Description
本発明は、揮発性成分含有物質から揮発性成分を除去する、揮発性成分含有物質の処理システムに関する。 The present invention relates to a processing system for a volatile component-containing material that removes a volatile component from the volatile component-containing material.
セメント製造では、水銀などの揮発性成分を微量に含有する天然および廃棄物系の原燃料を使用しているため、セメントの焼成工程で使用されるセメントキルンから排出されるセメントキルン排ガスには揮発性成分が含まれている。このような揮発性成分による環境負荷を低減するためには、セメントキルン排ガスから揮発性成分を除去して回収する必要がある。しかし、セメントキルン排ガスに低濃度で含まれている揮発性成分を、大量に発生するセメントキルン排ガスから除去することは難しい。このため、従来から、セメントキルン排ガスから揮発性成分を除去する様々な方法が提案されてきた（たとえば、特許文献１参照）。 Cement production uses natural and waste-based raw fuels that contain trace amounts of volatile components such as mercury, so it is volatile to the cement kiln exhaust gas emitted from the cement kiln used in the cement firing process. Contains sexual components. In order to reduce the environmental load caused by such volatile components, it is necessary to remove and recover the volatile components from the cement kiln exhaust gas. However, it is difficult to remove volatile components contained in cement kiln exhaust gas at a low concentration from cement kiln exhaust gas generated in large quantities. For this reason, conventionally, various methods for removing volatile components from cement kiln exhaust gas have been proposed (see, for example, Patent Document 1).
特許文献１に記載の揮発性物質の除去方法では、内部にスクリューフィーダを備えた加熱炉を使用して集塵ダストの揮発性物質を除去している。集塵ダストはスクリューフィーダにより加熱炉の中を移動する。移動している間に集塵ダストは加熱され、集塵ダストから揮発性物質が揮発し、集塵ダストから揮発性物質が除去される。そして、集塵ダストはさらに移動して、加熱炉の排出口から排出され、粉砕装置に移送される。 In the method for removing a volatile substance described in Patent Document 1, a volatile substance in dust collection dust is removed using a heating furnace provided with a screw feeder inside. Dust collection dust moves through the heating furnace using a screw feeder. While moving, the dust collection dust is heated, volatile substances are volatilized from the dust collection dust, and volatile substances are removed from the dust collection dust. The dust collecting dust further moves, is discharged from the discharge port of the heating furnace, and is transferred to the pulverizing apparatus.
集塵ダストにおける揮発性物質の揮発率を向上させるためには、揮発性物質の揮発を促進させるために加熱炉の温度を上昇させればよい。しかし、加熱炉の熱源としてニクロム線およびカンタル線などの発熱体を用いた加熱炉の場合、加熱炉の温度を上昇させると、加熱炉に供給する電力量が増加し、加熱炉の熱源として石油バーナーおよびガスバーナーなどを用いた加熱炉の場合、燃料消費量が増加し、集塵ダストから揮発性物質を除去するためのコストが上昇する。そこで、本発明は、加熱炉の温度を上昇させる以外の方法で揮発性成分の揮発率を向上させることができる揮発性成分含有物質の処理システムを提供することを目的とする。 In order to improve the volatility rate of the volatile substance in the dust collection dust, the temperature of the heating furnace may be increased in order to promote the volatilization of the volatile substance. However, in the case of a heating furnace using a heating element such as a nichrome wire and a Kanthal wire as a heat source for the heating furnace, if the temperature of the heating furnace is increased, the amount of power supplied to the heating furnace increases, In the case of a heating furnace using a burner and a gas burner, the amount of fuel consumption increases and the cost for removing volatile substances from dust collection dust increases. Then, an object of this invention is to provide the processing system of the volatile component containing substance which can improve the volatility rate of a volatile component by methods other than raising the temperature of a heating furnace.
