Description
Technical field
The present invention relates to urea to store anti-caking intelligence in regulation and control method and technology field more particularly to a kind of urea storing process
Method can be regulated and controled.
Background technology
For water-soluble solid, it is not absolutely dry at the surface for contacting humid air, but covers one layer
Very thin solution film, the concentration of solution is equivalent to saturated solution concentration at this temperature on liquid film.It is let off in urea storage and transportation and heap
Cheng Zhong, particle surface are in close contact；With the variation of urea granules temperature and ambient air humidity, particle surface occur moisture absorption or
The process of evaporation leads to Particle Breakage, and particle can recrystallize in the liquid film of surface under extraneous extruding.Newly crystallize
Urea is bonded together with other crystallizations, and here it is the reason of caking.Therefore, to prevent urea from being tied in stacking or storage and transport process
Block, it should carry out control from following several respects：1st, by the moisture of urea product and temperature control in optimum range；2nd, by environment
Dust Capacity control in optimum range；3rd, by ambient humidity control in optimum range；4th, urea stacking height is controlled
Reasonable altitudes, prevent from pushing that pressure is excessive causes to lump.But existing urea warehousing system, can't be comprehensively and intelligently to urine
The stacking of element is highly detected and adjusts, and causes urea from caking to a certain extent and influences function and effect and the storage of urea
Effect.
