Description

本発明は、焼却設備のガス処理装置に関する。   The present invention relates to a gas treatment device for incineration facilities.

廃棄物やリサイクル物の処理には、ロータリーキルン炉が組み込まれた焼却装置が用いられている。ロータリーキルン炉は、耐火材を内張りした横型円筒炉である。この円筒炉は、定速回転することができる。円筒炉の中心軸はわずかに傾斜しており、炉内の焼却物又は被加熱物は、円筒炉の回転により、中心軸の傾斜勾配に従って炉内を移動する。円筒炉の一端には、炉内に投入された焼却物や被加熱物を焼却するためにバーナが配設されている。円筒炉内で焼却物や被加熱物を焼却すると未燃焼ガスが発生する。この未燃焼ガスは２次焼却炉へ送られて、完全燃焼させられる。   An incinerator incorporating a rotary kiln furnace is used to treat waste and recycled materials. The rotary kiln furnace is a horizontal cylindrical furnace lined with a refractory material. This cylindrical furnace can rotate at a constant speed. The central axis of the cylindrical furnace is slightly inclined, and the incineration object or the object to be heated in the furnace moves in the furnace according to the inclination gradient of the central axis by the rotation of the cylindrical furnace. A burner is disposed at one end of the cylindrical furnace in order to incinerate the incinerated material and the object to be heated. When the incineration object or the object to be heated is incinerated in the cylindrical furnace, unburned gas is generated. This unburned gas is sent to the secondary incinerator for complete combustion.

ところが、２次焼却炉内の酸素が不足する場合や、円筒炉において未燃焼ガスが多量に発生した場合には、２次焼却炉内で未燃焼ガスを完全燃焼することができない。未燃焼ガスには微小粉塵が含まれており、この微小粉塵の一部は、高温の火の粉となり、２次焼却炉の下流側に設置されているバグフィルタの濾布に付着し、濾布を焼損させる問題がある。   However, when oxygen in the secondary incinerator is insufficient or when a large amount of unburned gas is generated in the cylindrical furnace, the unburned gas cannot be completely burned in the secondary incinerator. The unburned gas contains fine dust, and a part of this fine dust becomes high-temperature fire powder and adheres to the filter cloth of the bag filter installed downstream of the secondary incinerator. There is a problem of burning.

一方、焼却炉における排出ガスを完全燃焼し、煙、粉塵、火の粉等を外部へ排出しない廃棄物処理装置が特許文献１に開示されている。   On the other hand, Patent Document 1 discloses a waste treatment apparatus that completely burns exhaust gas in an incinerator and does not discharge smoke, dust, sparks, or the like to the outside.

再公表特許公報ＷＯ２００５／１０８８６６Republished Patent Publication WO2005 / 108866

特許文献１に開示されている廃棄物処理装置は、未燃焼ガスを完全燃焼させるので、煙、粉塵、火の粉等を排出しない。ところが、処理する廃棄物によっては、未燃焼ガスを完全燃焼することができない場合が考えられる。このような廃棄物処理装置は、未燃焼ガスを完全燃焼することができない場合を想定したものでない。   Since the waste disposal apparatus disclosed in Patent Document 1 completely burns unburned gas, smoke, dust, sparks, etc. are not discharged. However, depending on the waste to be treated, there may be a case where the unburned gas cannot be completely burned. Such a waste treatment apparatus is not intended for the case where unburned gas cannot be completely burned.

そこで、本発明は、上記の課題を鑑み、簡易な構成により、未燃焼ガス等に含まれる微小粉塵を取り除くことを課題とする。   Then, this invention makes it a subject to remove the fine dust contained in unburned gas etc. by simple structure in view of said subject.

かかる課題を解決する本発明のガス処理装置は、微小粉塵・火の粉を含むガスが通過する管と、当該管内のガス流中に懸垂された遮蔽物と、を備えたことを特徴とする。このような構成とすることにより、管内を流れるガスに含まれる微小粉塵は、遮蔽物に衝突する。この結果、微小粉塵をガス中から取り除くことができる。また、遮蔽物はガス流路中で揺れ動き、微小粉塵が付着せずに下方に落下する。従って、遮蔽物に微小粉塵が付着して、流路を遮断することが抑制できる。このような遮蔽物は、ガス流中に懸垂された鎖とすることができる。   The gas processing apparatus of the present invention that solves such a problem is characterized by including a pipe through which a gas containing fine dust and sparks passes and a shield suspended in a gas flow in the pipe. By setting it as such a structure, the fine dust contained in the gas which flows through the inside of a pipe collides with a shield. As a result, fine dust can be removed from the gas. Further, the shield swings in the gas flow path and falls downward without attaching fine dust. Therefore, it is possible to prevent the fine dust from adhering to the shield and blocking the flow path. Such a shield can be a chain suspended in the gas stream.

