Description

本発明は、軸線回りに回転される炉本体を有するロータリーキルン炉において前記炉本体の内部温度を測定するためのロータリーキルン炉用温度測定装置及びこの温度測定装置を備えたロータリーキルン炉に関する。   The present invention relates to a rotary kiln furnace temperature measuring device for measuring the internal temperature of the furnace body in a rotary kiln furnace having a furnace body rotated about an axis, and a rotary kiln furnace provided with the temperature measuring device.

前述のロータリーキルン炉は、産業廃棄物等を高温処理する有効な装置として広く利用されている。例えば自動車のシュレッダーダストや廃家電品をはじめとする金属を含有する産業廃棄物を高温処理する場合には、炉本体の内部に投入された被処理物のうち、例えばウレタンなどの可燃物をガス化し、金属を含む不燃物を溶融して溶融スラグとする。ここで形成された溶融スラグから、鉄（Ｆｅ）をはじめとして銅（Ｃｕ）、金（Ａｕ）、銀（Ａｇ）などの有用または高価な金属を回収する。一方、炉本体の内部で生成されたガスは、下流側のガス処理装置によって無害化されて大気中に排出される。   The above-described rotary kiln furnace is widely used as an effective device for treating industrial waste and the like at a high temperature. For example, when industrial waste containing metals such as automobile shredder dust and waste home appliances is treated at high temperature, combustibles such as urethane are gasified from the materials to be treated that are put into the furnace body. And incombustible material containing metal is melted to form molten slag. From the molten slag formed here, useful or expensive metals such as iron (Fe), copper (Cu), gold (Au), and silver (Ag) are recovered. On the other hand, the gas generated inside the furnace body is rendered harmless by the downstream gas processing device and discharged into the atmosphere.

このようなロータリーキルン炉においては、炉本体の内部温度を測定して前記内部温度を安定させるように操業が行われている。炉本体の内部温度の測定方法として、例えば特許文献１、２には、放射温度計を利用するものが提案されている。しかしながら、放射温度計では、炉本体内部がダスト等により曇った場合に正確な温度測定ができなくなってしまう。   In such a rotary kiln furnace, an operation is performed so as to stabilize the internal temperature by measuring the internal temperature of the furnace body. As a method for measuring the internal temperature of the furnace body, for example, Patent Documents 1 and 2 propose using a radiation thermometer. However, with the radiation thermometer, accurate temperature measurement cannot be performed when the inside of the furnace body is clouded with dust or the like.

そこで、熱電対や測温抵抗体等を炉本体内部に配設して炉本体の内部温度を直接測定する方法が提案されている。ここで、炉本体が軸線を中心として回転されるのにともなって熱電対や測温抵抗体等も軸線中心として移動することになるため、炉本体に測定データを送信するための送信機を配設し、測定データを受信機へと送信するように構成されたものが提案されている。この送信機を動作させるために必要な電力の供給方法として、炉本体の外周面にトロリー線を巻回して給電装置のスリップリングから供給する方法、炉本体にコイルを巻いて２次コイルを接近させることで発生する誘導電流を使用する方法（例えば、特許文献３参照）、送信機にバッテリーを組み込む方法が提案されている。
特開平０８−２９２６０号公報 特開平１０−３３２１２４号公報 特開２００４−１１９９０号公報 Therefore, a method has been proposed in which a thermocouple, a resistance temperature detector, or the like is disposed inside the furnace body and the internal temperature of the furnace body is directly measured. Here, as the furnace body is rotated about the axis, the thermocouple, resistance temperature detector, and the like also move about the axis, so a transmitter for transmitting measurement data to the furnace body is arranged. And configured to transmit measurement data to a receiver. As a method of supplying power necessary to operate this transmitter, a method of supplying a trolley wire around the outer peripheral surface of the furnace body and supplying it from a slip ring of the power feeding device, a coil is wound around the furnace body and a secondary coil is approached There have been proposed a method of using an induced current generated by the operation (see, for example, Patent Document 3) and a method of incorporating a battery in a transmitter.
Japanese Patent Application Laid-Open No. 08-29260 Japanese Patent Laid-Open No. 10-332124 JP 2004-111990 A

