この考案は、硫化金属鉱の非鉄製錬用排熱ボイ
ラーにおけるスーツブロワーシーリング部のシー
ル構造を改良したスーツブロワーウオールボツク
スに関するものである。[Detailed Description of the Invention] This invention relates to a suit blower wall box in which the sealing structure of the soot blower sealing part in a waste heat boiler for non-ferrous smelting of metal sulfide ores is improved.
従来、この種のスーツブロワーウオールボツク
スの組立構造は第１図に示すようにスーツブロワ

入管４が接続されてウオールボツクス２内にシー
ルエアーが導入される構造となつている。 Conventionally, in the assembly structure of this type of suit blower wall box, as shown in FIG. Scrapers 3, 3 are attached to the entrance and exit portion of the door 1, and a sealing air introduction pipe 4 is connected to introduce sealing air into the wall box 2.
また、上記ウオールボツクス２は、本体５にデ
イスタンスピース６、スプリング７、カバー８、
及びガスケツト９がボルト等により取り付けられ
た構造になつており、スーツブロワーロツド１に
付着した煙灰等をスクレーパ３，３で掻き落すも
のである。 The wall box 2 also includes a main body 5, a distance piece 6, a spring 7, a cover 8,
A gasket 9 is attached to the soot blower rod 1 by bolts or the like, and smoke ash and the like adhering to the soot blower rod 1 are scraped off by scrapers 3, 3.
従つて、上記ウオールボツクス２内に導入され
た低圧のシールエアーはスーツブロワーロツド１
とスクレーパ３，３の隙間から炉内に噴出させて
ウオールボツクス２内に煙灰等を入れないように
なつている。 Therefore, the low pressure seal air introduced into the wall box 2 is transferred to the suit blower rod 1.
It is designed to prevent smoke ash and the like from entering the wall box 2 by ejecting it into the furnace from the gap between the scrapers 3 and 3.
しかしながら、上述した従来の構造ではシール
エアーが多量に炉内に入るためリークエアー量が
増大して排ガス量が増加するとともに、シールエ
アーによりボイラー水管の低温腐食等をひき起す
という欠点があつた。 However, the conventional structure described above has the disadvantage that a large amount of seal air enters the furnace, increasing the amount of leak air and increasing the amount of exhaust gas, and that the seal air causes low-temperature corrosion of the boiler water tubes.
すなわち、シールエアーが炉内に多量に導入さ
れると高温帯の火炉部において、SO2濃度の高い
排ガスと接しSO2ガスの一部がSO3に酸化転化す

却され、排ガス中に含まれているSO3とシール部
周辺で発生したSO3が露点以下に冷却され硫酸と
なり、シール部周辺の低温腐食をひき起すことに
なるものである。 That is, when a large amount of seal air is introduced into the furnace, it comes into contact with exhaust gas having a high SO 2 concentration in the high-temperature furnace section, and a portion of the SO 2 gas is oxidized and converted to SO 3 . The area around the seal is then cooled by the seal air, and the SO 3 contained in the exhaust gas and the SO 3 generated around the seal are cooled below the dew point and become sulfuric acid, causing low-temperature corrosion around the seal. It is something.
そこで、シールエアーを停止した状態で操業す

ワーロツドの作動を困難にするものである。また
上記クリンカーが付着した場合その掃除除去も極
めて困難になる等の欠点があつた。 Therefore, if the operation is carried out with the seal air stopped, the high temperature semi-molten smoke ash will enter the inside of the wall box and become slowly cooled and hardened clinker after long periods of use, causing the suit blower rod to This makes it difficult to operate. Further, if the clinker adheres, it is extremely difficult to clean and remove it.

スーツブロワーウオールボツクスを提供するもの
である。 This idea was made to solve the above-mentioned drawbacks of the conventional structure.As a result of research on the properties of smoke ash in the furnace section, which is the high temperature zone of the boiler, the inventor found that the ash was rapidly cooled before it accumulated and fused. It was discovered that the smoke ash would remain in powder form and would not stick. Focusing on this point, an air cooling box was installed in the seal part of the furnace to rapidly cool the smoke ash that had entered and leave it in powder form outside. The present invention provides a suit blower wall box configured to discharge water.

系外へ排出される。 Hereinafter, one embodiment of this invention will be explained in detail based on FIGS. 2 and 3. In the figure, 1 is a suit blower rod. The suit blower rod 1 is slidably assembled in an air cooling box 10 attached to the main body 5.
The air cooling box 10 is provided with an inlet 11 and an outlet 12 through which high-pressure cooling air is introduced. Therefore, the cooling fluid introduced into the box 10 is discharged from the outlet 12 to the outside of the system without being introduced into the furnace.

ー内に除去される。 In the air-cooled box 10 configured as described above, the suit blower rod 1 and the air-cooled box 10 are
Smoke ash enters through the gap between the air cooling box 10 and the soot blower rod 1, but the smoke ash is rapidly cooled between the air cooling box 10 and the soot blower rod 1 and forms a sealing film 13, thereby providing a seal with the outside air. Moreover, since this smoke ash is in the form of a smooth powder, the suit blower rod 1
It does not interfere with the sliding of the air cooling box 10, and only when you want to remove smoke and ash, use a separate air hose 14 to connect the air cooling box 10.
By injecting high-pressure cleaning air toward the boiler through the gap between the rod 1 and the rod 1, it can be easily removed into the boiler.

で、大気によるリークエアがボイラー内に侵入す
ることはほとんどなく、侵入することがあつても
極く微量であるから支障になることはない。 That is, normally, the draft inside the boiler is under negative pressure, so when the suit blower is used, the surrounding area instantly becomes positive pressure, and the smoke ash enters through the gap between the suit blower rod 1 and the air cooling box 10, and the smoke ash itself Since the boiler is sealed with air, there is almost no chance that air leaking from the atmosphere will enter the boiler, and even if it does, the amount will be so small that it will not cause any problems.
また、空冷ボツクス１０とロツド１との隙間に

ている。 In addition, since the smoke that has entered the gap between the air cooling box 10 and the rod 1 is in powder form, it does not interfere with the sliding of the suit blower rod 1, and when cleaning, it is necessary to use high-pressure cleaning air from the air hose 14. can be introduced into the gap between the air cooling box 10 and the rod 1 and discharged into the boiler.
なお、一層急冷が必要である場合は水冷にする
ことも可能である。 In addition, if even more rapid cooling is required, it is also possible to use water cooling.

ボイラー内へ排出するものである。 As explained in detail above, the suit blower wall box according to this invention has a cooling box attached to the main body so as to surround a sliding suit blower rod, and a cooling fluid for the box is provided in the box. It has a simple structure in which seal air is introduced from the inlet and discharged from the system through the outlet, and there is no need to constantly inject seal air like in the conventional structure, and the gap between the air cooling box and the suit blower rod is eliminated. The ash is rapidly cooled to form a seal film that maintains a powdered state before it accumulates on the air, and high-pressure cleaning air is used to remove the ash that has entered the gap between the air-cooled box and the suit blower rod. is injected into the above-mentioned gap and discharged into the boiler.
従つて、シールエアーが多量にボイラー内に入

す等の欠点が解決される等実用上の効果を奏す
る。 Therefore, a large amount of seal air does not enter the boiler, and practical effects such as solving problems such as low-temperature corrosion around the seal portion are achieved.