上記の課題を解決する本発明のキルン処理装置は、樹脂付金銀滓原料を焼却するキルン炉と、当該キルン炉の下流に配置した２次燃焼炉と、当該２次燃焼炉の下流に配置した冷却塔と、当該冷却塔の出口に接続された排気管と、当該排気管の下流に接続したバグフィルタと、前記排気管内のガス流中に懸垂された遮蔽物と、を備えたことを特徴とする。冷却塔から排出されるガスに含まれる微小粉塵は、火の粉となってバグフィルタの濾布を焼損するおそれがある。本発明の粉状原料のキルン処理装置は、冷却塔から排出されるガスから、ガスに含まれる微小粉塵を取り除く。これにより、バグフィルタの濾布の焼損を抑制することができる。   The kiln processing apparatus of the present invention that solves the above-mentioned problems is arranged in a kiln furnace for incinerating a resin-attached gold and silver coffin raw material, a secondary combustion furnace arranged downstream of the kiln furnace, and a downstream of the secondary combustion furnace. A cooling tower, an exhaust pipe connected to the outlet of the cooling tower, a bag filter connected downstream of the exhaust pipe, and a shield suspended in the gas flow in the exhaust pipe And The fine dust contained in the gas discharged from the cooling tower may become a spark and burn the filter cloth of the bag filter. The powder raw material kiln treatment apparatus of the present invention removes fine dust contained in a gas from a gas discharged from a cooling tower. Thereby, the burnout of the filter cloth of the bag filter can be suppressed.

本発明の樹脂付金銀滓原料のキルン処理方法は、樹脂付金銀滓原料をキルン炉において燃焼し、前記キルン炉で発生する未燃焼ガスを、前記キルン炉の下流に配置した二次燃焼炉において加熱処理し、前記二次燃焼炉において加熱したガスを、前記二次燃焼炉の下流に配置した冷却塔に導入して冷却し、前記冷却塔から排出されるガスに残存する火の粉を、前記冷却塔の出口に懸垂された遮蔽物により取り除くことを特徴とする。   The kiln treatment method for a resin-attached gold and silver soot raw material of the present invention is a method in which a resin-attached gold and silver soot raw material is burned in a kiln furnace, and unburned gas generated in the kiln furnace is disposed downstream of the kiln furnace. The gas heated and heated in the secondary combustion furnace is introduced into a cooling tower disposed downstream of the secondary combustion furnace and cooled, and the sparks remaining in the gas discharged from the cooling tower are cooled. It is removed by a shield suspended at the exit of the tower.

本発明は、簡易な構成により、ガス中に含まれる微小粉塵を取り除くことができる。   The present invention can remove fine dust contained in gas with a simple configuration.

以下、本発明を実施するための最良の形態を図面と共に説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

本発明の実施例１について図面を参照しつつ説明する。図１は本発明のキルン処理装置１の概要を示した説明図である。   Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing an outline of a kiln processing apparatus 1 of the present invention.

キルン処理装置１は、キルン炉２と、２次燃焼炉３と、冷却塔４と、バグフィルタ５とを備えている。   The kiln processing apparatus 1 includes a kiln furnace 2, a secondary combustion furnace 3, a cooling tower 4, and a bag filter 5.

キルン炉２はロータリー型の横型円筒炉である。キルン炉２の一端には、例えば、粉砕後の基板、携帯電話等のリサイクル製品のような樹脂付金銀滓原料を炉内に投入する投入口２１と、投入された樹脂付金銀滓原料を焼却するためのバーナ２２とが配設されている。キルン炉２では、投入された樹脂付金銀滓原料を６００℃から７００℃の温度下で３０分から１時間かけて燃焼する。この結果、燃焼された高温のガスと焼却残渣とが生成される。   The kiln furnace 2 is a rotary horizontal cylindrical furnace. At one end of the kiln furnace 2, for example, an inlet 21 for introducing a resin-added gold and silver rice bran raw material such as a crushed substrate and a recycled product such as a mobile phone into the furnace, and injecting the resin-added gold and silver rice bran raw material into A burner 22 is provided. In the kiln furnace 2, the charged gold / silver candy raw material with resin is burned at a temperature of 600 ° C. to 700 ° C. for 30 minutes to 1 hour. As a result, burned hot gas and incineration residue are generated.

