Description

本発明は、バイオマス等の有機燃料を用いた有機燃料ガス化発電システム及び方法に関する。   The present invention relates to an organic fuel gasification power generation system and method using an organic fuel such as biomass.

一般にバイオマスとは、エネルギー源または工業原料として利用することのできる生物体（例えば、農業生産物または副産物、木材、植物等）をいい、太陽エネルギー、空気、水、土壌等の作用により生成されるので、無限に再生可能である。   Biomass generally refers to organisms that can be used as energy sources or industrial raw materials (for example, agricultural products or by-products, wood, plants, etc.), and are produced by the action of solar energy, air, water, soil, etc. So it can be played indefinitely.

上記バイオマスをガス化燃料として利用することで燃料用のガス及びメタノール等のクリーンなエネルギー源の製造が可能となる。また、廃棄物としてのバイオマスを処理できるので、環境の浄化にも役立つとともに、新規に生産されるバイオマスも光合成によりＣＯ2の固定により生育される。大気のＣＯ2を増加させないので、ＣＯ2の抑制につながることとなり、好ましい技術である。 By using the biomass as a gasification fuel, it becomes possible to produce clean energy sources such as fuel gas and methanol. Further, since biomass as waste can be treated, it is useful for environmental purification, and newly produced biomass is also grown by fixing CO 2 by photosynthesis. Since it does not increase CO 2 in the atmosphere, it leads to suppression of CO 2 , which is a preferable technique.

ここで、供給するバイオマスとしては、生産または廃棄されたバイオマスを粉砕・乾燥したものを供給するのが好ましい。本発明でバイオマスとは、エネルギー源または工業原料として利用することのできる生物資源（例えば、農業生産物または副産物、木材、植物等）をいい、例えば、スイートソルガム，ネピアグラス，スピルリナ等が用いられている（特許文献１及び特許文献２、非特許文献１）。   Here, as the biomass to be supplied, it is preferable to supply pulverized and dried biomass produced or discarded. In the present invention, the biomass means a biological resource (for example, agricultural product or by-product, wood, plant, etc.) that can be used as an energy source or an industrial raw material. For example, sweet sorghum, napier grass, spirulina, etc. are used. (Patent Document 1, Patent Document 2, and Non-Patent Document 1).

ところで、バイオマス原料はその性質上、高水分であり、そのまま用いるとプラント効率が著しく低下すると共に、そのハンドリングも困難である、という問題がある。   By the way, the biomass raw material has a high moisture content, and there is a problem that if it is used as it is, the plant efficiency is remarkably lowered and its handling is difficult.

このため、水分を除去するために例えば天日乾燥する場合には、膨大な敷地面積を必要とし、またバイオマスの種類によっては、その乾燥の際に悪臭を発生する、という問題がある。   For this reason, in order to remove moisture, for example, when drying in the sun, there is a problem that an enormous site area is required, and depending on the type of biomass, malodor is generated during the drying.

そこで、バイオマスを乾燥器により乾燥させ、その乾燥空気をバイオマスガス化炉の酸化剤として利用することを試みたが、その乾燥の際に取り込まれる水分がバイオマスガス化ガス中に存在することとなり、ガス精製装置での排水の際にタール成分等の重質分の臭気が発生するという問題があり、ガス精製の際の無排水化を図ることが切望されている。   Therefore, we tried to dry the biomass with a dryer and use the dry air as an oxidant for the biomass gasification furnace, but the moisture taken in during the drying will be present in the biomass gasification gas, There is a problem that a heavy odor such as a tar component is generated during drainage in a gas purifier, and there is an urgent need to eliminate drainage during gas purification.

本発明は、前記問題に鑑み、バイオマス等の有機燃料を効率的に乾燥することができると共に、生成ガスの無排水化を図ったバイオマス等の有機燃料を用いた有機燃料ガス化発電システム及び方法を提供することを課題とする。   In view of the above problems, the present invention can efficiently dry organic fuel such as biomass, and also uses an organic fuel gasification power generation system and method using an organic fuel such as biomass in which generated gas is not drained. It is an issue to provide.

以下、この発明につき図面を参照しつつ詳細に説明する。なお、この実施例によりこの発明が限定されるものではない。また、下記実施例における構成要素には、当業者が容易に想定できるもの、あるいは実質的に同一のものが含まれる。   Hereinafter, the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same.

