Abstract:
A cyclone is provided. The cyclone includes an inner cylinder (300) and an outer cylinder (301). An annular space (302) is formed between the outerwall of the inner cylinder (300) and the innerwall of the outer cylinder (301). The lower end of the inner cylinder (300) is open, and the lower end of the outer cylinder (301) is close. There is an air inlet (303) in the wall of the outer cylinder (301). There is an air outlet (304) on the upper end of the outer cylinder (301). A circumfluence part is provided between the upper end of the inner cylinder (300) and the air outlet (304). Air flow enters the cyclone tangentially through the air inlet (303) on the lower end of the outer cylinder (301). A part of separated air flow is discharged through the air outlet (304), another part of separated air flow is separated again from the circumfluence part through the annular space (302). The separated circumfluence flow enters the inner cylinder (300) and mixes with new ingoing flow so as to be separated once more.
