METHOD AND DEVICE FOR RECOVERING PURE PVC FROM PLASTIC WASTE CONTAINING PVC |
摘要 |
<p>In a method for recovering pure PVC from pre-disintegrated PVC containing substance mixtures, the substance mixture is soaked in a swelling agent for PVC, is supplied under pressure into an arrangement of at least two sequential hydrocyclones, wherein, in the first hydrocyclone, a heavy fraction of impurities is separated in the sink flow and a light fraction of swelled PVC particles and light impurities and plastic particles are separated in the rising flow, wherein the pre-cleaned light fraction is sorted and the particle fraction comprising the swelled PVC particles and smaller plastic particles is fed to the second hydrocyclone in which the PVC particles are separated in the sink flow. The invention also describes a device for carrying out the method.</p> |
