Abstract
Description
Technical Field
[0001] This utility model relates to incineration fly ash treatment technology, and in particular to a device for efficient molding of low-humidity fly ash solidified body. Background Technology
[0002] With the increasing adoption of waste incineration technology both domestically and internationally, the amount of fly ash produced is also increasing. Incineration of municipal solid waste generates approximately 25% slag and 3%–5% fly ash by weight. Fly ash contains heavy metals such as Mn, Mg, Sn, Cd, Pb, and Cr, as well as dioxins and other organic compounds, and is classified as hazardous waste. Its safe disposal is receiving growing attention both domestically and internationally.
[0003] Currently, fly ash from waste needs to be mixed with a solidifying agent (chelating agent) for stabilization before landfilling to prevent the leaching of heavy metals from the interior into the environment. However, the apparent volume of the solidified fly ash obtained by existing technologies is still relatively large, with a low bulk density. It is prone to dust generation during transportation and landfill disposal, and occupies a large amount of space in landfills, resulting in low space utilization.
[0004] The current method for reducing the volume of fly ash solidified body is to press the fly ash solidified body into bricks by stamping. However, the fly ash solidified body may have low local moisture content due to insufficient mixing, which can cause delamination during the stamping process and make it difficult to form, seriously affecting the volume reduction effect of fly ash solidified body.
[0005] It should be noted that the information disclosed in the above background section is only used for understanding the background of this utility model, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
