Abstract
A compound B-Mg fertilizer is prepared from the waste liquid generated in preparing boric acid by sulfuric acid, and features that it contains MgSO4.7H2O (higher than 90 wt.%), Fe (higher than 0.5), Na2B4O7.10H2O (higher than 3) and chloride (lower than 0.14).
Description
The invention belongs to the boronation worker and administer the extension manufacture field of pollution and comprehensive utilization of resources, particularly utilize the waste liquid of Production By Sulfuric Acid Process boric acid to produce composite boron magnesium fertilizer and production technique.
In the past, China's boronation worker leading product were borax, boric acid.And boric acid is produced today, and still major part adopts the vitriol oil and the one-step technology manufacturing of giving birth to boron powder (higher-grade) reaction always.Adopt this manufactured boric acid, the rate of recovery of general producer boron only reaches a new level about 60%, and the major part of recoverable boric acid and a large amount of sal epsom do not emit with waste liquid (mother liquor), both serious pollution environment, wasted resource again greatly.
For solving the recovery problem of boron, more domestic scientific research departments and production unit, once utilized " salt acid system ", the two step method of saltouing, produce the test of boric acid, magnesium chloride or magnesium sulfate monohydrate, but all be not applied in the actual production, domestic also have tame unit test to add the gas washing in SA production boric magnesium fertilizer with giving birth to boron ore powder.
The object of the present invention is to provide a kind of compliance with environmental protection requirements, effect of increasing production ideal composite boron magnesium fertilizer and preparation technology thereof.
Technical solution of the present invention can realize according to following mode:
Composite boron magnesium fertilizer is characterized in: (percentage composition by weight) contains:

The preparation technology of above-mentioned composite boron magnesium fertilizer is characterized in: the waste liquid of Production By Sulfuric Acid Process boric acid as mother liquor, is finished the following step successively:
(1) mother liquor is directly deposited in material-stored pool or the material-storage jar;
(2) utilize submerged pump that feed liquid is added in the vaporizer, utilize steam heating, carry out evaporation concentration, 4～8 hours, the feed liquid of evaporation is carried out the degree Beaume test, when reaching 38～42Be °, in time squeeze into feed liquid in the crystallizer while hot;
(3) after crystallizer is made, open water coolant, cool off, start agitator simultaneously, stir, make it uniform particles, do not form druse;
(4) when from outward appearance to inner essence 100 ℃ when reducing to below 35 ℃ of the feed liquids in the crystallizer, will arrive the feed liquid of temperature and put into the heavy naturally filter of heavy filter pocket, the material adding whizzer with dryer and comfortableer carries out centrifuge dehydration;
(5) will take off the crystal material of water, take out the packing weighing, i.e. the efficient composite boron magnesium fertilizer of output.
The present invention's energy efficent use of resources, compliance with environmental protection requirements has effect of increasing production to farm crop.
