Household garbage incineration slag treatment system

The invention discloses a household garbage incineration slag treatment system. The system comprises a combustion device, a gas combustor and a cleaner, wherein a pretreatment area and a melting area are arranged in the combustion device; the pretreatment area can be used for heating and cutting household garbage to be treated, and the melting area can be used for melting metal materials and separating non-metal materials from the metal materials in a molten state; the combustion device is used for enabling gas which is not fully combusted and generated in the household garbage treatment process to enter the gas combustor, and the gas is mixed with fuel gas to be combusted again; and mixed gas combusted in the gas combustor enters the cleaner to be mixed, atomized and cleaned. Compared with the prior art, according to the technical scheme, the household garbage can be reliably treated, and effective treatment of combustion gas can be guaranteed. 本发明公开一种生活垃圾焚烧炉渣处理系统，包括内部设有预处理区域和熔融区域的燃烧装置、气体燃烧器以及清洗器；预处理区域可对待处理的
