Description
本発明は、焼酎蒸留廃液の処理物を原料としたＡＬＣ（オートクレーブ養生気泡コンクリート）に関し、詳しくは、焼酎蒸留廃液を、消石灰を主体とする処理物に代え、これを原料として有効利用したＡＬＣに関する。 The present invention relates to an ALC (autoclave curing aerated concrete) using a processed product of shochu distillation waste liquid as a raw material, and more particularly, to an ALC that effectively uses a shochu distilled waste liquid as a raw material instead of a processed product mainly composed of slaked lime. .
焼酎の製造においては、焼酎蒸留粕や焼酎廃液等と呼ばれる焼酎蒸留廃液が発生し、一般に、この焼酎蒸留廃液量は生産量の２倍に達する。しかも、近年の焼酎ブームによって、その発生量は増加傾向にあり、有効な処理が切望されている。しかし、この焼酎蒸留廃液は、臭気が酷いうえに、含水分が高く（９０％〜９７％）、ＢＯＤやＳＳ等の濃度が一般の排水に比べて高く、微細な植物繊維を多量に含むために固液分離が困難な廃液である。 In the production of shochu, shochu distillate waste liquor called shochu distiller, shochu waste liquor, etc. is generated. In general, the amount of shochu distillate waste reaches twice the production volume. Moreover, due to the recent shochu boom, the amount of generation tends to increase, and effective processing is desired. However, this shochu-distilled waste liquid has a severe odor, high moisture content (90% to 97%), high concentration of BOD, SS, etc. compared to general waste water, and contains a large amount of fine plant fibers. It is a waste liquid that is difficult to separate into solid and liquid.
この焼酎蒸留廃液を有用化する方法が従来から試みられており、例えば、焼酎蒸留廃液をそのまま又は堆肥化して肥料化する方法、或いはそのまま飼料化する方法、プラント処理によって濃縮・乾燥した上で飼料化する方法、焼却する方法、嫌気性処理法と活性汚泥法とを組み合わせて排水処理する方法等が知られている（例えば非特許文献１、特許文献１、特許文献２、特許文献３及び特許文献４参照） A method for making this shochu distillation waste liquid useful has been tried in the past. For example, a method of making shochu distillation waste liquid as it is or composting it into a fertilizer, or a method of converting it into a feed, a feed after being concentrated and dried by plant treatment There are known methods such as non-patent literature 1, patent literature 1, patent literature 2, patent literature 3 and patents, for example, a method of wastewater treatment by combining an anaerobic treatment method and an activated sludge method. (Ref. 4)
しかし、焼酎蒸留廃液をそのまま飼料化または肥料化する方法は、悪臭が著しく、夏季に腐敗し易い問題があり、堆肥化して肥料にする場合も同様の問題がある。また飼料化や肥料化したものはその使用量に限界がある。一方、プラント処理による飼料化、焼却処理、嫌気性処理法と活性汚泥法とを組み合わせた排水処理などの方法は、大規模なプラントの建設や維持に費用を要し、中小の焼酎メーカーでは実施し難い。 However, the method of converting shochu distilled liquor into feed or fertilizer as it is has bad odor and is prone to spoilage in summer, and the same problem occurs when composting into fertilizer. Also, the amount of feed and fertilizer used is limited. On the other hand, methods such as feed conversion by plant treatment, incineration treatment, and wastewater treatment that combines the anaerobic treatment method and activated sludge method are expensive to construct and maintain large-scale plants, and are implemented by small and medium-sized shochu manufacturers. It is hard to do.
このため、現状では、乙類焼酎の生産が日本一の鹿児島県において、平成１５年度（醸造年度：７月１日〜翌年６月３０日）に発生した約３３万ｔの焼酎蒸留廃液のうち、少なくとも１０万ｔの焼酎蒸留廃液が海洋投入されている。今までは天然に由来する汚染されていない有機物等と見なされ、「廃棄物その他の物の海洋汚染防止に関する条約」（通称「ロンドン条約」）の例外品目として海洋投入が認められてきたが、規制強化により、近々海洋投入が極めて困難となる法的規制が予定されており、そこで、従来の方法によらない焼酎蒸留廃液の処理方法が熱望されており、その処理物を有効に利用する技術が求められている。
本発明は、焼酎蒸留廃液の処理について、従来の上記問題を解決したものであり、焼酎蒸留廃液を、消石灰を主体とする処理物に代え、これを原料として有効利用したＡＬＣを提供することを目的とする。 The present invention solves the above-mentioned conventional problems for the treatment of shochu distillation waste liquor, and provides an ALC that effectively uses shochu distillate waste liquor as a raw material instead of a treated product mainly composed of slaked lime. Objective.
