Description
【０００１】[0001]
本考案は、廃プラスチックを熱溶融して減容処理する際に発生する分解ガスの 排ガス中の臭気と煙とを脱臭、脱煙する脱臭炉部が、廃プラスチックの溶融炉部 に一体化して設けられている廃プラスチックの減容処理装置に関するものである 。 In the present invention, the deodorizing furnace section for deodorizing and deodorizing the odor and smoke in the exhaust gas of the decomposition gas generated when the waste plastic is heat-melted and subjected to volume reduction processing is integrated with the waste plastic melting furnace section. It is related to the installed waste plastic volume reduction equipment.
【０００２】[0002]
従来、可燃性の廃プラスチックを減容する装置では、廃プラスチックの溶融処 理を優先的に考えて、溶融炉と、発生する排ガスの脱臭炉とを別置形としていた 。 そこで、溶融処理能力を中心に考えると、その脱臭用の脱臭炉は極めて大きく なってしまう。 Conventionally, in the equipment for reducing the volume of combustible waste plastic, the melting furnace and the deodorizing furnace for the exhaust gas generated were separated from each other, giving priority to the melting treatment of the waste plastic. Therefore, considering the melt processing capacity, the deodorizing furnace for deodorizing would be extremely large.
【０００３】 また、排ガスの完全脱臭、脱煙の際の条件、例えば 600℃から 850℃の 0.3秒 間を満すことのために、近年、都市型溶融器として１基当りの溶融処理能力は小 さくても、完全脱臭、脱煙機能を完備した装置の開発が要望されてきている。 特に、スーパー、百貨店、小規模小売店、コンビニエンスストア等で機械装置 を設置する場合、その設置面積を小さくし、かつ臭気や煙等の無公害性を最優先 して、処理能力が小さくても良いとされている。In addition, in order to satisfy the conditions for complete deodorization and smoke removal of exhaust gas, for example, 0.3 seconds from 600 ° C. to 850 ° C., in recent years, the melting processing capacity per unit as an urban melter has been increased. There is a demand for the development of equipment that is fully equipped with complete deodorization and smoke removal functions. In particular, when installing machinery in supermarkets, department stores, small-scale retail stores, convenience stores, etc., keep the installation area small and give the highest priority to pollution-free odors and smoke, even if the processing capacity is small. It is considered good.
【０００４】 一方、脱臭、脱煙を優先的に考えた場合、その脱臭炉の熱源ヒータは、稼動中 には前記完全脱臭、脱煙の条件である 600℃〜 850℃の温度を保持するために、 殆んど停止させないことになり、その脱臭、脱煙の際の燃焼による熱エネルギー を、廃プラスチックの熱溶融処理に直接または間接的に使用する場合には、その 溶融炉内の温度を通常 200℃位にコントロールしなければ、その炉内で廃プラス チックが発火するおそれがあり、そのような炉内発火を防止する必要がある。On the other hand, when priority is given to deodorization and smoke removal, the heat source heater of the deodorization furnace maintains a temperature of 600 ° C. to 850 ° C., which is the condition for complete deodorization and smoke removal during operation. In addition, the temperature in the melting furnace is almost never stopped, and when the thermal energy from the combustion during deodorization and smoke removal is used directly or indirectly for the thermal melting process of waste plastic, Unless the temperature is normally controlled to around 200 ° C, waste plastic may ignite in the furnace, and it is necessary to prevent such ignition in the furnace.
【０００５】[0005]
本考案は、前記のごとき従来の要望に応えるためになさたものであり、脱臭、 脱煙を優先的に追求でき、しかも設置スペースも少なく、かつ炉内での廃プラス チックの発火を防止できる廃プラスチックの減容処理装置を提供することを解決 課題としたものである。 The present invention has been made to meet the above-mentioned conventional demands, and can preferentially pursue deodorization and smoke removal, has a small installation space, and can prevent the ignition of waste plastic in the furnace. The problem to be solved is to provide an apparatus for reducing the volume of waste plastic.