本発明による実施例に係る有機燃料ガス化発電システムについて、図面を参照して説明する。図１は、実施例に係る有機燃料ガス化発電システムを示す概念図である。
図１に示すように、本実施例に係る有機燃料ガス化発電システム１０は、例えば有機燃料であるバイオマス１１を乾燥する乾燥器１２と、前記乾燥したバイオマスをラインＬ1により供給して粉砕する粉砕器１３と、前記粉砕器１３で粉砕されたバイオマスをガス化するバイオマスガス化炉１４と、前記バイオマスガス化炉１４で生成された生成ガス１５を生成ガス供給ラインＬ2により供給して熱交換する熱交換器１６と、前記熱交換後の生成ガス中の不純物を除去するガス精製装置１７と、前記精製ガスを用いて発電して電力を得る例えばガスエンジン、ガスタービン等の発電装置１８と、前記発電装置１８からの排ガスを乾燥器１２に供給するガス供給ラインＬ3と、前記乾燥器１２に供給したバイオマスガス化炉１４の酸化剤である空気２０中の煤塵を除去する除塵器２１と、前記除塵された後の空気２０中の水分を凝縮する冷却器２２とを介装してなる酸化剤供給ラインＬ4とを具備するものである。
本発明でバイオマスとは、エネルギー源又は工業原料として利用することのできる生物資源（例えば農業生産物又は副産物、木材、植物等）をいい、例えばスイートソルガム，ネピアグラス，スピルリナ等を例示することができる。また、糠、木くず、間伐材等の農林系廃棄物も含まれる。 An organic fuel gasification power generation system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram illustrating an organic fuel gasification power generation system according to an embodiment.
As shown in FIG. 1, an organic fuel gasification power generation system 10 according to the present embodiment includes, for example, a dryer 12 that dries biomass 11 that is organic fuel, and supplies the dried biomass through a line L 1 for pulverization. A pulverizer 13, a biomass gasification furnace 14 for gasifying the biomass pulverized by the pulverizer 13, and a generated gas 15 generated in the biomass gasification furnace 14 are supplied through a generated gas supply line L 2 and heated. A heat exchanger 16 to be exchanged, a gas purification device 17 for removing impurities in the product gas after the heat exchange, and a power generation device 18 such as a gas engine or a gas turbine for generating electric power using the purified gas. When the exhaust gas with the gas supply line L 3 to be supplied to the dryer 12 from the power generating device 18, an oxidation agent of the dryer 12 biomass gasifier 14 that is supplied to the air A dust collector 21 for removing dust in 20, and includes an oxidant supply line L 4, which is interposed a condenser 22 formed by condensing the moisture in the air 20 after the being dust.
Biomass in the present invention refers to biological resources that can be used as an energy source or industrial raw material (for example, agricultural products or by-products, wood, plants, etc.), and examples include sweet sorghum, napiergrass, spirulina, and the like. it can. It also includes agricultural and forestry waste such as firewood, wood scrap, and thinned wood.

本実施例では、酸化剤として導入する空気２０は、前記乾燥器１２中を通過させることで予熱し、その後空気中の２３を除去する除塵器２１を通過し除去し、次いで冷却器で空気中の水分を排水２４として除去するようにしている。また、前記発電装置１８からの排ガス１９を乾燥器１２に導入して乾燥器１２の熱源として熱の有効利用を図るようにしている。   In this embodiment, the air 20 introduced as an oxidant is preheated by passing through the dryer 12 and then removed by passing through a dust remover 21 that removes 23 in the air. The water is removed as drainage 24. Further, the exhaust gas 19 from the power generation device 18 is introduced into the dryer 12 so as to effectively use heat as a heat source of the dryer 12.

この結果、発電装置１８の排ガス１９の熱を有効利用することができると共に、酸化剤としてバイオマスガス化炉１４に供給する空気を乾燥に用いる際に、水分が含まれるがその水分を冷却器２２で除去することで、バイオマスガス化炉１４に持ち込む水分量を大幅に低減させることができる。
この結果、バイオマスガス化炉のガス化効率が向上すると共に、生成ガス中においても水分の低減を図ることができ、ガス精製装置１７においても無排水化を行なうことができる。 As a result, the heat of the exhaust gas 19 of the power generation device 18 can be used effectively, and when air supplied to the biomass gasification furnace 14 as an oxidizer is used for drying, the moisture is contained in the cooler 22. The amount of water brought into the biomass gasification furnace 14 can be significantly reduced by removing the water.
As a result, the gasification efficiency of the biomass gasification furnace is improved, moisture can be reduced even in the generated gas, and no drainage can be performed in the gas purification device 17.

すなわち、前記乾燥器１２でバイオマス１１の乾燥を行なった空気２０は、水分が４０〜５０％程度含まれているので、そのままバイオマスガス化炉１４に供給すると、ガス化効率が大幅に低下することとなる。   That is, since the air 20 that has dried the biomass 11 in the dryer 12 contains about 40 to 50% of moisture, if it is supplied to the biomass gasification furnace 14 as it is, the gasification efficiency is greatly reduced. It becomes.