本発明は、特定の添加剤を焼酎蒸留廃液に添加して生じた処理物を原料とすることによって上記問題を解決した。即ち、本発明は、以下の（１）〜（３）で表すＡＬＣである。
（１）焼酎蒸留廃液に生石灰を添加して生じた処理物を原料としたことを特徴とするＡＬＣ。
（２）焼酎蒸留廃液に生石灰を添加して生じた処理物が、焼酎蒸留廃液１００質量部に対し、生石灰を３０〜３００質量部添加したものである上記(１)に記載するＡＬＣ。
（３）上記処理物が、焼酎蒸留廃液に生石灰を添加することによって、該焼酎蒸留廃液を脱臭し粉末化したものである上記(１)または上記(２)に記載するＡＬＣ。

(1) ALC characterized by using as a raw material a processed product produced by adding quick lime to a shochu distillation waste liquid.
(2) The ALC described in (1) above, wherein the processed product obtained by adding quick lime to the shochu distillation waste liquid is obtained by adding 30 to 300 parts by weight of quick lime to 100 parts by weight of the shochu distillation waste liquid.
(3) The ALC described in (1) or (2) above, wherein the treated product is obtained by deodorizing and powdering the shochu distillation waste liquid by adding quick lime to the shochu distillation waste liquid.
焼酎蒸留廃液は含水率が９０％以上の高含水物であるが、これに生石灰を添加すると、その水和反応の発熱によって水分が蒸発し、また生石灰が消石灰に変化するときに多量の水分を吸収して脱水が進み、水酸化カルシウム（消石灰）を主体とした処理物が得られる。本発明のＡＬＣは、これをカルシウム源として利用したものである。この処理物を原料として用いると、水酸化カルシウムが酸化カルシウムになる温度は約４５０℃であり、炭酸カルシウムが酸化カルシウムになる温度約９００℃に比べてかなり低いので、炭酸カルシウムを用いるよりも製造時の燃料費が少なく、かつ発生するＣＯ２量も少なくできる利点がある。 Shochu distillation waste liquid is a highly water-containing product with a moisture content of 90% or more, but when quick lime is added to it, water evaporates due to the heat generated by the hydration reaction, and a large amount of water is added when quick lime changes to slaked lime. Absorption proceeds and dehydration proceeds, and a processed product mainly composed of calcium hydroxide (slaked lime) is obtained. The ALC of the present invention uses this as a calcium source. When this treated product is used as a raw material, the temperature at which calcium hydroxide becomes calcium oxide is about 450 ° C., which is considerably lower than the temperature at which calcium carbonate becomes calcium oxide at about 900 ° C. There is an advantage that the fuel cost at the time is small and the amount of generated CO 2 can be reduced.
本発明のＡＬＣは、焼酎蒸留廃液の処理物を原料として用いるので、焼酎蒸留廃液の処理物を大量に消費することができる。従って、焼酎蒸留廃液の有用化を推進することができ、焼酎蒸留廃液の大量処理を可能にする。本発明に用いる焼酎蒸留廃液の処理物は焼酎蒸留廃液に生石灰を添加したものであり、その製造には大規模なプラントは必要としないので、この実施には中小の焼酎メーカーでも容易に行うことができる。このため、本発明によれば、焼酎メーカーで発生した大量の焼酎蒸留廃液を有用化することを可能にする。 Since the ALC of the present invention uses a processed product of shochu distillation waste liquid as a raw material, a large amount of the processed product of shochu distilled waste liquid can be consumed. Accordingly, it is possible to promote the usefulness of the shochu distillate waste liquor and to enable mass processing of the shochu distillate waste liquor. The processed product of the shochu distillation waste liquid used in the present invention is obtained by adding quick lime to the shochu distillation waste liquid, and its production does not require a large-scale plant. Can do. For this reason, according to the present invention, it is possible to make a large amount of shochu distillation waste liquid generated by a shochu maker useful.
本発明のＡＬＣは、焼酎蒸留廃液の処理物を原材料として用いるので、成形性が良くなり、製品の収率が高い。 Since the ALC of the present invention uses a processed product of shochu distillation waste liquid as a raw material, the moldability is improved and the product yield is high.