本発明者らは、鋭意研究を行った結果、加熱装置における揮発性成分含有物質の輸送方向を水平面に対して傾斜させることにより、揮発性成分の揮発率を変えられることを見出し、本発明を完成させた。すなわち、本発明は以下のとおりである。

（加熱装置）

図２を参照して加熱装置１０を詳細に説明する。図２は、本発明の一実施形態における揮発性成分含有物質の処理システムの加熱装置および傾斜角度調整装置を説明するための図である。図２には、加熱装置１０の一例の内部構造が示されている。図２の符号Ｄは揮発性成分含有物質を示し、符号Ｖは揮発性成分を示す。なお、図２に示す加熱装置１０はあくまでも一例であり、本発明の揮発性成分含有物質の処理システムの加熱装置は、揮発性成分含有物質を輸送しながら加熱することができれば、図２に示す加熱装置１０に限定されない。 The heating apparatus 10 will be described in detail with reference to FIG. FIG. 2 is a view for explaining a heating device and an inclination angle adjusting device of a volatile component-containing substance processing system according to an embodiment of the present invention. FIG. 2 shows an internal structure of an example of the heating device 10. The code | symbol D of FIG. 2 shows a volatile component containing substance, and the code | symbol V shows a volatile component. Note that the heating device 10 shown in FIG. 2 is merely an example, and the heating device of the processing system for a volatile component-containing material of the present invention is shown in FIG. 2 if it can be heated while transporting the volatile component-containing material. It is not limited to the heating device 10.
図２に示す加熱装置１０は、揮発性成分含有物質導入部１１、本体部１２、スクリューコンベア１３、揮発性成分含有物質排出部１４、揮発性成分排出部１５および加熱ヒーター１６を備える。揮発性成分含有物質導入部１１は、本体部１２の一方の端１７側の上部に設けられ、集塵装置Ｋなどから供給された揮発性成分含有物質を、本体部１２の中に導入するための導入口である。 A heating apparatus 10 shown in FIG. 2 includes a volatile component-containing substance introduction unit 11, a main body unit 12, a screw conveyor 13, a volatile component-containing substance discharge unit 14, a volatile component discharge unit 15, and a heater 16. The volatile component-containing substance introducing unit 11 is provided at the upper part on the one end 17 side of the main body 12 and introduces the volatile component-containing substance supplied from the dust collector K or the like into the main body 12. This is the introduction point.
本体部１２は、円筒の形状を有している。揮発性成分含有物質は本体部１２の中で輸送されるとともに加熱される。本体部１２の内部には、本体部１２の長さ方向に沿って、スクリューコンベア１３が設けられている。スクリューコンベア１３は、ねじ羽根を取り付けたシャフトの回転によって、本体部１２の一方の端１７側から他方の端１８側に、揮発性成分含有物質を、本体部１２の長さ方向に沿って輸送する。本体部１２の長手方向の真ん中付近に、本体部１２の外周に沿って加熱ヒーター１６が配置されている。加熱ヒーター１６は、本体部１２の外部から本体部１２の内部にある揮発性成分含有物質を加熱する。 The main body 12 has a cylindrical shape. The volatile component-containing material is transported and heated in the main body 12. Inside the main body 12, a screw conveyor 13 is provided along the length direction of the main body 12. The screw conveyor 13 transports the volatile component-containing substance along the length direction of the main body 12 from the one end 17 side to the other end 18 side of the main body 12 by the rotation of the shaft to which the screw blades are attached. To do. A heater 16 is disposed along the outer periphery of the main body 12 near the middle of the main body 12 in the longitudinal direction. The heater 16 heats the volatile component-containing material inside the main body 12 from the outside of the main body 12.
