Description

Purifier apparatus and the purifying process of abraum salt in a kind of glyphosate by product
Technical field
The present invention relates to the purifier apparatus of abraum salt in a kind of glyphosate by product, and utilize this equipment to carry out purifying to abraum salt, belong to the chemical field of glyphosate production.
Background technology
Glyphosate is a kind of good organic phosphates nonselective herbicide, it is the natural disposition highy potent herbicide that goes out after the bud of a kind of efficient, low toxicity, low residue, broad weed-killing spectrum, consumption maximum in the Ye Shi world today, one of weedicide kind of the most violent also tool market competitiveness of growth, this kind emerges rapidly along with the spread of global genetically modified crops at present.
China is current glyphosate production state and the export State of maximum in the world, and within 2013, national glyphosate output reaches 800,000 tons.And in the waste water producing in the production of glyphosate, sodium-chlor is wherein important integral part, and in average 1 ton of mother liquor, sodium chloride content is 15%, can produce 6 tons of waste water and produce 1 ton of glyphosate, calculate like this, annual domestic glyphosate industry produces sodium-chlor abraum salt and is about 900,000 tons.Along with domestic glyphosate industry constantly increases the dynamics of efforts at environmental protection, the processing requirements of a large amount of industrial waste salts is also more and more higher, first glyphosate industry inherence is upper to the industrial waste salt processing in mother liquor is at present generally the mode by evaporative crystallization, abraum salt is extracted from mother liquor, because this salt contains more organism and ammonia nitrogen impurity, poor quality, cannot directly use, therefore most of glyphosate production producer all takes following two kinds of methods to process abraum salt again: the one, and directly outer selling, the 2nd, landfill after calcination, but all there is certain defective workmanship in these two kinds of methods in actually operating, have a strong impact on the production development of the environmental protection of glyphosate industry.
1. direct outer selling:
The abraum salt extracting, mode with solid waste is directly externally sold, main application is Snow Agent, this treatment process seems simply concerning enterprise, but added value is low, deficiency in economic performance, and Snow Agent is used and is subject to seasonal effect, market is unstable, very easily causes overstockedly, affects the normal production order of enterprise.
2. landfill after calcination
First abraum salt is passed through to boiler calcination, the organic impuritys such as the ammonia nitrogen in removal abraum salt, then dig Di Chi and carry out landfill.This method need consume more fuel, and processing cost is very high, and in fact this method can only be calculated temporary instead of process simultaneously, and problem is at the moment put off backward.Along with the time constantly increases, enterprise will consume more fund and increasing abraum salt is kept in soil, and this method is a kind of unsustainable Development patterns.
Summary of the invention
For overcoming above defective workmanship, our company utilizes sodium-chlor and the impurity characteristic very large to the difference in solubility of saturated brine in abraum salt, with pure water as washing composition, through multistage washing, effectively remove the impurity in abraum salt, reasonably optimizing product processes, realizes after abraum salt is processed and is applied to production chlor-alkali.Specific as follows:
