Abstract
The invention relates to a preparation method of a hydrochloric acid concentration osmosis film. The preparation method includes: modifying a polyvinylidene fluoride (PVDF) thin film by using trifluoromethyl sulfinyl chloride, methylsulfonyl fluoride, methyl pyrrolethioketone, 1-ethyl-3-methylimidazole bis(trifluoromethyl sulfonyl) imide.
Description
Technical field
The present invention relates to the preparation method of a kind of film, the preparation method of a kind of hydrochloric acid concentration permeable membrane.
Background technology
One of application of membrane separation technique is to recycle spent acid spent lye.Along with modern industry (iron and steel, smelting
Gold, papermaking etc.) development, production process produce mineral acid alkali liquor be also continuously increased, the extraction process of such as metallic ore
In employ substantial amounts of alkaline solution, a large amount of spent lye containing metallate ion can be produced.If these spent lyes do not have
It is suitable to do, and not only the useful resources in waste liquid can not get reasonably recycling, but also can cause environment and water source, biology
The most serious infringement.The most how these spent acid spent lyes are carried out cost-effective process, be that there is theory significance very much
Research topic with using value.
CN102285641A relates to a kind of recycling process of waste hydrochloric acid, it is characterised in that: after waste hydrochloric acid is by preheating, with preparation
The good calcium chloride solution as catalyst is sufficiently mixed, and enters hydrochloric acid desorber, and the reboiler bottom hydrochloric acid desorber is made
Using lower precipitation, the hydrogen chloride gas of precipitation collects after subcooler and demister, dissolved with a small amount of hydrogen chloride water again
It is back to hydrochloric acid desorber continue to resolve, is then passed through flash distillation diversion cans as the calcium chloride solution of catalyst and carries out preparing profit again
With.Avoid the waste of hydrogen chloride, also reduce cost of sewage disposal.
Hydrochloric acid waste water device and the method reclaiming hydrochloric acid waste water are reclaimed in CN103922529A low energy consumption.This device includes
Cooling absorber 5, water stream injection pump 6, and be sequentially connected waste acid pot 1, triple effect evaporator 2,2nd effect evaporator 3, imitate hydrochloric acid
Desorption tower 4, described cooling absorber 5 is connected with described 2nd effect evaporator 3, described water stream injection pump 6 and described triple effect evaporator 2 phase
Even.The present invention is only passed through 0.3MPa steam, then an effect hydrochloric acid desorption tower in an effect heating chamber 42 of an effect hydrochloric acid desorption tower 4
The water vapour of the containing hydrogen chloride steamed in 4 is as the thermal source of 2nd effect evaporator 3, the water of the containing hydrogen chloride of same 2nd effect evaporator 3
Steam is again as the thermal source of three vaporizers 2.
Hydrochloric acid concentration technology of the prior art is with evaporation, distillation, and extractive distillation is main, has energy consumption high, long flow path
Shortcoming, in the urgent need to new extracting and concentrating technology to improve efficiency, reduces energy consumption.Electrodialysis methods can only be by 1-5%(wt%) dilute salt
Acid is concentrated to 10%(wt%) hydrochloric acid of left and right, existing diffusive dialysis method and relate to the osmosis concentration technology of film and can only be concentrated to
10%(wt%) the hydrochloric acid of left and right, it is impossible to further concentration.
Summary of the invention
Present invention aim at solving above-mentioned technical problem present in prior art, it is provided that a kind of hydrochloric acid concentration permeable membrane
Preparation method.It is characterized in that preparation process includes:
By weight, by 100 parts of sulfonated polyether sulfone thin film, double 18 alkyl dimethyl ammonium chlorides of 1-5 part, 100-500 part dicarboxyl
Biphenyl sulfone, 1-5 part dichloroethanes, 0.01-0.1 part 1-carboxyethyl-3-methylimidazolium nitrate, 40-80 DEG C is soaked 10-40h,
Pull out and dry, obtain permeable membrane.
Described sulfonated polyether sulfone thin film is commercially available prod, the product developed such as Hangzhou Xiaoshan Jiang Cheng Chemical Co., Ltd.；
Described 1-carboxyethyl-3-methylimidazolium nitrate is commercially available prod, such as the product of Chinese Academy of Sciences's Lanzhou Chemical Physics Research Institute
Product.
Described dicarboxylate biphenyl sulfone, double 18 alkyl dimethyl ammonium chlorides are commercially available prod.
Due to the fact that and have employed technique scheme, have the advantages that
Sulfonated polyether sulfone thin film is through double 18 alkyl dimethyl ammonium chlorides, dicarboxylate biphenyl sulfone, 1-carboxyethyl-3-Methylimidazole. nitre
The modification of hydrochlorate, is improved the permeance property of hydrochloric acid, 1-5%(wt%) dilute hydrochloric acid can be concentrated to obtain quality hundred
The proportion by subtraction concentration hydrochloric acid higher than 20%.
