Description

本発明は生石灰と水との反応を調整する反応調整剤、及びその調整剤を使用した反応を利用した有機廃棄物の処理方法に関し、特に、動植物残渣、(脱水)汚泥、ろ過残渣、廃切削油、洗浄廃液のような、水分の多い動植物性有機物を、環境汚染の心配なしに、単純な設備で短時間に処理できる方法、及びこの処理方法を利用した有機ハロゲン化物などの、動植物に有害な元素を含有する乾燥有機物の処理方法に関する。   The present invention relates to a reaction regulator that adjusts the reaction between quicklime and water, and a method for treating organic waste using a reaction using the regulator, and in particular, animal and plant residues, (dehydrated) sludge, filtration residues, waste cutting Harmful to animals and plants, such as oil, washing waste liquids, and other methods that can handle high-moisture animals and plants organic matter in a short time without worrying about environmental pollution, and organic halides that use this treatment method The present invention relates to a method for treating dry organic matter containing various elements.

従来、高水分動植物性有機物については埋立処理、焼却処理、堆肥化処理などが行われており、低水分廃棄物については主として焼却処理が行われている。特に、高含水率廃棄物は、微生物を利用した生ごみ処理機以外に適切な処理設備がないため、焼却処理又は乾燥後堆肥化処理が主流であるが、いずれも大規模な装置を必要としており、また、設備の設置に関する諸手続が煩雑である上時間を要するので、高含水有機物発生事業所でそれを処理することは困難である。そこで多くの高含水有機物排出事業者は、外部にそれを廃棄物として処理することを依頼せざるを得ない場合が多く、ゼロエミッションを目指す事業所にとっては大きな課題となっている。   Conventionally, landfill processing, incineration processing, composting processing, and the like have been performed on high-moisture animal and plant organic matter, and incineration processing has been mainly performed on low-moisture waste. In particular, waste with high water content is mainly incinerated or composted after drying because there is no appropriate treatment facility other than garbage processing machines using microorganisms, but both require large-scale equipment. In addition, since various procedures related to installation of equipment are complicated and time consuming, it is difficult to process it at a high water content organic matter generating establishment. Therefore, many companies with high water content organic matter discharges often have to ask outside to dispose of them as waste, which is a major issue for establishments aiming for zero emissions.

また上記処理の内、環境汚染を引き起こしにくい堆肥化処理方法の一つとして、生石灰を添加し、攪拌して有機物を乾燥させる方法が知られている。この場合、生石灰の水和反応熱によって短時間で反応系の温度が急上昇し、100℃に達すると沸騰状態となって水蒸気及び消石灰粉末が噴出するので、バグフィルター等の噴出ガス防止装置を設けることを余儀なくされたり、生石灰の投入を徐々に行うか生石灰の表面を油剤等で被覆しなければならず、作業性が悪かったりコスト高となるなどの欠点があった。また、水蒸気により反応熱が奪われる割合が多いため、反応系上部の温度は105℃を超えず、底部の温度も200℃を超えることはないので、有機物の処理速度等が十分ではないという欠点があった。   As one of the composting methods that hardly cause environmental pollution among the above-mentioned treatments, there is known a method of adding quick lime and stirring to dry organic matter. In this case, the temperature of the reaction system rapidly rises in a short time due to the heat of hydration reaction of quicklime, and when it reaches 100 ° C., it becomes a boiling state, and water vapor and slaked lime powder are ejected. However, there is a drawback that the quick lime is gradually added or the surface of the quick lime has to be coated with an oil or the like, resulting in poor workability and high cost. Moreover, since the reaction heat is often taken away by water vapor, the temperature at the top of the reaction system does not exceed 105 ° C., and the temperature at the bottom does not exceed 200 ° C., so that the processing rate of organic matter is not sufficient. was there.

