Abstract

The invention discloses a heat storage ash melting device, comprising a furnace body; the upper half part of the furnace body is a cylindrical upright furnace body; the lower half part of the furnace body is a box furnace body; the whole box furnace body is in a structural mode with a higher rear part and a lower front part. A cylindrical upright hearth is arranged in the cylindrical upright furnace body, a retracing horizontal hearth is arranged in the box furnace body; a heat storage ash melting bed is arranged in the retracing horizontal hearth; a furnace top cover is arranged above the cylindrical upright furnace body; a feeder and an oxygen supply device are arranged on the furnace top cover; two furnace starting combustion supporting burners are arranged at the rear wall of the cylindrical upright furnace body; two temperature control burners are arranged on a furnace arch of the box furnace body; a round cork furnace door and a fume outlet are arranged on the front wall and rear wall of the box furnace body respectively; a slag discharge port is formed in the furnace bottom of the box furnace body and is jointed with a water cooling slag extractor. The heat storage ash melting device is an ash melting technology with high adaptive capacity, good operation benefits and capability of ensuring ash melting quality.

Description

technical field [0001] The invention relates to a heat storage bed type ash melting device which melts fly ash and slag of hazardous waste, and dried heavy metal sludge and other powdery materials to achieve non-toxicity, capacity reduction and resource utilization. Background technique [0002] The fly ash and slag of hazardous waste, especially the heavy metal sludge, have obvious differences in composition, and have different requirements for conditions such as melting temperature and melting mixing time. The current melting unit cannot meet the requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a heat storage bed type ash melting device with strong adaptability and good operating efficiency for ensuring the quality and effect of ash melting. Using the heat storage bed type ash melting device to treat all kinds of heavy metal sludge can form stable vitreous slag that meets the non-toxic discharge s...