２次燃焼炉３はキルン炉２で発生した未燃ガスを燃焼させる。２次燃焼炉３はキルン炉２の下流に配置されている。キルン炉２内の樹脂付金銀滓原料の燃焼により発生したガスは、２次燃焼炉３へ導入される。２次燃焼炉３は、炉内を８００℃から１２００℃に加熱し、導入されたガスに含まれる未燃ガスを燃焼させる。   The secondary combustion furnace 3 burns unburned gas generated in the kiln furnace 2. The secondary combustion furnace 3 is disposed downstream of the kiln furnace 2. The gas generated by the combustion of the resin-attached gold and silver soot raw material in the kiln furnace 2 is introduced into the secondary combustion furnace 3. The secondary combustion furnace 3 heats the inside of the furnace from 800 ° C. to 1200 ° C. and burns the unburned gas contained in the introduced gas.

冷却塔４は２次燃焼炉３で燃焼したガスを冷却する。冷却塔４は２次燃焼炉３の下流に配置されている。２次燃焼炉３内で燃焼したガスは冷却塔４へ導入される。冷却塔４内には、冷却水を噴射するスプレー４１が備えられており、冷却塔４内に導入されたガスへ冷却水が噴射される。これにより、冷却塔４内に導入されたガスは、２００℃以下に冷却される。冷却塔４内を通過したガスは以降２００℃以下となって下流側へ流れていく。   The cooling tower 4 cools the gas burned in the secondary combustion furnace 3. The cooling tower 4 is disposed downstream of the secondary combustion furnace 3. The gas burned in the secondary combustion furnace 3 is introduced into the cooling tower 4. A spray 41 for injecting cooling water is provided in the cooling tower 4, and the cooling water is injected into the gas introduced into the cooling tower 4. Thereby, the gas introduced into the cooling tower 4 is cooled to 200 ° C. or lower. After that, the gas that has passed through the cooling tower 4 becomes 200 ° C. or lower and flows downstream.

冷却塔４の下部には、冷却したガスを排出する出口４２が形成されている。この出口には排気管６が接続されている。排気管６の下流には、バグフィルタ５が接続されている。バグフィルタ５は、吊り下げられた濾布５１によりガス内の粉塵を捕集する濾過装置である。濾布５１を通過したガスは、粉塵が取り除かれ、洗浄空気として取り出される。このようにバグフィルタ５を通り抜けた洗浄空気は、キルン処理装置１の外部へ排出される。一方、ガス中から取り除かれた粉塵は、バグボックス５２へ堆積する。   An outlet 42 for discharging the cooled gas is formed in the lower part of the cooling tower 4. An exhaust pipe 6 is connected to the outlet. A bag filter 5 is connected downstream of the exhaust pipe 6. The bag filter 5 is a filtration device that collects dust in the gas using a suspended filter cloth 51. Dust is removed from the gas that has passed through the filter cloth 51 and is taken out as cleaning air. The cleaning air that has passed through the bag filter 5 in this manner is discharged to the outside of the kiln processing apparatus 1. On the other hand, the dust removed from the gas accumulates in the bag box 52.

さらに、キルン処理装置１は、排気管６の冷却塔４の出口４２側に懸垂された複数の鎖７を備えている。この鎖７は、材質ＳＵＳ３０４、線径５ｍｍ、長さ４００ｍｍから６００ｍｍのステンレスチェーンである。この懸垂された鎖７は、排気管６内を通過するガス中に含まれる微小粉塵をガス中から取り除く遮蔽物である。ガス中の微小粉塵は鎖７に衝突することにより、ガスから取り除かれる。なお、このような鎖７に代えて、排気管６内に、棒状、板状の遮蔽物を揺動可能に吊り下げた構成とすることもできる。要は、遮蔽物が排気管６内に揺動可能に懸垂されていれば良い。   Furthermore, the kiln processing apparatus 1 is provided with a plurality of chains 7 suspended on the outlet 42 side of the cooling tower 4 of the exhaust pipe 6. The chain 7 is a stainless steel chain having a material SUS304, a wire diameter of 5 mm, and a length of 400 mm to 600 mm. The suspended chain 7 is a shield that removes fine dust contained in the gas passing through the exhaust pipe 6 from the gas. The fine dust in the gas is removed from the gas by striking the chain 7. Instead of such a chain 7, a rod-like or plate-like shield can be swingably suspended in the exhaust pipe 6. In short, it is sufficient that the shield is suspended in the exhaust pipe 6 so as to be swingable.

