Description
Technical field
The utility model relates to chemical equipment technical fields, and in particular to a kind of sulfonation reaction device of naphthalene water reducer.
Background technique
Water-reducing agent is a kind of additive with water-reducing effect in concrete, can be improved when not increasing folk prescription water consumption
Execution conditions；Improve the bending and compressive strength of concrete；Enhance the freeze proof performances such as impervious of concrete；It can significantly improve simultaneously mixed
The workability and mobility for coagulating soil, improve the durability of concrete；Or it is essentially identical and do not influence and easily in concrete flowability
Property under the conditions of, reduce coagulation local prescription water consumption, reduce water-cement ratio, save folk prescription gel material content.Water-reducing agent has become existing
For the 5th kind of necessary component other than coagulation earth removal concrete, sand, stone, water.Naphthalene series high-efficiency water-reducing agent be in the world using at most,
The most important water-reducing agent kind of one of most wide water-reducing agent and China.However, most of in naphthalene water reducer used in China
It is low dense naphthalene water reducer.During naphthalene water reducer production, it will usually appropriate more addition concentrated sulfuric acids, in order to make
Sulfonating reaction carries out thorough, to obtain the product of high concentration, general technique be in calcium hydroxide and excessive sulfuric acid,
Using highly concentrated product is obtained by filtration.Make however, excessive sulfuric acid is trapped in naphthalene water reducer product in naphthalene water reducer
Sodium sulphate is generated during calcium hydroxide neutralization reaction, and then causes the sodium sulphate content in final products higher, is substantially reduced
Certain performances of water-reducing agent, such as: weaken the dispersion performance of water-reducing agent；The slump-loss of concrete mix is set to become larger
Deng negative effect.If reducing the dosage of sulfuric acid, i.e., reactant concentration declines, and reacts in the short time and reaches balance, and sulphonation rate is not high,
Influence product quality.And when sulfuric acid dosage is reduced to a certain amount, reaction can hardly carry out.Its principle is that sulfonating reaction is raw
At water make reaction be unfavorable for positive reaction direction carry out.
Currently, the useful Ca of method (OH) of common reduction sodium sulphate content2It neutralizes, reduce sulfuric acid concentration method and object
It manages falling temperature method (referring to patent CN201310025329).However, with Ca (OH)2Although neutralizing available highly concentrated product, after
Continuous work trouble, needs to increase filter plant, solves the problems, such as solid pollution etc., increase the complexity of technique, and improve
The preparation cost of naphthalene water reducer；If the content of last sodium sulphate is reduced using the method for reducing sulfuric acid, in other conditions
In the case where fixation, the reduction of sulfuric acid can be such that the sulphonation rate in the sulfonating reaction stage in naphthalene water reducer preparation process obviously drops
It is low, keep the water-reducing agent product produced unqualified；According to Physical temperature-lowering method, naphthalene water reducer can be wrapped up in precipitation process and is produced
Product, equally exist the risk that filtration difficulty and product preparation efficiency reduce, and operability is not strong.
