Description

本発明は、有機系固形物処理装置に関する。   The present invention relates to an organic solid material processing apparatus.

例えば特開２００２−１１３４４４号公報には、食品廃棄物、農業・畜産廃棄物あるいは漁業廃棄物等の有機系廃棄物を蒸気分解する技術が開示されている。この従来技術は、ボイラで発生した水蒸気を反応器に供給することにより当該反応器内の有機系廃棄物を蒸気分解するものであり、当該蒸気分解によって生成された分解物に各種の処理を施すことにより、分解物中の液体成分から液体肥料を分離したり、分解物中の固形成分から肥料や固形燃料を生成するものである。このような従来技術では、蒸気分解の反応器において有機系廃棄物の蒸気分解と同時に減菌処理及び不捻化処理を行うので、上記各肥料や固形燃料に別途減菌処理及び不捻化処理を行う必要がなく、有機系廃棄物の処理工程が簡単化される。
また、上記従来技術は、有機系廃棄物を蒸気分解するものであるが、この他に有機系廃棄物の処理方法として超臨界水を用いた水熱処理が知られている。
特開２００２−１１３４４４号公報 For example, Japanese Patent Application Laid-Open No. 2002-113444 discloses a technique for steam-decomposing organic waste such as food waste, agricultural / livestock waste, or fishery waste. This prior art is for steam decomposition of organic waste in the reactor by supplying steam generated in the boiler to the reactor, and various treatments are performed on the decomposition product generated by the steam decomposition. Thus, the liquid fertilizer is separated from the liquid component in the decomposition product, or the fertilizer and the solid fuel are generated from the solid component in the decomposition product. In such a conventional technique, the sterilization treatment and the sterilization treatment are performed simultaneously with the steam decomposition of the organic waste in the steam decomposition reactor. It is not necessary to perform the process, and the organic waste treatment process is simplified.
Moreover, although the said prior art is what carries out vapor decomposition | disassembly of organic waste, the hydrothermal treatment using supercritical water is also known as a processing method of organic waste besides this.
JP 2002-113444 A

ところで、上述した蒸気分解処理や水熱処理は有機系廃棄物を水蒸気や超臨界水雰囲気下で分解処理するものであり、処理が完了した処理物の固形成分は多量の水分を含んでいる。このような固形成分から上述した肥料や固形燃料を生成するためには固形成分を乾燥させる必要があるが、この乾燥のためには新たな動力が必要であり、この乾燥処理は、有機系廃棄物の処理に係るエネルギー効率を低下させる、つまり処理コストを上昇させる１つの要因となっている。   By the way, the above-described steam decomposition treatment and hydrothermal treatment are those in which organic waste is decomposed in an atmosphere of water vapor or supercritical water, and the solid component of the processed product contains a large amount of moisture. In order to produce the above-mentioned fertilizer and solid fuel from such a solid component, it is necessary to dry the solid component. However, for this drying, new power is required, and this drying process is an organic waste. This is one factor that lowers the energy efficiency related to the processing of an object, that is, increases the processing cost.

本発明は、上述した事情に鑑みてなされたものであり、以下の点を目的とするものである。
（１）有機系固形物の処理に係るエネルギー効率を従来よりも向上させる。
（２）有機系固形物の処理コストを従来よりも低減する。 The present invention has been made in view of the above-described circumstances, and has the following objects.
(1) The energy efficiency related to the treatment of organic solids is improved as compared with the prior art.
(2) The processing cost of the organic solid is reduced as compared with the conventional method.

上記目的を達成するために、本発明では、高温高圧の液体あるいは気体を用いて有機系固形物に所定処理を施す処理容器と、該処理容器から処理後に排出される高温高圧の排ガスを用いて有機系固形物の処理物を攪拌する攪拌手段とを具備する、という解決手段を採用する。   In order to achieve the above object, the present invention uses a processing container for performing a predetermined treatment on an organic solid using a high-temperature and high-pressure liquid or gas, and a high-temperature and high-pressure exhaust gas discharged after the treatment from the processing container The solution means which comprises the stirring means which stirs the processed material of organic type solid substance is employ | adopted.

