Operating principle

The cyclone purifier integrates the centrifugal and filtering separation technology, to avoid the liquid film cutting, re-atomization, liquid entrainment, entrainment, suction, and secondary crushing. In the separation process, gas enters into the cyclone for rotation under a certain pressure and flows downwards along the axial direction.

Under the action of centrifugal force, large amounts of liquid and solid particles are dumped to the lower part of the cylinder wall, and the gas discharges from the cyclone. In the flow process, the circulation section increases gradually, and speed decreases gradually, and liquid and solid are discharged along the wall, which achieves the gas and liquid or gas and solid separation process.

The gas enters into the outlet pipe after the gas and liquid or gas and solid separation, and flows into the mist catcher for secondary separation. The small drops in gas are condensed into large drops, which fall down depending on their own weight, and into the liquid trap cavity through conduction pipe. Finally, separated solid particles and liquid are discharged from the drain outlet, and the separated gas from the gas outlet.
