Description

本発明は、籾殻の燃焼装置に関する。   The present invention relates to a rice husk combustion apparatus.

バイオマスの燃料として、流木や廃材、剪定や製材所からの切りくずをチップにしたもの、そして前記材料を粉砕し、圧縮加工して木質ペレットにして燃料としたものや、農産物の収穫後の残渣を乾燥して燃料としたものが一般である。特に稲の収穫後の乾燥作業を経て、籾摺り作業で発生する「籾殻」においては、乾燥場所に籾を集積させる過程で発生するものであるので、新たに収集する必要がなく、また籾を乾燥するための燃焼燃料として利用できることから、籾殻の発生場所が燃料として使用する場所であって、運搬コストを必要としない、環境に特にやさしいバイオマス燃料であるといえる。   Biomass fuel is made from chips from driftwood, waste wood, pruned or sawmill chips, and the material is crushed and compressed into wood pellets to produce fuel, and residues after harvesting agricultural products In general, the fuel is dried to make fuel. In particular, “rice husk” generated by rice hulling after the rice harvesting operation is generated in the process of accumulating rice straw in the drying area. Therefore, it can be said that the place where rice husks are used as fuel is a biomass fuel that is environmentally friendly and does not require transportation costs.

従来、籾殻や木質ペレット、廃材ペレットまたはおが粉等のバイオマスを燃料とする燃焼の方法や装置について様々な提案がされている。   Conventionally, various proposals have been made on combustion methods and apparatuses using biomass such as rice husk, wood pellets, waste pellets or sawdust as fuel.

特許文献1には、燃焼台の上方に外筒と内筒からなる燃焼部を備えて、内筒には燃焼燃料となるペレットを流下させ、内筒と外筒の間を燃焼用空気の供給通路として、燃焼台まで導き、さらに内筒の内を攪拌部材を通して燃焼台上で攪拌部を回転させる構成が記載されている。   Japanese Patent Laid-Open No. 2004-133620 includes a combustion section including an outer cylinder and an inner cylinder above the combustion stage, and pellets that serve as combustion fuel flow down to the inner cylinder, and supply of combustion air between the inner cylinder and the outer cylinder As the passage, there is described a configuration in which the stirrer is guided to the combustion bed and the inside of the inner cylinder is rotated through the stirring member on the combustion bed.

特許文献2では、燃焼皿上に外筒と内筒を配置し、内筒を燃料供給筒、内筒と外筒の間を燃焼空気の導入口として配置し、内筒内部上方には燃料バケット内から燃料供給筒に燃料の供給量を調節するための回転体をシャッタとして構成した構造が、特許文献3ではおが粉等のバイオマス燃料をホッパ内に投入し、ホッパ上面に取り付けられたモータによって回転軸が回転し、回転軸の攪拌棒やスクリューによって、バイオマス燃料を燃焼部のロストルに供給する装置が記載されている。   In Patent Document 2, an outer cylinder and an inner cylinder are disposed on a combustion dish, the inner cylinder is disposed as a fuel supply cylinder, a space between the inner cylinder and the outer cylinder is disposed as an inlet for combustion air, and a fuel bucket is disposed above the inner cylinder. A structure in which a rotating body for adjusting the amount of fuel supplied from the inside to the fuel supply cylinder is configured as a shutter. In Patent Document 3, a biomass fuel such as sawdust is introduced into the hopper, and a motor attached to the upper surface of the hopper Describes a device that rotates the rotating shaft and supplies biomass fuel to the rooster of the combustion section by means of a stirring rod or screw on the rotating shaft.

特許文献4には、排熱利用型くん炭製造機において、容器内の中央に備えた煙突が回転するように構成し、容器内の煙突に備えられたオーガによって、燻炭材料が強制的に燃焼室に供給されて、連続燃焼が出来る構成が記載されている。   In Patent Document 4, in the exhaust heat utilization type charcoal making machine, a chimney provided in the center of the container is configured to rotate, and the auger provided in the chimney in the container forcibly supplies the charcoal material. A configuration is described in which continuous combustion is possible by supplying to the combustion chamber.

前記特許文献1及び2の構成の燃焼装置であっては、燃焼燃料がペレットを対象としているので流動性もよく、内筒内を自然に流下させてもブリッチ現状の心配も無く、また燃焼時に至っては燃料同士の間隙が多く取れるので、通気性の良好で、安定した燃焼を得ることが出来る。しかしながら、本発明の提案する籾殻を燃焼燃料とする場合においては、流動性が乏しく、堆積させるとブリッチ現象を起こし、さらに通気性も良くないので、良好な燃焼を期待できない。そして籾殻の燃焼後の灰量はあまり少なくならないので、燃焼後の灰を滞りなく除去しないと連続しての燃焼が期待できないものである。   In the combustion apparatus having the configuration of Patent Documents 1 and 2, since the combustion fuel is targeted for pellets, the fluidity is good, and there is no concern about the current state of the blitch even when the inner cylinder is allowed to flow naturally. In the end, there are many gaps between the fuels, so that the air permeability is good and stable combustion can be obtained. However, when the rice husk proposed by the present invention is used as a combustion fuel, the fluidity is poor, and if it is deposited, a blitch phenomenon occurs, and further, the air permeability is not good, so that good combustion cannot be expected. And since the amount of ash after combustion of rice husk is not so small, continuous combustion cannot be expected unless the ash after combustion is removed without delay.