揮発性成分含有物質排出部１４は、本体部１２の他方の端１８側の下部に設けられ、揮発性成分が揮発した物質を本体部１２から排出するための排出口である。揮発性成分排出部１５は、本体部１２の他方の端１８側の上部に設けられ、揮発性成分含有物質から揮発した揮発性成分を本体部１２から排出するための排出口である。揮発性成分排出部１５は不図示の吸引ファンと接続しており、吸引により揮発性成分含有物質から揮発した揮発性成分は揮発性成分排出部１５に導かれる。 The volatile component-containing material discharge unit 14 is a discharge port that is provided at a lower portion on the other end 18 side of the main body 12 and discharges the material from which the volatile component has volatilized from the main body 12. The volatile component discharge unit 15 is provided at an upper portion on the other end 18 side of the main body 12 and is a discharge port for discharging a volatile component volatilized from the volatile component-containing substance from the main body 12. The volatile component discharge unit 15 is connected to a suction fan (not shown), and the volatile component volatilized from the volatile component-containing material by suction is led to the volatile component discharge unit 15.
揮発性成分含有物質導入部１１から本体部１２に導入された揮発性成分含有物質は、スクリューコンベア１３により、本体部１２の一方の端１７側から他方の端１８側へ、徐々に移動する。揮発性成分含有物質が、加熱ヒーター１６が配置されている領域に移動すると、加熱ヒーター１６が発生する熱により、揮発性成分含有物質中の揮発性成分は揮発する。加熱ヒーター１６により揮発性成分が揮発した揮発性成分含有物質は、揮発性成分含有物質排出部１４に移動し、本体部１２（加熱装置１０）から排出される。また、揮発性成分含有物質から揮発した揮発性成分は、揮発性成分排出部１５を通過して本体部１２（加熱装置１０）から排出される。 The volatile component-containing substance introduced from the volatile component-containing substance introduction part 11 into the main body part 12 is gradually moved from one end 17 side of the main body part 12 to the other end 18 side by the screw conveyor 13. When the volatile component-containing material moves to the area where the heater 16 is disposed, the volatile component in the volatile component-containing material is volatilized by the heat generated by the heater 16. The volatile component-containing material whose volatile component has been volatilized by the heater 16 moves to the volatile component-containing material discharge portion 14 and is discharged from the main body portion 12 (heating device 10). Moreover, the volatile component volatilized from the volatile component-containing material passes through the volatile component discharge unit 15 and is discharged from the main body 12 (heating device 10).
加熱装置１０により揮発性成分含有物質を加熱するときの本体部１２の内部温度は、たとえば揮発性成分含有物質がセメントキルンから排出される集塵ダストであり、揮発性成分が水銀である場合、好ましくは３００〜６００℃であり、より好ましくは３００〜４５０℃である。本体部１２の内部温度を３００〜６００℃にすることにより、揮発性成分含有物質から揮発性成分を効率的に揮発させることができる。 The internal temperature of the main body 12 when the volatile component-containing substance is heated by the heating device 10 is, for example, dust collection dust from which the volatile component-containing substance is discharged from the cement kiln, and the volatile component is mercury. Preferably it is 300-600 degreeC, More preferably, it is 300-450 degreeC. By setting the internal temperature of the main body 12 to 300 to 600 ° C., the volatile component can be efficiently volatilized from the volatile component-containing substance.
図１に示すように、加熱装置１０から排出された揮発性成分は揮発性成分回収装置３０に移送される。加熱装置１０から排出された揮発性成分含有物質は、たとえばセメント原料Ｌとして使用される。 As shown in FIG. 1, the volatile component discharged from the heating device 10 is transferred to the volatile component recovery device 30. The volatile component-containing material discharged from the heating device 10 is used as the cement raw material L, for example.
