Problems solved by technology

[0005] However, there is currently no targeted melting furnace for processing by-product industrial salt
When using the existing rotary kiln, vertical incinerator, horizontal incinerator, box furnace, fluidized bed incinerator to carbonize the inorganic salt, due to the inorganic salt in the molten state and the high temperature furnace wall In direct contact, there will be a phenomenon of "sticking to the wall", which will not only affect the normal carbonization of inorganic salts, but also shorten the service life of the equipment
[0006] More importantly, since the existing melting furnaces use ordinary refractory bricks, they are not suitable for the treatment of by-product industrial salt, especially the problems of severe corrosion and serious precipitation of metal ions during the melting process of by-product industrial salt, and Formed sediment residue is difficult to clean up

Description

technical field [0001] The invention relates to the technical field of by-product industrial salt treatment equipment, in particular to a by-product industrial salt melting furnace that reduces the precipitation of metal ions. Background technique [0002] At present, the by-product industrial salt contains a small amount of organic matter, which is difficult to be effectively treated and utilized, and cannot be directly used as a raw material for downstream products. Most manufacturers can only stockpile it or send it to a solid waste treatment center for processing. At present, the treatment cost of the solid waste treatment center is as high as 3,000-4,000 yuan / t, which is unbearable for enterprises, and the landfill is mainly treated with anti-corrosion and anti-seepage treatment before landfilling. This treatment method not only occupies land, but is also a great waste of resources, and there is a potential risk of posing a huge threat to the environment. Once the anti...