本発明によれば、高温高圧の排ガスが有するエネルギーを利用して処理物を攪拌するので、特に動力を用いることなく処理物を解したりあるいは乾燥させることができる。   According to the present invention, since the processed material is stirred using the energy of the high-temperature and high-pressure exhaust gas, the processed material can be unwound or dried without using power.

以下、図面を参照して、本発明の実施形態について説明する。なお、本実施形態は有機系固形物を蒸気分解するタイプの有機系固形物処理装置に関する。

有機系固形物Ｘは、食品廃棄物、農業・畜産廃棄物あるいは漁業廃棄物等であり、より具体的には刈草や剪定枝あるいは廃木材である。このような有機系固形物Ｘは、ウッドチッパ等によって予め細かく裁断されたものである。処理容器１は、一種の圧力容器であり、給気弁３を介して蒸気ボイラ２から供給された水蒸気によって有機系固形物Ｘを蒸気分解する。   The organic solid X is food waste, agriculture / livestock waste, fishery waste, or the like, and more specifically cut grass, pruned branches, or waste wood. Such organic solid X is finely cut in advance by a wood chipper or the like. The processing container 1 is a kind of pressure container, and vaporizes the organic solid X with water vapor supplied from the steam boiler 2 via the air supply valve 3.

この処理容器１は、側部が開閉ドアになっており、上記有機系固形物Ｘを開閉ドアを介して側方から内部に収容する横型処理容器である。また、処理容器１の床部にはノズル付載置台１ａ（吹付手段）が設けられており、蒸気有機系固形物Ｘは、当該ノズル付載置台１ａ上に載置された状態で処理容器１内に収容される。   This processing container 1 is a horizontal processing container in which the side part is an open / close door and accommodates the organic solid material X from the side through the open / close door. Moreover, the mounting base 1a (spraying means) is provided on the floor of the processing container 1, and the vapor organic solid X is placed on the mounting base 1a with the nozzle in the processing container 1. Housed inside.

このノズル付載置台１ａは、下側から上側（上記有機系固形物Ｘ側）に貫通する１個あるいは多数のノズル孔が形成されると共に、第２開閉弁９を介して処理容器１内に取り込まれた排ガスが下側に供給されるように構成されている。ここで、上述した各構成要素のうち、第１開閉弁７、圧力容器８、第２開閉弁９及びノズル付載置台１ａは、本第１実施形態における攪拌手段を構成している。 The nozzle-equipped mounting table 1 a is formed with one or a plurality of nozzle holes penetrating from the lower side to the upper side (the organic solid material X side), and in the processing container 1 through the second on-off valve 9. The taken-in exhaust gas is configured to be supplied to the lower side. Here, among the constituent elements described above, the first on-off valve 7, the pressure vessel 8, the second on-off valve 9, and the mounting table with nozzle 1a constitute the stirring means in the first embodiment.

蒸気ボイラ２は、水蒸気を発生させ、給気弁３を介して上記処理容器１に供給する。給気弁３は、水蒸気の処理容器１への供給を制御する制御弁である。この給気弁３の開閉によって水蒸気の処理容器１への供給量が調節されて処理容器１内の温度及び圧力つまり蒸気分解の処理条件が所定条件に設定される。安全弁４は、処理容器１内が異常圧力となったときに開状態となって処理容器１を保護する。圧力計５は、処理容器１の内圧つまり処理容器１内における蒸気分解の圧力を計測する。   The steam boiler 2 generates water vapor and supplies it to the processing container 1 through the air supply valve 3. The air supply valve 3 is a control valve that controls the supply of water vapor to the processing container 1. The supply amount of water vapor to the processing container 1 is adjusted by opening and closing the air supply valve 3, and the temperature and pressure in the processing container 1, that is, the processing conditions for steam decomposition are set to predetermined conditions. The safety valve 4 is opened when the inside of the processing container 1 becomes abnormal pressure, and protects the processing container 1. The pressure gauge 5 measures the internal pressure of the processing container 1, that is, the pressure of steam decomposition in the processing container 1.