ところで、炉本体の外周面にトロリー線を巻回して給電装置のスリップリングから電力を供給する方法や炉本体にコイルを巻いて２次コイルを接近させることで発生する誘導電流を使用する方法においては、炉本体の外周面にトロリー線やコイルを巻回する必要があり、設備が大型化して製造コストが高くなってしまう。特に、炉本体の直径が５ｍを超えるものでは設置が困難である。
また、送信機にバッテリーを組み込む方法においては、バッテリーの寿命によって交換作業が必要となり、この交換作業のためにロータリーキルン炉の操業を停止することになる。この交換作業によって、操業効率が低下するとともに、炉本体を構成する耐火物層が温度変化によって劣化してしまうおそれがあった。 By the way, in the method of winding the trolley wire around the outer peripheral surface of the furnace body and supplying electric power from the slip ring of the power supply apparatus, or the method of using the induced current generated by winding the coil around the furnace body and bringing the secondary coil close However, it is necessary to wind a trolley wire or a coil around the outer peripheral surface of the furnace body, which increases the size of the equipment and increases the manufacturing cost. In particular, installation is difficult when the diameter of the furnace body exceeds 5 m.
Further, in the method of incorporating the battery into the transmitter, replacement work is required depending on the life of the battery, and the operation of the rotary kiln furnace is stopped for this replacement work. Due to this replacement work, the operation efficiency is lowered, and the refractory layer constituting the furnace body may be deteriorated due to the temperature change.

本発明は、前述した状況に鑑みてなされたものであって、炉本体の内部温度を正確に測定できるとともに、低コストで設置でき、かつ、バッテリー交換作業が不要なロータリーキルン炉用温度測定装置及びこの温度測定装置を備えたロータリーキルン炉を提供することを目的とする。   The present invention has been made in view of the situation described above, and can accurately measure the internal temperature of the furnace body, can be installed at low cost, and does not require battery replacement work, and a temperature measuring device for a rotary kiln furnace and It aims at providing the rotary kiln furnace provided with this temperature measuring device.

この課題を解決するために、本発明のロータリーキルン炉用温度測定装置は、ロータリーキルン炉の炉本体の内部温度を測定するためのロータリーキルン炉用温度測定装置であって、前記炉本体の内部に感温部が配置される温度センサと、前記炉本体に配設されて前記温度センサの測定データを送信する送信機と、この送信機から送信された前記測定データを受信する受信機と、前記炉本体からの放熱を回収して前記送信機へ電力を供給する熱電池と、を備えていることを特徴としている。   In order to solve this problem, the temperature measuring device for a rotary kiln furnace of the present invention is a temperature measuring device for a rotary kiln furnace for measuring the internal temperature of the furnace body of the rotary kiln furnace, and the temperature sensing device is provided inside the furnace body. A temperature sensor in which a section is disposed, a transmitter disposed in the furnace body and transmitting measurement data of the temperature sensor, a receiver receiving the measurement data transmitted from the transmitter, and the furnace body And a thermal battery for recovering heat radiation from the power source and supplying electric power to the transmitter.

In addition, since the transmitter and the heat release plate are stacked with a space therebetween, heat dissipation from the heat release plate can be promoted, and the portion connected to the heat absorption plate and the portion connected to the heat release plate in the thermoelectric element It is possible to improve the power generation efficiency by increasing the temperature difference. Furthermore, the transmitter is disposed at a position away from the furnace body, and the transmitter can be prevented from being deteriorated by heat.

また、前記熱吸収板を、前記炉本体の外表面と間隔をあけて配設し、前記熱吸収板と前記炉本体の外表面との間に、通風孔を有する筒部を設けてもよい。
この場合、筒部によって炉本体と熱吸収板との間を囲むことで炉本体からの熱の回収を促進でき、熱電池の発電効率の向上を図ることができる。また、筒部の側壁に通風孔が設けられているので、屋外に設置されたロータリーキルン炉にこの温度測定装置を配設した場合に強風などで筒部が損傷することを抑制できる。 Moreover, the said heat absorption board may be arrange | positioned at intervals with the outer surface of the said furnace main body, and the cylinder part which has a ventilation hole between the said heat absorption board and the outer surface of the said furnace main body may be provided. .
In this case, it is possible to promote the recovery of heat from the furnace body by surrounding the furnace body and the heat absorption plate with the cylindrical portion, and to improve the power generation efficiency of the thermal battery. Moreover, since the ventilation hole is provided in the side wall of a cylinder part, when this temperature measuring apparatus is arrange | positioned in the rotary kiln furnace installed outdoors, it can suppress that a cylinder part is damaged by a strong wind.