係る欠点は、酸化カルシウムとケイ酸ナトリウムを主成分とする処理剤を使用することによって改善されたが、この場合には、別途脱臭装置を必要としたり、アンモニアイオンの吸収剤等を別途添加したりする上、実質的には生石灰の表面を油脂で被覆することが必要であるなど、反応系が複雑になるという欠点があった(例えば特許文献1〜4)。   These disadvantages have been improved by using a treatment mainly composed of calcium oxide and sodium silicate. In this case, however, a separate deodorizing device is required, or an ammonia ion absorbent is added separately. In addition, there is a drawback that the reaction system becomes complicated, for example, it is necessary to substantially coat the surface of quicklime with fats and oils (for example, Patent Documents 1 to 4).

本発明者らは上記の欠点を解決すべく鋭意検討した結果、水溶性有機物と水、及び必要に応じて更に水溶性無機物を含有する混合物が、生石灰と水との反応を極めて効果的に抑制することができること、それにもかかわらず、この反応調整剤を添加した高含水有機物に生石灰を添加した場合には、生石灰の水和反応熱と有機物の分解反応熱の相乗作用により、反応系を沸騰させること無く、その内部温度を580℃程度にまで上げることが可能であることを見出し本発明に到達した。   As a result of intensive studies to solve the above-mentioned drawbacks, the present inventors have found that a mixture containing a water-soluble organic substance and water and, if necessary, further a water-soluble inorganic substance, extremely effectively suppresses the reaction between quick lime and water. Nevertheless, when quick lime is added to a highly water-containing organic substance to which this reaction modifier is added, the reaction system boils due to the synergistic effect of the heat of hydration reaction of quick lime and the heat of decomposition reaction of organic matter. The inventors have found that the internal temperature can be increased to about 580 ° C. without causing the present invention to arrive at the present invention.

従って、本発明の第1の目的は、生石灰と水との反応を効率良く調整することのできる生石灰反応調整剤を提供することにある。

The above-mentioned objects of the present invention are a reaction regulator having a function of regulating an exothermic reaction with quicklime and water, wherein the reaction regulator is a mixture of 10% by weight or more of a water-soluble organic substance and 90% by weight or less of water.

In this case, if a harmful substance such as a halogenated hydrocarbon is introduced into a slaked lime bath having an internal temperature of 300 ° C. or higher, the harmful substance can be treated without causing environmental destruction.

本発明の反応調整剤は、極めて単純であるにもかかわらず、反応系に後から生石灰を短時間で速やかに添加しても、生石灰と水の反応を効率よく抑制する事ができるので、高含水有機廃棄物の生石灰処理に特に適している。また本発明の含水有機物の処理方法は、周辺環境を汚染することなく、高含水有機廃棄物を迅速且つ経済的に処理し、同時に、高品質で製品価値の高い有機質消石灰又は無機質消石灰を製造することができる。更に、簡単な装置で処理する事もできるので装置のコンパクト化が可能であり、車両等に装置を設置して、運搬性、作業性、操作性に優れた処理装置とすることもできる。   Although the reaction modifier of the present invention is very simple, the reaction system can efficiently inhibit the reaction of quick lime and water even if quick lime is quickly added to the reaction system later. It is particularly suitable for quick lime treatment of hydrous organic waste. In addition, the method for treating hydrous organic matter of the present invention treats highly hydrous organic waste quickly and economically without polluting the surrounding environment, and at the same time, produces high-quality organic slaked lime or inorganic slaked lime. be able to. Furthermore, since processing can be performed with a simple apparatus, the apparatus can be made compact, and the apparatus can be installed in a vehicle or the like to provide a processing apparatus having excellent transportability, workability, and operability.