特許文献3の燃焼装置においては、燃焼部に連続的そして定量的に燃焼部の上方から燃焼燃料を供給できるものの、燃焼量に応じた供給に対しては不明確で、しかも大量に発生する燃焼灰の除去に至っては良好な構成でない。   In the combustion apparatus of Patent Document 3, combustion fuel can be supplied continuously and quantitatively from above the combustion section, but the combustion according to the amount of combustion is unclear and a large amount of combustion occurs. It is not a good structure for removing ash.

そこで、籾殻を専用の燃焼燃料として使用する燃焼装置として構成し、常に連続して籾殻を薄層状に連続的に流下させると共に、籾殻層の内部から外部に向け均一に籾殻に燃焼用の通風を行なうことを可能とすること、そして燃焼の終わった籾殻をすばやく燃焼部から除去することによって、燃焼部に常に燃焼中の燃料を供給し、安定した燃焼が可能となる籾殻専用の燃焼装置を提供することを目的とする。   Therefore, it is configured as a combustion device that uses rice husk as a dedicated combustion fuel, and continuously flows down the rice husk continuously in a thin layer, and also provides uniform ventilation to the rice husk from the inside of the rice husk layer to the outside. Providing a combustor dedicated to rice husk that enables stable combustion by constantly supplying fuel during combustion by quickly removing burned rice husk from the combustion section.

また、図1の攪拌翼B18は、攪拌容器10の逆円錐形状の傾斜面に対して設けられていて、傾斜面で滞ろうとする籾殻を攪拌し、傾斜面を下降させるはたらきと、天板6の燃料供給口7から供給される籾殻を、外筒容器4の攪拌容器10内に、均等に張り込む作用のために設けられている。   Moreover, the stirring blade B18 of FIG. 1 is provided with respect to the inverted conical inclined surface of the stirring vessel 10, and functions to stir the rice husk that is stagnating on the inclined surface and lower the inclined surface, and the top plate 6. The rice husk supplied from the fuel supply port 7 is provided for the purpose of evenly sticking the rice husk into the stirring container 10 of the outer cylinder container 4.

内筒5の下方は、燃焼容器9の多孔面A11の上端と略同一の高さから開口する開口面19と、多孔面A11と接触しない範囲で多孔面B12に若干の隙間を置いて設けられた拡散翼21とを、固定桟20でつなぎ合わせた形態で構成される。この固定桟20は内筒5に開口面19を二面切り取った残りの桟や、新たに別部材を溶接又はねじ止めしたものであっても良い。   The lower side of the inner cylinder 5 is provided with an opening surface 19 that opens from substantially the same height as the upper end of the porous surface A11 of the combustion container 9, and a slight gap in the porous surface B12 within a range that does not contact the porous surface A11. The diffusion blades 21 are connected to each other by a fixed bar 20. This fixed crosspiece 20 may be the remaining crosspiece obtained by cutting the opening surface 19 into the inner cylinder 5 or another member newly welded or screwed.

図3に示すように、攪拌翼21は固定桟20の二箇所と固定された通し棒であって、燃焼容器9の側面の多孔面A11と、底面の多孔面B12と若干の距離を置いて、内筒5が回転してもそれぞれに干渉しない形状となっている。またこの攪拌翼は図5に示すように、固定桟20のそれぞれの外周面に固定される三角形状態の攪拌翼22でもよい。   As shown in FIG. 3, the stirring blade 21 is a through-rod fixed to two places of the fixed bar 20, and is slightly spaced from the porous surface A11 on the side surface of the combustion vessel 9 and the porous surface B12 on the bottom surface. The inner cylinder 5 does not interfere with each other even if it rotates. Further, as shown in FIG. 5, the stirring blade may be a triangular stirring blade 22 fixed to each outer peripheral surface of the fixed bar 20.

以上のように、内筒5と外筒容器4が構成されているが、内筒5の内部はその上端の吸引口13から吸引される外気、即ち燃焼用空気通路23として構成され、内筒5と外筒容器4の間の空間、即ち円状の外周とその内部中央の円状の空間からなる、平面視で略ドーナツ状の籾殻流下層24を形成している。   As described above, the inner cylinder 5 and the outer cylinder container 4 are configured. The inner cylinder 5 is configured as outside air sucked from the suction port 13 at the upper end thereof, that is, as a combustion air passage 23. A substantially donut-shaped rice husk lower layer 24 is formed in a plan view, which is composed of a space between the outer cylindrical container 4 and the outer cylindrical container 4, that is, a circular outer periphery and a circular space in the center of the outer periphery.

