Example 1
The utility model provides an ultra-purification wet dedusting gas washer, includes casing 7, casing 7 internal fixation has motor 9, connect on motor 9's the output shaft and be fixed with impeller 1, still include venturi group, venturi group welding is fixed at casing internal impeller 1's rear, is located the gas passage at impeller 1 hou mian. The venturi group includes the venturi 2 of welding on the casing inner wall of encircleing of predetermineeing quantity. The motor is fixed in the motor barrel 8 through bolts, and the venturi tube group is welded between the outer wall of the motor barrel 8 and the inner wall of the shell. The Venturi tubes 2 in the Venturi tube group are sequentially welded and connected and integrally spliced into a ring shape. Venturi 2 includes constriction 201, throat 202 and diffusion part 203 from the front to back in proper order, and constriction 201, throat 202 and diffusion part 203 are structure as an organic whole, the cross section of constriction 201 is the tubaeform of big end back, the cross section of diffusion part 203 is the tubaeform of big end back, throat 202 is the straight section. Still include swirler 3, venturi nest of tubes rear in the casing is located to swirler 3, swirler 3 includes retaining ring 301 and baffle 304, it has the annular drainage channel towards the casing inner wall to open on swirler 3, the drainage piece 302 of predetermineeing quantity has been arranged in the drainage channel, and drainage channel is the space between retaining ring 301 and the baffle 304 promptly, and drainage piece 302 welds between retaining ring 301 and baffle 304, drainage piece 302 arranges into the ring-type and unifies in drainage channel and follows clockwise or unify along anticlockwise slope, leaves the clearance between the adjacent drainage piece 302. The cyclone 3 makes the fluid pass through the gap between the guide vanes 302 and move backward against the inner wall of the casing in a rotating state. The middle part of the baffle 304 is bulged forwards to form an arc-shaped slope surface, a connecting hole 303 is formed in the center of the baffle 304, the connecting hole 303 is welded on the outer wall of the motor barrel 8, and the outer edge of the retainer ring 301 is welded on the inner wall of the motor shell. The air purifier further comprises a dehydrator 5, wherein the dehydrator 5 is cylindrical, the shell is cylindrical, the dehydrator 5 is coaxially welded and fixed at the rear end of the shell, the inner diameter of the dehydrator 5 is larger than that of the shell, and an air outlet is formed in the rear end of the dehydrator 5.