さらに、前記熱放出板に、放熱フィンを立設してもよい。
この場合、熱放出板からの放熱を促進させることで、熱吸収板と熱放出板との温度差を大きくして熱電池のさらなる発電効率の向上を図ることができる。 Furthermore, a heat radiating fin may be erected on the heat releasing plate.
In this case, by promoting heat dissipation from the heat release plate, the temperature difference between the heat absorption plate and the heat release plate can be increased to further improve the power generation efficiency of the thermal battery.

炉本体２を軸線Ｌを中心として回転させるとともに、燃焼バーナー（図示なし）を点火して炉本体２２の内部を８００〜１２００℃程度に加熱する。この状態で、被処理物Ｗを投入部７によって炉本体２の内部に投入する。すると、炉本体２の内部に投入された被処理物Ｗは、高温とされた炉本体２内部で、可燃物が分解されてガス化するとともに、金属を含む不燃性成分が溶融状態または半溶融状態のスラグとなる。これらの生成ガスおよび生成スラグは、ロータリーキルン炉１の下流側に設けられた処理装置（図示なし）へと搬送されて処理される。なお、燃焼バーナーにより炉本体２の内部温度が安定したら、燃焼バーナーを止め、被処理物Ｗの燃焼によって生じる熱を利用して炉本体２の内部温度を維持していく。 The high temperature processing method of the to-be-processed object W by the rotary kiln furnace 1 provided with the temperature measuring apparatus 10 of such a structure is demonstrated.
While rotating the furnace body 2 around the axis L, a combustion burner (not shown) is ignited to heat the interior of the furnace body 22 to about 800 to 1200 ° C.

These generated gas and generated slag are conveyed to a processing device (not shown) provided on the downstream side of the rotary kiln furnace 1 for processing. When the internal temperature of the furnace body 2 is stabilized by the combustion burner, the combustion burner is stopped and the internal temperature of the furnace body 2 is maintained using heat generated by the combustion of the workpiece W.

ここで、温度測定装置１０により炉本体２の内部温度が連続的に測定され、送信機１２から受信機１３へと測定データが送られる。この測定データに基いて投入量制御部８及び空気量制御部６は、被処理物Ｗの投入量及び炉本体２内部への空気の供給量を制御する。具体的には、炉本体２の内部温度が低下した場合には、被処理物Ｗの投入量の増加又は空気供給量の増加により、炉本体２内部での燃焼を促す。一方、炉本体２の内部温度が上昇した場合には、被処理物Ｗの投入量の低減又は空気供給量の低減により、炉本体２内部での燃焼を抑える。これにより、炉本体２の内部温度が調整される。   Here, the internal temperature of the furnace body 2 is continuously measured by the temperature measuring device 10, and measurement data is sent from the transmitter 12 to the receiver 13. Based on this measurement data, the input amount control unit 8 and the air amount control unit 6 control the input amount of the workpiece W and the supply amount of air into the furnace body 2. Specifically, when the internal temperature of the furnace body 2 decreases, combustion in the furnace body 2 is promoted by increasing the input amount of the workpiece W or increasing the air supply amount. On the other hand, when the internal temperature of the furnace body 2 rises, combustion in the furnace body 2 is suppressed by reducing the input amount of the workpiece W or reducing the air supply amount. Thereby, the internal temperature of the furnace main body 2 is adjusted.