この籾殻流下層24はその作用よって、上方から攪拌容器10から内筒5又は燃焼容器9が余り加熱されていない部分までを燃料供給通路25として、燃焼容器9と内筒5が加熱され始めている部分から開口面19を若干過ぎたあたりまでを、燃焼ガス発生領域、それ以降から攪拌翼21・22の上端までを燃焼領域27、それ以降を燃焼灰除去領域として構成されている。   Due to the action of the rice husk flow lower layer 24, the combustion container 9 and the inner cylinder 5 start to be heated from above the stirring container 10 to the portion where the inner cylinder 5 or the combustion container 9 is not heated so much as the fuel supply passage 25. From the portion to the portion slightly past the opening surface 19 is configured as a combustion gas generation region, the subsequent region to the upper end of the stirring blades 21 and 22 as a combustion region 27, and the subsequent region as a combustion ash removal region.

燃焼排風部3はその全面に耐熱部材29を施した燃焼室30と排風装置32を備える煙突31からなる。排風装置32は燃焼室30内の燃焼風を機外に強制的に排除できるものであって、排気ファンの入り口又は出口に煙突31を直接接合した強制吸引でも良いが、煙突31を高くして、ドラフトによる燃焼室30の燃焼風の排気を妨げないよう、図1のような煙突内に、その排出方向に向けて高速風を供給することによって、回りの空気を排出方向に移動させる排風方式であると、排風装置32が耐熱性を必要としないので構造面やコスト面でも良好である。   The combustion exhaust section 3 includes a chimney 31 including a combustion chamber 30 having a heat-resistant member 29 on the entire surface and an exhaust apparatus 32. The exhaust device 32 can forcibly remove the combustion air in the combustion chamber 30 outside the machine, and may be forced suction with the chimney 31 directly joined to the inlet or outlet of the exhaust fan. In order not to hinder the exhaust of the combustion air in the combustion chamber 30 due to the draft, the high-speed air is supplied into the chimney as shown in FIG. 1 in the exhaust direction to move the surrounding air in the exhaust direction. When the wind system is used, the air exhaust device 32 does not require heat resistance, which is favorable in terms of structure and cost.

燃焼室30には、その上面から供給燃焼部2の外筒容器4が差し込まれていて、燃焼容器9が燃焼室30内に配置されるようになっている。なお燃焼容器9が差し込まれる部分は燃焼室30内に外気の流通が無いよう、密着して配置されている。   The outer cylinder container 4 of the supply combustion unit 2 is inserted into the combustion chamber 30 from the upper surface, and the combustion container 9 is arranged in the combustion chamber 30. The portion into which the combustion container 9 is inserted is arranged in close contact with the combustion chamber 30 so that there is no circulation of outside air.

燃焼室30内に配置された燃焼容器9から均一な距離を取って、仕切り壁33が燃焼室30の上面から備えられている。この仕切り壁33は燃焼容器9と同等の高さか、それより長い全長を持って備えられているので、燃焼容器9の側面を取り囲む配置となっており、この仕切り壁33内を一次燃焼室34として、そしてそれ以外の燃焼室内を二次燃焼室35として構成されている。   A partition wall 33 is provided from the upper surface of the combustion chamber 30 at a uniform distance from the combustion container 9 disposed in the combustion chamber 30. Since the partition wall 33 is provided with a height equal to or longer than that of the combustion container 9, the partition wall 33 is disposed so as to surround the side surface of the combustion container 9, and the primary combustion chamber 34 is disposed inside the partition wall 33. The other combustion chambers are configured as secondary combustion chambers 35.

駆動部16からスプロケット14に動力が伝達されるので、内筒5が低速で回転を開始する。それに伴って内筒5に備えられた攪拌翼A17、攪拌翼B18又は攪拌翼(21・22)が回転を行う。外筒容器4内に投入された籾殻は燃料供給通路25、即ち攪拌容器10内で内筒5の外周に設けられた攪拌翼B18によって攪拌され、籾殻が攪拌容器10の全体に略均一に堆積される。さらに攪拌翼A17によって籾殻が滞りなく攪拌容器10から燃焼容器9方向に略隙間無く均一に詰まった籾殻の状態で降下を開始する。   Since power is transmitted from the drive unit 16 to the sprocket 14, the inner cylinder 5 starts rotating at a low speed. Along with this, the stirring blade A17, the stirring blade B18 or the stirring blade (21, 22) provided in the inner cylinder 5 rotates. The rice husk put into the outer cylinder container 4 is stirred by the stirring blade B 18 provided on the outer periphery of the inner cylinder 5 in the fuel supply passage 25, that is, the stirring container 10, and the rice husk is deposited almost uniformly on the entire stirring container 10. Is done. Further, the stirring blade A17 starts to descend in a state of rice husks that are uniformly packed without any gap from the stirring vessel 10 toward the combustion vessel 9 without stagnation.