これに対し、本発明では、酸化剤供給ラインＬ4に介装された除塵器２１で先ず、空気中の微粉２３を除去した後、冷却器２２で冷却することで水分濃度を２０％以下、好ましくは１０％以下とすることで、ガス化効率の向上を図るようにしている。 On the other hand, in the present invention, after removing the fine powder 23 in the air with the dust remover 21 interposed in the oxidant supply line L 4 , the moisture concentration is 20% or less by cooling with the cooler 22. Preferably, the gasification efficiency is improved by setting it to 10% or less.

また、前記冷却器２２での水分除去に先立って除塵器２１で空気２０中の微粉２３を除去しているので、冷却器２２での冷却による排水中の汚染防止を図ることができる。   Further, since the fine powder 23 in the air 20 is removed by the dust remover 21 prior to the water removal by the cooler 22, it is possible to prevent contamination in the drainage by cooling with the cooler 22.

これにより、バイオマスガス化炉１４でのガス化効率が向上（約１０％の改良）すると共に、生成ガス１５中の水分も極微量となるので、ガス精製装置１７においても無廃水化を図ることができる。   As a result, the gasification efficiency in the biomass gasification furnace 14 is improved (improvement of about 10%), and the amount of water in the product gas 15 is extremely small. Can do.

この結果、バイオマスガス化炉１４に供給する前において酸化剤である空気中の水分が除去される結果、ガス精製装置１７での凝縮水の発生が無く、無排水化がなされ、これにより排水除去の際に伴うタール成分等の重質分の臭気の発生が防止される。   As a result, the moisture in the air, which is an oxidant, is removed before being supplied to the biomass gasification furnace 14, so that no condensed water is generated in the gas purification device 17 and no drainage is performed. Occurrence of heavy odors such as tar components during the process is prevented.

また、前記発電装置１８から発生する排ガス１９は、排熱を有しているので、前記バイオマス１１を乾燥する乾燥器１２に供給することで、有効利用を図ることができる。   Moreover, since the exhaust gas 19 generated from the power generator 18 has exhaust heat, it can be effectively used by supplying the biomass 11 to the dryer 12 for drying.

ここで、排熱の有効利用のためには、前記乾燥装置１２に供給する前記排ガス１９に水を噴霧して排ガスの熱容量を高めて使用するようにしてもよい。   Here, in order to effectively use the exhaust heat, the exhaust gas 19 supplied to the drying device 12 may be sprayed with water to increase the heat capacity of the exhaust gas.

なお、本実施例では、前記酸化剤供給ラインＬ4に、前記乾燥器１２に供給したバイオマスガス化炉１４の酸化剤である空気２０中の煤塵を除去する空気用除塵器２１を介装しているが、微粉を有していない例えば芝等のバイオマスを用いる場合には、前記空気用除塵装置２１を用いる必要がない。 In this embodiment, the oxidant supply line L 4 is provided with an air dust remover 21 that removes dust in the air 20 that is the oxidant of the biomass gasification furnace 14 supplied to the dryer 12. However, when using biomass such as turf which does not have fine powder, it is not necessary to use the air dust removing device 21.

また、図２に示すように、例えば油等の熱媒３１を用いた熱交換器３２を用いて、排ガス１９と熱交換し、熱交換された熱媒３１を乾燥器１２内に供給するようにして間接的にバイオマス１１を乾燥させるようにしてもよい。   Further, as shown in FIG. 2, for example, the heat exchanger 32 using a heat medium 31 such as oil is used to exchange heat with the exhaust gas 19, and the heat medium 31 subjected to heat exchange is supplied into the dryer 12. Thus, the biomass 11 may be indirectly dried.

また、バイオマス１１中の水分が多い場合には、図３に示すように、熱交換器１６で熱交換された余剰の熱を用いて乾燥を行なうようにしてもよい。   Moreover, when there is much water | moisture content in the biomass 11, you may make it dry using the excess heat heat-exchanged with the heat exchanger 16, as shown in FIG.

また、図４に示すように、乾燥器１２に供給するバイオマス１１中の微粉２３を例えばサイクロン等のバイオマス用の除塵装置３５で除去することにより、図１に示すような水分を含む空気から微粉２３を除去する必要がなくなる。   Moreover, as shown in FIG. 4, the fine powder 23 in the biomass 11 supplied to the dryer 12 is removed by a dust removing device 35 for biomass such as a cyclone, so that the fine powder is removed from the moisture-containing air as shown in FIG. 23 need not be removed.

ここで、本実施例では、粉砕器１３を用いて所定のガス化に適した粒径にバイオマスを粉砕しているが、予め所定粒径に粉砕されたバイオマスを用いる場合には不要である。   Here, in this embodiment, biomass is pulverized to a particle size suitable for predetermined gasification using the pulverizer 13, but this is not necessary when using biomass pulverized in advance to a predetermined particle size.

以上のように、本発明によれば、バイオマス等の有機燃料を効率的に乾燥することができると共に、生成ガスの無排水化を図ることができる。   As described above, according to the present invention, organic fuel such as biomass can be efficiently dried, and the generated gas can be drained.
