Description
Technical field
The present invention relates to by-product Nacl processing technology field, more particularly to by-product industry salt treatment melting furnace and place
Reason method.
Background technology
At present, by-product Nacl is because containing a small amount of organic matter, it is difficult to is effectively addressed and utilizes, it is impossible to directly as under
Swim the raw material of product.Fixed-end forces center processing can only be stored up or be delivered in most of manufacturer.At present in fixed-end forces
The processing cost of the heart is up to 3000-4000 members/t, and enterprise is difficult to bear, and main use takes anti-corrosion leak-proof to handle landfill yard
The processing mode filled again afterwards.This processing mode not only land occupation, while be also the significant wastage to resource, is also present pair
Environment causes the potential risk of grave danger, once anti-corrosion leak-proof layer leaks, soluble-salt and organic impurities are lost from,
Salinization surrounding soil, surrounding vegetation is endangered, while periphery water source, underground water and farmland are polluted.
By-product Nacl is important Elementary Chemical Industry raw material, and extremely valuable national strategy resource.As its people pass through
The high speed development of Ji, various by-product Nacl amounts are increasing in Chemical Manufacture, to environment structure grave danger.In recent years, people
Resources conservation, environment-friendly understanding are stepped up, government there has also been notable reinforcement in environmentally friendly legislation and law enforcement dynamics,
The processing of by-product Nacl and recycling are increasingly subject to pay attention in Chemical Manufacture.
As Patent No. CN201310184084.4, it is entitled " in a kind of industrial wastewater the extracting method of inorganic salts and
The utility model patent file of the resource utilization method of industrial wastewater ", and Patent No. CN201310299546.7, practicality
New Name is the utility model patent file of " a kind of method that high purity inorganic salt is reclaimed from phosphorous industrial wastewater ",
Disclose from industrial wastewater reclaim inorganic salts method, in order to obtain high purity inorganic salt most afterwards through carburising step at
Reason, to remove the organic impurities in inorganic salts.
But the melting furnace for targetedly handling by-product Nacl not a kind of at present.Utilize existing rotary kiln, vertical
Incinerator, horizontal incinerator, batch-type furnace, fluidized bed furnace, grate incinerator or fluidized bed incinerator carry out charing process to inorganic salts
When, because the inorganic salts of molten condition directly contact with high-temperature kiln wall, there can be " viscous wall " phenomenon, not only influence inorganic salts just
