Description

本発明は、有機質又は無機質の含液被処理を乾燥、前者の場合は、さらには炭化(乾留)も同時的に行うことができる新規な減圧乾燥/炭化装置に関し、特に、含液有機廃棄物を乾燥/炭化処理をするに好適なものである。   The present invention relates to a novel reduced-pressure drying / carbonization apparatus that can dry an organic or inorganic liquid-containing treatment, and in the case of the former, carbonization (dry distillation) at the same time. Is suitable for drying / carbonizing.
ここで、含液有機廃棄物としては、各種汚泥、人糞、家畜糞尿、オカラ、生ごみ、食品残渣、木質系/プラスチック系/ゴム系廃棄物等の有機物系廃棄物のみならず、包帯、ガーゼ、オムツ等の医療廃棄物その他の含液有機廃棄物を含むものである。   Here, liquid-containing organic wastes include various sludges, human feces, livestock excreta, okara, food waste, food residues, wood-based / plastic-based / rubber-based organic wastes, bandages, This includes medical waste such as gauze and diapers and other liquid organic waste.
ここでは、被処理物として、含液有機廃棄物を例に採り説明するが、含液有機廃棄物に限定されるものではない。   Here, a liquid-containing organic waste is described as an example of the object to be treated, but is not limited to a liquid-containing organic waste.
従来の乾燥炭化装置は、乾燥炉と炭化炉が分離されていたり、ガス冷却塔やバグフィルターを必要としたりして、装置が複雑でトラブルも多く処理品もよいものが得られなかった。炭化機には、一部原料を燃やして蒸し焼きにする方法もあるが、これは灰が多く出ることになり、良質な炭(乾留物)を得難い。   The conventional drying carbonization apparatus has been separated from the drying furnace and the carbonization furnace, or requires a gas cooling tower or a bag filter, so that the apparatus is complicated, troublesome, and processed products cannot be obtained. Carbonizers have a method of burning some raw materials and steaming them, but this produces a lot of ash, making it difficult to obtain good quality charcoal (distilled product).
各種汚泥、人糞、家畜糞尿、オカラ、生ごみ、食品残渣等の有機廃棄物は、乾燥処理して肥料等の再利用できるが、他の木質系/プラスチック系/ゴム系廃棄物や上記医療廃棄物は、そのような形での再利用はできない。   Organic waste such as various types of sludge, human excrement, livestock excrement, okara, food waste, food residues, etc. can be dried and reused as fertilizer, etc., but other woody / plastic / rubber wastes and the above medical Waste cannot be reused in that way.
そこで、それらを一緒に炭化することが考えられる。このため、有機物の炭化装置が各種市場に出回っている、すなわち、上市されている。   Therefore, it is conceivable to carbonize them together. For this reason, organic carbonization devices are on the market, that is, are marketed.
しかし、これらの炭化装置は、含水廃棄物においては、脱水・乾燥処理手段(乾燥装置)と乾留手段(炭化装置)は別手段としたもので、乾燥装置と乾留(炭化)装置の双方が必要であった。また、通常、ガス冷却塔やバグフィルターを必要とし、装置が複雑で、処理品(炭化物又は乾留物)として品質の良いものを得難かった。   However, these carbonization equipment is a separate means for dewatering and drying treatment means (drying equipment) and dry distillation means (carbonization equipment) in hydrous waste, and both drying equipment and dry distillation (carbonization) equipment are required. Met. Further, usually, a gas cooling tower and a bag filter are required, the apparatus is complicated, and it is difficult to obtain a processed product (carbide or carbonized product) having a good quality.
なお、炭化装置では、被処理物の一部を燃焼させて、蒸し焼きにする方法であるが、これは、灰が多く出て、やはり、品質の良い炭化物を得難かった。   In the carbonization apparatus, a part of the object to be treated is burned and steamed, but this is because it is difficult to obtain a high quality carbide because of the large amount of ash.
