Be installed at least two-layer pipe row be arranged in parallel of described support frame;
Described pipe row comprise multiple isometric pipe, and the pipe that the pipe in pipe row is adjacent Guan Liezhong is mutually vertical.
Further, described support frame is a quadra.
Further, described support frame height is 150 ~ 600mm.
Further, the porous plate of the side being installed on described support frame or adjacent both sides is also comprised.
Further, described porous plate comprises an outer wall and middle plate; The uniform multiple circular hole of described middle plate.
Further, a side profile of described outer wall and the inwall of desulfuration absorbing tower are fitted.
Further, described Circularhole diameter is Φ 25 ~ Φ 80mm.
Further, described pipe is rotatably installed on described support frame.
The utility model also provides a kind of desulfuration absorbing tower, comprises a smoke inlet and a spraying layer; Have a turbulent flow mounting layer between described spraying layer and flue gas mouth enter, the turbulent pipe grid device that described turbulent flow mounting layer puies forward effect by multiple aforesaid wet desulphurization is covered with.
Further, described multiple aforesaid wet desulphurization carries the turbulent pipe grid device of effect by screw thread handle conjunction structure or pressure plate structure connection.
By taking above-mentioned technical scheme, the utility model takes modularized design, turbosphere is arranged in parallel into by a series of caliber, pipe that length is identical, by two-layer above pipe row arranged crosswise, suitable spread pattern is become according to simulated flow pattern calculation combination, the two ends of pipe are connected with support frame is rotating, can prevent tube wall from occurring scale formation.Whole turbosphere is decomposed into multiple standard module, and the specification of each building block is all identical, can reduce manufacturing cost, reduces the workload of installation and maintenance, is conducive to applying.