排気弁６は、処理容器１における蒸気分解後の排ガスを外部に排出するために処理容器１に付随して設けられた配管の途中部位に備えられている。第１開閉弁７は、処理容器１と圧力容器８とを接続する配管の途中部位に設けられており、処理容器１における蒸気分解後の排ガスの圧力容器８への供給／停止を規定する。圧力容器８は、排ガスを一時的に貯める。第２開閉弁９は、上記圧力容器８とノズル付載置台１ａとの連結する配管の途中部位に設けられており、圧力容器８内に貯留された排ガスのノズル付載置台１ａへの供給／停止を規定する。ドレイン排出弁１０は、圧力容器８内に溜まった液体成分を外部に排出するためのものである。   The exhaust valve 6 is provided at an intermediate portion of a pipe provided along with the processing container 1 in order to discharge the exhaust gas after steam decomposition in the processing container 1 to the outside. The first on-off valve 7 is provided at an intermediate portion of the pipe connecting the processing container 1 and the pressure container 8, and regulates supply / stop of the exhaust gas after steam decomposition in the processing container 1 to the pressure container 8. The pressure vessel 8 temporarily stores exhaust gas. The second on-off valve 9 is provided at an intermediate portion of the pipe connecting the pressure vessel 8 and the nozzle-equipped mounting table 1a, and the exhaust gas stored in the pressure vessel 8 is supplied to the nozzle-equipped mounting table 1a. Specify stop. The drain discharge valve 10 is for discharging the liquid component accumulated in the pressure vessel 8 to the outside.

なお、図１では、本有機系固形物処理装置の制御構成については省略している。本有機系固形物処理装置には実際は制御装置が付随しており、この制御装置は、圧力計５の測定値に基づいて処理容器１内で生じる蒸気分解の処理条件が所定条件となるように給気弁３を制御すると共に、排気弁６、第１開閉弁７、第２開閉弁９及びドレイン排出弁１０の開閉を処理状況に応じて制御する。 In FIG. 1, the control configuration of the organic solid material processing apparatus is omitted. The present organic solid material processing apparatus is actually accompanied by a control device, and this control device is configured so that the processing conditions of the steam decomposition generated in the processing container 1 based on the measurement value of the pressure gauge 5 become a predetermined condition. The air supply valve 3 is controlled, and the opening / closing of the exhaust valve 6 , the first opening / closing valve 7, the second opening / closing valve 9, and the drain discharge valve 10 is controlled according to the processing status.

次に、このように構成された有機系固形物処理装置の動作について説明する。
本有機系固形物処理装置では、有機系固形物Ｘの処理容器１への収容が完了すると、所定の処理時間に亘る分解処理が開始される。すなわち、制御装置によって排気弁６、第１開閉弁７、第２開閉弁９及びドレイン排出弁１０が閉状態とされて処理容器１内が密閉状態とされる一方、給気弁３が開状態とされることによって処理容器１内に蒸気ボイラ２の水蒸気が供給されて、処理容器１内における蒸気分解の処理条件が所定条件に設定される。この所定条件は、分解圧力が例えば１．０〜１．７ＭＰａ程度である。 Next, the operation of the organic solid material processing apparatus configured as described above will be described.
In the present organic solid material processing apparatus, when the organic solid material X is completely accommodated in the processing container 1, the decomposition processing over a predetermined processing time is started. That is, the exhaust valve 6 , the first on-off valve 7, the second on-off valve 9, and the drain discharge valve 10 are closed by the control device, and the inside of the processing container 1 is sealed, while the supply valve 3 is open. As a result, the steam in the steam boiler 2 is supplied into the processing container 1, and the processing conditions for steam decomposition in the processing container 1 are set to predetermined conditions. The predetermined condition is that the decomposition pressure is, for example, about 1.0 to 1.7 MPa.

