Description

本発明は、気体輸送の制御方法とその装置に関し、特に、設備全体のコンパクト化を図るとともに、高い輸送能力をもった気体輸送の制御方法とその装置に関するものである。   The present invention relates to a method and apparatus for controlling gas transportation, and more particularly, to a method and apparatus for controlling gas transportation having high transportation capacity while reducing the size of the entire facility.

粉粒体を空気流により輸送する装置としては、図２に示すように、粉粒体を蓄える貯留槽２と、該貯留槽２の下流側にゲートバルブ３及びインレットバルブ４をこの順に設け、ゲートバルブ３とインレットバルブ４とを開放し、貯留槽２内の粉粒体をトランスポータ６に一定量送り込み、ゲートバルブ３とインレットバルブ４とを閉鎖し、エアレシーバ７内の圧縮空気をブースタノズルＮＢ０を介して輸送管５内に送り、輸送管５の長さに応じて途中ブースタノズルＮＢ１、ＮＢ２・・・を配設することによって粉粒体を輸送先のサイロ（図示省略）に搬送する粉粒体の気体輸送装置１が知られている。   As an apparatus for transporting the granular material by air flow, as shown in FIG. 2, a storage tank 2 for storing the granular material, and a gate valve 3 and an inlet valve 4 are provided in this order on the downstream side of the storage tank 2, The gate valve 3 and the inlet valve 4 are opened, a certain amount of powder in the storage tank 2 is sent to the transporter 6, the gate valve 3 and the inlet valve 4 are closed, and the compressed air in the air receiver 7 is boosted. It is fed into the transport pipe 5 through the nozzle NB0 and the booster nozzles NB1, NB2,... Are arranged on the way according to the length of the transport pipe 5 to convey the granular material to a transport destination silo (not shown). There is known a gas transport device 1 for a granular material to be used.

ところで、この粉粒体の気体輸送装置１では、粉粒体の輸送方法として、大別すると周知のフルラインコンセプト輸送とコンベンショナルコンセプト輸送との２種類がある。
コンベンショナルコンセプト輸送の場合、貯留槽２に溜まった粉粒体を、ゲートバルブ３とインレットバルブ４を開放してトランスポータ６内に所定量蓄え、インレットバルブ４を閉鎖後に空気輸送を開始し、輸送管５内に粉粒体が残らない状態になるまで送りきるもので、トランスポータ６内の内圧が粉粒体を送りきったことによってほぼ無負荷状態となったことを検知して輸送を完了する。 By the way, in this granular material gas transport device 1, there are two types of methods for transporting the granular material: a well-known full-line concept transportation and a conventional concept transportation.
In the case of conventional concept transportation, the granular material collected in the storage tank 2 is stored in a predetermined amount in the transporter 6 by opening the gate valve 3 and the inlet valve 4, and air transportation is started after the inlet valve 4 is closed. The pipe 5 can be fed until no granular material remains, and the transporter 6 detects that the internal pressure in the transporter 6 has almost reached no load because the granular material has been completely delivered. To do.

そして、このコンベンショナルコンセプト輸送の場合、輸送圧力は低く抑えることができるとともに、輸送中の粉体速度も遅くできるため、長距離を安定して輸送することができるという利点がある一方、トランスポータ６内の粉粒体がほぼなくなる際の最終期には、粉体速度が上がることによって粉体形状が損傷したり輸送管５内面が摩耗する他、粉粒体を輸送管５内に残留させることなく送りきるため輸送用圧縮空気を大量に消費するといった問題があった。   In the case of this conventional concept transportation, the transportation pressure can be kept low, and the powder speed during transportation can be slowed. Therefore, there is an advantage that the long distance can be stably transported. In the final stage when the powder particles are almost gone, the powder shape is damaged or the inner surface of the transport pipe 5 is worn by increasing the powder speed, and the powder particles are left in the transport pipe 5. There is a problem that a large amount of compressed air for transportation is consumed.

