How should the dust at the top of the granulation tower be dealt with?
In recent years, various types of dust recovery devices have emerged in China, primarily using structured packing combined with washing to recover dust and urea, but the actual performance of these devices is generally average. The poster can consult relevant technology suppliers.
It seems that Ningbo Far East in China has recycling technology, while Mengmok abroad has such technology.
Ningxia and Ning Chemical have completed the acceptance of the urea dust recovery unit! ! !
A new dry dust removal system helps improve the environmental performance of urea granulation towers – achieving 5mg/Nm3. Those interested can get in touch with me. I also posted related messages; currently, the granulation towers at Henan Xinlianxin and Qinghai Yuntianhua in China are operating successfully. Contact number: 13381830668
Nowadays, dust recovery systems are installed in all such systems; otherwise, they fail to meet environmental standards. Flushing water is used with the fillers, and the systems we use work well. In some places, however, the effect of this approach is not good – it’s only used during environmental inspections as a way to meet those requirements. Almost all urea production facilities these days have such systems!
The new dry dust removal system can only handle dust; how to deal with ammonia?
We started using it recently as well; it’s still in the trial phase
From your unit? What is a granulation tower used for?