本発明の反応調整剤で使用する水溶性有機物は、ケトン類、グリコールエーテル等の水溶性エーテル類、カルボン酸類、メタノールやエタノールはもとより、グリセリン等の多価アルコールやアミノアルコールを含むアルコール類、アミン類、アミノ酸類、界面活性剤及び糖類の中から適宜選択することができる。これらは単独で使用しても2種以上を混合して用いても良い。また、水溶性有機物の濃度は特に限定されるものではなく、使用状況に応じて適宜設定する事ができる。例えば、処理対象となる有機物の含水量が高ければ水溶性有機物の濃度が100%に近くても良いし、有機物の含水量が低ければ、反応調整剤中の水溶性有機物の濃度が10%以下でも良い。添加作業性の上からは、15〜70%程度である事が好ましい。また、界面活性剤は、非イオン系界面活性剤、アニオン系界面活性剤、カチオン系界面活性剤の何れであっても良い。   Water-soluble organic substances used in the reaction modifier of the present invention include water-soluble ethers such as ketones and glycol ethers, carboxylic acids, methanol and ethanol, polyhydric alcohols such as glycerin and alcohols containing amino alcohol, amines Can be appropriately selected from among amino acids, amino acids, surfactants and saccharides. These may be used alone or in combination of two or more. In addition, the concentration of the water-soluble organic substance is not particularly limited, and can be appropriately set according to the use situation. For example, if the water content of the organic substance to be treated is high, the concentration of the water-soluble organic substance may be close to 100%, and if the water content of the organic substance is low, the concentration of the water-soluble organic substance in the reaction modifier is 10% or less. But it ’s okay. From the viewpoint of workability for addition, it is preferably about 15 to 70%. The surfactant may be any of a nonionic surfactant, an anionic surfactant, and a cationic surfactant.

本発明の反応調整剤で使用する水溶性無機物は、水酸化物、硫酸塩、炭酸塩、ケイ酸塩の中から適宜選択することができる。これらは単独で使用しても2種以上を混合して用いても良い。
また、その添加量には特に制限があるわけではなく、最終生成物である有機質消石灰や無機質消石灰の品質などを考慮して適宜決定する事ができる。

Moreover, there is no restriction | limiting in particular in the addition amount, It can determine suitably considering the quality etc. of organic slaked lime and inorganic slaked lime which are final products.

本発明における高含水有機物とは、排水処理汚泥、動植物残渣、焼酎廃液、処分飲料水等のような、通常は水分が80重量%以上という水分の多い動植物性有機物を包含する概念であるが、必要に応じて適宜ろ過などの手段によって含有される水分を調整しても良い。本発明においては、低含水有機物を使用する事ができないというわけではなく、混合した全体として天然の動植物の含水率よりも高い水分を含有するようにして使用することができる。   The high water content organic matter in the present invention is a concept including a watery animal or plant organic matter usually having a water content of 80% by weight or more, such as wastewater treatment sludge, animal and plant residues, shochu waste liquid, disposal drinking water, etc. You may adjust the water | moisture content contained suitably by means, such as filtration, as needed. In the present invention, it is not impossible to use a low water content organic substance, and it can be used so as to contain water higher than the water content of natural animals and plants as a whole.

本発明の高含水有機物の処理方法及び乾燥有機物の処理方法においては、高含水有機物の種類や含水率を考慮して適宜反応調整剤を使用するが、特に、前記高含水有機物100重量%に対して反応調整剤の使用量が0.1〜20重量部となるように反応調整剤の種類や濃度を調整する事が好ましい。尚、処理費用を低減するために、使用する反応調整剤の使用量を極力抑制する事が好ましい。使用すべき最小の反応調整剤の使用量は、処理される高含水有機物の種類や含水率、及び処理剤中の水溶性有機物や水溶性無機物の種類や濃度等によって異なるが、その量は、種々の反応調整剤を添加した被処理物中に一定量の生石灰を添加し、それぞれの場合の反応開始時間を測定する、などのモデル実験を行う事によって容易に決定する事ができる。   In the method for treating high water content organic matter and the method for treating dry organic matter of the present invention, a reaction modifier is appropriately used in consideration of the type and water content of the high water content organic material. It is preferable to adjust the type and concentration of the reaction modifier so that the amount of the reaction modifier used is 0.1 to 20 parts by weight. In order to reduce the processing cost, it is preferable to suppress the amount of reaction modifier used as much as possible. The amount of the minimum reaction modifier to be used varies depending on the type and moisture content of the high water content organic substance to be treated, and the type and concentration of the water soluble organic substance and water soluble inorganic substance in the treatment agent. It can be easily determined by carrying out a model experiment such as adding a certain amount of quicklime to the workpiece to which various reaction modifiers are added and measuring the reaction start time in each case.

