Description

  In the present invention, organic waste including waste tires and the like is dry-distilled to generate cracked gas, and active components in the gas are extracted, or steam heating or drying is performed using a high-temperature cracked gas as a heat source. The present invention relates to a waste gasification combustion system.

In recent years, the generation amount of used tires among industrial wastes has been increasing at an annual rate of about 20%, so that wastes such as waste tires can be safely processed and the generated combustion heat can be used effectively. Technology has been developed. In the waste gasification and combustion system for the treatment of waste containing organic matter, combustible gas such as methane and ethane and oil liquid such as kerosene and light oil contained in the dry distillation gas are extracted. To use it.
That is, in a conventional waste gasification combustion system, waste such as rubber tires is charged into a dry distillation tower and ignited, and the waste is heated in a state of lack of oxygen. The waste in the carbonization tower is thermally decomposed and partly reduced in molecular weight and volatilized. The generated carbonization gas is introduced into a condenser, and the high boiling point component gas contained in the gas is liquefied and extracted. For example, the following techniques are known in connection with a waste gasification combustion system having such an oil liquid component extraction device.

  In Patent Document 1, a pyrolysis furnace that decomposes waste by heating, a condenser that stores and liquefies cracked gas generated in the pyrolysis furnace through a gas feed pipe, and remains in the condenser In a waste treatment system comprising a gas combustion device for burning cracked gas, a waste treatment system is described in which condensate liquefied by a condenser is returned to a thermal decomposition furnace and sprayed onto the waste.

In Patent Document 2, when carbonic product waste materials and waste plastic materials such as old tires are carbonized, a gas component generated by carbonization is introduced into a condenser to liquefy the high-boiling component and the liquefied high-boiling component Of a rubbery or plastic product waste material that captures a high-boiling component in the low-boiling component-containing gas by bringing a part of the product into contact with the low-boiling-component-containing gas and increases the recovery rate of the liquid component The law is described.

However, in the waste treatment system in which the condensate obtained by liquefying the cracked gas described in Patent Document 1 is returned to the thermal decomposition furnace and sprayed on the waste, the condensate once formed by cooling and condensation is heated again. Since it is returned to the cracking furnace, there is a risk of reducing the overall thermal efficiency, and the combustible components in the exhaust gas discharged from the condenser are likely to fluctuate and are difficult to adjust. There was a problem that it was difficult to control and lacked controllability of driving.
