Description

本発明は、加熱炉内に廃プラスチック材を投入し、加熱処理により分解処理して再利用を可能とする物質に変換させる廃プラスチック材の分解処理手段についての改良に関する。   The present invention relates to an improvement in a means for decomposing a waste plastic material, which is put into a heating furnace and converted into a material that can be reused by being decomposed by heat treatment.

上述の、廃プラスチック材を加熱処理により分解処理して再利用を可能とする物質に変換させる処理手段は、従前にあっては、廃プラスチック材を、加熱炉内に投入し、フタル酸ナトリウムやステアリン酸ソーダ等の分解促進剤の添加のもとに５００度Ｃ〜８００度Ｃの高温に加熱して、廃プラスチック材の分子構造を分解し溶融させて液化してくる油脂成分に生成し、これを分別精製することで再利用が可能なナフサ等の油脂に変換させ、このとき、生成してくる気化ガスは、廃プラスチック材に混在する塩化ビニールに起因して、その気化ガス中に含まれてくる塩素ガスを、加水により存在させる水蒸気と結合させて塩素水に合成することで捕集分離する処理を行って大気に放出するようにしている。   The processing means for converting the waste plastic material into a material that can be reused by decomposing the waste plastic material by heat treatment has been conventionally used by putting the waste plastic material into a heating furnace and adding sodium phthalate or Heated to a high temperature of 500 ° C. to 800 ° C. under the addition of a decomposition accelerator such as sodium stearate to produce a fat component that decomposes and melts the molecular structure of the waste plastic material, By separating and refining this, it is converted to oil such as naphtha that can be reused. The vaporized gas produced at this time is contained in the vaporized gas due to the vinyl chloride mixed in the waste plastic material. The resulting chlorine gas is combined with water vapor present by hydration and synthesized into chlorine water to collect and separate it and release it to the atmosphere.

この手段は、有害なダイオキシンの発生を抑えるようにはなるが、ダイオキシン発生の起因となる塩素ガスを、添加した水分に結合させて塩素水として捕集し除去するようにしていることで、このとき生成してくる塩酸により設備・機器に腐蝕・損傷が生じてくることから耐酸処理を施さなければならない負担が大きい問題がある。   Although this means suppresses the generation of harmful dioxins, the chlorine gas that causes the generation of dioxins is combined with the added moisture to collect and remove it as chlorine water. Since the hydrochloric acid that is generated sometimes causes corrosion and damage to facilities and equipment, there is a problem that the burden of having to be subjected to acid resistance treatment is large.

また、廃プラスチック材を種類別に選別して、塩素を含む塩化ビニールを取り除いて、塩素を含まない廃プラスチック材だけを加熱炉に投入して、加熱により分解処理する手段が行われている。しかし、この手段は、廃プラスチック材を種類別に選別するのが厄介な問題と、取り除いた塩化ビニールをどのように処理するのか、という問題がある。   In addition, there is a method in which waste plastic materials are sorted by type, vinyl chloride containing chlorine is removed, only waste plastic materials not containing chlorine are put into a heating furnace, and decomposed by heating. However, this means has a problem that it is troublesome to sort waste plastic materials by type, and how to treat the removed vinyl chloride.

また、塩化ビニールが混入している廃プラスチック材を、加熱炉内での熱処理により液化してくる油脂成分と気化ガスとに分解し、その気化ガス中に生じてくる塩素ガスを、添加するナトリウムによりＮａＣｌの形態に固定して、水に溶解させ、塩水として分離除去する手段が、本願の出願人により特開昭２００４−１６８８０６号公報として提起されている。   Also, waste plastic material mixed with vinyl chloride is decomposed into oil and fat components and vaporized gas that are liquefied by heat treatment in the heating furnace, and the chlorine gas generated in the vaporized gas is added to the sodium. A means for fixing in the form of NaCl, dissolving in water, and separating and removing as salt water has been proposed by the applicant of the present application as Japanese Patent Application Laid-Open No. 2004-168806.