以下、本発明を実施例と共に具体的に説明する。
本発明は、焼酎蒸留廃液に生石灰を添加して生じた処理物を原料としたことを特徴とするＡＬＣであり、好ましくは、焼酎蒸留廃液に生石灰を添加して生じた処理物が、焼酎蒸留廃液１００質量部に対し、生石灰を３０〜３００質量部添加した処理物を原料としたＡＬＣである。
Hereinafter, the present invention will be specifically described with examples.
The present invention is an ALC characterized by using as a raw material a treatment product produced by adding quick lime to a shochu distillation waste liquor. Preferably, a treatment product produced by adding quick lime to a shochu distillation waste solution is a shochu distillate. It is ALC which used as a raw material the processed material which added 30-300 mass parts of quick lime with respect to 100 mass parts of waste liquids.
本発明のＡＬＣに用いる処理物を製造する焼酎蒸留廃液の種類は限定されない。芋焼酎蒸留廃液、麦焼酎蒸留廃液、米焼酎蒸留廃液、そば焼酎蒸留廃液、黒糖焼酎蒸留廃液、泡盛焼酎蒸留廃液などの各種原料を用いる蒸留廃液について本発明を適用することができる。 The kind of shochu distillation waste liquid which manufactures the processed material used for ALC of this invention is not limited. The present invention can be applied to distillation waste liquids using various raw materials such as waste shochu distillation waste liquid, wheat shochu distillation waste liquid, rice shochu distillation waste liquid, buckwheat shochu distillation waste liquid, brown sugar shochu distillation waste liquid, and Awamori shochu distillation waste liquid.
上記処理物の製造に用いる生石灰は、硬焼生石灰、軟焼生石灰などが挙げられ、酸化カルシウムを主成分とするものであれ生石灰として用いることができる。バッチ式で焼酎蒸留廃液に生石灰を添加する場合、生石灰に硬焼生石灰を用いると、水和反応が比較的緩やかに起こり、処理物の急激な温度上昇が起こり難いので、一バッチ当たりの処理量を多くすることができる。一方、生石灰に中焼生石灰または軟焼生石灰を用いると、水和反応が比較的速やかに起こり、処理時間を短くすることができるので好ましい。 Examples of the quick lime used for the production of the processed product include hard calcined quick lime and soft calcined quick lime, and any calcium lime as a main component can be used as quick lime. When adding quick lime to shochu distillation waste liquid in batch mode, if hard calcined quick lime is used as quick lime, the hydration reaction occurs relatively slowly and the temperature of the processed product is unlikely to rise rapidly. Can be more. On the other hand, it is preferable to use medium calcined lime or soft calcined lime as quick lime because the hydration reaction occurs relatively quickly and the treatment time can be shortened.
上記処理物を製造する装置の種類・大きさ・数並びに処理速度（単位時間当たりの処理量）に応じて、生石灰の焼成度、粒度および生石灰の添加量などを適宜選択すれば良い。また、生石灰の焼成度、粒度および生石灰の添加量などに応じて、処理装置の種類・大きさ・数並びに処理速度を適宜選択しても良い。 What is necessary is just to select suitably the baking degree of a quick lime, a particle size, the addition amount of quick lime, etc. according to the kind, magnitude | size, number of apparatuses which manufacture the said processed material, and a processing speed (processing amount per unit time). In addition, the type, size, number, and processing speed of the processing apparatus may be appropriately selected according to the calcining degree of quicklime, the particle size, the amount of quicklime added, and the like.
生石灰の添加量は、焼酎蒸留廃液１００質量部に対し、生石灰３０〜３００質量部が好ましい。３０質量部未満では焼酎蒸留廃液の水分量が多いために、得られるスラリー濃度が薄く、水分を除去するには更に乾燥工程や設備が必要となる。一方、生石灰添加量が３００質量部を超えると、生石灰の一部が水和反応せずに残り、保管時に保管状況によっては周りから供給される水分によって発熱し、保管容器が熱によって破損する虞がある。 The amount of quicklime added is preferably 30 to 300 parts by weight with respect to 100 parts by weight of the shochu distillation waste liquid. If it is less than 30 parts by mass, the amount of water in the shochu distillation waste liquid is large, so that the resulting slurry concentration is thin, and a drying process and equipment are further required to remove the water. On the other hand, when the amount of quicklime added exceeds 300 parts by mass, a part of the quicklime remains without hydration reaction, and depending on the storage conditions during storage, heat may be generated due to moisture supplied from the surroundings, and the storage container may be damaged by heat. There is.