図２は、鎖７が懸垂されている排気管６の一部を拡大して示した説明図である。図２（ａ）は、排気管６を横側から見た断面図であり、図２（ｂ）は、排気管６を上側から見た断面図であり、図２（ｃ）は、冷却塔４側から排気管６内を見た断面図である。   FIG. 2 is an explanatory view showing an enlarged part of the exhaust pipe 6 on which the chain 7 is suspended. 2A is a cross-sectional view of the exhaust pipe 6 viewed from the side, FIG. 2B is a cross-sectional view of the exhaust pipe 6 viewed from the upper side, and FIG. 2C is a cooling tower. It is sectional drawing which looked at the inside of the exhaust pipe 6 from the 4th side.

図２（ｂ）に示すように、鎖７はガスの進行方向に対して４列に懸垂されている。懸垂された鎖７の列を、冷却塔４に近い側から、第１列目７１、第２列目７２、第３列目７３、第４列目７４とし、第１列目７１の鎖と第２列目７２の鎖、第２列目７２の鎖と第３列目７３の鎖、第３列目７３の鎖と第４列目７４の鎖は、それぞれ１５０ｍｍ離れて並んでいる。   As shown in FIG. 2B, the chains 7 are suspended in four rows with respect to the gas traveling direction. The suspended row of chains 7 is designated as the first row 71, the second row 72, the third row 73, and the fourth row 74 from the side close to the cooling tower 4, and the first row 71 chain and The second row 72 chain, the second row 72 chain and the third row 73 chain, and the third row 73 chain and the fourth row 74 chain are arranged 150 mm apart.

また、第１列目７１にはガスの流路上の中央に４本の鎖７が１００ｍｍの間隔を空けて並んでいる。第２列目７２、第３列目７３、第４列目７４の鎖７は、排気管６のガスの流路上全体に亘って、１００ｍｍの間隔を空けて並んでいる。本実施例では、１０本の鎖７により、ガスの流路全体を覆う。   In the first row 71, four chains 7 are arranged in the center of the gas flow path with an interval of 100 mm. The chains 7 of the second row 72, the third row 73, and the fourth row 74 are arranged at an interval of 100 mm over the entire gas flow path of the exhaust pipe 6. In this embodiment, the ten gas chains 7 cover the entire gas flow path.

さらに、隣り合う鎖７の列は、千鳥状に並んでいる。言い換えると、ガスの流れ方向、すなわち、冷却塔６側から見て、上流側の列に並ぶ鎖７の隙間に次の列の鎖７が懸垂されている。   Furthermore, the row | line | column of the adjacent chain | strand 7 is located in a zigzag form. In other words, the chain 7 in the next row is suspended in the gap between the chains 7 arranged in the upstream row when viewed from the gas flow direction, that is, from the cooling tower 6 side.

排気管６の鎖７が懸垂された部分の側面には、直径６００ｍｍのマンホール６１が形成されている。通常、このマンホール６１は蓋６２で塞がれているが、作業時に蓋６２を開けて排気管６内に進入することができる。   A manhole 61 having a diameter of 600 mm is formed on the side surface of the portion of the exhaust pipe 6 where the chain 7 is suspended. Normally, the manhole 61 is closed with a lid 62, but the lid 62 can be opened during operation to enter the exhaust pipe 6.

次に、本発明のキルン処理装置１の作用を説明する。   Next, the operation of the kiln processing apparatus 1 of the present invention will be described.

２次燃焼炉３から排出されるガスには粉塵が含まれ、このような粉塵は冷却塔４を通過したガスにも含まれている。このガスは排気管６内を流れ、鎖７の懸垂された空間を通過する。この際、ガスに含まれていた粉塵は、鎖７に衝突してガスから取り除かれる。この鎖７はガスの進行方向に対して４列に懸垂されているため、粉塵がいずれかの鎖７に衝突する割合が高くなり、粉塵を捕集しやすい。また、上流側の列に並ぶ鎖７の隙間に次の列の鎖７が懸垂されているため、上流側の列の鎖７の隙間を抜けたガスが次の列に懸垂された鎖７に衝突しやすく、粉塵を捕集しやすい。   The gas discharged from the secondary combustion furnace 3 includes dust, and such dust is also included in the gas that has passed through the cooling tower 4. This gas flows through the exhaust pipe 6 and passes through the suspended space of the chain 7. At this time, the dust contained in the gas collides with the chain 7 and is removed from the gas. Since the chains 7 are suspended in four rows with respect to the gas traveling direction, the ratio of the dust colliding with any of the chains 7 is increased, and the dust is easily collected. Further, since the next row of chains 7 is suspended in the gap between the chains 7 arranged in the upstream row, the gas that has passed through the gap in the upstream row 7 is suspended in the next suspended row 7. Easy to collide and easily collect dust.

