Cyclone Separator Design

Posted in: , on 10. Dec. 2014 - 12:23

dear sir,



I have designed the 1000 ltr cyclone separator to collect fine powder (min. 2 micron-40micron).

The vacuum unit having 5000 mmH2O and 2100 m^3/hr at 100mm dia. when I collecting only 60% of the dust collected in the separator.. Others collected in the machine container so that the filter is getting choked offenly...

What should I do: change the size of preseparator or reduce the capacity of m/c..?

Dear Mohan,

Review the design of the cyclone and check the operating parameters.

2 micron is already a fine particle for cyclone separation.

Have a nice day ■

A cyclone is not suitable for collecting powders this fine. Use it as a pre-separator and back it up with a self-cleaning bagfilter or cartridge filter.

Hi Mohan,

There are a lot of different cyclone-designs on the market yet. Seperation efficiency for small particles (1-4 µm) is bad (<40 - 60%). For coarser particles efficiency (5 - 15µm) will increase up to around 95%.

But:

You have to pay for:

-high pressure loss or energy consumption

-high wear

-etc.

If you are interested in a detailed calculation (which costs money), please ask for.

Best regards