生石灰の添加量は、好ましくは、焼酎蒸留廃液１００質量部に対し、生石灰５０〜２００質量部である。生石灰を５０質量部以上加えることによって、処理物を粉末化することができるので、処理物の取り扱いが容易となる。また、生石灰の添加量が２００質量部以下であれば、未反応の生石灰が少ない又は無いので、保管時に保管状況によっては周りから供給される水分によって発熱し保管容器が熱によって破損する虞が少ない又は全くない。より好ましい生石灰の添加量は、焼酎蒸留廃液１００質量部に対し、生石灰５０〜１５０質量部である。生石灰の添加量が１５０質量部以下であれば、処理物が適度な付着水分を有するので処理時，輸送時，使用時等において粉塵が発生し難いと伴に、処理設備をより小さくでき、処理物や原材料の保管スペースをより少なくすることができる。 The amount of quicklime added is preferably 50 to 200 parts by weight with respect to 100 parts by weight of the shochu distillation waste liquid. By adding 50 parts by mass or more of quicklime, the processed product can be pulverized, so that the processed product can be easily handled. Also, if the amount of quicklime added is 200 parts by mass or less, there is little or no unreacted quicklime, so there is little risk of heat generation due to moisture supplied from the surroundings during storage and damage of the storage container due to heat. Or not at all. The addition amount of quick lime is more preferably 50 to 150 parts by weight with respect to 100 parts by weight of the shochu distillation waste liquid. If the amount of quicklime added is 150 parts by mass or less, the treated product will have adequate adhering moisture, so that it is difficult for dust to be generated during processing, transportation, use, etc., and the processing equipment can be made smaller. Storage space for things and raw materials can be reduced.
上記処理物を製造する装置は、焼酎蒸留廃液に生石灰を添加できるものであれば良く、形式、大きさなどは限定されない。例えば、連続的に焼酎蒸留廃液に生石灰を所定量添加できる装置を用いても良いし、バッチ式で焼酎蒸留廃液に生石灰を所定量添加できる装置を用いても良い。連続的に焼酎蒸留廃液に生石灰を所定量添加できる装置としては、例えば、連続式コンクリートミキサ、生石灰用ベルトコンベアに所定量の焼酎蒸留廃液を噴霧添加するための噴霧装置を備えた装置、生石灰用輸送管に所定量の焼酎蒸留廃液を噴霧添加するための噴霧装置を備えた装置などが挙げられる。また、バッチ式で焼酎蒸留廃液に生石灰を所定量添加できる装置としては、パン型コンクリートミキサ、パグミル型コンクリートミキサ、重力式コンクリートミキサ、ヘンシェル式ミキサ、リボンミキサ、噴射式ミキサ、トラックアジテータなどが挙げられる。 The apparatus for producing the processed product is not limited as long as it can add quick lime to the shochu distillation waste liquid. For example, an apparatus capable of continuously adding a predetermined amount of quick lime to the shochu distillation waste liquid may be used, or an apparatus capable of adding a predetermined amount of quick lime to the shochu distillation waste liquid in a batch type may be used. As a device that can continuously add a predetermined amount of quick lime to the shochu distillation waste liquid, for example, a continuous concrete mixer, a device equipped with a spray device for spraying and adding a predetermined amount of shochu distillation waste liquid to a quick lime belt conveyor, for quick lime Examples include an apparatus equipped with a spraying device for spraying and adding a predetermined amount of shochu distillation waste liquid to the transport pipe. The batch type equipment that can add a certain amount of quicklime to the shochu distillation waste liquid includes bread type concrete mixer, pug mill type concrete mixer, gravity concrete mixer, Henschel type mixer, ribbon mixer, jet mixer, truck agitator, etc. It is done.
なお、上記製造装置においては、生石灰と焼酎蒸留廃液とが均一に混合されるように、コンクリートミキサなどの混合手段を有する装置が好ましい。また、上記実施装置は、ミキサ、計量器、焼酎蒸留廃液供給用ポンプ、生石灰用ホッパ、および制御盤などをトラック等の車体に載せた移動式の装置としても良い。 In addition, in the said manufacturing apparatus, the apparatus which has mixing means, such as a concrete mixer, is preferable so that quick lime and shochu distillation waste liquid may be mixed uniformly. The implementation device may be a mobile device in which a mixer, a meter, a shochu distillation waste liquid supply pump, a quicklime hopper, a control panel, and the like are mounted on a vehicle body such as a truck.
