等の塊状燃焼物を塊状状態のままで燃焼させるための燃
焼方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a combustion method for burning lump-like combustion materials such as waste tires, waste plastic products, waste covered electric wires, etc. in the lump state.
従来、流動層焼却炉でこの種塊状燃焼物を燃焼させよう
とする場合は短時間に燃え残りのない完全燃焼させるた
めに細かく破砕して、これを流動層全面に散布投入する
のが一般的であった。その理由とするところは、塊状の
まま流動層に投入するとその表面が熱い流動媒体と激し
く接触するため表面は細破砕されて表面積が増大し直ち
に発火点に達して発火し、すみやかに燃焼してしまい、
−時的かつ局部的に酸素不足や流動媒体の過熱が生じて
不完全燃焼やクリンカの発生が生しるという問題点や、
また塊状のために連続的にしかも定量的に流動層に供給
することが困難で燃焼管理が難かしいことと、燃料とし
て使用した場合には発生熱量の変動が避けられないため
例えば蒸気ボイラにあっては蒸気発生量や蒸気圧力が変
化し、また流動媒体の温度や発生排ガスの温度風量も変
化するために運転制御が難かしいという点にあった。Conventionally, when attempting to burn this type of lumpy combustion material in a fluidized bed incinerator, it is common practice to crush it finely and scatter it over the entire surface of the fluidized bed in order to achieve complete combustion without any unburned remains in a short period of time. Met. The reason for this is that when a lump is put into a fluidized bed as it is, its surface comes into intense contact with the hot fluidized medium, causing the surface to become finely crushed, increasing the surface area, and immediately reaching the ignition point, causing it to ignite and burn quickly. Sisters,
- Problems such as temporal and local oxygen shortages and overheating of the fluidized medium, resulting in incomplete combustion and clinker generation;
Furthermore, since it is a lump, it is difficult to supply it continuously and quantitatively to a fluidized bed, making combustion management difficult. Also, when used as fuel, fluctuations in the amount of heat generated are unavoidable, so for example, it is difficult to control the amount of heat generated in a steam boiler. However, the amount of steam generated and the steam pressure change, as well as the temperature of the fluidized medium and the temperature and air volume of the generated exhaust gas, making operation control difficult.
なお、塊状燃焼物の燃焼方法として流動層を使用しない
でストーカ式、ロータリーキルン式等により空気を多量
に供給しながら時間をかけて燃焼させる方法もあった。In addition, as a method of combustion of lumpy combustion materials, there is also a method of burning over a long period of time while supplying a large amount of air using a stoker type, a rotary kiln type, etc. without using a fluidized bed.
ところが、破砕機により前記の塊状燃焼物を細かく破砕

これらが通常炉内作業のため一層困難であった。However, when the above-mentioned lumpy combustion material is finely crushed by a crusher, metal pieces, ceramic pieces, metal wires used in tires, covered electric wires, steel wires for binding, etc. may damage the crusher's crushing teeth, or This or the incombustible material discharge device became entangled, requiring a great deal of effort and expense for repair and operation and maintenance. In addition, in the case of a combustion method that does not use a fluidized bed, there will be a local oxygen deficiency in the furnace, and at the same time there will be an excess of oxygen elsewhere, resulting in black smoke, CN,
A large amount of harmful gas such as 0 is generated, a high concentration of NOx is generated, and the furnace material is easily damaged by pit heat and corrosive gas.
In addition, a large amount of unburned remains and metal wires are entangled, making it difficult to discharge and dispose of the residue inside the furnace, which requires a great deal of effort and expense for repair costs and operation and maintenance. It was even more difficult because the work was inside the furnace.
本発明は、従来問題であったこの種塊状燃焼物の焼却に

全で安価な燃焼方法を提供することを目的とするもので
ある。The object of the present invention is to provide a safe and inexpensive combustion method in terms of labor, expense, and pollution when incinerating this kind of lumpy combustion material, which has been a problem in the past.