この手段には、廃プラスチック材に混入している塩化ビニール材に起因して加熱炉内に発生し油脂成分の気化ガスと共に気化ガス取出管により抽き出されて冷却装置に送り込まれてくる塩素ガスを、塩（ＮａＣｌ）として固定し、それを水に溶解させて塩水にして分離除去するために、気化ガス取出管内に、塩素ガスと結合させるためのナトリウムガスと、結合したＮａＣｌを溶解させるための水とを供給するのがむずかしい問題があり、また、送り込んだナトリウムのガスと塩素との結合および添加した水との結合の効率が悪く、冷却装置の器内に塩素ガスが存在するようになって、それが、冷却装置の器内に設けた受器から液化した油脂成分を取り出すときに器内のガス圧により噴出してくるようになる問題がある。
特開２００４−１６８８０６号公報 This means that chlorine generated in the heating furnace due to the vinyl chloride material mixed in the waste plastic material is extracted by the vaporized gas take-out pipe together with the vaporized gas of the fat and oil component and sent to the cooling device. In order to fix the gas as a salt (NaCl), dissolve it in water and separate and remove it as salt water, the sodium gas to be combined with chlorine gas and the combined NaCl are dissolved in the vaporized gas extraction pipe. In addition, it is difficult to supply water for the purpose, and the efficiency of the combination of the sodium gas and the chlorine that has been fed in and the water that has been added is poor, and the chlorine gas seems to be present in the cooling device. Therefore, there is a problem that when the liquefied oil / fat component is taken out from a receiver provided in the container of the cooling device, it is ejected by the gas pressure in the container.
JP 2004-168806 A

本発明において解決しようとする課題は、廃プラスチック材の分解処理装置の機器を、耐酸性にする負担をなくすために、加熱処理の際に生成してくる塩素ガスを、添加するナトリウムに結合させて塩（ＮａＣｌ）の形態とし、これを添加する水に溶解させて塩水として分離除去する際の、添加するナトリウムに対する塩素ガスの結合および添加する水に対する結合した塩（ＮａＣｌ）の溶解が効率的に行われるようにすることにある。   The problem to be solved in the present invention is to combine chlorine gas generated during heat treatment with sodium to be added in order to eliminate the burden of making the equipment of the waste plastic material decomposition treatment apparatus acid-resistant. In the form of salt (NaCl), when dissolved in water to be added and separated and removed as salt water, the binding of chlorine gas to the added sodium and the dissolution of the bound salt (NaCl) to the added water are efficient. To be done.

上述の課題を解決するための本発明手段は、程々の試験を重ねて得られた知見に基づいて成されたものである。   The means of the present invention for solving the above-described problems has been made on the basis of knowledge obtained through repeated tests.

加熱炉内に塩素ガスとして生成してくる塩素とナトリウムとの結合は、それらが互いに混ざり合っている状態にあることで効率的に行われるようになる。それには、加熱炉内の塩化ビニール材から発生して上昇してくる塩素ガスに対して、ナトリウムのガスが加熱炉内の天井部位に存在していて、これらが混ざり合いながら気化ガス取出管に流れていくようになればよい。そのようにするには、加熱炉内に対し廃プラスチック材を供給するときに、加熱によりナトリウムガスを発生させる水酸化ナトリウム、重炭酸ナトリウム等のナトリウム系の触媒を、廃プラスチック材と合わせて、または別に加熱炉内に供給するようにすればよいこと、そしてこのようにすることで、ナトリウムガスと混ざり合った塩素ガスが、気化ガス取出管を介し冷却装置に流れていくときに、２００度Ｃ程度の温度に降下したところで、塩素がナトリウムを選択してそれに結合するようナトリウムに優先して結合し塩（ＮａＣｌ）となることが判ってきた。さらに、加熱炉内に、供給する廃プラスチック材に対し重量比において１５〜２０％程度の水を供給しておくようにすれば、その水から加熱炉内において発生する水蒸気のガスが気化ガスと共に気化ガス取出管を経て冷却装置の器内に至り冷却器による冷却で水に凝結してくるときに、その凝縮してくる水にナトリウムと塩素とが結合して固定された塩（ＮａＣｌ）が溶解し、塩水となって、凝縮してくる油脂成分を受けるよう冷却装置の器内に設けておくトレーまたは受器の底に、油脂成分と２層に分離して貯留されてくるようになって、その受器の底に設けておく水排水管により取り出せるようになることが判ってきた。   Bonding between chlorine and sodium produced as chlorine gas in the heating furnace is efficiently performed because they are mixed with each other. For this purpose, sodium gas is present in the ceiling part of the heating furnace against the chlorine gas generated and raised from the vinyl chloride material in the heating furnace. It only has to start flowing. To do so, when supplying waste plastic material into the heating furnace, a sodium-based catalyst such as sodium hydroxide or sodium bicarbonate that generates sodium gas by heating is combined with the waste plastic material, Alternatively, it may be separately supplied into the heating furnace, and in this way, when the chlorine gas mixed with the sodium gas flows to the cooling device through the vaporized gas extraction pipe, it is 200 degrees. When the temperature drops to about C, it has been found that chlorine is preferentially combined with sodium to form a salt (NaCl) so that sodium can select sodium and bind to it. Furthermore, if water of about 15 to 20% in weight ratio is supplied to the waste plastic material to be supplied into the heating furnace, water vapor gas generated in the heating furnace from the water together with the vaporized gas. When it reaches the inside of the cooling device through the vaporized gas take-out pipe and condenses into water by cooling with the cooler, a salt (NaCl) in which sodium and chlorine are combined and fixed is combined with the condensed water. Oil and fat components are separated and stored in two layers at the bottom of the tray or receiver that is provided in the cooler so as to receive the oil and fat components that are dissolved and become salt water to condense. It has been found that it can be taken out by a water drain pipe provided at the bottom of the receiver.