（傾斜角度調整装置）
傾斜角度調整装置２０は、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、輸送方向が下方に向かう方向に調整することができる。傾斜角度調整装置２０は、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、輸送方向が下方に向かう方向に調整することができればとくに限定されない。ここで、輸送方向とは、揮発性成分含有物質が輸送される方向である。たとえば、コンベアがスクリューコンベアおよびパドル式コンベアである場合、スクリューコンベアのシャフトが延びている方向であり、コンベアが振動コンベアである場合、振動するトラフが延びている方向である。また、輸送方向が下方に向かう方向とは、輸送方向が下るようになる方向である。
(Inclination angle adjustment device)
The inclination angle adjusting device 20 can adjust the inclination angle between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane in the direction in which the transport direction is directed downward. The tilt angle adjusting device 20 is not particularly limited as long as the tilt angle between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane can be adjusted in a direction in which the transport direction is directed downward. Here, the transport direction is the direction in which the volatile component-containing material is transported. For example, when the conveyor is a screw conveyor and a paddle type conveyor, it is the direction in which the shaft of the screw conveyor extends, and when the conveyor is a vibrating conveyor, it is the direction in which the vibrating trough extends. The direction in which the transport direction is directed downward is a direction in which the transport direction is lowered.
傾斜角度調整装置２０は、加熱装置１０を傾斜させることにより、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、輸送方向が下方に向かう方向に調整してもよい。また、傾斜角度調整装置２０は、加熱装置１０を傾斜させずに、コンベアを傾斜させることにより、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、輸送方向が下方に向かう方向に調整してもよい。さらに、傾斜角度調整装置２０は、加熱装置１０を傾斜させ、さらに加熱装置１０におけるコンベアの相対的な
傾きを変えることにより、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、輸送方向が下方に向かう方向に調整してもよい。
The tilt angle adjusting device 20 may adjust the tilt angle between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane in a direction in which the transport direction is directed downward by tilting the heating device 10. In addition, the tilt angle adjusting device 20 tilts the conveyor without tilting the heating device 10, so that the tilt angle between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane is reduced downward in the transport direction. You may adjust to the direction which goes. Further, the tilt angle adjusting device 20 tilts the heating device 10 and further changes the relative tilt of the conveyor in the heating device 10 to thereby tilt the tilt angle between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane. May be adjusted in a direction in which the transport direction is directed downward.
加熱装置を傾斜させる方法には、たとえば油圧シリンダの伸長および油圧ジャッキの伸長などにより、加熱装置１０の一方の端の高さを、他方の端の高さに対して変えることにより、または、ワイヤーを利用してウインチで巻き上げることにより加熱装置１０の一方の端側を吊り上げて、加熱装置１０の一方の端の高さを、他方の端の高さに対して変えることにより、揮発性成分含有物質の輸送方向の傾斜角度を、輸送方向が下方に向かう方向に調整する方法などがある。また、加熱装置１０を傾斜させずに、コンベアを傾斜させる方法には、たとえば、コンベアの一方の端を上下方向に可動にする方法などが挙げられる。 The method of inclining the heating device includes changing the height of one end of the heating device 10 relative to the height of the other end, for example, by extending a hydraulic cylinder and a hydraulic jack, One end side of the heating device 10 is lifted up by winding it with a winch using the, and the height of one end of the heating device 10 is changed with respect to the height of the other end, thereby containing a volatile component There is a method of adjusting the inclination angle of the transport direction of the substance so that the transport direction is directed downward. Further, examples of the method of tilting the conveyor without tilting the heating device 10 include a method of moving one end of the conveyor vertically.