本発明で使用する生石灰は特に限定されるものではなく、特に高い純度が要求されるものでもないが、純度の高い方が反応効率は高くなるので、コストとの兼ね合いで適当なものを使用すれば良い。粒度も反応物を均一にできる限り特に限定される事はなく、粒度分布も特にそろえる必要はない。粉状物、粒状物、礫状物の何れも使用可能であるが、通常工業的に使用する粒状生石灰又は生石灰粉末をそのまま使用する事ができる。その使用量は、含水有機物100重量部に対して30〜300重量部であるが、短時間の内に速やかに投入する。反応内温を300〜580℃にする場合には40〜300重量部とする事が好ましい。反応内温を190℃以下とするか、300〜580℃とするかは、生石灰と水の反応熱とその後の有機物の燃焼反応による発熱量によるので、反応混合物の到達温度は、含水有機物中の水分と使用する生石灰の量比だけではなく、含水有機物に含有される有機物の量や生石灰の投入方法にも依存する。   The quicklime used in the present invention is not particularly limited and is not particularly required to have a high purity. However, the higher the purity, the higher the reaction efficiency. Therefore, use an appropriate one in consideration of cost. It ’s fine. The particle size is not particularly limited as long as the reactants can be made uniform, and the particle size distribution need not be particularly uniform. Any of powder, granular and gravel can be used, but granular quicklime or quicklime powder usually used industrially can be used as it is. The amount of use is 30 to 300 parts by weight with respect to 100 parts by weight of the water-containing organic matter, but it is charged quickly within a short time. When the internal temperature of the reaction is 300 to 580 ° C., it is preferably 40 to 300 parts by weight. Whether the internal temperature of the reaction is 190 ° C. or lower or 300 to 580 ° C. depends on the calorific value of the reaction heat of quicklime and water and the subsequent combustion reaction of the organic matter, so the ultimate temperature of the reaction mixture is It depends not only on the amount ratio of moisture and quicklime to be used, but also on the amount of organic matter contained in the water-containing organic matter and the method of adding quicklime.

本発明の方法においては、肥料として有用な有機質消石灰を得る場合には、生石灰の添加量を、混合後の温度が190℃以下となるように調整し、土壌改質性に優れた無機質消石灰にする場合には、生石灰の添加量を、混合後の温度が300〜580℃となるように調整する。本発明の方法においては、反応系の温度を十分に高くすることができるため、アンモニアやアミン等の発生はほとんど認められず、異臭もしない。   In the method of the present invention, when obtaining organic slaked lime useful as a fertilizer, the amount of quick lime added is adjusted so that the temperature after mixing is 190 ° C. or lower, and inorganic slaked lime with excellent soil reforming properties is obtained. When doing, the addition amount of quicklime is adjusted so that the temperature after mixing may be 300-580 degreeC. In the method of the present invention, since the temperature of the reaction system can be made sufficiently high, the generation of ammonia, amines and the like is hardly observed and there is no off-flavor.

