Description
本発明は、木材を原料とした木質燃料の製造方法に関する。 The present invention relates to a method for producing a wood fuel using wood as a raw material.
昨今、建築家屋等の解体に伴って発生する廃木材、製材所等で発生する端材若しくは廃材、又は伐採若しくは剪定により発生する木材等が、木材廃棄物として年間数百万トンの規模で発生している。この木材廃棄物は、近年では、様々な分野でバイオマス燃料としての利用開発が盛んに進められている。主に、バイオマス燃料として、（１）木材を破砕してそのままセメント焼成炉又は発電用ボイラーの燃料の一部として利用したり、（２）木材を炭化して取り扱いやすい燃料に加工して石炭の代替物として利用したり、（３）火力発電所において、木材を数質量％混入させた石炭をミル等で粉砕して、燃料の一部として利用したりしている。 In recent years, waste wood generated by the demolition of architects, scraps or waste materials generated at sawmills, or wood generated by felling or pruning is generated on a scale of several million tons per year as wood waste. is doing. In recent years, the use and development of this wood waste as biomass fuel has been actively promoted in various fields. Mainly used as biomass fuel: (1) Crushing wood and using it directly as part of the fuel for cement firing furnaces or boilers for power generation, or (2) Carbonizing wood to make it easy to handle It is used as an alternative, or (3) In thermal power plants, coal mixed with several mass% of wood is pulverized by a mill or the like and used as part of fuel.
このように木材廃棄物を燃料として活用する場合において、上記（１）においては、木材廃棄物の粒子径が比較的大きいため、完全に燃焼するまでに時間がかかり、また木材廃棄物の粒子径が不均一であるため、例えば、セメント焼成等のような温度コントロールが必要とされる焼成用燃料として、セメント製造装置におけるロータリーキルンの窯前部に投入することはできず、単純に熱量を回収することを主目的として利用するほかはない。また、粒子径の大きな木材廃棄物をセメント製造装置におけるロータリーキルンの窯前部から投入すると、ロータリーキルン内に着底後も木材廃棄物の燃焼が継続するおそれがあり、焼成物（セメントクリンカ）の品質に悪影響を及ぼすという問題がある。 When using wood waste as fuel in this way, in (1) above, the particle size of the wood waste is relatively large, so it takes time to completely burn, and the particle size of the wood waste Is not uniform, for example, it cannot be put into the kiln front of a rotary kiln in a cement production device as a firing fuel that requires temperature control such as cement firing, and simply recovers the amount of heat. There is nothing but to use it as the main purpose. In addition, if wood waste with a large particle size is introduced from the front of the kiln of a rotary kiln in a cement production device, the wood waste may continue to burn after bottoming in the rotary kiln, and the quality of the fired product (cement clinker) There is a problem of adversely affecting.
上記（２）においては、木材廃棄物を炭化することで石炭に近似した性状とすることができ、粉砕性も改善され微粉炭等の代替物としての活用が見込まれるが、木材廃棄物の熱処理の際に緻密な運転管理が必要であり、安全対策の必要性等、製造コストがかかるという問題がある。 In (2) above, charcoalization of wood waste can make it close to coal, and it is expected to be used as an alternative to pulverized coal with improved grindability. In this case, there is a problem that precise operation management is necessary and manufacturing costs are high, such as necessity of safety measures.
上記（３）においては、木材廃棄物の使用量が石炭に対して数質量％ではあるが、発電所等では石炭の使用量が多いため木材廃棄物の使用量も多くなり、廃棄物の有効利用の観点からは好ましい。しかしながら、木材廃棄物の混入量を増加させると、石炭の粉砕に使用しているミルの粉砕能力の低下、粉砕動力の上昇等が確認されており、現状では木材廃棄物の使用量をさらに増加することはできないという問題がある。 In (3) above, the amount of wood waste used is several mass% based on coal. However, the amount of wood waste used in power plants is large, so the amount of wood waste used is also large, and the waste is effectively used. It is preferable from the viewpoint of use. However, increasing the amount of wood waste mixed has been confirmed to decrease the milling capacity of mills used to pulverize coal, increase grinding power, etc., and currently increase the amount of wood waste used. There is a problem that you can not do.
このような実情に鑑みて、本発明は、単純、かつ安全な粉砕処理により、木質原料から燃焼性に優れた取り扱いやすい木質燃料を製造する方法を提供することを目的とする。 In view of such circumstances, an object of the present invention is to provide a method for producing a wood fuel that is excellent in combustibility and easy to handle from a wood raw material by a simple and safe pulverization treatment.