燃焼容器9内に達した籾殻は、内筒5の開口面19と燃焼容器9の多孔面A11に内筒内の燃焼用空気通路23から供給される空気によって、平面視ドーナツ形状の薄層の籾殻層の内側から外側に向けて通気されて、籾殻が燃焼する燃焼領域27を形成する。   The rice husk that has reached the inside of the combustion container 9 is formed into a donut-shaped thin layer in plan view by the air supplied from the combustion air passage 23 in the inner cylinder to the opening surface 19 of the inner cylinder 5 and the porous surface A11 of the combustion container 9. Aeration is performed from the inside to the outside of the rice husk layer to form a combustion region 27 in which the rice husk burns.

内筒の開口面19と多孔面A11に達しない燃焼領域27の上方の部分は、燃焼領域27の燃焼によって、内筒5と燃焼容器9は加熱されるので、籾殻が過熱され燃焼用のガスが発生する部分、即ち燃焼ガス発生領域26を形成する。   Since the inner cylinder 5 and the combustion vessel 9 are heated by the combustion in the combustion region 27 in the portion above the opening surface 19 of the inner tube and the porous surface A11, the rice husk is overheated and the combustion gas Is formed, that is, a combustion gas generation region 26 is formed.

この燃焼ガス発生領域26で籾殻からのガスが発生しているので、燃焼領域において効率よく籾殻の燃焼を行うことが出来る。   Since the gas from the rice husk is generated in the combustion gas generation region 26, the rice husk can be efficiently burned in the combustion region.

燃焼領域27における籾殻の供給は図4又は図6のように、固定桟20の回転による効果や、もともと内筒5の直下であるので籾殻が多孔面B12の中央にはあまり供給されないので、燃焼用空気通路23からの燃焼風通気が多孔面B12にも達し、多孔面B12の中央付近でも良好な燃焼を得ることが可能である。   As shown in FIG. 4 or FIG. 6, the supply of rice husks in the combustion region 27 is the effect of the rotation of the fixed bar 20, and since the rice husks are originally directly below the inner cylinder 5, the rice husks are not supplied to the center of the porous surface B12. The ventilation of the combustion air from the air passage 23 reaches the porous surface B12, and good combustion can be obtained even near the center of the porous surface B12.

燃焼領域27で燃焼した籾殻は炭化状態又は、灰状態になってその形状を若干小さく、そして流動しづらくなって多孔面B12上に堆積しようとするが、拡散翼21・22の回転によって攪拌され続けるので、多孔面B12や多孔面A11の孔から機外に排出される燃焼灰除去領域28が形成されている。   The rice husks burned in the combustion zone 27 are carbonized or ashed and slightly reduced in shape, and are difficult to flow and try to deposit on the porous surface B12, but are stirred by the rotation of the diffusion blades 21 and 22. Since it continues, the combustion ash removal area | region 28 discharged | emitted out of the machine from the hole of the porous surface B12 or the porous surface A11 is formed.

以上のように内筒5と外筒容器4との間の籾殻流下層24では、燃焼灰除去領域28で燃焼が略終了した燻炭状態や、灰になった状態の籾殻を、内筒5の下端に固定した攪拌翼21・22の回転によって、強制的に燃焼容器9内から排出することが出来るので、燃料供給通路25から燃焼ガス発生領域26、燃焼領域27そして燃焼灰除去領域28とスムーズに籾殻の層を隙間無く均等に降下させることが出来、燃焼領域27においては、薄層の籾殻層に燃焼に必要な燃焼空気を平面視ドーナツ状の内側空間から外側の略全周に十分通気させることで、良好な燃焼を行うことが出来る。   As described above, in the rice husk flow lower layer 24 between the inner cylinder 5 and the outer cylinder container 4, the charcoal state in which the combustion is almost finished in the combustion ash removal region 28 or the rice husk in the ash state is used as the inner cylinder 5. Can be forcibly discharged from the combustion vessel 9 by the rotation of the stirring blades 21 and 22 fixed to the lower end of the combustion chamber, so that the combustion gas generation region 26, the combustion region 27, and the combustion ash removal region 28 can be removed from the fuel supply passage 25. The rice husk layer can be smoothly lowered evenly without any gaps, and in the combustion region 27, the combustion air required for combustion is sufficiently applied to the thin rice husk layer from the donut-shaped inner space in plan view to the entire outer periphery. Good ventilation can be performed by aeration.