これらの技術は、本発明者が、現場や他社製品を見聞したものを述べたものであり、特定に先行技術文献に記載されたものではない。   These techniques describe what the inventors have observed on-site and other companies' products, and are not specifically described in prior art documents.
なお、本発明の発明性に影響を与えるものではないが、本発明に使用する減圧乾燥/炭化装置に関連する先行技術文献として、本発明者自身が先に提案した特許文献1等が存在する。
特開2000−320967号公報
In addition, although it does not affect the inventiveness of the present invention, there is Patent Document 1 or the like previously proposed by the inventor as a prior art document related to the vacuum drying / carbonization apparatus used in the present invention. .
JP 2000-320967 A
本発明は、上記にかんがみて、含液(有機)廃棄物を乾燥、さらには、適宜炭化するに際して、乾燥/炭化処理を一つの装置で、効率良く、しかも、高品質の炭化物を得ることができる減圧乾燥/炭化装置を提供することを目的とする。   In view of the above, in the present invention, when a liquid-containing (organic) waste is dried, and further appropriately carbonized, the drying / carbonization treatment can be efficiently performed with a single apparatus to obtain a high-quality carbide. An object of the present invention is to provide a vacuum drying / carbonization apparatus that can be used.
本発明の減圧乾燥/炭化装置は、上記課題を下記構成により解決するものである。

なお、本発明において、上記混合手段、減圧・噴射手段、熱気熱源の態様は下記の如くとする。   In the present invention, the mixing means, the pressure reducing / injecting means, and the hot air heat source are as follows.
混合手段は、連続運転が容易な攪拌機(固定型)とする。炭化室を回転させる容器回転型としてもよい(ロータリバルブ等の接続手段が必要である。)。   The mixing means is a stirrer (fixed type) that can be continuously operated easily. It is good also as a container rotation type which rotates a carbonization chamber (connecting means, such as a rotary valve, is required).
減圧・噴射手段は、構造が簡単でメインテナンスも容易な、エア(空気)を第1流体(駆動流体)とするエジェクタ(以下「エアエジェクタ」という。:噴射ポンプ)とする。気体輸送機(圧縮機:ターボ型、容積型を含む。)と噴射ノズル(スプレーノズル)とを組み合わせて使用可能である。   The pressure reducing / injecting means is an ejector having air (air) as a first fluid (driving fluid) that has a simple structure and is easy to maintain (hereinafter referred to as “air ejector”: injection pump). A gas transporter (compressor: including a turbo type and a positive displacement type) and an injection nozzle (spray nozzle) can be used in combination.
熱気熱源は、通常、バーナ又は電熱ヒータ(抵抗加熱器)とする。設備が大型とする場合は、熱風発生炉を石炭や木質燃料等の燃焼炉(釜)としてもよい。   The hot air heat source is usually a burner or an electric heater (resistance heater). When the facility is large, the hot air generating furnace may be a combustion furnace (cooker) such as coal or wood fuel.
本発明の減圧乾燥/炭化装置においては、更に、下記各態様とすることが可能である。   In the reduced-pressure drying / carbonization apparatus of the present invention, the following embodiments can be further provided.

なお、本発明の減圧乾燥/炭化装置を、方法の発明として記載すると、下記構成となる。   In addition, if the vacuum drying / carbonization apparatus of this invention is described as invention of a method, it will become the following structure.

最良の実施形態の一つを、図1〜2に基づいて説明する。先ず、該略を述べる。   One of the best embodiments will be described with reference to FIGS. First, the abbreviation will be described.
ジャケット構造の減圧乾燥/炭化装置であり、乾燥炭化室1とジャケット部15で形成される熱気発生/加熱炉5を備えたものである。   This is a vacuum drying / carbonization apparatus having a jacket structure, and includes a hot air generation / heating furnace 5 formed by a drying carbonization chamber 1 and a jacket portion 15.