を提供するものである。Means for Solving Problem C] In order to achieve the above-mentioned object, the present invention operates a fluidized medium made of granular solids in a combustion furnace at a temperature higher than the ignition point of the combustible material, and at a temperature higher than the melting point, softening point, and sintering point of the fluidized medium. While keeping the temperature lower than any of the nodes, a gas containing oxygen is diffused from the bottom to form a fluidized bed, and the lumpy combustion material is put in the lumped state into the fluidized bed. The present invention provides a method for burning lumpy combustible materials, which is characterized by controlling the input frequency and the quantity per frequency.

収するようにしたものである。In the present invention, when burning bulk combustion materials such as waste tires, waste plastic products, and waste coated electric wires, the materials are placed in a fluidized bed in a furnace in almost their original shape without being subjected to a crusher, and are then buried in a fluidized bed. By minimizing the surface exposed to heat, smooth combustion can be achieved as a fluidized bed combustion, and by controlling the combustion by adjusting the input frequency and the quantity per frequency, complete combustion can be achieved continuously. It made it possible. In addition, the metal wires contained in these combustion materials are entangled and rolled into particles due to the swirling flow of the fluidized medium, and are smoothly discharged from the furnace together with the fluidized medium, and are separated from the fluidized medium by a classifier. The granular lumps of metal wire are collected.
本発明者らは、公知の流動層焼却炉（例えば特開昭５７
−１２４６０８号公報参照）を使用し、次の実験を行い
数々の知見を得た。The present inventors have developed a known fluidized bed incinerator (for example, JP-A-57
-124608), the following experiments were conducted and a number of findings were obtained.
（１）廃タイヤ燃焼
先づ、焼却炉煙道にジルコニア式酸素濃度センサーを挿
入しこれにより応答性の高い排ガスの酸素濃度連続記録
をしながら普通自動車用スチールラジアルタイヤを焼却
炉内流動層の中心部に投入した。(1) Before burning waste tires, a zirconia oxygen concentration sensor is inserted into the flue of the incinerator, which continuously records the oxygen concentration of the exhaust gas with high responsiveness. Inserted into the center.
その結果、排ガス中の酸素濃度は第１図に示すように変
化した。煙突からの排煙も格別異なるものはな（、同時
に６本投入した時にも排ガス中の酸素濃度低下ピーク時
にわずかに希薄な白煙が視認された程度であった。また
炉内は熱した火炎で充満した状態となり、良好な状態を
示していた。As a result, the oxygen concentration in the exhaust gas changed as shown in FIG. The exhaust smoke from the chimney was also not particularly different (even when six pipes were injected at the same time, only a slight amount of thin white smoke was visible at the peak of the oxygen concentration drop in the exhaust gas). It was filled with water, indicating a good condition.
したがって廃タイヤを安定状態で燃焼させるには排ガス
中の酸素濃度５％位が適当と考えられる。Therefore, an oxygen concentration of about 5% in the exhaust gas is considered appropriate for stable combustion of waste tires.
第１図に示すように廃タイヤ投入後約１分で燃焼のピー
クがくる。１回の投入量を６本とすると、ピーク時の排
ガス中の酸素濃度が約３〜４％となり、僅かに希薄な白
煙が目視された。そこで投入量を５本とすればピーク時
の酸素濃度は約６〜７％程度と予測される。廃タイヤ５
本を１分間隔で間欠的に投入した場合の酸素濃度を第２
図に示す。As shown in Figure 1, combustion peaks approximately 1 minute after the waste tire is introduced. When the amount of gas added at one time was 6, the oxygen concentration in the exhaust gas at the peak time was about 3 to 4%, and slightly thin white smoke was visually observed. Therefore, if the input amount is 5 bottles, the oxygen concentration at the peak is predicted to be about 6 to 7%. waste tires 5
The oxygen concentration when books are intermittently added at one-minute intervals is the second
As shown in the figure.
すなわち、廃タイヤ５本を１分間隔で投入すると、排ガ
ス中の酸素濃度は約５％で安定な燃焼が！！続される。In other words, if you add 5 scrap tires at 1-minute intervals, the oxygen concentration in the exhaust gas will be approximately 5%, resulting in stable combustion! ! Continued.
このことは、１回の廃タイヤ投入本数を少なくする場合
には投入間隔を短かくすればよい。また燃焼炉の大きさ
によって投入本数と、投入間隔を適宜選択することによ
って排ガス中の酸素濃度を約５％以上に保持しながら焼
却することが可能である。第３図は廃タイヤ１本を３０
秒間隔で投入した場合の排ガス中の酸素濃度を示すもの
である。This means that if you want to reduce the number of scrap tires you put in at one time, you can shorten the throw-in interval. Further, by appropriately selecting the number of fuels to be introduced and the interval between charges depending on the size of the combustion furnace, it is possible to incinerate while maintaining the oxygen concentration in the exhaust gas at about 5% or more. Figure 3 shows 30 pieces of one waste tire.
This shows the oxygen concentration in the exhaust gas when it is injected at intervals of seconds.
なおラジアルタイヤ中の金属線はかなりきつめにからみ
あった１０〜２０ｃｍ程度の多数の粒状の塊として流動
媒体より分離排出された。Note that the metal wires in the radial tire were separated and discharged from the fluid medium as a large number of granular lumps approximately 10 to 20 cm in size that were quite tightly intertwined.