次に、本発明に従って高含水有機物を処理する具体的方法を以下に示す。具体例として攪拌機付きの反応槽を用いた場合について説明するが、本発明はこれに限定されるものではない。
先ず、攪拌機付反応槽に、高含水有機物100重量部に対して反応調整剤が0.1〜10重量部となるように両者を仕込んで攪拌・混合する。次に、生石灰30〜300重量部を加えて攪拌、混合し、略均一となったところで攪拌機を停止する。この場合、生石灰を一気に速やかに加える。反応物表面から水蒸気の蒸散が認められなくなったところで、未反応物が残らないように攪拌機を低速度でゆっくり回して攪拌する。
Next, a specific method for treating a high water content organic substance according to the present invention will be described below. Although the case where the reaction tank with a stirrer is used as a specific example is demonstrated, this invention is not limited to this.
First, in a reaction tank equipped with a stirrer, both of them are charged so that the reaction modifier is 0.1 to 10 parts by weight with respect to 100 parts by weight of the high water content organic substance, and stirred and mixed. Next, 30 to 300 parts by weight of quicklime is added and stirred and mixed. When the mixture becomes substantially uniform, the stirrer is stopped. In this case, quicklime is added quickly at once. When the evaporation of water vapor is no longer observed from the surface of the reaction product, the stirrer is slowly rotated at a low speed so that no unreacted product remains.

本発明の処理方法においては、反応調整剤が存在するために生石灰と水の反応が緩やかとなるので、水蒸気及び消石灰粉末の暴発は起こらず、水蒸気及び同伴消石灰粉末の発生はわずかである。従って、排出ガス対策としてはスクラバーなどの簡便な装置で対応できるので、設備費を従来より安価に抑えることができる。   In the treatment method of the present invention, the reaction between quick lime and water becomes slow due to the presence of the reaction modifier, so that the steam and slaked lime powder do not explode and the generation of steam and entrained slaked lime powder is slight. Therefore, as a countermeasure for exhaust gas, a simple device such as a scrubber can be used, so that the equipment cost can be kept lower than before.

未反応物が無いことを確認して攪拌機を止め、反応系を冷却した後、反応により生成した有機質消石灰又は無機質消石灰を取り出す。反応温度を190℃以下とした場合に得られる有機質消石灰の組成は、消石灰、灰分、難分解性有機物、水分からなる。難分解性有機物はそのまま残るので、肥料成分として利用できる。   After confirming that there is no unreacted substance, the stirrer is stopped, the reaction system is cooled, and then organic slaked lime or inorganic slaked lime produced by the reaction is taken out. The composition of the organic slaked lime obtained when the reaction temperature is 190 ° C. or lower consists of slaked lime, ash, a hardly decomposable organic substance, and moisture. Since the persistent organic matter remains as it is, it can be used as a fertilizer component.

土壌改質剤として有用な無機質消石灰を得る場合には、攪拌機付反応槽に、高含水有機物100重量部に対して反応調整剤が0.1〜10重量部となるように両者を仕込んで攪拌・混合した後、速やかに生石灰40〜300部を加えて適度に攪拌混合し、攪拌機を停止する。反応物表面から水蒸気の蒸散が略認められなくなったら、ゆっくりと断続的に攪拌を続ける。この間に有機物が徐々に酸化分解され、最終的に無機質消石灰を得ることができる。   In order to obtain inorganic slaked lime useful as a soil modifier, both are charged in a reaction tank equipped with a stirrer so that the reaction modifier is 0.1 to 10 parts by weight with respect to 100 parts by weight of the high water content organic matter. -After mixing, quickly add 40-300 parts of quicklime and mix appropriately and stop the stirrer. When the evaporation of water vapor from the reaction product surface is almost not observed, the stirring is continued slowly and intermittently. During this time, the organic matter is gradually oxidatively decomposed, and finally inorganic slaked lime can be obtained.

