Abstract
The invention discloses a liquid superphosphate active porous agent, and belongs to the technical field of production of superphosphate. The liquid superphosphate active porous agent comprises a surface active agent, a dispersing agent, a polymerization inhibitor and water. Once the liquid superphosphate active porous agent disclosed by the invention is used for producing superphosphate, the available phosphorus in fresh fertilizer is increased by 0.5 to 1.0%, the water content is reduced by 1 to 2%, the conversation rate of the available phosphorus is increased by 3 to 7%, the frequency of turning in curing is reduced, and 4 to 10 days in curing are reduced. The liquid superphosphate active porous agent is convenient to use, original production processes of the phosphatic fertilizer are remained, and remarkable economic and social benefits are brought.
Description
Technical field
The invention belongs to the Production of Single Superphosphate technical field, be specifically related to a kind of liquid calcium superphosphate active and porous agent.
Background technology
China is maximum in the world calcium superphosphate consumption market, and phosphate fertilizer production reached 1,100 ten thousand tons in 2005, and phosphate fertilizer will reach 1,270 ten thousand tons in 2015, wherein be calcium superphosphate more than 40%.In Production of Single Superphosphate, a difficult problem that perplexs for a long time enterprise is: product water content control is unstable, and the product caking is serious, turning often, the curing time is long; Slaking storehouse area is excessive, and the gas of uncontrollable discharge can't be processed, and environmental pollution is serious, and these cause product available phosphorus low conversion rate, production process discontinuous, and rework rate is high, the problem such as the higher and economic benefit of enterprise's production cost is low.
Summary of the invention
The object of the present invention is to provide a kind of liquid calcium superphosphate active and porous agent, when adopting liquid calcium superphosphate active and porous agent ssp dnae in next life of the present invention, available phosphorus improves 0.5 ~ 1.0% in its bright fertilizer, moisture content reduces by 1 ~ 2%, the available phosphorus transformation efficiency improves 3 ~ 7%, reduce slaking turning number of times, the curing time shortens 4 ~ 10 days.This product is easy to use, need not to change original production of phosphate fertilizer flow process, possesses significant economic and social benefit.
For achieving the above object, the present invention adopts following technical scheme:
A kind of liquid calcium superphosphate active and porous agent is comprised of tensio-active agent, dispersion agent, stopper and water.
Described tensio-active agent is sodium lauryl sulphate, and dispersion agent is Sodium dodecylbenzene sulfonate or Sodium hexametaphosphate 99, and stopper is ethanol or kerosene.
Each component content is tensio-active agent 6 ~ 20wt%, dispersion agent 30 ~ 40wt%, stopper 3 ~ 5wt%, and surplus is water.
Wet method (ore pulp concentrated acid method) calcium superphosphate production process is by following three reactions steps:

Corresponding technical process is for mixing-change into-slaking.
Can find out from technical process and reactions steps: the tiny thickness calcium sulphate crystal that reaction formula (1) produces covers on the breeze face, stops its reaction to be proceeded.
When the present invention adopts liquid calcium superphosphate active and porous agent ssp dnae in next life, raising agent enters with sulfuric acid and carries out formula (1) reaction in the mixing reactor, because amount of heat is emitted in the reaction of sulfuric acid and ore pulp, raising agent is heated, adsorbs, flowing forms a large amount of foaies, improved transfer reaction speed between acid and ore pulp, and can prevent that the breeze surface from making hybrid reaction not thorough because of Deposit of Calcium Sulfate, because hybrid reaction is relatively thorough, also correspondingly improved the available phosphorus transformation efficiency.
Beneficial effect of the present invention is: when adopting liquid active and porous agent of the present invention and using method ssp dnae in next life, 1 ton of calcium superphosphate of every production only need add 100 ~ 200 gram liquid active and porous agents, increases only 1.2 ~ 2.0 yuan of costs.Available phosphorus raising 0.5 ~ 1.0% in the bright fertilizer, moisture content reduction by 1 ~ 2%, available phosphorus transformation efficiency improve 3 ~ 7%, obviously improve calcium superphosphate product caking situation, reduce slaking turning number of times, curing time shortening 4 ~ 10 days.The present invention has solved preferably the Production of Single Superphosphate process and has existed water content control unstable, and the curing time is long, and product easily lumps, and the user uses the problems such as difficulty.
