本考案は、セメント原料粉などの粉体を造粒する噴流層造粒炉、詳しくは、造 粒効果を損なうことなく、容易にスケールアップをすることができる噴流層造粒 炉に関するものである。 This invention is a spouted bed granulation furnace for granulating powder such as cement raw material powder. Spouted bed granulation allows for easy scale-up without compromising grain effectiveness. It is related to furnaces.

従来、粉体例えば、セメント原料粉体を造粒してセメントクリンカ（造粒物） を製造する噴流層造粒炉は、図５に示すように、鉛直方向の直胴部１０と、この 直胴部の下部に連設された略逆円錐台部１２と、この略逆円錐台部の下部に連結 された鉛直方向のスロート１４とから構成されている。 そして、投入シュート１６から投入されたセメント原料粉体Ｐ１は、スロート １４からの熱ガスにより略逆円錐台部１２内の空間で噴流層を形成し、浮遊した 状態で滞留し、バーナ１８の燃焼熱により原料粉体の一部が溶融し傾斜面を転動 しつつ造粒され、排出シュート２０から造粒物Ｐ２が排出される（例えば、実開 昭６３−４０７９２号公報、特開昭６３−６０１３８号公報、特開昭６３−１４ ０２８５号公報参照）。なお、２２は噴流層、２４は局部高温域（ホットスポッ ト）、Ｃ１はサイクロンである。 Conventionally, powder such as cement raw material powder was granulated to produce cement clinker (granules). As shown in FIG. 5, the spouted bed granulation furnace for producing the A substantially inverted truncated conical portion 12 connected to the lower part of the straight body portion and connected to the lower part of this substantially inverted truncated conical portion. It is composed of a vertically extending throat 14. Then, the cement raw material powder P1 input from the input chute 16 is fed through the throat. The hot gas from 14 forms a spouted layer in the space inside the substantially inverted truncated cone section 12, and the floating Part of the raw material powder is melted by the combustion heat of the burner 18 and rolled on the slope. The granules P2 are discharged from the discharge chute 20 (for example, during actual production). Publication No. 63-40792, JP-A No. 63-60138, JP-A No. 63-14 (See Publication No. 0285). In addition, 22 is a spouted layer, and 24 is a local high temperature region (hot spot). g), C1 is a cyclone.
【０００３】 また、特開昭５９−１８０２７８号公報には、流動層予備還元炉の炉底部の中 心に同心の中子を設け、流動層部を環状に形成した構成が記載されている。 しかし、この公報記載の流動層予備還元炉は、流動層を環状に形成することに より、分散性のよい炉内均一な流動化を達成し、短い滞留時間で金属酸化物を含 有する粉粒状鉱石を流動層内で予備還元することを目的としており、粉体を噴流 層内で造粒することを目的とする噴流層造粒炉とは、対象を異にしている。0003 In addition, JP-A-59-180278 discloses that the inside of the bottom of a fluidized bed pre-reduction furnace is A configuration is described in which a concentric core is provided at the center and the fluidized bed portion is formed into an annular shape. However, the fluidized bed pre-reduction furnace described in this publication does not allow the fluidized bed to be formed in an annular shape. This makes it possible to achieve uniform fluidization in the furnace with good dispersibility, and to reduce the amount of metal oxides contained in the furnace with a short residence time. The purpose is to pre-reduce powdery ore in a fluidized bed. This is different from a spouted bed granulation furnace, which aims to granulate within a bed.

