本発明の実施形態の石炭灰の造粒物製造設備を示す図である。It is a figure which shows the granulated material manufacture equipment of the coal ash of embodiment of this invention.

以下、本発明の実施形態について説明する。
図１は本発明の実施形態の石炭灰の造粒物製造設備１を示す図である。
実施形態の造粒物製造設備１は、石炭灰から砂程度の粒径（〜４０ｍｍ）を製造するため、石炭灰、固化材（セメント）、水、リターン材を含む添加材を混合機１０で混合し、混合物を造粒機４０へ移送し最大４０ｍｍ程度に造粒する設備である。 Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a diagram showing a coal ash granule manufacturing facility 1 according to an embodiment of the present invention.
The granulated product production facility 1 according to the embodiment uses a mixer 10 to add coal ash, a solidified material (cement), water, and an additive material including a return material in order to produce a particle size (˜40 mm) similar to sand from coal ash. It is a facility that mixes, transfers the mixture to the granulator 40 and granulates it to a maximum of about 40 mm.

石炭灰造粒物の原料は、石炭灰（フライアッシュ、クリンカアッシュを含む）を主原料とし、固化剤として少量のセメント、水、およびリターン材を含む添加材を加えたものである。フライアッシュとは、燃焼ガスとともに吹き上げられるレベルの球状の微粒子で、電気集塵機などで回収される。成分はＳｉＯ２，Ａｌ２Ｏ３，Ｆｅ２Ｏ３，ＣａＯを含む。粒度は０．１ｍｍ以下が９０％である。 The raw material of the coal ash granule is obtained by adding coal ash (including fly ash and clinker ash) as a main raw material and adding a small amount of cement, water, and an additive material including a return material as a solidifying agent. Fly ash is a spherical fine particle that is blown up with combustion gas, and is collected by an electric dust collector or the like. Component comprises SiO 2, Al2O 3, Fe 2 O 3, CaO. The particle size is 90% when 0.1 mm or less.

石炭灰造粒物の造粒物製造設備１は、原料を混合する混合機１０と、混合機１０により混合された原料を一時的に貯蔵して一定量を流出する第１ホッパー２０と、第１ホッパー２０から流出される原料を一定の流量で連続運搬する定量供給機３０と、定量供給機３０から一定の流量で連続運搬される原料を造粒する造粒機４０と、造粒機４０により造粒された造粒物を運搬するコンベア５０と、を備える。
造粒物製造設備１は、さらに、上下左右するコンベア５０により運搬された造粒物を貯蔵する初期養生設備６０と、養生によって互いに付着した造粒物を分解する振動フィーダ８０と、粒度別に分類するふるい機１００とを備える。 The coal ash granulated granule manufacturing facility 1 includes a mixer 10 that mixes raw materials, a first hopper 20 that temporarily stores the raw materials mixed by the mixer 10 and flows out a predetermined amount, 1 A fixed quantity feeder 30 that continuously conveys the raw material flowing out from the hopper 20 at a constant flow rate, a granulator 40 that granulates the raw material continuously conveyed at a constant flow rate from the quantitative supply machine 30, and a granulator 40 And a conveyor 50 that conveys the granulated product that has been granulated.
The granulated product production facility 1 is further classified according to the particle size by an initial curing facility 60 that stores the granulated material conveyed by the conveyor 50 that moves up and down, left and right, a vibratory feeder 80 that decomposes the granulated material adhered to each other by curing. A sieving machine 100.

混合機１０は、所定量に計量された各原料が流入される容器１１と、容器１１内部に配置され、回転軸を中心として回転する撹拌羽根１２と、を備える。
容器１１の上部より、原料として石炭灰、固化材、水、および添加材が流入される。原料は、回転する撹拌羽根１２によって混合される。混合された材料は、容器１１の下部に設けられた流出口より、下部に配置された第１ホッパー２０内に流出される。
このように造粒前に混合機１０を用いて原料を混合するため、造粒工程において石炭灰、固化剤、水、および転化材を含む原料を、確実に混合することができる。 The mixer 10 includes a container 11 into which each raw material weighed in a predetermined amount flows, and a stirring blade 12 that is disposed inside the container 11 and rotates about a rotation axis.
From the upper part of the container 11, coal ash, a solidifying material, water, and an additive are introduced as raw materials. The raw materials are mixed by a rotating stirring blade 12. The mixed material flows out from the outlet provided in the lower part of the container 11 into the first hopper 20 disposed in the lower part.
Thus, since the raw material is mixed using the mixer 10 before granulation, the raw material containing coal ash, a solidifying agent, water, and a conversion material can be reliably mixed in the granulation step.

