<p>PURPOSE:To provide a method and compact equipment for detoxicating and volume-decreasing a chlorine-containing plastic waste which is low in energy consumption. CONSTITUTION:The chlorine-containing plastic waste 2 is subjected to a low temp. dry distillation in a heating oven 4, and a generated decomposed gas is sent to a gas-cleaning chamber 6, and after being cooled by spraying a washing water and also being removed with a gaseous hydrogen chloride by being absorbed in the washing water, the gas is discharged. The oil intermixing in the washing water sprayed to the decomposed gas is removed by a filter 28 and an oil adsorbent. In this way, the furnace to burn the decomposed gas is not only eliminated but also the temp. of the decomposed gas to be cooled and removed with gaseous hydrogen chloride is relatively lowered, so the whole equipment can be composed compactly without necessitating a large cooling capacity.</p> |