籾殻の燃焼後の容積は木質バイオマス燃料と比較しても、その容積はあまり小さくはならないので、燃焼領域から燃焼が略終了した籾殻をいち早く除去することによって、連続的そして安定的な籾殻の燃焼を可能とすることができる。   Since the volume of rice husk after combustion is not much smaller than that of woody biomass fuel, continuous and stable combustion of rice husk can be achieved by quickly removing the rice husk that has been almost burned out from the combustion area. Can be made possible.

燃焼排風部3即ち燃焼室30内に燃焼ガス発生領域26と燃焼領域27又は燃焼灰除去領域28を備え、そしてこれらの領域を仕切り壁33で囲っているので、煙突31に備えられた排風装置32の燃焼室30に対する吸引作用によって、自ずと炎と燃焼風は下方向に向けて放出される。そして内筒5はその内部が燃焼用空気通路23をなし、常に外気を吸引しているので、燃料供給通路25までの間、即ち攪拌容器10と内筒5とその間に挟まれた籾殻への熱の伝熱がない。   A combustion gas generation region 26 and a combustion region 27 or a combustion ash removal region 28 are provided in the combustion exhaust air portion 3, that is, the combustion chamber 30, and these regions are surrounded by the partition wall 33, so that the exhaust provided in the chimney 31 is provided. Due to the suction action of the wind device 32 on the combustion chamber 30, the flame and the combustion wind are naturally discharged downward. Since the inside of the inner cylinder 5 forms a combustion air passage 23 and always sucks outside air, the fuel is supplied to the fuel supply passage 25, that is, the stirring vessel 10 and the inner cylinder 5 and the rice husk sandwiched between them. There is no heat transfer.

外筒容器4の攪拌容器10内においては、天板6の籾殻供給口7から若干外気が流入できるように構成されているが、攪拌容器10内には籾殻が充填されているので、燃焼領域からの伝熱が攪拌容器10とその付近の空間を上昇しようしても、籾殻によって空気の流通が遮断されているほか、攪拌容器10自体の伝熱は、常に降下する籾殻によって冷やされるので、攪拌容器10と籾殻供給通路25の温度上昇を懸念する必要がない。また、籾殻が供給されず、籾殻流下層24に籾殻がなくなっても、天板6から外気若干吸引されるのでその外気の流入により、攪拌容器10自体の温度上昇と、攪拌容器10内に燃焼ガスの滞留が発生することがなく、安全性にも優れるものである。   In the stirring container 10 of the outer cylinder container 4, it is configured so that some outside air can flow in from the rice husk supply port 7 of the top plate 6. However, since the stirring container 10 is filled with rice husk, the combustion region Even if the heat transfer from the vessel tries to rise in the stirring vessel 10 and the space in the vicinity thereof, the air flow is blocked by the rice husk, and the heat transfer of the stirring vessel 10 itself is always cooled by the falling rice husk. There is no need to worry about the temperature rise of the stirring vessel 10 and the rice husk supply passage 25. Further, even if the rice husk is not supplied and the rice husk is not present in the rice husk lower layer 24, the outside air is slightly sucked from the top plate 6, so that the inflow of the outside air causes the temperature of the stirring vessel 10 itself to rise and combustion into the stirring vessel 10. There is no gas stagnation and safety is excellent.

仕切り壁33で囲まれた部分、即ち一次燃焼室34において、籾殻から発生する燃焼ガスによる燃焼が行われるが、籾殻が炭化状態(燻炭)即ち燃焼ガスの発生が終了した段階で、燃焼灰除去領域28から排出され、燃焼室30の下端に堆積して燻炭堆積層39・40を形成する。そして燻炭堆積層39・40の状態においても、炭化状態での燃焼が二次燃焼室35において行われていく。   In the portion surrounded by the partition wall 33, that is, in the primary combustion chamber 34, combustion is performed by the combustion gas generated from the rice husk. When the rice husk is carbonized (coal charcoal), that is, when the generation of the combustion gas is finished, the combustion ash It is discharged from the removal region 28 and is deposited on the lower end of the combustion chamber 30 to form the charcoal deposit layers 39 and 40. Even in the state of the charcoal deposit layers 39 and 40, combustion in the carbonized state is performed in the secondary combustion chamber 35.

燃焼室30の下端に堆積する燻炭堆積層39・40のその底面から炭化状態から灰へと燃焼を終了していくので、図示してはいないが燻炭の堆積層下端から灰を燃焼室30外に排出する装置を備えることによって、二次燃焼室35の連続的な籾殻燃焼を行うことが出来る。   Combustion is completed from the bottom surface of the charcoal deposits 39 and 40 deposited at the lower end of the combustion chamber 30 from the carbonized state to the ash. By providing a device for discharging outside 30, continuous rice hull combustion in the secondary combustion chamber 35 can be performed.