上記課題を解決するために、本発明は、木質原料を粉砕し、最大粒子径を５ｍｍ以下にすることを特徴とする木質燃料の製造方法を提供する（請求項１）。かかる発明（請求項１）によれば、木質原料の粉砕物の最大粒子径を５ｍｍ以下にすることで、取り扱いやすく、かつ燃焼性に優れた木質燃料を製造することができる。 In order to solve the above-mentioned problems, the present invention provides a method for producing a wood fuel, characterized in that a wood raw material is pulverized to have a maximum particle size of 5 mm or less. According to this invention (Invention 1), the maximum particle diameter of the pulverized product of the wood raw material is 5 mm or less, whereby a wood fuel that is easy to handle and excellent in combustibility can be produced.
上記発明（請求項１）においては、前記木質原料を粉砕して得られた粉砕物を分級し、最大粒子径が５ｍｍを超える粉砕物は再度粉砕し、粉砕物の最大粒子径を５ｍｍ以下にすることが好ましい（請求項２）。最大粒子径５ｍｍを超える粉砕物は、燃焼性が悪いため、かかる発明（請求項２）によれば、木質原料を効率的に木質燃料とすることができる。 In the above invention (Invention 1), the pulverized product obtained by pulverizing the wood raw material is classified, and the pulverized product having a maximum particle size exceeding 5 mm is pulverized again, so that the maximum particle size of the pulverized product is 5 mm or less. (Claim 2). Since the pulverized product exceeding the maximum particle diameter of 5 mm has poor combustibility, according to this invention (invention 2), the wood material can be efficiently used as wood fuel.
上記発明（請求項１，２）においては、粉砕機を用いて前記木質原料を粉砕することが好ましい（請求項３）。かかる発明（請求項３）においては、前記粉砕機内に２５０℃以下のガスを通気しながら前記木質原料を粉砕することが好ましい（請求項４）。 In the said invention (invention 1,2), it is preferable to grind | pulverize the said wood raw material using a grinder (invention 3). In this invention (invention 3), it is preferable to pulverize the wood raw material while venting a gas of 250 ° C. or less into the pulverizer (invention 4).
木質原料の含水率が著しく高いと、木質原料を効率的に粉砕できないおそれがあるが、かかる発明（請求項４）によれば、２５０℃以下のガスを通気しながら木質原料を粉砕することで、木質原料を乾燥することができ、木質原料の粉砕効率を向上することができる。 If the moisture content of the wood material is extremely high, the wood material may not be efficiently pulverized. However, according to this invention (invention 4), the wood material is pulverized while a gas of 250 ° C. or less is passed. The wood raw material can be dried, and the pulverization efficiency of the wood raw material can be improved.
上記発明（請求項１〜４）においては、前記木質原料の含水率が、４０質量％以下であることが好ましい（請求項５）。かかる発明（請求項５）によれば、木質原料の含水率が４０質量％であれば、木質原料の粉砕効率をより向上することができる。 In the said invention (invention 1-4), it is preferable that the moisture content of the said wood raw material is 40 mass% or less (invention 5). According to this invention (invention 5), if the moisture content of the wood raw material is 40% by mass, the pulverization efficiency of the wood raw material can be further improved.
本発明によれば、単純、かつ安全な粉砕処理により、木質原料から燃焼性に優れた取り扱いやすい木質燃料を製造する方法を提供することができる。 According to the present invention, it is possible to provide a method for producing an easy-to-handle wood fuel excellent in combustibility from a wood material by a simple and safe pulverization treatment.
本発明の一実施形態に係る木質燃料の製造方法を図面に基づいて説明する。図１は、本実施形態に係る木質燃料の製造方法を示すフロー図である。 The manufacturing method of the wood fuel which concerns on one Embodiment of this invention is demonstrated based on drawing. FIG. 1 is a flowchart showing a method for producing a wood fuel according to the present embodiment.
図１に示すように、本実施形態に係る木質燃料の製造方法においては、まず、原料となる木材（木質原料）を粉砕する。
原料となる木材は、廃棄物であってもよいし、天然木材であってもよく、例えば、建築物解体時に発生する木材廃棄物；製材所より発生する端材又はチップ；伐採木、剪定木等が挙げられる。これらのうち、資源環境問題等を考慮すると、建築解体系木材廃棄物を原料として使用することが好ましい。
As shown in FIG. 1, in the wood fuel manufacturing method according to the present embodiment, first, wood (wood material) as a raw material is pulverized.
The wood used as a raw material may be a waste or a natural wood. For example, wood waste generated at the time of building demolition; scraps or chips generated from a sawmill; felled trees, pruned trees Etc. Among these, it is preferable to use building disassembly system wood waste as a raw material in consideration of resource environment problems and the like.