乾燥/炭化室2の形状は、竪型及び横型の円筒形状及び逆かまぼこ形状のものがよく、内部を攪拌混合する横型の攪拌機3(混合手段)を有する。ジャケット構造の下部には熱気発生/加熱炉5を有し、該熱気発生/加熱炉5は、熱気発生部(熱風発生部)5a及び熱気ガイド部5bを備えている。そして、熱気発生部5aは、熱気熱源としてバーナ6を備えている。更に、前記乾燥/炭化室2と熱気発生部5aとは、ガス配管(連結配管)14により接続され、ガス配管14のガス出口、すなわち、熱風発生部5bのガス入り口は、エアエジェクタ8(減圧噴射手段)を介して、熱気発生部熱5bに臨んでエジェクタ吐出口(噴射口)9とされている。   The drying / carbonization chamber 2 may have a vertical and horizontal cylindrical shape and a reverse kamaboko shape, and has a horizontal stirrer 3 (mixing means) for stirring and mixing the inside. A hot air generation / heating furnace 5 is provided at the lower part of the jacket structure, and the hot air generation / heating furnace 5 includes a hot air generation part (hot air generation part) 5a and a hot air guide part 5b. And the hot air generation part 5a is provided with the burner 6 as a hot air heat source. Further, the drying / carbonization chamber 2 and the hot air generating section 5a are connected by a gas pipe (connecting pipe) 14, and a gas outlet of the gas pipe 14, that is, a gas inlet of the hot air generating section 5b is connected to an air ejector 8 (decompression pressure). The ejector discharge port (injection port) 9 faces the hot air generating part heat 5b via the injection means).
こうして、エアエジェクタ8により強制減圧され、引き込まれた空気、被処理物に加えられた間接加熱により発生する蒸発蒸気、ガスを熱気発生/加熱炉5に高温のまま導入でき、再加熱されることにより、熱気発生/加熱炉5の熱気発生部5aで、過熱化又は熱分解皿には燃やされて熱気(熱風や過熱蒸気や過熱分解ガス)となり、より効率よく、乾燥や炭化を行えるようになっている。   In this way, the air is ejected by the air ejector 8 and the drawn-in air, the evaporated vapor generated by the indirect heating applied to the object to be processed, and the gas can be introduced into the hot air generation / heating furnace 5 at a high temperature and reheated. Thus, in the hot air generation / heating furnace 5 of the hot air generation / heating furnace 5, the superheated or pyrolysis dish is burned and becomes hot air (hot air, superheated steam, or superheated decomposition gas) so that drying and carbonization can be performed more efficiently. It has become.
以下、図1〜2に基づいてさらに詳細に説明をする。   Hereinafter, a more detailed description will be given based on FIGS.
外壁の内側又は外側が断熱加工された減圧乾燥炭化装置1で、装置1内に乾燥/炭化室2が設置され、乾燥/炭化室2の内部には、回転可能な横型の攪拌機3(混合手段)が耐熱軸受4に軸支されて装着(配設)されている。軸受4は、パッキンを介して、外気とは遮断された構造である。乾燥/炭化室2の周面には、熱気発生/加熱炉5がジャケット状(覆うように)に形成されている。該熱気発生/加熱炉5の乾燥/炭化室2の下面側は、熱気発生部5aとされ、該熱気発生部5aには、熱気熱源であるバーナ6が配されている。   A vacuum drying carbonization apparatus 1 whose inside or outside of the outer wall is heat-insulated. A drying / carbonization chamber 2 is installed in the apparatus 1, and a rotatable horizontal stirrer 3 (mixing means) is installed inside the drying / carbonization chamber 2. ) Is mounted (arranged) by being supported by the heat-resistant bearing 4. The bearing 4 has a structure that is shielded from the outside air via a packing. On the peripheral surface of the drying / carbonizing chamber 2, a hot air generating / heating furnace 5 is formed in a jacket shape (so as to cover it). The lower surface side of the drying / carbonizing chamber 2 of the hot air generation / heating furnace 5 is a hot air generation unit 5a, and a burner 6 serving as a hot air heat source is disposed in the hot air generation unit 5a.