本発明の第１の実施形態であるロータリーキルン炉用温度測定装置１０によれば、炉本体２に配設された送信機１２に電力を供給するために、炉本体２からの放熱を回収して発電する熱電池１４が備えられているので、バッテリー交換をすることなく送信機１２を作動させて連続的に測定データを得ることが可能となる。よって、低コストで温度測定装置１０を配設することができるとともに、バッテリー交換作業による操業効率の低下を防止できる。   According to the rotary kiln furnace temperature measuring apparatus 10 according to the first embodiment of the present invention, in order to supply power to the transmitter 12 disposed in the furnace body 2, the heat radiation from the furnace body 2 is recovered. Since the thermal battery 14 for generating electricity is provided, it becomes possible to operate the transmitter 12 and obtain measurement data continuously without replacing the battery. Therefore, it is possible to arrange the temperature measuring device 10 at low cost, and it is possible to prevent a decrease in operation efficiency due to battery replacement work.

また、熱電池１４が、炉本体２側に配置される熱吸収板１５と、この熱吸収板１５と対向配置される熱放出板１６と、これら熱吸収板１５と熱放出板１６の間に配設された熱電素子１７とを備えており、送信機１２が熱放出板１６の外側に設けられた台座１８の上に配置されているので、温度測定装置１０自体を小型化することができ、炉本体２への配設作業を容易にすることができる。また、送信機１２と熱放出板１６との間に台座１８によって空間が画成されているので、熱放出板１６からの放熱を促進でき、熱電素子１７において熱吸収板１５に接続された部分と熱放出板１６に接続された部分との温度差を大きくして発電効率を向上させることができる。さらに、送信機１２が炉本体２から離間した位置に配設されることになり、送信機１２の熱による劣化を防止できる。   In addition, the thermal battery 14 includes a heat absorption plate 15 disposed on the furnace body 2 side, a heat release plate 16 disposed opposite to the heat absorption plate 15, and between the heat absorption plate 15 and the heat release plate 16. Since the transmitter 12 is disposed on a pedestal 18 provided outside the heat release plate 16, the temperature measuring device 10 itself can be reduced in size. In addition, it is possible to facilitate the disposition work to the furnace body 2. In addition, since a space is defined by the pedestal 18 between the transmitter 12 and the heat dissipation plate 16, heat radiation from the heat dissipation plate 16 can be promoted, and the portion connected to the heat absorption plate 15 in the thermoelectric element 17. And the portion connected to the heat release plate 16 can be increased to improve the power generation efficiency. Furthermore, the transmitter 12 is disposed at a position away from the furnace body 2, and the transmitter 12 can be prevented from being deteriorated by heat.

特に本実施形態においては、熱放出板１６と送信機１２との距離Ｌ１が、１０ｍｍ≦Ｌ１≦２００ｍｍの範囲内に設定され、本実施形態ではＬ１＝８０ｍｍとされているので、熱放出板１６と送信機１２（天板部１８Ａ）との間の空間を確保して熱の放出を確実に促進できるとともに、送信機１２が炉本体２の径方向外側に向けて大きく突出することがなく、送信機１２の衝突等を防止できる。   In particular, in the present embodiment, the distance L1 between the heat release plate 16 and the transmitter 12 is set within a range of 10 mm ≦ L1 ≦ 200 mm, and in this embodiment, L1 = 80 mm. The space between the transmitter 12 (top plate portion 18A) can be secured and the release of heat can be surely promoted, and the transmitter 12 does not protrude greatly outward in the radial direction of the furnace body 2, The collision of the transmitter 12 can be prevented.

さらに、炉本体２の外表面と熱電池１４（熱吸収板１５）との間の距離Ｌ２が、０≦Ｌ２≦６００ｍｍ、より望ましくは１００ｍｍ≦Ｌ２≦３００ｍｍの範囲内に設定され、本実施形態ではＬ２＝１００ｍｍとされているので、炉本体２の外表面からの放熱を効率良く吸収することができる。   Further, the distance L2 between the outer surface of the furnace body 2 and the thermal battery 14 (heat absorption plate 15) is set within the range of 0 ≦ L2 ≦ 600 mm, more preferably 100 mm ≦ L2 ≦ 300 mm, and this embodiment Since L2 = 100 mm, the heat radiation from the outer surface of the furnace body 2 can be efficiently absorbed.

