Clogging problem in cyclone separators
Thread Content
The sulfuric acid an by-product recovery unit in our plant is a set of vibrating fluidized bed dryers; the dried exhaust gas is discharged after passing through a cyclone separator and a scrubber tower. The main problem now is that the cyclone separator gets clogged frequently; the discharge valve operates properly with no air leaks, but it requires frequent cleaning by operators, which involves a high level of physical effort. It is mainly due to poor material flow, and the material factors are difficult to change. Is there any way to solve this clogging problem? Thank you!
Several reverse blowing points for fluidizing air can be installed at the lower part of the cone; it’s important that the air is dry! Otherwise, it tends to clump!
It doesn’t seem hard to make the changes; I’ll give it a try after the holiday. Thank you!
Add a pulse reverse blowing; ours is 15 to 2, with 2 seconds of blowing every 15 seconds. The specific settings will depend on the size of your equipment and the specific conditions
Backblowing is a good method. Based on practical experience, I would like to know whether the moisture content of the sulfuric acid AN produced by the cyclone is the same as that of the sulfuric acid AN produced by the fluidized bed Where is the cyclone placed? What is the water vapor content in the flue gas from a fluidized bed? If it is outdoors, is it possible for the temperature to drop as it passes through the cyclone separator, resulting in dew formation? Moreover, since sulfuric acid an is hygroscopic, issues such as caking can occur! If the backflow effect is not good, discuss it with your technical staff and try insulating the cyclone separator!