また、フルラインコンセプト輸送の場合、トランスポータ６内に粉粒体がなくなったことをレベル計やロードセル（重量計）によって感知したときに粉粒体の輸送を一旦停止し、貯留槽２に必要な量の粉粒体が溜まったときにゲートバルブ３とインレットバルブ４を開放して、再度トランスポータ６に所定量の粉粒体を送り込み、輸送を再開する方式で、輸送用の圧縮空気の消費量を低減させることができるとともに、１バッチ終了時、輸送管５内に粉粒体を残留させた状態で待機するため、最終期には輸送圧力が上昇することもなく輸送効率を向上させることができる。
しかし、フルラインコンセプト輸送の場合では１バッチ終了時、輸送管５内に粉粒体を残留させた状態で待機させるために、例えば都市ゴミ焼却炉の飛灰輸送など吸湿性が高く物性変化を起こしやすい粉粒体においては１バッチ終了後に長時間輸送が再開されないときなどには潮解現象をおこし、粉粒体が輸送管５内に付着し、場合によっては輸送管５内面を腐食してしまうといった問題があった（特許文献１参照）。
特開平７−３０９４３６号公報 Also, in the case of full line concept transportation, transportation of the granular material is temporarily stopped when it is detected by the level meter or load cell (weight meter) that the granular material has disappeared in the transporter 6 and is necessary for the storage tank 2 When a sufficient amount of powder is collected, the gate valve 3 and the inlet valve 4 are opened, a predetermined amount of powder is sent to the transporter 6 again, and transportation is resumed. Consumption can be reduced, and at the end of one batch, since the standby state with the powder particles remaining in the transport pipe 5, the transport pressure is not increased in the final stage and the transport efficiency is improved. be able to.
However, in the case of full-line concept transportation, at the end of one batch, in order to wait with the powder particles remaining in the transportation pipe 5, for example, fly ash transportation in a municipal waste incinerator has high moisture absorption and changes in physical properties. In the case of a granular material that is prone to occur, a deliquescent phenomenon occurs when transportation is not resumed for a long time after the end of one batch. (See Patent Document 1).

本発明は、上記従来の気体輸送の制御方法の有する問題点に鑑み、フルラインコンセプト輸送の利点とコンベンショナルコンセプト輸送の利点とを併せもつ気体輸送の制御方法とその装置を提供することを目的とする。   An object of the present invention is to provide a gas transport control method and an apparatus therefor that combine the advantages of full-line concept transport and conventional concept transport in view of the problems of the conventional gas transport control method. To do.

上記目的を達成するため、本発明の気体輸送の制御方法は、貯留槽から送られてきた粉粒体を蓄えるトランスポータ内に一定量の粉粒体が溜まった後、トランスポータ内の内圧を一定圧力まで上昇せしめ、ブースタノズルからの圧縮空気によって輸送管内に粉粒体を残存させることなく粉粒体を輸送する気体輸送の制御方法において、トランスポータの粉粒体の有無を検知するレベル計が、粉粒体がなくなったことを検知するとともに、貯留槽内の粉粒体の量を計測するレベル計が、所定量の粉粒体の量を検知したときに、圧縮空気の供給を止め、輸送管内に粉粒体を残存させた状態で、貯留槽に蓄えられた粉粒体をトランスポータに送り込み、トランスポータ内に一定量の粉粒体が溜まった後、トランスポータ内の内圧を一定圧力まで上昇せしめ、ブースタノズルからの圧縮空気によって粉粒体の輸送を再開するようにしたことを特徴とする。   In order to achieve the above object, the gas transport control method according to the present invention is configured such that after a certain amount of particles accumulates in the transporter that stores the particles sent from the storage tank, the internal pressure in the transporter is increased. A level meter that detects the presence or absence of transporter powder in a gas transport control method that raises the pressure to a certain level and transports the powder without compressed powder from the booster nozzle. However, when the level meter that measures the amount of powder in the storage tank detects the amount of powder in the storage tank, it stops supplying compressed air. In the state where the granular material remains in the transport pipe, the granular material stored in the storage tank is sent to the transporter, and after a certain amount of granular material has accumulated in the transporter, the internal pressure in the transporter is reduced. Increase to constant pressure Tighten, characterized in that so as to resume the transport of granular material by means of compressed air from the booster nozzle.