熱気発生部5aのガス入口は、減圧手段としてのエアエジェクタ8の吐出口9で形成されており、エアエジェクタ8の駆動流体(第1流体)のエアを発生する送風機10を運転(稼動)することにより、乾燥/炭化室2内の空気や被処理物より発生する水分、ガスは、乾燥/炭化室2のガス出口12より吸引され、乾燥/炭化室2は減圧される。   The gas inlet of the hot air generator 5a is formed by a discharge port 9 of an air ejector 8 as decompression means, and operates (operates) a blower 10 that generates air as a driving fluid (first fluid) of the air ejector 8. Thus, moisture and gas generated from the air in the drying / carbonization chamber 2 and the object to be processed are sucked from the gas outlet 12 of the drying / carbonization chamber 2 and the drying / carbonization chamber 2 is decompressed.
吸引された空気、蒸発蒸気、ガスは熱気発生/加熱炉5へガス配管(連結配管)14を経て高温のまま導入され、バーナ6(熱気熱源)の火炎にて再加熱により、過熱化されて過熱ガス及び熱分解ガスさらには燃やされて燃焼ガスからなる熱気となって、乾燥・炭化(乾留)の加熱源である熱気の加熱エネルギーを増大させる。   The sucked air, vaporized vapor, and gas are introduced into the hot air generation / heating furnace 5 through the gas pipe (connecting pipe) 14 at a high temperature and reheated by the flame of the burner 6 (hot air heat source). Superheated gas, pyrolysis gas, and further burned to become hot air consisting of combustion gas, increasing the heating energy of hot air, which is a heating source for drying and carbonization (dry distillation).
該熱気(熱風、過熱ガス、熱分解ガス、燃焼ガス)は、乾燥/炭化室2と装置の外壁とで形成されたジャケット部15で形成された熱気ガイド部5bを通り内部の被処理物11を間接加熱する。ジャケット部で形成される熱気ガイド部(熱気通路)5bは、ショートパスを防ぐためバッフル(邪魔板、案内板)16が設けられている。こうして、熱気17は、乾燥/炭化室2の外周を回り排気筒18から排気される。排気筒18には、排気ダンパ20が付設されている。該排気ダンパ20は、熱風流量を制御(コントロール)することにより、熱気発生/加熱炉5内の温度・風圧を制御する。被処理物11は、原料投入口21から投入され、されに、攪拌機3のパドル(攪拌羽根)22にて攪拌されることにより、均一に加熱される。攪拌機3は、減速駆動モータ23にて回転駆動される。なお、攪拌機3のパドル(攪拌羽根)22は、攪拌機3の回転方向によって、粉粒体の軸方向に搬送(移送)が可能となっている。こうして、被処理物の処理品(処理済物:乾燥物、炭化物)は、攪拌機3の回転により、排出口24より排出される。   The hot air (hot air, superheated gas, pyrolysis gas, combustion gas) passes through the hot air guide part 5b formed by the jacket part 15 formed by the drying / carbonization chamber 2 and the outer wall of the apparatus, and the workpiece 11 inside. Indirect heating. The hot air guide portion (hot air passage) 5b formed by the jacket portion is provided with a baffle (baffle plate, guide plate) 16 to prevent a short path. Thus, the hot air 17 travels around the outer periphery of the drying / carbonization chamber 2 and is exhausted from the exhaust cylinder 18. An exhaust damper 20 is attached to the exhaust cylinder 18. The exhaust damper 20 controls the temperature and wind pressure in the hot air generation / heating furnace 5 by controlling the flow rate of hot air. The workpiece 11 is charged from the raw material inlet 21 and is stirred uniformly by the paddle (stirring blade) 22 of the stirrer 3 so that it is uniformly heated. The stirrer 3 is rotationally driven by a deceleration drive motor 23. In addition, the paddle (stirring blade) 22 of the stirrer 3 can be conveyed (transferred) in the axial direction of the granular material depending on the rotation direction of the stirrer 3. Thus, the processed product (processed product: dry product, carbide) is discharged from the discharge port 24 by the rotation of the stirrer 3.
