Description

Categorised collection device with urea large granule truns into mesoparticle

Technical Field

The utility model belongs to the technical field of chemical production, concretely relates to trun into categorised collection device of mesoparticle with urea large granule.

Background

The granulation of urea with a fluidized bed is known. This method involves spraying fine droplets of a high concentration, typically 96% or more, urea solution onto fluidized bed particles. The urea solution is also called growth liquid of the fluidized bed. Small solid particles (generally less than 2mm in diameter) of the same or different substances, called seeds, are also fed into the fluid bed, thus acting as an initial point for the continuous deposition of the growth liquid to facilitate the granulation operation. The seeds and growing granules of urea then form a bed. Typically, the fluidization process is carried out under air.

In conventional processes, the particles transported by the fluidized bed are screened and oversized and undersized particles are used as seed material, e.g., undersized particles are directed back into the fluidized bed and oversized particles are crushed for further production of seed material. Along with the international urea price reduction in recent years, the profit margin of the urea market in China gradually becomes smaller, most of domestic urea manufacturers lose, and because the land of China is reclaimed, the soil nutrient imbalance is caused by the mass use of urea as a nitrogen fertilizer or an additional fertilizer, the soil nutrient condition is worsened due to soil erosion, excessive reclamation predation type operation and industrial and agricultural production, the fertilizer has short fertilizer effect period, unbalanced nutrient supply and unbalanced nutrient supply, in order to meet the market requirement and convert the large-particle urea into medium-particle urea, a urea workshop firstly adjusts the sizes of the upper and lower layer screens of the vibrating screen, although the product particles meet the standard requirements of the medium particles, the product particles have the defects of more returned material crystal seeds, short operation period of the device and poor classification and collection of urea particles with different sizes, so that the medium particles are low in collection amount and need a large amount of manpower and material resources.