【０００６】[0006]
上記の課題を解決するための手段として、本考案の廃プラスチックの減容処理 装置は、炉内に投入された廃プラスチックを熱風で熱溶融処理する溶融炉部と、 その溶融炉部内で発生する分解ガスなどの排ガスを燃焼させる熱源ヒータ、例え ばバーナ及びその燃焼による熱エネルギーを溶融炉部内の廃プラスチック溶融用 の熱風として熱回収する熱交換器を有する脱臭炉部とを一体化することにより構 成されるが、上記の溶融炉部内が所定の設定温度に到達したら、それを溶融炉部 内に取付けた温度センサーなどにより感知し、自動的に水スプレーを噴射する水 スプレーノズルを溶融炉部内に設けることが、炉内での廃プラスチックの発火を 防止する上で好ましい構成である。 As a means for solving the above-mentioned problems, the waste plastic volume reduction processing apparatus of the present invention is generated in the melting furnace section for thermally melting the waste plastic put in the furnace with hot air and in the melting furnace section. By integrating a heat source heater that burns exhaust gas such as cracked gas, for example, a burner and a deodorizing furnace section that has a heat exchanger that recovers the heat energy from the combustion as hot air for melting the waste plastic in the melting furnace section. When the temperature inside the melting furnace reaches the specified temperature, it is detected by a temperature sensor installed inside the melting furnace, and the water spray nozzle that automatically sprays water spray is installed in the melting furnace. It is a preferable structure to prevent the ignition of the waste plastic in the furnace by providing it inside the section.
【０００７】[0007]
以下図面を参照して本考案の実施例を説明するが、図面は本考案の廃プラスチ ックの減容処理装置の一実施例における概略側断面図である。 まず、この装置は、Ａで示す脱臭炉部と、Ｂで示す溶融炉部とを一体化したも のであり、溶融炉部Ｂの上部の投入口４から投入された廃プラスチック１２は、 脱臭炉部Ａの熱交換器９で熱交換された間接熱風Ｈにより熱溶融によって減容化 され、シュータ１３経由降下して、受箱６内で固化され、受箱６ごと受箱取出口 ５から取り出される。 Embodiments of the present invention will be described below with reference to the drawings, which are schematic side cross-sectional views of an embodiment of the waste plastic volume reduction processing apparatus of the present invention. First of all, this apparatus has a deodorizing furnace section indicated by A and a melting furnace section indicated by B which are integrated. The waste plastic 12 injected from the charging port 4 at the upper part of the melting furnace section B is The volume is reduced by heat fusion by the indirect hot air H exchanged by the heat exchanger 9 of the part A, the volume is lowered via the shooter 13, the solidified in the receiving case 6, and the receiving case 6 is taken out from the receiving case outlet 5. Be done.
【０００８】 その際、溶融炉部Ｂ内で発生する排ガスである分解ガスＧは、煙道１０から吸 引ブロアー２により脱臭炉部Ａ内に誘導され、熱源ヒータであるバーナ１により 完全燃焼され、熱交換器９を通して脱臭、脱煙処理ずみの排ガスＧｗとなって排 気筒１１より外部に排出される。 一方、熱交換ブロアー３は、上記燃焼による熱エネルギーから熱交換器９で熱 回収によって得られた間接熱風Ｈを溶融炉部Ｂ内へ送り込む圧送用ブロアーの役 目をしている。At that time, the decomposed gas G which is the exhaust gas generated in the melting furnace section B is guided from the flue 10 into the deodorizing furnace section A by the suction blower 2 and completely burned by the burner 1 which is a heat source heater. After passing through the heat exchanger 9, the exhaust gas Gw that has been deodorized and smoked is discharged from the exhaust cylinder 11 to the outside. On the other hand, the heat exchange blower 3 functions as a pressure blower for sending indirect hot air H obtained by heat recovery from the heat energy from the combustion in the heat exchanger 9 into the melting furnace section B.
