出される排気ガスをそのまま大気中に放出するのではなく、植物育生設備３を通して放出するので、放出される二酸化炭素の量を大幅に削減することができる。従って、環境汚染を抑制することができる。   In addition, this system does not directly release the exhaust gas discharged from the air conditioner 1 into the atmosphere, but releases it through the plant breeding facility 3, so that the amount of carbon dioxide released can be greatly reduced. . Therefore, environmental pollution can be suppressed.

本発明に係る排気ガス供給植物育生システムの第二実施形態を、図５および図６に示す。このシステムの特徴は、分散型電源用原動機２から排出される排気ガスを利用していることである。当該原動機２から排出される排気ガスは、通常、１５０℃以上の高温であるため、そのまま閉鎖型の植物育生設備３に供給することはできない。そのため、ガス清浄装置５に熱交換器１１を加え、当該熱交換器１１で５０℃以下の適温まで下げた後、植物育生設備３に供給する。これにより、植物の生育をより促進することができる。   5 and 6 show a second embodiment of the exhaust gas supply plant breeding system according to the present invention. A feature of this system is that it uses exhaust gas discharged from the distributed power prime mover 2. Since the exhaust gas discharged from the prime mover 2 is usually at a high temperature of 150 ° C. or higher, it cannot be supplied to the closed plant growth facility 3 as it is. Therefore, the heat exchanger 11 is added to the gas cleaning device 5, the temperature is lowered to an appropriate temperature of 50 ° C. or less by the heat exchanger 11, and then supplied to the plant growth facility 3. Thereby, growth of a plant can be promoted more.

なお、冷暖房装置１から排出される排気ガスを利用したシステム（図３）に、熱交換器１１を備えたガス清浄装置５（図６）を加えると、当該熱交換器１１によって、排熱を植物の生育に必要な温度に設定した後、植物育生設備３に供給することができる。従って、植物の育生をさらに促すことができる。   In addition, if the gas cleaning apparatus 5 (FIG. 6) provided with the heat exchanger 11 is added to the system (FIG. 3) using the exhaust gas discharged | emitted from the air conditioning apparatus 1, waste heat will be exhausted by the said heat exchanger 11. After setting the temperature necessary for the growth of the plant, it can be supplied to the plant growth facility 3. Therefore, it is possible to further promote plant growth.

本発明に係る排気ガス供給植物育生システムは、緑化を目的とする草木の育生のみでなく、メロンやトマト等といった農産品の周年栽培にも適用することができる。   The exhaust gas supply plant breeding system according to the present invention can be applied not only to the cultivation of vegetation for the purpose of greening, but also to the annual cultivation of agricultural products such as melons and tomatoes.
