Abstract
The invention relates to the field of barium chloride production technologies, in particular to a technology for a solid barium chloride acidification section. The technology comprises steps as follows: witherite is smashed by a smasher, and large-grained barium powder is placed in water for soaking to the pasty state; the well soaked slurry is pumped into an acidification tank by a slurry pump, and a certain amount of hydrochloric acid with the concentration of 31% is added regularly and rapidly stirred for an acidizing reaction; after acidification is completed, a solution is added to a neutralizer, a caustic soda solution with the concentration of 31% is added to the neutralizer for a neutralization reaction, and magnesium ions and iron ions are removed; after neutralization, a neutralizing solution is fed into a settling tank, and large-grained substances are removed; supernatant in the settling tank is fed into a plate and frame filter for filtration, obtained filtrate is sent to an evaporative crystallization section for evaporative crystallization, and a final product is obtained. The technology for the solid barium chloride acidification section has low cost, and H2S pollution cannot be caused.
Description
Technical field
The present invention relates to barium chloride production technology field, specifically a kind of solid chlorine barium acidification of acidification section technique.
Background technology
Inorganic chemicals industry is a composition department of chemical technology, has the features such as wide in variety, purposes is wide, production method is various.At present, the inorganic salt kind of produced worldwide is about left and right in 1300.And some inorganic salt product, because industrial scale is large, develop into independently industrial sector, as sulfuric acid and nitric acid industry, basic industry and chemical fertilizer industry etc.Bariumchloride belongs to the one of product in inorganic chemicals industry, and China's barium ore resources enriches, and it is predicted that resource total reserves will more than 1,000,000,000 tons, and barium ore deposit grade is higher, barium ore reserves and the current Jun Ju world of output the first, be the favourable condition of development barium salt.Current production bariumchloride raw material many employings barite substantially, cost is high, can produce H2S pollution problem.Utilize witherite to produce barytic operational path and have the extremely strong market competitiveness, will develop rapidly from now on, become and produce the most general method of bariumchloride.
Summary of the invention
For the deficiency of above-mentioned traditional processing technology, the invention provides a kind of solid chlorine barium acidification of acidification section technique.
Technical scheme of the present invention is as follows: a kind of solid chlorine barium acidification of acidification section technique, comprises the following steps:
A. witherite is pulverized through pulverizer, then oarse-grained barium powder is put into water and soak, reach pastiness;
B. the slip soaked is driven into souring tank through shurry pump, and the hydrochloric acid adding a certain amount of 31% concentration of timing, rapid stirring, makes generation acidification reaction;
C. after acidifying completes, added by solution in neutralizer, the caustic soda soln adding 31% concentration in neutralizer carries out neutralization reaction, removing magnesium ion and iron ion;
D. in and after, neutralizer is sent into subsider, removes large particulate matter;
E. the supernatant liquor in subsider is sent into flame filter press to filter, the filtrate obtained is delivered to evaporative crystallization workshop section and carries out evaporative crystallization, namely obtain last product.
Powdered breeze and hydrochloric acid reaction rapidly, can produce a large amount of bubble, and therefore will guarantee that the concentration of hydrochloric acid is wanted precisely, interpolation speed will be suitable for.
Advantage of the present invention: the invention provides a kind of solid chlorine barium acidification of acidification section technique, cost is low, does not produce H2S and pollutes.
Accompanying drawing explanation
Fig. 1 is process flow diagram of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As Fig. 1, a kind of solid chlorine barium acidification of acidification section technique, comprises the following steps:
A. witherite is pulverized through pulverizer, then oarse-grained barium powder is put into water and soak, reach pastiness;
B. the slip soaked is driven into souring tank through shurry pump, and the hydrochloric acid adding a certain amount of 31% concentration of timing, rapid stirring, makes generation acidification reaction;
C. after acidifying completes, added by solution in neutralizer, the caustic soda soln adding 31% concentration in neutralizer carries out neutralization reaction, removing magnesium ion and iron ion;
D. in and after, neutralizer is sent into subsider, removes large particulate matter;
E. the supernatant liquor in subsider is sent into flame filter press to filter, the filtrate obtained is delivered to evaporative crystallization workshop section and carries out evaporative crystallization, namely obtain last product.
Powdered breeze and hydrochloric acid reaction rapidly, can produce a large amount of bubble, and therefore will guarantee that the concentration of hydrochloric acid is wanted precisely, interpolation speed will be suitable for.
The invention provides a kind of solid chlorine barium acidification of acidification section technique, cost is low, does not produce H2S and pollutes.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
