【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、カーシュレッダダストの処理方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for treating car shredder dust.
廃車を破砕機で破砕し、スクラップを回収する際に排出

。The amount of scrap dust emitted when scrap cars are crushed using a crusher and recovered is estimated to be approximately 78 tons in fiscal 1988. This scrap dust is a mixture of combustible materials such as rubber, fibers, and plastics and non-combustible materials such as glass and metals, and since plastics are vinyl chloride, which generates harmful hydrogen chloride gas when incinerated, it is not used as fuel. Currently, it is difficult to make effective use of the waste, so it is currently disposed of in landfills. However, the number of suitable sites for landfill disposal is decreasing year by year, and the cost of disposal is also rising as the amount of waste increases, so there is a need for the development of practical treatment means.

い。As one way to use shredder dust as fuel, a system has been proposed in which the dust is heated to dehydrochlorinate it, while plastics are melted and molded into pellets to produce solid fuel, and a test plant is currently in operation. However, it is not economical because it requires treatment of the hydrogen hexachloride that is generated, and it is heated above the temperature required for melting glass sticks other than vinyl chloride, which also generates harmful gases other than hydrogen chloride. It cannot be said that it is preferable in terms of the impact on the environment.

ダストの処理方法である。The present invention crushes car shredder dust with any type of crusher, divides it into multiple groups according to particle size, uses the group of organic substances with a small proportion of chlorine-based plastic as fuel, and further crushes the other groups. This is a method for treating car shredder dust, which is characterized by kneading and solidifying the car shredder dust while heating.

ことを新規とするものである。That is, the present invention crushes car shredder dust and separates it according to its particle diameter, extracts a part of the combustibles as fuel, and selects the remainder within a range where most of the plastic melts after crushing and does not generate hydrogen chloride gas. What is new is that the assimilation is performed at a temperature of .