また、前記制御方法を用いた本発明の気体輸送装置は、貯留槽から送られてきた粉粒体を一時的に蓄えるトランスポータと、該トランスポータに内圧をかけるトップエアノズルと、トランスポータのコーン部に配設したジェットノズルと、輸送管内の粉粒体を圧送するブースタノズルとからなる気体輸送装置において、貯留槽内の粉粒体の量を計測するレベル計と、トランスポータ内の粉粒体の量を計測するレベル計とを配設し、レベル計の値によって輸送管内に粉粒体を残存させたまま貯留槽から粉粒体をトランスポータ内に送るように制御する制御機構とを設けたことを特徴とする。   In addition, the gas transport device of the present invention using the control method includes a transporter that temporarily stores powder particles sent from a storage tank, a top air nozzle that applies internal pressure to the transporter, and a cone of the transporter. Level meter for measuring the amount of powder in the storage tank, and powder in the transporter in a gas transport device comprising a jet nozzle arranged in the section and a booster nozzle that pumps the powder in the transport pipe A level meter that measures the amount of the body, and a control mechanism that controls to send the granular material from the storage tank into the transporter with the granular material remaining in the transport pipe according to the value of the level meter It is provided.

本発明の気体輸送の制御方法とその装置によれば、トランスポータの粉粒体の有無を検知するレベル計が、粉粒体がなくなったことを検知するとともに、貯留槽内の粉粒体の量を計測するレベル計が、所定量（トランスポータの容量分の量）の粉粒体の量を検知したときに、圧縮空気の供給を止め、輸送管内に粉粒体を残存させた状態で、貯留槽に蓄えられた粉粒体をトランスポータに送り込み、トランスポータ内に一定量の粉粒体が溜まった後、トランスポータ内の内圧を一定圧力まで上昇せしめ、ブースタノズルからの圧縮空気によって粉粒体の輸送を再開するようにしたから、貯留槽に溜まる粉粒体の量が多くない場合にはコンベンショナルコンセプト輸送によってトランスポータ内の粉粒体を送りきる運転を行い、貯留槽に溜まる粉粒体の量が、トランスポータ内の粉粒体がなくなる時点、つまり輸送管内には粉粒体が残留している時点でトランスポータ内の容量分だけ溜まっているときにはフルラインコンセプト輸送に切り換えて粉粒体を輸送するから、コンベンショナルコンセプト輸送とフルラインコンセプト輸送との長所を併せもった気体輸送の制御方法とその装置を提供することができる。   According to the gas transport control method and apparatus of the present invention, the level meter for detecting the presence or absence of the transporter powder particles detects the absence of the powder particles, and the powder particles in the storage tank. When the level meter that measures the amount detects the amount of powder (amount corresponding to the capacity of the transporter), the supply of compressed air is stopped and the powder is left in the transport pipe. Then, after the granular material stored in the storage tank is sent to the transporter and a certain amount of granular material is accumulated in the transporter, the internal pressure in the transporter is increased to a constant pressure, and the compressed air from the booster nozzle Since the transport of powder and particles is resumed, if the amount of powder and particles collected in the storage tank is not large, the operation is carried out to send the powder and particles in the transporter by conventional concept transport, and the powder is collected in the storage tank. powder Switch to full line concept transport when the amount of body is no longer contained in the transporter, that is, when the amount of powder in the transport pipe remains at the transporter's capacity. Since particles are transported, it is possible to provide a method and apparatus for controlling gas transport that combines the advantages of conventional concept transport and full-line concept transport.

以下、本発明の気体輸送の制御方法とその装置の実施の形態を、図面に基づいて説明する。なお、従来装置と同様の構造については同一の符号、一連の符号を付し説明を省略する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a gas transport control method and apparatus according to the present invention will be described below with reference to the drawings. In addition, about the structure similar to a conventional apparatus, the same code | symbol and a series of code | symbol are attached | subjected, and description is abbreviate | omitted.

