Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the spray device of the energy-saving desulfurization tower is suspended in the desulfurization tower, and the desulfurization tower adopts the existing design, which is not labeled in the figures and is not described again.

This spray set includes connecting pipe 1, transition ball 2, a plurality of radial shower 3 of group, spray ring pipe 4, and connecting pipe 1 is located spray ring pipe 4 center line position with transition ball 2, and the terminal and the 2 top intercommunications of transition ball of connecting pipe 1, and each radial shower 3 of group is one end and 2 intercommunications of transition ball, the other end and spray ring pipe 4 intercommunication.

The connecting pipe 1 is connected with an external liquid storage device or a circulating device and is used for inputting liquid to be sprayed;

the transition ball 2 is a transition medium body between the connecting pipe 1 and the radial spray pipe 3;

the radial spray pipes 3 and the spray ring pipes 4 are pipelines for spraying the inside of the desulfurization tower from different directions;

the spray ring pipe 4 is an annular pipe body which is abutted against the tower wall of the desulfurizing tower, and the plurality of groups of radial spray pipes 3 are uniformly distributed in an annular array.

The radial spray pipes 3 are arranged in an inclined mode, the height of the transition ball 2 is larger than that of the spray ring pipe 4, and the radial spray pipes 3 are arranged in an inclined mode from top to bottom from one end close to the transition ball 2 to one end close to the spray ring pipe 4.

The spray ring pipe 4 is provided with a plurality of groups of first nozzles 6 facing inwards, and the lower surface of each group of radial spray pipes 3 is provided with a plurality of groups of second nozzles 7.

The radial spray pipes 3 which are obliquely arranged and the annular spray ring pipe 4 are arranged, so that the whole spray pipes are three-dimensionally distributed, and the trend of the spray liquid is more diversified by the first nozzles 6 and the second nozzles 7 which are arranged on the spray pipes, so that the flue gas and the liquid are mixed more sufficiently and uniformly, and the desulfurization is efficient.