このような所定条件下において有機系固形物Ｘが所定の処理時間に亘って蒸気分解されると、最初に第１開閉弁７が所定時間だけ開状態とされて所定量の排ガスが圧力容器８内に貯えられ、その後排気弁６が開状態とされて残りの排ガスが大気に放出される。続いて、第２開閉弁９が開状態とされて圧力容器８内の排ガスがノズル付載置台１ａに供給される。 When the organic solid X is vapor-decomposed over a predetermined processing time under such predetermined conditions, the first on-off valve 7 is first opened for a predetermined time, and a predetermined amount of exhaust gas is discharged from the pressure vessel 8. Then, the exhaust valve 6 is opened and the remaining exhaust gas is released to the atmosphere. Then, the 2nd on-off valve 9 is made into an open state, and the exhaust gas in the pressure vessel 8 is supplied to the nozzle mounting base 1a.

ここで、水蒸気分解後の処理容器１内は高温・高圧状態になっており、排ガスは高い圧力を有している。したがって、圧力容器８内にはこのような排ガスが高圧のまま貯えられる。一方、処理容器１は、排気弁６が開状態とされて残りの排ガスが大気に放出されたことによって大気圧状態となっている。このような圧力状態において、第２開閉弁９が開状態とされて圧力容器８内の排ガスがノズル付載置台１ａに供給されると、当該排ガスは、ノズル付載置台１ａのノズル孔を通過して水蒸気分解後の有機系固形物（処理物）に勢い良く吹き付けられる。この結果、処理物は排ガスによって攪拌されて解されると共に、ある程度乾燥した状態となる。 Here, the inside of the processing vessel 1 after steam decomposition is in a high temperature / high pressure state, and the exhaust gas has a high pressure. Therefore, such exhaust gas is stored in the pressure vessel 8 at a high pressure. On the other hand, the processing container 1 is in an atmospheric pressure state when the exhaust valve 6 is opened and the remaining exhaust gas is released to the atmosphere. In such a pressure state, when the second on-off valve 9 is opened and the exhaust gas in the pressure vessel 8 is supplied to the mounting table with nozzle 1a, the exhaust gas passes through the nozzle hole of the mounting table with nozzle 1a. Then, it is sprayed vigorously on the organic solid (processed product) after steam decomposition. As a result, the treated product is agitated and exhausted by the exhaust gas, and is dried to some extent.

このような本有機系固形物処理装置によれば、上記分解処理後の排ガスを用いて処理物を攪拌することにより解したりあるいはある程度乾燥させるので、処理物を解したりあるいは乾燥するために要するエネルギーを節約することが可能である。すなわち、本有機系固形物処理装置によれば、有機系固形物Ｘの処理に係るエネルギー効率を従来よりも向上させることが可能なので、処理コストを従来よりも低減することができる。   According to the present organic solid material processing apparatus, the processed product is dissolved by stirring the exhaust gas after the decomposition treatment or is dried to some extent, so that the processed product is dissolved or dried. It is possible to save the energy required. That is, according to the present organic solid matter processing apparatus, the energy efficiency related to the processing of the organic solid matter X can be improved as compared with the conventional method, and thus the processing cost can be reduced as compared with the conventional method.

〔第２実施形態〕
図２は、本発明の第２実施形態に係る有機系固形物処理装置の概略構成図である。この図２に示すように、本有機系固形物処理装置は、処理容器１１、蒸気ボイラ１２、給気弁１３、排気弁１４及びドレイン排出弁１５から構成されている。 [Second Embodiment]
FIG. 2 is a schematic configuration diagram of an organic solid material processing apparatus according to the second embodiment of the present invention. As shown in FIG. 2, the organic solid material processing apparatus includes a processing container 11, a steam boiler 12, an air supply valve 13, an exhaust valve 14, and a drain discharge valve 15.

