Given the poster’s production capacity, is the granulation tower too small? 1: The most fundamental requirement for a granulation tower is to be able to cool the urea particles that settle at the bottom of the tower to 60–70 degrees Celsius under maximum load. II: It can achieve the same cooling effect at the highest temperature of each year. Third: In the southern regions, cooling must be ensured during the summer, so it is necessary to make appropriate adjustments, namely increases, to the effective height and tower diameter. We recommend our under-construction tower-type urea granulation plant with an annual capacity of 600,000 tons; its granulation tower has a diameter of 22 meters and a total height of 91.7 meters. Effective tower height: 70 meters! Located in the southwest region!
For a urea plant with an annual production capacity of 700,000 tons, the daily production should be around 2,200 to 2,400 tons. If the diameter of the urea granulation tower is only 20 meters, it seems a bit too small; it is recommended that it be at least 22 meters or more ； It is recommended that the effective granulation height of the granulation tower be at least 60 meters. Of course, these values should be adjusted depending on the location of the urea production facility; generally, in the south, where temperatures are higher, it is advisable to use larger tower diameters and a greater effective granulation height ； Conversely, the size in the north can be appropriately smaller to save on investment.
Our urea granulation plant with a capacity of 450,000 tons per year features a granulation tower with a diameter of 19 meters and a total height of 90 meters. Effective tower height: 70 meters! Located in East China!
What height does the effective height of a granulation tower refer to? Is it the height from the louvers to the lower edge of the granulation nozzle? Is it the height from the bottom of the tower to the lower edge of the nozzle, or some other explanation?
The data provided by our sources is the distance from the nozzle to the scraper. I wonder what other manufacturers say. 5# Xingxing Tao
The height from the louver to the lower edge of the granulation nozzle (more precisely, the nozzle layer) is the effective height!
