おいても燃焼効率が低く、かつ多量の燃焼空気を必要と
するため排ガス処理設備が非常に大型になるという問題
があってこれらの方法は採用し難かった。また他の微粉
炭燃焼のような方式により焼却処理しようとしても。In the nuclear power field, etc., the amount of wet coarse waste ion exchange resin extracted from the ion exchange treatment process has increased significantly, and the establishment of technology to reduce its volume has become an issue. However, even if conventional methods such as rotary gill, multi-stage furnace, fluidized bed furnace, and stirred hearth furnace are used to incinerate waste ion exchange resin, it will not work. However, these methods had low combustion efficiency and required a large amount of combustion air, making the exhaust gas treatment equipment extremely large, making it difficult to adopt these methods. Even if you try to incinerate it using other methods such as pulverized coal combustion.

It is necessary to crush the powder to a size of 0.00 mesh or less and dry it in a specified manner, which makes the equipment complex and requires sophisticated techniques and 7/1 measures to prevent dust explosions. This method was also difficult to adopt.
本発明はこのような従来の問題点に鑑みて発明されたも

のである。The method for incineration of waste ion exchange resin according to the present invention which achieves this objective is to mix the moistened coarse waste ion exchange resin with fuel oil and water in the presence of a laxative to obtain a three-component oil-in-water type product. The system is characterized by forming a stable emulsion and then spraying and burning this in a single machine or in auxiliary combustion soil.

は粗い樹脂であって、かつ湿潤されておジ、これを燃料
油または水のみと混合しても安定な均一分散体を得るこ
とが困難であるが。The waste ion exchange resin taken out from the ion exchange treatment process is a coarse resin and is wet, so it is difficult to obtain a stable homogeneous dispersion even if it is mixed with fuel oil or water alone. .

本発明の目的をより十分に達成することが困難である。Note that a water-in-oil emulsion can also be obtained by mixing the waste ion exchange resin with fuel oil and water in the presence of a water-in-oil emulsifier; difficult to achieve.

液（燃料油と水とを混合した液）との重量比が大きくな
るにつれても流動性が悪化するためである。This is because this type of emulsion has a high concentration of water compared to fuel oil.
If t increases, the fluidity at room temperature will deteriorate and the liquid feeding operation will become difficult. This is because fluidity deteriorates as the weight ratio of the wetted coarse waste ion exchange resin and the mixed liquid (liquid mixed with fuel oil and water) increases.

十分に達成し得ないことがわかる。Table 2 (Water-in-oil emulsion) As is clear from this, the water-in-oil emulsion is significantly inferior in fluidity to the oil-in-water emulsion shown in Table 1, and (R/L) The amount of fuel oil used per waste ion exchange resin increases.
Therefore, it can be seen that the objects of the present invention cannot be more fully achieved with water-in-oil emulsions.

し得ないことは述べる寸でもなく明らかである。Table 3 (Emulsion without the addition of either water or diesel oil and an emulsifier) According to this example, the emulsion stability is insufficient, so it can be stated that even if this emulsion is used, the object of the present invention cannot be achieved. But it's obvious.

また乳化剤はノニオン型界面活性剤が好ましく。Further, the emulsifier is preferably a nonionic surfactant.
カチオン及びアニオン型活性剤を用いると廃イオン交換

性を維持し難い。When cationic and anionic activators are used, they react with the waste ion exchange resin and reduce the emulsifying ability, making it difficult to maintain stable emulsifying properties for a long period of time.

を生成するが１次いでこれを噴Ｍ燃焼させるのである。In the present invention, as described above, the coarse waste ion exchange resin is wetted in the presence of an emulsifier. It is mixed with CrA oil and water to form a stable three-component emulsion in the form of oil-in-water droplets, which is then combusted.

ことにより油中水滴型エマルジョンの場合に比して各種

という効果が得られる。In other words, if the amount of water added is increased, the viscosity of the emulsion will decrease (in the case of water-in-oil type, it will increase).
Therefore, when lowering the exhaust gas temperature to a predetermined level, the amount of water added can be easily increased, and the effect is that the amount of combustion air can be maintained at a minimum.

う効果が得られる。Secondly, the amount of fuel used per amount of waste ion exchange resin can be reduced, and thirdly, even when using high viscosity oil such as C heavy oil, the viscosity of the emulsion is reduced by the continuous phase. Since the viscosity of water converges to a certain level, fluidity that can be sprayed at room temperature can be obtained.Fourthly, even if the emulsion flows, there is no accumulation of static electricity, so there is a risk of ignition and explosion in the gas phase. (In the case of water-in-oil type, it is dangerous).

度の火炎を通過するからその燃焼を効率よく行うことが
できるので完全燃焼が達成できる。As detailed above, various excellent effects can be obtained according to the present invention.To explain in more detail here, one of them is that it facilitates complete combustion and reduces the amount of exhaust gas. It will be done. In other words, in order to reduce the amount of exhaust gas per amount of waste ion exchange resin processed, it is desirable to make the amount of combustion air close to the theoretical combustion air ratio by liquid burning the resin, and to burn the resin completely, as much as possible. Although it is necessary to pass through a high temperature zone, 9 In the present invention, the resin is mixed with fuel oil etc. to form a stable uniform dispersion with good fluidity that can be handled as a liquid fuel,
This is sprayed and burned. Since the resin always passes through the high-temperature flame, its combustion can be carried out efficiently and complete combustion can be achieved.

はない。Secondly, there is an effect that fuel can be saved and NOx can also be reduced15). That is, if the uniform dispersion of the emulsion can be stably maintained, steady spray combustion can be maintained and the ignition of the resin can be stabilized, so there is no need to raise the total temperature in the furnace excessively, which is necessary for complete combustion.

ロールで行うことができる。In general incineration treatment, when the temperature inside the furnace becomes excessively high, a method is adopted in which the total amount of combustion air is increased to lower the temperature, but in the present invention, the calorific value of the waste resin emulsion is reduced by adding water. Since it can be easily adjusted by changing the amount, it is possible to prevent an excessive rise in the furnace temperature while maintaining the combustion air amount close to the total theoretical air amount, mainly by changing (0/W). Furthermore, when (0/W) is small and the calorific value of the emulsion is low, spray combustion is performed with the auxiliary combustion soil, so that the temperature inside the furnace can be adjusted by controlling the auxiliary combustion fuel.

次にその３として、微粉砕及び乾燥などの前処理を省く
ことができるという効果が得られる。Note that the addition of water greatly contributes to reducing NOx by preventing an excessive rise in the temperature inside the furnace and making the combustion flame temperature distribution uniform. In addition, it is desirable to use as little fuel as possible per waste ion exchange resin, but in water-in-oil emulsions, it is clear from the comparative example in Table 2 that < (0/W) '&
If it is lowered or increased (R/L)ffi, the fluidity deteriorates and it is difficult to obtain stable spray combustion. The oil-in-water emulsion according to the present invention (in which (R/L) is (6
0/40), complete combustion is easy, and therefore fuel consumption can be reduced. Thirdly, pretreatment such as pulverization and drying can be omitted.

細化することができる。The ion exchange resin of f19' is a thermosetting polymer material such as a crosslinked copolymer of styrene and divinylbenzene, and a large amount of water is contained inside the waste ion exchange resin particles. However, the drying speed is extremely slow. However, in the present invention, since the oil-in-water emulsion can be spray-combusted to produce a high-temperature combustion flame, even waste ion exchange resin having a particle size of about 1M can be crushed in the flame and made into fine particles.
すなわち燃焼時においては樹脂粒子内包含水の逸散速度
