[0031] In this embodiment, the guide air duct 19 is located at an eccentric position of the end cover 1, and the guide air duct 19 is formed with a narrow throat portion 11 and an expansion portion 12, and the narrow throat portion 11 is connected to the expansion portion 12; reflux holes 13 are distributed on the outer wall of the inner sleeve 6 and the inner wall of the guide sleeve 5; the reflux holes 13 are structural holes located on the outer wall of the inner sleeve 6 or the inner wall of the guide sleeve 5; the number of inner sleeves 6 is at least one; the outer diameter of the top of the guide sleeve 5 increases from top to bottom; the bottom of the guide sleeve 5 extends to the middle and lower part of the cylinder 2; a plurality of filter channel holes 14 are distributed inside the inner sleeve 6, and the filter channel holes 14 on adjacent inner sleeves 6 are staggered; a drain port 16 is formed at the bottom of the cylinder 2, and the drain port 16 is connected to a drainer 17.
