Treatment method and device of waste resource

摘要

A waste resource treatment method and device include pyrolysis desorption treatment elements having one or more pyrolysis desorption chambers connected in parallel. Sub-temperature fractionation treatment elements having a low-temperature fractionating pipe and a plurality of higher-temperature or high-temperature fractionating pipes for fractionating a gas at different temperature ranges are connected to the pyrolysis desorption chambers, respectively. The fractionating pipes are connected to sub-temperature resource recycling treatment elements for treating the gas at different temperature ranges, respectively. The sub-temperature resource recycling treatment elements are connected to refrigeration-liquefaction treatment elements and to adsorption exhaust treatment elements. The gas produced at different temperature ranges during a heating process performed inside the pyrolysis desorption chambers undergoes a resource recycling treatment and then is collected by refrigeration-liquefaction, and eventually undergoes adsorption exhaust treatment, such that various hazardous substances are sorted before applying to a resource application or undergoing further treatment.