また、処理品36の排出は、図3に示すような構成としてもよい。図3では、熱気熱源として、バーナの代わりに電熱ヒータ7を使用している。電熱ヒータ7は、ヒータ保護管34で保護されている。   Further, the discharge of the processed product 36 may be configured as shown in FIG. In FIG. 3, an electric heater 7 is used as a hot air heat source instead of the burner. The electric heater 7 is protected by a heater protection tube 34.
攪拌機3の回転軸3aを中空シャフトとし、該中空シャフト3aの処理物搬送方向の一端に吸引パイプ3bが連結され、吸引パイプ3bの開口端が処理物吸引口27とされている。そして、中空シャフト3aの処理物排出側は、ロータリジョイント26を介して、真空吸引器(バキューマー、集塵機又は掃除機)25と連結された真空吸引配管(処理物搬送配管)37に接続されている。真空吸引配管37は、バルブ35を備えている。この構成の場合、攪拌パドル22の搬送作用を利用すれば全量吸引することができる。   The rotating shaft 3a of the stirrer 3 is a hollow shaft, and a suction pipe 3b is connected to one end of the hollow shaft 3a in the processed product conveyance direction, and the open end of the suction pipe 3b is a processed product suction port 27. The processed product discharge side of the hollow shaft 3a is connected to a vacuum suction pipe (processed product transport pipe) 37 connected to a vacuum suction device (vacuumer, dust collector or vacuum cleaner) 25 via a rotary joint 26. . The vacuum suction pipe 37 includes a valve 35. In the case of this configuration, the entire amount can be sucked by using the conveying action of the stirring paddle 22.
処理品36の冷却は連結配管(ガス配管)14に付設されたバルブ29を閉じて、送風機10にて送風冷却すればよい。運転時の安全対策は、送風機10の停止には逆止弁30の作用によって熱気(熱風)の逆流が阻止でき、乾燥/炭化室2が異常内圧となったときは、安全弁31にて圧を逃がすことができるようになっている。   The processing product 36 may be cooled by closing the valve 29 attached to the connecting pipe (gas pipe) 14 and cooling with the blower 10. As a safety measure during operation, when the blower 10 is stopped, the check valve 30 can prevent the backflow of hot air (hot air), and when the drying / carbonization chamber 2 has an abnormal internal pressure, the safety valve 31 applies the pressure. It can be escaped.
乾燥/炭化装置1の材質は、耐熱性ステンレス鋼が望ましく、断熱材は、セラミックファイバー耐火材、珪酸カルシウム保温材、ロックウール保存材等が、軽量であり施工に適している。なお、耐火レンガ又は耐火キャスタでもよいが重量が増加する。   The material of the drying / carbonizing apparatus 1 is preferably heat-resistant stainless steel, and the heat insulating materials such as ceramic fiber refractory material, calcium silicate heat insulating material, rock wool preservation material, etc. are lightweight and suitable for construction. In addition, although a refractory brick or a refractory caster may be sufficient, a weight increases.
乾燥/炭化室2内の減圧度は、例えば、−1.33〜−5.33kPa(−100〜−400mmHg)とすれば、沸点(水の場合)約96〜80℃となる。この減圧度を得るには、エアエジェクタ8の運転条件は、20〜150kPa、吐出量2〜20m3/minとする。 If the decompression degree in the drying / carbonization chamber 2 is, for example, −1.33 to −5.33 kPa (−100 to −400 mmHg), the boiling point (in the case of water) is about 96 to 80 ° C. In order to obtain this degree of decompression, the operating conditions of the air ejector 8 are 20 to 150 kPa, and the discharge rate is 2 to 20 m 3 / min.
