The noise of spray drying
Thread Content
There is vibrating noise in the pipeline at the connection between the spray drying tower and the cyclone separator; what factors can cause this phenomenon? Everyone is welcome to discuss.
The air flow rate in the drying tower is too high, resulting in an excessive amount of dried particles being carried into the cyclone dust collector; these dried particles, driven by the wind force, strike the inner wall of the connection pipe.
Possible: 1) As mentioned above, the air volume is too high； 2) Is the filter element of the tail-end collector damaged? The pressure difference is too low, and the flow rate is too high ； 3) Resonance ；
There is vibrating noise in the pipeline at the connection between the spray drying tower and the cyclone separator. 1. Is it a flexible connection or a rigid one? Generally, a flexible connection is better. 2. The vibration noise may be generated together with the fan connection pipe. 3. Agree that the air volume upstairs is too high, the pressure difference is too low, and the flow velocity is too high. 4. Caused by pipeline failures related to the cyclone separator.
After reading the above reply, I can’t help but say: It’s so unprofessional! With such high air flow, how can the pressure difference in the cyclone separator be low? There is only one reason for this phenomenon. The pipe size is too small, and the high gas flow velocity inside the pipe causes vibration. Similarly, the cyclone separator has also become smaller.