さらに、ガスが通過する際に、懸垂されている鎖７は揺れるため、衝突した粉塵が鎖７に付着しにくい。このため、粉塵が鎖７に付着して、排気管６の流路面積を縮小することが抑制される。鎖７に衝突したガス中の粉塵は、排気管６内に懸垂された鎖７の下側６３に堆積する。このように鎖７の下側６３に堆積した粉塵は定期的に排気管６内から取り除かれる。この粉塵の除去作業は、マンホール６１を開けて人為的に行う。また、粉塵の除去を機械的に行う構成を組み込んでもよい。   Furthermore, since the suspended chain 7 shakes when the gas passes, the collided dust hardly adheres to the chain 7. For this reason, it is suppressed that dust adheres to the chain 7 and the flow passage area of the exhaust pipe 6 is reduced. Dust in the gas that collides with the chain 7 accumulates on the lower side 63 of the chain 7 suspended in the exhaust pipe 6. Thus, the dust accumulated on the lower side 63 of the chain 7 is periodically removed from the exhaust pipe 6. This dust removal operation is performed manually by opening the manhole 61. Moreover, you may incorporate the structure which removes dust mechanically.

次に本発明のキルン処理装置１の粉塵回収について説明する。図３は本発明のキルン処理装置１において懸垂された鎖７の下側６３とバグボックス５２とにおいて、一日に堆積し回収される粉塵の量を示した表である。図３では、比較例として、従来のキルン処理装置のバグボックスにおける粉塵回収量も示している。   Next, the dust collection | recovery of the kiln processing apparatus 1 of this invention is demonstrated. FIG. 3 is a table showing the amount of dust accumulated and collected in one day on the lower side 63 of the chain 7 suspended in the kiln processing apparatus 1 of the present invention and the bag box 52. FIG. 3 also shows the amount of dust collected in a bag box of a conventional kiln processing apparatus as a comparative example.

図３に示すように、本発明のキルン処理装置１では、鎖７を排気管６内に懸垂させることにより、鎖７の下側６３において、排気管４を通過するガスに含まれる粉塵の総量の４％ほどの粉塵が捕集されている。なお、このとき、排気管６を通過する排ガス量は、７０００Ｎｍ３／ｈから９０００Ｎｍ３／ｈである。 As shown in FIG. 3, in the kiln processing apparatus 1 of the present invention, the total amount of dust contained in the gas passing through the exhaust pipe 4 on the lower side 63 of the chain 7 by suspending the chain 7 in the exhaust pipe 6. About 4% of the dust is collected. At this time, the amount of exhaust gas passing through the exhaust pipe 6 is 7000 Nm 3 / h to 9000 Nm 3 / h.

このように粉塵をバグフィルタ５の上流側で取り除くことにより、冷却塔４内で冷却されずに通過した火の粉が、バグフィルタ５内の濾布５１へ到達することが抑制される。この結果、濾布５１の焼損が抑制される。実際に、本発明のキルン処理装置１を運転した結果、従来のキルン処理装置において、月に、１、２度みられた濾布の焼損トラブルが解消された。   By removing the dust on the upstream side of the bag filter 5 in this way, it is possible to suppress the fire powder that has passed without being cooled in the cooling tower 4 from reaching the filter cloth 51 in the bag filter 5. As a result, burnout of the filter cloth 51 is suppressed. Actually, as a result of operating the kiln treatment apparatus 1 of the present invention, in the conventional kiln treatment apparatus, the trouble of burning the filter cloth observed once or twice a month was solved.

以上のように、本発明のキルン処理装置１は、排気管６内のガス流中に懸垂された鎖７を備えたことにより、排気管６内を通過するガス中の微小粉塵を取り除くことができる。これにより、粉塵の一部が火の粉となってバグフィルタ５へ侵入して濾布５１を焼損することを抑制できる。   As described above, the kiln processing apparatus 1 of the present invention includes the chain 7 suspended in the gas flow in the exhaust pipe 6, thereby removing the fine dust in the gas passing through the exhaust pipe 6. it can. Thereby, it can suppress that a part of dust turns into the bug filter 5 as a fire powder and burns out the filter cloth 51.

また、キルン処理装置１の排気管６、排気管６内に懸垂された鎖７は本発明の排気処理装置に相当する。このように排気管６に鎖７を取り付けるような簡易な構成により、ガス中に含まれる微小粉塵を取り除くことができる。   The exhaust pipe 6 of the kiln treatment apparatus 1 and the chain 7 suspended in the exhaust pipe 6 correspond to the exhaust treatment apparatus of the present invention. In this way, with a simple configuration in which the chain 7 is attached to the exhaust pipe 6, the fine dust contained in the gas can be removed.