籾殻燃焼装置を稼動させる作業者は、籾殻供給装置8又は手動で外筒容器4の天板6から燃焼燃料となる籾殻を、攪拌容器10内の燃料供給通路25の略全周に渡って籾殻が充填されるまで籾殻の投入をおこない、攪拌容器10の上端方向に多くの間隙がある状態で、籾殻の投入を停止する。   An operator who operates the rice husk combustion apparatus manually supplies the rice husk as combustion fuel from the top plate 6 of the outer cylinder container 4 or the rice husk manually over the entire circumference of the fuel supply passage 25 in the stirring container 10. The rice husks are charged until the husks are filled, and the charging of the rice husks is stopped while there are many gaps in the upper end direction of the stirring vessel 10.

その後、駆動部16を稼動させずに、即ち内筒5の回転を行わずに、燃焼用空気通路23から火種を投入するか、燃焼容器9の多孔面に外部から炎を当てて籾殻に着火し、種火を発生させる。その後に排風装置32を若干作動させて、燃焼領域の籾殻に若干の燃焼用空気通路23からの通風をおこない、火種の炎を徐々に広げていく。   Thereafter, without operating the drive unit 16, that is, without rotating the inner cylinder 5, a fire type is introduced from the combustion air passage 23, or a flame is externally applied to the porous surface of the combustion container 9 to ignite the rice husk. And generate a fire. After that, the air exhaust device 32 is operated slightly to ventilate the rice husk in the combustion region from the combustion air passage 23 to gradually widen the flame of the fire type.

徐々に籾殻の燃焼が燃焼領域全体に広がっていくと共に、排風装置32を通常の稼動状態に設定し煙突31から燃焼室30の燃焼風を機外に排出する。   The combustion of the rice husk gradually spreads over the entire combustion region, and the air exhaust device 32 is set to a normal operation state, and the combustion air in the combustion chamber 30 is discharged from the chimney 31 to the outside of the machine.

着火時及びその直後は内筒5を回転させていないので、外筒容器4の燃焼容器9の下方の多孔面B12や多孔面A11の下方に、燃焼ガスが放出しきった燻炭や、すでに灰になった籾殻が堆積しているので、燃焼ガスの放出を行える新たな籾殻が燃焼領域27や、燃焼ガス発生領域26まで降下できないため、燃焼領域27の燃焼量が減少を始めるので、駆動部16の稼動を徐々に開始し、内筒5をゆっくりと回転させていく。   Since the inner cylinder 5 is not rotated at the time of ignition and immediately after that, the charcoal from which the combustion gas has been released or the ash has already been released below the porous surface B12 and the porous surface A11 of the combustion container 9 of the outer cylinder container 4. Since the new rice husks that have become accumulated cannot be lowered to the combustion region 27 or the combustion gas generation region 26, the amount of combustion in the combustion region 27 starts to decrease. The operation | movement of 16 is started gradually and the inner cylinder 5 is rotated slowly.

内筒5のこのときの回転を、急速に通常の回転にしてしまうと、一次燃焼室34自体の温度上昇があまりなされていないので、火種の部分をも多孔面から排出し、消火してしまうこととなる。よって、内筒5はゆっくりと回転させて、多孔面B12・A11から燃焼室底部に排出する燻炭若しくは灰の量を徐々に多くして、燃焼ガス発生領域26や燃焼領域27に送られる籾殻の量を増やし、燃焼量を高め、燃焼部そして一次燃焼室34の温度を高温にしていくことにより、連続して籾殻を燃焼させることが出来る。   If the rotation of the inner cylinder 5 at this time is rapidly changed to a normal rotation, the temperature of the primary combustion chamber 34 itself is not increased so much, so that the part of the fire type is also discharged from the porous surface and extinguished. It will be. Therefore, the inner cylinder 5 is slowly rotated to gradually increase the amount of charcoal or ash discharged from the porous surfaces B12 and A11 to the bottom of the combustion chamber, and sent to the combustion gas generation region 26 and the combustion region 27. By increasing the amount of gas, increasing the amount of combustion, and increasing the temperature of the combustion section and the primary combustion chamber 34, the rice husk can be burned continuously.

連続して燃焼を続けることによって、燃焼灰排出領域28から排出される燻炭や灰によって、一次燃焼室34の下方の二次燃焼室35の部分に燻炭状態の籾殻やその灰が堆積する燻炭堆積層39・40を形成するが、まだ燻炭状態であるので炭化部分の燃焼を継続し、二次燃焼室35自体も高温となって燃焼室30全体を高温にすることが出来る。   By continuously burning, the charcoal and the ash accumulate in the portion of the secondary combustion chamber 35 below the primary combustion chamber 34 due to the charcoal and ash discharged from the combustion ash discharge region 28. Although the charcoal deposit layers 39 and 40 are formed, since the charcoal is still in the charcoal state, the combustion of the carbonized portion is continued, and the secondary combustion chamber 35 itself becomes high in temperature so that the entire combustion chamber 30 can be heated.