バーナ6の燃料は、灯油、重油、都市ガス、LPG等とする。そして、熱気発生/加熱炉5内の温度は、熱気発生/加熱炉5内に、熱気発生部5a近傍に付設された温度センサ32及び乾燥/炭化室2内に付設された温度センサ33からの検知信号により燃料供給量を制御(コントロール)して、所定の温度に維持する。   The fuel for the burner 6 is kerosene, heavy oil, city gas, LPG, or the like. The temperature in the hot air generation / heating furnace 5 is derived from the temperature sensor 32 provided in the vicinity of the hot air generation unit 5a and the temperature sensor 33 provided in the drying / carbonization chamber 2 in the hot air generation / heating furnace 5. The fuel supply amount is controlled (controlled) by the detection signal and maintained at a predetermined temperature.
また、図3に示すような電熱ヒータ7の場合は、複数本のヒータ7を設置しておき、それらのヒータ7を適宜、通電、遮断を繰り返して温度制御をする。   In the case of an electric heater 7 as shown in FIG. 3, a plurality of heaters 7 are installed, and temperature control is performed by repeatedly energizing and shutting off the heaters 7 as appropriate.
ヒータ7の種類は、鋳込みヒータ、パイプヒータ、カートリッジヒータ等がよくカートリッジヒータの場合は、ヒータ保護管34を使用すれば寿命も長くすることができる。   As the type of the heater 7, a cast heater, a pipe heater, a cartridge heater, and the like are good, and in the case of a cartridge heater, the life can be extended by using the heater protection tube 34.
また、乾燥/炭化室2の攪拌機3の回転数は、1〜15rpm(平均周速3〜45m/min)程度とする。したがって、攪拌機の駆動は、低動力、高トルクモータ23ですむ。   Moreover, the rotation speed of the stirrer 3 of the drying / carbonization chamber 2 is about 1 to 15 rpm (average peripheral speed of 3 to 45 m / min). Therefore, the agitator can be driven by a low power, high torque motor 23.
次に、上記実施形態の使用態様を説明する。   Next, usage modes of the above embodiment will be described.
本発明は、被処理物によって、乾燥装置として、又は炭化装置として、使い分けることが可能となる。   The present invention can be properly used as a drying apparatus or as a carbonization apparatus depending on the object to be processed.
すなわち、オカラ、野菜くずのような食品残渣等を飼料として、又は、生ごみ、汚泥等を肥料として再利用する場合は乾燥装置として使用可能である一方、飼料や肥料にはならない可燃性有機廃棄物等は、炭化装置として使用できる。乾燥装置として使用する場合、乾燥化室内の温度センサの温度によって乾燥終点がわかる。   That is, it can be used as a drying device when food residues such as okara and vegetable waste are used as feed, or when garbage, sludge, etc. are reused as fertilizer, while flammable organic waste that does not become feed or fertilizer A thing etc. can be used as a carbonization apparatus. When used as a drying device, the end point of drying is determined by the temperature of the temperature sensor in the drying chamber.
エアエジェクタ8等にて減圧された乾燥/炭化室1内は、被処理物(含液有機廃棄物)の水分があるうちは温度センサが示す表面温度は、通常、85℃前後であるが、水分が蒸発してなくなった時点で温度が上昇しはじめる。温度が90℃程度に上昇したとき、熱気熱源6を停止し、ガス配管(連通配管)14のバルブ29を閉じて送風機10にて冷却してやれば、おおむね含水率7〜15%程度の乾燥処理品を得ることができる。   In the drying / carbonization chamber 1 decompressed by the air ejector 8 or the like, the surface temperature indicated by the temperature sensor is usually around 85 ° C. while the moisture of the object to be treated (liquid-containing organic waste) is present. The temperature begins to rise when the water has evaporated. When the temperature rises to about 90 ° C., if the hot air heat source 6 is stopped, the valve 29 of the gas pipe (communication pipe) 14 is closed and cooled by the blower 10, the dried product with a moisture content of about 7 to 15% is generally obtained. Can be obtained.