上記処理物の製造においては、焼酎蒸留廃液に生石灰を添加することによって、焼酎蒸留廃液に９５質量％程度含まれる水分と生石灰が発熱しながら水和反応し、水酸化カルシウム（消石灰）を生じる。このときの発熱によって焼酎蒸留廃液中の水分が蒸発し、また消石灰に水分が取り込まれるので更に水分が減少する。処理物の状態は生石灰の添加量に応じてスラリー状からペースト状になり、生石灰の添加量が増えると粉末状になる。 In the production of the treated product, by adding quick lime to the shochu distillation waste liquor, the moisture and quick lime contained in the shochu distillation waste liquor is about 95% by mass while generating heat to produce calcium hydroxide (slaked lime). The moisture in the shochu distillation waste liquid evaporates due to the heat generated at this time, and the moisture is further taken in because the moisture is taken into the slaked lime. The state of the processed material changes from a slurry to a paste according to the amount of quicklime added, and becomes powdery when the amount of quicklime added increases.
上記処理物は、焼酎蒸留廃液に生石灰を添加したものであり、消石灰を主体とした強アルカリ性の物質であるので、腐敗し難く、長期保存し易い。また、この処理物は脱臭されており、原料である焼酎蒸留廃液の臭気が大幅に除去されているので取り扱い易い。特に、該処理物を粉末状にすることによって取扱性がさらに向上し、また臭気も消石灰と同程度になるので消石灰と同様に取り扱うことができ、より好ましい。 The processed product is obtained by adding quick lime to a shochu distillation waste liquid, and is a strong alkaline substance mainly composed of slaked lime. In addition, this treated product is deodorized and is easy to handle because the odor of the shochu-distilled waste liquid which is a raw material is largely removed. In particular, the handling property is further improved by making the treated product into a powder form, and the odor is almost the same as that of slaked lime.
さらに、上記処理物は、主成分が水酸化カルシウムであるので、カルシウム化合物、特に消石灰、生石灰または炭酸カルシウム（石灰石）の代替原材料として用いることができる。因みに、水酸化カルシウムが酸化カルシウムになる温度は約４５０℃であり、炭酸カルシウムが酸化カルシウムになる温度約９００℃に比べてかなり低いので、上記処理物を炭酸カルシウムの代替原材料として用いると、燃料費が少なく、かつ発生するＣＯ２量も少なくできるので好ましい。 Furthermore, since the main component is calcium hydroxide, the treated product can be used as an alternative raw material for calcium compounds, particularly slaked lime, quicklime or calcium carbonate (limestone). Incidentally, the temperature at which calcium hydroxide becomes calcium oxide is about 450 ° C., and is considerably lower than the temperature at which calcium carbonate becomes calcium oxide, which is about 900 ° C. Therefore, when the above treated product is used as an alternative raw material for calcium carbonate, fuel This is preferable because the cost is low and the amount of generated CO 2 can be reduced.
上記処理物は、主成分が水酸化カルシウムであるので、カルシウム化合物、特に消石灰、生石灰または炭酸カルシウムの代替原材料として用いることができるが、特に上記処理物を本発明のＡＬＣの原材料として用いると、成形性が良くなるので好ましい。 Since the above-mentioned treated product is mainly composed of calcium hydroxide, it can be used as an alternative raw material for calcium compounds, particularly slaked lime, quick lime or calcium carbonate, but particularly when the treated product is used as a raw material for ALC of the present invention, It is preferable because moldability is improved.
本発明のＡＬＣに上記処理物を用いる態様としては、上記焼酎蒸留廃液処理物を、そのまま、加水，乾燥又は／及び粉砕し、或いは化学反応により一部又は全部を他の化合物に変えて、本発明のＡＬＣを製造する。上記焼酎蒸留廃液処理物は主にカルシウム質原料として使用される。上記焼酎蒸留廃液処理物のほかに、必要に応じて、シリカ質原料、アルミナ質原料、酸化鉄原料、アルカリ質原料、硫黄原料、ハロゲン原料、他のカルシウム質原料等を添加しても良い。特に、ケイ酸カルシウム水和物を主要成分とする本発明のＡＬＣを製造する場合は、上記焼酎蒸留廃液処理物に含まれるシリカ質が少ないため、シリカ質原料を原材料として添加することが好ましい。 As an aspect of using the treated product in the ALC of the present invention, the treated product of the shochu-distilled waste liquid is directly added to water, dried or / and pulverized, or partly or entirely changed to another compound by a chemical reaction.