のは見当らなかった。(2) Metal wire incineration A large amount of steel wire, commonly known as annealed steel wire with a diameter of 3 fi and a length of about 2 m, was put into an incinerator and its behavior was observed. As a result, all the steel wires that were introduced had a large number of 10~
20c1) A lump with a diameter of the following is formed and is discharged from the fluidized medium circulation line to remove noncombustibles from the fluidized bed, that is, during operation, is discharged from the furnace together with the fluidized medium by a noncombustibles removal conveyor while maintaining a seal inside and outside the furnace. A vibrating sieve, which is a material classification device, removes the non-combustibles from the fluidized medium below the sieve, which is returned to the furnace. Thereafter, the furnace was shut down, all fluidized media was discharged, and the inside of the furnace was inspected. As a result, no fluid remained in the hearth.

外に排出される。Observing the above experiment, when a tire is placed in the fluidized bed and falls to the center surface of the fluidized bed, it is buried in the overflowing fluidized medium and sinks in the descending layer, heated by the fluidized bed, becomes steamed, and starts rising from the bottom of the descending layer. It is swept away by the swirling flow of the fluidized medium at the bottom of the rising layer, and combusts at the main part of the rising layer due to collision between sufficient oxygen and the violent fluidized medium. The remaining metal steel wire is scratched and softened by the high temperature of 600 to 900 degrees Celsius in the fluidized bed, and as a result, it is quickly rolled up by the movement of the swirling flow of the fluidized medium in the fluidized bed and becomes a granular lump of 10 to 20 cm or less. , they are swept up and collected at the bottom of the lower side of the diffuser surface by the movement of the swirling flow. From there, it passes through a chute, enters a noncombustible material removal conveyor together with a fluidized medium, and is discharged out of the furnace.

The separated metal wire lumps are carried out and stored on a conveyor.

って完全燃焼を連続的に行なうようにしたものである。The present invention eliminates the need to crush combustible materials such as waste tires, waste plastic products, and waste covered electric wires, which have traditionally been considered difficult.
This makes it possible to perform fluidized bed combustion in the round state, and by putting the lumpy combustion material into the fluidized medium, the surface exposed to the fluidized medium is minimized and it is covered as fluidized bed combustion. To achieve this, complete combustion is achieved continuously by controlling combustion by adjusting the amount of fuel injected into the furnace and its frequency.

It is possible to recover heat from the exhaust gas or from the fluidized medium using a fluidized bed boiler, which is an energy saving measure. Furthermore, there is no need for a crusher, which was conventionally required, and the metal wire can be smoothly discharged, thereby reducing the labor and expense required for furnace maintenance.
