A circular energy saving water getter with rib baffler includes mounting in it a cylinder with a pair of bafflers formed by cross placed straight sides and elliptic arc sides, an included angle between the baffler and humid air flow direction is 9.5-79.3 deg.. The elliptic arc side contacts with the cylinder wall, at the bottom of the cylinder, a bed frame is designed in round top and square bottom and at the top, a thick cowling is mounted with grating section, the grating square lattice edge length is 5-15%, bed frame height is 1/10-7/10 that of the cylinder diameter, the sum of the height of cylinder and cowling is 1-5 times that of the diameter, ribs are set at the baffler surface facing the humid air flow with radian and direction same or similar to those of the baffler and circular set with honeycomb section is also included. |