In particular, when the ALC of the present invention containing calcium silicate hydrate as a main component is produced, it is preferable to add a siliceous raw material as a raw material because the amount of siliceous contained in the treated product of the shochu-distilled waste liquid is small.

〔焼酎蒸留廃液処理物の製造〕
直径約１５ｃｍの蒸発皿に焼酎蒸留廃液を５０ｍｌ入れ、攪拌しながら生石灰を所定量添加し、更に３分間スパチュラで混合した。焼酎蒸留廃液は芋焼酎製造時に発生したもの（水分９７質量％、褐色濁液、独特な臭気あり）を用い、生石灰は、軟焼生石灰（粒度：ブレーン比表面積４０００ｃｍ２／ｇ）を用いた。焼酎蒸留廃液に対する生石灰の添加量を変えて試験を行った。生石灰の添加量に応じた処理物の最高温度、処理時の粉塵の発生状況、処理物の性状を表１に示す。
[Manufacturing of shochu distillation waste liquid treatment product]
50 ml of shochu distillation waste liquid was put into an evaporating dish having a diameter of about 15 cm, a predetermined amount of quick lime was added with stirring, and further mixed with a spatula for 3 minutes. The shochu distillation waste liquid used was the one generated during the production of shochu shochu (water content 97% by mass, brown turbid liquid, with a unique odor), and the quick lime was soft calcined lime (particle size: Blaine specific surface area 4000 cm 2 / g). The test was conducted by changing the amount of quicklime added to the shochu distillation waste liquid. Table 1 shows the maximum temperature of the treated product according to the amount of quicklime added, the state of dust generation during the treatment, and the properties of the treated product.
何れの試験水準も、生石灰投入開始から数秒で水蒸気が発生した。投入開始から１〜２分間は激しく水蒸気が発生し、以後は数分にわたり水蒸気が発生し続けたことを目視により確認した。 In all the test levels, water vapor was generated within a few seconds from the start of quick lime charging. It was visually confirmed that water vapor was vigorously generated for 1 to 2 minutes from the start of the charging, and that water vapor was continuously generated for several minutes thereafter.
さらに、各試験水準の処理物について、付着水分量と強熱減量、化学成分および構成鉱物を調べた。この分析結果を表２に示す。付着水分は、混練終了直後の処理物を１０５℃の恒温槽内に２４時間入れ、その前後の質量変化を混練終了直後の処理物の質量で除し、パーセント表示で表したものである。また、構成鉱物は付着水分を１０５℃の恒温槽内で除去したものを粉末Ｘ線回折装置によって分析した。強熱減量（ｉｇ．ｌｏｓｓ）は、１０００℃における値である。また、他の化学成分は、強熱減量を測定した後の処理物を蛍光Ｘ線分析により求めた値である。 Furthermore, the amount of water adhering and the loss on ignition, chemical composition, and constituent minerals were examined for each test level. The analysis results are shown in Table 2. The adhering moisture is expressed as a percentage by putting the treated product immediately after completion of kneading in a thermostat at 105 ° C. for 24 hours, dividing the mass change before and after that by the mass of the treated product immediately after finishing kneading. Further, the constituent minerals obtained by removing adhering moisture in a constant temperature bath at 105 ° C. were analyzed by a powder X-ray diffractometer. The ignition loss (ig.loss) is a value at 1000 ° C. The other chemical components are values obtained by fluorescent X-ray analysis of the processed product after measuring the loss on ignition.
表２に示すように、試験水準No.１〜No.６の何れの処理物も、水酸化カルシウムのピークのみ確認できた。化学成分の測定結果を併せて考慮すると、試験水準No.１〜No.６の処理物の主成分は水酸化カルシウムであることが確認された。試験水準No.７〜No.９の処理物について同様に構成鉱物を分析すると、水酸化カルシウムのピークの他に、酸化カルシウムのピークも確認でき、未反応の生石灰が処理物中に残っていることが確認された。 As shown in Table 2, only the calcium hydroxide peak could be confirmed in any of the processed products of test levels No. 1 to No. 6. Considering the measurement results of the chemical components together, it was confirmed that the main component of the processed products of test levels No. 1 to No. 6 was calcium hydroxide. When the constituent minerals are similarly analyzed for the processed products of test levels No. 7 to No. 9, in addition to the calcium hydroxide peak, a calcium oxide peak can also be confirmed, and unreacted quicklime remains in the processed product. It was confirmed.
