Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
EXAMPLE 1 slurry redistribution Ring for desulfurizing Tower
Referring to fig. 1 to 5, the utility model provides a thick liquid redistribution ring for desulfurizing tower, including tower body 1, be provided with in the tower body 1 and spray the layer, the below that sprays the layer is provided with thick liquid redistribution ring 3, thick liquid redistribution ring 3 includes distribution ring 5 down, distribution ring 5 includes thick liquid import 51 and thick liquid export 52 down, thick liquid import 51 is greater than thick liquid export 52 and thick liquid import 51's bore and tower body 1's internal diameter equal.
And a vertical sliding chute 7 vertical to the ground is arranged on the lower distribution ring 5.
The outer part of the lower distribution ring 5 is welded on the inner wall of the tower body 1 through an annular support frame 10. Preferably, the included angle R between the annular support frame 10 and the inner wall of the tower body 1 is 120-130 degrees.
The spraying layer comprises a spraying pipe 2, and a plurality of nozzles 11 are arranged on the spraying pipe 2.
In order to further improve the protectiveness to the tower body inner wall, thick liquid redistribution ring 3 still includes distribution ring 4, it is the tubular structure of upper and lower constant diameter to go up distribution ring 4, be provided with a plurality of slope spouts 6 on the inner wall of last distribution ring, the contained angle between the axis of slope spout 6 and last distribution ring 4 is 45, and 6 slopes 45 settings of spout, when helping the thick liquid to spray on distribution ring 4, and the thick liquid that drips slides the journey length more, helps forming big thick liquid pearl, the landing of being convenient for. The big thick liquid pearl that forms is drawn into vertical chute 7 along slope spout 6 in, because lower distribution ring 5 is the setting that warp from top to bottom varies, so vertical chute 7 slides down fast under the slope effect of lower distribution ring 5, has stopped the thick liquid and has contacted the problem with the inner wall.