混合機１０によって混合された原料は、第１ホッパー２０内に流入される。第１ホッパー２０は、容器断面が円錐状または角錐状に形成され、流出口に向かって減少している容器である。
第１ホッパー２０は、混合された原料を一旦貯蔵し、流出口より定量供給機３０に対して定量的に供給する。 The raw material mixed by the mixer 10 flows into the first hopper 20. The first hopper 20 is a container whose container cross section is formed in a conical shape or a pyramid shape and decreases toward the outlet.
The first hopper 20 temporarily stores the mixed raw material, and quantitatively supplies the mixed raw material to the quantitative feeder 30 from the outlet.

定量供給機３０は、モータで回転駆動される、らせん状のスクリューフィーダ３１を備える。混合された原料は一定の流量で、次工程の造粒機４０に連続して運搬される。定量供給機３０の供給量はスクリューフィーダ３１の回転数とリニアに比例し、供給量の調整が容易に可能である。   The fixed amount feeder 30 includes a helical screw feeder 31 that is rotationally driven by a motor. The mixed raw material is continuously conveyed to the granulator 40 of the next process at a constant flow rate. The supply amount of the metering feeder 30 is linearly proportional to the rotational speed of the screw feeder 31 and the supply amount can be easily adjusted.

造粒機４０は、所定角度で傾斜されて回転可能に設けられている円形トレイ状のパン４１と、パン４１を回転させる駆動源（図示せず）と、を備える。
このパン４１に混合材料を投入し、水を加えて加湿させながら回転し、核を成長させて、造粒を行う。 The granulator 40 includes a circular tray-shaped pan 41 that is inclined and rotated at a predetermined angle, and a drive source (not shown) that rotates the pan 41.
The mixed material is put into the pan 41, rotated while adding water and humidified, and a nucleus is grown to perform granulation.

パン４１は、傾斜角度の調整が可能であり、パン４１の傾斜角度や回転速度を変更することにより、造粒される粒子の大きさを調整することができる。
所定の径に造粒された粒子は、遠心力によってパン４１の半径方向の外側に移動する。パン４１の前面は開口している。パン４１の回転中心付近に原料を流入すると、粒径が大きくなるにしたがって造粒物は、遠心力によって外周方向に移動する。そして所定の径になると開口部から外部に放出される。
すなわち、原料を定量供給機３０よって造粒機４０に連続的に流入すると、造粒機４０の外周部から所定径に成長した造粒物が連続的に押し出されていく。
本実施形態で造粒される粒径は最大４０ｍｍ程度であり、天然の砂程度の粒径である。
このように、造粒機４０を連続的に回転することにより、所定径の造粒物が連続的に製造される。 The pan 41 can adjust the tilt angle, and the size of the granulated particles can be adjusted by changing the tilt angle and the rotation speed of the pan 41.
The particles granulated to a predetermined diameter move to the outside in the radial direction of the pan 41 by centrifugal force. The front surface of the pan 41 is open. When the raw material flows into the vicinity of the rotation center of the pan 41, the granulated material moves in the outer peripheral direction by centrifugal force as the particle size increases. And if it becomes a predetermined diameter, it will discharge | release outside from an opening part.
That is, when the raw material is continuously flowed into the granulator 40 by the fixed amount feeder 30, the granulated material that has grown to a predetermined diameter is continuously pushed out from the outer peripheral portion of the granulator 40.
The particle size granulated in the present embodiment is about 40 mm at the maximum and is about the size of natural sand.
Thus, the granulated material of a predetermined diameter is continuously manufactured by rotating the granulator 40 continuously.