次に、本発明の第２の実施形態について添付した図面を参照にして説明する。図５に、本発明の第２の実施形態であるロータリーキルン炉用温度測定装置２０を示す。

熱吸収板２５は、セラミックス板とされ、直径３００ｍｍ、厚さ５ｍｍの円板状をなし、熱放出板２６は、ステンレス板とされ、直径３００ｍｍ、厚さ５ｍｍの円板状をなし、熱電素子２７は、直径３００ｍｍ、厚さ１０ｍｍの円板状をなしている。
熱電池２４（熱放出板２６）と送信機２２との間に配置された台座２８は、天板部２８Ａと脚部２８Ｂとを備えており、天板部２８Ａは円板状とされ、直径２００ｍｍ，厚さ５ｍｍのステンレス板とされている。 The heat absorption plate 25 is a ceramic plate and has a disk shape with a diameter of 300 mm and a thickness of 5 mm. The heat release plate 26 is a stainless steel plate with a disk shape with a diameter of 300 mm and a thickness of 5 mm. 27 has a disk shape with a diameter of 300 mm and a thickness of 10 mm.
A pedestal 28 disposed between the thermal battery 24 (heat release plate 26) and the transmitter 22 includes a top plate portion 28A and a leg portion 28B, and the top plate portion 28A has a disk shape and a diameter. The stainless steel plate is 200 mm and 5 mm thick.

熱電池２４（熱放出板２６）と送信機２２との間の距離Ｌ１は、１０ｍｍ≦Ｌ１≦２００ｍｍの範囲内に設定され、本実施形態ではＬ１＝５０ｍｍとされている。
一方、炉本体２の外表面と熱電池２４（熱吸収板２５）との間にはスペーサ（図示なし）が配置されており、炉本体２の外表面と熱電池２４（熱吸収板２５）との間の距離Ｌ２は、０≦Ｌ２≦６００ｍｍ、より望ましくは１００ｍｍ≦Ｌ２≦３００ｍｍの範囲内に設定され、本実施形態ではＬ２＝１５０ｍｍとされている。 A distance L1 between the thermal battery 24 (heat release plate 26) and the transmitter 22 is set within a range of 10 mm ≦ L1 ≦ 200 mm, and in this embodiment, L1 = 50 mm.
On the other hand, a spacer (not shown) is disposed between the outer surface of the furnace body 2 and the thermal battery 24 (heat absorption plate 25), and the outer surface of the furnace body 2 and the thermal battery 24 (heat absorption plate 25). Is set within a range of 0 ≦ L2 ≦ 600 mm, more preferably 100 mm ≦ L2 ≦ 300 mm, and in this embodiment, L2 = 150 mm.

そして、炉本体２の外表面と熱電池２４（熱吸収板２５）との間には、円筒部３０が配設されている。この円筒部３０は、前記熱吸収板２５と同じく直径３００ｍｍ、高さ１５０ｍｍとされており、その側壁に貫通した通風孔３１が複数形成されている。   A cylindrical portion 30 is disposed between the outer surface of the furnace body 2 and the thermal battery 24 (heat absorption plate 25). The cylindrical portion 30 has a diameter of 300 mm and a height of 150 mm, similar to the heat absorbing plate 25, and a plurality of ventilation holes 31 penetrating the side wall are formed.

このような構成とされた本発明の第２の実施形態であるロータリーキルン炉用温度測定装置２０によれば、円筒部３０によって炉本体２と熱電池２４の熱吸収板２５との間が取り囲まれているので、炉本体２からの放熱を熱吸収板２５によって効率的に回収でき、熱電池２４の発電効率の向上を図ることができる。また、この円筒部３０の側壁に複数の通風孔３１が形成されているので、屋外に設置されたロータリーキルン炉にこの温度測定装置２０を配設した場合でも強風などで円筒部３０が損傷することを抑制できる。   According to the rotary kiln furnace temperature measuring apparatus 20 having the above-described configuration according to the second embodiment of the present invention, the cylindrical body 30 surrounds the furnace body 2 and the heat absorption plate 25 of the thermal battery 24.

次に、本発明の第３の実施形態について添付した図面を参照にして説明する。図６に、本発明の第３の実施形態であるロータリーキルン炉用温度測定装置を示す。