そして、このことから、本発明においては、上述の課題を解決するための手段として、請求項１に記載したように、加熱炉に、廃プラスチック材を投入し、加熱処理によりオイル成分の気化ガスと炭素の残渣とに分解し、気化ガスを気化ガス取出管より抽き出して冷却装置に導き冷却して液化し、油脂類に油化還元する廃プラスチック材の分解処理方法において、加熱炉１内に供給する廃プラスチック材は、その廃プラスチック材の水洗により付着した程度の水を含ませた状態とし、かつ、水酸化ナトリウム、重炭酸ナトリウム等のナトリウム系触媒を混和した状態で加熱炉１内に供給し、熱処理により加熱炉１内に廃プラスチック材中の塩化ビニールに起因して生じてくる塩素ガスを、ナトリウム系触媒から生じるナトリウムガスと添加した水から生じる水蒸気ガスとに加熱炉内において混和した状態として、気化ガス取出管を介し冷却装置に導き、この間における温度降下によりナトリウム（Ｎａ）と塩素（Ｃｌ）とを結合させ、冷却装置によるさらなる温度降下により凝縮してくる水に溶解させて、塩水として取り出すことで塩素を分離除去することを特徴とする廃プラスチック材の分解処理方法、を提起するものである。   From this fact, in the present invention, as means for solving the above-mentioned problems, as described in claim 1, waste plastic material is introduced into a heating furnace, and the vaporized gas of oil component is obtained by heat treatment. In the decomposition method of the waste plastic material, the gasification gas is extracted from the vaporization gas take-out pipe, led to a cooling device, cooled and liquefied, and liquefied and reduced to oils and fats. The waste plastic material to be supplied in the heating furnace 1 is in a state where the waste plastic material contains water adhering to the waste plastic material and mixed with a sodium-based catalyst such as sodium hydroxide or sodium bicarbonate. The chlorine gas generated due to the vinyl chloride in the waste plastic material is added to the heating furnace 1 by heat treatment and sodium gas generated from the sodium-based catalyst. As a state of being mixed with water vapor gas generated from water in the heating furnace, it is led to a cooling device through a vaporized gas extraction pipe, and sodium (Na) and chlorine (Cl) are combined by a temperature drop during this time, and further by the cooling device. The present invention proposes a method for decomposing waste plastic material, characterized in that chlorine is separated and removed by dissolving in water condensed by a temperature drop and taking out as salt water.

また、これに併せて、上述の本発明手段を実施する装置として、請求項２に記載したような、周壁の外周にヒーターを装設し、それの外周を断熱材により被覆した加熱炉と、廃プラスチック材を濡れた状態のまま加熱炉内に供給可能とするフィーダーと、ナトリウム系の触媒を加熱炉内に供給する触媒フィーダーと、加熱炉内での廃プラスチック材の熱分解により生成してくる油脂成分のガスおよび水蒸気ガス等の気化ガスを加熱炉内から抽き出す気化ガス取出管と、気化ガス取出管により取り出される気化ガスを冷却して、油脂分のガスと水分のガスとを凝縮させる冷却装置とからなり、その冷却装置には、熱交換器よりなる冷却器を気密に収蔵する冷却ボックスと、冷却器による冷却により凝縮・液化してくる油脂分および水分を受けるよう前記ボックス内に設ける受器とを装備せしめ、その受器の底部に、油層と塩水層とに２層の分離して貯留される油脂と水とのうちの水を取り出す水排出管を接続し、それよりも上位に油脂を取り出す油排出管を接続したことを特徴とする廃プラスチック材の油化処理装置、を提起するものである。   In addition to this, as a device for carrying out the above-described means of the present invention, a heating furnace in which a heater is installed on the outer periphery of the peripheral wall as described in claim 2, and the outer periphery thereof is covered with a heat insulating material, It is generated by a feeder that can supply waste plastic material in the heating furnace in a wet state, a catalyst feeder that supplies sodium-based catalyst into the heating furnace, and thermal decomposition of the waste plastic material in the heating furnace. The vaporized gas extraction pipe for extracting the vaporized oil component gas and vaporized gas such as water vapor gas from the inside of the heating furnace, and the vaporized gas taken out by the vaporized gas extraction pipe are cooled so that the oil and fat gas and moisture gas are It consists of a cooling device that condenses, and receives the oil and fat and moisture that are condensed and liquefied by cooling with the cooling box and the cooling box that stores the cooler consisting of a heat exchanger in an airtight manner. A receiver provided in the box is connected, and a water discharge pipe is connected to the bottom of the receiver to extract water out of the oil and water stored separately in two layers, an oil layer and a salt water layer. In addition, the present invention proposes an oil plasticizing apparatus for waste plastic material, characterized in that an oil discharge pipe for extracting oil and fat is connected to a higher position.