傾斜角度調整装置２０が、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、輸送方向が下方に向かう方向に調整することにより、揮発性成分含有物質における揮発性成分の揮発率を向上させることができる。以下の原理は本発明を限定するものではないが、この揮発性成分の揮発率の向上は、輸送方向が下方に向かう方向に傾いているので、コンベアにより輸送中の揮発性成分含有物質になだれ現象が生じ、これにより揮発性成分含有物質が攪拌され、揮発性成分の揮発性成分含有物質からの揮発が促進されるためであると推測される。このなだれ現象が起こる上記傾斜角度は、コンベアの種類および加熱装置１０に投入される揮発性成分含有物質の投入量、含水率、粒度分布および安息角により変わると考えられる。したがって、コンベアの種類および加熱装置１０に投入される揮発性成分含有物質の投入量、含水率、粒度分布および安息角によって、上記傾斜角度を決定するようにしてもよい。 The inclination angle adjusting device 20 adjusts the inclination angle between the transport direction of the volatile component-containing material by the conveyor and the horizontal plane in the direction in which the transport direction is directed downward, so that the volatile component in the volatile component-containing material is reduced. Volatilization rate can be improved. The following principle does not limit the present invention, but the improvement in the volatility rate of this volatile component is avalanche of the volatile component-containing material being transported by the conveyor because the transport direction is inclined downward. It is presumed that this occurs because a phenomenon occurs, whereby the volatile component-containing material is stirred, and volatilization of the volatile component from the volatile component-containing material is promoted. The inclination angle at which this avalanche phenomenon occurs is considered to vary depending on the type of conveyor and the amount of volatile component-containing material charged into the heating device 10, the moisture content, the particle size distribution, and the angle of repose. Therefore, the inclination angle may be determined according to the type of conveyor and the amount of volatile component-containing material charged into the heating device 10, the moisture content, the particle size distribution, and the angle of repose.
図２を参照して傾斜角度調整装置２０を詳細に説明する。図２は、本発明の一実施形態における揮発性成分含有物質の処理システムの加熱装置および傾斜角度調整装置を説明するための図である。なお、図２に示す傾斜角度調整装置２０はあくまでも一例であり、本発明の揮発性成分含有物質の処理システムにおける傾斜角度調整装置は、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、輸送方向が下方に向かう方向に調整することができれば、図２に示す傾斜角度調整装置２０に限定されない。 The tilt angle adjusting device 20 will be described in detail with reference to FIG. FIG. 2 is a view for explaining a heating device and an inclination angle adjusting device of a volatile component-containing substance processing system according to an embodiment of the present invention. The tilt angle adjusting device 20 shown in FIG. 2 is merely an example, and the tilt angle adjusting device in the volatile component-containing substance processing system of the present invention is between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane. The inclination angle adjusting device 20 shown in FIG. 2 is not limited as long as the inclination angle can be adjusted in a direction in which the transport direction is directed downward.
傾斜角度調整装置２０は、加熱装置１０の本体部１２の下に設けられ、油圧シリンダ２１の伸長により、加熱装置１０の一方の端１７の高さを、他方の端１８の高さよりも高くなるように変えることにより、加熱装置１０の傾斜角度を、輸送方向が下方に向かう方向に調整することができる。すなわち、傾斜角度調整装置２０は、加熱装置１０を傾斜させることにより、スクリューコンベア１３による揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、輸送方向が下方に向かう方向に調整することができる。 The inclination angle adjusting device 20 is provided below the main body portion 12 of the heating device 10, and the height of one end 17 of the heating device 10 becomes higher than the height of the other end 18 due to the extension of the hydraulic cylinder 21. By changing in this way, the inclination angle of the heating device 10 can be adjusted in the direction in which the transport direction is directed downward. That is, the inclination angle adjusting device 20 adjusts the inclination angle between the transport direction of the volatile component-containing substance by the screw conveyor 13 and the horizontal plane in a direction in which the transport direction is directed downward by inclining the heating device 10. be able to.