木質原料の粉砕工程においては、例えば、粉砕機を使用して木質原料を粉砕することができる。木質原料の粉砕に使用する粉砕機としては、例えば、チューブミル、コンパウンドミル、ボールミル等を使用することができ、これらのうちチューブミルを使用することが好ましい。 In the step of pulverizing the wooden raw material, the wooden raw material can be pulverized using, for example, a pulverizer. For example, a tube mill, a compound mill, a ball mill or the like can be used as a pulverizer used for pulverizing the woody raw material. Among these, it is preferable to use a tube mill.
なお、木質原料は、粉砕工程に付する前に、予め破砕機等を使用して最大粒子径を５０ｍｍ以下にしておくことが好ましい。木質原料の最大粒子径を５０ｍｍ以下にしておくことで、最大粒子径５ｍｍ以下の粉砕物の収率を向上させることができ、具体的には、最大粒子径５ｍｍ以下の粉砕物の収率を、５０〜９５％とすることができる。また、粉砕工程における粉砕機にかかる負荷を軽減することができる。 In addition, before attaching | subjecting a wood raw material to a grinding | pulverization process, it is preferable to use a crusher etc. beforehand and to make the maximum particle diameter into 50 mm or less. By setting the maximum particle size of the wood raw material to 50 mm or less, the yield of the pulverized product having a maximum particle size of 5 mm or less can be improved. Specifically, the yield of the pulverized product having a maximum particle size of 5 mm or less can be improved. 50 to 95%. In addition, the load on the pulverizer in the pulverization step can be reduced.
最大粒子径を５０ｍｍ以下にした木質原料を粉砕機にて粉砕する際に、チューブミル内に木質原料を乾燥させるためのガスを通気することが好ましい。木質原料の水分量が多いと、木質原料の供給処理等のハンドリング性が悪化するおそれがあり、また、チューブミル内で粉砕媒体やライナーに粉砕物が付着してしまい、効率的に木質原料を粉砕することができなくなるおそれがある。具体的には、木質原料の含水率は、４０質量％以下であることが好ましく、特に２０質量％以下であることが好ましい。なお、木質原料の含水率が著しく高い場合には、粉砕工程に付する前に乾燥機等を使用して木質原料の含水率を調整してもよい。 When a wood material having a maximum particle size of 50 mm or less is pulverized by a pulverizer, it is preferable to pass a gas for drying the wood material into the tube mill. If the moisture content of the wood raw material is large, the handling properties such as the supply processing of the wood raw material may be deteriorated, and the crushed material adheres to the grinding media and liner in the tube mill, so that the wood raw material can be efficiently used. There is a risk that it cannot be crushed. Specifically, the moisture content of the wood raw material is preferably 40% by mass or less, and particularly preferably 20% by mass or less. In addition, when the moisture content of a wooden raw material is remarkably high, you may adjust the moisture content of a wooden raw material using a dryer etc. before attaching | subjecting to a grinding | pulverization process.
粉砕工程においてチューブミル内に通気するガスとしては、木質原料を安全に乾燥することのできるものであれば特に限定されるものではなく、例えば、外気、排ガス等を使用することができる。 The gas that flows into the tube mill in the pulverization step is not particularly limited as long as it can safely dry the woody material, and for example, outside air, exhaust gas, and the like can be used.
粉砕工程においてチューブミル内に通気するガスの温度は、１０〜２５０℃であることが好ましく、特に１００〜２００℃であることが好ましい。ガスの温度が１０℃未満であると、チューブミル内において木質原料又はその粉砕物を十分に乾燥することができないおそれがあり、２５０℃を超えると、チューブミル内において木質原料又はその粉砕物が燃焼してしまうおそれがある。 The temperature of the gas vented into the tube mill in the pulverization step is preferably 10 to 250 ° C, and particularly preferably 100 to 200 ° C. If the gas temperature is less than 10 ° C., the wood raw material or pulverized product thereof may not be sufficiently dried in the tube mill. If the gas temperature exceeds 250 ° C., the wood raw material or pulverized product thereof will be contained in the tube mill. There is a risk of burning.