そして、被処理物の炭化品(乾留品)を得ようとする場合は、乾燥/炭化室の温度センサ33の表示温度が250℃程度で良質な炭化物(乾留物)を得ることができる。   When carbonized products (distilled products) to be processed are to be obtained, good quality carbides (distilled products) can be obtained at a display temperature of the temperature sensor 33 in the drying / carbonization chamber of about 250 ° C.
被処理物を乾燥/炭化室1に投入しバーナ6(熱気熱源)にて加熱し、エアエジェクタ8にて乾燥/炭化室内を減圧すれば、当初、乾燥/炭化室1内の空気を熱気発生/加熱炉5に引き込む(吸引する)。該吸引されたエアは、バーナ6(熱気熱源)と接触して熱気となり、ジャケット部15(熱気ガイド部)に沿って、乾燥/炭化室1を加熱(熱交換)をしながら上昇して、排気筒19を経て排気される。こうして、乾燥/炭化室1内の被処理物が加熱されて、水分の蒸発が起き、その蒸発蒸気が、熱気発生/加熱炉5へ、吸引導入され、過熱蒸気(熱気)となり、より多くの熱が、効率よく被処理物に加えられる。それにより、蒸発も促進され、相乗効果が期待できる。   If the workpiece is put into the drying / carbonization chamber 1 and heated by the burner 6 (hot air heat source), and the drying / carbonization chamber is depressurized by the air ejector 8, the air in the drying / carbonization chamber 1 is initially generated as hot air. / Pull into the furnace 5 (suction). The sucked air comes into contact with the burner 6 (hot air heat source) and becomes hot air, and rises while heating (heating exchange) the drying / carbonizing chamber 1 along the jacket portion 15 (hot air guide portion), The exhaust is exhausted through the exhaust cylinder 19. In this way, the object to be treated in the drying / carbonization chamber 1 is heated to cause evaporation of moisture, and the evaporated vapor is sucked into the hot air generation / heating furnace 5 to become superheated steam (hot air), and more Heat is efficiently applied to the workpiece. Thereby, evaporation is also promoted and a synergistic effect can be expected.
他方、乾燥装置として使用する場合は、熱気発生/加熱炉1内の温度センサ32の温度を400〜500℃程度に保つように、バーナ6(熱気熱源)の運転をコントロールしてやれば、非常に省エネで処理することができる。   On the other hand, when used as a drying device, if the operation of the burner 6 (hot air heat source) is controlled so as to keep the temperature of the temperature sensor 32 in the hot air generation / heating furnace 1 at about 400 to 500 ° C., it is very energy saving. Can be processed.
また、本発明の減圧乾燥/炭化装置は、上記の如く、中温(800℃以下)で運転するため、高温運転装置に比べて、耐久性が向上する。   Moreover, since the reduced-pressure drying / carbonization apparatus of the present invention operates at an intermediate temperature (800 ° C. or lower) as described above, the durability is improved as compared with a high-temperature operation apparatus.
含液有機廃棄物(被処理物)の水分が蒸発し、さらに加熱すると次に乾留ガスが発生する。この乾留ガスがエアエジェクタ8により吸引され、熱気発生/加熱炉5へ導入され、熱分解ガス又は燃料となり、より加熱効果(火力:加熱エネルギー量)が増大(上昇)する。   The water content of the liquid organic waste (object to be treated) evaporates, and when heated further, dry distillation gas is generated. The dry distillation gas is sucked by the air ejector 8 and introduced into the hot air generation / heating furnace 5 to become pyrolysis gas or fuel, and the heating effect (thermal power: amount of heating energy) is further increased (increased).