従来技術では、生石灰と水との反応が速いために水蒸気の発生が多く、水蒸気に反応熱を奪われるので反応系の温度を200℃以上に上げることは不可能であった。これに対して、本発明では、反応調整剤を混合することにより、生石灰の反応速度を抑制することができるため、反応の初期段階における水和反応熱は反応系の昇温に使用され、水の蒸発に使われることが少ない。これによって、反応熱が生石灰反応系に蓄積されて有機物の分解温度に達し、有機物の分解熱が加わるので更に生石灰反応系の温度が上昇する。水蒸気の発生がなくなった時点で、有機物の分解熱によって温度が持続される。   In the prior art, since the reaction between quick lime and water is fast, water vapor is often generated, and the reaction heat is taken away by the water vapor, so it was impossible to raise the temperature of the reaction system to 200 ° C. or higher. In contrast, in the present invention, since the reaction rate of quicklime can be suppressed by mixing a reaction regulator, the heat of hydration reaction in the initial stage of the reaction is used to raise the temperature of the reaction system, It is rarely used for evaporation of water. As a result, the reaction heat is accumulated in the quicklime reaction system and reaches the decomposition temperature of the organic matter, and the decomposition heat of the organic matter is added to further increase the temperature of the quicklime reaction system. When the generation of water vapor ceases, the temperature is maintained by the heat of decomposition of the organic matter.

このような有機物の酸化分解の反応熱によって温度は上昇を続け、400℃を超える。本明細書では、このように350〜580℃に維持された反応系を「消石灰浴」と称する。この「消石灰浴」の温度は、有機物が存在する限り350〜580℃の高温度を維持し続け、有機物がなくなると温度は徐々に低下する。従って、乾燥した有機物(以下「乾燥有機物」という。)や前記した有機質消石灰を消石灰浴に投入すると、投入された有機物が酸化分解されるので、消石灰浴の温度は前記温度に維持され、投入された有機物は灰化処理される。   The temperature continues to rise due to the reaction heat of the oxidative decomposition of organic matter, and exceeds 400 ° C. In this specification, the reaction system maintained at 350 to 580 ° C. is referred to as “slaked lime bath”. The temperature of this “slaked lime bath” continues to maintain a high temperature of 350 to 580 ° C. as long as the organic matter is present, and the temperature gradually decreases when the organic matter is exhausted. Therefore, when the dried organic matter (hereinafter referred to as “dried organic matter”) or the aforementioned organic slaked lime is added to the slaked lime bath, the introduced organic matter is decomposed by oxidation, so that the temperature of the slaked lime bath is maintained at the above temperature. Organic matter is incinerated.

上記乾燥有機物の例としては、塩化ビニル等のハロゲン化炭化水素、ポリハロゲン化有機物、フッ素樹脂、PCB、ダイオキシン、各種農薬等の動植物に有害な元素を含む化合物、及び高耐熱性樹脂等を挙げることができる。例えばハロゲン化炭化水素を投入すると、その灰化処理の工程でハロゲンはハロゲン化カルシウムとして固定されるので、環境汚染を引起すことがない。最終的に得られる無機質消石灰は、消石灰及び灰分からなる。   Examples of the dry organic matter include halogenated hydrocarbons such as vinyl chloride, polyhalogenated organic matter, fluorine resins, PCBs, dioxins, compounds containing elements harmful to animals and plants such as various agricultural chemicals, and high heat resistant resins. be able to. For example, when a halogenated hydrocarbon is introduced, the halogen is fixed as calcium halide in the ashing process, so that environmental pollution does not occur. The finally obtained inorganic slaked lime consists of slaked lime and ash.

The whole amount was quickly added (within 1 minute addition time), and stirring was stopped.
Although the water vapor had evaporated after 1 minute from the addition of quicklime, the water vapor accompanied with the slaked lime powder did not erupt rapidly.

混合物表面の温度は徐々に上昇して2分後には100℃に達した。水蒸気の蒸散量が増え、5分後には装置内温度がピーク温度(145℃)に達し、以降、徐々に温度が下降し、反応の終了したことが確認できた。反応がピークに達したとき、30rpmの速度で攪拌を再開し、反応を均一化した。
反応終了後、生成した白いサラサラの有機質消石灰を反応装置から消石灰バッグに移送し、貯留した。有機質消石灰の生成量は190部であった。