チューブミル内に通気するガスの通気量は、チューブミルの大きさやチューブミルへの木質原料の投入量に応じて適宜変更することができるが、一般に、ミル内の通気速度で０．１〜５．０ｍ／ｓであることが好ましく、特に０．５〜２．０ｍ／ｓであることが好ましく、さらには１．０〜２．０ｍ／ｓであることが好ましい。ミル内の通気速度が０．１ｍ／ｓ未満であると、木質原料を効果的に乾燥することができないおそれがあり、５．０ｍ／ｓを超えると、チューブミル内にて木質原料又はその粉砕物が飛散したり、木質原料又はその粉砕物のチューブミル内での移送速度が遅くなったりするおそれがある。 The amount of gas that flows into the tube mill can be appropriately changed according to the size of the tube mill and the amount of wood raw material charged into the tube mill. It is preferably 0.0 m / s, particularly preferably 0.5 to 2.0 m / s, and further preferably 1.0 to 2.0 m / s. If the ventilation rate in the mill is less than 0.1 m / s, the wood material may not be effectively dried. If it exceeds 5.0 m / s, the wood material or its pulverization in the tube mill. There is a risk that the material will scatter or the transfer speed of the wood raw material or the pulverized material in the tube mill may be slow.
粉砕工程における粉砕時間は、チューブミルへの木質原料の投入量、チューブミルの大きさ、チューブミルの粉砕性能等に応じて適宜変更することができるが、一般に５〜６０分であることが好ましく、特に１０〜３０分であることが好ましい。粉砕時間が５分未満であると、最大粒子径５ｍｍ以下の粉砕物の収率が低下し、効率的に木質原料を粉砕することができないおそれがあり、６０分を超えると、チューブミルの粉砕動力が高くなるおそれがある。 The pulverization time in the pulverization step can be appropriately changed according to the amount of the woody raw material charged into the tube mill, the size of the tube mill, the pulverization performance of the tube mill, etc., but is generally preferably 5 to 60 minutes. In particular, it is preferably 10 to 30 minutes. If the pulverization time is less than 5 minutes, the yield of the pulverized product having a maximum particle diameter of 5 mm or less may be reduced, and the wood raw material may not be efficiently pulverized. Power may be high.
次に、粉砕工程により木質原料が粉砕されて得られた粉砕物を分級し、最大粒子径５ｍｍ以下の粉砕物と最大粒子径５ｍｍを超える粉砕物とに分離する。粉砕物の分級は、例えば、網、打ち抜き板、間隙等を利用した振動篩、ドラム型スクリーン、流体分級理論を利用したサイクロン等の遠心分離機、強制風力式の分級機等を使用して行えばよい。 Next, the pulverized product obtained by pulverizing the wood raw material in the pulverization step is classified and separated into a pulverized product having a maximum particle size of 5 mm or less and a pulverized product having a maximum particle size of 5 mm or more. The pulverized material is classified using, for example, a screen, a punched plate, a vibrating screen using a gap, a drum-type screen, a centrifugal separator such as a cyclone using a fluid classification theory, or a forced wind type classifier. Just do it.
そして、分級工程により分離された最大粒子径５ｍｍ以下の粉砕物を回収する。このようにすることで、例えば、セメント製造装置におけるロータリーキルンの窯前部に投入し得る窯前燃料として使用可能な木質燃料を製造することができる。 And the pulverized material with a maximum particle diameter of 5 mm or less separated by the classification step is collected. By doing in this way, the woody fuel which can be used as a kiln fuel which can be thrown into the kiln front part of the rotary kiln in a cement manufacturing apparatus can be manufactured, for example.
最大粒子径５ｍｍを超える粉砕物は、再度粉砕工程に戻し、チューブミル内にて粉砕することで最大粒子径５ｍｍ以下の粉砕物としてもよい。このようにすることで、木質原料から木質燃料を効率的に製造することができる。なお、最大粒子径５ｍｍを超える粉砕物は、例えば、セメント製造装置におけるロータリーキルンの窯尻部に燃料として投入したり、ボイラー等の燃料として使用したりしてもよい。 The pulverized product exceeding the maximum particle size of 5 mm may be returned to the pulverization step again and pulverized in a tube mill to obtain a pulverized product having a maximum particle size of 5 mm or less. By doing in this way, a wooden fuel can be efficiently manufactured from a wooden raw material. In addition, the pulverized material exceeding the maximum particle diameter of 5 mm may be used as fuel in a kiln bottom of a rotary kiln in a cement manufacturing apparatus, or may be used as fuel for a boiler or the like.
このようにして得られた木質燃料は、セメント焼成等のような温度コントロールが必要とされる焼成用燃料として使用することができ、特にセメント製造装置におけるロータリーキルンの窯前部に投入される窯前燃料の一部として使用することができる。 The woody fuel obtained in this way can be used as a fuel for firing that requires temperature control such as cement firing, and in particular, before the kiln that is put into the kiln front of a rotary kiln in a cement manufacturing apparatus. Can be used as part of the fuel.
