Vortex chamber top blind flange 3 and the vortex chamber bottom plate 7 of its underpart installation, the chilling ring 5 that is placed in the inside of vortex chamber barrel 2 form
Vortex chamber 13, several inlet tubes 1 and vortex chamber barrel 2 penetrate through, and chilling ring partition 4 is placed in vortex chamber, the upper end and eddy flow
There are channel between top of chamber cover board 3, the spacing in the channel need to form the amount of uniform water film according to 9 inner wall surface of down-comer come really
It is fixed.And 4 lower end surface of chilling ring partition occurs 8 upper surface of mouth partition with external moisture film and connects, which occurs under mouth partition 8
End face is connected with down-comer；It is ring shell structure, the down-comer of inner diameter and quasi- connection that mouth partition 8, which occurs, for the external moisture film
9 interior diameters are equal, and outer wall center is uniformly distributed several for being uniformly distributed the groove of fluid, and the size and quantity of groove need to be according to fluids
Flow and the clean level of fluid determine, the slot bottom of the wall surface of outer wall upper and lower side and the groove for same plane and with quasi- connection
9 overall diameter of down-comer it is equal；Outer layer moisture film protects the upper end of cylinder 12 and vortex chamber bottom plate 7 to connect, and welding or bolt can be used
Mode connects.Lower end is free end, and outer layer moisture film protects 12 length of cylinder that need to be determined according to 9 outside moisture film desired height of down-comer.
It is consistent that outer layer moisture film protects the interior diameter of cylinder 12 overall diameter of mouth partition 8 need to occur with external moisture film.And its inner wall and external water
The cell wall top surface contact of 8 upper groove of mouth partition occurs for film；Vortex chamber partition 6 is mounted on the perforation of inlet tube 1 and vortex chamber barrel 2
Place, is divided into two parts for the fluid flowed through；A part is from the channel between 4 upper end of chilling ring partition and vortex chamber top blind flange 3
Down-comer 9 is flowed to, another part flows into external moisture film and occurs outside the cooling down-comer 9 of groove of mouth partition 8.
Installation moisture film is evenly distributed with partition 10 on 9 outer wall of down-comer of 12 lower section of outer layer moisture film protection cylinder, and the moisture film is uniformly distributed
Partition 10 is uniformly made of the spiral plate of several contour, equal diameters, uniform pitch；And moisture film is evenly distributed with outside the down-comer of 10 lower section of partition
Moisture film diffuser plate 11 is installed, the shape of the moisture film diffuser plate 11 is conical section, if side is uniformly distributed upwards for conical section bottom on wall
Dry groove.The size of conical section and groove is determined by the flow of 9 outside moisture film of down-comer.
The chilling ring partition 4 is ring shell structure, and the upper inside wall of the ring shell structure is thick-walled structure and is in arcuation
Prominent structure, inner wall lower is thin-wall construction, and the end of the prominent structure of the arcuation is provided with the groove for being uniformly distributed fluid,