傾斜角度調整装置２０による加熱装置１０の傾斜によって、スクリューコンベア１３により輸送中の揮発性成分含有物質になだれ現象が生じる。このなだれ現象により揮発性成分含有物質は撹拌され、揮発性成分含有物質からの揮発性成分の揮発が促進され、揮発性成分含有物質の揮発性成分の揮発率が向上すると推測できる。しかし、傾斜角度調整装置２０による加熱装置１０の傾斜が大きすぎると、揮発性成分含有物質の移動速度が非常に速くなり、揮発性成分含有物質は、揮発性成分が十分揮発されないうちに、揮発性成分含有物質排出部１４に達してしまい、本体部１２から排出される。このため、傾斜角度調整装置２０による加熱装置１０の傾斜が大きすぎると、揮発性成分含有物質の揮発性成分の揮発率が、かえって減少すると予想される。 Due to the inclination of the heating device 10 by the inclination angle adjusting device 20, an avalanche phenomenon occurs in the volatile component-containing material being transported by the screw conveyor 13. It can be assumed that the avalanche phenomenon stirs the volatile component-containing material, promotes volatilization of the volatile component from the volatile component-containing material, and improves the volatility rate of the volatile component of the volatile component-containing material. However, if the inclination of the heating device 10 by the inclination angle adjusting device 20 is too large, the moving speed of the volatile component-containing material becomes very fast, and the volatile component-containing material volatilizes before the volatile component is sufficiently volatilized. It reaches the sex component-containing substance discharge section 14 and is discharged from the main body section 12. For this reason, when the inclination of the heating device 10 by the inclination angle adjusting device 20 is too large, it is expected that the volatility rate of the volatile component of the volatile component-containing substance is reduced.
コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度の好ましい傾斜角度は、たとえば以下の方法で設定することができる。傾斜角度調整装置２０を使用して揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、０°から輸送方向が下方に向かう方向に徐々に変えていき、それぞれの傾斜角度において加熱装置１０により処理された揮発性成分含有物質中の揮発性成分の含有率を測定する。そして、揮発性成分の含有率がもっとも低くなったときの傾斜角度を好ましい傾斜角度として設定する。そして、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度がこの好ましい傾斜角度なるように傾斜角度を設定して、揮発性成分含有物質の揮発性成分の除去処理を開始する。また、後述の揮発性成分揮発率または揮発性成分除去量がもっとも高くなったときの傾斜角度を好ましい傾斜角度として設定して、揮発性成分含有物質の揮発性成分の除去処理を開始してもよい。なお、この場合は、好ましい傾斜角度を設定後、揮発性成分の除去処理をしているとき、処理システム１は、後述の揮発性成分分析装置、後述の揮発性成分含有物質供給量測定装置および後述の揮発性成分含有物質排出量測定装置を含まなくてもよい。 The preferable inclination angle of the inclination angle between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane can be set, for example, by the following method. The inclination angle adjusting device 20 is used to gradually change the inclination angle between the transport direction of the volatile component-containing substance and the horizontal plane from 0 ° to the downward direction of the transport direction, and heating at each inclination angle. The content rate of the volatile component in the volatile component-containing material processed by the apparatus 10 is measured. And the inclination angle when the content rate of a volatile component becomes the lowest is set as a preferable inclination angle. Then, the inclination angle is set so that the inclination angle between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane becomes the preferable inclination angle, and the removal processing of the volatile component of the volatile component-containing substance is started. . In addition, even when the volatile component volatility described later or the amount of volatile component removal becomes the highest, the inclination angle is set as a preferable inclination angle, and the volatile component removal treatment of the volatile component-containing substance is started. Good. In this case, when a volatile component removal process is performed after setting a preferable inclination angle, the processing system 1 includes a volatile component analyzer described later, a volatile component-containing substance supply measuring device described later, and It is not necessary to include a volatile component-containing substance discharge measuring device described later.
（揮発性成分回収装置）
揮発性成分回収装置３０は、揮発性成分含有物質から揮発した揮発性成分を回収する。揮発性成分回収装置３０には、たとえば、セメントの製造工程で、揮発性成分回収装置として通常用いられるものなどが使用される。揮発性成分回収装置３０は、たとえば、活性炭などの吸着剤に揮発性成分を吸着させて揮発性成分を回収する。また、揮発性成分回収装置３０は、揮発性成分を含有する加熱装置１０の排気を該揮発性成分の飽和温度以下に冷却し、凝縮して回収してもよい。
(Volatile component recovery equipment)
The volatile component recovery device 30 recovers a volatile component that has volatilized from the volatile component-containing material. The volatile component recovery device 30 is, for example, one that is normally used as a volatile component recovery device in a cement manufacturing process. The volatile component recovery device 30 recovers the volatile component by adsorbing the volatile component to an adsorbent such as activated carbon, for example. Further, the volatile component recovery device 30 may cool the exhaust of the heating device 10 containing the volatile component to a temperature equal to or lower than the saturation temperature of the volatile component, and condense and recover it.