表２の結果から、生石灰の添加量は焼酎蒸留廃液１００質量部に対して３０〜３００質量部が適当であり、５０〜２００質量部が好ましいことが分かる。生石灰を３０〜１５０質量部添加した処理物は生石灰の全量が消石灰に変化し、３０質量部添加したものは２４時間後に粉末状になり、５０質量部添加したものは混練直後に粉末状の処理物が得られ、処理時の粉塵の発生も少ない。一方、生石灰を２００質量部以上添加すると、未反応の生石灰が残り、処理時の粉塵が激しく、３００質量部を超えると、処理物の最高温度がかなり高くなる。 From the results of Table 2, it can be seen that the amount of quicklime added is suitably 30 to 300 parts by mass and preferably 50 to 200 parts by mass with respect to 100 parts by mass of the shochu distillation waste liquid. The processed product added with 30 to 150 parts by weight of quick lime changes the total amount of quick lime to slaked lime, the one added with 30 parts by weight becomes powdery after 24 hours, and the one with 50 parts by weight added is treated with powder immediately after kneading. Products are obtained, and the generation of dust during processing is small. On the other hand, when 200 parts by mass or more of quicklime is added, unreacted quicklime remains, and the dust during the treatment is intense. When the amount exceeds 300 parts by mass, the maximum temperature of the processed product becomes considerably high.
［処理物の性状］
１００リットルのパン型モルタル用ミキサに焼酎蒸留廃液を入れ、攪拌しながら生石灰を所定量添加し、更に１５分間混合した。処理物の温度が５０℃程度に下がったところで、当該処理物をフレキシブルコンテナに移し保管した。焼酎蒸留廃液は芋焼酎製造時に発生したもの（水分９７質量％，褐色濁液，独特な臭気あり）を用い、生石灰は軟焼生石灰（粒度：目開き３ｍｍの篩通過品）を用いた。焼酎蒸留廃液に対する生石灰の添加量を変えて試験を行った。生石灰の添加量に応じた処理時の粉塵の発生状況、処理物の性状を表３に示す。
[Properties of processed material]
The shochu-distilled waste liquid was put into a 100-liter pan-type mortar mixer, and a predetermined amount of quick lime was added while stirring, and further mixed for 15 minutes. When the temperature of the processed product dropped to about 50 ° C., the processed product was transferred to a flexible container and stored. The shochu distillation waste liquid used was the one generated during the production of shochu shochu (water content 97 mass%, brown turbid liquid, with a unique odor), and the soft lime was soft calcined lime (particle size: sieved product with 3 mm openings). The test was conducted by changing the amount of quicklime added to the shochu distillation waste liquid. Table 3 shows the state of dust generation during treatment according to the amount of quicklime added and the properties of the treated product.
No.１０〜No.１３の何れの試験水準も、生石灰投入開始から数秒で水蒸気が発生した。投入開始から１〜２分間は激しく水蒸気が発生し、以後は１０数分にわたり水蒸気が発生し続けた。処理時における処理物の最高温度は、何れの水準も１０３℃程度であった。 In any test level of No. 10 to No. 13, water vapor was generated within a few seconds from the start of quicklime input. Water vapor was vigorously generated for 1 to 2 minutes from the start of charging, and water vapor was continuously generated over 10 minutes thereafter. The maximum temperature of the processed material at the time of processing was about 103 ° C. in all levels.
さらに、試験水準No.１０〜No.１３の処理物について、付着水分量と強熱減量、化学成分および構成鉱物を調べた。この分析結果を表４に示す。付着水分は、混練終了直後の処理物を１０５℃の恒温槽内に２４時間入れ、その前後の質量変化を混練終了直後の処理物の質量で除し、パーセント表示で表したものである。また、構成鉱物は付着水分を１０５℃の恒温槽内で除去したものを粉末Ｘ線回折装置によって分析した。強熱減量（ｉｇ．ｌｏｓｓ）は、１０００℃における値である。また、他の化学成分は、強熱減量を測定した後の処理物を蛍光Ｘ線分析により求めた値である。 Furthermore, about the processed material of test level No.10-No.13, the amount of adhering moisture, loss on ignition, a chemical component, and a constituent mineral were investigated. The analysis results are shown in Table 4. The adhering moisture is expressed as a percentage by putting the treated product immediately after completion of kneading in a thermostat at 105 ° C. for 24 hours, dividing the mass change before and after that by the mass of the treated product immediately after finishing kneading. Further, the constituent minerals obtained by removing adhering moisture in a constant temperature bath at 105 ° C. were analyzed by a powder X-ray diffractometer. The ignition loss (ig.loss) is a value at 1000 ° C. The other chemical components are values obtained by fluorescent X-ray analysis of the processed product after measuring the loss on ignition.