本発明による廃プラスチック材の分解処理手段は、廃プラスチック材を加熱炉内に投入して加熱処理により油脂成分に分解し、その気化ガスを冷却装置に導き冷却し液化して油脂類に油化還元する分解処理において、廃プラスチック材中の塩化ビニール材に起因して加熱炉内に生成してくる塩素ガスを、ナトリウムと結合させて塩（ＮａＣｌ）として固定し、これを水に溶解させて塩水の形態として分離除去するのに、加熱炉内には、重炭酸ナトリウム、水酸化ナトリウム等のナトリウム系触媒を廃プラスチック材に混和して投入することで、ナトリウムのガスを存在させ、さらに、加水により加熱炉内に水蒸気ガスを存在させるようにしているのだから、塩素ガスとナトリウムガスと水蒸気ガスとが混ざりあった状態で気化ガスと共に気化ガス取出管を介し冷却装置に送り込まれていくときに、２００度付近に温度降下したところで、ナトリウムガスと塩素ガスとの分子間結合が効率的に行われ、さらに水蒸気ガスから復水してくる水に対する溶解が効率的に行われるようになる。   The waste plastic material decomposition treatment means according to the present invention is a method in which the waste plastic material is put into a heating furnace and decomposed into oil and fat components by heat treatment, and the vaporized gas is led to a cooling device to be cooled and liquefied to be oiled into fats and oils. In the decomposing treatment, the chlorine gas generated in the heating furnace due to the vinyl chloride material in the waste plastic material is combined with sodium and fixed as a salt (NaCl) and dissolved in water. To separate and remove in the form of salt water, sodium gas such as sodium bicarbonate and sodium hydroxide is mixed with the waste plastic material in the heating furnace, and sodium gas is present. Since water vapor gas is present in the heating furnace by hydration, it vaporizes with vaporized gas in a state where chlorine gas, sodium gas and water vapor gas are mixed. When it is sent to the cooling device through the gas extraction pipe, when the temperature drops to around 200 ° C., the intermolecular bond between sodium gas and chlorine gas is efficiently performed, and further condensate from the steam gas. Dissolution in water is efficiently performed.

本発明手段において、加熱炉内に水を供給する手段は、水が加熱炉内に供給されるようになればよく、加熱炉内に廃プラスチック材をフィーダーにより供給するときに、その廃プラスチック材に水を添加しておくことで、このフィーダーを利用して行うようにしてよい。このときの添加する水の量は、廃プラスチック材に対し重量比において略２０％程度で充分である。この量の水は、廃プラスチック材を水洗いにより洗浄したときに、洗浄し終えた廃プラスチック材がそれの表面に水が付着して濡れた状態にあるときの付着した水の量程度でよい。   In the means of the present invention, the means for supplying water into the heating furnace may be such that water is supplied into the heating furnace, and when the waste plastic material is supplied into the heating furnace by a feeder, the waste plastic material It may be carried out using this feeder by adding water. At this time, the amount of water to be added is about 20% in terms of the weight ratio with respect to the waste plastic material. This amount of water may be about the amount of attached water when the waste plastic material is washed and washed, and the waste plastic material that has been washed is wet with water adhering to its surface.

また、加熱炉内にナトリウム系の触媒を供給する触媒フィーダー３も、その触媒を加熱炉１内に供給するようになればよいものであり、前述の加水手段と同様に、廃プラスチック材を加熱炉１内に供給するフィーダー２の搬送路の途中または基端側に、触媒を送り込むようにして、フィーダー２が供給する廃プラスチック材に触媒が添加された状態となって加熱炉１内に供給されていくようにしてよい。   Further, the catalyst feeder 3 for supplying a sodium-based catalyst into the heating furnace is also only required to supply the catalyst into the heating furnace 1, and the waste plastic material is heated similarly to the above-mentioned hydration means. Supplying the catalyst into the heating furnace 1 in a state where the catalyst is added to the waste plastic material supplied by the feeder 2 in the middle of the conveying path of the feeder 2 supplied into the furnace 1 or the base end side. It may be done.

用いる触媒は、加熱炉１内に塩素ガスと結合させるナトリウムガスを存在させるためのもので、加熱によりナトリウムガスを発生させる水酸化ナトリウム、重炭酸ソーダ等を用いる。   The catalyst to be used is for allowing sodium gas to be combined with chlorine gas in the heating furnace 1, and sodium hydroxide, sodium bicarbonate, or the like that generates sodium gas by heating is used.