燃焼室30自体が高温で、煙突31が長く設けられていると、良好なドラフトを得ることが出来るので、排気装置32を停止しても煙突31から燃焼室30内の燃焼風を強制的に、そして燃焼用空気通路23から自然に外気を吸入することが出来るものである。   If the combustion chamber 30 itself is hot and the chimney 31 is long, a good draft can be obtained. Therefore, even if the exhaust device 32 is stopped, the combustion air in the combustion chamber 30 is forced from the chimney 31. In addition, the outside air can be naturally sucked from the combustion air passage 23.

上記のように燃焼室30全体がある程度の高温状態にある場合、内筒5の回転を遅くすることによって籾殻流下層を降下する籾殻の量を減らし、籾殻から発生するガスの量を減少させることで、燃焼量の調節を行うことが出来るものである。   When the combustion chamber 30 as a whole is in a certain high temperature state as described above, the amount of rice husk descending the rice husk flow layer is reduced by slowing the rotation of the inner cylinder 5, and the amount of gas generated from the rice husk is reduced. Thus, the amount of combustion can be adjusted.

籾殻燃焼装置の停止時にあっては、内筒5の回転を止めることによって燃焼灰除去領域28から燻炭又は灰が燃焼容器9外に排出されないので、燃焼領域27・燃焼ガス発生領域26に新たな籾殻が供給されず、自然と炎は減少し、自ずと消化されていく。但し燃焼室30内に堆積した燻炭状態の籾殻の燃焼は継続しているので、炎の鎮火後もある程度排風装置32の稼動を要して、燃焼室30全体の温度低下を促す必要がある。   When the rice husk combustion device is stopped, the rotation of the inner cylinder 5 is stopped, so that no charcoal or ash is discharged from the combustion ash removal region 28 to the outside of the combustion container 9. Natural rice husks are not supplied, and the natural and flames are reduced and naturally digested. However, since the combustion of the charcoal rice husk accumulated in the combustion chamber 30 continues, it is necessary to operate the exhaust device 32 to some extent even after the flame is extinguished to promote a temperature decrease of the entire combustion chamber 30. is there.

また、籾殻燃焼装置の停止方法としてのもう一例は、攪拌容器10内への籾殻の投入を停止し、籾殻流下層24の籾殻をすべて燃焼後排出してしまうことで、消化が可能となる。しかしこの場合、籾殻流下層24の上方の燃料供給通路25には籾殻は介在しないので、燃焼ガス発生領域28で発生した燃焼ガスの逆流現象が生じ、攪拌容器10内で、爆発が発生する恐れが生じる。しかしながら、燃料供給口7や天板6からは外気の流通を妨げていないので、攪拌容器10内に籾殻が介在していない空間を排風装置32の作用によって、燃料供給口7や天板6から外気が若干流入され、攪拌容器10内に燃焼ガスが滞留することなく、安全性にも優れるものである。   Another example of a method for stopping the rice husk combustion apparatus is to stop the introduction of the rice husk into the stirring vessel 10 and discharge all the rice husks in the rice husk lower layer 24 after combustion, thereby enabling digestion. However, in this case, since the rice husk is not interposed in the fuel supply passage 25 above the rice husk lower layer 24, a reverse flow phenomenon of the combustion gas generated in the combustion gas generation region 28 occurs, and an explosion may occur in the stirring vessel 10. Occurs. However, since the flow of outside air is not hindered from the fuel supply port 7 and the top plate 6, the fuel supply port 7 and the top plate 6 are moved by the action of the air exhaust device 32 in the space where the chaff is not present in the stirring vessel 10. Therefore, the outside air is slightly flowed in, and the combustion gas does not stay in the stirring vessel 10, and the safety is excellent.

図7は本発明の第二の実施の形態を示す籾殻燃焼装置36である。図1に示す第一の実施の形態の籾殻燃焼装置1に示す実施例1の構成において、内筒5の開口面19を、多孔部38として内筒37に設けた構成を示す形態のものである。   FIG. 7 shows a rice husk combustion apparatus 36 showing a second embodiment of the present invention. In the configuration of Example 1 shown in the rice husk combustion apparatus 1 of the first embodiment shown in FIG. 1, the configuration in which the opening surface 19 of the inner cylinder 5 is provided in the inner cylinder 37 as the porous portion 38 is shown. is there.