表４に示すように、試験水準No.１０〜No.１３の何れの処理物も、水酸化カルシウムのピークのみ確認できた。化学成分の測定結果を併せて考慮すると、この処理物の主成分は水酸化カルシウムであることが確認された。また、処理前の焼酎蒸留廃液に比べて、処理物の臭気はかなり抑えられて取り扱い易くなっており、２週間フレキシブルコンテナで保管した後の処理物の臭気は、市販の消石灰の臭気と略同程度であった。 As shown in Table 4, only the calcium hydroxide peak could be confirmed in any of the processed products of test levels No. 10 to No. 13. Considering the measurement results of the chemical components together, it was confirmed that the main component of this treated product was calcium hydroxide. In addition, the odor of the treated product is considerably suppressed compared with the waste liquor before treatment, and the odor of the treated product after being stored in a flexible container for 2 weeks is almost the same as the odor of commercially available slaked lime. It was about.
〔実施例１：ＡＬＣの製造〕
試験水準No.１０の処理物、普通ポルトランドセメント及びケイ石粉末を用い、これらに水及び気泡剤としてアルミニウム粉末を添加、混合し原料スラリーを製造した。原料スラリーの温度を５５〜６５℃に加熱した上で、鋳型に鋳込んだ。次いで、１８０℃の飽和水蒸気圧下で１０時間オートクレーブ養生を行いＡＬＣを製造した。このときの原料配合及び鋳込温度を、表５に示した。比較として、試験水準No.１０の処理物の代わりに、生石灰を用いた試験水準（試験水準Ｎｏ．１７）も行い、その原料配合及び鋳込温度を、合わせて表５に示した。試験水準Ｎｏ．１４と試験水準Ｎｏ．１７は、同じＣａＯの配合量となる量の、試験水準No.１０の処理物、生石灰をそれぞれ用いた。
[Example 1: Production of ALC]
A processed product of test level No. 10, ordinary Portland cement and silica stone powder were used, and water and aluminum powder were added and mixed as a foaming agent to produce a raw slurry. The temperature of the raw slurry was heated to 55 to 65 ° C. and cast into a mold. Next, autoclaving was performed for 10 hours under a saturated water vapor pressure of 180 ° C. to produce ALC. Table 5 shows the raw material composition and casting temperature at this time. For comparison, a test level (test level No. 17) using quick lime instead of the processed product of test level No. 10 was also performed, and the raw material composition and casting temperature are shown in Table 5 together. Test level No. 14 and test level no. For No. 17, the processed product of test level No. 10 and quicklime were used in the same amount of CaO.
作製した各ＡＬＣの嵩密度及び圧縮強度を表６に示した。嵩密度は、硬化体の質量を硬化体の体積で除して算出した。また、圧縮強度は、ＪＩＳ Ａ ５４１６に従って測定した。得られた試験結果を、表６に示した。 Table 6 shows the bulk density and compressive strength of each ALC produced. The bulk density was calculated by dividing the mass of the cured product by the volume of the cured product. The compressive strength was measured according to JIS A 5416. The test results obtained are shown in Table 6.
本発明の焼酎蒸留廃液処理物を用いたＡＬＣ（試験水準Ｎｏ．１４〜試験水準Ｎｏ．１６）は、該処理物を用いない従来の生石灰を用いたＡＬＣ（試験水準Ｎｏ．１７）と嵩比重、圧縮強度共に遜色のないものであり、ＡＬＣとして好適であることが確認された。 The ALC (test level No. 14 to test level No. 16) using the treated product of the shochu distillation waste liquid of the present invention and the bulk specific gravity of ALC (test level No. 17) using conventional quick lime not using the processed product. The compression strength is comparable, and it was confirmed that it is suitable as ALC.
本発明の焼酎蒸留廃液処理物を用いたＡＬＣは、廃棄物として処分されてきた焼酎蒸留廃液を有効に再利用できるので、より多くの焼酎蒸留廃液を有用化することができる。また、本発明のＡＬＣは、市販の通常のＡＬＣと同様に用いることができる。 Since the ALC using the treated product of the shochu-distilled waste liquid of the present invention can effectively reuse the shochu-distilled waste liquid that has been disposed of as waste, it can make more shochu-distilled waste liquid useful. In addition, the ALC of the present invention can be used in the same manner as commercially available normal ALC.