従来の噴流層造粒炉では、スロートが単孔であるので、スロート内速度が遅く なれば、噴流層が形成されず原料粉体及び造粒物がスロートより直落する。一方 、直落しないようにスロート速度を上げれば、噴流層造粒炉からの飛出し量が多 くなり、造粒炉とサイクロンＣ１との間を循環する。そして、循環量が多量にな れば、燃料使用量が増加し、かつ、循環量が変動（飛出し量の変動）により、シ ステム全体が安定しない。 また、図６に示すように、噴流層２２の層高Ｈ１の単孔型スロートの噴流層造 粒炉を、二点鎖線で示すように、大型化すれば、噴流層を形成するに必要なスロ ート速度を、ますます速くする必要があり、噴流層造粒炉からの飛出しを防ぐた めに炉高を高くする必要がある。また、所望の造粒性能を得るため、噴流層の層 高Ｈ２が高くなり、それにつれて圧力損失も大きくなり、かつ、造粒炉の炉高も 高くなり、きわめて非経済的である。 In conventional spouted bed granulation furnaces, the throat has a single hole, so the speed inside the throat is slow. If this happens, a spouted bed will not be formed and the raw material powder and granules will fall directly from the throat. on the other hand , if the throat speed is increased to avoid direct drop, the amount of ejection from the spouted bed granulation furnace will be large. It circulates between the granulation furnace and the cyclone C1. And the amount of circulation increases. If so, the amount of fuel used will increase, and the circulation amount will fluctuate (fluctuations in the amount of protrusion), causing the system to The entire stem is unstable. In addition, as shown in FIG. As shown by the two-dot chain line, if the size of the grain furnace is increased, the slot required to form a spouted bed can be increased. It is necessary to increase the speed of the granulation process more and more, and to prevent it from flying out of the spouted bed granulation furnace. Therefore, it is necessary to raise the furnace height. In addition, in order to obtain the desired granulation performance, the spouted bed layer is As H2 increases, the pressure loss also increases, and the height of the granulation furnace also increases. It is expensive and extremely uneconomical.
【０００５】 この問題点を解決するために、本考案者らは、図７に示すように、スロート１ ４内に多数の細孔２７を有する多孔部材２６を設けた噴流層造粒炉を既に開発し 、実願平３−１８３２４号として実用新案登録出願している。しかし、図７に示 す噴流層造粒炉をスケールアップし、層高を低く抑えると、（略逆円錐台部１２ の斜面の長さ）／（炉内径）の比が減少し、造粒効果が著しく悪くなる。 これを解決するために、従来は、図８に示すように、多数の小略逆円錐台部２ ８を水平方向（平面的に）に設置することも提案されているが、噴流層平面に多 数の心ができ、その結果、斜線で示すようにデッドスペース（フラット部）３０ が生じ、造粒効果が悪くなるという問題点がある。[0005] In order to solve this problem, the inventors of the present invention proposed a throat 1 as shown in FIG. A spouted bed granulation furnace equipped with a porous member 26 having a large number of pores 27 inside the spouted bed granulator has already been developed. , has applied for utility model registration as Utility Model Application No. 3-18324. However, as shown in Fig. If the spouted bed granulation furnace is scaled up and the bed height is kept low, (approximately inverted truncated conical part 12 The ratio of slope length)/(furnace inner diameter) decreases, and the granulation effect deteriorates significantly. In order to solve this problem, conventionally, as shown in FIG. It has also been proposed to install 8 horizontally (planarly), but if The number mind is created, and as a result, a dead space (flat part) 30 is created as shown by the diagonal line. This causes the problem that the granulation effect deteriorates.
【０００６】 本考案は、上記の諸点に鑑みなされたもので、略逆円錐台部内に、コーン部材 又は山型環状部材を同心状に設けることにより、中心を通るいかなる断面をとっ ても同じ形状になるようにして、デッドスペース（フラット部）をなくし、層高 を低くした状態で噴流層を形成させ、造粒効果を損なうことなく、容易にスケー ルアップを図ることができる噴流層造粒炉を提供することを目的とするものであ る。[0006] The present invention was developed in view of the above points, and includes a cone member in a substantially inverted truncated cone portion. Or by providing chevron-shaped annular members concentrically, any cross section passing through the center can be taken. to eliminate dead spaces (flat parts) and increase the layer height. By forming a spouted bed with a low The purpose is to provide a spouted bed granulation furnace that can increase the Ru.

スロート１４に供給された熱ガスは、スロートの多孔部材２６で速度が速めら れる。このため、供給された熱ガスが比較的遅くても、粉体の直落を避けること ができる。スロート１４からの熱ガスは環状に均一に噴出される。 略逆円錐台部１２内にコーン部材３４又は山型環状部材３６を同心に設けるこ とにより、中心を通るいかなる断面をとっても同じ形状の斜面が形成され、原料 粉体の熱間自己造粒に必要な噴流層の挙動を損なわずに、原料粉体は効率よく造 粒される。 The hot gas supplied to the throat 14 is sped up by the porous member 26 of the throat. It will be done. Therefore, even if the hot gas supplied is relatively slow, direct falling of the powder can be avoided. I can do it. The hot gas from the throat 14 is ejected uniformly in an annular shape. A cone member 34 or a chevron-shaped annular member 36 may be provided concentrically within the substantially inverted truncated cone portion 12. Therefore, no matter what cross section you take through the center, a slope with the same shape is formed, and the raw material Raw material powder can be efficiently produced without impairing the spouted bed behavior necessary for hot self-granulation of powder. It is grained.

本考案は上記のように構成されているので、つぎのような効果を奏する。 （１） 略逆円錐台部内に、コーン部材又は山型環状部材を同心状に設けること により、中心を通るいかなる断面をとっても同じ形状になるので、デッドスペー スがなくなり、層高を低くした状態で噴流層を形成させ、造粒効果を損なうこと なく、容易にスケールアップを図ることができる。 （２） 請求項３では、スロートを多孔にしているので、スロート入口の見掛け 上の熱ガス流速を下げても、細孔から噴出される熱ガス流速を、粉粒体が直落し ない範囲とすることができる。そして、噴流層造粒炉を大型化する際に、スロー トの孔数を増すことにより、炉高をそれ程高くすることなく、粉粒体の飛出し量 を規制することができ、全体として噴流速度が低くても粉粒体の直落しない安定 した噴流層を形成することができる。 Since the present invention is configured as described above, it has the following effects. (1) A cone member or a chevron-shaped annular member is provided concentrically within the substantially inverted truncated cone portion. Therefore, any cross section passing through the center will have the same shape, so there is no dead space. This causes the formation of a spouted bed with a low bed height, which impairs the granulation effect. Therefore, it is possible to scale up easily. (2) In claim 3, since the throat is porous, the appearance of the throat entrance is Even if the flow rate of the hot gas above is lowered, the flow rate of the hot gas ejected from the pores will be suppressed by the powder and granules falling directly. There can be no range. When increasing the size of the spouted bed granulation furnace, the slow By increasing the number of holes in the hole, the amount of powder and granules ejected can be reduced without increasing the furnace height. Even if the overall jet velocity is low, the powder and granules will not fall directly. A spouted bed can be formed.
