Abstract
The invention relates to the technical field of the utilization of manganese-containing waste liquid obtained by producing hydroquinone, in particular to a method for preparing co-product of manganese carbonate and zinc sulfate as well as ammonium carbonate by manganese-containing waste liquid obtained by producing hydroquinone. The method mainly comprises the steps of: firstly, leaching the manganese-containing waste liquid obtained by producing hydroquinone by a leaching machine, and obtaining filtrate for distilling and filtering; carrying out deep processing on a filter cake, and obtaining the manganese carbonate product; and then carrying out reduced pressure distillation on the filtrate, respectively carrying out further deep processing, and obtaining the zinc sulfate and the ammonium carbonate. The method leads the waste liquid to be cleanly removed so as to reduce the pollution of the waste liquid for the environment, and can be used for preparing the valuable manganese carbonate, zinc sulfate and ammonium carbonate, thus not only being remarkable in social benefit and economic benefit, but also being simple in technique and production equipment; therefore, the invention is a more practical processing and utilizing method.
Description
Technical field
The present invention relates to produce the technical field that contains the manganese waste water utilization that Resorcinol produces, particularly a kind of with producing the method that the manganese waste liquid is made manganous carbonate co-producing sulfuric acid zinc and volatile salt that contains that Resorcinol produced.
Technical background
Resorcinol is important organic intermediate, and China has also dropped into suitability for industrialized production in the development seventies in 20th century.Advantages such as at present domestic mainly taking used aniline-Manganse Dioxide explained hereafter Resorcinol, and this technology is compared with external phenol-hydrogen peroxide process, has the product purity height, and impurity is few.But its shortcoming is that the quantity discharged of waste liquid is big.Under the common state, one ton of Resorcinol of every production has 40 tons of Mn-bearing waste waters approximately.The chemical composition that contains manganese waste liquid the inside of Resorcinol is the content 11~12% of manganous sulfate, and ammonium sulfate content is 1.4~1.6%, and sulfuric acid content is 1.8~2.2%, simple substance element residue 5~6%.At present domestic factories' utilizations contain the manganese waste liquid and produce crystal manganous sulfate or common carbonate, and high-purity manganese carbonate etc.High-purity manganese carbonate is an ideal high performance strong magneticsubstance, is the main raw material of the manganese-silicon that developed rapidly modern age, mangal, high-performance manganese dioxide product.High-purity manganese carbonate mainly is as soft magnet oxygen magneticsubstance at present, is that raw material is produced with electrolytic manganese or manganous sulfate, bicarbonate of ammonia etc. generally.But do not have a kind of at present with producing the relevant report that the manganese waste liquid is made the method for manganous carbonate co-producing sulfuric acid zinc and volatile salt that contains that Resorcinol produced yet.
Summary of the invention
The invention provides that a kind of this method not only technology is simple with producing the method that the manganese waste liquid is made manganous carbonate co-producing sulfuric acid zinc and volatile salt that contains that Resorcinol produced, and can also make multiple value product when can effectively dispose waste liquid.
To achieve the above object, technical scheme of the present invention is:
A kind of with producing the method that the manganese waste liquid is made manganous carbonate co-producing sulfuric acid zinc and volatile salt that contains that Resorcinol produced, comprise being prepared as follows step:
Steps A, will produce the waste liquid that Resorcinol produces and carry out suction filtration with the suction filtration machine;
Step B, suction filtration gained simple substance residual filter cake in the steps A is used to develop other products;
Step C, suction filtration gained filtrate in the steps A is transferred in the reactor, drops into zinc carbonate solution simultaneously and react, the mass ratio between filtrate and the zinc carbonate solution is 1: 0.63~1.03; Reaction generates the mixture I of manganous carbonate and zinc sulfate and volatile salt;
Step D, the mixture I of gained among the step C is filtered with strainer;
Step e, with filter among the step D gained filter cake through wash drying, crushing packing becomes manganese carbonate product;
Step F, with the clarifying filtrate of sulphur of gained among the step D through underpressure distillation, gradient cooling, crystallization, obtain zinc sulfate crystal and volatile salt crystal respectively;
Step G, with step F gained zinc sulfate crystal through wash drying, crushing packing becomes the zinc sulfate product;
Step H, with step F gained volatile salt crystal through wash drying, crushing packing becomes the volatile salt product.
The present invention carries out suction filtration with the waste liquid that Resorcinol produced with the suction filtration machine earlier, obtains filtrate and carries out distillating filtering, and the filter cake deep processing obtains manganese carbonate product; Further respectively deep processing obtained zinc sulfate and volatile salt product respectively after filtrate was carried out underpressure distillation again; The present invention can as clean as a pennyly gulp down waste liquid, alleviates the pollution of waste liquid to environment; Can make valuable manganous carbonate, zinc sulfate and volatile salt product again, not only have remarkable social benefit and economic benefit, and technology and production unit are simple, be a kind of relatively actual processing and utilize method.