造粒機４０において所定径（実施形態では４０ｍｍ）に成長して外部に飛び出した造粒物は、コンベア５０によって運搬される。なお、造粒機４０より飛び出した造粒物を確実に収集してコンベア５０上に乗せるために、造粒機４０の開口部を覆うフードを設け、フードによって捕獲された造粒物をコンベア５０上に流すようにしてもよい。
コンベア５０は、連続的に稼働しており、造粒物は、連続可動するコンベア５０で初期養生設備６０へ移送される。 The granulated material that has grown to a predetermined diameter (40 mm in the embodiment) and jumped to the outside in the granulator 40 is conveyed by the conveyor 50. In addition, in order to collect the granulated material which jumped out from the granulator 40 reliably, and to place it on the conveyor 50, the hood which covers the opening part of the granulator 40 is provided, and the granulated material captured by the hood is conveyed to the conveyor 50. You may make it flow upward.
The conveyor 50 is operating continuously, and the granulated material is transferred to the initial curing equipment 60 by the conveyor 50 that is continuously movable.

このように、本実施形態において、定量供給機３０、造粒機４０、およびコンベア５０が、連続的に稼働している。すなわち、定量供給機３０に原料が連続して流入されると、定量供給機３０、造粒機４０およびコンベア５０は連続的に稼働しているため、造粒物は連続的に製造されて放出される。   Thus, in this embodiment, the fixed amount feeder 30, the granulator 40, and the conveyor 50 are operating continuously. That is, when the raw material is continuously flowed into the metering feeder 30, since the metering feeder 30, the granulator 40 and the conveyor 50 are continuously operated, the granulated material is continuously produced and discharged. Is done.

コンベア５０は連続的に造粒される造粒物を、初期養生設備６０に運搬する。
初期養生設備６０において、造粒物は堆積される。この際、コンベア５０によって運ばれてきた造粒物は、水分を含んでおり、柔軟である。したがって、コンベア５０の端部が高いところに位置して造粒物が長い距離落下すると、造粒物が砕ける場合がある。
このため、本実施形態において、コンベア５０の端部は上下動可能である。そして、造粒物の落下距離が短くなるように、堆積された造粒物の高さに応じて上下する。このようにコンベア５０の端部が造粒物の高さに応じて上下するので、造粒物が砕ける可能性が低減される。
このコンベア５０の端部の上下動は、手動であってもよいが、センサー等を設けて、堆積された造粒物の高さを検知して、自動的に上下動するようにしてもよい。
さらに、養生設備の収容量も限界がある。したがって、第１の初期養生設備６０の収容量が満杯になったときに、コンベア５０の端部は、別の養生設備へと運搬先が変更可能なように、水平方向に可動であってもよい。 The conveyor 50 conveys the granulated material continuously granulated to the initial curing equipment 60.
In the initial curing facility 60, the granulated material is deposited. At this time, the granulated product carried by the conveyor 50 contains moisture and is flexible. Therefore, when the end of the conveyor 50 is located at a high position and the granulated product falls for a long distance, the granulated product may be crushed.
For this reason, in this embodiment, the edge part of the conveyor 50 can be moved up and down. And it goes up and down according to the height of the granulated material deposited so that the fall distance of the granulated material may become short. Thus, since the edge part of the conveyor 50 goes up and down according to the height of a granulated material, possibility that a granulated material will be crushed is reduced.
The vertical movement of the end of the conveyor 50 may be manual, but a sensor or the like may be provided to detect the height of the accumulated granulated material and automatically move up and down. .
Furthermore, the capacity of the curing equipment is limited. Therefore, even if the end of the conveyor 50 is movable in the horizontal direction so that the transport destination can be changed to another curing facility when the capacity of the first initial curing facility 60 is full. Good.

初期養生設備６０で所定の日数（数週間〜１カ月程度）を置いた造粒物は、それぞれが付着・固化（岩おこし）の状態となっている。このため、次に説明する工程で最終の粒度調整を行う。   Each of the granulated materials placed for a predetermined number of days (several weeks to about one month) in the initial curing equipment 60 is in a state of adhesion and solidification (rock formation). For this reason, final particle size adjustment is performed in the process described below.

