Abstract

PROBLEM TO BE SOLVED: To control freely the calorific power and the chlorine content of RPF product. SOLUTION: This is a process for producing RPF by dechlorinating a raw material containing chlorine such a waste plastics and the like with a deodorization apparatus 18 by heating and optionally mixing other materials from other supplying routed as waste paper and the like to the dechlorinated material. When a raw material to each supplying route is received, its chlorine content and its chlorine content are analyzed. The chlorine content of a dechlorinated material is calculated from the chlorine content of the raw material containing chlorine as such waste plastics and the chlorine removing ratio of the dechlorination apparatus 18. The calculated result is compared with an aimed chlorine content of the RPF product and the necessary almost of waste paper or the like to be mixed is determined. The supplying amount of waste paper or the like is controlled to match the calorific power of the RPF product with an aimed value. By doing this, RPF whose chlorine content and calorific power are controlled is produced.

回避等の運転管理が難しかった。In a conventional RPF production facility having a single raw material supply line, raw material receiving conditions,
In other words, the calories (calorific value) and chlorine content of the obtained RPF are almost determined by the properties of the waste brought into the facility and the chlorine removal efficiency of the dechlorination device,
The degree of freedom of the product was small. In addition, since the calorie and chlorine content of the product RPF cannot be adjusted, it has not been possible to meet user demands. Further, in the process of dechlorinating waste plastics by heating, thermal decomposition of papers contained in wastes simultaneously proceeded, and the yield of papers was extremely poor.
Furthermore, in addition to dechlorination of plastics, thermal decomposition of papers has occurred, so the exhaust gas from the dechlorination equipment will contain not only hydrogen chloride but also a large amount of organic acids such as acetic acid, A large amount of neutralizing alkali was required in the exhaust gas treatment process. In addition, since the raw material supply line is a single line, there is a limit to the scale-up of equipment, particularly a dechlorination apparatus. Furthermore, since it is a series of operations, it has been difficult to manage operations such as avoiding troubles.
