Dust removal measures for urea granulation towers?
Thread Content
Is a dust removal device installed in the urea granulation tower? What is its performance?
What the original poster is referring to is the dust recovery device at the top of the tower. In previous years, due to environmental regulations, many factories installed such devices, but their effectiveness was generally mediocre.
Well, if environmental regulations require online monitoring at the top of the granulation tower, then it’s certain that the standards won’t be met
We tried it, and the result wasn’t good; when we blocked all the air ducts, the effect was better
Dust removal is achieved through water washing; a fan is required, and once the urea content in the water reaches a certain level, it is sent back to an evaporation section for reuse
Gas-liquid separation packing definitely affects resistance; it has an impact on the temperature of urea. The addition of such packing affects the air flow rate, and the load is affected as well. Without it, trailing effects are severe, and environmental considerations are not met.
A new dry dust removal system helps improve the environmental performance of urea granulation towers – achieving 5 mg/Nm3. Those interested can get in touch with me. I also posted related posts; currently, the granulation towers at Henan Xinlianxin and Qinghai Yuntianhua in China are operating successfully. Those upstairs who are interested can get in touch with me.