【０００９】 次に、溶融炉部Ｂ内には複数の水スプレーノズル８が設けられ、間接熱風Ｈの 流路に設けられた温度センサー７が設定温度に到達したことを感知すると、自動 的に水スプレーノズル８から水スプレーが噴射するようになっている。 以上の構成からなる減容処理装置により発泡スチロール等の廃プラスチック１ ２を熱処理する際には、溶融炉部Ｂ内で発生する分解ガスＧの排ガスを脱臭炉部 Ａで燃焼させ、その熱エネルギーを、熱交換器９を介して間接的な間接熱風Ｈと して熱回収しており、その間接熱風Ｈを再び廃プラスチック１２の溶融炉部Ｂへ 導入し、脱臭と溶融処理とを同時に行なうものであるが、熱源用ヒータであるバ ーナ１などは脱臭炉部Ａのみにあり、溶融炉部Ｂにはヒータまたはバーナ等はも っていない。Next, a plurality of water spray nozzles 8 are provided in the melting furnace section B, and when the temperature sensor 7 provided in the flow path of the indirect hot air H senses that the set temperature is reached, it automatically Water spray is adapted to be sprayed from the water spray nozzle 8. When the waste plastic 12 such as Styrofoam is heat-treated by the volume reduction apparatus having the above structure, the exhaust gas of the decomposition gas G generated in the melting furnace section B is burned in the deodorization furnace section A, and its thermal energy is changed. , Heat is recovered as indirect indirect hot air H through the heat exchanger 9, and the indirect hot air H is again introduced into the melting furnace section B of the waste plastic 12 to simultaneously perform deodorization and melting treatment. However, the burner 1 as a heat source heater is only in the deodorizing furnace section A, and the melting furnace section B does not have a heater or a burner.
【００１０】 すなわち、脱臭炉は一般的に排ガスの二次燃焼方式の条件として通常 600℃か ら 850℃の高温で 0.3秒間以上加熱して完全燃焼させることが必要条件とされて いるため、脱臭炉側に熱源ヒータのバーナ１を設け、脱臭、脱煙を優先的に考え たのが本考案の装置であり、廃プラスチック１２の処理能力よりも無公害性を追 求したことを特徴としている。That is, in the deodorizing furnace, it is generally required as a condition for the secondary combustion method of the exhaust gas to heat it at a high temperature of 600 ° C. to 850 ° C. for 0.3 seconds or more to completely burn it. The burner 1 of the heat source heater was installed on the furnace side, and the device of the present invention was designed to give priority to deodorization and smoke removal, and is characterized by pursuing pollution-free rather than processing capacity of the waste plastic 12. ..
【００１１】 また、この溶融炉部Ｂ内を通常 200℃位に維持する温度コントロールは、脱臭 炉部Ａを優先的に考えて熱源バーナのヒータ１は、その稼動中、600 ℃から 850 ℃を保持するため、殆んど停止させないことから、溶融炉部Ｂ内に取付けた温度 センサー７が設定温度に到達したら、数個所に設けた水スプレーノズル８から自 動的に水スプレーを噴射させて、溶融炉内での廃プラスチックの発火を防止でき る。In addition, the temperature control for maintaining the inside of the melting furnace part B at about 200 ° C. is usually performed by setting the heater 1 of the heat source burner at 600 ° C. to 850 ° C. while the deodorizing furnace part A is given priority. The temperature sensor 7 installed in the melting furnace section B reaches a preset temperature by holding the temperature sensor 7 so that the water spray nozzles 8 provided at several places automatically spray a water spray. It is possible to prevent ignition of waste plastic in the melting furnace.
【００１２】[0012]
以上に説明した本考案の廃プラスチックの減容処理装置によれば、溶融炉部と 脱臭炉部とを一体化することにより設置スペースを小さくできると共に、脱臭、 脱煙を最優先させ、その熱源ヒータを脱臭炉部の１個所のみとして、その装置の 省エネルギー化をはかりうるという効果がある。 According to the waste plastic volume reduction processing apparatus of the present invention described above, the melting furnace section and the deodorizing furnace section can be integrated so that the installation space can be reduced, and deodorization and smoke removal are given the highest priority, and the heat source Only one heater is provided in the deodorizing furnace section, which is effective in saving energy in the apparatus.
【００１３】 また、溶融炉部内の廃プラスチックの発火に対する安全性を考え、溶融炉内に 間接熱風のみを導入しており、熱源ヒータのバーナの直火、炎、すす等が絶対に 溶融炉部内に入らないようにし、温度コントロールも新鮮な空気（酸素）との混 合による方式をとらずに、水スプレー噴射方式を採用しているので、炉内発火を 防ぐ上で極めて有効である。In consideration of safety against ignition of waste plastic in the melting furnace section, only indirect hot air is introduced into the melting furnace so that the direct burner, flame, soot, etc. of the heat source heater will never melt inside the melting furnace section. Temperature control, and the temperature control does not take the method of mixing with fresh air (oxygen), but adopts the water spray injection method, which is extremely effective in preventing ignition in the furnace.
