Abstract
The invention relates to a scale inhibitor and dispersant for a wet process phosphoric acid filter system. The scale inhibitor and dispersant is characterized by comprising the following raw material components in percentage by weight: 5%-15% of organic phosphoric acid, 40%-65% of phosphorus-containing polymer, 25%-40% of sulfonic acid copolymer, 0.05%-0.5% of aluminum slat and 4-10% of water. The adding amount of the scale inhibitor and dispersant is 0.005%-0.02% of wet process phosphoric acid; and the scale inhibitor and dispersant disclosed by the invention can effectively prevent the scale formation phenomenon of the filter system during the production of the phosphoric acid, has no influence on subsequent working sections and has good application prospects.
Description
Technical field
The present invention relates to a kind of dirt dispersion agent, relate in particular to a kind of dirt dispersion agent for the phosphoric acid by wet process filtering system.
Background technology
The dirty main component that vacuum filtering system produces in the Wet-process Phosphoric Acid Production process is Sodium Silicofluoride (potassium) and calcium sulfate.This is because Rock Phosphate (72Min BPL) K in dissolution process
+, Na
+, Ca
2+Deng metal ion and SiF
6 2-, SO
4 2-Due to the precipitable crystallinity salt of formation.Problems such as this type of settling easily concentrates at pump housing, valve etc. and locates in actual production, cause pumping capacity to descend, and instrument valve is out of control occur, and especially can have influence on the filtering rate of phosphogypsum and the continuous production of device.This not only brings very big burden to production, also can cause economically loss because of breaks in production.Ubiquitous problem does not still have effective solution in this Wet-process Phosphoric Acid Production at present.
Summary of the invention
The objective of the invention is provides a kind of dirt dispersion agent for the phosphoric acid by wet process filtering system in order to improve the deficiencies in the prior art, mainly solves the problem of filtering system fouling in the Wet-process Phosphoric Acid Production process.
Technical scheme of the present invention is: a kind of dirt dispersion agent for the phosphoric acid by wet process filtering system, the weight percent that it is characterized in that its feed composition and each ingredients constitute raw material total amount is respectively: a kind of dirt dispersion agent for the phosphoric acid by wet process filtering system, the weight percent that it is characterized in that its feed composition and each ingredients constitute raw material total amount is respectively: organic phospho acid acid 5%～15%, contain phosphine polymkeric substance 40%～65%, sulfonic acid copolymer 25%～40%, aluminium salt 0.05%～0.5%, water 4-10%.
Preferred described organic phospho acid is 2-phosphonate group-1,2,4-butane tricarboxylate, Amino Trimethylene Phosphonic Acid or polyamino polyether base methylenephosphonic acid.
Preferred described phosphorous polymer is hydrolysis phosphino-polymaleic acid, contains phosphine polymaleic acid, phosphono-carboxylic acids or contain the phosphine polyacrylic acid.
Preferred described sulfonic acid copolymer is vinylformic acid/2-acrylamido-2-methyl propane sulfonic acid multipolymer, toxilic acid/2-acrylamido-2-methyl propane sulfonic acid/acrylic copolymer or vinylformic acid/2-acrylamido-2-methyl propane sulfonic acid/Propylene glycol monoacrylate multipolymer.
Preferred described aluminium salt is Tai-Ace S 150, aluminum chloride or aluminum nitrate.
The present invention also provides the preparation method of above-mentioned dirt dispersion agent, its concrete steps are: earlier aluminium salt is dissolved in water by proportioning raw materials, add organic phosphonate more respectively, contain phosphine polymkeric substance, sulfonic acid copolymer, continuously stirring is even then, namely gets the dirt dispersion agent finished product.
Beneficial effect:
1. dirt dispersion agent of the present invention can use under high acidity condition, and main foulant Sodium Silicofluoride (potassium) is had good scale inhibition effect.
2. the preparation method is simple, and is easy to use, and workshop section has no effect to postorder, has a good application prospect.