図１に、本発明の気体輸送装置の第１実施例を示す。
この気体輸送装置１は、従来例と同様に粉粒体を貯える貯留槽２と、該貯留槽２の下流側にゲートバルブ３及びインレットバルブ４をこの順に設け、ゲートバルブ３とインレットバルブ４とを開放し、貯留槽２内の粉粒体をトランスポータ６に一定量送り込み、ゲートバルブ３とインレットバルブ４とを閉鎖し、エアレシーバ７内の圧縮空気をブースタノズルＮＢ０を介して輸送管５内に送り、輸送管５の長さに応じて途中ブースタノズルＮＢ１、ＮＢ２・・・を配設することによって粉粒体を輸送先のサイロ（図示省略）に搬送するようにしている。
また、トランスポータ６内の圧力を上昇させておくための複数本のトップエアノズルＮＴを配設するとともに、トランスポータ６内に滞留する粉粒体に対してトランスポータコーン部６ａに付着しないようにジェットノズルＮＪ１、ＮＪ２・・・ＮＪｎを多数内壁に配設し、コーン部６ａの内壁に旋回流を作り、コーン部６ａでの粉体の流動性を高め、コーン部６ａに粉粒体が付着しないようにしている。 FIG. 1 shows a first embodiment of the gas transport device of the present invention.
As in the conventional example, this gas transport device 1 is provided with a storage tank 2 for storing powder particles, a gate valve 3 and an inlet valve 4 in this order on the downstream side of the storage tank 2, and a gate valve 3 and an inlet valve 4 Is opened, a certain amount of powder in the storage tank 2 is fed into the transporter 6, the gate valve 3 and the inlet valve 4 are closed, and the compressed air in the air receiver 7 is transported through the booster nozzle NB0 to the transport pipe 5 And the booster nozzles NB1, NB2,... Are arranged on the way according to the length of the transport pipe 5 so as to transport the granular material to a transport destination silo (not shown).
In addition, a plurality of top air nozzles NT for increasing the pressure in the transporter 6 are provided, and powder particles staying in the transporter 6 are not attached to the transporter cone portion 6a. A number of jet nozzles NJ1, NJ2,... NJn are arranged on the inner wall, creating a swirling flow on the inner wall of the cone portion 6a, increasing the fluidity of the powder at the cone portion 6a, and adhering the granular material to the cone portion 6a. I try not to.

そして、本発明の気体輸送装置１では、貯留槽２内の粉粒体の量を計測するレベル計ＬＶ１と、トランスポータ６内の粉粒体の残存量を計測するレベル計ＬＶ２とを配設し、レベル計ＬＶ１、ＬＶ２の値によって輸送管５内に粉粒体を残存させたまま貯留槽２から粉粒体をトランスポータ６内に送るように制御する制御機構８とを設けるようにしている。
レベル計ＬＶ１は、貯留槽２内の粉粒体量を計測するもので、トランスポータ６の容量分の粉粒体が貯留槽２に蓄えられたか否かのみを判定しそれを検知するレベル計の他、貯留槽２全体の重量を計測し、貯留槽２の重量を差し引くことによって貯留槽２内の粉粒体量を正確に計測する重量計を用いても構わない。
また、レベル計ＬＶ２は、トランスポータ６内に粉粒体が残存するか否かを判断することができる機能を有しておればよく、その設置場所はトランスポータ６適所の他、図例の如くトランスポータ６の出口近傍に備えてもよい。
制御機構８は、レギュレータＰＳ１〜３と電磁弁Ｓ１〜３とを制御する他、ゲートバルブ３とインレットバルブ４との開放の制御も行うようにすることが好ましい。 And in the gas transport apparatus 1 of this invention, the level meter LV1 which measures the quantity of the granular material in the storage tank 2, and the level meter LV2 which measures the residual quantity of the granular material in the transporter 6 are arrange | positioned. In addition, a control mechanism 8 is provided that controls to send the granular material from the storage tank 2 into the transporter 6 while the granular material remains in the transport pipe 5 according to the values of the level meters LV1 and LV2. Yes.
The level meter LV1 measures the amount of powder and granular material in the storage tank 2, and only determines whether or not the powder for the capacity of the transporter 6 has been stored in the storage tank 2 and detects it. In addition, the weight of the whole storage tank 2 may be measured, and the weight meter which measures the amount of the granular material in the storage tank 2 correctly by subtracting the weight of the storage tank 2 may be used.
Further, the level meter LV2 only needs to have a function capable of determining whether or not the powder particles remain in the transporter 6, and the installation location thereof is not limited to a suitable place of the transporter 6, but in the illustrated example. As described above, it may be provided near the outlet of the transporter 6.
The control mechanism 8 preferably controls the opening of the gate valve 3 and the inlet valve 4 in addition to controlling the regulators PS1 to PS3 and the electromagnetic valves S1 to S3.

