Abstract
The invention belongs to the technical field of three-waste treatment and comprehensive utilization of inorganic chemical industry, in particular relates to a method for preparing precipitated barium sulfate coproduced with hydrochloric acid by using barium mud. The method mainly comprises the following steps of: reacting the barium mud with hydrochloric acid, filtering to obtain filtrate, reacting the obtained filtrate with sulfuric acid to obtain a filter cake, washing, dripping, drying and crushing the filter cake, weighing and packaging to obtain a precipitated barium sulfate product. By utilizing the method, the barium mud residues can be thoroughly removed so as to lighten the pollution of the barium mud residues to the environment; the valuable precipitated barium sulfate product can be prepared; especially in the production process, the obtained hydrochloric acid can be recycled; and therefore, the method disclosed by the invention not only has remarkable social and economic benefits, but also has simple process and production equipment and is a more practical treatment and utilization method.
Description
Technical field
The invention belongs to the technical field of the inorganic chemical industry disposal of three wastes and comprehensive utilization, particularly a kind of with the clay method that is equipped with the process white co-production of hydrochloric of barium.
Technical background
Barium salt is a kind of that purposes is wide in the inorganic salts product, output is bigger, but no matter is bariumchloride, barium carbonate, or the production of barium sulfate, all will produce a large amount of body refuses inevitably---barium mud; And quantity discharged is very big, produce 20000 tons of barium carbonates per year for one, the factory of eight kiloton barium sulfate, at least need to discharge useless barium mud (butt) four kilotons every year, barium slag (butt) eight kilotons, owing to contain small amounts of water soluble barium or solubility in acid barium in the barium mud more, as not handling, both wasted the barium resource, the while is serious environment pollution also.Chinese patent application number is 93117305.1 document, having announced the method for a kind of barium mud co-producing sulfuric acid barium, magnesiumcarbonate, refined salt or ammonium chloride, Ba brick and other product, mainly is with the barium mud that is rich in bariumchloride and the halogen wadding (all being waste material) and other raw material co-producing sulfuric acid barium, magnesiumcarbonate, refined salt or the ammonium chloride that are rich in sal epsom.Other is water-soluble with being rich in, the barium mud of solubility in acid barium thing and organic acid, solubility organic acid salt, mineral acid, solubility inorganic acid salt, soda ash, caustic soda, lime-kiln gas, liming reaction also can be produced various organic and inorganic barium salts, barium thing.Though this method is handled filter residue certain effect, complex manufacturing are arranged.The clay relevant report that is equipped with the method for process white co-production of hydrochloric of present barium also of no use.
Summary of the invention
The invention provides with the clay method that is equipped with the process white co-production of hydrochloric of barium, this method not only technology is simple, and can also make multiple value product when can effectively handle waste residue.
To achieve the above object, technical scheme of the present invention is:
A kind of with the clay method that is equipped with the process white co-production of hydrochloric of barium, comprise being prepared as follows step:
Steps A, with barium mud by pure barium sulfate, put in first corrosion-resistant reactor with pure mass ratio 1: 0.17～0.57 with hydrochloric acid and to stir, reaction generates the mixing solutions of bariumchloride, carbonic acid gas and water;
Step B, gained mixing solutions in the steps A is filtered with first strainer;
Step C, send to and burn or buried filtering the gained filter cake among the step B;
Step D, drop into successively in second corrosion-resistant reactor with pure mass ratio 1: 0.27～0.47 with sulfuric acid and stir reaction generation process white and hydrochloric acid mixed solution filtering gained filtrate among the step B;
Step e, gained mixing solutions among the step D is filtered with second strainer;
Step F, the white filter cake that filters gained in the step e washed to check the weight after dryings, drying and the pulverizing with washing and spin-drying machine, moisture eliminator and pulverizer successively be packaged to be the process white product.
Wherein, the filtrate that filtration obtains in the described step step e is returned in first corrosion-resistant reactor and is recycled.
Reaction principle of the present invention is:
BaCO
3+2HCl＝BaCl
2+CO
2+H
2O
BaCl
2+H
2SO
4＝BaSO
4+2HCl
Contain solubility in acid barium salt (in barium sulfate) in the barium mud and be respectively about 50%, 30%, so the barium mudstone is made the good raw material source of barium compound.The present invention mainly is that barium mud and hydrochloric acid react in elder generation, filters, and then gained filtrate and sulfuric acid react, and the gained filter cake is checked the weight through washing drying, drying with after pulverizing and is packaged to be the process white product; The present invention can as clean as a pennyly gulp down barium mud waste residue, alleviates the pollution of barium mud waste residue to environment; Can make valuable process white product again, especially in the production process, the hydrochloric acid that is produced can also recycle, and not only has remarkable social benefit and economic benefit, and technology and production unit are simple, are a kind of relatively actual processing and utilize method.