（揮発性成分分析装置）
揮発性成分分析装置４０は、加熱装置１０により加熱される前の揮発性成分含有物質中の揮発性成分の濃度および加熱装置１０により加熱された後の揮発性成分含有物質中の揮発性成分の濃度を測定する。揮発性成分分析装置４０は、物質中の揮発性成分の濃度を測定できるものであれば、とくに限定されない。たとえば、揮発性成分分析装置４０は、原子吸光法で揮発性成分含有物質中の揮発性成分の濃度を測定してもよい。
(Volatile component analyzer)
The volatile component analyzer 40 is configured to measure the concentration of the volatile component in the volatile component-containing material before being heated by the heating device 10 and the concentration of the volatile component in the volatile component-containing material after being heated by the heating device 10. Measure the concentration. The volatile component analyzer 40 is not particularly limited as long as it can measure the concentration of the volatile component in the substance. For example, the volatile component analyzer 40 may measure the concentration of the volatile component in the volatile component-containing substance by atomic absorption method.
揮発性成分分析装置４０により測定された、加熱装置１０により加熱される前の揮発性成分含有物質中の揮発性成分の濃度と加熱装置１０により加熱された後の揮発性成分含有物質中の揮発性成分の濃度とから算出した揮発性成分揮発率に基づいて、傾斜角度調整装置２０は、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を調整するようにしてもよい。揮発性成分揮発率は、加熱装置１０により加熱される前の揮発性成分含有物質中の揮発性成分の濃度をＡ（ｍｇ／ｋｇ）とし、加熱装置１０により加熱された後の揮発性成分含有物質中の揮発性成分の濃度をＢ（ｍｇ／ｋｇ）とした場合、（Ａ−Ｂ）／Ａ×１００の式で算出される。これにより、加熱装置１０への揮発性成分含有物質の投入量、揮発性成分含有物質の安息角ならびに揮発性成分含有物質の濃度が変化しても、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、揮発性成分揮発率が目標値以上になるように傾斜角度を調整することができる。 The concentration of the volatile component in the volatile component-containing material before being heated by the heating device 10 measured by the volatile component analyzer 40 and the volatilization in the volatile component-containing material after being heated by the heating device 10 Based on the volatile component volatilization rate calculated from the concentration of the volatile component, the tilt angle adjusting device 20 may adjust the tilt angle between the transport direction of the volatile component-containing substance by the conveyor and the horizontal plane. . The volatile component volatility rate is A (mg / kg) as the concentration of the volatile component in the volatile component-containing material before being heated by the heating device 10, and contains the volatile component after being heated by the heating device 10. When the concentration of the volatile component in the substance is B (mg / kg), it is calculated by the formula of (A−B) / A × 100. Thereby, even if the input amount of the volatile component-containing material to the heating device 10, the angle of repose of the volatile component-containing material, and the concentration of the volatile component-containing material change, the transport direction of the volatile component-containing material by the conveyor The inclination angle with respect to the horizontal plane can be adjusted such that the volatile component volatility is equal to or higher than the target value.