内筒37の多孔部38は実施例1の開口面19と同様に、燃焼容器9の多孔面A11の上端と略同一の高さから内筒の略下端にまで孔が設けられていて、内筒37の下端には燃焼容器9の底面の多孔面B12と若干の距離を置いて、そして側面の多孔面A11と接触しないように設けられた通し棒の拡散翼21(図9)が設けられている。この拡散翼は図10に示すような内筒37の下端の外周面に固定されている三角形状の攪拌翼22であっても良い。   The porous portion 38 of the inner cylinder 37 is provided with a hole from substantially the same height as the upper end of the porous surface A11 of the combustion vessel 9 to the substantially lower end of the inner cylinder, like the opening surface 19 of the first embodiment. At the lower end of the cylinder 37, there is provided a through-rod diffusion blade 21 (FIG. 9) provided at a slight distance from the porous surface B12 on the bottom surface of the combustion vessel 9 and so as not to contact the porous surface A11 on the side surface. ing. This diffusion blade may be a triangular stirring blade 22 fixed to the outer peripheral surface of the lower end of the inner cylinder 37 as shown in FIG.

このように内筒37を拡散翼21・22に接合する位置まで備えることによって、燃焼ガス発生領域26や燃焼領域27を通過する籾殻は、堆積した層状態のまま徐々に落下し、内筒5の燃装用空気通路23からの通風を多孔部38のそれぞれの孔を通り、薄層の籾殻層を通り抜け、燃焼容器9の多孔面A11又は多孔面B12から炎や燃焼風となって通過する。そして内筒5の直下の多孔面B12の中央は、特に籾殻や燃焼後の燻炭の供給が少なくなるので、燃焼用空気通路23の外気を燃焼室30内に通気しやすくなり、拡散翼21・22の回転によって燃焼灰除去領域28から排出される燻炭が堆積する燻炭堆積層
39に外気を供給できるため、燻炭堆積層39の燻炭状態での燃焼が活発に行われ、いち早く灰へと移行できるようになる。
By providing the inner cylinder 37 up to the position where the inner wing 37 is joined to the diffusion blades 21 and 22 as described above, the rice husk passing through the combustion gas generation region 26 and the combustion region 27 gradually falls in the accumulated layer state, and the inner cylinder 5 Ventilation from the combustion air passage 23 passes through each hole of the porous portion 38, passes through the thin rice husk layer, and passes through the porous surface A11 or the porous surface B12 of the combustion container 9 as a flame or combustion air. In the center of the porous surface B12 immediately below the inner cylinder 5, the supply of rice husk and fired charcoal particularly decreases, so that the outside air of the combustion air passage 23 can be easily vented into the combustion chamber 30, and the diffusion blade 21 Since outside air can be supplied to the charcoal deposit layer 39 in which the charcoal discharged from the combustion ash removal region 28 is accumulated by the rotation of 22, combustion in the charcoal state of the charcoal deposit layer 39 is actively performed, Can move to ash.

実施例1における第一の実施の形態での燃焼室30に堆積する燻炭堆積層40であっては、燻炭堆積層40付近に外気即ち酸素が供給されないので、燃焼室30内での燻炭から灰への燃焼反応が行われにくく、燻炭堆積層40の堆積量が増加して、その一部を機外に排出する必要性が生じた場合にあっては、燻炭状態での燃焼が継続して高温になるため、十分な取り扱いを行う必要が発生する。   In the soot deposit layer 40 deposited in the combustion chamber 30 in the first embodiment in Example 1, outside air, that is, oxygen is not supplied to the vicinity of the soot deposit layer 40, soot in the combustion chamber 30. In the case where the combustion reaction from charcoal to ash is difficult to occur, and the amount of deposit of the charcoal deposit layer 40 increases, and it becomes necessary to discharge a part of it to the outside of the aircraft, Since the combustion continues to become high temperature, it is necessary to handle it sufficiently.

これに対し、実施例2の本発明の第二の実施の形態のように、燻炭堆積層40付近にまで、十分に酸素を含んだ空気を送り込むことによって、燻炭状態から灰への燃焼を促進させることが出来るので、籾殻の持つ燃焼エネルギーすべてを有効に利用できると共に、燻炭堆積層39から機外にそれを排出しても、灰状態である場合や、ある程度の燻炭状態が混ざっていても、自然に燃焼が終了するので、厳重な取り扱いを強いられることがない。   On the other hand, as in the second embodiment of Example 2 of the present invention, the combustion from the charcoal state to the ash is carried out by sending air sufficiently containing oxygen to the vicinity of the charcoal deposit layer 40. The combustion energy of the rice husk can be used effectively, and even if it is discharged from the coal accumulation layer 39 to the outside of the machine, it is in the ash state, or a certain amount of the charcoal state. Even if they are mixed, the combustion ends naturally, so strict handling is not required.

実施例2の本発明の第二の実施の形態においては、その取り扱い及び点火、消化の方法は実施例1と同様であるので記載は省略する。   In the second embodiment of the present invention in Example 2, the handling, ignition, and digestion methods are the same as in Example 1, and therefore the description thereof is omitted.