熱気発生/加熱炉5内の温度は、400〜500℃程度で運転してもよいが、炭化(乾留)の場合は乾燥/炭化室内の温度を250℃程度まで上昇させなければならないため800℃程度まで温度を上げて運転すれば、時間を短縮することができ、さらには、ダイオキシンの発生の抑制も期待できる。   The hot air generation / heating furnace 5 may be operated at a temperature of about 400 to 500 ° C. However, in the case of carbonization (dry distillation), the temperature in the drying / carbonization chamber must be increased to about 250 ° C., so that the temperature is 800 ° C. If the temperature is raised to a certain level, the time can be shortened, and further, suppression of dioxin generation can be expected.
乾燥/炭化室2内の攪拌機3にて攪拌(混合)することにより、被処理物に均一に熱を加えることができ、処理品に出来上がりむらが発生することもなく、減圧させることにより沸点も下がり、蒸発効率が上昇して、結果的に熱効率も向上する(省エネとなる。)。   By stirring (mixing) with the stirrer 3 in the drying / carbonizing chamber 2, heat can be uniformly applied to the object to be processed, and there is no unevenness in the finished product, and the boiling point can be reduced by reducing the pressure. Decreasing and evaporating efficiency increases, resulting in improved thermal efficiency (energy saving).
また、減圧されて吸引されたガス(気体)(空気、蒸発蒸気、乾留ガス)を熱気発生/加熱炉5に導き、バーナ6(熱気熱源:接触加熱器)により過熱化することにより、よりよく熱効率をあげつつ乾燥と炭化を行うことができる。   In addition, gas (gas) (air, vaporized vapor, dry distillation gas) that has been decompressed and sucked into the hot-air generator / heating furnace 5 is superheated by a burner 6 (hot-air heat source: contact heater). Drying and carbonization can be performed while increasing thermal efficiency.
被処理物が持つ水分や揮発性有機質を内部から減圧して引き出すことにより、炭化の場合、賦活処理をしている状態と同じ状態になり、低温でも良好な細孔を持った炭化品(乾留品)が得られ、活性炭等としても利用が可能となる。   In the case of carbonization, the moisture and volatile organic matter of the object to be processed are extracted from the inside by reducing the pressure, and in the case of carbonization, it becomes the same state as the activation treatment state, and carbonized products with good pores (dry distillation) even at low temperatures Product) and can be used as activated carbon.
また、使用済み活性炭の場合、吸着物質は有機質であるため、本発明の装置にて熱分解処理をすれば、活性炭の再生も可能となり、活性炭の再生装置としても利用できる。   Further, in the case of used activated carbon, the adsorbed substance is organic. Therefore, if the pyrolysis treatment is performed in the apparatus of the present invention, the activated carbon can be regenerated and can be used as a regenerated apparatus for activated carbon.
本発明装置を使用して処理を行った乾燥品は、飼料、肥料等にリサイクルすることができ、また、炭化物は、燃料、土壌改良剤、調湿剤、ろ過剤、融雪剤、堆肥等に利用することができる。   The dried product processed using the apparatus of the present invention can be recycled into feed, fertilizer, etc., and the carbide can be used as fuel, soil conditioner, humidity conditioner, filter agent, snow melting agent, compost, etc. Can be used.
また、二次公害を発生することなく低温での処理ができ、したがって耐久性も増大し操作が簡単で、運転技術者も不要、危険性も無く安全で、自動運転ができ、安価な装置である。   In addition, it can be processed at low temperatures without causing secondary pollution, and therefore it has increased durability and is easy to operate, requires no driving engineer, is safe without danger, can be operated automatically, and is inexpensive. is there.
自動運転の場合は、温度センサを管理して、バーナやヒータの運転を停止し、排気ダンパの開閉をコントロール(制御)してやれば完全自動運転ができる。   In the case of automatic operation, if the temperature sensor is managed, the operation of the burner or the heater is stopped, and the opening / closing of the exhaust damper is controlled (controlled), the fully automatic operation can be performed.
