Abstract
A kind of production method of Chemicals white carbon black is utilized carbonic acid gas and water glass reaction in the stack gases, the sulfuric acid or the hydrochloric acid that replace traditional precipitator method to use, and can reclaim yellow soda ash, reduced material consumption, alleviated cost, the quality product that its method is produced is all above every index of traditional precipitator method.
Description
The invention belongs to a kind of production method of Chemicals white carbon black.
White carbon black, chemistry hydrated SiO 2 by name, traditional mode of production has two kinds of the precipitator method, vapor phase processs, and precipitationization is to use water dissolution again after yellow soda ash and silicon-dioxide are inserted the high temperature fusion, with sodium silicate solution filter, in and gelling, acidifying, aging, filter, washing, drying is pulverized.Gas phase rule silicon tetrachloride is a raw material, carries out combustion decomposition, and hydrolysis is assembled, and workshop sections such as depickling finish.
The production method that the purpose of this invention is to provide a kind of optimised process road replaces tradition used sulfuric acid or hydrochloric acid with the carbonic acid gas in the flue, and recovery yellow soda ash reaches the reduction material consumption, the minimizing cost.
White carbon black gas-liquid phase working system of the present invention, be to realize like this, it is constant that original yellow soda ash and silicon-dioxide merge workshop section, with conduit stack gases is picked out, by being pressed into carbonating tower behind the gas washing groove, with sodium silicate solution, carbonization, promptly generate white carbon black, the press filtration of back workshop section, washing, drying, disintegrating process is constant, its for the first time pressing filtering liquid be used for diluting water glass, the content that recycles back yellow soda ash repeatedly improves constantly, reach finite concentration after, evaporate, dry be yellow soda ash, can be used to merge silicon-dioxide again.
The concrete processing sequence of implementing: stack gases → gas washing groove → carbonization (adding sodium silicate solution) → press filtration (filtrate is reclaimed after being used to earlier dilute water glass) → washing → drying → pulverizing.
White carbon black gas-liquid phase working system of the present invention, because of having utilized the carbonic acid gas in the flue, the sulfuric acid or the hydrochloric acid that replace traditional precipitator method to use, production cost decreases, simultaneously because of reclaiming yellow soda ash, then further reduce production cost and reduced the quantity discharged of CO 2 waste gas, helped environmental protection.
Its quality product is all above the index of traditional precipitator method.
Claims (2)
1, a kind of gas-liquid phase working system of Chemicals white carbon black is characterized in that, reacts the sulfuric acid or the hydrochloric acid that replace tradition to use with carbonic acid gas in the stack gases and water glass.
2, method according to claim 1 is characterized in that, in process of production, byproduct yellow soda ash is reclaimed.
