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 t...

Abstract

The invention discloses a by-product industrial salt melting furnace having an effect of reducing precipitation of metal ions. The furnace chamber main body of the by-product industrial salt melting furnace has a heating chamber and a melting chamber. The refractory bricks of the heating chamber are prepared from 20 to 25 parts by weight of mullite powder, 30 to 35 parts by weight of silicon carbide powder, 10 to 15 parts by weight of silica powder, 20 to 25 parts by weight of alumina micro-powder, 10 to 15 parts by weight of forsterite micro-powder, 5 to 10 parts by weight of vermiculite micro-powder, 15 to 25 parts by weight of quartz micro-powder, 10 to 20 parts by weight of zirconite micro-powder and 7 to 15 parts by weight of sillimanite micro-powder. The refractory brick of the melting chamber is prepared from 30 to 35 parts by weight of silicon nitride micro-powder, 20 to 25 parts by weight of silicon carbide micro-powder, 10 to 20 parts by weight of silica powder, 7 to 15 parts by weight of boron carbide micro-powder and 20 to 25 parts by weight of silica sol. The furnace can reduce metal ion precipitates produced by melting of a by-product industrial salt.

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...
