Abstract

The invention discloses a U-shaped bottom-hanging type ash and slag melting treatment device. The U-shaped bottom-hanging type ash and slag melting treatment device comprises an ash and slag melting furnace provided with a front vertical hearth and a rear vertical hearth. The wall of the front vertical hearth is provided with flame passages, and a furnace start combustion-supporting combustor is arranged on an outer opening of each flame passage. The wall of the rear vertical hearth is provided with a smoke outlet and a furnace door, and the bottom of the ash and slag melting furnace is provided with a furnace bottom. The bottoms of the front vertical hearth and the rear vertical hearth are communicated through the furnace bottom, and a molten slag overflow passage is arranged at a lowest point of the furnace bottom. A front furnace top covers a feeding port of the front vertical hearth, and the front furnace top is provided with an ash and slag falling passage. A discharging port of a feeding device mounted on the front furnace top is in butt joint with an outer opening of the ash and slag falling passage, a plurality of oxygen blowing branch pipes in an oxygen supply device mounted on the front furnace top enter the front furnace top along a horizontal tangent line, a water-cooling slag extractor is arranged below the furnace bottom, and an inlet of the water-cooling slag extractor is in butt joint with an outer opening of the molten slag overflow passage. The U-shaped bottom-hanging type ash and slag melting treatment device has the advantages of simple structure, convenience in operation, low operational cost and the like.

Description

technical field [0001] The invention relates to the melting treatment of the fly ash produced by the domestic waste incineration treatment system, the fly ash slag produced by the hazardous waste incineration treatment system, and the powdery dangerous substances such as heavy metal sludge, so as to achieve non-toxicity, volume reduction and resource utilization U-shaped hanging bottom ash melting treatment device. Background technique [0002] The fly ash produced during the incineration process of domestic waste, and the fly ash and slag produced during the incineration process of hazardous waste contain a large amount of dioxin-like toxic substances and heavy metals. Some industrial sludge also contains a large amount of heavy metals, which will cause serious harm to the living environment of human beings if they are not properly treated. The most effective and thorough disposal method for the above-mentioned toxic substances is to adopt melting treatment. The above haz...
