Dehydrator waste bin, heat resistant perforated bin bag and a thermal pre-treatment process to remove moisture from mixed municipal solid waste

摘要

A waste bin thermally treats solid waste with air above 70 degrees C. The bin can receive waste in the production place and the hot air can evaporate the moisture to dehydrate it. Excess moisture can be removed by gravity 18 through perforations in a heat resistant bin bag 1 to a holding removable tank 2 located in the base. The hot air and water vapour will preferably be re-circulated 3 until the hot air has values near to the saturation point after which water is condensed out into the tank. Finally, hot air from the heat exchanger can pass through a filter 10 to remove contaminants and reduce the odours before release 11 into the environment. Dehydrated waste may be removed from the bin by extracting the perforated bin bag 1. A new heat resistant perforated bin bag 1 could then be placed into the bin to receive new waste for treatment.
