Cyclone dust collector

Working principle:
Centrifugal filter (Cyclone Dust Collector) with vertical axis of gas flow rotation in four-channel design.
1. Inlet pipe 
2. Outlet spigot
3. Conical hopper
4. Ring slot
5. Head bottom
6. Curvilinear channels
7. Recirculation slots
8. Separation chamber

The dusty gas stream enters the separation chamber 8 via the tangential inlet pipe 1. Due to the curvilinear trajectory, solid particles are concentrated at the periphery of each of the channels 6 and are discharged from them through the slots 7 into the previous channels in the flow path. From the first and second flow channels 6 dust, together with a part of gas, enters through the ring slot 4 into the cylindrical hopper - dust collector 3, where a large mass of particles settles down, and the lightest (small) fractions, continuing to hover, return through the slots 7 to the zone of active separation (channels) and are separated again. A dynamic gas-dust layer forms as a result of the internal circulating flows in the system of channels, which is a filter for particles newly arriving for gas purification.

Purpose:
For purifying gas-air streams from ash and dust at temperatures up to 450°C and solid particle concentrations up to 1000 g/m³. It is used as a preliminary cleaning stage before scrubbers, bag filters or ceramic filters.