傾斜角度調整装置２０は、揮発性成分分析装置４０により測定された、加熱装置１０により加熱された後の揮発性成分含有物質中の揮発性成分の濃度と加熱装置１０により加熱される前の揮発性成分含有物質中の揮発性成分の濃度との間の濃度差に、加熱装置１０に供給される揮発性成分含有物質の単位時間当たりの供給量または加熱装置１０から排出される揮発性成分含有物質の単位時間当たりの排出量をかけ算して算出した揮発性成分除去量に基づいて、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を調整するようにしてもよい。これにより、加熱装置１０への揮発性成分含有物質の投入量、揮発性成分含有物質の含水率、粒度分布および安息角ならびに揮発性成分含有物質の濃度が変化しても、コンベアによる揮発性成分含有物質の輸送方向と水平面との間の傾斜角度を、揮発性成分含有物質における揮発性成分除去量が目標値以上になるように傾斜角度を調整することができる。 The inclination angle adjusting device 20 measures the concentration of the volatile component in the volatile component-containing material after being heated by the heating device 10 and the volatilization before being heated by the heating device 10 as measured by the volatile component analyzing device 40. The difference in concentration between the volatile component in the volatile component-containing substance and the supply amount per unit time of the volatile component-containing substance supplied to the heating device 10 or the volatile component content discharged from the heating device 10 The inclination angle between the transport direction of the volatile component-containing material by the conveyor and the horizontal plane may be adjusted based on the volatile component removal amount calculated by multiplying the discharge amount of the substance per unit time. Thereby, even if the amount of the volatile component-containing material input to the heating device 10, the moisture content of the volatile component-containing material, the particle size distribution and the angle of repose, and the concentration of the volatile component-containing material change, the volatile component by the conveyor The tilt angle between the transport direction of the contained material and the horizontal plane can be adjusted so that the volatile component removal amount in the volatile component-containing material is equal to or greater than the target value.
加熱装置１０に供給される揮発性成分含有物質の単位時間当たりの供給量は、たとえば、加熱装置１０の上流にコンベヤスケールを設けることにより測定できる。また、加熱装置１０から排出される揮発性成分含有物質の単位時間当たりの排出量も同様に、たとえば、加熱装置１０の下流側にコンベヤスケールを設けることにより測定できる。 The supply amount per unit time of the volatile component-containing substance supplied to the heating device 10 can be measured, for example, by providing a conveyor scale upstream of the heating device 10. Similarly, the discharge amount per unit time of the volatile component-containing material discharged from the heating device 10 can be measured by, for example, providing a conveyor scale on the downstream side of the heating device 10.

Using the dust-collecting dust containing mercury removed from the exhaust gas from the cement kiln by the dust collector, the treatment system for the volatile component-containing material shown in FIG. 1 and the heating device and the tilt angle adjusting device shown in FIG. 2 are used. Then, the dust collection dust was processed. The amount of dust collected in the heating device was 14 kg / hour. The set temperature of the heating device was 420 ° C. or 450 ° C. By changing the length of the hydraulic cylinder of the tilt angle adjusting device, the tilt angle between the transport direction of dust collection dust and the horizontal plane was adjusted to 0 °, 5 °, 10 ° and 15 °. Using a mercury analyzer (manufactured by Nippon Instruments Co., Ltd., model number: MA-2000), before heating by the heating device at each set temperature of each heating device and each inclination angle in the transport direction of the volatile component-containing material. The mercury concentration (A) (mg / kg) of the dust collection dust and the mercury concentration (B) (mg / kg) of the dust collection dust after being heated by the heating device were measured. And mercury volatility was computed by the following formula.
Mercury volatility (%) = (A−B) / A × 100
これらの結果を以下の表１および表２に示す。
集塵ダストの輸送方向と水平面との間の傾斜角度を調整することによって、集塵ダストの水銀揮発率を変えられた。また、傾斜角度が５°および１０°の場合、本体部を傾斜させない場合に比べて、水銀揮発率が高くなった。さらに、傾斜角度が１０°の場合に、集塵ダストの水銀除去がもっとも高くなった。 By adjusting the angle of inclination between the transport direction of the dust collection dust and the horizontal plane, the mercury volatilization rate of the dust collection dust can be changed. Further, when the tilt angles were 5 ° and 10 °, the mercury volatilization rate was higher than when the main body was not tilted. Furthermore, when the inclination angle was 10 °, the mercury removal from the dust collection dust was the highest.
