Description
Technical field
The present invention relates to paper pulp and its method field of manufacturing, specifically, being a kind of system of ferronickel slag inorganic fiber paper pulp
Make method.
Background technique
In recent years, China's ferronickel slag annual emissions surpass 30,000,000 tons, it has also become China is after scum, steel slag, red mud
Four big metallurgical slags.A large amount of ferronickel slags can only be handled as waste, pile up processing or deep-sea landfill, not only land occupation, pollution ring
Border, the sustainable development for returning nickel-iron smelting bring severe challenge.
It is counted according to Chinese papermaking association, 79,490,000 tons of China's pulp production amount in 2017 increases by 0.30% on a year-on-year basis.It is wherein wooden
10,500,000 tons are starched, increases by 4.48% on a year-on-year basis；63,020,000 tons of secondary stock, 0.43% is reduced on year-on-year basis；5,970,000 tons of non-wood pulp increases on year-on-year basis
Long 1.02%.It goes into operation although the country has part to increase wood pulp production capacity newly, compares huge market demand, China's wood pulp production capacity is still
It is unable to satisfy demand, relies primarily on import.
The country ferronickel slag overwhelming majority is technical process of the laterite in electric furnace reduction melting ferronickel of humic soil type at present
Middle generation, main component is FeO, MgO and SiO2, submember is Al2O3、Cr2O3, CaO etc., belong to FeO-MgO-SiO
Ternary slag system.
China's paper product demand is huge, and raw material of wood pulp supply is much insufficient, oneself production chemical pulp wastes a large amount of water moneys
Source, and cause the pollution of serious environment.Because of a kind of ferronickel slag inorganic fiber paper pulp of the invention, as ferronickel slag must be comprehensively utilized
New way is had found, and reduces paper product cost, save timber, the wasting of resources is reduced, protects environment.