処理容器１１は、図１に示した処理容器１（横型処理容器）とは異なり、図２に示するように縦向きに設置される縦型処理容器である。この処理容器１１は、底部近傍にノズル付隔壁１１ａ（吹付手段かつ攪拌手段）が設けられることによって上側室１１ｂと下側室１１ｃとの２室に区画されている。有機系固形物Ｘは、このノズル付隔壁１１ａ上に載置される。ノズル付隔壁１１ａは、処理容器１１内を上記上側室１１ｂと下側室１１ｃとに区画すると共に、当該上側室１１ｂと下側室１１ｃとに連通する１個あるいは多数のノズル孔が形成されている。   Unlike the processing container 1 (horizontal processing container) shown in FIG. 1, the processing container 11 is a vertical processing container installed vertically as shown in FIG. The processing container 11 is divided into two chambers, an upper chamber 11b and a lower chamber 11c, by providing a partition wall 11a with a nozzle (a spraying means and a stirring means) in the vicinity of the bottom. The organic solid X is placed on the partition wall 11a with nozzle. The nozzle-equipped partition 11a divides the inside of the processing vessel 11 into the upper chamber 11b and the lower chamber 11c, and one or a plurality of nozzle holes communicating with the upper chamber 11b and the lower chamber 11c are formed.

蒸気ボイラ１２は、水蒸気を発生させ、給気弁１３を介して上記処理容器１１の上側室１１ｂに供給する。給気弁１３は、蒸気ボイラ１２と上側室１１ｂを接続する配管の途中部位に設けられた制御弁であり、処理容器１１への水蒸気の供給を制御する。この給気弁１３の開閉によって水蒸気の処理容器１１への供給量が調節されて処理容器１１内の温度及び圧力つまり蒸気分解の処理条件が所定条件に設定される。 The steam boiler 12 generates steam and supplies it to the upper chamber 11 b of the processing container 11 through the air supply valve 13. Intake valve 13 is a control valve provided in the middle portion of the pipe connecting the steam boiler 12 and the upper chamber 11 b, and controls the supply of steam into the processing chamber 11. The supply amount of water vapor to the processing container 11 is adjusted by opening and closing the air supply valve 13, and the temperature and pressure in the processing container 11, that is, the processing conditions for steam decomposition are set to predetermined conditions.

排気弁１４は、処理容器１１における蒸気分解後の排ガスを外部に排出するためのものであり、蒸気ノズル付隔壁１１ａによって２室に区画された処理容器１１において有機系固形物Ｘが収納された上側室１１ｂに設けられた配管の途中部位に備えられている。ドレイン排出弁１５は、処理容器１１の低部に溜まる液体成分を外部に排出するために、上記低部に接続された配管の途中部位に設けられている。この液体成分は、有機系固形物Ｘを蒸気分解することによって得られる有機系固形物Ｘの抽出液である。 The exhaust valve 14 is for discharging the exhaust gas after steam decomposition in the processing container 11 to the outside, and the organic solid matter X is stored in the processing container 11 partitioned into two chambers by the partition wall 11a with the steam nozzle. It is provided in the middle portion of the pipe provided in the upper chamber 11 b. The drain discharge valve 15 is provided at an intermediate portion of the pipe connected to the lower portion in order to discharge the liquid component accumulated in the lower portion of the processing container 11 to the outside. This liquid component is an extract of organic solid X obtained by vapor decomposition of organic solid X.

