METHOD OF AND APPARATUS FOR DISPOSING OF COOLING UNITS |
摘要 |
<p>The invention relates to a method and plant for the disposal of partialy dismantled refrigerators, especially for the disposal of chlorofluorocarbon-containing polyurethane foam. …<??>The partly dismantled refrigerators are introduced into a disposal plant which can be sealed gas-tight, can be operated under a vacuum and can be evacuated at a number of points, and comminuted in a comminution plant. The materials adhering to the PUR foam are mechanically separated off. The residue-free PUR foam is ground to a powder, the cells of the PUR foam being destroyed and the bound chlorofluorocarbon-containing blowing gas being released. …<??>The residues and PUR powder are collected separately, and the chlorofluorocarbon-containing gas obtained on comminution and grinding is liquefied. …<??>The advantages achieved by the invention are especially that the disposal of the refrigerators supplied is complete, more than 99% of the chlorofluorocarbon-containing gas being liquefied and recycled together with the other recovered materials. …<IMAGE>… </p> |
