NOVELTY - Clean energy device comprises a heating chamber for supplying heat energy to the subsequent devices. The heating chamber is connected to a gas converter, where the gas converter is connected with a gas deacidification tower and a cracking reactor. The cracking reactor converts the waste into mixed gas and carbides. The cracking reactor is connected to a slag collector which collects slag produced by cracking reactor. The mixed gas and carbides were passed into the gas converter for high temperature anaerobic carbonization treatment resulting in combustible gas and carbon black.    USE - The clean energy device is useful for domestic waste (claimed).    ADVANTAGE - The device is environmentally-friendly, utilizes natural gas as to supply heat or generate power without secondary pollution.    DETAILED DESCRIPTION - Clean energy device comprises a heating chamber for supplying heat energy to the subsequent devices. The heating chamber is connected to a gas converter, where the gas converter is connected with a gas deacidification tower and a cracking reactor. The cracking reactor converts the waste into mixed gas and carbides. The cracking reactor is connected to a slag collector which collects slag produced by cracking reactor. The mixed gas and carbides were passed into the gas converter for high temperature anaerobic carbonization treatment resulting in combustible gas and carbon black. The gas deacidification tower carries out deacidification of the combustible gas. The gas deacidification tower is connected to a gas purification tower for further purification of combustible gas to obtain industrial gas. The gas purification tower is set with a gas storage tank storing purified combustible gas. An INDEPENDENT CLAIM is also included for waste disposal method using clean energy device, comprising converting waste into mixed gas and carbides by cracking reactor, passing the mixed gas and carbides into the gas converter, where the gas converter carry out anaerobic high temperature carbonization treatment, resulting in combustible gas and carbon black, the gas deacidification tower carries out deacidification of the combustible gas to obtain industrial gas.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the clean energy device for domestic waste.