次に、このような構成の有機系固形物処理装置の動作について説明する。
この有機系固形物処理装置では、水蒸気が蒸気ボイラ１２から有機系固形物Ｘが収容された上側室１１ｂに供給されることによって、当該上側室１１ｂ内の有機系固形物Ｘが蒸気分解される。そして、この蒸気分解が一定時間に亘って行われる間に、水蒸気はノズル付隔壁１１ａのノズル孔を介して下側室１１ｃに浸入し、有機系固形物Ｘの分解処理が完了した時点では上側室１１ｂと下側室１１ｃとは同一雰囲気となっている。 Next, the operation of the organic solid material processing apparatus having such a configuration will be described.
In this organic solid processing apparatus, when the water vapor is supplied from the steam boiler 12 to the upper chamber 11b in which the organic solid X is accommodated, the organic solid X in the upper chamber 11b is vapor-decomposed. . And while this vapor decomposition is performed over a certain period of time, water vapor enters the lower chamber 11c through the nozzle holes of the partition wall 11a with the nozzle, and when the decomposition processing of the organic solid X is completed, the upper chamber is completed. 11b and the lower chamber 11c have the same atmosphere.

したがって、有機系固形物Ｘの分解処理が完了して排気弁１４が開放されて、上側室１１ｂ内が減圧すると、下側室１１ｃのガス（水蒸気及び分解ガスからなる排ガス）が下側室１１ｃと上側室１１ｂとの圧力差によって、ノズル付隔壁１１ａのノズル孔を介して上側室１１ｂに勢い良く吹き出される。ここで、有機系固形物Ｘの処理物（固形成分）はノズル付隔壁１１ａ上に載置されているので、蒸気ノズル孔を介して上側室１１ｂに勢い良く吹き出される水蒸気によって攪拌され、この結果解されると共にある程度乾燥される。   Therefore, when the decomposition processing of the organic solid X is completed and the exhaust valve 14 is opened and the inside of the upper chamber 11b is depressurized, the gas in the lower chamber 11c (exhaust gas composed of water vapor and decomposition gas) is separated from the lower chamber 11c. Due to the pressure difference with the side chamber 11b, the air is blown out vigorously to the upper chamber 11b through the nozzle holes of the partition wall 11a with nozzle. Here, since the processed product (solid component) of the organic solid X is placed on the partition wall 11a with the nozzle, it is stirred by the steam blown out vigorously into the upper chamber 11b through the steam nozzle hole. The result is understood and dried to some extent.

このような本有機系固形物処理装置によれば、上述した第１実施形態に係る本有機系固形物処理装置と同様に、上記分解処理後の排ガスを用いて処理物を攪拌して解したりあるいはある程度乾燥させるので処理物を解したりあるいは乾燥するのに要するエネルギーを節約することが可能であり、よって有機系固形物Ｘの処理に係るエネルギー効率を従来よりも向上させること、つまり処理コストを従来よりも低減することが可能である。   According to such an organic solid material processing apparatus, the processed material is stirred and dissolved using the exhaust gas after the decomposition treatment, similarly to the organic solid material processing apparatus according to the first embodiment described above. Or to some extent, it is possible to save the energy required to unravel the processed material or to dry it, and thus improve the energy efficiency related to the processing of the organic solid X, that is, the processing The cost can be reduced as compared with the conventional case.

なお、上述した各実施形態では有機系固形物Ｘを水蒸気を用いて蒸気分解する有機系固形物処理装置について説明したが、本発明はこれに限定されるものではない。本発明は、高温高圧の液体あるいは気体を用いて有機系固形物を処理する装置であれば適用可能であり、例えば超臨界水を用いて有機系固形物を水熱処理するタイプの有機系固形物処理装置にも適用可能である。   In addition, although each embodiment mentioned above demonstrated the organic-type solid-material processing apparatus which vapor-decomposes the organic-type solid substance X using water vapor | steam, this invention is not limited to this. The present invention is applicable to any apparatus that processes organic solids using high-temperature and high-pressure liquids or gases. For example, organic solids of the type in which organic solids are hydrothermally treated using supercritical water. It can also be applied to a processing apparatus.