しかして、粉粒体の輸送運転に際しては、通常はコンベンショナルコンセプト輸送を基本として運転制御を行うように制御機構８によって設定され、トランスポータ６内に粉粒体がなくなったときに、レベル計ＬＶ１によって貯留槽２内にトランスポータ６の容量分の粉粒体が溜まっていないと判断された場合には、輸送管５内に粉粒体が残存しないようにブースタノズルＮＢの圧縮空気によって粉粒体を送りきり、トランスポータ６内に粉粒体がなくなったときに、レベル計ＬＶ１によって貯留槽２内にトランスポータ６の容量分の粉粒体が溜まっていると判断された場合には、トップエアノズルＮＴ、ブースタノズルＮＢ、ジェットノズルＮＪを停止し一旦輸送を止め、輸送管５内に粉粒体を残存させたままゲートバルブ３とインレットバルブ４を開放し、再度トランスポータ６内に所定量の粉粒体を送り込む。
そして、トランスポータ６内に所定量の粉粒体を送り込んだ後、ゲートバルブ３とインレットバルブ４とを閉鎖し、トップエアノズルＮＴによってトランスポータ６内を昇圧し、ブースタノズルＮＢからの圧縮空気によって粉粒体の輸送を再開する所謂、フルラインコンセプト輸送となるように制御機構８によって輸送方法を切り換える。 Thus, when the granular material is transported and operated, the control mechanism 8 is usually set to control the operation based on the conventional concept transportation, and when the granular material disappears in the transporter 6, the level meter LV1 When it is determined that the amount of the granular material of the transporter 6 is not accumulated in the storage tank 2, the granular material is compressed by the compressed air of the booster nozzle NB so that the granular material does not remain in the transport pipe 5. When it is judged that the level meter LV1 has accumulated the granular material for the capacity of the transporter 6 in the storage tank 2 when the body is completely fed and the granular material is exhausted in the transporter 6, Stop the top air nozzle NT, booster nozzle NB, and jet nozzle NJ, stop transportation once, and leave the granules in the transport pipe 5 with the gate valve 3 and the inlet Opening the lube 4 feed the predetermined amount of granular body transporter 6 again.
Then, after feeding a predetermined amount of powder into the transporter 6, the gate valve 3 and the inlet valve 4 are closed, the pressure inside the transporter 6 is increased by the top air nozzle NT, and the compressed air from the booster nozzle NB is used. The transport mechanism is switched by the control mechanism 8 so that the so-called full-line concept transport is resumed.

なお、レベル計ＬＶ１によって測定する貯留槽２内の粉粒体の量がトランスポータ６の容量の１００％に満たない場合であっても、一定量（例えばトランスポータ６の容量の８０％）となっているときは、コンベンショナルコンセプト輸送からフルラインコンセプト輸送に切り換えて運転するように制御することもできる。   Even when the amount of the granular material in the storage tank 2 measured by the level meter LV1 is less than 100% of the capacity of the transporter 6, it is a constant amount (for example, 80% of the capacity of the transporter 6). When it is, it can be controlled to switch from conventional concept transportation to full line concept transportation.

以上、本発明の気体輸送装置について、実施例に基づいて説明したが、本発明は上記実施例に記載した構成に限定されるものではなく、その趣旨を逸脱しない範囲において適宜その構成を変更することができるものである。   As mentioned above, although the gas transport apparatus of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, The structure is suitably changed in the range which does not deviate from the meaning. It is something that can be done.

本発明の気体輸送装置は、トランスポータ内に粉粒体がなくなったときの貯留槽の粉粒体量に応じてコンベンショナルコンセプト輸送とフルラインコンセプト輸送とを切り換えて運転制御するという特性を有していることから、新規設備に用いることができる他、例えば、既設設備においてもレベル計を配設し、制御機構を改造することで適用することができる。   The gas transportation device of the present invention has a characteristic that operation control is performed by switching between conventional concept transportation and full-line concept transportation according to the amount of powder in the storage tank when there is no powder in the transporter. Therefore, in addition to being able to be used for new equipment, for example, it can be applied to existing equipment by arranging a level meter and modifying the control mechanism.