初期養生設備６０において養生された造粒物は、第２ホッパー７０を経て、振動フィーダ８０に運搬される。振動フィーダ８０は、水平または傾斜したトラフに、機械的に上下運動の加わった振動を与え、粒子を斜め前方に投出すようにして粉粒体を移動、供給するものである。
この振動フィーダ８０において、初期養生設備６０において複数個が付着して塊となった造粒物は分解される。
そして、ここで、４０ｍｍ以下と４０ｍｍより大きいものに仕分けされる。４０ｍｍより大きいものは粉砕機１１０に運搬されて粉砕される。粉砕された造粒物は、再度、第２ホッパー７０に流入され、振動フィーダ８０によって分解される。 The granulated material cured in the initial curing facility 60 is transported to the vibration feeder 80 via the second hopper 70. The vibration feeder 80 applies vibrations that are mechanically subjected to vertical movement to a horizontal or inclined trough, and moves and supplies the powder particles so as to throw the particles obliquely forward.
In the vibration feeder 80, the granulated material that has become a lump in the initial curing equipment 60 is decomposed.
And here, it sorts into the thing below 40 mm and larger than 40 mm. Those larger than 40 mm are transported to the pulverizer 110 and pulverized. The pulverized granulated product flows again into the second hopper 70 and is decomposed by the vibration feeder 80.

４０ｍｍ以下の造粒物は、コンベア９０によって運ばれて、多段式のふるい機１００に流入される。
ふるい機１００では、４０ｍｍ、２０ｍｍ、５ｍｍ、１ｍｍおよび粉末のものに分級される。
そして、用途に応じて適切な粒径のものが出荷される。 A granulated product of 40 mm or less is conveyed by the conveyor 90 and flows into the multistage sieve machine 100.
In the sieving machine 100, it is classified into 40 mm, 20 mm, 5 mm, 1 mm and powder.
And the thing of a suitable particle size is shipped according to a use.

以上、本実施形態によると、以下の効果を有する。
（１）本実施形態によると、石炭灰の造粒物の造粒工程が連続的であるので、処理量が増加する。
（２）本実施形態は、混合工程と、造粒工程とが分離しているので、品質管理が確実にできる。
（３）ふるい機１００における分級で、製品として満たない粒径であった未完成品を、添加材設備に入れることで、原料として再利用でき、不用品発生減による産業廃棄物処理を減少することができる。
（４）さらに、石炭灰の造粒物は、天然砂よりも軽量であり、転動造粒を行うことで、粒の内部に微細な空隙が保有される。この微細な空隙によって、多孔質となり、気孔率および吸水率が高い値を示す。
閉鎖性が高い港湾においては様々な物質が流入、集積、滞留しやすく、底質にヘドロが厚く堆積し、貧酸素水塊の発生による水質や底質の悪化が見られる。このような港湾に本実施形態の石炭灰の造粒物を散布することにより以下の効果を有する。
石炭灰の弱アルカリにより長期バクテリア分解が可能である。また、貧酸素、富栄養の主要因となる硫化水素を吸着し、無害化することができる。空隙へ有機物をトラップして圧密抑制が可能で減容化することができる。軽量で沈降速度が遅いため、浮泥上にカバーリングが可能である。さらに、海藻、藻類が着生し、水産資源回復等の生物生息環境を提供することができる。 As described above, this embodiment has the following effects.
(1) According to this embodiment, since the granulation process of the granulated product of coal ash is continuous, the throughput increases.
(2) In this embodiment, since the mixing step and the granulation step are separated, quality control can be ensured.
(3) By placing an unfinished product with a particle size less than the product in the classification in the sieve machine 100 into an additive material facility, it can be reused as a raw material, thereby reducing industrial waste processing due to the reduction of waste generation be able to.
(4) Further, the granulated product of coal ash is lighter than natural sand, and by performing rolling granulation, fine voids are retained inside the granule. Due to the fine voids, it becomes porous and exhibits high values of porosity and water absorption.
In highly closed ports, various substances tend to flow in, accumulate, and stay, thick deposits accumulate in the bottom sediment, and deterioration of water quality and bottom sediment due to the generation of anoxic water mass is observed. By spraying the coal ash granulated material of the present embodiment to such a harbor, the following effects are obtained.
Long-term bacterial degradation is possible due to weak alkali in coal ash. Moreover, it can adsorb and detoxify hydrogen sulfide, which is a major factor in anoxia and eutrophication. It is possible to trap the organic matter in the gap and suppress the consolidation, thereby reducing the volume. Because it is lightweight and has a slow sedimentation speed, it can be covered on the mud. Furthermore, seaweeds and algae can be established to provide a biological habitat environment such as recovery of marine resources.
