CB is trichlene, chlorinated benzene, or the like, which may generate dioxin by combustion. PCB is an oily liquid in which 5-9 chlorine atoms are bonded to biphenyl having two benzene rings bonded. Because it is chemically stable and nonflammable, it does not completely decompose even if burned, and generates toxic gas. There is fear.
When released into the natural world, they are not decomposed and are accumulated in living organisms, causing environmental destruction by the food chain.

Generally, PCBs are oxidatively decomposed at a high temperature of 00 to 1.400 ° C., but a method of increasing the combustion efficiency by adding about 5% of water has also been proposed. However, the source of PCB toxicity is chlorine, especially chlorine attached to the benzene ring. PCBs and dioxins that should have been decomposed during combustion may be recombined with chlorine remaining on the benzene ring remaining in the cooling process and dioxins may be regenerated. Therefore, if this chlorine is removed and the benzene ring is completely decomposed, the regeneration of dioxins will be eliminated and the decomposition should be complete.

It is characterized by dissolving or suspending an alkaline earth metal compound such as magnesium and calcium oxide, and injecting a fuel mixture emulsified and mixed into a combustion furnace for combustion. According to this method, since chlorine is removed, the decomposition of the organic chlorine compound is completed, and heat such as electric power can be used because no corrosive gas is generated.

の差が、エネルギーとして得られるという方法である。[0007] The method of the present invention will be described in more detail. When an organic chlorine compound is added to the water-soluble fuel and a metal compound which easily combines with chlorine such as caustic soda in the water when the water-fuel is burnt, the atomized fuel is added. The reaction takes place in phase. Water is usually sprayed into a combustion furnace maintained at a high temperature, and the water in the fuel is decomposed using the energy of steam explosion and the like. It is a method that can be obtained as.

However, if the energy of steam explosion is used or water is easily decomposed, for example, when the oxidation-reduction potential is lowered, the thermal decomposition temperature of water of 4.000 ° C. or more becomes 600.

At this time, when the organic chlorine compound and caustic soda are contained in the hydrofuel or sprayed into the combustion furnace, Na of caustic soda and Cl of the organic chlorine compound react in the form of a shock wave of a steam explosion in a gaseous state. , NaCl, and the organic chlorine compounds are dechlorinated and turned into ordinary organic compounds.

At this time, if an organic compound is present, a water-gas-like reaction occurs, and particularly, a double bond is decomposed.

As shown by + H 2 , the reaction between carbon and H 2 O is also performed, and also reacts with C of the double bond to decompose the double bond by a water gas-like reaction as shown in Chemical formula 2. In this case, the reaction takes place in the process of H 2 O → 2H + O → H 2 O instead of the ordinary water gas reaction, and acts in a plasma state such as H + , O − , OH, etc., thus increasing the reactivity in each step. Although the benzene ring has three double bonds, it reacts with H 2 O at a temperature of 700 ° C. or more to decompose and open the benzene ring as shown in Chemical formula 3.

可能性がある。The opened benzene ring is converted into an aliphatic compound having a -CHO group (aldehyde), and other double bonds are also decomposed by a water-gas-like reaction to finally produce carbon dioxide and water via acetaldehyde. I do. Since the benzene ring has three double bonds that resonate, it has a strong bond and is not easily decomposed by ordinary combustion alone. When processing PCBs or coplanar PCBs, even if chlorine is released temporarily, the presence of the benzene ring allows cooling. At times, it may combine with chlorine again to form dioxins.

This is a safe and economical method that uses H 2 O of water 2 to 5) to completely decompose the benzene ring and not generate dioxins during cooling.

In the drawing, first, in producing a water-to-fuel fuel of oil 1: water 2 to 5, an organic chlorine compound such as PCB and trichlene is mixed into the oil. The mixing ratio is 20 to 60%, but a high concentration can be achieved by increasing the temperature of the water-fuel combustion device 1. On the other hand, a metal compound that easily binds to chlorine, such as caustic soda and caustic potash, is dissolved in water. The amount of dissolution is based on the equivalent to the chlorine of the organochlorine compound to be introduced. If the amount is too small, the dechlorination becomes insufficient, and if the amount is too large, the refractory material may be damaged.
