[background technology]
Liquid re-distributor is the parts in flue gas desulphurization system (FGD) absorption tower.
MET company has confirmed the wall flow phenomenon to the test of the unit of different capabilities.Experiment finds, apart from the tower span from as SO
2The function of concentration, SO
2The variation of concentration is very obvious.Begin 0 ~ 1.3m outer circumferential area sprinkle density from the absorbing tower wall less than absorption tower central area, SO
2Concentration is maximum near tower wall or tower wall place; The sulfur dioxide concentration of measuring apart from tower wall 1.2m place is equal to or less than SO in the chimney
2Mean concentration; Apart from tower wall 3m, SO
2Concentration is near 0; Most of tower body central area can reach 99% ~ 100%SO
2Clearance.
The performance test results of installing behind the liquid dispensing apparatus shows, system's desulfuration efficiency can improve 2% ~ 5%
But the structure of existing liquid re-distributor can increase the up resistance of flue gas in the tower, must improve the load of blower fan for this reason.
[summary of the invention]
The problem that exists in order to solve the aforesaid liquid redistributor the invention provides a kind of liquid re-distributor for flue gas desulfur device, and it can not only reduce flue gas in the tower, can also strengthen flue gas at the turbulent flow of Ta Bichu, strengthens SO in the flue gas
2Mass transfer power with seawater.
In order to reach the foregoing invention purpose, technical solution of the present invention realizes in the following way:
A kind of liquid re-distributor for flue gas desulfur device comprises some the first blocks and some the second blocks; The first block comprises oblique triangular prism and baffle plate, tiltedly triangular prism comprise an end face with two with the equal identical bottom surface of end face angle, two baffle plates are vertically fixed on the both sides at end face; The structure of the second block is identical with the structure of the first block, and the length of the oblique triangular prism of the second block is long than the length of the oblique triangular prism of the first block; Some the first blocks are circular layout on the same level cross section of absorption tower inwall in equally spaced mode; Some the second blocks and the first block are arranged on the varying level cross section of absorption tower inwall with interlace mode, and the second block is positioned at the first block below; The width of the end face of the second block is fixed on the gap width between the end of absorption tower inwall more than or equal to adjacent the first block.
The present invention further improves and is: being fixed on the inwall of absorption tower under the first block and the second block all are tilted to by the mode of welding.
The present invention further improves and is: end face and the angle between the inwall of absorption tower of the first block and the second block are 45 °.
The present invention further improves and is: the material of the first block and the second block is stainless steel.
The present invention further improves and is: the angle between two bottom surfaces of the first block and the second block all is less than or equal to 90 °.
With respect to prior art, the present invention has the following advantages: liquid re-distributor of the present invention is that the bottom is wedge shape, and there is the small front apron perpendicular to end face both sides, prevent that the liquid of collecting from flowing out from both sides, adopt up and down 2 grades of interlaced arrangement, the length of the 2nd grade length than the 1st grade is long; The present invention can strengthen flue gas at the turbulent flow of Ta Bichu, improves the gas-liquid mass transfer power of flue gas and seawater, and reduces the flow of flue gas resistance.

Fig. 1 is an independent liquid re-distributor structural representation;
Fig. 2 is liquid re-distributor 2 grades of top views that are circular layout in tower.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
See also Figure 1 and Figure 2, a kind of liquid re-distributor for flue gas desulfur device of the present invention comprises a plurality of the first blocks 10 and a plurality of the second block 20.The first block 10 comprises oblique triangular prism 2 and baffle plate 1, tiltedly triangular prism 2 comprise an end face 101 with two with end face 101 angles all the angle between identical 102, two bottom surfaces 102, bottom surface be less than or equal to 90 °, to reduce the resistance of flow of flue gas in the tower; Baffle plate 1 is vertically fixed on the both sides of end face 101, prevents that the liquid of collecting from flowing out from the both sides of end face 101, can only flow into along the front end of end face 101 middle part, absorption tower.The structure of the second block 20 is identical with the structure of the first block 10, and just the length of its oblique triangular prism is long than the length of the oblique triangular prism 2 of the first block 10.
